Beacon Offshore lets EPIC contract for Shenandoah development
Beacon Offshore Energy LLC has let a contract to Subsea 7 SA for subsea installation services for the Shenandoah development offshore Gulf of Mexico in water depths up to 6,300 ft.
Shenandoah lies 160 miles off the coast of Louisiana in Walker Ridge Blocks 51, 52, and 53 (OGJ Online, Aug. 26, 2021). It is expected to come online as early as late 2024. Multiple wells are expected to develop an estimated 100-400 million bbl, targeting previously discovered oil-bearing Upper and Lower Wilcox reservoirs.
The project covers the tie-back of four subsea wells to the Shenandoah host infrastructure through a subsea manifold with dual flowlines and risers.
The work scope, valued at $150-300 million by the service provider, includes engineering, procurement, construction, installation (EPIC) and commissioning of the subsea equipment including structures, umbilicals, and production and gas export flowlines.
Subsea 7’s scope also includes the wet tow and hook-up of the semi-submersible FPS to the field and mooring system installation.
Project management and engineering will begin immediately at Subsea 7’s offices in Houston, Tex. Fabrication of flowlines and risers will take place at Subsea 7’s spoolbase in Ingleside, Tex., with offshore operations scheduled for 2024.
