Dogger Bank Wind Farms has named OHT as its preferred supplier for foundation installations at the consortium’s offshore wind farms.
Dogger Bank, a joint venture between SSE Renewables and Equinor, is a 3.6 GW offshore wind development consisting of three offshore wind farm projects – Creyke Beck A and B, and Teesside A – located about 80 miles off the east coast of Yorkshire, England, in the North Sea.
OHT’s Alfa Lift, set to be the world’s largest and most efficient custom-built offshore wind foundation vessel, will be responsible for the transport and installation of monopile foundations and transition pieces for Creyke Beck A (1.2 GW) and Creyke Beck B (1.2 GW). GE’s Haliade-X 12 MW wind turbine will be installed throughout the wind farms.
Using a single vessel, the foundations will be transported to the offshore site and installed in water depths of up to 115 feet. The Alfa Lift heavy installation crane vessel will carry 10 monopiles and transition pieces on deck per voyage.
“Dogger Bank Wind Farms is paving the way for future offshore wind developments – not just in the U.K., but globally – by utilizing some of the most innovative and efficient technology on the market, like the Alfa Lift vessel,” says Paul Cooley, SSE Renewables’ director of capital projects. “We are very pleased to have OHT working with us as we deliver this ground-breaking project.”
“The monopiles that will be installed at Dogger Bank will be amongst the largest ever used on an offshore wind farm, and we needed a vessel that would allow us to deliver our project in the safest and most efficient way,” comments Steve Wilson, project director of Dogger Bank Wind Farms. “OHT’s Alfa Lift’s capability offers us this solution, and we look forward to working with them to deliver Dogger Bank Wind Farms.”
Transport and installation of the monopiles and transition pieces for Creyke Beck A and Creyke Beck B are expected to be performed between 2022 and 2024.
