Mozambique’s Coral South project has has introduced the first hydrocarbons to the FLNG ‘Coral Sul’ from the Coral South reservoir offshore.
Eni, as upstream delegated operator of Area 4 on behalf of its partners ExxonMobil, CNPC, GALP, KOGAS and ENH, said that the FLNG will be ready to achieve its first LNG cargo in the second half of this year, which adds Mozambique to the list of LNG-producing countries.
Hydrocarbons introduction comes after the safe and timely conclusion of the offshore commissioning activities, Eni said. ‘Coral Sul’ arrived at her operating site offshore Mozambique in early January, 2022; mooring and connection to six underwater production wells were finalised in March and May 2022, respectively.
‘Coral Sul’ was brought into service with an energy optimisation approach integrated in the design via a systematic analysis of energy efficiency improvements.
These included among others, zero flaring during normal operations, use of thermal efficient aero-derivative gas turbines for refrigerant compressors and generation, use of dry low NOx technology to reduce NOx emission and waste heat recovery systems for the processing.
The FLNG is 432 m long and 66 m wide, weighs around 220,000 tonnes and has the capacity to accommodate up to 350 people in an eight-story living quarter module.
She is located at a water-depth of around 2,000 m and is kept in position by using 20 mooring lines that weigh a total of 9,000 tonnes.
‘Coral Sul’ has a gas liquefaction capacity of 3.4 mill tonnes per year and will put in production 450 bill cu m of gas from the giant Coral reservoir, located in the offshore Rovuma Basin.
