French LNG containment systems specialist, GTT, has been assigned by two major companies to carry out front-end engineering design (FEED) studies on new gravity-based system (GBS) projects.
The first one, signed with a European EPC, concerns a large LNG liquefaction project comprising several concrete caissons with several liquid gas membrane tanks, while the second concerns a smaller and metallic GBS project conducted with an Asian partner for providing energy to an island.
For confidentiality purposes, the names of the contracting parties of the LNG projects cannot be disclosed, GTT said in its statement.
These two types of GBS are made of caissons consisting in concrete or metallic structures and membrane containment tanks using GTT technology. They lie on the seabed and can be installed in a port or isolated area and require limited additional infrastructure.
The FEEDs’ objectives are to develop GBS concept designs and to finalize economical and safe designs, including the production requirements adapted to the gravity-based structures specificities.
