McDermott scores additional Greater Tortue Ahmeyim job

McDermott International has been awarded a new fabrication subcontract for the Greater Tortue Ahmeyim natural gas project offshore Mauritania and Senegal.

“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,” said Ian Prescott, senior vice president for Asia Pacific.

The scope of work for the fabrication of the SPS includes project management, fabrication engineering, procurement, pre-assembly, fabrication, acceptance tests, and system-integration tests.

The work is scheduled to begin in the third quarter of 2019 and is expected to be completed by the third quarter of 2020 in McDermott’s fabrication facility in Batam, Indonesia.

As part of a previous award, McDermott is also fabricating the pipeline structures and riser structure for the Greater Tortue Ahmeyim project in Batam.

It is worth reminding that BP reached the final investment decision for the Greater Tortue Ahmeyim field in December of last year.

The Greater Tortue Ahmeyim project located at the maritime border of Senegal and Mauritania has been sanctioned by BP and its partner Kosmos Energy in December last year.

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, removing heavier hydrocarbon components. The gas will then be transferred to a floating liquefied natural gas (FLNG) facility at a nearshore hub.

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, with first gas expected in 2022.

BP Gas Marketing has been selected as the sole buyer for the investor partners’ LNG offtake for Tortue Phase 1.
