Mozambique's first cargo introduces East Africa as a new LNG export region Eni's Coral South floating liquified natural gas (FLNG) project offshore Mozambique has started up, with the first cargo leaving the Coral Sul liquefaction vessel in Area 4 - offshore Mozambique's northern Cabo Delgado Province - in mid-November. Start-up of the project (operated by Eni on behalf of its partners ExxonMobil, CNPC, GALP, KOGAS and ENH) adds Mozambique to list of global LNG-producing countries, and should eventually be transformational for the country's economy. Exports from the Coral South field are expected to be 3.4 million metric tonnes per annum (MMtpa), which will be purchased by BP under a 20-year contract with a 10-year extension clause, allowing for flexibility across global markets.

The deepwater Rovuma Basin will feed Coral South and subsequent LNG projects

Supergiant natural gas discoveries during the first three years of offshore exploratory campaigns in the Rovuma Basin in 2010-13 include the Prosperidade, Mamba and Golfinho/Atum field complexes. An estimated 12 trillion cubic feet (Tcf) of recoverable gas resources were discovered by Eni in the Coral field in 2012. At 2,000 m water depth, the Coral South project is the first FLNG facility to be deployed in deepwater offshore Africa and it is the deepest water FLNG production facility globally. Mozambique ranks third in Africa in terms of total recoverable gas resources, with 148 Tcf discovered within the Rovuma and Mozambique Basins (138 Tcf and 10 Tcf respectively), ultimately making up 14% of total recoverable gas discovered on the continent. At current resource estimates, Mozambique has the potential to export around 60 MMtpa of LNG once both Area 1 and Area 4 are fully developed.

Further north, prolonged negotiations in Tanzania have delayed a final investment decision (FID) on an onshore plant that would monetise deepwater gas discoveries made by Equinor and Shell. Twelve Tcf recoverable gas resides in Tanzania, with 10 Tcf still undeveloped offshore. Should discussions allow for a Host Government Agreement (HGA) on fiscal package and profit-sharing conditions by end-2022, a January 2025 target for FID would allow for around 10 MMtpa of Tanzanian LNG supplementing Mozambique's exports by 2030, boosting East Africa as a global gas supplier.

A second FLNG project could emerge in Area 4 amid onshore security challenges

Despite Mozambique's vast offshore gas reserves, production has been slow to materialize, and Mozambique's developing LNG sector is already being reshaped as domestic above-ground risks and global gas markets evolve. The offshore location of the Coral South FLNG project (Area 4) has mostly insulated it from the ongoing Islamist insurgency in Cabo Delgado province, which has stalled the development of larger onshore liquefaction projects fed by gas discoveries offshore Area 1 (TotalEnergies operated Mozambique LNG) and Area 4 (ExxonMobil and Eni operated Rovuma LNG). Coral South has taken eight years to reach first production since the final exploration well was drilled in 2014, but it remains well ahead of the onshore plants, which face ongoing delays mainly due to security concerns. First gas was sent to the Coral Sul FLNG unit in June this year after achieving FID in 2017. Eni and ExxonMobil therefore are reassessing how to monetize the 80 Tcf of gas reserves in offshore Area 4 more quickly, efficiently, and safely, with FLNG likely to take near-term priority over the still-unsanctioned Rovuma LNG onshore plant. Eni confirmed in late July that it is considering a new 2.5-3 MMtpa Area 4 FLNG project, as volumes in the Coral and Agulha fields may be sufficient to support the proposed new liquefaction vessel. Investors clearly are focused on monetizing proven resources over attempting to discover more gas in the basin. Mozambique's upstream regulator, the National Petroleum Institute (INP) has announced that no suitable bids were received for Rovuma Basin licenses on offer in Mozambique's 6th License round; whereas six blocks received successful bids from Eni (one license) and CNOOC (5 licenses) in the Angoche and northern Mozambique basins respectively.

FLNG offers pragmatic solution to project development challenges

FLNG technology offers Mozambique a near-term solution to gas monetisation amid security challenges, but it is still a relatively nascent technology, with uncertainty regarding project utilization rates, maintenance and operational costs in varying ultra-deepwater sea and weather conditions. It also offers little in terms of domestic employment or gas supply, marking a trade-off between domestic economic development and expediting revenue flows from exports. That said, for now FLNG remains the key enabler for Mozambique's Rovuma Basin gas monetization. The technology is increasingly quick to deploy and allows operators to largely circumvent certain above-ground risks. FLNG's ability to monetize both large resources and more marginal fields means it will be increasingly applied more widely across Africa, with additional projects planned in the Equatorial Guinea, Republic of the Congo, and Senegal.
