BP has confirmed the development concept for the second phase of its Greater Tortue Ahmeyim (GTA) liquefied natural gas (LNG) project, which it operates and will, with its project partners offshore Mauritania and Senegal, take to the next stage of evaluation.
The partners will evaluate a gravity structure (GBS) as the basis for the GTA Phase 2 (GTA2) expansion project with a total capacity of between 2.5 and 3.0 million tonnes per year.
BP is the operator of the GTA project, with PETROSEN, Société Mauritanienne des Hydrocarbures (SMH) and Kosmos Energy as partners.
The GBS LNG developments have a static connection to the seabed, with the structure providing LNG storage and a foundation for the liquefaction facilities, BP said.
According to BP, the concept design will also include new subsea wells and equipment, integrating with and building on the existing GTA infrastructure.
In addition, the partnership will consider powering LNG liquefaction with electricity to help reduce operational emissions.
« BP et ses partenaires travaillent actuellement avec des sous-traitants pour faire progresser le concept vers le stade pré-FEED »,
said the company.
GTA is located 120 kilometres offshore in 2850 metres of water, one of the deepest underwater developments in Africa.
The first phase of the project is currently under development and will export gas to an FPSO about 40km offshore, where the gas will be processed and separated, before exporting the gas to floating LNG facilities 10km offshore. It is expected to produce around 2.3 million tonnes of LNG per year when operations start.
In October 2022, BP announced the signing of an exploration and production sharing contract for the BirAllah gas resource in Mauritania. In addition, BP continues to work with partners on the development of a major gas-to-power project in Senegal, Yakaar Teranga.
