Component Design Evaluation for Hybrid Tower in Germany

  • In order to ensure the safety and quality of components to be used for a hybrid tower wind turbine in Germany, ENERCON needed an accredited Certification Body to perform the required evaluations. That’s why they turned to TÜV Rheinland.

    Basic facts

    ClientENERCON GmbH, Germany
    TimeframeJuly - August 2012
    Project locationGermany
    Main servicesComponent design evaluation
    Involved regulations/ standards

    International standard IEC 61400-22:2010

    Initial situation and requirements

    ENERCON is one of the leading manufacturers of wind turbines with more than 20,000 wind turbines installed in over 30 countries.

    With growing demand requiring onshore wind turbines to be more productive, higher towers are necessary because the higher the hub, the higher the wind speed. But because bigger towers incorporate greater risks for instability, are much more expensive and more difficult to transport, another solution had to be found. Hence the development of hybrid towers with concrete bottoms and tops of steel, a combination to ensure a safe and reliable construction.

    In order to build hybrid towers in Germany, ENERCON required extensive component design evaluation to confirm that components were designed in conformity with design specifications and the international IEC 61400-22 standard.
