Lloyd’s Register approves GTT’s Mark V technology


Paris – 12 October. 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 earned a General Approval from the classification society Lloyd’s Register. This is the second validation for GTT’s latest technology, after Mark V was recently granted a similar General Approval from DNV-GL.

The Mark V technology was developed after a number of years of research and development. It 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.

Tom Boardley, Lloyd’s Register’s Marine Director said: “This is important news and we are very pleased to have been working with GTT in the ongoing development of their innovative gas containments systems.” Philippe Berterottière, Chairman and CEO of GTT declared: “This new milestone in the development of the Mark V system demonstrates the quality of GTT innovation as well as the close relationship established with class and particularly with Lloyd’s Register.”
