Ti Group, a subsidiary of Wilhelmsen Technical Solutions (WTS), has completed the gas trial for the first LNG carrier built to a boil-off rate (BOR) of 0.08% per day.  

The gas trial test was completed on the LNG carrier Seishu Maru, currently under construction at Mitsubishi Heavy Industries (MHI) in Japan for NYK Line.

Ti Group was responsible for supplying the cargo tank insulation system on Seishu Maru, one of six LNG carriers to be delivered in this order. The LNG carrier is a next generation Sayaendo design vessel, with a cargo capacity of 150 000 m3. This design features four spherical Moss tanks protected by a continuous cover integrated with the ship’s hull.

The LNG carrier passed its gas trial and was delivered to the owner in late September 2014.

Ti Group Managing Director, Anstein Sorensen, said: “The gas trial is one of the critical tests to pass before the ship can be handed over to owner because it proves that the vessel’s containment system, including the insulation, is working correctly […] Passing the test at a BOR of just 0.08% is a milestone for the project and sets a standard that reflects our knowledge and expertise in this area.”
