Ithaca Energy let a contract to Subsea 7 SA for off-station decommissioning services at the Alba floating storage unit and the Greater Stella field FPF-1 production platform about 230 km east of Aberdeen in the North Sea.
The decommissioning scope includes flushing of subsea pipelines, provision of diver support vessel services, and seabed clearance.
Project management and engineering will start immediately. Offshore activities are scheduled to start in second-quarter 2026.
Stella field lies in the Central Graben Area of the central North Sea in about 295 ft of water. The field is a 6-well subsea tieback to the FPF-1 production platform and produces from the Stella Andrew sandstone reservoir containing light oil and rich gas condensate and the Stella Ekofisk reservoir containing a volatile oil.
Alba is a heavy oil field and was one of the first shallow Eocene reservoirs to be successfully developed in the North Sea. The field includes the fixed steel Alba Northern platform and a floating storage unit (FSU). The field was further developed in 2001 through the addition of the Alba Extreme South subsea production center.
