Baker Hughes, a GE company (BHGE), has been awarded a contract to supply turbomachinery equipment for the first phase of BP’s Greater Tortue Ahmeyim floating liquefied natural gas (FLNG) project located offshore Mauritania and Senegal, Africa. BHGE will provide the technology for four compressor trains for offshore gas liquefaction on board Golar LNG’s latest FLNG unit, Gimi, which is expected to begin production in 2022. The contract was awarded by Golar’s topsides contractor Black & Veatch (B&V).
Each of the four trains will consist of a PGT25+G4 aeroderivative gas turbine driving a GE 2BLC centrifugal compressor. This solution was designed, tested, and proven based on a model that B&V and BHGE developed together in 2015 as part of the Hilli FLNG conversion project, in which a liquified natural gas (LNG) carrier was converted into a floating liquefaction vessel. Golar’s FLNG vessel, Hilli Episeyo, was completed in 2018 and is currently in commercial operation offshore Cameroon.
FLNG Unit Gimi will liquefy gas as part of the first phase of the Greater Tortue Ahmeyim project and be located at a nearshore hub located on the Mauritania and Senegal maritime border. Gimi is designed to produce an average of approximately 2.7 million tons (2.5 million tonnes) of LNG per year using the B&V mixed refrigerant loop for natural gas liquefaction.
