Jan De Nul will transport and install a total of 41 wind turbines of 8.4 MW each for the offshore wind farm Vesterhav Nord & Syd in Denmark on behalf of Vattenfall Denmark. The offshore contractor will mobilise its jack-up installation vessel Vole au vent for this installation project.

All together, the turbines will produce enough green electricity for the annual needs of approximately 380,000 Danish households.

The contract between Jan De Nul and Vattenfall includes the design, engineering, manufacturing, procurement and delivery of the sea-fastening. Jan De Nul 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.
