Aker Solutions is to supply a subsea production system for Statoil’s deepwater Aasta Hansteen field development offshore Norway after signing a NOK 2 Bn (US $367m) contract with the state-owned operator.
Aker Solutions only recently signed a NOK 280m ($51m) contract with the operator for the supply of deepwater umbilicals for the field (see below).
The workscope for the subsea production system includes three template-manifold structures, seven subsea trees, in addition to wellheads, controls, workover and tie-in systems. The contract also contains options related to Aasta Hansteen which Statoil may also exercise.
“Aker Solutions is dedicated to supporting Statoil in optimising their assets and maximising production rates and gas recovery at Aasta Hansteen. We are very honoured to be involved in this major deepwater project,” said Alan Brunnen, head of Aker’s subsea business.
Management, engineering and procurement will primarily be performed at the contractor’s headquarters in Fornebu, Norway. Fabrication of the subsea trees and workover systems will be completed at the Tranby manufacturing centre, outside Oslo. The production of the template-manifolds will be carried out at Aker Solutions’ facilities in Egersund on the west coast and Sandnessjøen in the northern part of Norway. The company’s Aberdeen facility in the UK will deliver the control systems and the wellheads.
Aker is already investing heavily in the northern part of Norway and in October last year acquired a fabrication facility in Sandnessjøen. That facility will provide several fabrication services for the company and will be deeply involved in the Aasta Hansteen project, says Aker. The fabrication of the template-manifolds in Sandnessjøen will also create regional spin-off effects, it added.
Aasta Hansteen is the deepest subsea development in Norwegian waters to date and will provide a new deepwater standard for such production systems including new technology developments. The first deliveries for the subsea production system will be made in the first half of 2015.
