Two huge concrete gravity based wind farm foundations have set sail from Ostend, Belgium, for the Kriegers Flak offshore wind farm in the Baltic Sea, says Jan De Nul Group.
It's only the third wind farm to use gravity based foundations in Europe. Read about the first two here.

The tug Zeus of Finland is towing the barge carrying the 10,000-tonne and 8000-tonne foundations (pictured right) to the Baltic Sea. The foundations, which will support the wind farm’s high voltage station, are set to arrive onsite around 15 January. Installation is set for the end of January and mid-February. Once both are installed, Jan De Nul Group’s multi-purpose vessel Adhémar de Saint-Venant will start with the ballasting and scour protection works.
Netherlands-based Jan De Nul and Belgium-based Smulders constructed the foundations. Both foundations consist of a concrete part and a steel structure on top. Jan De Nul Group was responsible for the design and construction of the concrete GBF, while Smulders took care of the design and construction of the steel shafts and decks placed on top.
Kriegers Flak, which will be Denmark's largest offshore wind farm, will consist out of two parts. Kriegers Flak A, the west section, will have a total capacity of 200MW. The east section, Kriegers Flak B, will have a total capacity of 400MW. Each section will dispose of its own substation, serving both for the future Krieger Flaks offshore wind farm as well as an interconnector between the Danish and German power net.
By 2022, the wind farm will start generating CO2-free electricity for approximately 600,000 households. The interconnector project is funded by the European Energy Programme for Recovery.
