FPSO sets sail for Greater Tortue Ahmeyim project
1/2/2023
The floating production, storage and offloading (FPSO) vessel for the Greater Tortue Ahmeyim (GTA) LNG project has started its journey towards the development site off the coasts of Mauritania and Senegal.
The FPSO set sail from Qidong, China, to travel 12,000 nautical miles via Singapore to its final destination in about 120 metres depth of water, around 40 km offshore on the maritime border of the neighbouring countries.
The vessel is a key part of the major integrated GTA development that also includes subsea development of gas fields and near-shore floating LNG (FLNG) facilities. The project’s first phase is set to produce around 2.3mn t/y of LNG and is due to be commissioned in 3Q2023. This will increase up to 10mn t/y under the second phase of development.
With eight processing and production modules, the FPSO will process around 500mn cf/d. The majority of the gas will be liquefied by the project’s FLNG facilities, enabling export to international markets. However, some will be allocated to help meet growing demand in the two host countries. Condensate will be periodically transferred from the FPSO to shuttle tankers for export to market.
GTA is the largest hydrocarbon development underway in the MSGBC (Mauritania, Senegal, the Gambia, Guinea-Bissau and Guinea-Conakry) region. The project is being jointly developed by operator BP; Kosmos Energy; Mauritania’s Ministry of Petroleum, Energy and Mines; Senegal’s Ministry of Petroleum and Energies; as well as Mauritania’s National Oil Company (NOC) SMHPM and Senegal’s NOC Petrosen. Technip Energies was awarded the engineering, procurement, construction, installation and commissioning contract.
The project will provide a long-term and viable supply of natural gas, opening up regional opportunities for power generation, industrialisation and revenue generation via exports. Up to 15tn cf of recoverable reserves will be maximised at a time when global stakeholders are looking to capitalise on African gas resources as markets transition away from Russian dependency and seek alternative supplies.
Meanwhile, Senegal’s pioneer oil development, the 100,000 b/d Sangomar project, is also set to see first production later this year. Its FPSO will be capable of producing some 100,000 b/d.
The success of both GTA and Sangomar are set to create a ripple effect of developments across the region, according to Energy Capital & Power, with a final investment decision (FID) soon expected for GTA’s neighbouring 13tn cf BirAllah project offshore Mauritania and Senegal’s 20tn cf Yakaar-Teranga project.
