New standard set for LNG containment systems

The test was carried out on LNG carrier Seishu Maru, for which TI Group supplied the cargo tank insulation system. Currently being built at Mitsubishi Heavy Industries (MHI), the vessel is a next generation Sayaendo design vessel, with a cargo capacity of 150,000m³. The unique design features four spherical Moss tanks protected by a continuous cover integrated with the ship’s hull.

“The gas trial is one of the critical tests to pass before the ship can be handed to owner because it proved that the vessel’s containment system, including the insulation, is working correctly,” said Anstein Sorensen, managing director, TI Group.

“Passing the test at a BOR of just 0.8% is a milestone for the project and sets a standard that reflects our knowledge and expertise in this area,” he added.

TI Group provides two options for cargo tank insulation based on different technologies. The panel system is an adaptable solution for LNG/LEG/LPG cargo tanks, with a design that can be fitted to most tank geometries. The company also offers an efficiency and economical insulation system for LPG carriers, based on spray foam technology.
