中国石化新闻网讯 据海上能源2月27日报道，总部位于英国的能源巨头英国石油公司(bp)及其合作伙伴已经确认了在毛里塔尼亚和塞内加尔海岸运营的Greater Tortue Ahmeyim (GTA)液化天然气(LNG)项目第二阶段的开发概念。
包括bp、PETROSEN、Société Mauritanienne des Hydrocarbures (SMH)和科斯莫斯能源公司(Kosmos Energy)在内的合作伙伴将评估一个基于重力的结构(GBS)，作为GTA第二阶段扩建项目(GTA2)的基础，年总产能在250万吨—300万吨之间。
据bp称，GBS液化天然气的开发与海底有静态连接，该海底结构提供液化天然气储存和液化设施的地基。
bp表示，该概念设计将包括新井和海底设备，整合并扩建现有的GTA基础设施，并补充道，该合作伙伴关系将考虑使用电力为液化天然气液化提供动力，以帮助降低运营排放。
该公司还证实，该伙伴关系目前正在与承包商合作，将这一概念推进到pre-FEED阶段。
bp负责运营和生产的执行副总裁Gordon Birrell表示，我们的目标是与我们的合作伙伴以及毛里塔尼亚和塞内加尔政府加强合作，以进一步在西非开发一个长期、成功的能源中心。GTA继续支持我们的战略，开发最具弹性的碳氢化合物，以帮助提供当今的能源安全。
GTA位于近海岸120公里，水深2850米处，是非洲最深的海底开发项目之一。
据bp称，目前正在开发的第一阶段将把天然气出口到离岸约40公里的浮式生产、储存和卸载(FPSO)船上，在那里天然气将被加工和液体分离，然后将天然气出口到离岸10公里的浮式液化天然气设施。
开始运营时，GTA预计每年生产约230万吨液化天然气。
2023年1月，Tortue FPSO开始向该项目地点进发。

BP’s GTA LNG project reaches new development stage
UK-headquartered energy major BP and partners have confirmed the development concept for the second phase of the BP-operated Greater Tortue Ahmeyim (GTA) liquefied natural gas (LNG) project off the coasts of Mauritania and Senegal.
The partnership, which includes BP, PETROSEN, Société Mauritanienne des Hydrocarbures (SMH), and Kosmos Energy, will evaluate a gravity-based structure (GBS) as the basis for the GTA Phase 2 expansion project (GTA2) with a total capacity of between 2.5-3.0 million tonnes per annum.
According to BP, GBS LNG developments have a static connection to the seabed with the structure providing LNG storage and a foundation for liquefication facilities.

In January 2023, the Tortue FPSO embarked on its journey towards the project site.
