bp starts gas flow from GTA Phase 1 LNG project

bp PLC has begun flowing gas from wells at the Greater Tortue Ahmeyim (GTA) Phase 1 LNG development offshore Mauritania and Senegal, to its floating production storage and offloading (FPSO) vessel for the next stage of commissioning (OGJ Online, June 4, 2024).

One of the deepest offshore developments in Africa with gas wells in water depths of up to 2,850 m, GTA Phase 1—once fully commissioned—is expected to produce about 2.3 million tonnes/year (tpy) of LNG for more than 20 years, bp said.

Gas from GTA Phase 1 is being introduced to the GTA FPSO about 40 km offshore in a water depth of 120 m, where water, condensate, and impurities are removed. From there, it will be transferred via pipeline to a floating liquefied natural gas (FLNG) vessel 10 km offshore where it will be cryogenically cooled, liquefied, and stored before transfer to LNG carriers for export.

Some of the gas will be allocated to help meet growing energy demand in the two host countries, bp said.

The FPSO, which arrived offshore Mauritania and Senegal in second-quarter 2024, is designed to process over 500 MMscfd of gas.

bp operates GTA (56%) on behalf of partners Kosmos Energy (27%), Petrosen (10%), and SMH (7%).
