GL Renewables Certification (GL RC) has published its new “Technical Note for the Certification of Wind Turbines for Tropical Cyclones”. The Technical Note is a supplement to GL RC’s Guidelines for the Certification of Wind Turbines and addresses the question how cyclones are influencing wind turbine designs.
An increasing number of onshore and offshore wind parks are proposed in cyclone-affected areas, mainly in the US, China, Korea and Japan. Properly designed wind parks should be able to withstand the cyclones that are likely to affect them within their lifetime. The Technical Note can optionally be applied within the certification procedure and defines the additional design requirements to be considered for type and project certification as well as requirements for site assessment. It was prepared in cooperation with academia and industry and includes knowledge from research and from already existing wind parks.
