Italy’s Eni reports that it has begun installation works on the world’s first ultra-deepwater floating LNG (FLNG) vessel that will be moored in 2,000 m of water off of Mozambique in 2022
Coral Sul FLNG vessel is part of the Coral South project, which will produce 450Bn m3 of gas from the Coral reservoir. The hull is expected to be launched at South Korea’s Samsung Heavy Industries in 2020, in line with the planned production startup of the Coral South project in 2022.
The Coral Sul FLNG facility will have a gas liquefaction capacity of 3.4 mta when completed and will be the first ultra-deepwater FLNG vessel deployed offshore southeast Africa.
Anchored in 2,000 m of water by 20 mooring lines, the vessel, which will be 432 m long and 66 m wide, will house up to 350 people in its eight-story accommodation module.
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 project is expected to be 60% completed, reaching 10M production man hours.
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 3,000 m and will be drilled in 2,000 m of water. The activities, carried out by the Saipem 12000 drilling rig, will be completed by the end of 2020.
Eni has been present in Mozambique since 2006, with the acquisition of a participation interest in the exploration concession of Area 4, located offshore in the Rovuma basin, in the north of the country. Between 2011 and 2014, Eni discovered natural gas resources in the Coral, Mamba Complex and Agulha reservoirs, holding estimated 2,400Bn m3 of gas in place.
