All Turbines Installed at Denmark's Largest Offshore Wind Farm Posted 22/06/2021 20:54 Offshore installation contractor Jan De Nul has completed the installation of 72 wind turbines at Vattenfall's Kriegers Flak offshore wind farm in Denmark. The Siemens Gamesa turbines, at 8.4MW each, will produce enough green electricity for the annual needs of approximately 600,000 Danish households. Jan De Nul used the "Vole au vent" offshore installation vessel for the project to install the 72 wind turbines, each 187 meters high. The wind farm covers an offshore area of 132 km² at 15 to 40 kilometers off the Danish East coast. The Kriegers Flak offshore wind farm is the largest in Denmark and increases Denmark's wind production by no less than 16 percent, Jan De Nul said Monday.
