TÜV NORD will take care of the certification of wind turbine towers for Siemens. The company has also commissioned TÜV NORD with type certification of the SWT-2.3-120 turbine of the G2 platform.
TÜV NORD will issue a significant number of the tower component certificates for Siemens. With these certificates, the towers will no longer have to be individually evaluated as major components in later turbine and type certifications; it will only be necessary to demonstrate suitability for the specific loads and to prove integration into the electric lightning strike protection / earthing concept through interface comparison and harmonisation. The type certification of the Siemens SWT-2.3-120 will also be done by the company. The turbine is designed to meet the demands of the markets in the Americas region. A prototype will also be erected in Denmark. For this reason, TÜV NORD will take both the Danish and the American standards into consideration. In the certification process as per the IEC 61400-22 Standard, the design of the complete wind turbine is tested for compliance.
