For several years, South Korean shipbuilders have been designing their own systems in order to avoid paying hefty fees to the French company for any membrane LNG carrier orders they get.

The LNT A-BOX containment system, built by offshore veteran David Wu, is gaining traction in China, with Qatar, one of GTT's largest users, establishing closer relations with the Chinese upstart.

Qatar Petroleum, Qatargas, ConocoPhillips, ExxonMobil, Shell, and Total have started developing new medium and large LNG carrier designs in collaboration with LNT A-BOX, class society ABS, and Shanghai Waigaoqiao Shipbuilding.

A self-supporting prismatic IMO independent type A tank is put in an enclosed cargo hold with a complete secondary barrier in the LNT A-BOX containment system.

GTT's membrane containment systems dominated the market two decades ago, outperforming the previous successful Moss spherical designs.
