bp PLC has received the floating production storage and offloading (FPSO) vessel for Greater Tortue Ahmeyim (GTA) Phase 1 LNG development.
The FPSO vessel has arrived at its destination on the maritime border of Mauritania and Senegal and is currently being moored at the site 40 km offshore in a water depth of 120 m.
The GTA Phase 1 development is expected to produce about 2.3 million tonnes/year (tpy) of LNG for more than 20 years. With wells in water depths of up to 2,850 m, GTA Phase 1 has the deepest subsea infrastructure in Africa and is the first gas development in this basin offshore Mauritania and Senegal.
The FPSO is expected to process over 500 MMscfd of gas. It will remove water, condensate, and impurities from the gas before transferring it via pipeline to the floating liquified natural gas (FLNG) vessel at the Hub Terminal about 10 km offshore. At the FLNG vessel, the gas will be cryogenically cooled, liquefied, and stored before being transferred to LNG carriers for export. Some will be allocated to help meet growing demand in the two host countries.
GTA is estimated to hold gas resources of 15 tcf. Phase 1 will export gas from four subsea wells to the FPSO, which will be operated by bp on behalf of project partners Kosmos Energy, Petrosen, and SMH. (OGJ Online, Aug. 7, 2023).
