Two Kriegers Flak OSS Foundations Ready for December Ride (Photos)

Jan De Nul and Iemants have completed the two gravity-based foundations for Kriegers Flak substations. The steel structures, designed and built by Iemants (Smulders), have been placed on top of their corresponding concrete structures and the foundations are now being prepared to be transported from the port of Ostend in Belgium to Denmark by the end of December. 

The 600MW Kriegers Flak offshore wind farm in Danish Baltic Sea waters consists of two sections, each with its own substation: Kriegers Flak A with a total capacity of 200MW, and Kriegers Flak B with a total capacity of 400MW. The two substations will also serve as an interconnector between the Danish and German grids.

Under a contract signed with Energinet.dk and 50Hertz Transmission GmbH in November 2016, Jan De Nul is in charge of the design, construction, transport and installation of the GBFs, while Iemants has provided the detailed design, fabrication and transportation of the steel shafts and decks which are placed on top of the GBFs.

Jan De Nul will prepare the offshore locations and install the substation foundations with its backhoe dredger Gian Lorenzo Bernini and multipurpose vessel Adhémar de Saint-Venant.
