About us

GTT (Gaztransport & Technigaz) is an engineering company formed in 1994 by the merger of the two major players in the field of LNG (Liquefied Natural Gas) membrane containment systems: Gaztransport and S.N.Technigaz resulting in a cumulative experience of more than 60 years in the field of cryogenics and storage of liquefied gases.

GTT’s two main areas of expertise are cargo containment systems (CCS) for LNG carriers and land storage of LNG. LNG carriers and tanks designed with GTT containment systems have also been used to carry and store other liquefied gases (LPG, Ethlyene etc.).

GTT licences its technologies to world leading shipyards and EPCs for the construction of LNG carriers and land storage tanks.

The GTT systems are approved by all the major classification societies.

Its capacity range can go :
-for the floating: from 630m3 (Pythagore 1964) or more actual the US Barges for Wespac 2 200m3, up to the Qmax 266 000m3
-for the land storage: small capacity (under development for the CERN, to be filled with liquid argon), up to 200 000 m3 in Japan.

GTT obtained the ISO 9001-2008 certificate in December 2010 from Lloyd’s Register Quality Assurance.
