Spain’s Siemens Gamesa Renewable Energy said on January 16 that the company launched the SG 10.0-193 DD, SGRE’s first 10+ MW offshore wind turbine, with blades almost the same length as a soccer field.

“The new SG 10.0-193 DD combines experiences and knowledge from five generations of proven direct drive technology in one 10 MW turbine,” Siemens Gamesa CEO Markus Tacke said. “A showcase of strong performance, swift time-to-market, and low risk in the offshore wind energy market,” he added.

According to Siemens Gamesa, the 10 MW rating is made possible through a larger generator diameter, building on the proven SGRE Direct Drive generator technology.

By increasing the rotor diameter to 193 meters, this new wind turbine offers up to 30% more AEP than its predecessor, the SG 8.0-167 DD. Its 94-meter-long-blades provide a swept area of 29,300 square metres. Each blade is almost the same length as one soccer field, SGRE said.

The technology on the offshore direct drive platform allows for the re-use of most components from previous generations, providing a short time to market, Siemens Gamesa said, adding that the prototype is expected to be installed in 2019 with commercial market deployment expected in 2022.

The nacelles of this new offshore wind turbine will be initially manufactured at the SGRE factory in Cuxhaven, Germany, the world’s largest plant for offshore wind turbine nacelles, Siemens Gamesa said.

The annual energy production of one SG 10.0-193 DD is sufficient to supply about 10,000 European households with electricity, SGRE said, explain that this means that an offshore wind park composed of 20 of these turbines would cover the annual electricity consumption of a city the size of Liverpool.
