Baker Hughes Wins Second Contract on Greater Tortue

May 6, 2019

Baker Hughes, a GE company, has been awarded a contract to supply turbomachinery equipment for the first phase of its Greater Tortue Ahmeyim floating liquefied natural gas (FLNG) project offshore Mauritania and Senegal. 

BHGE will provide the technology for four compressor trains for offshore gas liquefaction on board Golar LNG’s FLNG solution, expected to deliver 2.5 million tonnes of LNG per annum.

The Greater Tortue Ahmeyim project will produce gas from an ultra-deepwater subsea system and mid-water floating production, storage and offloading (FPSO) vessel, which will process the gas and remove heavier hydrocarbon components. The gas will then be transferred to a floating liquefied natural gas (FLNG) facility at a nearshore hub located on the Mauritania and Senegal maritime border. 

The FLNG facility is designed to provide circa 2.5 million tonnes of LNG per annum on average, with the total gas resources in the field estimated to be around 15 trillion cubic feet. The project, the first major gas development to reach final investment decision in the basin, is planned to provide LNG for global export as well as  making gas available for domestic use in both Mauritania and Senegal.

The initial subsea infrastructure at the project will connect the first four of 12 wells consolidated through production pipelines leading to the FPSO. From the FPSO, liquids will be removed and the export gas transported via a pipeline to a FLNG hub terminal where the gas will be liquefied.

The contract was awarded to BHGE in Q1 by Golar’s topsides contractor, Black and Veatch (B&V). The award builds on a separate subsea production contract also received by BHGE in the first quarter for the project.

Each of the four trains will consist of a PGT25+G4 aeroderivative gas turbine driving a centrifugal compressor. This solution was designed, tested and proven based on a model that B&V and BHGE developed together previously for a similar application. The gas turbines and compressors will be manufactured, tested and transported from BHGE’s plants in Italy.

Rod Christie, President and CEO of BHGE Turbomachinery & Process Solutions says, “Our technology solution has been proven to support FLNG, is based on a strong partnership with B&V and offers best-in-class reliability rates that will help reduce operational risks for Golar and BP.

The PGT25+ G4 gas turbine family has more than 560 units in operation, with more than 3.7 million of fired hours of operating experience. First introduced in the mid-2000s, the PGT25+ G4 builds on the LM2500 and PGT25 heritage, which has over 2500 engines in service and has accumulated more than 94 million hours of operation with best-in-class reliability and availability.
