Tractebel, which is also part of Engie, said in a statement that the contract award follows a competitive tender process involving several French and international engineering firms.
The company has been mandated to carry out the feasibility studies for the Sorbet project and the detailed engineering studies for the Noemic2 project.
Tractebel said the Sorbet gas project is a “major” environmental and operational upgrade at the Fos Cavaou LNG terminal.
It is designed to reduce gas flares by capturing and compressing high-pressure boil-off gas for reinjection into the national gas network (NaTran).
On the other hand, Noemic2 aims to automate the propane injection process introduced in 2023 as part of the Noemic project.
Like Sorbet, this project seeks to reduce flaring during prolonged shutdowns of the terminal.
Noemic represents the temporary mitigation phase, while Sorbet is the long-term solution, with commissioning planned for late 2029, according to Tractebel.
This project supports Tractebel, Elengy, and Engie’s decarbonization objectives by reducing CO2 emissions by minimizing the volume of gas burned during operational phases, the company said.
Tractebel did not provide the financial details.
Elengy operates the Fos Cavaou facility and the Fos Tonkin facility on the Mediterranean coast. It also operates the Montoir-de-Bretagne facility on the Atlantic coast.
These terminals have a combined regasification capacity of some 21.5 bcm per year.
In addition to these three facilities, France also has the Dunkirk onshore LNG terminal.
