SKF-Supplied Magnetic Bearings for Asgard Subsea Compression

SKF has supplied magnetic bearings for use in the world’s first subsea gas compression system at the Asgard gas field off the Norwegian coast.

SKF has been involved in the development of the project for five years, working in conjunction with MAN Diesel & Turbo, the manufacturer of the electric motor-driven centrifugal compressors that are a part of the overall gas compression system.

Ole Kristian Joedahl, Sales and Marketing Director, Industrial Market, says, “Our magnetic bearings played a key role in developing this autonomous subsea gas compression system, a significant step for the oil and gas industry. They simplify the system architecture by removing the need for lubricating oil, seals and gearbox. Furthermore, the magnetic bearings are frictionless, enabling higher rotation speeds, leading to smaller compressor modules and, ultimately, lighter processing plant infrastructure and reduced environmental impact.”

In addition to the magnetic bearings, SKF is also providing a remote bearing control and monitoring system which facilitates accurate maintenance planning.
