Recently, Oslo-listed offshore giant Subsea7 announced on its official website that it has signed an offshore contract with Ithaca Energy, for the provision of off-station decommissioning services for the Alba Floating Storage Unit and Greater Stella field FPF-1 production facility, approximately 230 kilometres east of Aberdeen. According to the company’s standard practice, the contract value ranges from $50 million to $150 million.
This decommissioning scope includes the flushing of the subsea pipelines, provision of diver support vessel services, and seabed clearance.
Project management and engineering will commence immediately at Subsea7’s office in Aberdeen. Offshore activities are scheduled to commence in Q2 2026.
The Alba oil field is operated by Ithaca Energy, which holds a 36.67% interest. Non-operating interests are held by Waldorf Production (25.68%), NEO Energy (17%), Spirit Energy (12.65%), and EnQuest (8%).
It is understood that the Alba and D’Stella oilfield assets have entered the late stage of their lifecycle. With project operators progressively decommissioning aging subsea infrastructure and mid-life production facilities, the number of decommissioning projects on the UK continental shelf continues to rise.
Hani El Kurd, Senior Vice President of UK and Global Inspection, Repair and Maintenance, Subsea7, said: “This award provides an excellent opportunity to further demonstrate the extent of our three decades of full-field proven decommissioning expertise and our capability in delivering complex, safe and effective solutions.
“Subsea7 is proud of its longstanding relationship with Ithaca Energy, which began in 2008, and looks forward to collaborating closely throughout this project to combine our expertise and ensure its successful delivery.”
