Vessel stability and vessel fire safety

Shipping professionals understand that any marine structure “turns and bends” as it sails, that its extent is affected by its sea, weather and its load states and that as a structure ages its integrity changes and worsens. They understand that a pressurised fire extinguishing gas is effected by temperature and that its cylinder holding structure and its associated pipework corrodes over time. They know well that a fire at sea can only be dealt with two ways - by the ships’ extinguishing system or the crew. Portalevel™ MAX Marine and Portascanner™ Watertight are therefore in service in over 20% of the world’s fleet of ships, across the leading 20 Navies and in most of the world’s Oil & Gas Platforms. They are at the heart of the IMO SOLAS FSS code enabling Officers and Crew to test in port and at sea either their fire systems or their watertight integrity.

Coltraco Ultrasonics designed the world’s first portable ultrasonic liquid level indicator which developed into the world’s first portable ultrasonic watertight integrity test indicator. These were designed respectively to give to Shipping safe, environmentally-friendly products and systems to replace existing labour-intensive and environmentally-damaging means to help secure these safety risks. In a Ships’ CO2 system, there may be 600 x 45KG/100 lb cylinders of CO2. The CO2 is a highly effective gaseous extinguishant designed to displace oxygen and suppress a fire in a ship. But they are under extreme pressure, often more than 50 Bar, and they can leak or accidentally discharge. If personnel are around when they discharge fatalities can occur. They must be physically dismantled, weighed and re-installed for maintenance, which the crew is not licensed to do so. 30 years ago, marine servicing companies used radioactive-sourced level indicators, but these were damaging to health and subject to IATA transportation, licensing and storage requirements. Coltraco Ultrasonics designed a portable ultrasonic liquid level indicator, now called the Portalevel™ MAX Marine and today it is the worlds most widely used liquid level indicator in ships’ CO2 and NOVEC™ 1230 systems.
