  埃尼集团已开始在将停泊在莫桑比克近海的珊瑚苏尔浮式液化天然气(Flng)处理和液化装置的船体上进行安装工程。该装置是珊瑚南部项目的一部分,该项目将从巨大的珊瑚储层中生产4500亿立方米的天然气。该船体预计将于2020年完工,计划于2022年启动的珊瑚南部项目的生产。

  Coral Sul-Flng设施建成后,天然气液化能力将达到340万吨/年,并将成为非洲大陆深水区首次部署Flng船舶。该船长432米,宽66米,重约220万吨,可容纳多达350人的八层住宿舱。该设施将通过20根总重量为9000 t的系泊缆在水深约2000 m处进行锚定。

  Coral Sul Flng的施工工程始于2018年,在全球七个地方进行模块加工。3月开始建造系泊炮塔;9月开始安装包含液化天然气储罐和处理设施部分的船体24个模块。上部结构及生活区包括12个天然气处理和液化天然气模块,从去年11月开始建造。到2019年底,项目总进度预计将超过60%,总工时预计将达到1000万。

  为液化装置提供原料的六口海底油井的钻井和完井活动将于2019年9月开始。这些井的平均深度约为3000 m,将在约2000 m的水深范围内钻取。SAIPEM 12000钻机将于2020年底完成这些活动。

  除了正在建设的液化天然气基础设施外,Coral South项目还包括一些旨在提高当地劳动力整体能力的举措。其中包括为800多名莫桑比克人开展的专门培训活动,这些人最终将在项目的运营阶段被雇用。埃尼集团还参与了一个广泛的社会、经济和卫生保健计划,以支持当地社区的长期、多样化和可持续发展。

  埃尼集团自2006年以来一直驻扎在莫桑比克,收购了位于莫桑比克北部罗伏马盆地深海近海的4号勘探特许权的参与权益。2011年至2014年期间,埃尼集团在珊瑚、曼巴综合体和阿古拉储层发现了超大型天然气资源,储量估计为24000亿立方米。

  Eni has started installation works on the hull of the Coral Sul floating LNG (FLNG) treatment and liquefaction unit that will be moored offshore in Mozambique. The unit is part of the Coral South project, which will put in production 450 billion m3 of gas from the giant Coral reservoir. The hull is expected to be launched in 2020, in line with the planned production start-up of the Coral South Project in 2022.

  The Coral Sul FLNG facility will have a gas liquefaction capacity of 3.4 million tpy when completed and will be the first FLNG vessel ever to be deployed in the deep waters of the African continent. The vessel, which will be 432 m long and 66 m wide and weigh about 220 000 t, will be able to house up to 350 people in its eight-storey accommodation module. The facility will be anchored at a water-depth of around 2000 m by means of 20 mooring lines that weigh a combined 9000 t.

  Construction works on the Coral Sul FLNG started in 2018 and are ongoing in seven operational centres across the world. Construction of the mooring turret began in March; construction of the hull’s 24 modules that contain the LNG storage tanks and sections of the treatment facilities began in September. Construction of the topside, consisting of 12 gas treatment and LNG modules, started last November, along with the living-quarters. By the end of 2019 the overall progress of the project is expected to exceed 60% completion with the total man-hours worked shortly expected to reach 10 million.

  Drilling and completion activities for the six subsea wells that will feed the liquefaction unit will begin in September 2019. The wells will have an average depth of approximately 3000 m and will be drilled in about 2000 m of water depth. The activities, carried out by the SAIPEM 12000 drilling rig, will be completed by the end of 2020.

  Alongside the LNG infrastructure under construction, the Coral South project also includes a number of initiatives aimed at enhancing the overall capabilities of the local workforce. These include specialised training activities for over 800 Mozambicans, who will eventually be employed during the operational phase of the project. Eni is also engaged in a broad programme of social, economic and health care initiatives, to support a long-term, diversified and sustainable development of the local communities.

  Eni has been present in Mozambique since 2006, with the acquisition of a participation interest in the exploration concession of Area 4, located in the deep offshore in the Rovuma basin, in the north of the country. Between 2011 and 2014, Eni discovered supergiant natural gas resources in the Coral, Mamba Complex and Agulha reservoirs, holding estimated 2400 billion m3 of gas in place.
