French engineering and technology company Gaztransport and Technigaz, has signed an agreement for the design and construction of two LNG carriers to be built by Japan’s Imabari Shipbuilding.

The vessels will be equipped with GTT’s Mark III Flex containment system and will include a new MEGI propulsion system.

They will be operated by Spanish shipowner Elcano, which has a long history of operating GTT-designed LNG carriers. Delivery is scheduled for 2017.

Elsewhere, the company has also received approval in principle from DNV GL for the design of a 2,200 cubic metre LNG bunker barge. The design incorporates GTT’s membrane Cargo Containment System (CCS), which is used in around 70% of the global LNG carrier fleet and nearly 90% of LNG carrier projects on order.

“This Approval in Principle from DNV GL is a major step forward in demonstrating the suitability of the GTT membrane systems for LNG storage and transportation within North American waters. The robust and highly competitive GTT solutions for the North American market complement the on-going price quotation with local shipyards” said Aziz Bamik, general manager, GTT NA. 

“The GTT membrane system provides more choice than just the Type C tank containment systems. It allows for better volumetric efficiency, which is a concern for ship types where sacrificing revenue earning space for bunker is often a show-stopper,” added Tony Teo, DNV GL’s Houston-based technology and business director.

The CCS selected for the barge is GTT’s proprietary Mark III Flex system, an enhancement of the Mark III system that allows for improved thermal and structural performance of the CCS. The Mark III membrane CCS consists of a cryogenic liner directly supported by the vessel’s inner hull, which allows for maximum volumetric utilisation of the available cargo space. This liner is composed of a primary metallic membrane fastened atop a prefabricated insulation panel that includes a complete secondary membrane.
