Senegal-Mauritania GTA LNG project starts commercial phase

The Greater Tortue Ahmeyim (GTA) liquefied natural gas project off the coasts of Senegal and Mauritania has officially begun commercial operations, Enerdata reports. Golar LNG’s floating LNG unit, Gimi, which started production earlier in 2025, has now achieved commercial operations under a 20-year lease with BP, marking the end of its commissioning phase.

The facility has ramped up LNG production to about 2.4 million tonnes per year, roughly 90% of its nameplate capacity of 2.7 million tonnes. The project, operated by BP with a 56% stake, is its largest LNG venture and part of its broader push to expand upstream output, with ten new projects planned by 2027. Other partners include Kosmos Energy (27%), Senegal’s state oil firm Petrosen (10%), and Mauritania’s Société Mauritanienne Des Hydrocarbures (7%).

The GTA field, straddling both countries’ maritime boundaries, is expected to deliver regional energy security while supplying LNG to global markets.
