GTT, the world leader in the design of membrane containment systems for the maritime transportation and storage of LNG (Liquefied Natural Gas), announces that its new containment system Mark V has been granted General Approval for Ship Application (GASA) by the classification society DNV-GL.
The validation by DNV-GL of the Mark V technology is a major step towards its rapid commercialization following two cooperation agreements GTT signed during the First Half of 2015 with the shipbuilders Hyundai Heavy Industries and Samsung Heavy Industries to confirm the industrialization of the system.
After some years of research and development, the Mark V technology is an optimized version of the Mark III system and its sister Mark III Flex. As with the Mark III and Mark III Flex, the Mark V technology is composed of a double insulation with reinforced polyurethane foam. The new system also includes an innovative nickel-steel alloy corrugated secondary membrane and offers significant improvement of the warranted daily boil off rate.
Philippe Berterottière, Chairman and CEO of GTT commented: “This General Approval by DNV-GL marks our innovation effort at the service of the LNG Industry and is the recognition of the reliability of GTT technologies. This milestone will give shipowners further confidence in the performance of Mark V”.
