Gaztransport & Technigaz


Gaztransport & Technigaz SA is a French multinational naval engineering company with headquarters in Saint-Rémy-lès-Chevreuse, France.
Trading as the GTT Group, the company is an engineering organization specializing in membrane containment systems dedicated to the transport and storage of liquefied gas worldwide. GTT has developed and patented multiple solutions for the liquefied gas industry,
in particular for Liquefied Natural Gas.
The current company was established through a merger between rival companies Gaztransport SA and Technigaz SA in 1994.
On the 27 February 2014 the GTT Group was listed on the Euronext Paris stock exchange.

History

In the 1950s, European companies were looking for solutions to transport Algerian gas from the Sahara to Europe. The idea of a North African pipeline was scrapped due to regional instability at the time and this led to the first boom in the shipping of gas by sea in the form of a cryogenic liquid in LNG carriers.
After the Evian Accords in 1962, France purchased its first LNG carrier - the Jules Verne - for operation on the route between Oran and France. Great Britain already had two of these vessels at this time.
Both Gaztransport and Technigaz emerged as a result of the innovations taking place in this historical context.

Technigaz

In 1963 Gazocean, a company jointly owned by Gaz de France and NYK Line, created a subsidiary called Technigaz responsible for developing new LNG transportation technology. In 1964 Technigaz filed for a patent for "wallpanels for so-called membrane tanks" which was granted in 1968 and which led to the development of the Mark I containment system. Between 1968 and 1979, twelve LNG carriers were built using Technigaz Mark technology.
In 1983 Technigaz was sold to the Amrep Group which subsequently went bankrupt in 1984 and was itself taken over by the Bouygues Group. In 1994 Technigaz was merged with Gaztransport to create Gaztransport & Technigaz.

Gaztransport

Gaztransport was founded on the 10 January 1966. In 1967 Phillips Petroleum and Marathon Oil, which held contracts to import gas into Japan, placed an order for two LNG carriers, Polar Alaska and Arctic Tokyo, that were built in the Swedish shipyard of Kockums. These ships remained in operation for 45 years. In 1969 the Polar Alaska was launched, and between 1969 and 1978, ten LNG carriers used the NO systems developed by Gaztransport.
In 1994 Gaztransport was merged with Technigaz and Technigaz Shipping to create Gaztransport & Technigaz.

Technologies

In order to store and transport Liquefied Natural Gas an envelope or membrane system is required to separate the liquid gas at -163 °C from the ship's hull and to reduce evaporation.
GTT inherited the Mark and NO technologies from its founding companies and has since developed these technologies to their current forms.
In addition, GTT has developed a new technology specifically for the transportation of Liquefied Petroleum Gas called GTT MARS.
In April 2019 the National Institute of Industrial Property ranked GTT fourth in its leading companies list with 19 patents filed.

Singapore hub

In April 2019 GTT announced that it would be creating a "digital hub of excellence" in Singapore.
