• 36 foundations
  • 100 installation days
  • 460000 families provided with green power
  • 450 MW on the German electricity network

Following the success of the Nobelwind project, Jan De Nul continues to strengthen its tier one position in offshore wind with a successful Borkum Riffgrund 2 installation project. Deploying the Vole au vent, 36 monoiles were driven into the seabed, while fully complying with the very strict German noise standards.

Hammering in silence

The Vole au vent sailed out for the installation of 36 wind turbine foundations in Borkum Riffgrund 2 project, an offshore wind farm in the German North Sea. The wind farm will have a total output capacity of 450 MW, generating green energy for 460,000 families. The client for this project was the Danish renewables industry leader Ørsted. Jan De Nul was responsible for the transport and installation of the foundations.
The engineering works started in 2017, in our offices in Aalst. Here, we made all preparations in terms of HSE plans, equipment design, method statements, and subcontractor appointment. The next stop was Eemshaven, where the offshore installation vessel Vole au vent was converted using project-specific equipment. Senior Project Engineer Offshore Paolo De Temmerman remembers it all too well: “The Vole au vent arrived with only the sea-fastening structures on board. In only six days, we brought all the extra equipment on board and installed it.”
