GTT to design tanks for Arctic LNG 2 gravity-based structures

French LNG containment system specialist GTT has signed a contract with SAREN B.V. for detailed design and construction of three gravity-based structures (GBS) set for Novatek’s Arctic LNG 2 project.

SAREN, a Russian joint venture of Renaissance Heavy Industries Russia and Saipem, awarded a design, construction studies, and technical assistance for a membrane containment system of LNG and ethane tanks to be installed inside the three GBS.

GTT said that the first two GBS would consist of two LNG storage tanks of 114,500-cbm and one ethane storage tank of 980-cbm. The third one will only consist of two LNG storage tanks of 114,500-cbm.

The GBS terminals, which will sit on the seabed, are made up of concrete caissons with membrane containment tanks using GTT’s GST technology.

The units would be built in a dry dock of the Novatek-Murmansk LNG construction center. They will be towed and installed in their final location in the Gydan Peninsula in the Russian Arctic.

Philippe Berterottière, chairman and CEO of GTT, said: “This is GTT’s first project development in the GBS market. We are very confident in the perspectives of this solution and are looking forward to working on this project with our highly experienced partners to accompany them from an early stage and throughout all phases in this project for Novatek and its partners.“
