One of the world’s largest offshore substations has commenced a three week voyage from Cadiz in southern Spain to the German zone of the Baltic Sea, where it will eventually be sited at the 350 MW Wikinger offshore wind farm.

Business Green reports that the substation has a steel structure, which weighs 4,550 tonnes alone and is dubbed ‘Andalucía’.

Built by Spanish state-owned shipbuilding company Navantia at the Puerto Real shipyard in Cadiz, it is the first offshore substation to include two separate topsides – areas above the water line where control rooms and landing decks are housed.

The two areas are needed since the station will also be used by German electricity system operator 50Hertz to support its own offshore wind developments.

The €1.4bn (£1bn) Wikinger wind farm will consist of 70 wind turbines spanning an area of around 34 square kilometres and is expected to provide enough power for 350,000 households when it comes online at the end of 2017.
