The flagship Grand Tortue Ahmeyim (GTA) liquefied natural gas project, located on the maritime border between Mauritania and Senegal, is confirming its potential with solid operational performance in 2025 and ambitious growth prospects. According to the latest information published by operator Kosmos Energy Ltd, the project delivered 18.5 gross LNG cargoes and one condensate cargo over the past year. Importantly, Kosmos announces that delivered volumes are expected to nearly double in 2026, a projection that underscores the upward momentum of this strategic offshore field.
This growth builds on the continued progress of Phase 1 of the project. Production increased throughout the third quarter of 2025 to reach an average of approximately 11,400 net barrels of oil equivalent per day. The FLNG facility reached its nominal capacity of 2.7 million tonnes per annum in December 2025, with production peaks approaching 3 million tonnes. At the same time, the partnership is firmly committed to a cost rationalisation programme, having already reduced its net operating costs by approximately £10 million quarter-on-quarter. Additional measures are underway, including the refinancing of the FPSO lease agreement, which is expected to be completed by the end of 2025, and the implementation of a lower-cost operating model.
Attention is now turning to the future and the next phase of development, known as Phase 1+. Presented as a low-cost extension of existing facilities, this phase aims to approximately double gas throughput by 2029 by leveraging the infrastructure already in place. With LNG volumes in the GTA set to double as early as next year, this project confirms its increasingly central role in global energy supply and marks a major milestone for the West African gas sector.
