Name of the Project
Coral South floating liquefied natural gas (FLNG) project.

In the deep waters of the Rovuma basin, which straddles Mozambique’s northern border with Tanzania, about 241 km north-east of Pemba and 48 km from the Mozambique coast.

Project Owner/s
Area 4 is operated by Mozambique Rovuma Venture (MRV), an incorporated joint venture (JV) owned by Eni, ExxonMobil and CNPC, which holds a 70% interest in the Area 4 exploration and production concession contract.

Eni is the offshore delegated operator and is leading the construction and operation of the FLNG facility on behalf of MRV.

Galp, KOGAS, and Empresa Nacional de Hidrocarbonetos EP each hold a 10% interest in Area 4.

Project Description
Coral South will be Mozambique’s LNG project and first FLNG facility ever deployed in the deep waters of the African continent.

The project is aimed at developing the southern part of the Coral (nonstraddling) reservoir, in the ultradeep waters of Rovuma basin Area 4.

The Coral natural gasfield contains about 450-billion cubic metres of gas. The first phase of the Coral field exploitation includes the development of five-trillion cubic feet of gas.

The project entails the engineering, procurement, construction, installation and commissioning (EPCIC) of an FLNG facility. Coral South FLNG will be the first of its kind in Africa and the third in the world.

The facility will be the first FLNG project for a deep-water gasfield at water depths of 2 000 m or more.

The facility will be 432 m long, 66 m wide, 38.5 m deep and weigh 220 000 t. It is designed to produce an estimated 3.4-million tons a year of liquefied natural gas (LNG) and 450 000 t/y of gas condensates (ultralight oil).

The FLNG will be a turret-moored, double-hull floating vessel on which gas-receiving, processing, liquefaction and offloading facilities will be mounted, together with LNG and condensate storage.

The FLNG is planned to consume 256 kWh/t LNG in the LNG liquefaction process, whereas the industry benchmark is typically 275 kWh/t to 400 kWh/t of LNG.

Potential Job Creation
The Coral South project will generate significant government income for the country while creating more than 800 new jobs during the operation period.

Capital Expenditure
Total development capital expenditure for upstream and midstream is estimated at $7-billion.

Planned Start/End Date
Coral-South announced a final investment decision in 2017. The construction of the FLNG hull and topside modules started in September 2019. The first LNG produced from the Coral gasfield was shipped from Coral South FLNG facility in November 2022.

Latest Developments
Air Products has announced that its dual mixed refrigerant LNG process technology and equipment, deployed at the Coral South FLNG plant, has successfully passed its performance test, achieving LNG production above 3.4-million tons a year.

Air Products’ proprietary AP-DMR LNG process was selected because of its high efficiency, reliable operation, and compact footprint. AP-DMR’s superior process efficiency combined with using aeroderivative machinery translates to a lower carbon intensity than all other LNG processes in floating service.

Key Contracts, Suppliers and Consultants
Main contractors:
TJS Consortium comprising TechnipFMC, TechnipEnergies, JGC and Samsung Heavy Industries (EPCIC of the FLNG, risers and flowlines and installation of the umbilical and subsea system); Aker (engineering, procurement and manufacturing of umbilicals); Baker Hughes (engineering, procurement and manufacturing of subsea production system, including wellheads, x-trees, manifolds and jumpers); Saipem (drilling and completion of the six subsea production wells performed by the Saipem 12000 rig); Matthews Daniel (marine warranty surveyor); and Lloyd’s Register (classification society).

KBR JV with Daewoo Shipbuilding & Marine Engineering Company (front-end engineering design); Baker Hughes and General Electric (rotating equipment for the power and gas refrigeration process of the new FLNG facility); SOFEC (engineering, procurement, and construction contract for the internal turret mooring system and its ancillary components); Air Products (cryogenic coil wound heat exchanger technology and the liquefaction process licence for the FLNG facility – AP-DMR); Norsafe (freefall systems containing gravity escape system, or GES, MKIII lifeboats with HD-50 davits and GES 45 lifeboats with HD-45 davits); Keppel Offshore & Marine (a turret mooring system); and Rina Services (certification authority for the design and fabrication of subsea structures and equipment, and to provide technological validation services for the FLNG).
