Fires Happen: it’s Time to Act

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.) 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.

Taking CO2 & Marine CO2 Systems through as an example, although random checks may be suitable in some sectors, it is worth remembering that because the normal design concentration of CO2 of 34-72 v/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 oxygen levels during an accidental discharge may allow a situation to spiral out of hand.

“CO2 bottles leak”

Yet although this poses high levels of risk to the service companies and the crew, because gaseous extinguishing systems are highly pressurized, the risk of leaking and discharging is accepted as part of their use and this is shown in the regulations that demand their upkeep e.g. 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 – the traditional method.

A Call for Crew to Inspect Fire System Cylinder Contents

Using an ultrasonic liquid level indicator is the only way that the crew can safely test their CO2 without disturbing them. If marine 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.

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.

 

CEO Message

Integrity and Science Key to Our Culture of Performance

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
