Turbines for world’s largest offshore wind farm

Dogger Bank Wind Farms, the developer of what will become the world’s largest offshore wind farm when built, has unveiled GE Renewable Energy as its preferred turbine supplier. GE will supply Dogger Bank with its Haliade-X turbine, with a generating capacity of 12 MW or more – the final number of turbines has yet to be confirmed.

Dogger Bank Wind Farms is a 50:50 joint venture between Equinor and SSE Renewables to build three 1.2 GW projects located in the North Sea approximately 130 km from the Yorkshire Coast. The projects were recently successful in the latest Contracts for Difference (CfDs) allocation round.

SSE Renewables will lead the development and construction phases of Dogger Bank and Equinor will lead on operations once completed.

The combined Dogger Bank project will have a combined capacity of up to 3.6 GW, making it the largest wind farm in the world. It will be able, says SSE, to provide enough energy to power over 4.5mn homes, equivalent to around 5% of the UK’s electricity generation.

The Dogger Bank projects will now progress towards a financial investment decision by the end of 2020. Onshore construction is expected to commence in early 2020, and first energy generation is expected in 2023.

Meanwhile, Fred. Olsen Windcarrier’s jack-up installation vessel Bold Tern fitted the last turbine at Hornsea One offshore wind farm on 25 September. Installation of the Siemens Gamesa turbines began in February – they were installed in tandem by two vessels: Bold Tern and DEME’s Sea Challenger.

Hornsea Project One consists of 174 turbines and the site is approximately 120 km off the Yorkshire coast. When fully commissioned, the 1.2 GW wind farm will become the world’s largest – for now.
