Norwegian oil company Det norske oljeselskap ASA (Det norske) has received consent for manned underwater operations in 2015 on the Alvheim and Bøyla fields, offshore Norway. The fields are located in blocks 24/6 and 24/9 in the central North Sea, close to the boundary with the UK Continental Shelf.
The Alvheim field has been developed using a floating production, storage and offloading (FPSO) unit. The field includes three discoveries: Boa, East Kameleon and Kneler. These have been developed using individual subsea facilities tied back to the Alvheim FPSO.
The Bøyla field is around 28 kilometres south of Alvheim. The field has been developed using a subsea facility tied back to the Alvheim FPSO.
Water depth at both sites is around 120 metres.
Det norske has signed a contract with Technip Norge AS for the supply of underwater services for the Bøyla field and the Alvheim FPSO and connected subsea facilities. Technip will be using DSV Skandi Arctic and DSV Wellservicer, and the light diving craft LDC Technip Seahunter.
The Petroleum Safety Authority (PSA) Norway has given Det norske consent for these activities until the end of 2015. Det norske must notify the PSA before the individual activities start.
