Coltraco manufacture Ultrasonics That Work

“Safely check the quantity of the fire extinguishing medium in the containers.”

Sailing alone and at sea throughout the year, and without the ability to call upon the emergency services as a land-based asset might. This is recognised with marine insurers and especially with the International Union of Marine Insurance (IUMI): “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.”

As vessels become larger and more sophisticated, a greater financial interest is tied up into one ship, meaning that the risks are magnified if the vessel would get into difficulties e.g. a fire. From a marine insurer's perspective, it is a simple equation: the larger the vessel, the more cargo it will carry, and hence the greater the sum insured.

Posed threat of loss of crew, vessel and the cargo guidance by the German Insurance Associations has set out an ‘improved concept’ for firefighting facilities on container ships. Vice Chair of the IUMI Loss Prevention Committee, Uwe-Peter Schieder, explained: “We believe a new technical solution is needed to improve current firefighting practice on container vessels, particularly as these ships are continuing to grow in size

The regulations that currently govern gaseous extinguishing systems are the IMO SOLAS Fire Safety Systems (FSS) Code and the BS EN ISO 14520 standards.

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

Coltraco Ultrasonics is aware of that there is failure to fully implement the regulations. Coltraco supply Marine Servicing companies globally share anecdotes - that at any one time the average merchant vessel in non-UK port visits has over 20% of its CO2 cylinders empty on inspection plus another 10-20% which have contents loss and also know that occasionally marine “servicing companies” unintentionally leave it disabled.


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 indicator, 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.


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,
