Monopiles
Borkum Riffgrund 03
Borkum Riffgrund 3 is an Ørsted offshore wind farm in the German North Sea, approximately 53 kilometers off the coast of Borkum. With a capacity of 913 MW and 83 Siemens Gamesa SG 11.0-200 DD turbines, it will be Germany’s largest offshore wind farm. The generated electricity will be sold directly to companies without subsidies through long-term purchase agreements. Commissioning is planned for 2025.
SK Korrosion has prepared six monopiles in Stralsund for this wind farm in 2024.
Dogger Bank "A"
The Dogger Bank “A” is a large, elongated sandbank in the North Sea in the United Kingdom, in some places only about 13 meters below sea level. It is considered the northwestern limit of the Great German Bight. The Dogger Bank “A,” located within the British Economic Zone, is designated a nature reserve. The manufactured monopiles will be installed on the 1.2 GW Dogger Bank “A,” the first phase of the three-phase project. A total of 285 units will be manufactured.
Dogger Bank "B"
Dogger Bank “B” is the second phase of the world’s largest offshore wind farm in the North Sea. With a capacity of 1.2 GW and 95 GE Haliade-X 13 MW turbines, Dogger Bank B will generate enough energy to power millions of British homes. The monopiles will be manufactured by Sif Netherlands and Smulders Projects and installed approximately 130 kilometers offshore. The generated electricity will be transmitted to shore using innovative high-voltage direct current (HVDC) technology, which minimizes losses. Completion is scheduled for 2024 and marks a significant step forward for renewable energy.
Dogger Bank "C"
Dogger Bank “C” is the third phase of the Dogger Bank Wind Farm, the world’s largest offshore wind farm in the North Sea. It comprises 87 GE Haliade-X 14 MW turbines and will generate 1.2 GW of energy, enough to power approximately 1.5 million homes. As with previous phases, electricity will be transmitted to shore using innovative high-voltage direct current (HVDC) technology. Turbine installation will begin in 2025, with full commissioning planned for 2026. Together with Phases A and B, Dogger Bank C will secure electricity for a total of 6 million UK homes and further strengthen the UK’s role as a leader in offshore wind power.
