Since 2017, the Dana-operated Western Isles has been producing from two oil fields called Harris and Barra in the Northern North Sea. They are located 160km east of Shetland and 12km west of Tern field.
The project involved a subsea development of production and water injection wells tied back to a floating production, storage and offloading vessel (FPSO) with oil export using shuttle tankers.
Western Isles is scheduled to cessate production (COP) in April 2024 after which the vessel will be warm stacked.
