Seafarer, belonging to vessel-based subsea well construction and intervention services provider AKOFS, has just completed mobilisation for an upcoming three-well campaign as part of the five-year contract for well intervention for Equinor on Nowegian Continental Shelf (NCS).

The work has been performed at the Myklebust Yard in Norway. The OneTeam model implemented by AKOFS, was responsible for completing an intensive mobilisation without any serious safety incidents.

Following successful riser-less interventions since second half of 2020, Equinor and AKOFS have mobilised for a riser-based campaign using coiled tubing through an option in the contract. The AKOFS Seafarer has proven to be an extremely efficient vessel for riser-less interventions year round on NCS, thanks to its unique set-up, size and lay-out as well as the OneTeam model implemented by AKOFS and its operating partners Archer, WellTec and IKM Subsea. Utilising its flexibility, a high pressure work-over riser system has now been mobilised and added to the vessel together with a coiled tubing spread and fluid return treatment system.

The AKOFS Seafarer is now en-route to Equinor-operated fields Norne, ├ůsgard and Statfjord where well objectives will include scale, sand and debris removals, perforations as well as installation of plugs and screens.
