DNV GL certifies 8 MW offshore prototype

18 January 2017

DNV GL has assessed Siemens’ new offshore turbine in development and awarded its Wind Power division the Prototype Certificate for its 8 MW SWT-8.0-154 unit. The prototype certification confirms all relevant safety features of the turbine according to the Danish Executive Order BEK 73:2013 and IEC 61400-22, allowing installation of the prototype to demonstrate its performance. By erecting the turbine at the test centre for wind turbines in Østerild, Denmark, Siemens is able to perform the measurement campaign for the next phase of the type certification process which is crucial to bringing the turbine to the market.
“The third evolution on the offshore direct drive platform truly marks the move towards industrialising offshore wind power” commented Morten Rasmussen, head of Siemens Wind Power Technology.
The SWT-8.0-154 turbine is an evolution of the SWT-6.0-154 and the SWT-7.0-154 turbines. The main changes going from SWT-7.0-154 to the SWT-8.0-154 consist of an upgraded generator including the adjacent electrical system and an advanced control system. The upgrade to 8 MW is made possible through the introduction of new magnet technology of a higher grade than that introduced in the SWT-7.0-154, enabling a rated power increase of more than 14%.
