FIRE SAFETY IS MORE THAN ANOTHER TICKBOX

FIRE SAFETY IS MORE THAN ANOTHER TICKBOX

There are 55,000 ships in the world carrying 95% of all commodities and goods. 25% of these are Tankers, Chemical Carriers & Product Tankers. 40% of these are Bulk Carriers and General Cargo ships. These have a need for vessel integrity and vessel fire safety.

Currently it is well known that the shipping industry has taken a big hit in certain areas. The amount of “urgent” supply requests that increase during one of shipping’s cyclical down-turns is because it is during these times when owners risk vessel detention by not placing safety critical equipment on-board. There are two key aspects to investigate in more detail because they are oft overlooked: the ungoverned spaces of fire safety and watertight integrity. These two areas will be examined through the regulations and technologies used to solve these issues. Looking at the UK as leaders in the shipping industry worldwide with a case study focus on a British designer and manufacturer who is sailing through the tough times.

Engine room fires are often reported but there are many more instances where problems with the fire system may not reach the public eye. In a ship’s fire extinguishing system, there may be 600 x 45kg/100lb cylinders of CO2. The CO2 is a highly effective liquefied gaseous extinguishant designed to displace oxygen and suppress a fire. But they are under high pressure, often more than 50 Bar, and they can leak or accidentally discharge. Common knowledge suggests 20% of marine CO2 cylinders leak. If personnel are around when they discharge fatalities can occur. To inspects cylinder contents, the system is turned off, the cylinders dismantled, weighed and re-installed by certified personnel, which the crew are not. 30 years ago, marine servicing companies used radioactive-sourced level indicators, but these were damaging to health and subject to IATA transportation, licensing and storage requirements. The first handheld liquid level indicator to use ultrasonic technology provided a quick, accurate and safe means for anyone trained - from a marine servicing company, to chief engineer or crew member - to test the cylinder contents. This Portalevel® was designed and manufactured by Coltraco Ultrasonics who have since developed the technology to the 8th generation Portalevel® MAX Marine which can test all common clean agents.

LEAKING HATCHCOVERS? DOORS & MCTs MUST NOT BE FORGOTTEN.

A second key problem area for vessels is the watertight integrity: for example, 33% of cargo claims are due to leaking hatch-covers. Not only hatch-covers suffer seal integrity issues, but also the multiple cable transit areas, cable penetrations between bulkheads or watertight compartment doors. Historically the industry has used high pressure water hoses or chalk compression testing to test the seals.  These methods are messy, inaccurate, time-consuming and the environmental implications of water run-off is costly. They can also only be conducted when the ship is in port or when the cargo holds are empty.  Portascanner™ Watertight was designed by Coltraco Ultrasonics to meet the need for a clean, simple, highly accurate means to achieve watertight integrity in port, with or without cargo in the hold. It is handheld, intuitive to use, with audible and visual displays showing the most mathematically accurate results of its type worldwide.
