European Contractor Steps into Complete BP Gas Project After McDermott's Early Exit

European offshore contractor Allseas has been awarded a contract to complete the subsea pipelaying work on BP’s Greater TortueAhmeyim (GTA) natural gas project offshore Mauritania and Senegal, following the early departure of US contractor McDermott International.

McDermott left the project in September 2023, with the workscope about 80% complete, amid a legal and payment dispute with BP about how the six-month force majeure on GTA in 2020 impacted its original contract.

Allseas will undertake GTA offshore pipelay works starting early December 2023 using the world’s largest construction vessel, the Pioneering Spirit. Installation support will be provided by Allseas’ offshore construction support vessel Oceanic.

The GTA project encompasses a floating production, storage, and offloading vessel (FPSO) where gas and liquids will be separated. The liquids will be exported by shuttle tanker, with gas being sent via a pipeline to Golar LNG’s 2.3 million tonnes per annum (MTPA) floating liquefied natural gas (FLNG) vessel Gimi.

The project is expected to produce 2.5 MTPA of LNG and 0.6 MTPA of natural gas liquids (NGLs) at peak capacity. The first gas is expected in 2023.

The GTA project is a major development for Mauritania and Senegal and is expected to provide significant economic benefits for both countries. The project is also expected to reduce Europe’s reliance on Russian gas.
