Aker Solutions is set to deliver the modules for the world’s first subsea gas compression system at the Statoil-operated Åsgard field.

The facility, scheduled to come on stream in 2015, will enable the recovery of an additional 282 million barrels of oil equivalents.

“The groundbreaking technology at Åsgard brings us one crucial step closer to placing a fully-functioning production and processing system on the seafloor,” said Per Harald Kongelf, head of Aker Solutions in Norway.

The Åsgard subsea gas compression facility is set to go on stream in 2015 after the two 11.5-megawatt compressors are installed.

Gas compressors maintain output as reservoir pressure at gas-producing fields drops over time.

To date they have been installed on platforms but Statoil hopes that placing them on the seabed near the wellheads will improve recovery rates and cut capital and operating costs.

The modules will be assembled into two trains that will each hold a compressor. They will be placed in an 1,800-tonne steel frame that was installed at the Norwegian Sea field in July last year. The modules for the first train will be delivered in instalments from now through January. The second train and compressors will be delivered in the first quarter of next year.

The compression system will boost gas pressures at the Midgard and Mikkel satellite deposits in the Norwegian Sea to potentially extend Åsgard's production life by as many as 20 years, Aker Solutions said.
