Moreover, these devices are continuously being upgraded in regards to the advanced machinery requirement. I have enlisted three major advantages of possessing liquid level indicator for fire extinguishing system you possess such as FM 200 or NOVEC 1230 fire suppression system:

  • The response of ultrasonic sensor does not dependent upon the optical reflectivity and surface color of the object such as the sensing of the brown pottery plate, clear glass plate, a shiny aluminum plate and a white plastic plate is the same.
  • With digital outputs (On/Off) of ultrasonic sensors, they possess accuracy for excellent sensing repetition. Spontaneous ignorance of background objects is possible at major scale even at long sensing distances due to relatively low switching hysteresis.
  • Analog ultrasonic sensors respond linear with distance. With the integration of LED Display, the calculations are displayed with visual indication of the targeted distance. Moreover, this feature of visual or audible inferences helps ultrasonic sensors ideal for linear motion monitoring level monitoring applications.

Case Study related to Engine Room Fire - 2009

Fires on board ships can be devastating, to crew, vessel and cargo. Fire safety standards on board cannot afford to slip. At sea, fire poses one of the biggest threats to ships. Sailing alone and at sea throughout the year and without the ability to call upon the emergency services as a land-based asset might.

The financial effects from onboard engine room fires can run into millions of dollars. Often, after an engine room fire, a ship can rarely proceed under its own power leading to salvage, repairs, downtime and cancellations, all highly costly. Not just financially, but engine room fires can be detrimental to the integrity of a shipping company when the life of the passengers and crew are threatened by a fire. To avoid such situation, it is always suggested to have ultrasonic level indicator on board.

Case study: Engine Room Fire 2009

Here are the facts of this case study:

  • 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.

Could you afford for this crippling financial, physical and reputational damage to happen to your crew and vessel? The correct answer for any ship owner, ship manager and P&I club is “No.”

“All aboard”: Fire safety onboard has to be taken up by us all across the industry

The UK P&I Club recommend that the high risk threat of engine room fires is recognised and that ship’s crew pay particular attention to training and the care, maintenance and correct operation of all fire fighting equipment. The issue goes further as the lack of knowledge of how to effectively control a fire has created difficulty in the past.

  • In one case, firefighting attempts were hindered by the ineffectiveness of the fire smothering system because of a lack of understanding of its correct method of deployment and lack of proper maintenance.
  • In another occasion, a Chief Engineer did not operate the CO2 system release mechanism correctly and, as a result, only one cylinder (of 43) was discharged which had a negligible effect on the fire. It is possible that he released a cylinder from the main bank of cylinders instead of a pilot cylinder in the mistaken belief that this would trigger the release of the requisite number of cylinders.

In other cases, it was found that the filter cover bolts were improperly tightened and there was a lack of proper inspection routines

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. To avoid such situation, it is suggested to have ultrasonic leak detector onboard.

How to deal with the Ungoverned Space?

It could only be possible the way it is done by Coltraco Ultrasonics. Simplyput, the ‘ungoverned space’ is the area in the fire industry where either the regulations or the protecting systems of the critical infrastructure are not effectively providing consistent and reliable safety.

Coltraco repeatedly push for this life-threatening issue to be dealt with, with specific regard to loss of contents in fixed fire extinguishing systems. After continued efforts to make the ‘ungoverned space’ in the fire industry heard, understood and taken action upon, the problem is starting to be recognised by some, but not all. This haphazard approach is dangerous and often unknown to the users of the infrastructure. The ungoverned space in the fire industry must end now. You might have heard of it but now it is time to do something about it.

Gaseous extinguishing systems protect urgently important infrastructure against special hazards, fundamental for the safeguarding of critical facilities. Although many in the fire industry work towards meeting better standards, in their experience, Coltraco have numerous concerning anecdotes of non-compliance:

Systems portrayed and installed by contractors as Novec 1230 gas suppression system but filled with sand or water

  • Room integrity testing with questionable results and with the room integrity remaining un-monitored after testing
  • Liquefied extinguishants being confused by installers with Inert gas systems

Coupled with these anecdotes, currently the regulations are not extensive enough to deal with the risks presented in gaseous systems. The regulations explain that 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.

b) Non-liquefied gases: for inert gas agents, pressure is an indication of agent quantity. If a container shows a loss of agent quantity or a loss of pressure (adjusted for temperature) of more than 5 %, it shall be refilled or replaced. 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 etc., a 5% loss of agent may mean that they would not fully extinguish the fire.

Can one annual check account for the probability of discharge and leakage for the other 364 days of the year between certification checks? No.

The neglect of continuous monitoring of the fundamental protection provided by the gaseous extinguishing systems is to the peril of the lives of occupants of the premises and at the risk of crippling financial and reputational loss to the facility comprising the critical infrastructure.

The examples of where continuous monitoring is essential are many, extensive and varied. If you protect critical infrastructure, then this article applies to you.

However to exemplify the integral nature of continuous monitoring; 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. 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. With fires at nuclear power plants still occurring, such as the technical issue which led to a blast at the 2017 power plant at Flamanville, deemed “very serious” by industry experts, the call for advanced technology is of most importance.

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 for encompassing protection. 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.

There is no use in waiting or denying the problem, continuous monitoring and Safesite technologies must be adopted now. Technological development is inevitable and that can’t wait for regulations any longer. We will not stop until the ungoverned space is fully recognised and dealt with. There is no room for the industry to fall back into old habits. The ungoverned space must be recognised, the science is clear and it shows that the risk to people and infrastructure is real and high. Constant monitoring of gaseous extinguishing systems and must be implemented, people’s lives depend upon it.

Think again. Are you being passive toward active fire protection? If you are, we are here to help you ensure critical safety.

Guideline to Maintain by Running a Cargo Hatch Cover for Dry Ship

What is the Usage of Hatch Cover?

Cargoes and products compartments are managed with specific hatch covers to keep the contact of freight with external environment such as air, dampness, climate and water. Another imperative duty of hatch cover is to keep up the watertight integrity by not permitting any entrance of water or external component inside the compartments of cargo and cause any damage to the steadiness of the ship by unbalancing. Coltraco have a smart solution of ultrasonic hatch cover testing.

Maintenance Requirement for Hatch Covers

Hatch covers of cargo holders are by and large produced using high flexible steel or lightweight steel. They are fixed over a steel bar of the specific cargo hold with elastic pressing entrenched in the middle of them to keep away from water entrance or any other component. A particular routine support to be functioned by responsible officer from the crew on ship is highly suggested, which must majorly includes:

  • Hatch cover testing for any splits, corrosions, breakage and material issues
  • Keep tops tidy of hatch covers and all waste openings to be kept clear
  • Keep hauling wire, rollers, chains, cleats and wedges in operational condition round the clock
  • Look for any missing gasket or broken and supplant it quickly whereas the length of restored gasket must be least 1 m
  • Before restoring elastic gasket, check and amend steel to steel blame
  • Gasket elastic to be of endorsed sort by class
  • Do not forget to grease or oil all the moving parts
  • Check for any pressure driven framework spillage if cover is functioned by oil
  • Oil test to be performed for water driven system
  • Call surveyor after any significant repair in the cover and its concerned areas

Significance of Hatch Cover Testing

It is really important to possess hatch cover tester to carry out the test before setting off for the journey. This test allows you to increase your efficiency and gain the trust of clients for further reliability and business.

Importance of Gaseous Fixed Fire Extinguishing Systems

The International Maritime Risk Rating Agency (IMRRA) has ranked fire safety as the leading tanker deficiency seen by PortState Control for the first six months of the year. In March 2017, there were 152 cases of fire reported. The IMMRA placed 12.5% of tankers it assessed in January 2017 into the higher risk category – a six-month high.

Serious cases of tanker fires and risks have been reported in the past year. In September 2016 a Pemex oil tanker had a serious fire in the Gulf of Mexico, on which it was carrying 80,000 barrels of diesel, 71,000 of gasoline and 16,000 barrels of desulfurized gasoline. In March 2017, there was an explosion on a Chinese Tanker, in which 3 crewmembers went missing and serious damage to the vessel was caused. Even as recently as seven month of this year, fire safety is still being neglected, with the crew of the tanker MT IBA reporting empty fire extinguishers (despite transporting crude oil) and leaking life boat’s hydraulic system with no means of testing.

Security of life at sea primarily, then of cargo and asset is critical at sea. Fire safety is especially so, yet even in 2017, gaseous fixed fire extinguishing systems are often overlooked and misunderstood at all levels: owners, managers, chief engineers and crew. The reality is that gaseous systems are checked for contents annually because they are pressurised 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. So, being one of the top leaders, Coltraco suggest you to possess ultrasonic liquid level indicator on board to avoid loss at any cost.

What is a typical ships’ extinguishing system?

In terms of ships’ extinguishing systems, there exist two broad categories: sprinkler systems and gas systems such as CO2 & Marine CO2 Systems. While the former can suffer leakage but the latter can cause catastrophic effect given the high physical pressures. An average ship’s CO2 system comprises between 200 and 600 cylinders each containing 45KG of CO2 under high 720 psi/ 49 bar pressure. One of the highest probabilities of discharge occurs during their maintenance. 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.

Although random checks may be suitable in some sectors, it is worth remembering that because the normal design concentration of CO2 of 34-72v/v % is above the nearly immediate acute lethality level, these systems have an extremely narrow safety margin. As these systems work through oxygen dilution rather than the chemical disruption of the catalytic combustion chain (which is the case with other clean agents), insufficient CO2 levels during an emergency may allow a situation to spiral out of hand. Gaseous extinguishing systems protect urgently important infrastructure against special hazards, fundamental for the safeguarding of critical facilities. Yet, 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. Make sure, you invest a bit more on ultrasonic monitoring system such as liquid level indicator to avoid losing such major content of liquefied gas in cylinders.

With fewer, even lower-skilled crew and greater dependence on autonomous machinery, the dependence on fire systems being checked from shore, let alone on the ship in person, will only become greater. Manual weighing is not only labourious, but also dangerous to the crew conducting the servicing. Numerous accounts of incidents have been reported related to manual weighing, but two of the most significant are the injury to 22 US Marines when a halon-containing fire extinguisher went off in 2015, California and the death of 20 people in an accident on a Russian nuclear submarine when a halon extinguishing system was activated by mistake.
Without the means to manually check and with the threat to the crew, constant and remote monitoring becomes vital. It can be argued that the existence of regulation (such as that set by 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.

Ultrasonic Technology is the Solution

Innovative ultrasonic technology enables shore-based operators to monitor agent contents and combine this data into remote diagnostics to alert them when CO2 or clean agent contents have leaked. Advantageous to managers, owners and P&I Clubs who can be provided with data-driven reports for when issues have arisen in order to swiftly resolve them. Advancing ISO14520 & IMO-SOLAS compliance, constantly monitoring liquefied/non-liquefied gaseous extinguishing systems and room integrity. One of the sciences being harnessed by innovators in the fire safety sector is that of Ultrasound. This acoustic (sound) energy releases 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. 

Being so advanced, this technology have increased the percentage of accuracy of data hence if installed in form of system, it can keep on updating the data. Keeping a record on such scale, it is easy to compare and check for the leaks in cylinders that are consistently losing component stored in it.

GASEOUS CYLINDERS LEAK

Leakage of fire suppression agents from gaseous extinguishing systems remains an ongoing and complex problem. Coltraco Ultrasonics has smart Safesite® solutions to identify leakage.

Offshore oil and gas companies are still haunted by the blaze and explosion that destroyed the Piper Alpha oil production platform in July 1988, causing the deaths of more than 160 personnel aboard the structure – a tragedy that resulted in some much-welcomed ‘toughening up’ of offshore safety requirements.

All the same, fire-related incidents still occur aboard many offshore assets, putting the burden on owners and operators to ensure that safety standards do not slip. A solution to this is Coltraco’s ultrasonic level indicator, varying from business to business. This burden becomes more onerous when one considers that the majority of offshore companies are scaling back their budgets at present, as well as warm-stacking and cold-stacking some of their most valuable vessels and rigs.

However, companies have a duty to ensure the protection of personnel, as well as a natural incentive to safeguard some of the most expensive assets to be stationed at sea – as well as their own reputations – and fire safety is a factor that simply cannot be neglected. This is not purely a problem for the offshore sector but a study conducted by the Finnish Transport Safety Agency has revealed that, between 2004 and 2010, 800 fires were logged in European waters, approximately 10% of which were classed as ‘serious’ and 25% of which required external assistance to successfully extinguish.

Agent leakage

While keeping this in mind it should never be ignored how destructive the fire can be when the fire suppressing cylinders are either partially or fully empty. It is always recommended to have ultrasonic leak detector on board to avoid running out of fire extinguishing agent on time of emergency. Reviewing the scenario, CEO – Carl Hunter remarked this situation which is commonly faced in following words;

 “Anywhere between one-in-ten to one-in-five cylinders, when inspected, have been found to be partially or fully empty. We hear about on-board fires and vessels reporting that the extinguishing installations ‘failed’ to put out the blaze – but failure would have been impossible had these installations been checked to ensure they were full.”

Unfortunately, it’s not uncommon for gaseous extinguishing agent to leak from these cylinders. “This is to be expected when such fire-fighting equipment is stored on land, let alone aboard a vessel for 365 days a year,” says Hunter. In an offshore environment, fluctuations in temperature (especially if an offshore asset is transferred between climes as disparate as those of the North Sea and offshore Brazil) and structural stress can acerbate damage of the cylinders’ seals and cause accidental discharge of the extinguishing agent.

“Gaseous extinguishing systems are highly pressurised. The risk of leaking and discharging is accepted as part of their use in the regulations that demand their upkeep.”

- Hunter

The result? A depleted cylinder, containing only half of its allocated agent, runs out of the substance before the fire is properly suppressed. Subsequently, the fire rages on, destroys the area and possibly spreads to other sections of the vessel – or even produces an explosion. Later, in the post-incident analysis, the cylinder is incorrectly judged as to have ‘failed’. It is always suggested to install monitoring system along when setting up a suppressing agent such as Novec 1230 gas suppression system.

Fire Safety in the Cruise Industry

Could a cruise or ferry company afford to have a crippling financial, physical and probably more importantly, damage to its reputation caused by a fire that could put the passengers, crew and vessel in danger? The correct answer for everybody involved is “No.”

Fires on board ships can be devastating, to passengers, crew and vessel thus fire safety standards on board is something a passenger-carrying vessel cannot afford to slip. Part of safety standards on board a cruise ship is the maintenance of gaseous fire extinguishing installations, which may be compromised by the holes in the regulations.
It is understood that a need for practical cost-efficient solutions to safety issues is paramount. However, maintaining high standards of fire safety practice does not have to be expensive or time consuming, according to fire safety expert Coltraco Ultrasonics. You need to check out the range of monitoring devices such as ultrasonic level indicator.

Coltraco provide easy and long lasting solutions that are suitable for varying budgets. Regulations should be responded to with a rigorous attitude, to go above and beyond the rules in order to provide security of life and infrastructure. For example,

installations must be maintained so that they can provide the protection that they are intended for.

Reviewing on this factor of safety equipment; “this is a call to the industry to be aware of the problem and the action to be taken.” At sea, fire poses one of the biggest threats to ships. Sailing alone and at sea throughout the year and without the ability to call upon the emergency services, as a land-based asset might, the danger is shown in the statistics.

Although serious fires on cruise ships are ferries are very rare, a recent study published by the Finnish Transport Safety Agency showed that almost 800 fires occurred in European waters between 2004-2014 on all types of vessels. Of these some 10% of these were classed as serious. Further to this, around 200 of these incidents required external support to help deal with the fire. In some of these cases, the fire suppression installations may not have been at their full capacity, which led to uncontrollable fires, Coltraco said. Liquid gas level indicator or liquid level to mass conversion calculator  checks that these cylinders are in their full capacity.

Is a Gaseous Fire Extinguishing System enough to protect your ship from the threat of fire?

No! The reality is that installing fire-extinguishing system must be monitored once installed. Coltraco is one of the leading names in the world of ultrasonic monitoring and measuring equipment. It possesses a large number of devices for various industries on different scale. Coltraco Ultrasonic started with the range of Portalevel® – ultrasonic liquid level indicator, which has advanced and diversified now in accordance to the need of targeted industries.

Only Fire Protective Regulations cannot 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. 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 fire-fighting equipment available on board container ships. Though it may have not advanced to an appropriate extent but humans is not a perspective that can be overviewed, ever. No matter what, people are the first priority to be protected at utmost level.

Human should not be put at Risk

On an average, 400 million European passengers every year entrust themselves to the safety of the ship that they travel on. Factually, it is not a small number and any accidents on board are serious threats to the safety of those passengers. About 6% of fires on RO-RO passenger ships have resulted in loss of lives or serious injuries, every year. In December 2014, 11 people were killed and several were injured in a fire aboard the Norman Atlantic RO-RO passenger ship. Coltraco always recommend its relevant industries to make sure that chances are not taken when lives are at risk. Especially, when the vessel is at sea where zero% of land-based emergency services is available, hence the risk goes to another level.

Importance of Three Key Areas for Regular Inspection

The neglect of the basic routine testing and maintenance of three key areas substantially increases the risk of an onboard engine room fire:

  1. The cylinder agent content in the fire extinguishing installations, commonly CO2 & Marine CO2 Systems, FM-200®, Novec™1230, halons;
  2. The associated pipework;
  3. The room integrity of the protected space into which the suppressant agent discharges

Three Smart Safeship® Solutions

Here, we have enlisted solutions that you may like;

What is the “ungoverned space”?

Coltraco Ultrasonics is a British designer and manufacturer of ultrasonic safety and inspection instrumentation. With over 30 years’ experience supporting their customers in 109 countries, they are market leaders for ultrasonic liquid level technology. The ‘ungoverned space’ that is the area in the fire industry where either the regulations or the protecting systems of the critical infrastructure are not effectively providing consistent and reliable safety. Coltraco repeatedly pushed for this life-threatening issue to be dealt with, with specific regard to loss of contents in fixed fire extinguishing systems. This haphazard approach is dangerous and often unknown to the users of the infrastructure. The ungoverned space in the fire industry must end now. Spherical agents protect high value and dangerous assets, which means that their efficiency is integral. Any content loss that is accepted in the regulations and user manuals somehow removes their efficiency. This liquid level indicator is specifically designed to treat such areas, which are otherwise unreachable.

Unreachable Spheres of Fire Extinguishing Agent

Enclosed areas containing flammable hydrocarbon fuels and gases present challenging fire and explosion protection problems. Spherical agents are used as fire suppression units and occasionally to combat explosive fires where the rate of discharge of fire extinguishing agent needs to be fast to extinguish explosive fires. They are usually stored in close proximity to the equipment that it protects in a “modular” configuration and for both total flooding of a room or local application e.g. a printing press in an open area. Therefore, typically, these extinguishers protect high value or dangerous assets, which need immediate extinguishing.

Human and Financial Risk

Currently, qualified personnel are required to remove and weigh all agent storage spheres. Due to the heavy nature of these spheres, this method is not only cumbersome but dangerous to the personnel as well. Neglecting and minimal understanding of the need for maintaining the fire extinguishing systems leads to only one thing, a gap in the protection of people, assets + facilities. This leaves an “UNGOVERNED SPACE” in the protection of explosive or high value assets, which in turn endangers life.

Accessible Technology

The Portasphere® currently works on a pre-defined set of sphere dimensions and clean agents which can be easily expanded and customised by our team to specifically suit your application. This technology has been refined to enable high accuracy of liquid level identification up to +/- 10mm. By utilising the Portasphere®, the agent’s liquid level which is an indication of its contents can be found non-invasively without the need to dismantle the setup thus saving time and cost of inspection. This ultrasonic level indicator is also designed with a “one-man” operation capability in mind, allowing a variety of users to perform the testing after training has been provided.

The Portasphere® works on a basic pulse-echo theory where a single transducer is used to emit a 2 MHz pulse into a sphere, which then travels across the diameter of the sphere and reflects back from the far wall if liquid is present on the other side of the wall to conduct the signal. If liquid is not present, the ultrasound wave is not conducted through air and the Portasphere® will not give a positive readout. This process is fast and intuitive that allows routine maintenance to be conducted efficiently. This is the world’s first liquid level indicator to work on spheres.

Coltraco’s use of ultrasonic technology in monitoring equipment

Coltraco utilise the most advanced technology. Fundamentally, Ultrasound is merely sound beyond human’s audible range. Dolphins and whales can communicate at sea over long ranges as sound travels more efficiently through liquids than air. According to the words of CEO – Carl Hunter;

“The key to Coltraco’s method for monitoring those contents is ultrasound. We use sound beyond our audible range. We are broadly measuring the difference of speed and sound through different mediums. For example, sound travels more quickly through water than it does through air.”

Coltraco as Global Leader for Ultrasonic Safety/ Monitoring Equipment

Coltraco started off with a portable ultrasonic liquid level indicator that is capable of detecting the difference in speed of sound traveling through liquefied contents as opposed to the vapor space inside the bottle. It then will identify the point at which the sound travels at different speeds, thereby identifying the levels with a credible accuracy. The challenge for Coltraco in designing its new innovation is the diversity of size and thickness in the cylinders used. Adding further complication is the different surface conditions of these cylinders. Adding more about ultrasonic technology as preference of Coltraco, Hunter quoted,

“We can claim global leadership in this field because we have mastered the ability to work through everything from clean surfaces to rusted exteriors, which is common to find in older ships.”

Coltraco Assisting Data Centers with its Expertise

The U.S. Navy adopted Coltraco’s technology based on its ability to deliver accuracy to within one-eighth of an inch despite the variety of different thickness found in cylinder walls. Coltraco products are both UL (United Laboratories) listed and ABS (American Bureau of Shipping) approved.

“Aside from the marine application, Coltraco devices are most often found in electronic data centers. In America there are the world’s largest number of data centers. You might be surprised to hear that the United Kingdom has the second largest number. Helping to protect these centers is a huge application because they are designated in both countries as critical infrastructure.”

- Carl Hunter

An important part of covering data centers is determining if the protected space is able to contain the discharged gas long enough to be effective. Talking more about it, Carl added;

“At the moment, the only test for that is called a door fan test. It is used to determine if the room can withstand the force of the pressure upon gas actuation.”

However, as a structure ages it develops new leak sites. If those sites become large enough, the fire will not be extinguished so it is always recommended to possess ultrasonic leak detector on board. Fortunately, another area of expertise for Coltraco is testing watertight and weather-tight seals on-board naval vessels. This technology of ultrasound has been adapted as a means to test any protected space for leakage without performing an actual discharge. The naval bend in Coltraco’s product line is no accident. Hunter’s family has a long history of involvement in the development of SONAR, an acronym for “sound, navigation and ranging.” Quoting words of Hunter here regarding SONAR;

“Use of ultrasound in the Navy is generally called SONAR. This year is another anniversary of its first use at sea.”

The United Kingdom’s naval warfare force, the Royal Navy employed ultrasound-ranging techniques to locate German U-boats during World War I. Its original name was ASDIC (Allied Submarine Detection Investigation Committee).

“Over the next 20 to 30 years, as ASDIC developed, the Americans renamed it SONAR and that’s the term used by the Royal Navy now.”

Hunter’s father served 27 years in the Royal Navy Submarine Service then five years at the Admiralty Research Laboratory that supports the work of the Royal Navy.

“It was his concept that has enabled us to be the company we are today. And he spent half of his career working with the U.S. Navy and the Royal Canadian Navy. Work is underway to apply Coltraco’s ultrasound technology to bigger issues in industrial safety. A new device on the drawing table will be capable of measuring the contents of large-diameter storage tanks up to 150-feet in diameter. We’re not quite satisfied with it at the moment. But we’re pretty close.”

- Hunter

As per looking to the record and achievements Coltraco has made so far, it is not surprising that it achieves what is aims for. From years, it has resolved a lot of problems industries were facing regarding liquid levels, leaks, tightness, thickness, pipework and there is still so much more to come. Let us see what else Coltraco has to surprise us with!

Combatting fires around the clock?

How to in the Ungoverned Space of fire safety engineering?

Simply put, the ‘ungoverned space’ is the area in the fire industry where either the regulations or the protecting systems of the critical infrastructure are not effectively providing consistent and reliable safety. Coltraco repeatedly pushed for this life-threatening issue to be dealt with, with specific regard to loss of contents in fixed fire extinguishing systems. This haphazard approach is dangerous and often unknown to the users of the infrastructure. The ungoverned space in the fire industry must end now. Spherical agents protect high value and dangerous assets which means that their efficiency is integral.. Any content loss that is accepted in the regulations and user manuals somehow removes their efficiency.

Inaccessible spheres of extinguishing agent

Enclosed areas containing flammable hydrocarbon fuels and gases present challenging fire and explosion protection problems. Spherical agents are used as fire suppression units and occasionally to combat explosive fires where the rate of discharge of fire extinguishing agent needs to be fast to extinguish explosive fires. They are usually stored in close proximity to the equipment that it protects in a “modular” configuration and for both total flooding of a room or local application e.g. a printing press in an open area. Therefore, typically, these extinguishers protect high value or dangerous assets which need immediate extinguishing.

Spheres, like standard cylinders, suffer leak and discharge

The regulations explicitly show that the agents are at risk of leaking and becoming ineffective. In ISO 14520 9.2.1.3 the regulations explains that 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. b) Non-liquefied gases: for inert gas agents, pressure is an indication of agent quantity. If a container shows a loss of agent quantity or a loss of pressure (adjusted for temperature) of more than 5 %, it shall be refilled or replaced. The manual for Fenwal spherical agents, states that they must be weighed and inspected semi-annually. Losses of agent must not exceed 5% in net weight, or 10% reduction of pressure. Essentially, it is  acknowledged in regulations that the gaseous systems lose their agent over time through issues such as leaking  and need to be maintained.

Risks to life and asset

Currently, qualified personnel are required to remove and weigh all agent storage spheres. Due to the heavy nature of these spheres, this method is not only cumbersome but dangerous to the personnel as well.

Answering the ungoverned space!
To counteract this issue, Coltraco Ultrasonics have designed a smart solution for the maintenance of the spheres. The Portasphere® is a portable non-invasive liquid level indicator that identifies the fill levels of almost any liquid in single skinned spheres. It is the world’s first non-invasive ultrasonic liquid level indicator specifically designed to function on spheres. From water and liquid pressurised gases to firefighting clean agents.

Coltraco as One of the Leading Manufacturer for Ultrasonic Safety Equipment

Do you have nay idea how bad something can react if it is kept under extreme pressure? Take yourself as an example; if something applies a physical force upon you, the instant reflex behavior is that you will react with the same power in return. Similarly, this formula works with Pressure vessels. The stronger the pressure, the biggest eruption it should be expected to make. You should never be fooled by they appearance as it is unremarkable and dull but they can be a huge mess if the gases packed tightly in them under high-pressure finds it way out.

UK-based Coltraco Ultrasonics is in the business of monitoring such to determine that the liquefied and non-liquefied gaseous contents are there and in the quantity required in an emergency. With applications in marine and fire safety, the instrumentation and monitoring systems manufactured by Coltraco guarantee that the fixed liquefied gaseous fire extinguishing systems are ready to operate in the “ungoverned space” which is what the company CEO Carl Hunter refers to it as:

“The ungoverned space is defined as the areas in relation to special hazards where gaseous extinguishing systems are used.”

Coltraco being the top Manufacturer for Ultrasonic Monitoring Devices

Now talking about fixed fire extinguishing system, these liquefied gases vary from CO2 & Marine CO2 Systems, halons whereas now these are mostly replaced by fire fighting agents such as FM 200 and Novec 1230 gas suppression system. The major reason of kicking out Halons out of this list is because it was considered harmful for ozone layer but it is still available for use in rare areas. Nitrogen and Inergen fall in the category of non-liquefied gases for blowing out fire flames. There is usually a pressure gauge placed as only monitoring device to make sure that it is adequately charged for emergencies.

Another really effective way to verify the liquefied gas level is to calculating fire suppression agent weight.

Before quoting Carl’s words here in reference to above discussion, let us tell you what makes Coltraco so different and reliable. Today, it is widely spread company striving from dawn to dusk to facilitate the industries with better options to monitor the security systems they have already installed.

“On a huge commercial ship there might be as many as 600 100-pound cylinders. You can imagine that it would take an incredibly long time to service that ship.”

  - Carl Hunter -  CEO Coltraco

Furthermore, he added about his company: “The key to Coltraco’s method for monitoring those contents is ultrasound. We use sound beyond our audible range. We’re broadly measuring the difference of speed and sound through different mediums. For example, sound travels more quickly through water than it does through air.”

What is Ultrasound?

Ultrasound is merely sound beyond humans’ audible range. Dolphins and whales can communicate at sea over long ranges as sound travels more efficiently through liquids than air.This technology comes with high accuracy and reliability for the data.

Onboard Engine Room Fires and Fire Suppression Monitoring Systems

Fire is unacceptable and threatening to ship especially at sea. It can be harmful for cargo, vessel and crew. According to the research conducted by IMO, it has been observed that the core place of fire happening is engine room and basic reason is regarded to be the oil leaks from pressurised systems. It makes up to 70% of the entire number of fire happening in merchant ships around the globe.

Role of Engine Room in Fire

In the marine sector, there are two types of engine room; either operated on electric power or oil. As a matter of fact, due to heavy power supply, running machinery, there are large sources of fuel and ignition, it is really expected that fire may take place if proper care is not given to it. Another reason for uncontrollable fire is about poor fire extinguishing system-monitoring devices.

To read more about how engine room participates in fire, check out our article at ABC.

Significance of Fire Extinguishing Monitoring System

Sinking and fire are the biggest causes of vessel loss. A vessel sails alone and in the event of an emergency there is no land-bases asset or emergency service to rely on. It is recommended to have an ultrasonic liquid level indicating system, which can provide the details throughout the day without regular manual input. Safety in this era always demand to stay ahead as far as technology is concerned because the better you invest, the more you have.

Being reluctant to spend on security and safety system can lead you to high expenses, it can cause salvage, downtime, repairs, cancellation and most importantly, damage to the asset onboard including human lives.

Advancement in Fire Suppressing Monitoring System

According to the Vice Chairman at IUMI – International Union of Marine Insurance, fires on container ships is regarded to be among the worst hazards on global shipping level. Coltraco’s liquid level indicator caters to the marine industry. Coltraco offer highly qualified researchers and professional manufacturing with advanced technology.

IBCs Food Processing

Background

Food processing factory based in the south of the UK producing Coleslaw, packaged salads and pastas for the likes of McDonalds, Tesco, Morrisons, Lidl. Producing over 130,000 pots of Coleslaw a day.

Application

2.2 metre high, 5mm stainless steel wall, filled with mayonnaise to be used for the Coleslaw. The current monitoring method consists of employing ladders to peer into the cylinder and check usage and remaining contents. The issue with this method lies in potential contamination and is a health and safety risk to the operator.

Solution 

A site visit was conducted by Coltraco Engineers and after a short trial we were able to gauge that the existing liquid level indication technology employed on the Portalevel® Max liquid level indicator would be efficient in quickly and accurately gauging the liquid level of mayonnaise within the vessel.

Implementation

The implementation of the Portalevel® Max allows the plant to run more efficiently and reduces risks by providing the staff with a means of accurately and non-invasively monitoring the contents within the mayonnaise tank negating the need for physical inspection using ladders posing a health and safety risk to the operator.

Possibilities

The trial and implementation suggested that we could develop a fixed monitoring system for this vessel and others like it, in order to non-invasively; continuously monitor the contents of mayonnaise (or any other condiments) within the tank. In addition we also saw possibilities to refine the capabilities of the Portalevel® Max to increase ease of use.

Efficiency of Coltraco’s Permalevel® Multiplex

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. It gives a facility total visibility on the real-time status of all their critical fire systems.

Modern fire suppression systems have transformed industry safety across all sectors. However, the development of their servicing and monitoring equipment has remained stagnant, with many very advanced systems relying totally on annual inspections, or on unreliable mechanical pressure gauges. These methods leave the status of fire suppression systems completely vulnerable between annual checks.

Coltraco are raising awareness that annual certification checks on a fire system cannot cater for the need to monitor its contents for the rest of the year. The Permalevel® Multiplex is designed to ensure that fire suppression systems with integrated alarm system and ultrasonic level indicator 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.

Permalevel® Multiplex Data Monitoring

Remotely monitor the ongoing status of your facilities' fire suppression systems by installing Permalevel® Multiplex and using our flexible web- based cylinder monitoring software that uses intuitive management tools; giving confidence and control to safety managers around the world.

How to get into the inaccessible space of fire safety engineering?

Have it been a problem to access tough areas of fire suppressing system? Well, here you can get the solution with Coltraco now as it presents you with the world’s first liquid level indicator to work on spheres!

Inaccessible spheres of extinguishing agent

Enclosed areas containing flammable hydrocarbon fuels and gases present challenging fire and explosion protection problems. Spherical agents are used as fire suppression units and occasionally to combat explosive fires where the rate of discharge of fire extinguishing agent needs to be fast to extinguish explosive fires. They are usually stored in close proximity to the equipment that it protects in a “modular” configuration and for both total flooding of a room or local application e.g. a printing press in an open area. Therefore, typically, these extinguishers protect high value or dangerous assets which need immediate extinguishing.

Spheres, like standard cylinders, suffer leak and discharge

The regulations explicitly show that the agents are at risk of leaking and becoming ineffective. In ISO 14520 9.2.1.3 the regulations explains that the storage container contents shall be checked at least every six months as follows:

  1. 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.

The manual for Fenwal spherical agents, states that they must be weighed and inspected semi-annually. Losses of agent must not exceed 5% in net weight, or 10% reduction of pressure. Essentially, it is acknowledged in regulations that the gaseous systems lose their agent over time through issues such as leaking and need to be maintained.

Risks to life and asset

Currently, qualified personnel are required to remove and weigh all agent storage spheres. Due to the heavy nature of these spheres, this method is not only cumbersome but dangerous to the personnel as well. Neglecting and minimal understanding of the need for maintaining the fire extinguishing systems leads to only one thing, a gap in the protection of people, assets + facilities. This leaves an ‘ungoverned space’ in the protection of explosive or high value assets, which in turn endangers life.

Answering the ungoverned space!

To counteract this issue, Coltraco Ultrasonics have designed a smart solution for the maintenance of the spheres. The Portasphere® is a portable non-invasive liquid level indicator that identifies the fill levels of almost any liquid in single skinned spheres. It is the world’s first non-invasive ultrasonic liquid level indicator specifically designed to function on spheres. From water and liquid pressurised gases to firefighting clean agents.

Accessible Technology

The Portasphere® currently works on a pre-defined set of sphere dimensions and clean agents which can be easily expanded and customised by our team to specifically suit your application. This technology has been refined to enable high accuracy of liquid level identification up to +/- 10mm. By utilising the Portasphere ®, the agent’s liquid level which is an indication of its contents can be found non-invasively without the need to dismantle the setup thus saving time and cost of inspection. This device is also designed with a “one-man” operation capability in mind, allowing a variety of users to perform the testing after training has been provided.

The Portasphere® works on a basic pulse-echo theory where a single transducer is used to emit a 2 MHz pulse into a sphere, which then travels across the diameter of the sphere and reflects back from the far wall if liquid is present on the other side of the wall to conduct the signal. If liquid is not present, the ultrasound wave is not conducted through air and the Portasphere® will not give a positive readout. This process is fast and intuitive that allows routine maintenance to be conducted efficiently.

How to test room integrity with the Portascanner® 520?

It has been more than 30 years now that Coltraco is bringing the most upgraded ultrasonic monitoring and safety equipment without any compromise on quality. Now, it has launched 2nd generation of Portascanner 520 that is an ultrasonic room integrity tester complementing door fan-testing device. Here are some of the features for complying with regulations for clean agent fire suppressing systems, give it a look!

Current Situation:

Before installing clean agent fire suppressing systems the integrity of the building structure commonly undergoes “Door Fan Testing:. This test determines the Peak Pressure and Agent hold time necessary for ensuring the effectiveness of these fire suppression systems. As required by NFPA 2001 and ISO 14520 standards, it is best to calculate the overall leakage of any room.

Limitations:

Locating exact leak sites as an ultrasonic leak detector is currently done by a “puffer test” with smoke. However, such current methods do no provide precise, accurate results on leak location or size.

Solution:

Today, the industry can benefit from using the Portascanner Integrity Test Indicator along the door fan testing for a complete and comprehensive regulatory room test. Ideal for precise leak detection, Portascanner 520 is an exceptionally accurate up to 0.06mm and fast method to find leaks. It is the first of its kind, intuitive to use, non-invasive and consequently, is of immediate use to the fire industry.

How s the Portalevel® MAX INDUSTRIAL useful for the Aerospace Industry?

The Portalevel® MAX INDUSTRIAL is the latest generational of the Portalevel® line and is designed to provide enhanced Speed, Operation and Performance, especially for high intensity testing requirements. The unit is also the first UL Approved Ultrasonic Level Indicator we have ever produced and builds further on our history of over 30 years manufacturing this equipment.

Background:

Coltraco is known as a manufacturer of high-end components for Aerospace and other high-end engineering. The Wolverhampton facility runs 24/7 and 365 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 defense systems.

Solution:

A Coltraco Engineer visited the site to conduct technology suitability trials. Our technology in this ultrasonic liquid level indicator was found to be effective in accurately and quickly identifying the liquid level within the ammonia cylinders.

Implementation:

  • It was recommended that a standard un- altered Portalevel® MAX INDUSTRIAL would be a suitable solution.
  • We also cooperated with the customer to develop an in-house testing and recording process that was compatible with their current processes.
  • The solution provided a quick and accurate non-invasive solution, which allowed for more efficient operations and reduced waste by ensuring partially empty cylinders were not returned to the gas supplier.

    Applications:

    The facilities manager of the factory met with us at the Facilities Management show in Birmingham weeks prior. We were informed
of the need to monitor the contents within Ammonia Cylinders. The customer uses ammonia in a nitrating process in which ammonia is applied to a heated metal infusing the metal with Nitrogen. This can have beneficial properties such as making the metal harder/tougher/higher melting temperatures etc. Presently, weighing techniques are used to ensure a cylinder has enough contents for a run. This has been shown to be ineffective and incur waste; a non-invasive method would be quicker, reduce waste and save money.

    Possibilities:

    The trial and implementation suggested that we could develop a fixed monitoring system for this agent to non-invasively constantly monitor their cylinder contents. This also stimulated interest in developing an Ammonia Portasteele® program to allow you for calculating fire suppression agent weight.

Coltraco’s ATEX Approved Portalevel® MAX Intrinsically Safe

Addressing fire at sea is critical, especially when all owners and managers are seeking to reduce risk, cut costs and surge on safety. The safety of tankers are integral for the continuation of their business success. Catastrophic risks to human life, vessel, reputation and revenue all result from a fire event onboard. To cater for customers who need to inspect fire systems in the dangerous environments that tankers present we have developed the ATEX Approved Portalevel® MAX specified to Zone 1 environments.

This device was created after requests from Shell and similar Tanker Operators to supply a solution to ensure their fire safety when carrying dangerous cargo. The International Maritime Risk Rating Agency (IMRRA) has ranked fire safety as the leading tanker deficiency seen by Port State Control for the first six months of the year. In March 2017 there were 152 cases of fire reported. The IMMRA placed 12.5% of tankers it assessed in January 2017 into the higher risk category – a six month high.

Serious cases of tanker fires and risks have been reported in the past year. In September 2016 a Pemex oil tanker had a serious fire in the Gulf of Mexico, on which it was carrying 80,000 barrels of diesel, 71,000 of gasoline and 16,000 barrels of desulfurized gasoline. 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. Even as recently as July fire safety is still being neglected, with the crew of the tanker MT IBA reporting empty fire extinguishers (despite transporting crude oil) and leaking life boat’s hydraulic system with no means of testing.

Designed for explosive atmospheres on tankers, the ultrasonic liquid level indicator offers fast operation – a cylinder can be serviced in under a minute, with accuracy of up to 1.5mm off the true liquid level, all housed in a portable and rugged unit, which has a 10 hour battery life.

Portalevel® MAX Industrial Transformer Application

INDUSTRY: ELECTRIC POWER TRANSMISSION & DISTRIBUTION

APPLICATION: TRANSFORMER OIL LEVEL

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.

Application

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. High voltage transformer and switch gear units are also 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. 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.

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. This contributes to more frequent oil changes, significant downtime to the system when an oil change is conducted and the formation of sludge which reduces efficiency. A non-invasive oil monitoring liquid level indicator is necessary.

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 INDUSTRIAL 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.

Possibilities

Many companies around the world are beginning to use the Portalevel MAX INDUSTRIAL 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.

Portalevel® MAX Pharmaceutical Applications

INDUSTRY: PHARMACEUTICAL MANUFACTURING

APPLICATION: AMMONIA LEVELS IN IBCS - ATEX

Background

A British pharmaceutical company, one of the largest in the world. We received a request from one of their pharma manufacturing plants in Ireland, the plant produces active ingredients that are used in drugs used to treat cancer, Parkinsons + depression.

Applciation

We received a request to deliver a means to non-invasively monitor the contents within IBCs (Intermediate Bulk Containers). The ammonia is used to breakdown manufacturing by-products before they are then safely incinerated. An ammonia/water mix is delivered onto the site in IBCs. The current method of monitoring the contents within these IBCs involved physical dip stick measurements on the tank to monitor usage and replacement. This methodology stemmed from a lack of confidence in the internal IBC monitoring system. However, the fumes given off by the ammonia creates a health risk for engineers. Opening the top valve also creates risk of contamination to the ammonia. They therefore require a non-invasive method.

Solution

A Coltraco Engineer visited the site to conduct technology suitability trials. We surveyed several of the IBCs some were partially full and some were fully empty - after adjustments we determined general range for a full and empty state across 7 of the IBCs. Trial indicated real potential for us to deliver a solution for this application.

Implementation

Once proven that our technology was suitable, these specifications had to be met:

  • Non-Invasive and ultrasonic
  • Application Specific Calibration – 0=LIQUID 100+=AIR (unapparelled ease of use)
  • Intrinsically safe
  • Robust enough for daily use
  • Magnet not required
  • Specifically designed for the application

Over the next 4 weeks we developed a turn-key solution offering:

  • unparralled accuracy
  • ease of use and
  • clarity of indication
  • on an Intrinsically Safe unit
  • no input required from the operator apart from the application of the sensor to the vessel wall.

Result

First technology of its kind because a non-invasive solution did not previously exist. It enables operators to safely, quickly and accurately monitor contents within ammonia vessels which are integral to the entire plant operation. The equipment will also reduce the amount of partially empty ammonia cylinders returned before emptying, saving the organisation money over time.

Portalevel® MAX Industrial Aerospace Application

INDUSTRY: AEROSPACE COMPONENT FACTORY

APPLICATION: AMMONIA LEVELS IN CYLINDERS

Background

Manufacturer of high end components for Aerospace and other high end engineering. The Wolverhampton facility runs 24/7 365 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 defense systems.

Application:

The facilities manager of the factory met with us at the Facilities Management show in Birmingham weeks prior. We were informed of the need to monitor the contents within Ammonia Cylinders. The customer uses ammonia in a nitriding process in which ammonia is applied to a heated metal infusing the metal with Nitrogen. This can have beneficial properties such as making the metal harder/tougher/higher melting temperatures etc. Presently, weighing techniques are used to ensure a cylinder has enough contents for a run. This has been shown to be ineffective and incur waste; a non-invasive method would be quicker, reduce waste and save money.

Solution

A Coltraco Engineer visited the site to conduct technology suitability trials. Our technology was found to be effective in accurately and quickly in identifying the liquid level within the ammonia cylinders.

Implementation:

It was recommended that a standard un-altered Portalevel® MAX INDUSTRIAL would be a suitable solution.

  • We also cooperated with the customer to develop an in-house testing and recording process that was compatible with their current processes.
  • The solution provided a quick and accurate non-invasive solution which allowed for more efficient operations and reduced waste by ensuring partially empty cylinders were not returned to the gas supplier.

Possibilities:

The trial and implementation suggested that we could develop a fixed monitoring system for this agent to non-invasively constantly monitor their cylinder contents. This also stimulated interest in developing an Ammonia Portasteele® program to allow the accurate conversion of liquid level to agent mass.

Portalevel® MAX Industrial Application Steel Transformer

INDUSTRY: STEEL PRODUCTION FACILITY

APPLICATION: TRANSFORMER OIL LEVEL

Background

Transformers are used in electric power transmission and distributions and are devices that transfer electric power at different voltage levels. There are two types of transformers that were present on site: (1) 33kV to 6.6kV and (2) 6.6kV to 440V where the former is much larger sized. Both types contain tapchangers and cable boxes which are filled with oil or a fluid compound essential for the operational of the transformer. Across the site, there are approximately hundreds of such transformers installed.

Application:

Many of these transformers do not have the means to indicate oil / fluid level externally. The existing solution is to shut the transformer down and inspect oil levels by opening the covers which results in a significant downtime to the power distribution network in the production facility. There were also concerns in the accuracies of many of the existing built-in level meters in the tank.

Solution:

The Portalevel MAX INDUSTRIAL is identified to be a portable and reliable non-invasive solution capable of identifying fluid levels quickly and is very simple to operate. Oil inspection can now be done externally and on “live” transformers. Inspecting with increased efficiency, the oil inspections can now be conducted routinely saving overall maintenance and labour costs as only a single user is required to operate the equipment.

Implementation

A standard unaltered Portalevel MAX INDUSTRIAL is sufficient for the application. We also supplied the “Special Applications” sensor along with the unit to ensure stronger and more efficient power output from the device capable to identify oil levels across the full range of their transformers.

Result

Safety critical tool which minimises risk to human life by ensuring inspectors can identify the oil level even when it cannot be cannot be seen in a sight glass or other method.

Application

2.2metre high, 5mm stainless steel wall, filled with mayonnaise to be used for the Coleslaw. The current monitoring method consists of employing ladders to peer into the cylinder and check usage and remaining contents. The issue with this method lies in potential contamination and is a health and safety risk to the operator.

Solution

A site visit was conducted by Coltraco Engineers and after a short trial we were able to gauge that the existing liquid level indication technology employed on the Portalevel® MAX INDUSTRIAL would be efficient in quickly and accurately gauging the liquid level of mayonnaise within the vessel.

Implementation

The implementation of the Portalevel® MAX INDUSTRIAL allows the plant to run more efficiently and reduces risks by providing the staff with a means of accurately and non- invasively monitoring the contents within the mayonnaise tank negating the need for physical inspection using ladders which pose a health and safety risk to the operator.

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.

My kindest regards,
Carl
