Coral South: the gas field off the coast of Mozambique

Coral South is the first project launched in the country's offshore that develops and produces significant hydrocarbon resources.

Development using a floating unit

Coral South was the first project approved by our Area 4 partners for developing gas resources discovered in the Rovuma Basin, off Mozambique’s coast. The project involves producing and selling gas from the southern part of the Coral field, using a floating plant for liquefying natural gas (LNG) with a capacity of 3.4 million tonnes. In 2016, we signed an agreement to sell 100 per cent of LNG production to British Petroleum (BP), and on 1 June 2017, we embarked on the start-up phase of the project, just three years after drilling the last test well. The liquefied gas is sold by us and other Area 4 concessionaires (including CNPC, Galp, Kogas, the Mozambican state company ENH and Exxon Mobil through its operator Mozambique Rovuma Venture S.p.A.) to BP, under a 20-year contract with an optional 10-year extension. 

The launch of the hull of the FLNG: photogallery

In January 2020, with our Area 4 partners in South Korea, we launched the hull for the Coral Sul Floating Liquefied Natural Gas (FLNG) treatment and liquefaction plant. It will extract 450 billion cubic metres of gas from the field. The hull is 432 metres long by 66 metres wide and weighs in at about 140,000 tonnes. The eight-storey living module, which will accommodate up to 350 people, has now been installed. All the main equipment is ready to be integrated, and we have started stacking the first deck. The plant will be the first ever FLNG built for deep waters and the first built specifically for Africa. In 2019, we began drilling and completing six subsea wells for feeding the liquefaction units. They will be drilled about 2,000 metres under water and have an average depth of about 3,000 metres.

The last topside module lifting: photogallery

In November 2020 we announced the lifting and installation of the last of the 13 topside modules of the Coral-Sul FLNG facility, currently under construction in South Korea. This lifting, which marks the end of the onshore-modules fabrication campaign configuring the entire gas treatment and liquefaction plant, is to schedule and in line with the expected sail-away in 2021 and gas production start-up in 2022.


Safety first

We regard safety at work as a core value – one we share with employees, contractors and local communities. That is why we do everything we can to avoid accidents, using organisational models to assess and manage risks, implementing training, developing expertise and promoting a culture of safety.


A floating unit for liquefying and exporting gas – and a real technological jewel – Coral Sul FLNG will be the first such on the African continent and the third in the world. Coral Sul FLNG will be 432 m long and 66 m wide, and weigh about 220,000 tonnes overall. The accommodation module will have eight floors with room for 350 people. It will be anchored about 2,000 meters deep, with the help of 20 lines weighing 9,000 tonnes combined. Construction of the main components began in 2018. Construction is taking place in seven working centres around the world.

Environment and community

The Coral South project involves us in local development, far wider than just the oil and gas sector. We have provided specialist training for more than 800 Mozambican workers, who will be employed in the project's operational phase. We are also committed to a huge programme of work for local communities, to improve their access to basic services such as education, clean water and health care, and support long-term, diversified, sustainable socio-economic growth.

Eni has never conducted oil and gas exploration and development activities within the boundaries of natural sites included on the UNESCO World Heritage List. In May 2019, we formally committed never to do so and officially instated a biodiversity and ecosystem services (BES) policy as part of our transformation journey. We are committed to long-term investment – looking beyond short-term profit to find ways to help create a more sustainable planet – as recognised in our new company mission, which is in turn inspired by the UN’s Sustainable Development Goals.
