BP has awarded contracts to OneSubsea, part of oilfield services firm Schlumberger, and Subsea 7 for the $9bn Mad Dog 2 deepwater development in the US Gulf of Mexico.
The Mad Dog Phase 2 project is the second stage of development of the BP-operated Mad Dog offshore field, which started production in 2005.
As part of the contract, OneSubsea will be responsible for engineering, procurement and construction (EPC) work of subsea production system of the project.
The scope of the contract includes subsea manifolds, trees, control system, single and multi-phase meters, water analysis sensors, intervention tooling and test equipment for producer and water injection wells associated with the project.
OneSubsea, Schlumberger, president Mike Garding said: “Our equipment reliability is a key factor in mitigating project risk and this project will benefit from the supplier-led approach of using standardized equipment designs and specifications.”
Additionally, Subsea 7 was selected to provide engineering, procurement, construction and installation work for subsea controls, flexible risers, pipeline systems, umbilicals and associated subsea architecture.
Subsea 7 Gulf of Mexico vice-president Craig Broussard said: “The Mad Dog 2 project is a significant award for Subsea 7. It combines Subsea 7’s capability with our Subsea Integration Alliance value offering to reduce risk and provide lower cost solutions for BP.
“This project serves as a step-change of how we work in the region and in Subsea 7’s ability to deliver superior value to the industry.”
Subsea 7 plans to commence offshore installation activities during 2019 and 2020.
The proposed Mad Dog Phase 2 development involves a new floating production platform with a production capacity of up to 140,000 gross barrels of crude oil per day from up to 14 production wells.
The project is operated by BP with 60.5% stake while other partners include BHP Billiton with 23.9%, Chevron affiliate Union Oil Company of California 15.6%.
