Gaztransport & Technigaz (GTT) has entered a technical assistance and licence agreement with China Merchants Heavy Industries-Jiangsu (CMHI-Jiangsu), a subsidiary of China Merchants Industry Holdings (CMI).

The agreement will allow the shipbuilder to use GTT’s membrane containment systems in the vessels it constructs.

The deal is said to mark a new stage in the alliance between the two firms, in part due to the shipyard having secured a licence to build large-capacity liquefied natural gas carriers (LNGCs).

CMI and GTT signed their first technical service agreement for the maintenance and repair of LNGCs in 2013.

In 2016, the firms reached a cooperation agreement for the assessment of CMHI to deploy GTT technologies.

GTT chairman and CEO Philippe Berterottière said: “We are honoured to carry on our collaboration with China Merchants Heavy Industries, one of the largest shipyards in China.

“We expect the new stage of this partnership to be a real success both in the LNG carrier construction and in the LNG fuelled market as the shipyard is renowned for its variety of vessels constructions.”

As the owner of seven shipbuilding and repair bases, CMI is a resource integration and management platform for China Merchants Group’s marine and offshore equipment manufacturing business.

Earlier this month, GTT won an order from Daewoo Shipbuilding & Marine Engineering (DSME) for the tank design of ten new LNG vessels.

The tanks will use the GTT-developed NO96 L03+ and NO96 GW membrane containment system.
