for the construction of membrane tank systems

Paris - December 3rd, 2019. GTT has signed a Technical Assistance and License Agreement (TALA) with the Chinese shipyard WISON Offshore & Marine (WOM) for the equipment of Floating Liquefied Natural Gas units (FLNG), Floating Storage and Regasification Units (FSRU), Floating Storage Regasification Power units (FSRP) and LNG Carriers, using GTT membrane solutions.

WOM is a pioneer in floating LNG in China, being the first in the world to deliver barge-based FLNG and FSRU on a turn-key basis. WOM obtained its GTT license after having successfully completed a qualification process that began earlier this year, including the construction of Mark IIItechnology Mock- up.

This agreement will enable both partners to further expand their offer to ship-owners, to target new markets, especially focusing on floating based solutions, and to advance the development of LNG in the global supply chain.

Mr. An Wenxin, President and Chief Operating Officer of WISON Offshore & Marine, said at this occasion: "We are very proud to be licensed by GTT for Membrane technologies. This will allow us to offer more actively LNG solutions with GTT's technologies in China, which is what the market is asking for."
