Jan De Nul to transport and install turbines for Denmark’s offshore wind farm


Denmark Jan De Nul Group will transport and install 41 wind turbines of 8.4 MW each for Vattenfall Denmark’s offshore wind farm Vesterhav Nord & Syd.

These turbines will generate enough green electricity to meet the annual needs of approximately 380,000 Danish households. Vole au vent, Jan De Nul’s jack-up installation vessel, will be mobilized for this installation project.

Jan De Nul and Vattenfall’s contract includes the design, engineering, manufacturing, procurement, and delivery of the sea-fastening. Jan De Nul will also be in charge of the RAMS for the marine operations associated with wind turbine installation, as well as the transport and installation of the 41 Siemens Gamesa wind turbines using the jack-up installation vessel Vole au vent.

With an anticipated annual production of 1,569 GWh, Vesterhav Syd and Nord will cover the annual electricity consumption of around 380,000 Danish households. Vesterhav Syd and Nord will increase Danish electricity generation from wind turbines by more than 10 per cent. The two wind farms will consist of 20 and 21 Siemens Gamesa 8.4 MW turbines respectively. Vesterhav Syd and Nord are situated in the North Sea, between 4.2 and 10 kilometres off the west coast of Denmark.
