Subsea compression station at 900 metres
Hydro has awarded Aker Kvaerner a total contract which could be worth up to NOK850million for the Subsea Compression Pilot for Ormen Lange. This is a world first for subsea compression. If the project provides the expected results, the Ormen Lange partners will have a cost effective alternative to the offshore platform originally planned.
Full execution of the contract is subject to the Ormen Lange partners’ approval of both work programme and budget for the subsea compression pilot programme.
The aim of the project is to evaluate whether a subsea compression station, at approximately 900 metres water depth, is a viable alternative to an offshore platform. Later in the production phase, the challenge at Ormen Lange will be to boost the well stream in order to maintain production of gas and condensate from the reservoir.
The pilot is identical to one of four trains on the proposed full-scale subsea compression station. The contract includes an option for the partners to choose Aker Kvaerner to deliver the complete subsea compression station – a decision expected late in 2011. o
