Chantiers de l'Atlantique (CdA) reports that the official inauguration of the Arkona offshore wind farm takes place on 16 April In Germany.


CdA was responsible for the design and construction of the topside substation, 50m x 35m x 15m. The 385 MW transfers the energy produced by 60 wind turbines of over 60MW each to the German transmission system. The unit was transported by barge from the Saint-Nazaire yard in 2018.

The automated substation is designed to manage the wind farm autonomously, without human intervention, thanks to a large electronic PLC system.

CdA also provided the foundation for the substation, a 53m high jacket structure with a total weight of 1,800 tonnes. The unit was delivered ahead of schedule and commissioned n the summer of 2018.

CdA applied the processes and technologies learned through building large complex ships to design this substation, achieving weight savings of around 20% on the metal structure, which significantly reduced construction costs and facilitated the installation.

Additionally, CdA was responsible for the substation projects for the Westermost Rough Offshore Parks for Orsted (formerly Dong Energy) in 2014, and Rentel (2018), both located in the North Sea in Great Britain and Belgium respectively.

"We are proud to be associated with the success of this project, which will be a benchmark in European offshore wind energy. The dedication of our teams over these three years in satisfying leaders in the energy sector, such as Eon, Equinor and 50Hz, has been rewarded. We are also honoured by the presence of several high level politicians, which confirms the success of this FrancoGerman cooperation and their dedication to the European energy transition," said Frédéric Grizaud, Director of the Marine Energy Business Unit.
