New 72 wind turbines of 8.4MW each installed at Kriegers Flak Wind will produce enough green electricity for the annual needs of approximately 600,000 Danish households.
According to Jan De Nul Group, the geographical location of the offshore wind farm offers extremely heterogeneous soil conditions with large lateral variability and boulders on the surface and below. However, the company has managed to successfully deploy a Jack-Up Installation Vessel for the installation works.
“Our project team, crew members on board the Vole au vent and all our partners involved did a fantastic job. Despite the winter weather conditions and extra challenges due to COVID-19, the works have always been on schedule, thanks to their efforts. Great teamwork! We are very proud to have helped Denmark in this giant leap in their energy transition.” – Bert Reynvoet, Project Manager of Jan De Nul Group.
The works on this project go back to 2017 and 2018 when Jan De Nul Group installed two large Gravity Based Foundations for the offshore high-voltage substations of this offshore wind farm. The company has built both concrete structures of 8,000 and 10,000 tonnes on a floating pontoon in the port of Ostend, Belgium and then towed them to Denmark. In the Baltic Sea, the crane vessel Rambiz installed both foundations on the seabed.
The Kriegers Flak wind farm in the Baltic Sea is currently the largest in Denmark. It increases wind production in Denmark by no less than 16 percent.
