FREDERICIA, Denmark — Seaway7’s jackup vessel Seaway Ventus installed the first turbine at the Borkum Riffgrund 3 wind farm, 72 km from the coast of Lower Saxony, Germany.
Cadeler’s Wind Osprey will also join the installation program, which covers 83 Siemens Gamesa wind turbines, each with a capacity of 11 MW.
Borkum Riffgrund 3 is Ørsted’s first project in German waters without an offshore substation. The new connection concept provides for a direct connection of the wind turbines via 66-kV connection cables to the DolWin epsilon offshore converter platform, operated by the German transmission system operator, TenneT.
Once complete, the Ørsted/Nuveen Infrastructure Borkum Riffgrund 3 development will have an overall capacity of 913 MW, the largest for any wind farm offshore Germany to date.
It follows close on first power from the 253-MW offshore Gode Wind 3 project, which the same partnership is constructing. This and Borkum Riffgrund 3 will almost double Ørsted’s total installed capacity in Germany.
Operation and maintenance will be handled from Norden-Norddeich and Emden in East Frisia, Germany, and Eemshaven, the Netherlands.
Currently Ørsted has about 7.6 GW of offshore wind capacity under construction across three continents, including the 2.8-GW Hornsea 3 in the UK southern North Sea.
In May the first foundation was set down at the company’s 704-MW Revolution Wind development off the US East Coast.
Seaway7 is also installing monopile foundations and transition pieces for the Dogger Bank B development in the UK southern North Sea, using the vessels Seaway Strashnov and Seaway Alfa Lift. Previously the company completed installation of the foundations for the first phase of the project, Dogger Bank A.
