Eni’s Nguya FLNG ready to start serving second phase of Congo LNG project

Italian energy firm Eni hosted on Tuesday the sail-away ceremony for the Nguya floating liquefied natural gas (FLNG) unit in Shanghai, China. The unit is ready to start serving the second phase of Eni's Congo LNG project.

Eni said in a statement that the ceremony was attended by Bruno Jean Richard Itoua, Minister of Hydrocarbons of the Republic of Congo, and Eni delegation led by Stefano Maione, director of development, operations and energy efficiency.

In November last year, China’s Wison New Energies launched the hull of Eni’s FLNG Nguya at its yard in Nantong, China.

WNE won a contract from Eni in December 2022 to build a 380-meter-long 2.4 mtpa FLNG and officially started work on the project in January 2023.

Last year, WNE also completed the installation of all four SPB LNG tanks and two LPG tanks on Eni’s Congo FLNG.

The FLNG will be able to store over 180,000 cubic meters of LNG.

WNE also incorporated Chart’s IPSMR liquefaction technology.

The unit is set to significantly boost LNG production as part of the Congo LNG project in the Marine XII concession, offshore the Republic of Congo.

It will be moored at a depth of 35 meters.

33 months

Conceived, designed, and built in only 33 months – from contract award to sail away – the FLNG sets a record for time-to-market in the entire sector, Eni claims.

Moreover, its technical features allow it to process gas from multiple fields, making it suitable for the development of future fields as well, Eni said.

Furthermore, the floating production and compression unit – formerly the Scarabeo 5 drilling rig – has been refurbished and will depart in the coming days.

It will be used to send processed gas to the Nguya unit.

According to Eni, work on the subsea infrastructure required to launch Phase 2 of the Congo LNG project is progressing on schedule, enabling mooring and startup by the end of 2025.

Tango FLNG, with a capacity of 0.6 mtpa, began production in December 2023 and has already exported 12 cargoes, Eni noted.

It will be joined by the Nguya FLNG by the end of the year, bringing the total capacity of the Congo LNG project to 3 mtpa, the Italian firm said.
