Bureau Veritas issues Design Approval for Mark V containment system

Leading classification society Bureau Veritas has issued Design Approval for the new Mark V LNG membrane containment system designed by France’s GTT. This clears the way for the system to be used in new LNG carriers and FLNGs.

The Mark V technology is an optimised version of GTT’s Mark III system. It is composed of double insulation with reinforced polyurethane foam. The new system also includes an innovative nickel-steel alloy corrugated secondary membrane and offers a significant improvement in the warranted daily boil off rate.

Jean-Francois Segretain, Technical Director, Bureau Veritas Marine & Offshore Division, says, “GTT’s Mark V system offers considerable benefits for new LNG projects and after rigorous examination we are very happy to award Design Approval to the system. GTT is the world leader in LNG containment and we have a long relationship with them. We look forward to working on the first newbuildings with the Mark V system.”
