ABERDEEN, UK –Chevron North Sea has awarded more than £550 million ($843.5 million) in contracts for capital projects at Alder and Rosebank in the UK North Sea.
The subsea equipment vendor contract for Rosebank goes to OneSubsea UK. The contract includes the engineering, supply, and manufacturing of subsea manifolds, subsea trees, and subsea control systems.
Three contracts have been awarded for theAlder project, also to UK vendors:
1. Detailed engineering, procurement, installation, and commissioning of the complete subsea system, including the main subsea manifold, subsea isolation valve manifold, 28 km (17 mi) of pipe-in-pipe flowline, umbilical and tie-in spools, awarded to Technip. This work will be carried out in Aberdeen, Evanton, and Newcastle.
2. Design, manufacture, and supply of two high-pressure/high-temperature vertical, subsea monobore trees and wellheads, awarded to OneSubsea UK at its Leeds facility.
3. Design, manufacture, and supply of the subsea control system, including the hydraulic and electrical components to be installed both subsea and on the Britannia Bridge Linked Platform (BLP), to Aker Solutions at Aberdeen.
Rosebank is 80 mi (130 km) northwest of the Shetland Islands, in water depths of approximately 3,600 ft (1,100 m). The project will include anFPSO, production and water injection wells, subsea facilities, and a gas export pipeline.
Rosebank, discovered in 2004, is estimated to contain total potentially recoverable oil-equivalent resources of 240 MMbbl. The Rosebank owners are Chevron North Sea (operator) with a 40% equity interest; Statoil (U.K.), 30%; OMV (U.K.), 20%; and DONG E&P (UK), 10%.
Alder, discovered in 1975, is 100 mi (160 km) from the Scottish coastline and 37 mi (60 km) from the UK/Norway median line. The high-pressure/high-temperature gas condensate field lies in water depths of 492 ft (150 m) and it will be developed via a subsea tieback to the existing Britannia Bridge Linked Platform (BLP) in block 16/26.
