DNV GL approved Mark V technology

An optimised version of the Mark III system and its sister 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 is said to offer significant improvement of the warranted daily boil off rate.

“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,” said Philippe Berterottière, chairman and CEO, GTT. “This milestone will give shipowners further confidence in the performance of Mark V.”

The validation by DNV-GL is a major step towards commercialisation of the technology following two co-operation agreements signed earlier this year with shipbuilders Hyundai Heavy Industries and Samsung Heavy Industries.
