Volker Stevin International (VolkerWessels) and its partner Royal Boskalis Westminster N.V. (Boskalis) have been awarded a contract by Iberdrola Renewables Offshore Deutschland GmbH for the partial construction of the Wikinger Offshore Wind Farm in the German section of the Baltic Sea. The work comprises the transport and installation of seventy offshore wind turbine foundations and six offshore substation piles. Volker Stevin International’s share of the total contract value is approximately EUR 60 million.
The Wikinger Offshore Wind Farm is located 34 kilometers northeast of the island of Rügen and will generate a total capacity of 350 MW. Each of the seventy wind turbine foundations consists of a four-legged jacket and four piles that will be transported from four different locations in Europe to marshalling port Sassnitz-Mukran in Germany.
Volker Stevin International is responsible for the port logistics in Sassnitz-Mukran. Following the transport from the port to the wind farm the piles will be driven into the seabed making use of the innovative pre-piling concept developed by Volker Stevin International. After pre-piling the jackets will be installed and connected to the piles. The pile installation activities will be executed by a Boskalis Giant barge supplemented with Volker Stevin International and Boskalis shared equipment among which a 1,000-tonne crane. The installation of the jackets will be done by the Boskalis 2,200-tonne Taklift 4 sheerleg.
The project is scheduled to commence in the first quarter of 2016 with completion expected in the fall of 2016.
