Subsea 7 has received a ‘substantial’ subsea services contract, from Beacon Offshore Energy , for the Shenandoah development in the Gulf of Mexico.

The project includes the subsea tie-back of four wells to the Shenandoah host facility, via a subsea manifold, with dual flowlines and risers.

Subsea 7 said that it defines a ‘substantial project’ as being valued between $150m and $300m.

Under the contract, Subsea 7 will be responsible for the engineering, procurement, construction, installation (EPIC), and commissioning of the subsea equipment.

The equipment include umbilicals, structures, and gas export and production flowlines.

Subsea 7 will also undertake the wet tow and hook-up of the semi-submersible floating production system (FPS) to the field, and install the mooring system.

The firm plans to undertake project management and engineering work immediately at its offices in Houston, Texas.

It plans to fabricate the flowlines and risers at the spoolbase in Ingleside, Texas, while the offshore operations will be conducted in 2024.

Subsea 7 US vice-president Craig Broussard said: “This project allows Subsea 7 to demonstrate the full capacity of our offering, including our extensive involvement in mooring and installation of host facilities, EPIC activities related to the flowline system, and utilising our industry-leading experience and welding capabilities to support the development of high-pressure fields.

“We look forward to building on the collaborative approach, demonstrated by the Shenandoah project, to form a long-term cooperative relationship in support of Beacon Offshore Energy’s future growth plans.”

Last year, Transocean was awarded a $252m contract for the newbuild ultra-deepwater drillship, dubbed Deepwater Atlas, for the Shenandoah project.

Discovered in 2009, Shenandoah is a conventional oil development field, located in water depths of up to 6,300 feet.

The field is owned by Beacon Offshore Energy Operating , Navitas Petroleum , BOE II Shen , and BOE II Exploration.
