The installation went “according to plan” the German manufacturing giant said and the hardware will now enter the final development phase.
A prototype machine featuring a 154 metre rotor was certified by DNV GL in January. It features a 120 metre steel tower.
Siemens will carry out a series of mechanical and electrical tests on the machine with final type certification expected next year.
“The installation of the SWT-8.0-154 prototype in Østerild is an important milestone in the success story of our offshore direct drive wind turbines,” said Siemens offshore wind chief executive Michael Hannibal.
“The evolution based on our platform strategy demonstrates that innovation to lower the cost of wind energy can work without compromising the proven reliability of a technically mature product.”
