GTT, a provider of containment systems, has secured an order to provide its Mark III Flex membrane technology for two new liquefied natural gas (LNGC) carriers to be built by South Korean shipbuilding company Hyundai Heavy Industries (HHI).

To be built at HHI’s shipyard in Ulsan, the new vessels are scheduled for delivery in 2019 to South Korean ship-owner SK Shipping.

The new vessels are designed according to the latest IGC standards published in 2016.

Under the deal, the carriers will be equipped with Mark III Flex technology, which is specially suitable for the XDF propulsion system installed on SK Shipping’s LNG carriers.

GTT chairman and CEO Philippe Berterottière said: "GTT is very pleased to continue our collaboration with HHI.

"This new contract demonstrates HHI’s confidence in GTT technologies which already equip some fifty LNG carriers in service built by the shipyard.

"SK Shipping has been using vessels equipped with GTT membranes for some time, and we are very committed to this excellent partnership."

Since 2011, over 60 LNG carriers across the world have been equipped with Mark III Flex technology, of which 34 are currently in service.

By improving the design and components of its Mark range, GTT has been able to provide insulation solutions that offer increased performance adapted to the requirements of the new vessel propulsion systems, which are more fuel efficient.

The improvement has also helped GTT to provide new projects that require greater resistance to liquid motion, particularly for multi-gas applications, or partially filled tanks such as FSRUs and FLNGs.

In October last year, GTT received an order for two LNG carriers that would be built by Daewoo Shipbuilding & Marine Engineering (DSME).

To be operated by BW Group, the vessels are scheduled to be delivered in 2018 and 2019, while they will be equipped with GTT’s NO96 GW technology, which allows an optimised boil-off rate of LNG cargo.
