McDermott International has bagged a fabrication subcontract, valued between $1m and $50m, for the Greater Tortue Ahmeyim project being developed by BP and its partners on the maritime border between Mauritania and Senegal.

The contract is related to the subsea production system (SPS) of the Tortue/Ahmeyim project, which holds an estimated 15 trillion cubic feet of gas.

Under the fabrication subcontract, McDermott will be responsible for project management, procurement, fabrication engineering, pre-assembly, fabrication, system-integration tests, and acceptance tests.

The engineering, procurement, construction and installation contractor (EPCI  contractor) is expected to begin work related to the fabrication contract during Q3 201. The work will be carried out at its Batam fabrication facility in Indonesia with a target to complete it by Q3 2020.

The Texas-based EPCI contractor is already engaged with the Greater Tortue Ahmeyim project having won the subsea equipment contracts in March 2019 in consortium with GE’s subsidiary Baker Hughes.

As part of the contract, McDermott is delivering EPCI of the subsea umbilicals, risers and flowlines (SURF), with its share of the contract being $500m-750m.

The EPCI contractor is using the Batam fabrication facility for executing fabrication of the pipeline structures and riser structure.

Commenting on the Greater Tortue Ahmeyim project contract, Ian Prescott – Senior Vice President for McDermott Asia Pacific, said: “This award reflects the value of holistic project planning to get the best outcomes for the project and the customer. Fabrication for both the SPS and subsea, umbilicals, risers and flowlines (SURF) scope for the Greater Tortue Ahmeyim project will now be undertaken in McDermott’s yard in Batam, which enables a fast-tracked fabrication schedule to be delivered.”

Partnering BP in the Greater Tortue Ahmeyim project are Kosmos Energy, Petrosen and SMHPM. Sanctioned in December 2018, the Greater Tortue Ahmeyim project is slated to begin production in 2020 by using an ultra-deepwater subsea system and a mid-water floating production, storage and offloading (FPSO) vessel.
