Italian energy company Eni said it started installation work on the hull of the Coral South floating liquefied natural gas production plant to be deployed offshore Mozambique for start-up in 2022.
The FLNG hull is part of the Coral South project, which will put in production 450 billion cubic metres of natural gas from the giant Coral feed-gas reservoir.
The hull is expected to be launched in 2020 at the Samsung Heavy Industries shipyard at Geoje Island in South Korea where it is being constructed for the partners in the Eni Area 4 offshore resources licence in the Mozambican Rovuma Basin.
The Coral South FLNG facility will have a gas liquefaction capacity of 3.4 million tonnes per annum when completed and will be the second FLNG vessel to be deployed offshore Africa.
An FLNG project has been operational offshore Cameroon in West Africa since 2018 led by European energy firm Perenco and two further FLNG ventures are being developed off Mauritania and Senegal by BP of the UK and US company Kosmos Energy of Dallas, Texas.
The vessel, which will be 432 metres long and 66 metres wide and weigh about 220,000 tonnes, will house up to 350 personnel in its eight-storey accommodation module.
The facility will be anchored at a water-depth of around 2,000 metres by means of 20 mooring lines that weigh a combined 9,000 tonnes.
US major ExxonMobil has signed an agreement to acquire a 25 percent interest in Area 4 from ENI’s stake. The remaining interests in Area 4 are held by China National Petroleum Corp. (CNPC) through its exploration and development subsidiary CNODC (20 percent), Korea Gas Corp. (10 percent), Galp Energia of Portugal (10 percent) and Mozambique’s state-owned Empresa Nacional de Hidrocarbonetos (10 percent).
Construction works on Coral FLNG started in 2018 and is ongoing in seven operational centres across the world.
Construction of the mooring turret began in March and construction of the hull’s 24 modules that contain the LNG storage tanks and sections of the treatment facilities began in September in South Korea.
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 percent completion,” said Eni.
“Drilling and completion activities for the six subsea wells that will feed the liquefaction unit will begin in September 2019,” noted the Italian company.
“The wells will have an average depth of approximately 3000 metres and will be drilled in about 2000 metres of water depth,” stated Eni.
These activities are being carried out by the Italian-owned “Saipem 12000” drilling rig and 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,” said Eni.
