英国石油公司 (BP) 2 月 15 日宣布，将为英国石油公司运营的耗资数十亿美元的 Greater Tortue Ahmeyim (GTA) 液化天然气项目提供服务的 Gimi 浮式液化天然气 (FLNG) 船已抵达毛里塔尼亚和塞内加尔海上边界现场。

继 2023 年推迟后，预计于今年晚些时候启动。

GTA 第一阶段的产量预计为每年约 230 万吨 (mtpa)。英国石油公司表示，该项目预计将生产液化天然气超过20年，并使毛里塔尼亚和塞内加尔成为全球液化天然气中心。

GTA 一期开发项目的油井水深达 2850 m，拥有非洲最深的海底基础设施。GTA 第二阶段正在设计中。

GTA 一期项目将从离岸约 120 公里的深水储层中生产天然气，通过海底系统输送到现场的 FPSO。该容器最初将处理气体以去除较重的碳氢化合物成分。

然后，天然气将通过管道输送至位于 GTA 枢纽的 Gimi FLNG，并在船上的四个液化装置中进行低温冷却，并在转移至液化天然气运输船之前进行储存。Gimi 最多可储存 125,000 立方米。立方米液化天然气。

Gimi 由Golar LNG 公司拥有和运营，于 2023 年 11 月从新加坡起航，航行 9,000 海里到达 GTA 现场。Golar LNG宣布该船于一月份抵达现场。

BP 代表合作伙伴Kosmos Energy运营该项目，持有 56% 的权益，持有 27% 的权益，Petrosen持有 10% 的权益，SMH 持有 7% 的权益。

The Gimi floating LNG (FLNG) vessel that will serve the BP-operated multibillion-dollar Greater Tortue Ahmeyim (GTA) LNG project has arrived on site on the Mauritania and Senegal maritime border, BP announced Feb. 15.

Start-up is slated for later this year, after being delayed in 2023.

GTA Phase 1 is set to produce around 2.3 million tonnes per annum (mtpa). The project is expected to produce LNG for more than 20 years and enable Mauritania and Senegal to become a global LNG hub, BP said.

With wells located in water depths of up to 2850 m, the GTA Phase 1 development has some of the deepest subsea infrastructure in Africa. GTA Phase 2 is being designed.

The GTA Phase 1 project will produce gas from reservoirs in deep water, approximately 120 km offshore, through a subsea system to an FPSO already on site. The vessel will initially process the gas to remove heavier hydrocarbon components.

Gas will then be transported by pipeline to the Gimi FLNG at the GTA Hub, where it will be cryogenically cooled in the vessel’s four liquefaction trains and stored before transfer to LNG carriers. Gimi can store up to 125,000 cu. m of LNG.

Gimi, owned and operated by Golar LNG, set sail from Singapore in November 2023 and travelled 9,000 nautical miles to the GTA site. Golar LNG announced the vessel’s arrival on site in January.

BP operates the project with 56% interest on behalf of partners Kosmos Energy with 27% interest, Petrosen with 10% and SMH with 7%.
