How can crew test their CO2 installations without disturbing them?

As stated in IMO SOLAS FSS Ch5. “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. To overcome this, ships need to test their CO2 systems for contents in-between the annual certification checks by marine servicing companies.

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 indicators, 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.

Solutions for any vessels marine gaseous extinguishing system exist:

  • Portalevel® MAX Marine liquid level indicators used by the crew weekly to test for contents
  • Portascanner® WATERTIGHT, watertight integrity test indicators used by the crew to test for compartmentation
  • Portapipe® pipework integrity indicators used to test for pipework obstructions and the Portagauge® thickness gauges for pipework corrosion
  • Compressed air testing of the pipework and flanges to test the pipework system’s ability to withstand the pressures of the gas on actuation (and this is the only test which recommended to be solely the responsibility of a  “responsible” shore-based contractor)
