TÜV Nord certifies the newest turbine from Siemens Gamesa, which has a capacity of up to 15MW and a rotor diameter of 222 meters. The company will certify the turbine in accordance with the internationally recognised IECRE scheme OD 501.
TÜV Nord is responsible for the certification of the SG 14-222 DD’s prototype, scheduled for completion in 2021, and for the type certification prior to the series production. The focus is on the overall concept of the wind turbine and experts assess the system design for the planned life time of 25 years.
In addition, the quality along the supply chain and a detailed test program will be evaluated. The SG 14-222 DD is going to be tested for the so-called "Typhoon class", which is required specifically for the Japanese and Taiwanese market. The rated output of the Direct Drive wind turbine is 14MW and can be increased to 15MW by using the Power Boost function. The rotor blades measure 108 meters each, the rotor diameter is 222 meters.
