Subsea gas compression contract

Åsgard is located at Haltenbanken outside Norway in water depths varying from 240-310 metres. The Midgard and Mikkel reservoirs contain gas and condensate that are transported through long distance flowlines to the Åsgard B platform. Contract party is Aker Solutions' subsidiary Aker Subsea AS.

When gas is produced the pressure in the reservoir decreases and the well flow may need boosting in the form of compression. In many instances, subsea compression technology is necessary to create enough pressure for the hydrocarbons to travel up the pipelines to the receiving terminal. The subsea compression system provides improved energy efficiency and safety, and lower investment and operating costs when compared to using a traditional platform and is a concept suitable for most large subsea gas fields.

Aker Solutions' scope of work for the subsea compression system includes a subsea compressor manifold station (SCMS), subsea compressor station (SCSt) template structure, three identical compressor trains, all electrical control systems, high voltage electrical power distribution system, topside equipment, and tooling, transport and installation equipment.

The project will be managed out of Aker Solutions' headquarter in Oslo; Norway, while the equipment will be primarily manufactured at Aker Solutions' facilities in Egersund, and Tranby, Norway, and in Aberdeen, UK. Final equipment deliveries will be made in stages with the SCMS and the SCSt template structure delivered in 2013 and the compressor trains, controls and power equipment delivered in 2014.
