Equinor has awarded Ocean Installer a contract to replace a compressor module at the Åsgard subsea compression station at Åsgard field on the Haltenbanken in the Norwegian Sea. The objective is to replace the module with a new, upgraded module giving higher pressure ratio.
According to Ocean Installer, this is the first time any of the modules in the subsea compression station will be retrieved and installed with the use of a vessel crane.
A test lift, offshore simulation training, pre-commissioning, and ROV operations are also part of the scope. Engineering preparation has begun, and offshore operations will take place this year.
The modules at the station were previously installed by Ocean Installer’s North Sea Giant vessel, equipped with a purpose-built special handling system. The subsea compression system helps maintain the production rate from Midgard and Mikkel fields. Water depth in the area is 240-310 m.
