Eni’s Tango FLNG is expected to go online offshore Republic of Congo in 2023, and the operator has signed a contract for a second FLNG unit for the Marine XII block. 

Wison Heavy Industry will construct and install the second FLNG unit, which will have a capacity of 2.4 million tonnes per annum (mtpa). The vessel will be 380 m long and 60 m wide and moored in 40 m water depth. It will be able to store 180,000 cubic meters of LNG and 45,000 cubic meters of LPGs. 

First steel on the cryogenic tanks was cut on Dec. 20, and long-lead items have been ordered. This unit is expected to bring overall LNG production capacity in Marine XII to over 3 mtpa, or over 4.5 Bcm/year in 2025. The Tango FLNG has a 0.6 mtpa capacity.

In August, Eni reported it acquired from the company Export LNG Ltd., which owned the Tango FLNG floating liquefaction facility. The Tango FLNG, built in 2017, has a treatment capacity of 3 MMcm/d and an LNG production capacity of about 1 Bcm/year. 

The units are both part of Eni’s Marine XII gas valorization plan. In April this year, Eni signed a framework agreement with the country to boost joint E&P operations and increase natural gas exports.
