LNG tank membrane partnership

The agreement includes the development and qualification of an innovative welding robot for the primary stainless steel and secondary invar membranes. This robot will permit the optimisation of the welding process and a reduction in construction time.

GTT’s Mark V technology is an optimised version of the Mark III and its sister Mark III Flex system and like them is also composed of a double insulation with reinforced polyurethane foam.

But the new system includes an innovative nickel-steel alloy corrugated secondary membrane and offers significant improvement of the warranted daily boil off rate. It has received Approval in Principal (AIP) from major classification societies.

GTT signed a similar partnership recently with Samsung Heavy Industries.
