GTT to provide Mark III cryogenic membrane technology to Hyundai Heavy Industries


French marine engineering company Gaztransport & Technigaz's (GTT) has received an order to provide a cryogenic membrane containment system to South Korean shipbuilder Hyundai Heavy Industries (HHI).

The order requires GTT to equip HHI's new floating storage and regasification unit (FSRU) with its Mark III cryogenic membrane containment system.

GTT chairman and CEO Philippe Berterottière said: “GTT notes that the performance of its technologies for the FSRU market is both renowned and appreciated by the key players of the offshore industry.

“HHI is a long term partner, and we are both involved to make the maritime industry progress by providing safe and flexible solutions.”

GTT states the 170,000m³ FSRU will be built on behalf of a European shipowner at Hyundai's shipyard in Ulsan, South Korea.

"GTT notes that the performance of its technologies for the FSRU market is both renowned and appreciated by the key players of the offshore industry."

The vessel will also be equipped with a Dual Fuel Diesel Engine motorisation, as found in standard LNG Carriers (LNGC).

Delivery of the containment system is expected to take place in March 2019.

GTT's Mark III membrane system comprises a primary metallic membrane positioned on top of a prefabricated insulation panel, including a complete secondary membrane.

The primary membrane is constructed out of corrugated stainless steel and contains the LNG cargo and is directly supported by and fixed to the insulation system.

The secondary membrane is made of Triplex, and is placed inside the prefabricated insulation panels between the two insulation layers.

Mark III's cryogenic liner is directly supported by the ship’s inner hull.
