Energy services provider Expro Group Holdings has announced a long-term production solutions contract with Eni Congo, a subsidiary of Italy’s Eni, for an LNG pretreatment facility in the Republic of Congo. The 10-year contract is expected to generate more than $300 million of revenue for Expro.

Expro will design, construct, operate, and maintain a fast-track onshore LNG pretreatment facility (OPT), part of the Marine XII development offshore Congo. The facility will be built near the Litchendjili gas plant, which supplies gas to the adjacent Centrale Electrique du Congo Pointe-Noire Power Plant and will enable the increase of LNG production from the West Africa area.

The OPT facility, designed to process approximately 80 MMcf/D of gas, will link to Eni Congo’s offshore floating LNG (FLNG).

At the end of last year, Eni signed a contract with Wison Heavy Industry for the construction and installation of a FLNG unit with a capacity of 2.4 mtpa destined for Congo.

The 380-m-long and 60-m-wide vessel will be anchored at a water depth of around 40 m and will be able to store over 180,000 m3 of LNG and 45,000 m3 of LPGs. Preliminary activities have already started, with long-lead items ordered.

It will be the second FLNG to be deployed in the Republic of Congo, the first one being Tango FLNG (0.6 mtpa capacity), with LNG production expected to begin in 2023. Eni purchased the company that owned the vessel from Exmar last August. Work is underway to build out the mooring and connection works necessary to tie in with the existing Marine XII network and infrastructure.

The addition of the second FLNG vessel will bring overall LNG production capacity on Marine XII to 3 mtpa in 2025.

Located about 20 km offshore, the Marine XII development holds an estimated 1.3 billion bbl of oil and 6 Tcf of natural gas, across a 571 km2 region.
