Gaztransport & Technigaz (GTT) is a France-based engineering and technology company specializing in the containment and transportation of liquefied gases. The company develops membrane containment systems that allow liquefied natural gas (LNG) and other cryogenic gases to be stored and transported safely at very low temperatures.
GTT’s technologies are used primarily in LNG carriers, floating storage and regasification units, floating liquefied natural gas facilities, and other vessels designed to handle liquefied gases. Its principal membrane systems include the Mark III technology, associated with Technigaz, and the NO96 technology, associated with Gaztransport. The company also provides engineering, technical assistance, maintenance, inspection, training, and related services to shipyards, vessel owners, and energy companies.
GTT was formed through the combination of Gaztransport and Technigaz, two companies with roots in the development of specialized LNG containment technologies in France. Based in Saint-Rémy-lès-Chevreuse, France, the company serves an international customer base through its relationships with shipyards and energy-industry participants around the world. In addition to LNG applications, GTT has pursued technologies for other liquefied gases and lower-carbon energy applications, including hydrogen and carbon dioxide.
