"Thialf", a powerful floating crane is helping with the completion of Germany's first offshore wind farm, alpha ventus.
Currently, the construction vessel is placing six steel foundations 30 metres deep on the seabed of the North Sea, approximately 45 kilometres north of the island of Borkum. Using these so-called ‘jacket’ foundations, the consortium of EWE, E.ON and Vattenfall will shortly erect six REpower 5M wind power turbines, each with a height of 155 metres above sea level. At completion, the alpha ventus wind farm will be comprised of at total of twelve wind power turbines. Six Areva Multibrid M5000 turbines have already been constructed and are in operation.
