Aker Solutions and MAN Diesel & Turbo are aiming to reduce the size and weight of subsea compression systems by at least 50%, just after one year the system went operational at the Statoil’s Åsgard field.
In the first year, the Åsgard system operated without any malfunction or interruption. It helped to recover additional 306m barrels of oil equivalents safely with a smaller environmental footprint than traditional methods. It was also found to be more cost-effective than other platforms.

Aker Solutions delivered this system in October 2015 in close collaboration with MAN and operator Statoil.
Aker Solutions chief technology officer Hervé Valla said: “We're proud to have played a leading part in developing this groundbreaking technology, which is proving its value as we now mark one year of strong operations since going on stream.
“Together with MAN, we're taking this technology further to deliver slimmer and lower-cost compression systems without compromising on effectiveness.”
Aker Solutions and MAN Diesel & Turbo partnership expects to reduce the size and weight of future systems by at least half, lowering investment and installation costs.

By GlobalDataMAN Diesel & Turbo oil and gas upstream head at Zurich Basil Zweifel said: “The next-generation of subsea compression systems will be based on proven technology and contribute to major improvements in both the recovery rate and lifetime for a number of gasfields.
“Aker Solutions and MAN will provide reliable compression systems for use at small subsea fields, as well as large deposits such as Åsgard.”
The two 11.5MW HOFIM motor-compressor-units at Åsgard were installed and put into operation on the seabed. Generally, they are installed above sea level to maintain output as reservoir pressure at gas-producing fields fluctuates with time.
