Interviee with CEO Dr Carl Hunter.
“Given both the crew lives and cargo at stake, it seems unfathomable that these systems are not permanently monitored rather certified just once a year, particularly since it is a regulatory obligation to ensure that crew are in a position to check these,” Hunter says. Safety of Life at Sea’s (SOLAS) International Fire Safety Systems (FSS) code states that “means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers”.
It can be argued that the existence of regulation (such as that set by the the IMO and other authorities) guides – and occasionally curbs – the direction taken by the free market. This then means that the current state of the market, where ‘price is king’ is either due to unwillingness on the part of the regulators to create an environment where safe engineering is rewarded or because the industry itself is unaware of new technology that will help them meet both the spirit and letter of the regulation.
The fact of the matter is that technologies exist right now that can easily and accurately monitor everything from gases under pressure to liquefied contents and corrosion of pipework. The traditional method of using a cylinder pressure gauge (located at the meeting point of valve and neck of a pressurised cylinder) is both obsolete and impractical – especially when cost cutting may result in use of minimally-compliant gauge mechanisms.
Technologies will soon exist that will offer devices that monitor both liquid content and gas pressure safely from the external sides of the cylinder rather than within it. This means that crew will be able to monitor the contents and then calculate the mass/weight of the liquefied extinguishant. By measuring the pressure of the gas on top of the liquefied extinguishant they can can assess the pressure of an Inert gas (which is in an entirely vaporous form) to ensure that the cylinder is primed to perform when needed.
Having systems that operate transparently will work not just to convince a vessel owner that his asset is in good hands, but also to reassure the crew that their safety is taken seriously by both – their employer and the marine servicing company.
Its portfolio boasts 11 different model types of Portalevel brand liquid level indicators including Portascanner (which uses ultrasound to test the integrity of confined spaces and can detect leak sites as small as 0.06mm) and Portagauge (which uses ultrasound to test the internal and external corrosion on pipework and cylinder wall thickness to an accuracy of +/-0.1mm). “We can monitor these 24/7 with the fixed, data-logging and autonomous monitoring system, Permalevel Multiplex & Permalevel Single Point,” says Hunter. “Signals from these fixed monitoring sites can be monitored centrally on the bridge and in the ship’s technical office concurrently. We see a day when products and systems will be designed that will monitor gas vapour above the liquid level and inert gases too.”
