The transformer platform for the offshore wind farm Wikinger is now complete and will be transported from Cadiz, Spain, to the Baltic Sea. Its special feature: The platform consists of two parts (topsides), which are jointly used by the wind farm operator Iberdrola and the transmission system operator 50Hertz.

The substation, which is named Andalucía, was manufactured by the state-owned shipyard Navantia in Cadiz, Spain, and handed over on schedule. Approximately 700 workers worked 90,000 hours on it during the construction phase. The platform was shipped in two parts by barge to the construction site in the German Baltic Sea between Rügen and Bornholm in August. Piles for a six-legged jacket foundation were rammed for the first time. The platform, jacket foundations and six piles weigh a total of approximately 8,500 tonnes. Together, the two topsides are almost 60 metres long, approximately 21 m wide and 16 m high. When it is complete, the main deck will be more than 21 m above sea level.

The EU Commissioner for Climate Protection and Energy Miguel Arias Cañete, Iberdrola Chairman Ignacio Galán, and representatives of the German transmission system operator 50Hertz all took part in the ceremony to celebrate completion.
