Deme Offshore has laid all inter-array cables, manufactured by its partner Hellenic Cables, for the first phase of 3.6 GW Dogger Bank offshore wind farm in UK.
More than 200 miles of 66KV inter-array cables have been successfully installed by delivery partners working on the construction of the world’s largest offshore wind farm.
The cables were laid by DEME Offshore’s Viking Neptun, with burial works being 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 a multitude of lengths up to 8.6 miles, will connect Dogger Bank A’s 95 Haliade-X 13MW turbines to the Dogger Bank A offshore convertor station.
From here the electricity is converted into direct current for transmission to Dogger Bank A’s onshore convertor station via a pioneering HVDC system.
The laying of cables has been carried out using a specialist cable lay vessel that uses a carousel and tensioner device, to deploy cable over the stern chute of the vessel and onto the surface of the seabed.
The second stage involves connecting the cable to the offshore platform as well as each individual wind turbine.
