More than 200 miles of 66 kV inter-array cables have been installed by delivery partners working on the construction of the Dogger Bank A offshore wind farm.
The cables were laid by Deme Offshore’s Viking Neptun, with burial works completed by Deme Offshore’s Living Stone. This work marks the completion of all inter-array cables on the first phase of the wind farm, Dogger Bank A, which began generating power in October 2023.
The network of 95 cables, in lengths up to 8.6 miles, will connect 95 Haliade-X 13 MW turbines to the Dogger Bank A offshore converter station. From here, the electricity is converted into direct current for transmission to Dogger Bank A’s onshore converter station via a high-voltage direct current (HVDC) system.
The 66 kV inter-array cables were manufactured by Hellenic Cables under a contract with Deme Offshore. Hellenic Cables and Deme Offshore are also responsible for the manufacture and installation of inter-array cables for Dogger Bank B and C. The first inter-array cable for Dogger Bank B is expected to be installed from autumn 2024.The project is a joint venture between SSE Renewables (40%), Equinor (40%) and Vårgrønn (20%).
