Save lives! How & why to improve water mist maintenance.

Despite the difficulty that shipping businesses are subjected to, fire safety standards on board cannot begin to slip. Fires on board ships can be devastating, to crew, vessel and cargo. There is a call to respond to regulations with a rigorous attitude, to go above and beyond, to provide security of life and infrastructure. Water mist fire suppression systems must be maintained so that they can provide the protection that they are intended for: protecting lives, assets and vessels whilst at sea.

Assessed by FM Global, one of the main causes of failure to water mist systems derives from human error, commonly the water tank being empty. If there is a lack of water supply, the system will be dysfunctional when required, such as failing to extinguish the fire and thus,resulting a significant risk in safety and high-asset applications. Organisations such as the Maritime and Coastguard Agency (MCA) have called for the correct installation and maintenance of Water Mist systems. 

For a system that fully relies on the supply of pressurized water, if there is no availability of this source of water, there is no possibility of fire depletion exemplified by the MCA: “effective fire-fighting can only be achieved when the water mist is released promptly on demand.” This is demanded by the IMO regulations MSC.1/Circ 1432, Ch 5.4: “Verify that sprinkler pressure tanks or other means have correct levels of water”. Further to the NFPA 750 regulations state that “Water Storage Vessels must be equipped with a means of checking the level of water inside during a weekly or monthly inspection. Some high-pressure storage cylinders do not have a means to confirm water levels. If such cylinders are present in a system, extra measures should be implemented.” There is an industry wide recognition that these cylinders need monitoring for the safety of the crew and vessel. Ultrasonics is an innovative technology to answer this call.

To ensure that Water Mist systems are fully operational in the event of a fire, and to avoid the serious risk of empty cylinders, the liquid level indicator of the cylinders should be checked non-invasively using ultrasound. 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. 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.

Better maintenance of water mist fire suppression systems will save lives. Innovative ultrasonic technology enables the crew to be in full compliance of the regulations at all time, delivering a Safeship to protect the lives of crew/passengers/cargo and vessel, quicker, better and more effectively than other traditional methods.


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,
