GTT technology receives DNV GL validation

Published by
LNG Industry,

GTT’s Mark V containment system has been granted General Approval for Ship Application (GASA) by DNV GL. 

The DNV GL validation is seen as a major step towards the rapid commercialisation of the technology following two cooperation agreements that GTT signed with Hyundai Heavy Industries (HHI) and Samsung Heavy Industries (SHI) during 1H15.

The Mark V technology is an optimised version of the Mark III system and its sister Mark III Flex. It 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 said:  "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."
