Congo LNG: the first project to export natural gas

The project will leverage Marine XII gas resources through two floating facilities offshore Congo.

Our strategy in the Republic of the Congo is centred around gas

The initiative aims to enhance gas resources, both associated and not, in the Marine XII concession by installing new facilities and optimising existing ones. This is part of our energy supply procurement diversification activities. By expanding the project, the Marine XII Joint Venture can increase its total production capacity from 1.9 to 3.0 MTPA of LNG. Eni commercialises 100% of the liquefied natural gas produced, going from 1.2 to 3.0 MTPA of volumes sold in the year (about 4.5 billion cubic metres of gas per annum). The facility will be the second FLNG to be set up in the Republic of Congo. The first is Tango FLNG (capacity of 0.6 MTPA), with LNG production scheduled to start in 2023. Both initiatives are part of the Marine XII development plan. The project has two stages:

  • Nearshore development with positioning of the Tango FLNG, the gas pre-treatment plant, installation of an additional platform and the drilling of 12 wells                                                        
  • Offshore development with positioning of the second FLNG, installation of 8 additional platforms and the drilling of 29 wells.

The gas produced will be liquefied using the two floating units owned by Floaters SpA.

Project development includes building onshore plants and facilities that enable, once work is finished, the processing of natural gas from the Marine XII Block.

Asset

Project configuration foresees the use of multiple technological and operational skills, needed to build an onshore pre-treatment plant, build and install both a separation and a compression platform, modify and build the platforms housing the 41 development wells to be drilled for the project, lay 10 sealines, install the Tango FLNG liquefaction barge (capacity 0.6 MTPA), install the Wison liquefaction plant (capacity 2.4 MTPA), implement all the accessory structures and activities needed to complete the project. The Congo FLNG ship, 380 metres long and 60 wide, will be anchored at a depth of around 40 metres and will be able to store more than 180,000 cubic metres of LNG and 45,000 cubic metres of LPG.

The impact on the environment and the community

This project has been developed with the circular economy in mind, using proprietary know-how and sharing the social and economic benefits of our activities with local suppliers.

Eni has never prospected for, or developed, hydrocarbons within the boundaries of natural sites included on the UNESCO World Heritage List. In May 2019, we formally pledged our commitment to this by officially recognising the biodiversity and ecosystem services (BES) policy that we were already following in our operations as part of our transformation process. We are committed to long-term investment, looking beyond short-term profit, both operationally and socially, as recognised in our new corporate mission statement inspired by the UN Sustainable Development Goals.

Safety first

Safety in the workplace is an imperative value we want to share with our employees, contractors and local stakeholders. We are committed to eliminate accidents and protect the integrity of our assets. We consolidate a culture of safety through management and organization models, digital tools and communication initiatives. Our goal is strengthening the awareness of our people and their sense of responsibility toward themselves and others, by expanding HSE tools and digitalization to make corporate processes safer, more efficient and faster.
