Eni SPA advanced work on its 3-million tonne/year (tpy) Congo LNG development with sail away of the Tango Floating Liquefied Natural Gas (FLNG) and Excalibur Floating Storage Unit (FSU) vessels from Dubai to Congo’s offshore. First phase startup of the project is expected in December 2023.
Tango FLNG, which has a liquefaction capacity of about 1 billion cu m/year (bcmy) of gas, will be moored 3 km offshore along with the Excalibur FSU vessel upon arrival in Congo. The Tango FLNG ship, 380 m long and 60 wide, will be anchored at a depth of around 40 m and will be able to store more than 180,000 cu m of LNG and 45,000 cu m of LPG.
Natural gas for the project will be supplied by Eni’s Marine XII 1.3-billion boe proven and probable reserves concession (65%), 20 km offshore Congo, and existing production infrastructure in a new, phased approach that will allow the full capacity of about 4.5 bcmy of gas liquefaction capacity at plateau, as well as zero routine flaring.
A second FLNG vessel with a capacity of about 3.5 bcmy of gas is under construction and will begin production in 2025.
According to the agreements recently signed, all LNG produced will be marketed by Eni.
The Congo LNG project is a joint venture of Eni, the Congolese National Oil Co. (SNPC), and TotalEnergies.
