DNV GL and the wind turbine blade manufacturer Sinoma signed a partnership agreement for certification of Sinoma’s products to improve the reliability and quality of blades manufactured in China. Certification ensures that turbines that use blades produced by Sinoma comply to international safety and reliability standards throughout their lifespan, in onshore and offshore wind applications. As wind turbines increase in size, the failure of key components as rotor blades can lead to significant losses for the different stakeholders involved. “Turbine manufacturers constantly work on improving quality and reliability of wind turbine components such as rotor blades and gearboxes for example,” explains Daniel Hein, Country Manager China for Renewables Certification, DNV GL.
