Ørsted has commissioned TÜV NORD to certify the submarine cables for the Borkum Riffgrund 3 wind farm, and the transformer station and the submarine cables for the Gode Wind 3 wind farm in the German North Sea.
With 83 turbines and a total capacity of 900 MW, Borkum Riffgrund 3 will be the largest wind farm in German waters. The wind farm will be connected to TenneT’s DolWin 5 offshore grid connection system.
Borkum Riffgrund 3 will not feature an offshore substation as the wind turbines will be connected directly to the DolWin epsilon platform via 66 kV cables.
Gode Wind 3 will feature 23 turbines with a total capacity of more than 242 MW. The wind farm will also have its own transformer station developed by Ørsted.
A total of around 150 kilometers of submarine cables will be laid, TÜV NORD said.
The final investment decision for the two projects is still pending.
Ørsted commissioned TÜV NORD to certify the transformer station and the submarine cables at the two wind farms in order to be able to prove the fulfillment of legal and safety-related aspects within the meaning of the Marine Plant Ordinance.
The TÜV NORD wind energy team will first conduct a design test. This is followed by production monitoring, during which the production facilities at the manufacturer and, if necessary, at suppliers, are examined. The wind energy experts then examine the transportation of the structural components from land to their destination at sea and their installation. The final component of the certification is the commissioning.
“We are very proud to be able to actively support the expansion of offshore wind energy – especially ‘on our doorstep’ – with this comprehensive service package and our technical expertise,” said Alexander Ohff , Head of the Renewable Energies segment at TÜV NORD.
Gode Wind 3 and Borkum Riffgrund 3 will be built without subsidies and are expected to be commissioned by 2025.
