据8月28日Offshore Energy报道称，麦克德莫特公司（McDermott）已经与尼克森公司（Nexans）签署了一份合同，为英国石油公司位于毛里塔尼亚和塞内加尔近海的Greater Tortue Ahmeyim天然气项目提供大约100公里的海底脐带缆和配件。
此前，麦克德莫特和贝克休斯去年3月被任命为该天然气项目的海底封隔器、立管和流水线以及海底生产系统设备的交付负责人。
Nexans周三表示，根据与麦克德莫特的合同条款，它将为辅助硬件提供管理、采购、工程、制造和测试活动。电缆和光纤将在罗南的尼克森挪威工厂生产，脐部零件将在哈尔登的尼克森挪威专业工厂开发、生产和测试，将于2021年完成交付。
Nexans负责海底和陆地系统的高级执行副总裁文森特•德萨尔(Vincent Dessale)表示，这份合同对于Nexans保持在西非地区的市场地位，以及作为一个新的超深水天然气开发项目的一部分，具有重要的战略意义。
Tortue油田位于毛里塔尼亚海岸外约120公里处，横跨海上边界，水深2850米。海底系统包括4口第一口天然气井，集中在一个钻井中心。
该生产系统与位于大陆架边缘、水深100-120米的一个扩张式系泊FPSO装置相连，距离约70公里。FPSO对天然气进行预处理，然后将天然气出口到35公里外的近海枢纽和码头设施，将天然气被液化并卸给液化天然气运输船。

Nexans to supply umbilicals for BP’s greater Tortue Ahmeyim project
McDermott has awarded a contract to Nexans for the supply of approximately 100 km subsea umbilicals and accessories for BP’s Greater Tortue Ahmeyim natural gas project offshore Mauritania and Senegal.
It is worth reminding that McDermott, together with Baker Hughes, was last March put in charge of delivering subsea umbilicals, risers and flowlines and subsea production system equipment for the Greater Tortue Ahmeyim natural gas project.
Nexans said in a statement The electrical cables and fiber optics will be manufactured at Nexans Norway plant in Rognan and the umbilicals will be developed, manufactured and tested at Nexans Norway specialized plant in Halden. The delivery will take place in 2021, Nexans said.
Vincent Dessale, Senior Executive Vice President for Subsea and Land Systems at Nexans said: “The Greater Tortue Ahmeyim contract is of strategic importance to Nexans in maintaining a market position in the West African region as well as being a part of a new, ultra-deepwater gas development.”
The Tortue field is located approximately 120 km offshore the coast of Mauritania and Senegal straddling the maritime border, in 2,850 m water depth. The subsea system includes a total of 4 wells at first gas, clustered at The production system ties back approximately 70 km to a spread moored FPSO unit positioned at the shelf edge in 100-120 m water depth. The FPSO undertakes gas pre-treatment before exporting the gas 35 km to a nearshore hub and terminal facility where the gas is liquefied and offloaded to LNG carriers.
