Jan De Nul’s jack-up vessel Vole au vent has left a shipyard in Poland where the vessel underwent certain modifications to the layout of the deck and is now ready for the Borkum Riffgrund 2 offshore wind farm project.
The vessel’s aft deck was re-arranged and the funnel houses were removed to create more free space and make more efficient use of the crane’s 1,500-tonne capacity, Jan De Nul said.
The jack-up was also equipped with sea fastenings for the transport and installation of the 36 monopiles and transition pieces on Ørsted’s 450MW Borkum Riffgrund 2 wind farm in the German North Sea.
The wind farm is located 38 kilometres off the German island of Borkum and is scheduled to be fully commissioned in 2019. It will comprise 56 MHI Vestas 8MW wind turbines installed on 36 monopile foundations and 20 suction bucket jacket foundations.
