Offshore Technology Yearbook

2 O19 Generation V: power for generations

Since we released our ﬁ rst offshore direct drive turbines, we have been driven to offer our customers the best possible offshore solutions while maintaining low risk. Our SG 10.0-193 DD offshore wind turbine does this by integrating the combined knowledge of almost 30 years of industry experience. With 94 m long blades and a 10 MW capacity, it generates ~30 % more energy per year compared to its predecessor. So that together, we can provide power for generations.
