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. www.siemensgamesa.com 2 O19 20 June 2019 03 elcome to reNEWS Offshore Technology are also becoming more capable and the scope of Yearbook 2019, the fourth edition of contracts more advanced as the industry seeks to Wour comprehensive reference for the drive down costs ever further. hardware and assets required to deliver an As the growth of the offshore wind industry offshore wind farm. continues apace, so does OTY.
