Class calls for leaders in wind turbine safety

Classification society DNV GL is calling on major stakeholders in the wind industry to develop new guidelines to improve wind turbine structures and lessen the impacts of earthquakes and cyclones.

With the development of the alleviating cyclone and earthquake challenges for wind farms (ACE) as a joint industry project, DNV GL aims to gather experience from cross-industry players and align wind turbine design for extreme weather conditions.

Emerging offshore markets in the Asia Pacific region, such as Taiwan, Japan, and Korea as well as some areas in the United States, are greatly affected by cyclones and their impacts on their wind turbine farms. Teamed with the ambitious expansion plans these countries have, to develop multi-megawatt offshore wind projects, there is a vital need for a joint industry approach in the design process of these wind turbines. Not only in the face of extreme local environmental condition, but also to ensure the safety of these offshore structures.

The ACE project also aims to avoid duplication of work between wind farm developers, designers, turbine manufacturers and certification bodies, which increases costs of projects and causes delays in project development. By doing so, the stakeholders hope to reduce uncertainty in the design of offshore wind turbines and bring transparency to the industry.

Kim Mork, executive vice president renewables certification at DNV GL commented, “the ACE project will help to minimise cost, warranty and liability risks and optimise wind turbine design for seismic and typhoon conditions.”

The call for partners is now open, companies interested in joining the project can contact Marcus Klose, project manager of the JIP and head of section for Steel Structures at DNV GL, Renewables Certification.
