GTT is a technology and engineering group, specialised in cryogenic membrane containment systems used to transport and store liquefied gases, in particular LNG (Liquefied Natural Gas).

Thanks to its unique technologies and constant innovation efforts, the GTT Group is fully committed to global decarbonisation, particularly in the maritime and energy sectors.

OUR KEY FIGURES


750+

employees at end-december 2023 including 80% engineers and technicians


10%

of revenues are on average dedicated to innovation over the last ten years.


50%

of the technologies developed by GTT have made it possible to reduce the CO2 emissions of LNG carriers by nearly 50% since 2011.

60 YEARS OF PIONEERING TECHNOLOGY

Ever since the first membrane containment systems designed in the 1960s, the company’s flagship technologies, Mark and NO, which make it possible to safely and efficiently transport and store LNG at -163 degrees,  has never ceased to improve and to conquer new markets.

Thus, over the years, GTT has extended the application of its containment technologies to the fields of onshore storage tanks, offshore and multi-gas transport, as well as LNG vessel propulsion, for example.

The technologies offered by GTT combine operational efficiency with safety. Made using light and thin materials, the systems designed by GTT help to optimise storage capacity and reduce the construction and operational costs of vessels and tanks.

DECARBONISING THE MARITIME INDUSTRY

As the maritime industry decarbonises, GTT has adapted its membrane containment technology to meet the requirements of ship-owners who want to equip themselves with a LNG propulsion system, in particular to equip their merchant vessel fleets.

The Group is also proposing solutions dedicated to the entire logistics chain and bunkering operations.

For 60 years, GTT has also been actively working on the design of new technological and digital solutions to support ship-owners and energy providers to meet growing regulatory requirements and on the pathway to a decarbonised future, particularly through the green hydrogen and carbon capture.
