How is the Portascanner® 520 used to supplement the use of the Door Fan Test kit?

How is that done in a test?

Answer: Before or during the Door Fan Test, the goal is to obtain an overall understanding of
how much the room was leaking. The process to do this starts off by turning the ultrasound
emitter on and leaving the emitter in the room. Exit the room and look for areas which
commonly leak and use the receiver to pinpoint the exact position of these leaks where leaking
ultrasound would be detected. The leak tests can be done on doors, raised floors, cable
penetrations and out of air vents. Some wall areas can also be quickly checked by running the
sensor wand across. These leaks can be promptly sealed before the Door Fan Test equipment
is brought in or before the Door Fan Test is repeated

How can the more challenging areas of an enclosure be tested for leakage areas such as raised floors and false ceilings?

Answer: If the leakages from the room into the void area above the false ceiling need to be
found, one can locate the leaks in the ceiling tiles by placing the compact ultrasound generator
in the void area and scanning the false ceiling tiles below using the receiver.
If the leakages above the false ceiling tiles leading to the adjoining rooms is more of a concern,
then the important leakage areas to note in the ceiling void are areas close to the air vents or
cable penetrations that leads into the adjoining rooms. The ultrasound generator placed within
the room will fill the room with ultrasound allowing these areas to be tested from the adjoining
rooms.

When testing leaks that go from areas underneath raised flooring into the adjoining rooms,
the ultrasound generator can be placed underneath the floor tiles and the leaks tested outside
from the adjoining rooms. Examples of areas to note are areas where cabling exists between
the adjoining rooms. The ultrasound generator placed underneath the floor tiles will fill the
entire area with ultrasound and the leaks from the cable penetrations can be tested by pointing
the receiver towards the cable exit in the adjoining room.

How can the Portascanner® 520 assist with Room Integrity/Door Fan

Tests?

There are 3 areas where the Portascanner® 520 will assist you in your Room Integrity Tests /

Door Fan Test (DFT):

  1. Pre-Room Integrity Test

Based on the assumption that many rooms fail their initial Room Integrity Test, the handheld

Portascanner® 520 will assist in:

  • EARLY ANTICIPATION OF ISSUES: Portascanner™ 520 enables fire contractors to

indicate location and extent of leak sites prior to a scheduled DFT session for

remedial action to be taken to maximise the “PASS” rate the test.

  • ADD TO RANGE OF SERVICES: Ultrasonic technology can add great value to the

contractor’s range of services by finding and patching up leaks before the

scheduled DFT test day. This is because sealants take time to set and may impede

the operations of a DFT if remedial work is conducted on the DFT scheduled day

itself.

  • MORE ACCURATE SERVICE QUOTES: Benefiting fire contractors and customers – as

ultrasound is fast and non-invasive, a quick ultrasonic leak survey can be conducted

on site to locate early leak sites. This information can assist the fire contractor’s

quoting process and may act as preliminary evidence to justify the quote proposed.

Overall, this practice improves the prospect of securing an initial DFT “PASS” – and

thus delivering up an efficacious fire protection outcome.

  1. During Room Integrity Test
    • EXACT & QUANTIFIABLE LEAK LOCATION: Use of ultrasonic technology can pinpoint

the exact location and extent of the leak sites while the DFT is being carried out.

      • TIME EFFICIENT: As ultrasound is quick and easy to use, the use of a Portascanner®

alongside DFT allows remedial work to be conducted immediately.

      1. Post-Room Integrity Test

Based on the assumption that the structural integrity of rooms will change over time, the

handheld Portascanner® 520 will assist in:

      • REGULATION COMPLIANCE: Once the room has passed the DFT and is able to

achieve the retention time required, periodic ultrasonic room integrity tests can be conducted

using an ultrasound scanner to comply with enclosure integrity maintenance as

listed in the ISO 14520, EN15004 and NFPA regulations.

room can remain continuing their daily tasks without affecting the leak detection

test results

What are bearings and how are they used?

Bearings are an integral device widely used in machinery that requires rotational, axial or linear movement to operate whilst restricting motion into a designed path, minimising friction and stress. Many industries have machinery that requires some form of motion enabled by bearings. Such as:

Steel production facilities

Steel and iron use cold rolling mill machi-nery. The working rolls of the plant are the most extensively monitored. This is quite a challenging monitoring environment due to high temperatures, high and low-speed operation, as well as high contamination of water and debris.

Mining industry

Slow turning rolling element bearings require monitoring in this industry. Machinery such as crushers, stackers, conveyors, vibrating feeders, magnetic separators, slurry and vacuum pumps, classifiers, agitators and compressors.

Paper processing Industry

Papermaking machine bearings operate under very high temperatures and can be vulnerable to fractures of the inner ring, causing stoppages in production. Monitoring is done to determine the condition of the rolling-element bearings of the rolls, roll alignment, balance, and the condition of the electric motors and gearboxes.

Cement industry

Many machines in this industry require monitoring of bearing condition, including crushers, mills, separators, roller presses, separators, conveyors, feeders, air compressors and fans. Most of which use rolling-element bearings powered by electric motors.

Thermal power industry

Gas and steam turbine generators and combined cycle plants require their most critical machines monitored. Dynamic rotating machines use high-speed rotating parts. The cost of failure in this industry is far-reaching.

Maritime industry

Diesel engines, gas turbines and nuclear reactor powered ships utilise bearings in all areas, from crankshafts to pistons and pumps. Also, gearboxes fans and other motors onboard, such as alternators used to generate electricity.

Strive Towards Innovation

Gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use, shown in the regulations that demand their upkeep e.g. IMO SOLAS FSS Ch5. 2.1.1.3. The systems are pressurised approximately 24-29 bars, higher than a standard cup of water which is 1bar. It’s accepted that these systems are not passive but dynamic, thus requiring monitoring. The traditional method requires turning the system off, dismantling and manually weighing each cylinder on industrial scales. Routine maintenance is liable to be overlooked because the crew is unqualified to test or insufficient attention is given by the owner of the system. It’s neglected to the peril of the lives of occupants of the ship and at the risk of crippling financial and reputational loss to the cruiseliner.
Innovative methods of inspecting leaking cylinders with ultrasonics, enables identification in under 30 seconds using Portalevel® with one person, instead of the traditional 15 minutes, with two people labouriously weighing. Using ultrasonic liquid level indicator technology - to pinpoint the liquid level of suppressant agent in the cylinders of the extinguishing system- testing is quicker and easier.

The MAX Marine is designed primarily for maritime applications where either third party service companies or the vessels’ crew themselves inspect large fire suppression systems of up to 600 cylinders. The ease of operation in comparison to weighing, increases the ability of more regular and frequent checks, improving fire safety management onboard. Portalevel® MAX  enables its users to go above and beyond minimal regulations compliance, thus becoming industry leaders.

Coltraco finds success in supplying the global shipping network with the assistance of international partners and ODAs, who provide local support to customers. Coltraco strive towards creating innovative and effective equipment to provide a level of safety that goes beyond regulations. Coltraco designs, manufactures and supports a world-leading range with a technological basis in ultrasonics.

People are priceless

Given that 400 million European passengers every year entrust themselves to the safety of the ship that they travel on, any accidents on board are serious threats to the safety of those passengers. About 6 per cent of fires on ro-ro passenger ships have resulted in loss of life or serious injury and every year. In December 2014, 11 people were killed and several were injured in a fire aboard the Norman Atlantic ro-ro passenger ship. Chances must not be taken when lives are at risk, and when a vessel is at sea, this is all the time.

Protecting the merchant fleet

Research coordinated by IMO has indicated that between 30% and 50% of all fires on merchant ships originate in the engine room and 70% of those fires are caused by oil leaks from pressurised systems. There are generally two types of engine room fires: oil or electric. Engine room fires are one of the most common fires on ships due to the running machinery, and sources of fuel and ignition within them. Oil fires are the most serious. Mechanical issues such as fracture, fatigue failure and also under-tightened components or seals may result in catastrophic occurrences.  Furthermore, it was noted, that high pressure fuel delivery pipes should be covered with jackets capable of containing leaks in case of pipe failure. There is a call to respond to regulations with a rigorous attitude, to go above and beyond, to provide security of life and vessel.

Complying with fire safety regulations does not guarantee safety.

The UK P&I Club have suggested that extended periods of time on board a ship without a fire incident can lead to complacency and therefore a failure of prioritizing prevention methods and fire incident practices.  It is impossible to prepare for all eventualities on a vessel, and it is often easier to influence the prompt detection of fires and their effective extinguishment, and these factors therefore play a key role in minimising fire damage aboard vessels. Yet, one of the reasons why accidents are still happening and fire safety is still a major issue in the shipping industry is the lack of development in firefighting equipment available on board container ships.

Contain the risk of fire

Vice Chairman’s of the International Union of Marine Insurance (IUMI) stated that to global shipping, major fires on container ships are among the worst hazards. Part of the problem is as container ship sizes have increased, the firefighting equipment on board has not experienced the same development. In their 2015 annual report, the USCG identified that the greatest deficiency onboard ships was its firefighting appliances.  An example of where the risk has become a danger is the CCNI Arauco. On the CCNI Aruco, 300 firefighters were needed after an unsuccessful seal and flood of the vessels hold with CO2. The hatch had to be flooded and then foam was used to bring the fire under control. The main difficulty comes from the inadequate equipment which the crew had to tackle the fire and as a result there has been calls for the technology to change.

Case study: Engine Room Fire 2009

  • An incident occurred on 9th January 2009 when a fire erupted within the engine room, as the ship was en route from Ulsan to Ningbo.
  • The probable causes were identified within the investigation as a failure and explosion of the main engine crankcase.
  • This failure resulted in large quantities of hot oil mist and flammable vapour in the engine room which was then ignited.
  • Overall, it was found that there were many issues regarding the state of the engine, but also with the maintenance and inspection of preventative equipment such as fire safety equipment and also a lack of leadership qualities shown by the crew masters and security managers.
  • In terms of the fire safety, the investigation showed that even though the fire detection and alarm systems were installed and previously inspected three months beforehand, both had failed during this incident, thus not alarming the crew at the appropriate times.
  • This was due to improper maintenance.
  • This result demonstrated that regular inspection fails to prevent failure if maintenance is inadequate.

Ultrasound

Largely used in shipping as a tool to gauge thickness, yet with more varied uses across military, medical and industrial fields - is now being put to more advanced, innovative uses in shipping for fire safety solutions too.

One of the sciences being harnessed by innovators in the fire safety sector is that of Ultrasound: i.e. acoustic (sound) energy in the form of waves of high frequency that are above the human audible range. Although the shipping world merely uses it as a tool to ultrasonic thickness gauge, it has seen far more varied use across military, medical and industrial fields. Sound is, in itself, vibrations that propagate as a mechanical wave or pressure and transmit through solid, liquid or gaseous mediums. Coltraco is one of a number of companies using these fundamental physical principles to design and manufacture products and systems that can be used by fire engineers and their customer installations. 

Today we know this as SONAR. Ultrasound is sound beyond our audible range. We are familiar with it through our hospitals during pregnancy scanning or the BBC when we “hear” dolphins and bats using it to communicate and navigate on wildlife programmes. We only hear that on our televisions as the ultrasound is hetrodyned to convert the ultrasound into something we can hear. But just as sound travels more quickly through water than air we understand that it travels through both. And its speed of travel can be measured. And because a gaseous system contains liquid or gas and it discharges into a protected space, so too can ultrasound be used to monitor all 3 of these

As the world changes, so must our industry integrate technological solutions to provide a bulwark against wider industry misinterpretation and minimal, even occasional and flagrant, disregard in the application of standards and good global engineering practise, creating standards which all can understand and apply.

How can crew test their CO2 installations without disturbing them?

As stated in IMO SOLAS FSS Ch5. 2.1.1.3: “Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the container”

Often this is misunderstood, this code specifically states that the crew must test their extinguishing installations in between the periodic inspection, maintenance and certification. Only having the annual inspection by accredited marine servicing companies is not enough – the crew must take responsibility for its own fire protection.  However, what must be noted is that the crew are often not trained or certified to shut-down, dismantle, weigh and re-install the gaseous cylinders. To overcome this, ships need to test their CO2 systems for contents in-between the annual certification checks by marine servicing companies.

Using an ultrasonic liquid level indicator is the only way that the crew can safely test their CO2 without disturbing them. Coltraco Ultrasonics designed the Portalevel® MAX Marine & Portamarine® ultrasonic liquid level indicators, as radioactive units were being phased out. If shipping companies implemented the IMO SOLAS FSS codes by testing safely and quickly (just 30-60 seconds per cylinder) by using liquid level indicators and marine servicing companies were able to do their work without allowing for time pressures, then marine safety would be far safer.

Solutions for any vessels marine gaseous extinguishing system exist:

  • Portalevel® MAX Marine liquid level indicators used by the crew weekly to test for contents
  • Portascanner® WATERTIGHT, watertight integrity test indicators used by the crew to test for compartmentation
  • Portapipe® pipework integrity indicators used to test for pipework obstructions and the Portagauge® thickness gauges for pipework corrosion
  • Compressed air testing of the pipework and flanges to test the pipework system’s ability to withstand the pressures of the gas on actuation (and this is the only test which recommended to be solely the responsibility of a  “responsible” shore-based contractor)

Principal Cause of Cargo Damage: Leaking Hatch Covers

Leaking hatch covers are generally accepted as a principal cause of cargo damage. Hatches leak for a variety of reasons, but mainly because of poor maintenance or failure to seal them properly after loading. Leaking or badly maintained hatch covers can lead to more serious consequences than wet cargo such as flooding, accelerated corrosion or even loss of the ship. Improper sealing of hatches can lead to water ingress, which may cause damage to cargo or even catastrophic loss of life and vessel. This is supported by another report on hatch covers tester from 2001 that “hatch cover deterioration or mal-operation could jeopardise the lives of seafarers and may contribute to the loss of vessels. 33% of large claims by value in general cargo and bulk carrier vessels are caused by leaking hatch covers. Even on new ships, hatch covers may only be truly weather-tight in the static "alongside" condition and cannot be guaranteed in dynamic sea state conditions 

The Swedish P&I Club has noticed that there is an increased number of costly wet damage claims. These claims are most commonly seen on bulk carriers and container vessels. Wet damage claims make up 19.56% of claims in total. The poor condition of cargo hatch covers is often the reason behind this. The Swedish P&I Club have pushed for more preventive measures for cargo hatch cover issues, including regular ultrasonic tests on cargo hatches. Successfully, Coltraco have designed the Portascanner® WATERTIGHT, a portable Ultrasonic Watertight Integrity indicator – for testing watertight and weather-tight seals. This is designed primarily to enhance the ease and accuracy with which critical watertight, airtight or weather tight seals can be inspected for leak sites or areas of reduced compression in the seal. The ultrasound generator emits a modulated signal of a specific frequency of ultrasound (in most cases 40,000Hz). The receiver then picks up the signal and converts it into a result indicating watertight integrity

Maintenance of compartments and importance of hatch coversa

A dry freight convey is a kind of holder or mass transporter having two or three load holds or spaces where it can suit the payload. All store holds in such ships are equipped with a solid made best which is known as incubate covers.
Usage of Hatch Cover: Cargoes and Products holds are managed, these deliver spreads to keep the contact of payload with external condition i.e. air, air and water and to keep away from stack from getting wet. Another fundamental commitment of hatch cover is to keep up the watertight trustworthiness of the ship at all ocean condition by not permitting any path of water inside the compartments of payload and irritating the unflinching nature of the ship. Before you are set up to leave, guarantee you have done ultrasonic hatch cover testing.

Requirement for Hatch Covers: Hatch covers of cargo hold are everything considered conveyed using high versatile steel or lightweight steel. They are settled over a steel bar of the specific load hold with adaptable pressing delved in the midst of them to evade water entrance. A particular routine help to be worked by careful officer from the group on send which ought to fundamentally join.

  1. Hatch cover testing for any parts, disintegrations, and breakage and material issues.
  2. Keep best clean of deliver covers and each waste opening to be kept clear.
  3. Keep pulling wire, rollers, chains, spikes and wedges in operational condition round the clock.
  4. Look for any missing gasket or broken and supplant it quickly while the length of restored gasket must be smallest 1 m.
  5. Before restoring adaptable gasket, check and change steel to steel blame.
  6. Gasket adaptable to be of grasped sort by class.
  7. Do not disregard to oil or oil all the moving parts.
  8. Check for any weight driven structure spillage if cover is worked by oil.
  9. Oil test to be performed for water driven structure.
  10. Call surveyor after any basic repair in the cover and its concerned zones.

Immensity of Hatch Cover Testing: It is greatly fundamental to have hatch cover testing to take out the test before setting without end for the trek. It is useful to repair each something beforehand you leave as it gives you better space and time to give nourishment any emergency or broken parts/things. In addition, this test empowers you to grow your capability and get the trust of clients for progress immovable quality and business.

Enable Your Crew with the Portalevel® MAX Marine

Coltraco Ultrasonics has developed a range of solutions to speed up the cylinder-checking process without compromising on safety standards. The company manufactures two particular tools specifically for this purpose: the PortalevelÒ MAX Marine and the PortasteeleÒ Calculator application. Used in conjunction by a single person, Hunter claims, these two products can enable crew to identify a leaking cylinder (or one that has previously leaked agent) within as little as 30 seconds.

The first step is to place the Portalevel MAX Marine Calculating fire suppression agent weight the side of the cylinder. This andheld unit fits in the palm of the hand monitor pings an ultrasonic signal into the cylinder, which allows the user to “pinpoint the liquid level of suppressant agent”, Hunter says. In this way, the liquid level height has been obtained under 30 seconds for a competent user.

However, it is not a given that the user will know how to convert this figure to determine the weight and mass of the extinguishing agent – nor that they will have the time to sit down and manually calculate hundreds of such readings. The second step, then, is to feed the data captured by the Portalevel MAX Marine into the Portasteele® Calculator app. Hunter elaborates: “The app is installed on a  ruggedised 7” tablet. The user inputs information related to: the extinguishing agent type [ie, CO2, Novec 1230, etc]; the cylinder dimensions; the temperature of the agent; and the liquid level height. The Portasteele® app then instantly provides the agent’s weight.” This process can also be conducted vice versa, inputting the suppressant agent’s mass/weight to generate a reading for liquid level height. This data can then be logged and saved for future transfer to a PC or similar device, so that operators/owners and crew can prove that they have carried out adequate checks in compliance with existing safety regulations and in fact going above and beyond them.

What is the Safeship concept?

Coltraco Ultrasonics implemented the Safeship® concept, to promote protecting critical infrastructure at sea. Bad industry practice is unacceptable when fire risk may have catastrophic results due to risk to life, downtime in operation due to ship safety and repair work and incalculable reputational damage. The crew, cargo and vessel must be protected when at sea because it is it’s own fire brigade without accessibility to typical emergency services. This is a call to respond to regulations with a rigorous attitude, to go above and beyond, to provide security of life and infrastructure.

As a result, Coltraco designed the FLEETSAFE: a package of innovative safety tools to combat the above and comply with regulations

  • An ultrasonic watertight integrity tester
  • An ultrasonic thickness gauge
  • A bearing indicator
  • An ultrasonic liquid level indicator
  • A calculator which converts liquid level readings to weight.

With this package the hatch-covers, doors, MCTs, compartments, pipework, hulls, bulkheads, rotating machinery, pumps, sprinkler systems and gaseous extinguishing installations are protected. The package is based on integrity, from design, through to life-time support, and is accurate, reliable and easy to use for any crew members.

Standardisation in the Shipping Industry

Standardisation is required in the shipping industry to allow for confidence in technology by operators. Common standards ensures consistency, which promotes safety and efficiency. Standardisation is key to streamline processes and in the exchange of data – when utilised this will allow the shipping industry to embrace the huge potential that digitalisation has to offer the shipping industry.

Shipping needs to adopt an approach such as the aerospace industry, which is affected by international cooperation and strongly controlled by national and international regulations and standards in order to ensure safety, reliability, and cost-efficiency. In the aerospace industry, the Federal Aviation Administration and European Aviation Safety Agency generate the regulations and the airlines and member state national civil aviation authorities, such as the UK Civil Aviation Authority and Maintenance, Repair and Overhaul services implement them. A failure to certify that they have been implemented will result in an aircraft not being certified to fly.

In shipping the International Maritime Organisation (IMO) generates many of the regulations and its member flag states, such as the UK’s Maritime and Coastgaurd Agency, are expected to implement them. Indeed, they are subject to interpretation by them. The single most useful thing that the UK could do for shipping globally is to lead at the IMO so that its regulations are implemented through standardisation.

Case Study:

Speaking in from the expertise of Coltraco Ultrasonics (in the monitoring of gaseous extinguishing systems), below is an example of how standardisation will allow the shipping industry to become safer and ensure the implementation of regulations.

The regulations that currently govern gaseous extinguishing systems are the IMO SOLAS Fire Safety Systems (FSS) Code and the BS EN ISO 14520 standards. These require that the liquefied gaseous cylinders be checked for an agent loss of more than 5%, at which point they should be refilled or replaced.

Standardisation means that the crew have a responsibility to implement the regulations via regular testing, which enabled through smart ultrasonic technology and Internet of Things (IoT) IoT, should be done continuously to avoid negligence and unnecessary risk.

Smart technology provides the crew and ship owners with ease of inspection and understanding their extinguishing systems. However, the crew will not be able to refill the gaseous extinguishing system, and instead must rely on notifying the marine servicing company when they arrive at a port, despite the fact that they may only be at the port for a very short amount of time. Due to time pressures, the risk of not being able to find a contractor in time to fill the cylinders in the event of leakage is one that could jeopardise the safety of the entire ship when it is time to set sail.

Continuously monitoring the cylinders with ultrasonic level sensors that utilises IoT can avoid this, because the network contribution. Using IoT enables the advance notification of the crew and shore based services whilst at sea. Therefore, preparations to address the issues can be made prior to docking to ensure the issues are resolved given the minimum time they have.

Although the implementation of the IMO SOLAS FSS and ISO 14520 codes with continuous monitoring and IoT could drive up costs of purchasing and installation, the long-term savings and benefits far outweighs the initial cost.
But for this to work seamlessly, there must be a standardisation so that the data that is received by shore-based operators from the vessel, is understood and actioned upon as per the IMO regulations. As shown by a new paper from DNV GL standardisation can enable the effective collection, storage, exchange, analysis and use of data, while contributing to improved data quality and sensor reliability in the maritime industry.

The Need for Advanced Safety: Nuclear Power Plants

Continuous improvements and maintenance are required of the fire safety systems at nuclear power plants due to the safety critical nature of the site. Incidents in nuclear power plants around the world have continued to demonstrate the vulnerability of safety systems to fire and its effects. The potential danger from an accident at a nuclear power plant is exposure to radiation to the people in the vicinity of the plume from the cloud and particles deposited on the ground, inhalation of radioactive materials and ingestion of radioactive materials. It is for this reason that the safety demands of the Atomic Energy Authority must be met.

The Dangers Presented by Fire

The International Atomic Energy Authority state clearly in the Fire Safety in the Operation of Nuclear Power Plants standards that the effects of a single failure in fire safety systems, such a system not performing its required function, can be detrimental.

One example of this is the Chernobyl disaster a catastrophic nuclear accident which cost approximately 18 billion roubles and had a huge human impact. In this disaster a combination of inherent reactor design flaws, together with the reactor operators arranging the core in a manner contrary to the checklist for the test, eventually resulted in uncontrolled reaction conditions that flashed water into steam generating a destructive steam explosion and a subsequent open-air graphite fire. This fire produced considerable updrafts for about 9 days, that lofted plumes of fission products into the atmosphere, with the estimated radioactive inventory that was released during this very hot fire phase, approximately equal in magnitude to the airborne fission products released in the initial destructive explosion. Over thirty years later and investment into the site is still required, with Flamgard Calidair providing fire shut off dampers to the Chernobyl, as part of an €1.5 billion multinational engineering project.

With fires at nuclear power plants still occurring, such as the 2017 power plant explosion at Flamanville, deemed “very serious” by industry experts, the call for advanced technology is of most importance. A significant technical issue led to a blast in the turbine hall in the unit, although there was no radioactive leak, a thorough investigation is being conducted into the concerning event.

Going Above & Beyond Standard Compliance

Coltraco Ultrasonics have met this demand with their provision of continuous monitoring to the gaseous extinguishing systems at power plants, offering a means to go above and beyond existing standards. The International Atomic Energy Authority rigorous standards are clear in their demands:

“2.13: Effective procedures for inspection, maintenance and testing should be prepared and implemented throughout the lifetime of the plant with the objective of ensuring the continued minimization of fire load, and the reliability of the installed features for detecting, extinguishing and mitigating the effects of fires.”

Three of the fire protection measures stated in the standards that should be regularly inspected, maintained and tested are:

- passive fire rated compartment barriers and structural components of buildings, including the seals of barrier penetrations
- a supply and distribution pipe
- gaseous and dry powder fire extinguishing system

Safesite Solutions: the future is 24/7 constant monitoring

Faced with this problem, a leading UK Nuclear family approached Coltraco Ultrasonics in 2003 and commissioned the first Permalevel®. Focused on continued advancement of safety technology, Coltraco have now developed the Permalevel® Multiplex, a fixed fire suppression monitoring device, designed for permanent contents verification. The Permalevel® Multiplex is designed to ensure that fire suppression systems are always fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire at a nuclear power plant.

The application of the Permalevel® reaches further, with customers using this equipment in alternate specialist and confidential manners to ensure safety in the station. With guaranteed systems operations, adaptability for purpose, 24/7 remote access to the systems status, an interruptible power supply and remote real-time monitoring, the Permalevel® offers the efficiency that is now a requirement at nuclear energy sites. The likes of the Atomic Energy Authority asked Coltraco Ultrasonics to tailor make them a solution to constantly monitor a special application using the Permalevel® Single Point for over 10 years.

The Portascanner® 520 is the most mathematically accurate device available providing precise data concerning leak locations and aperture. It is unrivalled in its precision, non-invasive methodology and ease of use, and is the first unit of its kind to be available for a holistic approach to fire safety in complement to Coltraco’s range of equipment for testing fire extinguishing systems.

It is perfectly positioned to work alongside Door Fan testing in order to meet the total requirements for fire safety regulations and ensure the continuous fire protection of rooms using Clean Agent Fire Suppression systems. As Door Fan Testing has been proven to be a reliable and trusted method of room testing by industry experts, it is expected that its dominance shall continue in the near future. The immediate use of the Portascanner® lies in its improvement of the final stage of ultrasonic room integrity testing – the search for leak sites in the case of a leakage excess – for which it can vastly improve accuracy and operational efficiency. A device such as this has never been used before in this industry, and is the first to place emphasis directly on this important aspect of room integrity testing.

With Systems Comes The Requirement of Maintenance

There is a clear trend toward including fire suppression in newer units, but with systems, comes the requirement of maintenance. The assumptions in the installation, commissioning and maintenance of gaseous extinguishing systems are that they are highly pressurized and thus risk leaking and discharging, hence why annual inspections are required. 

Large wind companies, such as E.ON, have now begun investing in both in-house and third party operations and maintenance, driven by safety and quality concerns. Inspection should include an evaluation that the extinguishing system continues to provide adequate protection for the risk. This is essential under ISO 14520 where gaseous extinguishing systems have to be designed in relation to the discharging agent hold-time (if the room cannot hold the agent because of leaks the agent will disperse and not extinguish the fire) and discharging agent peak pressure (if the pressure is too high for partition walls or suspended ceilings they will be blown apart or damaged and possibly destroying the room integrity).  However, routine maintenance is liable to be overlooked or given insufficient attention by the owner of the system.

ARE ANNUAL CHECKS SUFFICIENT IN RISKY ENVIRONMENTS?

Given that offshore wind parks require huge investments and are difficult to reach in the event of a fire, an emergency automatic fire extinguishing systems is a must for insurance cover. But what if the suppression systems that are installed in the turbines to protect life and infrastructure do not release on actuation? Gaseous extinguishing/suppression systems are installed to protect against special hazards in critical infrastructure as their key objective. They deliver the infrastructural resilience that wind turbines require. If it is a known fact that there is a long response time to wind turbine fires, then it is unacceptable that the dynamic suppression systems are left unattended 364 days a year.

A CALL FOR CONSTANT MONITORING OF WIND TURBINES

There is a call for remote fire alarms in the turbines due to the lack of easy fire servicing stations, so why not also for the gaseous systems? Why have an alarm system to alert fire services of the fire if the protection system cannot secure the nacelle?   A dynamic system needs monitoring.  The reality is that gaseous systems are checked for contents annually because they are pressurized and anything that is dynamic offers risk of loss of contents, but this fails to deal with the probability of discharge or leakage for the 364 days per annum in the interim between certification checks.

Gaseous extinguishing/suppression systems are installed to protect special hazards in critical infrastructure as their key objective. If the hazard is special and the infrastructure critical then this is the case for the constant monitoring of the suppression systems that aim to deliver the protection of them.

Coupled to this is a complete lack ultrasonic room integrity testing after the gaseous system has been installed. As buildings age or their internal use is changed leak sites develop. If the gas cannot be “held” in the room on discharge during a fire event the probability of its suppression diminishes in direct proportion to the size of the leak sites.  Room integrity tests are imperative for the determination of both the Hold-Time and the Peak Pressure needed for successful fire suppression.

The level of leakage is carefully monitored in order to ensure the correct agent concentration is achieved; room integrity must be ‘tight’ enough to ensure sufficient retention time according to NFPA Standards or ISO 14520, yet remain ‘loose’ enough to prevent enclosure damage at discharge.  The presence of undesired and unregulated leak sites reduces room integrity and will hence dramatically impact the Hold Time and Peak Pressure, placing room contents and potentially wall structures at risk. It is accepted that in wind turbines vibration can loosen connections while dirt, dust, and temperature extremes are known to cause unwarranted discharge. Additionally, openings in the turbine housing significantly inhibit achieving the designated agent concentration. Devising a solution to overcome these challenges can add significantly to the weight in the turbine.

Improve Your Efficiency and Lower Your Costs

Industries across the world use transformers across their facilities. These transformers come in a wide variety. It is imperative to check the oil levels inside to ensure they run smoothly and increase the long-term operation by improved maintenance. Testing oil levels is difficult to achieve traditionally. But today, ultrasonic technology enables non-destructive testing to be conducted by testing from the exterior, non-invasively.
The Safesite® solution is Portalevel® MAX INDUSTRIAL, the world leading handheld ultrasonic liquid level indicator. The likes of utilities companies and hydro from London to USA to the Middle East are using this product to solve their needs and enhance their maintenance measures.

Background

Transformers are used in electric power transmission and distributions and are devices that transfer electric power at different voltage levels. The main components within the transformers are the core and windings which are oil immersed. An oil conservator and Buchholz relay is also commonly found to monitor oil levels. Their combined function accommodates expansion and contraction of the oil in the main tank due to temperature changes or fault and also to provide audible alarms when the oil level falls below the minimum due to any leakages.

As transformers age, they become more likely to lose internal oil. It is important for oil levels in the transformer main tanks to be full, as they act as an insulator and allows the transformers to function efficiently. For transformers that are not fitted with an oil conservator or Buchholz relay, few means of oil level inspection exist and traditional methods include inspection by opening the lid of the transformer.

Portalevel MAX application 1

Application – issues with traditional inspection methods: When the lid is opened, the insulating oil is exposed to the moisture in the atmosphere and will increase the rate of oil deterioration causing the life of insulating oil to shorten. Shortened life spans lead not only to more frequent oil changes, but also significant downtime to the system when an oil change is conducted. Moisture in oil accelerates oxidation which results in the formation of acids and contributes to the formation of sludge. Over time, the sludge settles on the windings and the inside structures causing transformer cooling to be less efficient and an overall increase in transformer temperature which lowers its efficiency. Therefore, traditional methods of oil inspection inside transformers are not only time consuming and cumbersome, they also contribute directly to increased maintenance costs.   

Solution: The Portalevel MAX INDUSTRIAL will be a safe, efficient and reliable solution to inspect oil levels in transformers non-invasively, typically in transformers that have no means of external oil indication. With the Portalevel MAX Transformer, oil level inspection can be done routinely without opening the lid of the transformer and thus prevent unwanted moisture from being absorbed by the oil which deteriorates the oil.

Results: This practice is capable of prolonging the life span of the transformer oil whilst reducing the cost incurred from frequent oil changes and significant downtime when a fault develops as a result of low oil levels or poor oil conditions.  

Background Issue: High voltage transformer and switch gear units are often designed to be submerged in oil which act as an insulator, making sure any technicians working on the units are not at risk of potentially fatal shocks. As such, it is critical to know that the oil is still present and at a suitable level, before any maintenance or access to these units is undertaken.

Solution and Results: Many companies around the world are beginning to use the Portalevel MAX for checking the oil levels in Transformer & Switch Gear units. Since this equipment can non-invasively check the presence from the outside of the tanks, technicians can operate safely and with confidence.

 The Portalevel MAX INDUSTRIAL is an invaluable tool that has helped customers worldwide reduce their annual maintenance costs and contribute to a more efficient servicing routine.

Know Your Numbers: Mathematics of Gaseous Extinguishing Systems

By starting with the numbers and mathematics of gaseous extinguishing systems, Coltraco are leading the way in the fire industry.

31˚C - CO2’s critical point: the temperature at which CO2 turns totally from liquid to gas.

CO2 is permanently under 720 psi or 49 bar of pressure ie nearly 50 times atmospheric pressure (by comparison a cup of water at sea level exists at 1 bar or 14.5 psi). Its state changes under increased temperatures to one that is neither a liquid nor a gas.

50-55˚C   -  critical points of FM-200® and Novec™1230 (turning from liquid to gas).

Gases under pressure are often effectively considered by the industry as single and passive cylinder columns of solid material from the perspective of their monitoring following installation. Whereas being under pressure and constantly changing under temperature they should be considered as active and dynamic systems requiring constant monitoring. These are not passive systems therefore; they are dynamic ones, and all dynamic systems under pressure need constant monitoring.

14520 - the ISO standard regarding fire systems from installation with regard to room integrity through to maintenance and inspection of contents

ISO 14520-1:2015(E) specifically states in 6.2.4.2 Contents Indication that - Means shall be provided to indicate that each container is correctly charged and in 9.2.1.1 At least annually, or more frequently as required by the authority, all systems shall be thoroughly inspected and tested for proper operation by competent personnel. Under ISO 14520 where gaseous extinguishing systems have to be designed in relation to the discharging agent hold-time (if the room cannot hold the agent because of leaks the agent will disperse and not extinguish the fire) and discharging agent peak pressure (if the pressure is too high for partition walls or suspended ceilings they will be blown apart or damaged and possibly destroying the room integrity). At the design stage of a fire extinguishing system rooms are tested for room integrity by positively pressurising a room and detecting escaping pressure to verify that the room itself into which the gaseous extinguishant discharges on actuation can both hold the agent after its discharge and hold its pressure on actuation. The fire system is then installed and commissioned. However, over the next 10 years no further tests are made on ultrasonic room integrity testing and the cylinders merely hydrostatically tested to ensure they can cope with their design pressure limits. How can one be sure therefore that on actuation the room will hold the discharged agent to extinguish the fire and its partitions and ceilings are capable of withstanding the pressure of the agent on discharge?

5% - loss of agent above which it is deemed unacceptable in liquefied gaseous extinguishing system and thus requires refilling. 10% - loss of pressure above which it is deemed unacceptable in liquefied gaseous extinguishing systems and thus requires refilling

The risks of accidental discharge or leakage is recognised within the regulations.  BS EN ISO 14520 -1:2015(E) reasonably assumes that the execution of its provisions is entrusted to people qualified and experienced in the specification, design, installation, commissioning, testing, approval, inspection, operation and maintenance of systems and equipment, and who can be expected to exercise a duty of care to avoid unnecessary release of extinguishant. The assumptions in the installation, commissioning and maintenance of gaseous extinguishing systems is that they are highly pressurised but risk leaking and discharging. The regulations that sensibly underpin this assumption aim to identify their leak identification at an interval of every 6 months. Cylinders accidentally discharge. CO2 can cause fatalities if it does. 1% of pressure gauges fail and 25% of valves too. Essentially, it is known in regulations that the gaseous systems leak and need to be maintained. Given that the gaseous systems are designed specifically to the individual need of that room, building e.t.c, then a 5% loss of agent may mean that they would not fully extinguish the fire. What if there are also leak sites in the room? The likelihood of the gaseous system effectively extinguishing the fire gets lower and lower.

2.1.1.3 - The paragraph points from Chapter 5 in the IMO SOLAS FSS Code which details how vessels’ fire extinguishing systems should be checked for leaks

A ships Officers & Crew are not qualified to undertake CO2 servicing as it requires the dis-mantling, weighing and re-installation of the complete system which must be done by a licensed organisation when the ship is alongside. The code states that; “means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers.” To implement the IMO SOLAS FSS code, portable liquid level indicators such as Portalevel™ units are used on-board, allowing the crew to meet the code between servicing

1.5mm - the accuracy which Portalevel® and constant monitoring Permalevel® Multiplex can find the liquid level of agent in cylinders to.

26 seconds – The average test time to identify the liquid level in any liquid gaseous cylinder using the Portalevel® Max.
The UL approved Portalevel Max is designed to inspect the content of Fire Suppression System Cylinders of CO2, FM-200™, Novec 1230, FE-13, FE-25, NAF S III, CEA410, Halons and a range of other extinguishing agents. The device is a quick, accurate and efficient method of inspecting cylinder content. Portalevel® MAX builds on Coltraco Limited’s 30 years’ experience in designing, manufacturing and supporting Ultrasonic Liquid Level Equipment.  The unrivalled quality of the Portalevel, have resulted with units operating throughout the world.

0.06mm  -  the size of leak site able to be detected by Portascanner® 520 in Room Integrity.

Assuming 2 metres of water above the leak of this size, the water flowing through the hole will sufficiently fill 4.64 cans of soft drinks per day.

Using ultrasonic technology this the Portascaner® is able not only to pinpoint precise leak locations, but to determine their leak apertures as small as 0.06mm with a tolerance of +/-0.02mm, making it by far the most accurate device for this function. The Portascanner® also provides an interpretation of the seal for desired locations, labelling them either watertight, weather tight or full leakage site as appropriate. The advantages of being able to accurately detect the exact leak locations and size are self-evident when considered alongside the importance of reaching Peak Pressure for clean agent fire suppression to be effective.  The immediate use of the Portascanner® lies in its improvement of the final stage of room integrity testing – the search for leak sites in the case of a leakage excess – for which it can vastly improve accuracy and operational efficiency.

RS232/RS485 - communications capabilities Permalevel® Multiplex offers including dry contacts, 4-20mA relay for constant monitoring of liquid level.

24/7, 365 - continuous monitoring of gaseous systems and the room integrity

Permalevel™ Multiplex, is designed as a fixed 24/7 system to monitor anything from 5 to 700 cylinder level points. It is a modular system and each module will cater for up to 16 level points. The Permalevel™ Multiplex is the first system worldwide that is capable of monitoring the liquid level of critical fire suppression cylinder systems on a constant basis. The unit can be easily installed on new systems or retrofitted to existing systems, and can monitor up to 16 level points simultaneously. The system has a remote display showing the status of each cylinder, as well as the ability to link to remote local alarm or indication method. It can also remote link the status back to any Central Monitoring Station. The Permalevel Multiplex is designed to ensure that fire suppression systems are always fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event that it is required for use. This allows a facility to have complete confidence that they are fully protected.

0.1mm± - The accuracy tolerance of both the Portagauge® 3 and Portagauge® 4 ultrasonic thickness gauges

Metals corrode and pressure gauges stick. Annex F of ISO 14520 specifically guides our industry as to these risks stating every 6 months the following checks and inspections must be performed: 1) externally examine pipework to determine its condition; replace or pressure test and repair as necessary pipework showing corrosion or mechanical damage; 2) check all control valves for correct manual function and automatic valves additionally for correct automatic function; 3) externally examine containers for signs of damage or unauthorized modification, and for damage to system hoses. The quick, simple and hardy Portagauge ™ 3 allows accuracy of ±0.1mm even on corroded, challenging and some plastic surfaces. It utilizes single echo technology which allows the unit to maintain accuracy even on corroded or challenging surfaces. It is ideal for corrosion, rust or condition inspections and is a highly dependable unit. The Portagauge™ 4 is able to ignore surface coatings such as paint. With easy calibration and no zero-ing required, the Portagauge 4 is ideal for effective and efficient thickness gauging applications

5% – Accuracy tolerance of the Portasonic® handheld ultrasonic clamp-on non-invasive flow meter at flow rates over 0.5m/s

There are a number of issues to be considered in regard to maintenance such as corrosion, flow rate and obstructions that may adversely affect the effectiveness of a fire sprinkler system . Portasonic® is easy to use and is proven to reduce maintenance time and costs. It can also be used for testing fire hydrants. The flow is calculated so that there is always enough to control a fire taking into account the size and construction of the building and the goods stored in it or its use. Accurate flow data provides the chance to make energy saving measures by fine tuning the systems. The Portasonic can measure this through self-adapting proprietary signal quality tracking, allowing the system to automatically optimally adapt to the pipe material and flow profile in both directions. The ability to conduct spot checks on the sprinkler system at mandated intervals ensures the full integrity of a sprinkler system.

1% - the accuracy of the agent weight calculated by the Portasteele® through liquid level identified using Portalevel® compared to weights determined by manual weighing methods

The Portasteele® Calculator is an advanced calculator application, that converts the liquid level height of C02, NOVEC™ 1230 and FM-200® liquefied gaseous extinguishant agent readings taken on an ultrasonic non-destructive liquid level indicator device into the agent weight/mass.  Furthermore, the Portasteele® can convert an expected agent weight back to the required liquid level allowing users to anticipate where the level should be.

Integrity is our defining value. Performance is its consequence. Coltraco is experienced and globally renowned.

Gaseous Systems Leak – Test Your Cylinders

To extinguish a fire, ships need:

  • the correct amount of gas in the fire suppression system cylinders to extinguish the fire
  • compartmentation integrity to starve the fire of oxygen
  • pipework integrity to ensure the gas discharges correctly

To ensure vessels sail safely these points must be implemented, meaning:

  • the crew must have the means to test the cylinder content themselves ie liquid level indicator, as the crew is not qualified to traditionally weigh
  • there is a need to educate the crew about fire engineering to protect against risk of CO2 actuation in manned areas and to ensure compartmentation etc

As stated in IMO SOLAS FSS Ch5. 2.1.1.3: “Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers.” Often this is misunderstood, this code specifically states that the crew must test their extinguishing installations in between the periodic inspection, maintenance and certification. Only having the annual inspection by accredited marine servicing companies is not enough – _the crew must take responsibility for their own fire protection. However, what must be noted is that the crew are often not trained or certified to shut-down, dismantle, weigh and re-install the gaseous cylinders. To overcome this, ships need to test their CO2 systems for contents in-between the annual certification checks by marine servicing companies. Using an ultrasonic liquid level indicator is the only way that the crew can safely test their CO2 without disturbing them. Coltraco Ultrasonics designed the Portalevel® handheld ultrasonic liquid level indicators, because radioactive units were being phased out. If shipping companies implemented the IMO SOLAS FSS codes by testing safely and quickly (just 30-60 seconds per cylinder) by using liquid level indicators and marine servicing companies were able to do their work without allowing for time pressures, then marine safety would be far safer.

40 Million Sprinklers Are Fitted Worldwide. How do you monitor yours?

For a business and property owner, protecting against potentially catastrophic results of fire such as life loss, property damage and loss of assets is a common challenge.

Automatic sprinkler systems are used more than any other fixed fire protection system and over 40 million sprinklers are fitted world-wide each year to deal with this problem.

However, if sprinkler systems are not periodically inspected for mechanical deficiencies, proper function, valve actuation, water flow, sprinkler clearances, etc., the system may not be effective during a fire. Corrosion can cause a sprinkler system to fail due to blockages and failed sprinkler heads.

NFPA 258 provides required inspection, testing and maintenance for a sprinkler system.

FM 200 fire suppression system; highly recommended system around the globe

Harms made by the fire blazes are far greater and that is the reason fire smothering operators are expanding the market to profit individuals and to ensure them fire episode. Be that as it may, these fire extinguishing systems are additionally causing harms and one must be more specific while picking any of the fire quenching frameworks as opposed to confronting the harm which cause them to lose a considerable measure of important things. There are number of operators accessible with changing characteristics and properties around the world. Consciousness of each kind of material is vital in light of the fact that for everything there is an alternate sort of operator is requires keeping the fire from spreading.

Among the most recent fire-dousing specialists, the favored one is FM 200 fire suppression system. It is effectively accessible and the properties which make it generally prescribed is that it is a vapid and scentless gas; it is thought to have low impact on the earth as there are some which are thought to be peril for to nature making harm the ozone layer. FM 200 fire suppression systems when used and showered in crisis, it doesn't make any harm the any of the thing. This framework is utilized over the globe as it is calm productive to address the issue and blow the fire in a squint of eye.

These frameworks ought to be observed appropriately and routinely. There level checking is mandatory in light of the fact that on the off chance that it fall then these framework are pointless. They are kept in chambers which are in type of packed gas in condensed frame and they fall with the time. There levels can be checked with the assistance of ultrasonic liquid level indicator which is based on the advanced innovation. They are exceptionally phenomenal pursuers and give results in standard interim. They are exceptionally valuable since they don't require any manual working and thus they are diminishing the quantity of work.

These liquid level indicators are best since they are recording every one of the information in the PC framework. They are additionally having caution framework which will ring up when there is a levels fall. These ultrasonic gadgets are exceptionally helpful and are supporting in numerous different things while giving the precise outcomes and profiting the business. They are effortlessly accessible in the market and can be obtained from online store with great quality.

Ultrasound Explained

One of the sciences being harnessed by innovators in the fire safety sector is that of Ultrasound: i.e. acoustic (sound) energy in the form of waves of high frequency that are above the human audible range. Although the shipping world merely uses it as a tool to gauge thickness, it has seen far more varied use across military, medical and industrial fields. 

Sound is, in itself, vibrations that propagate as a mechanical wave or pressure and transmit through solid, liquid or gaseous mediums. Coltraco is one of a number of companies using these fundamental physical principles to design and manufacture products and systems that can be used by fire engineers and their customer installations. Ultrasound is merely sound beyond our audible range. Dolphins and whales can communicate at sea over long ranges as sound travels more efficiently through liquids than air. We use this principle to identify that difference in a cylinder containing liquefied agent. Consider ones ears as ”the receiver” and ones mouth as the “transmitter”. Sound will arrive at ones ears at different times. The reason though that we hear a unitary sound is that our brain processes it to one. This is what we do by processing the returning ultrasound. In the air bats navigate by airborne ultrasound. We can do the same for contents and room integrity monitoring in the fire industry.

By utilising a sensor which acts as a transceiver, an ultrasonic measuring device is capable of detecting liquid levels within any single-skinned container through transmitting an ultrasonic pulse and analysing the strength of the returned signal to determine the level of contents. As sound behaves differently in air and liquid, so will the strength of the returned signal be different in the liquid allowing us to identify the level of contents accurately. Similarly, leaks can be effectively detected through an ultrasound generator placed in an enclosure and an ultrasound receiver outside of the enclosure to measure the amount of ultrasound that leaks from the seals and cracks which has the potential to affect the ability for a clean agent to extinguish fires due to the retention time it needs upon discharge to function at its best. Taking these collected data and transmitting them wirelessly over TCP/IP, true remote monitoring of your fire suppression systems is possible anywhere around the world.

Coltraco manufacture the portable liquid level indicator Portalevel™ used by fire technicians for the contents checking of CO2, old Halons, FM-200™ and NOVEC™ 1230.

  • Portalevel™ liquid level readings are then converted to agent weight readings via Portasteele™ Calculator – Calculating fire suppression agent weight  the world’s first
  • Constant monitoring of the contents of gaseous systems are now enabled via the 24/7 system Permalevel™ Multiplex

Carnival Cruises chose Coltraco to supply their Fleet with the UL Listed and ABS approved Portalevel® MAX Marine in order to address the issue of the ungoverened space. The Portalevel Max Marine in under 30 seconds using Portalevel® MAX with one person, instead of the traditional 15 minutes with two people labouriously weighing. Using ultrasonic technology - to pinpoint the liquid level of suppressant agent in the cylinders of the fire extinguishing system- testing is made quicker and easier. The Portalevel® MAX Marine is designed primarily for maritime applications where either third party approved service companies or the vessels’ crew themselves inspect large fire suppression systems which can have up to 600 cylinders. The ease of operation in comparison to weighing increases the ability of the servicing/crew to make more regular and more frequent checks, thus improving fire safety management system (SMS) onboard. The ABS Product Design Assessment certification categorises the Portalevel ® Max as a practical and effective unit which complies with international standards.

Need to monitor Protected Space Room Integrity

Coupled to this is, is the danger of a lack Room Integrity testing after the gaseous system has been installed.  As vesselsage or their internal use is changed leak sites develop. If the gas cannot be “held” in the confined space on discharge during a fire event the probability of its suppression diminishes in direct proportion to the size of the leak sites. Clean agents are designed to operate in limited spaces where there is a need for speed of suppression given the asset risk and where the space is occupied by people. They must be easily maintained in-situ, non-flammable and non-toxic. They must comply with NFPA 2001 standards demanding fast discharge in 10 seconds and fire extinguishing within 30 seconds, delivering confidence to the operator that it delivers “best fire safety practise”. 

Compartmentation Integrity – complementing Door Far Testing

It is here that the value of the Portascanner  Watertight Integrity Testing Indicator is evident. This unit is a small, hand-held ultrasonic device featuring dual Decibel & Linear readings in the display and widely used in Shipping, Naval vessels, Submarines and Offshore Oil & Gas Platforms. Moreover, the unit is supported by regional Service Stations in USA, UK, Dubai, India and Singapore. Using ultrasonic technology this device is able not only to pinpoint precise leak locations, but to determine their leak apertures as small as 0.06mm with a tolerance of +/-0.02mm, making it by far the most accurate device for this function. The Portascanner also provides an interpretation of the seal for desired locations, labelling them either watertight, weather tight or full leakage site as appropriate. The advantages of being able to accurately detect the exact leak locations and size are self-evident when considered alongside the importance of reaching Peak Pressure for clean agent fire suppression to be effective. In a case where there is too much leakage in a room (and thus insufficient Hold Time), the Portascanner is an unrivalled ideal for the rapid and accurate identification of these sites so that they can be sealed. It is lightweight, fast and easy to use, allowing leak site detection to increase its operational efficiency and speed to a degree that has never been seen thus far.

It is perfectly positioned to work alongside Door Fan testing in order to meet the total requirements for fire safety regulations and ensure the continuous fire protection of rooms using Clean Agent Fire Suppression systems. As Door Fan Testing has been proven to be a reliable and trusted method of room testing by industry experts, it is expected that its dominance shall continue in the near future. The immediate use of the Portascanner lies in its improvement of the final stage of room integrity testing –  the search for leak sites in the case of a leakage excess –  for which it can vastly improve accuracy and operational efficiency. Portascanner 520 is a hand-held product designed to identify leak-sites in Protected Spaces.

The future is 24/7 constant monitoring.

The main issue is that without continuous monitoring, a leak could still occur at any point in between tests during a journey, and a crew member is still needed for testing. Research is being carried out by enterprises such as Coltraco Ltd. to create the most comprehensive and safe solution using ultrasonic technology.

It was found that a comprehensive, autonomous continuous monitoring system for the watertight integrity of a ship’s cargo hatches, weathertight doors and other seals is possible to be developed. One that is capable of automatically detecting emerging leak sites, alerting officers and crew to the location and severity of the leak site and logging all data by hatch cover for future review. Coltraco is looking to see this technology fully utilised by 2020, as part of a pioneering wider vessel system integration and shore-based data management. It is becoming clear that UT is developing into an integral component of watertight integrity testing for ship hatch covers in particular, and is best positioned to secure the safety of vessels in the shipping Industry. Ultrasonic readings from hatches / doors / MCTs can also be logged and trended over time which helps increase safety and can also be used for insurance companies. There is more work to be done, and the future of UT must be condition-based monitoring of hatch covers, providing continuous monitoring.

A monitoring system is required for the watertight integrity of important seals capable of automatically detecting emerging leak sites, alerting officers to the location and severity of the leak site and logging all the data from hatch cover tester for future review. Continuous monitoring of this kind has the potential to centralise a vessel’s watertight and airtight integrity into a single alarm system. When used on a warship, such a system would also allow the status of the ship to be transmitted for an analysis and response by supporting vessels.

The future of UT is increasingly moving towards constant and even automatic monitoring of the performance of all types of seals, especially critical ones. Furthermore, in the near future, low power ultrasonic generators will allow submarine crews to easily conduct watertight integrity tests without the risk of alerting enemy vessels to their presence by picking up the ultrasonic noise through the hull.

The Smart Ship is a Safe Ship.

Safety Of Life At Sea is the critical code we all wish to see implemented. Beyond saving human lives, we protect the vessel then the cargo. Today we take that further to protecting our marine environment and increasing efficiencies. We understand that the Smart Ship can be interpreted as the fully automated and unmanned vessel, but for Coltraco Ultrasonics the Smart Ship is interpreted as a safe ship and that is our priority. Using ultrasonic technology, the Safeship® is achieved by the increased monitoring of the two main causes for vessel loss: sinking and fire. Using our expertise in ultrasonic technology, Coltraco Ultrasonics achieve the Safeship® through the monitoring of watertight integrity testing and gaseous extinguishing systems, benefitting from the continuing and developing technologies of the Internet of Things (IoT).

Using technology that has come to fruition and also in development, ship owners are able to protect their crew, vessels and cargo with Smart Safeship® technologies.  This paper argues we can better implement the Smart Ship, existing regulations, and strengthen new ones, thanks to more sensor monitoring technologies which will be linked by the Internet of Things (IoT). The application of the Internet of Things and ultrasound allows the Smart Ship to be achieved here and now, with technology that is implementing and exceed regulations. Continuous monitoring solutions benefit the crew; by being easy to operate, quick, accurate and a better than traditional monitoring techniques, meaning the likelihood of their use and thus protection is much higher. Whilst regulations can be said to drive up costs in the short term, their longer-term impact can save time, costs and improve the industry. Those in the shipping industry must strive towards the Safeship®: holistic protection of their fleet.

Meeting obligations

Interviee with CEO Dr Carl Hunter.

“Given both the crew lives and cargo at stake, it seems unfathomable that these systems are not permanently monitored rather certified just once a year, particularly since it is a regulatory obligation to ensure that crew are in a position to check these,” Hunter says. Safety of Life at Sea’s (SOLAS) International Fire Safety Systems (FSS) code states that “means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers”.

It can be argued that the existence of regulation (such as that set by the the IMO and other authorities) guides – and occasionally curbs –  the direction taken by the free market. This then means that the current state of the market, where ‘price is king’ is either due to unwillingness on the part of the regulators to create an environment where safe engineering is rewarded or because the industry itself is unaware of new technology that will help them meet both the spirit and letter of the regulation.

The fact of the matter is that technologies exist right now that can easily and accurately monitor everything from gases under pressure to liquefied contents and corrosion of pipework. The traditional method of using a cylinder pressure gauge (located at the meeting point of valve and neck of a pressurised cylinder) is both obsolete and impractical – especially when cost cutting may result in use of minimally-compliant gauge mechanisms.

Technological answers

Technologies will soon exist that will offer devices that monitor both liquid content and gas pressure safely from the external sides of the cylinder rather than within it. This means that crew will be able to monitor the contents and then calculate the mass/weight of the liquefied extinguishant. By measuring the pressure of the gas on top of the liquefied extinguishant they can can assess the pressure of an Inert gas (which is in an entirely vaporous form) to ensure that the cylinder is primed to perform when needed. 

Having systems that operate transparently will work not just to convince a vessel owner that his asset is in good hands, but also to reassure the crew that their safety is taken seriously by both – their employer and the  marine servicing company.

Its portfolio boasts 11 different model types of Portalevel brand liquid level indicators including Portascanner (which uses ultrasound to test the integrity of confined spaces and can detect leak sites as small as 0.06mm) and Portagauge (which uses ultrasound to test the internal and external corrosion on pipework and cylinder wall thickness to an accuracy of +/-0.1mm). “We can monitor these 24/7 with the fixed, data-logging and autonomous monitoring system, Permalevel Multiplex & Permalevel Single Point,” says Hunter. “Signals from these fixed monitoring sites can be monitored centrally on the bridge and in the ship’s technical office concurrently. We see a day when products and systems will be designed that will monitor gas vapour above the liquid level and inert gases too.”

What protects the crew from fire?

A ship’s gaseous extinguishing system typically comprises between 200 and 600 cylinders each containing 45KG of CO2 under high 720 psi/ 49 bar pressure. (Other suppressant clean agents such as FM-200® and Novec™1230 are becoming more widely used.)

How are we failing to protect the crew with these gaseous extinguishing systems?

Because gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use and this is shown in the regulations that demand their upkeep.

IMO SOLAS & FSS Code Chapter 2.1.1.3 - “Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers.”

Some marine service companies estimate that 20% of a ship’s CO2 cylinders have discharged or partially leaked their contents at some point in their lifetime also know that occasionally marine “servicing companies” unintentionally leave it disabled.

Why is this the case?

Time pressures.

Most marine servicing companies only have 4 hours on a vessel in a port to test up to 600 cylinders. It is known that it takes 15 minutes for a 2 person team to shutdown, dismantle and weigh a single CO2 cylinder, which is equal to 16 cylinders in 4 hours. Yet despite this, every CO2 cylinder on the vessel receives a “tested and certified sticker” and the marine CO2 system is certified and a certificate is issued.
As well as this, any vessel with a gaseous extinguishing system needs to consider 3 factors:

  • Unless compartmentation exists the gas (e.g. CO2) will not be able to concentrate
  • Unless the gaseous contents exists in sufficient designed amount, extinguishing will not occur
  • The pipework and flanges must be tested to be free of corrosion-generated particulates which block the nozzles and must be tested to be able to withstand the shock of gas discharge on actuation

What measures should be taken?

Fire protection on board is not unlike fire protection in buildings: If a fire breaks out and is not quickly brought under control, all that is left is a ruined shell, fit only for the wrecking ball. In turn, in the case of ships, a total write-off. To better protect the cargo on container ships, with a value running into many millions, it makes sense to modernize the on-board facilities for containing and extinguishing fires.”

There is a call to respond to regulations with a rigorous attitude, to go above and beyond, to provide security of life and infrastructure.

Currently, there is a failure to protect the lives of the crew. Ensuring the safety of the crew is not an option, it is a requirement.

What is the solution?

The crew must take responsibility for its own fire protection.

Using an ultrasonic liquid level indicator is the only way that the crew can safely test their CO2 without disturbing them. Coltraco Ultrasonics designed the Portalevel® MAX Marine & Portamarine® ultrasonic liquid level indicators, as radioactive units were being phased out. If shipping companies implemented the IMO SOLAS FSS codes by testing safely and quickly (just 30-60 seconds per cylinder) by using liquid level indicators and marine servicing companies were able to do their work without allowing for time pressures, then vessels would be far safer.

Solutions for the monitoring of the vessels gaseous extinguishing system exist:

  • Portalevel® MAX Marine liquid level indicators used by the crew weekly to test for contents
  • Portasteele® CALCULATOR converts the liquid level readings into a weight measurement, logging the recorded data with easy exporting via email. By reducing time needed for reports, more time can be spent on ensuring the safety of the vessel.
  • Portascanner® WATERTIGHT, watertight integrity test indicators used by the crew to test for compartmentation
  • Portapipe® pipework integrity indicators used to test for pipework obstructions and the Portagauge® thickness gauges for pipework corrosion

Can your business risk to lose $4.5million?

With the size of turbines increasing, the wind industry needs to learn about the importance of fire safety in wind turbines. Fire is the second leading cause of accidents in wind turbines after blade failure. As our reliance grows on wind turbines, keeping them fully operational and at reduced levels of risk becoming more important, and as a result, so does safety management.  10-30% of all loss-of-power-generation incidents in wind power plants are due to fire. Fires in wind turbines not only lead to a loss of business continuity and a negative impact on the company’s reputation but also, most importantly, are a critical safety issue.

With predictions of much taller and more powerful turbines and thus fewer per project, ensuring that the they are in working order is essential, because the larger and fewer the turbines, the more costly they will be to operators in the event of fire damage. Due to the height and location of wind turbines, classic firefighting methods come up against their limits and therefore fire extinguishing systems that use gases such as carbon dioxide, inert gases or clean agents such as FM 200 fire suppression system

and Novec™1230, which are especially appropriate for dealing with fires in electrical systems because they extinguish the fire quickly whilst not damaging the electrical systems or the compartment in which they are being discharged. 

However, it is important to note that such fire extinguishing systems require maintenance to ensure they are fully operational and ready in event of a fire. ISO 14520-1:2015(E) assumes that these systems accidentally discharge and leak. 6.2.4.2 Contents indication: “Means shall be provided to indicate that each container is correctly charged.” Followed by “9.2.1.3 The storage container contents shall be checked at least every six months as follows. a) Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure (adjusted for temperature) of more than 10 %, it shall be refilled or replaced.”

Focused on continued advancement of safety technology, Coltraco have now developed the Permalevel® Multiplex, a fixed fire suppression monitoring system, designed for continuous contents verification. Permalevel® is designed to ensure that fire suppression systems are always fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire. With guaranteed systems operations, adaptability for purpose, 24/7 remote access to the systems status, an uninterruptible power supply (UPS) and remote real-time monitoring, the Permalevel® offers the efficiency that is needed in a wind turbine.

For regular inspection, the Portalevel® MAX is a handheld ultrasonic liquid level indicator, which can service a cylinder in 30 seconds (in contrast to 15 minutes by traditional manual weighing) with accuracy of up to 1.5mm off the true liquid level. Portalevel® MAX builds on Coltraco Ultrasonics’ 30 years’ experience in designing, manufacturing and supporting ultrasonic liquid level indicating equipment, in 108 Countries and numerous market sectors and environments. The development program was born out of the desire to further improve on Coltraco’s existing 8 designs and taking on board feedback and opinions of our customers.

Coltraco Ultrasonics provide smart Firetest® solutions which enable wind turbine owners and operators to improve their fire safety management and reduce the risks to human life, business continuity caused by any downtime and thus minimise risk to reputation by delivering a Safesite®.

How are we failing to protect the crew by maintaining hatch covers?

Wrongly applied and poorly maintained cargo hatch covers and sealing systems increase the risk of cargo becoming damaged by water. The most common wet cargo problems include leaking cross joints, and compression bars, rubber gaskets, hatch coamings, drain channels and cleats in poor condition.

The importance of continually maintaining seal integrity must take a more prominent position in ship maintenance scheduling as demanded by regulations:

SOLAS Reg II-1/11.1  it states that hatches and watertight seals must be regularly tested: “Where a hose test is not practicable [sic] it may be replaced by [sic] an ultrasonic leak test or an equivalent test. In any case a thorough inspection of the watertight bulkheads shall be carried out.”

How have hatch covers been tested traditionally?

Chalk testing is used traditionally for visual inspection of the compression integrity of doors and hatches on vessels that hold the potential for flooding. Chalk is applied evenly around the knife edge, coaming compression bars or panel cross seams of doorways. The door/hatch is then closed and sealed. Once re-opened the rubber gasket which pushes against the knife edge is visually inspected for the chalk line. Any breaks in the chalk line indicate a lack of compression in that area. It must be noted that chalk testing is NOT a leak test, but only provides an indication of potential compression issues

The International Association of Classification Societies states that a chalk test must be followed by a hose test. The hose test is used in conjunction to determine the weather tightness of doors and hatch covers. The spray from a nozzle of 12mm diameter is sprayed from a distance of 1 to 1.5 meters with a water jet pressure of 0.5 ms-1 This test should help identify any leakage from the hatch joints, although the exact location of the leakage sight cannot be pinpointed.

Why are these methods no longer recommended by P&I clubs?

Various drawback come with chalk and hose testing, for instance;

  • The hold is required to be empty as cargo can be damaged by water. This is not always possible and certainly poses more issues once the ship is laden with goods. 
  • The test requires drains to be opened posing a genuine pollution risk. 
  • Two people are required to carry out the test effectively. 
  • Cannot be performed in sub-zero conditions.
  • Water pressure and distance can affect results.
  • Time-consuming.

Both of these tests are time-consuming and sometimes completely impractical. Some circumstances have been highlighted that prevent this test from being conducted such as the hose test if dry cargo is within the hold being tested but these tests conducted at port or in dry dock will never reproduce conditions when the ship is at sea and therefore cannot expect to achieve the same standard. Claims resulting from water damage due to leaking hatch covers still contribute a huge part of the overall loss figures on dry cargo ships. This method is neither accurate nor time effective.

What is the alternative?

Ultrasound.

The Swedish P & I club recommend using Ultrasound. As stated in their 2018 report “A much more effective method is to use an ultrasonic device, which is designed for this purpose and can pinpoint the area which is leaking, and if the compression of the gasket is sufficient. The advantages of using this type of equipment are evident, since ultrasonic tests can be carried out during any stage of the loading without risking cargo damage. The test can also be completed in sub-zero temperatures. The ultrasonic test should be carried out as per the class requirements.” 

Ultrasonic testing is a dramatically more sensitive, accurate and reliable method for cargo hatch cover testing, bulkheads and doors for watertight integrity on all vessels. A multi-directional ultrasound emitter is placed in a hold. The opening being tested is then sealed and the receiver switched on ready to receive any leakage of ultrasound via a set of headphones. An increased reading of ultrasound signal signifies an issue with the integrity of the door/hatch. Further, and closer inspection will allow identification of any specific leakage sight along with the severity. This test will take approximately 10 minutes and requires only one operator. 

Which is the best ultrasonic test kit for hatch cover testing?

Owners, managers, marine surveyors, third party servicing companies and other mariners have pledged their support for the Portascanner® WATERTIGHT for years.
For 3 simple reasons: “it is faster, better, cheaper” than any competitor. But don’t take Coltraco Ultrasonics’ word for it, here are 3 customer testimonials:

We did some transit inspection work on one of our customers vessel using the Portascanner and we are very pleased with your instrument. We are looking forward extending our service offer using it.” – Techsol Marine, Canada

“The fleet was equipped with a unit per Bulk Carrier and the units are and working well, providing the confidence that there will be no problems with water damage claims.” Ship Management Company

“Our PORTASCANNER WATERTIGHT unit performed well during the entire period of use, proved rugged and we feel sure that if it had not required returning for mandatory calibration and certification, the unit would have performed well for many more years to come.” Captain J.F. Holmes, Botrans

The Portascanner® WATERTIGHT is:

  • Faster: designed for ease of use from poorly educated crew up to chief engineer – no need for extensive and expensive training courses, simply read the operating instructions in the kit and away you go
  • Better: most mathematically accurate to 0.06 (+/-0.02mm) to identify leak integrity quickly and easily allowing prompt maintenance if required
  • Cheaper: never beaten on price guarantee from Coltraco Ultrasonics who are used to serving the world’s leading fleets for 30 years

The Portascanner® generator is the most efficient of all on the market. Unlike the old “Hedgehog Generator”, the Portascanner® generator has excellent battery life, is light and small, has magnetic mount, is highly sensitive and uses smart pinpoint technology to direct ultrasound to the seals during testing.

Coltraco Ultrasonics’ mission delivering Safeship® solutions to improve safety of life, assets and vessels at sea. They do  by manufacturing high quality British instrumentation, supplied to over 100 countries worldwide, since 1987. Coltraco Ultrasonics focus on benefitting the crew; designing innovative ultrasonic solutions which the crew will be happy to use by being easy to operate, quick, accurate and a better method to traditional techniques. Thus increasing the likelihood of tests being regularly conducted, in line with regulations and even going above and beyond for more frequent testing. By so doing, the crew will be creating a safer ship.

CASE STUDY Fire & Explosion:

WHO? NRG Energy

WHERE? The Morgan Town Plant is a coal powered power station based in Maryland. NRG own the USA’s largest and more diverse power generation competitive portfolio. NRG are dedicated to smart and reliable energy sourcing, and emission reductions although coal is a significant part of the electricity generation.

WHAT? Fires and explosions pose a constant threat to the safety of miners and to the productive capacity of mines. Mine fires and explosions traditionally have ranked among the most devastating industrial disasters. The prevention and control of fire and explosion in mines is fundamental. On a mine site, fire hazards may occur in and around process plants, underground conveyors, static and mobile plants, draglines, workshops, substations, monitored control rooms and switch rooms. All mines have highly expensive and mission critical equipment that typically operate day and night under extremely hostile conditions, in vast, remote and difficult to access environments, especially on underground equipment.

Gaseous fire suppression systems are the preferred systems installed to protect the high value asset and safeguard operators and processes so as to guarantee business continuity.

WHY? Gaseous extinguishing systems are pressurised, and therefore exist in a dynamic state i.e. they can leak. As supported by the BS EN ISO 14520 regulation, if clean agent cylinders leak beyond 5% of contents or 10% of pressure they will not extinguish a fire, as they will be below their design concentration.  As the “golden standard” of clean agent systems, BS EN ISO 14520 highlights the asset owner’s responsibility to check that the clean agents contents exist; that the protected space can be sealed; that the pipework used to discharge the clean agents are clear of particulates that can clog up the nozzles which reduces the amount of clean agent to the point where it cannot operate in the event of a fire.
HOW? After witnessing fire service experts undertaking ultrasonic liquid level indication in just minutes, NRG Energy were keen to change from their previous method of weighing which took over 15 minutes. The Portalevel® Max is an example of the technologically advanced techniques that the company are implementing to lead the way in safe and sustainable coal sourcing.  Portalevel® MAX is a handheld ultrasonic liquid level indicator to inspect CO2, clean agents and more liquefied gaseous agents, by one person in just 30 seconds as a safety critical asset, the Morgan Town Plant saw the necessity in investing into their fire safety.

Protect tankers from the risk of explosion 

Addressing fire in tankers is critical, especially when all owners and managers are seeking to reduce risk, cut costs and surge on safety. The safety of tankers is integral for the continuation of their business success. Catastrophic risks to human life, vessel, reputation and revenue all result from a fire event onboard. One simple step towards improving fire safety onboard is ensuring all equipment is intrinsically safe approved, to protect the crew against the risk of explosion. 

The risk of explosion on tankers means that technology inspecting the fixed fire suppression systems must be designed for the atmospheres on tankers. LNG is only dangerous when it meets an ignition source. The International Maritime Risk Rating Agency (IMRRA) placed 12.5% of tankers it assessed in 2017 into the higher risk category for their fire safety. 

SPECIFIC AREAS OF RISK

The engine room, motor rooms and cargo compressor rooms on tankers carrying LNG & LPG are often protected by CO2 fire suppression systems. Fully operative fire systems on an offshore platform is paramount and demanded by ISO 14520 and PFEER codes. Gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use, shown in the regulations that demand their upkeep e.g. IMO SOLAS FSS Ch5. 2.1.1.3. The systems are pressurised approximately 50 bars, significantly higher than a standard cup of water, which is just 1bar. It’s accepted that these systems are not passive but dynamic, thus requiring monitoring.

SERIOUS INCIDENTS

Serious cases of tanker fires and risks have been reported in the past years. In March 2017 there was an explosion on a Chinese Tanker, in which 3 crew members went missing and serious damage to the vessel was caused.  One of the most tragic incidents of 2018 was the Sanchi oil tanker explosion, on 6 January 2018. After the explosion on the tanker, tragically 31 crew members lost their lives. The Sanchi oil tanker was carrying 136,000 tonnes of natural gas condensate, and the estimate financial damage of the sinking of the vessel is estimated at $110 million.

 TRADITION VS TECHNOLOGY 

For the gaseous systems, the traditional method requires turning the system off, dismantling and manually weighing each cylinder on industrial scales. Routine maintenance is liable to be overlooked because the crew is unqualified to test or insufficient attention is given by the owner of the system. It’s neglected to the peril of the lives of occupants of the vessel and at the risk of crippling financial and reputational loss to the tanker.
Ultrasound should be harnessed by innovators in the safety of offshore platforms.  By utilising a sensor which acts as a transceiver, an ultrasonic liquid level indicator is capable of detecting liquid levels within any single-skinned container through transmitting an ultrasonic pulse and analysing the strength of the returned signal to determine the level of contents.  Importantly, due to the risk of explosion on the oil and gas tankers, ultrasonic liquid level indicators used on board to ensure fire safety, must be Intrinsically Safe. 

APPROVE THE APPROVAL METHODS

Intrinsically Safe is a design technique applied to electrical equipment and wiring for hazardous locations. The technique is based on limiting energy, electrical and thermal, to a level below that required to ignite a specific hazardous atmospheric mixture. 

LEADING OPERATORS LEAD ON FIRE SAFETY

At the request of Shell and similar Tanker Operators, Coltraco Ultrasonics have designed an Intrinsically Safe, ATEX Zone 1 Approved, ultrasonic liquid level indicator which offers unparalleled accuracy, speed and ease of use.  Using innovative methods of inspecting leaking cylinders with ultrasonics, enables identification in under 30 seconds using Portalevel® Intrinsically Safe with one person, instead of the traditional 15 minutes, with two people laboriously weighing. Using ultrasonic technology - to pinpoint the liquid level of suppressant agent in the cylinders of the extinguishing system- testing is quicker and easier.

Ensuring that the fire safety systems on board the gas tankers are operational, via smart ultrasonic technology, designed specifically for explosive atmospheres, is essential for protecting lives, the vessel and the cargo.

CASE STUDY: Corrosion in Metal Work

WHO? Vales Point Power Station

WHERE? Delta, Australia. The coal fired power station is at the southern end of lake Macquarie. This power station was built in the 1960’s as a four-unit station, but now operates two 660 MW generating units. The power station is owned and operated by Power International, with the capacity of around 1,320 megawatts, providing 24 hours of around the clock electricity.

WHAT? Corrosion in power plants leads to costly repairs, prolonged maintenance, material losses, poor performance and, if left untreated, failure. In power plants, corrosion is the primary factor leading to costly and critical downtimes. The water-steam circuits in fossil and nuclear power plants are inherently prone to corrosion, as metal components are constantly in contact with water. When corrosion affects systems carrying steam or hot water—such as pipes—material or welds may fail, causing bodily injury or death. Water, steel and dissolved oxygen within boiler units causes boiler tubes to oxidize and corrode. The corrosion forms grooves within the tubes that lead to cracks and boiler failures. Corrosion can account for up to 75 percent of a plant’s arrest time during maintenance and up to 54 percent of production costs.

HOW? To protect against the threat of corrosion, Vales Point Power Station bought a Portagauge® for testing normal structure and stainless steel, so that they could monitor corrosion rates. The Portagauge® 3 is a single-echo portable ultrasonic thickness gauge. The quick, simple and hardy Portagauge® 3 allows accuracy of ±0.1mm even on corroded, challenging and some plastic surfaces. With a 50 hour battery life, measuring thickness ranges between 1.5mm to 99.9mm and a variety of verified testing materials such as steel, quartz and glass PVC, the Portagauge® 3 provides the great amount versatility needed to suit a diversity of safety needs. The handheld highly dependable unit is ideal for a wide range of industrial applications such as fire cylinders, bulk heads, pipework, chemical equipment and oil storage tanks.

What risk does fire pose to the crew onboard vessels?

Lives are at stake. This is unacceptable.

Tragically in March 2018, 5 people lost their lives in the Maersk Honam fire. Financially, the damage from the fire will be the biggest on record, running into hundreds of millions of dollars. Disappointingly, this was not an unusual event. In container vessels alone, the past decade has seen a number of serious fires including MSC Flaminia in July 2012 causing up to $280 million of liability, Eugen Maersk in June 2013, APL Austria in February 2017 and MSC Daniela in April 2017. In July 2018, the merchant vessel SSL Kolkata sank due to a fire than ran for 3 weeks. From SSL Kolkata A number of containers already went into water and are floating in the area, endangering shipping.

What protects the crew from fire?

A ship’s gaseous extinguishing system typically comprises between 200 and 600 cylinders each containing 45KG of CO2 under high 720 psi/ 49 bar pressure. (Other suppressant clean agents such as FM-200® and Novec™1230 are becoming more widely used.)

How are we failing to protect the crew with these gaseous extinguishing systems?

Because gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use and this is shown in the regulations that demand their upkeep.

IMO SOLAS & FSS Code Chapter 2.1.1.3 - “Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers.”

Some marine service companies estimate that 20% of a ship’s CO2 cylinders have discharged or partially leaked their contents at some point in their lifetime also know that occasionally marine “servicing companies” unintentionally leave it disabled.

What measures should be taken?

Fire protection on board is not unlike fire protection in buildings: If a fire breaks out and is not quickly brought under control, all that is left is a ruined shell, fit only for the wrecking ball. In turn, in the case of ships, a total write-off. To better protect the cargo on container ships, with a value running into many millions, it makes sense to modernize the on-board facilities for containing and extinguishing fires.”

  • Portapipe® pipework integrity indicators used to test for pipework obstructions and the Portagauge® thickness gauges for pipework corrosion

CASE STUDY : Oxygen Reduction System in a Data Centre

WHERE? Oxygen Reduction System, England

WHAT? A data centre is a facility that stores, manages and disseminates data.  Data centres are now supporting a variety of heavy industries such as mines.

WHY? Oxygen Reduction system works by taking Nitrogen from the air outdoors and pumping this into the room consistently in order to suppress oxygen levels, down to the level where combustion can no longer occur. To ensure the system works safely and efficiently, ultrasonic room integrity tester is of utmost important for two reasons: (1) A properly sealed room will contain the Nitrogen for a longer period of time, therefore putting less work on the air compressor in order to save energy. (2) If Nitrogen starts to leak from the Server Room, there are safety concerns over where this Nitrogen would leak to as it has the potential to harm occupants in other rooms if the Nitrogen leaks into their room and the oxygen levels were unmonitored.

HOW? Several areas were tested with an ultrasonic room integrity tester where leakage was probable and the readings were noted on the drawings. These were the doors, vents, cable penetrations and also sections of the wall where gaps were visible. The ultrasonic room integrity tester identified the main source of leaks for the room, the doors, where full readings were clearly detected. Multiple air vents in the room were also improperly sealed and some leakage was found into the external room. Cable penetrations leading to the area outside the Server Room were also found to be leaking. Once the required maintenance was conducted and assuming no changes were made to the room, it is safe to assume that the room retains its integrity, thus comply and exceed current ISO 14520 regulations requiring periodic inspections of room integrity whereby visual inspection is usually specified and is not sufficient.

WHAT? The most suitable way to address periodic inspections is through the use of ultrasound. The Portascanner® 520 uses ultrasonic technology to not only pinpoint precise leak locations, but to determine their leak apertures as small as 0.06mm with a tolerance of +/-0.02mm, making it by far the most accurate device for this function. Portascanner® 520 also provides interpretation of the fire resistance of the desired locations, labelling them either airtight or calculates the overall leakage of the room. The advantages of being able to accurately detect the exact leak locations and size are self-evident when considered alongside the resistance to collapse and transfer of excessive heat. In a case where there is too much leakage in a room, the Portascanner® 520 is an unrivalled ideal for the rapid and accurate identification of these sites so that they can be sealed. It is lightweight, fast and easy to use, allowing leak site detection to increase its operational efficiency and speed to a degree that has never been seen thus far in the Fire Industry.

ACT NOW: Nuclear Power Plants Are Safety Critical

Continuous improvements and maintenance are required of the fire safety systems at nuclear power plants due to the safety critical nature of the site.  Incidents in nuclear power plants around the world have continued to demonstrate the vulnerability of safety systems to fire and its effects. The potential danger from an accident at a nuclear power plant is exposure to radiation to the people in the vicinity of the plume from the cloud and particles deposited on the ground, inhalation of radioactive materials and ingestion of radioactive materials. It is for this reason that the safety demands of the Atomic Energy Authority must be met.

The International Atomic Energy Authority state clearly in the Fire Safety in the Operation of Nuclear Power Plants standards that the effects of a single failure in fire safety systems, such as a system not performing its required function, can be detrimental. One example of this is the Chernobyl disaster a catastrophic nuclear accident which cost approximately 18 billion roubles and had a huge human impact. In this disaster a  combination of inherent reactor design flaws, together with the reactor operators arranging the core in a manner contrary to the checklist for the test, eventually resulted in uncontrolled reaction conditions that flashed water into steam generating a destructive steam explosion and a subsequent open-air graphite fire.  This fire produced considerable updrafts for about 9 days, that lofted plumes of fission products into the atmosphere, with the estimated radioactive inventory that was released during this very hot fire phase, approximately equal in magnitude to the airborne fission products released in the initial destructive explosion. Over thirty years later and investment into the site is still required, with Flamgard Calidair providing fire shut off dampers to the Chernobyl, as part of an €1.5 billion multinational engineering project. With fires at nuclear power plants still occurring, such as the 2017 power plant explosion at Flamanville, deemed “very serious” by industry experts, the call for advanced technology is of most importance. A significant technical issue led to a blast in the turbine hall in the unit, although there was no radioactive leak, a thorough investigation is being conducted into the concerning event.

Faced with this problem, a leading UK Nuclear family approached Coltraco Ultrasonics in 2003 and commissioned the first Permalevel™. Focused on continued advancement of safety technology, Coltraco have now developed the Permalevel™ Multiplex, a fixed fire suppression monitoring device, designed for permanent contents verification. The Permalevel  Multiplex™    is  designed  to  ensure  that fire  suppression  systems  are  always  fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire at a nuclear power plant. The application of the Permalevel™ reaches further, with customers using this equipment in alternate specialist and confidential manners to ensure safety in the station. With guaranteed systems operations, adaptability for purpose, 24/7 remote access to the systems status, an interruptible power supply and remote real-time monitoring, the Permalevel offers the efficiency that is now a requirement at nuclear energy sites.

Case study 4: Transformer oil levels in a copper, lead, silver, zinc and gold mine

WHERE? Gold Mine, Australia

WHAT? Transformers are used in electric power transmission and distributions and are devices that transfer electric power at different voltage levels. The main components within the transformers are the core and windings which are oil immersed. An oil conservator and Buchholz relay are also commonly found to monitor oil levels. Their combined function accommodates expansion and contraction of the oil in the main tank due to temperature changes or fault and also to provide audible alarms when the oil level falls below the minimum due to any leakages.

WHY? As transformers age, they become more likely to lose internal oil. It is important for oil levels in the transformer main tanks to be full, as they act as an insulator and allows the transformers to function efficiently. For transformers that are not fitted with an oil conservator or Buchholz relay, few means of ultrasonic oil level indicator inspection exist and traditional methods include inspection by opening the lid of the transformer.  When the lid is opened, the insulating oil is exposed to the moisture in the atmosphere and will increase the rate of oil deterioration causing the life of insulating oil to shorten. Shortened life spans lead not only to more frequent oil changes, but also significant downtime to the system when an oil change is conducted. Moisture in oil accelerates oxidation which results in the formation of acids and contributes to the formation of sludge. Over time, the sludge settles on the windings and the inside structures causing transformer cooling to be less efficient and an overall increase in transformer temperature which lowers its efficiency. Therefore, traditional methods of oil inspection inside transformers are not only time consuming and cumbersome, they also contribute directly to increased maintenance costs.

HOW? The Portalevel® MAX will be a safe, efficient and reliable solution to inspect oil levels in transformers non-invasively, typically in transformers that have no means of external oil indication. With the Portalevel® MAX, oil level inspection can be done routinely without opening the lid of the transformer and thus prevent unwanted moisture from being absorbed by the oil which deteriorates the oil. This practice is capable of prolonging the life span of the transformer oil whilst reducing the cost incurred from frequent oil changes and significant down time when a fault develops as a result of low oil levels or poor oil conditions.  

Industrial Application Case Study: Portalevel® MAX INDUSTRIAL testing Ammonia in Aerospace Component Factory

The UK aerospace industry is the second biggest in the world, with sales in the sector of £31.1billion last year. The aerospace industry is widely seen as the instigator of technology change in engineering disciplines. Within the bounds of manufacturing, the aerospace industry is the important testbed for developments in automation, assembly and inspection. The developments in the engineering of aerospace components often have implications for many other engineering sectors. Coltraco Ultrasonics received a request from an aerospace component manufacturer for an engineering solution for their manufacturing process.

A manufacturer of high end components for Aerospace and other high end engineering based in Wolverhampton, approached Coltraco for assistance with its monitoring of ammonia. The facilities manager met with Coltraco at a show in Birmingham, weeks prior. The facility runs 24/7, 265 days a year and is the size of around 2-3 football pitches. The facility is concerned mainly in manufacturing high end actuators that are installed on a range of civil and defence systems. Actuators are integral parts of modern engineering and their production is essential. The customer uses ammonia in a nitrating process in which ammonia is applied to heated metal, infusing the metal with the Nitrogen. This can have beneficial outcomes such as making the metal infuse with Nitrogen to make it harder, tougher and with higher melting temperatures. The factory asked Coltraco for a solution with its monitoring of the contents within the ammonia cylinders. This is specifically significant because if improperly managed, ammonia may threaten the safety of workers. To check that the ammonia cylinders had enough contents for a run, the manufacturer had been manually weighing the cylinders. However, manually weighing cylinders is inefficient, time consuming, risks damaging the system and injuring the personnel conducting the laborious test. This method also has been shown to incur waste which was costly to the manufacturer.

Coltraco presented an innovative non-invasive, accurate method that is quicker, much easier for the operator to test and thus, saves money. After a formal assessment by a Coltraco Engineer, the Portalevel® MAX  INDUSTRIAL was found effective in accurately and quickly identifying the liquid level indicator within the ammonia cylinders. Portalevel® MAX INDUSTRIAL allowed for more efficient operations and reduced waste by ensuring partially empty cylinders were not returned to the gas supplier. Coltraco offer comprehensive customer service and therefore designed an in-house testing and recording process that was compatible with the manufacturers current monitoring processes.

The Portalevel® MAX INDUSTRIAL builds on Coltraco Ultrasonics’ 30 years’ experience in designing, manufacturing and supporting ultrasonic liquid level indicating equipment, in 108 Countries and numerous market sectors and environments. The development program was born out of the desire to further improve on Coltraco’s existing 8 designs and taking on board feedback and opinions of our customers.

The trial and implementation stimulated interested in developing an Ammonia Portasteele® Calculator program to allow accurate conversion of the liquid level to agent mass/weight. The Portasteele® is an advanced calculator application, that currently converts the liquid level height of C02, NOVEC™ 1230 and FM-200® liquefied gaseous extinguishant agent readings taken on an ultrasonic non-destructive liquid level indicator device into the agent weight/mass. The Portasteele® offers unparalleled efficiency, ease of maintenance and simple training. This advanced technology is supplied on a stand-alone rugged hand-held 7” touch screen tablet which makes these advanced calculations in real time. Data is stored on the Calculator so the crew or service technician are able to easily send servicing reports back to the shore based managers or directly to customers, without having to manually upload the results onto a computer. Furthermore, the Portasteele® can convert an expected substance weight back to the required liquid level allowing users to anticipate where the level should be. The adaptability of Coltraco’s technology allows programs to suit the requirements of their customers purpose.
