Installation underway for DolWin Kappa platform

Cables Converters General Grid Substations Windfarms

TenneT announced that the 900 MW offshore platform DolWin Kappa has arrived on site and installation is underway in the German North Sea.
The platform consists of a foundation structure (jacket) and a superstructure (topside). The two have a combined height of about 82 metres, so the platform will rise about 53 metres above the surface of the North Sea. In addition, there will be a bridge that will connect DolWin kappa with DolWin beta (grid connection system DolWin2), which was already commissioned in 2016, in order to use the already existing infrastructure of the parent platform.

After the platform is commissioned in 2023, it will convert the alternating current generated by offshore wind farms into direct current, which will then be transmitted to Hilgenriedersiel on the mainland via an approximately 45-kilometre-long subsea cable. From the landfall in Hilgenriedersiel, the electricity will be transmitted to Emden by a land cable, which will also be 45 kilometres long. Here on land, TenneT has built the Emden/Ost converter station and transformer station to convert the direct current back into alternating current and then feed it into the high-voltage grid at the correct voltage level.
