Jan De Nul Group and Smulders join forces to build two gigantic gravity-based foundations for the high voltage station of the Danish offshore wind farm Kriegers Flak. The foundations have a weight of 10,000 tonnes and 8,000 tonnes and are constructed on top of a barge in the port of Ostend.

The foundations consist of a concrete part (the so-called Gravity Based Foundations, or GBF) and of a steel structure on top of it. Jan De Nul Group is responsible for the design and construction of the concrete GBF, while Smulders is in charge of the design and construction of the steel shafts and decks to be placed on top. The steel structures were constructed on the site of Smulders in Hoboken and were shipped to the port of Ostend last weekend.

This week the steel structure will be placed on top of the concrete structure, a milestone for the project.

By the end of December, the foundations will be finished and ready to be transported to Denmark. Jan De Nul Group will be in charge of the installation of the foundations, the ballasting and the placement of scour protection.
