Wind Energy – Vesterhav Denmark
For the offshore wind farm Vesterhav Nord & Syd in Denmark, Jan De Nul Group transported and installed a total of 41 wind turbines of 8.4 MW each on behalf of Vattenfall Denmark.
All together, these turbines will produce enough green electricity for the annual needs of approximately 350,000 Danish households.
For this installation project, Jan De Nul’s jack-up installation vessel Vole au vent was mobilised.
The contract between Jan De Nul and Vattenfall also included the design, engineering, manufacturing, procurement and delivery of the sea-fastening of turbine components.
The blade rack was delivered by Siemens. In addition, Jan De Nul took care of the studies related to transport engineering and jacking analyses of the Vole au vent.
The jack-up vessel Vole au vent left Esbjerg Harbor for the first time on 7 July 2023 to start the transport and installation of the 41 Siemens Gamesa wind turbines. Five days later, on 12 July, the first turbine was erected. On 18 October 2023, the vessel installed the last turbine, thus completing her project scope.
In February this year, DEME Offshore kicked-off the foundation installation works at the Vesterhav Nord and Vesterhav Syd offshore wind farm.
