Addressing these two main causes of vessel loss are critical, especially when all owners and managers are seeking to reduce risk, cut costs, surge on safety and protect seafarer welfare. Gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use, shown in the regulations that demand their upkeep e.g. IMO SOLAS FSS Ch5. The systems are pressurised approximately 24-29 bars, higher than a standard cup of water which is 1bar. It’s accepted that these systems are not passive but dynamic, thus requiring monitoring. The traditional method requires turning the system off, dismantling and manually weighing each cylinder on industrial scales. Routine maintenance is liable to be overlooked because the crew is unqualified to test or insufficient attention is given by the owner of the system. It’s neglected to the peril of the lives of occupants of the ship and at the risk of crippling financial and reputational loss to the owners.

The Portalevel® MAX Marine is designed primarily for maritime applications where either third party service companies or the vessels’ crew themselves, inspect large fire suppression systems of up to 600 cylinders. Innovative methods of inspecting leaking cylinders with ultrasonics, enables identification in under 30 seconds using Portalevel® MAX Marine with one person, instead of the traditional 15 minutes, with two people labouriously shutting down the system, dismantling the cylinders and weighing them. Using ultrasonic technology – to pinpoint the liquid level of suppressant agent in the cylinders of the extinguishing system – testing is quicker and easier. The ease of operation in comparison to weighing, increases the ability of more regular and frequent checks, improving fire safety management onboard. Portalevel® MAX enables its users to go above and beyond minimal regulations compliance, thus becoming industry leaders. Combined with the Portasteele® Calculator, the weight can be found in just 30 seconds more. It is an advanced calculator application, that converts the liquid level height of C02, NOVEC™ 1230 or FM-200® liquefied gaseous extinguishant agent readings taken on the Portalevel® into the agent weight/mass. There is no other similar alternative to weighing available on the market. Furthermore, the Portasteele® can convert an expected agent weight back to the required liquid level allowing users to anticipate where the level should be. This method also enables recording and downloading of the data, adding value to servicing reports and improving the safety management system for a auditable data trail.
