Jan De Nul Group has been contracted to transport and install a total of 41 wind turbines of 8.4 MW each for the offshore wind farm Vesterhav Nord & Syd in Denmark for Vattenfall. All together, these turbines will produce enough green electricity for the annual needs of approximately 380,000 Danish households.

Jan De Nul informed its jack-up installation vessel Vole au vent will be mobilised for this installation project.

The contract between Jan De Nul and Vattenfall includes the design, engineering, manufacturing, procurement and delivery of the Sea-Fastening. The company will also be responsible for the engineering of the RAMS for the marine operations related to the wind turbine installation, as well as the transport and installation of the 41 Siemens Gamesa wind turbines with the jack-up installation vessel Vole au vent.

“After the successful installation of 72 wind turbines for the 604 MW Kriegers Flak wind farm – the largest in Denmark – we are very pleased with the opportunity to build further on our experience together with Vattenfall,” Jan Van Impe, area manager offshore renewables Jan De Nul Group, said.

Both offshore wind farms are located in the Eastern part of the Danish North Sea. The Vesterhav Nord offshore wind farm is based west of the coast of Vejlbi, and the Vesterhav Syd offshore wind farm is located close to the Sondervig coast.

The two offshore wind farms are expected to be fully operational by the end of 2023.
