Boskalis, VolkerWessels to Handle Wikinger’s Foundations

Royal Boskalis Westminster N.V. (Boskalis) and Volker Stevin International (VolkerWessels) have been awarded a contract by Iberdrola Renewables Offshore Deutschland GmbH for the transport and installation of seventy wind turbine foundations and six offshore substation piles for the Wikinger Offshore Wind Farm in the German part of the Baltic Sea.

The contract carries a value of approximately EUR 75 million for Boskalis and EUR 60 million for VolkerWessels.

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 Sassnitz-Mukran in Germany by Boskalis barges and anchor handling tugs and Dockwise semi-submersible transport vessels.

Following the transport from Sassnitz-Mukran to the wind farm the piles will be driven into the seabed after which the jackets will be installed and connected to the piles. The pile installation activities will be executed by a Boskalis Giant barge with a 1,000-tonne crane and the installation of the jackets by the Boskalis 2,200-tonne Taklift 4 sheerlegs. The project is scheduled to commence in the first quarter of 2016 with completion expected in the fall of 2016.
