50Hertz submarine cable successfully pulled into Arcadis Ost substation platform

The offshore platform Arcadis Ost is now connected to the German extra-high voltage grid.

The 220 kV submarine cable system required for this was pulled into place on the platform over the past few days. Final assembly work will now follow. Afterwards, extensive tests of the systems are imminent.

The approximately 100-metre-long submarine cable end was recovered from the seabed and pulled onto the platform in a technically demanding procedure. The submarine cable had already been positioned and wet-stored on the Baltic Sea seabed in front of the platform, in 42 metres of water depth, in September 2021. 

Simon Deplace, Technical Project Director for Ostwind 2 at 50Hertz, says:

"We are very proud that this operation was carried out quickly and safely and that we remain on time and on budget for the wider project." 

The electricity generated by the wind farm north of the island of Rügen will in future be fed into the grid at the Lubmin substation.

Ostwind 2 is the project to connect the Baltic Sea wind farms Arcadis Ost 1 and Baltic Eagle to the German high voltage grid. To transfer the power from the two wind farms, 50Hertz is building three submarine cable systems that will transmit a total of 750 megawatts (MW). Arcadis Ost 1, the wind farm of the Belgian company Parkwind, is located in the West Arkona Sea cluster. 

Baltic Eagle, the project of the Spanish energy company Iberdrola, is located in the Arkona Sea cluster. It is about 20 kilometres (Arcadis Ost 1) or 30 kilometres (Baltic Eagle) to the nearest coast of Rügen, and about 90 kilometres to Lubmin to the transformer station on the Greifswalder Bodden.
