DNV GL Inviting Wind Industry To Collaborate On Cyclone&Earthquake Guidelines For Turbines

DNV GL, the world’s largest independent energy advisory and certification body, is calling on wind industry stakeholders to join a new Joint Industry Project (JIP) to mutually develop a new guideline to alleviate wind turbine structures from the impacts of cyclones and earthquakes.

DNV GL says the guidelines should be aimed at emerging offshore wind markets in Asia and U.S., so as to mitigate risks in delivery of future offshore projects.

The ACE (Alleviating Cyclone and Earthquake Challenges for Wind farms) Joint Industry Project is aiming to gather experiences from cross-industry players to align wind turbine design methodologies for those extreme weather conditions.

Seismic and cyclone impacts on wind turbines is of critical importance in emerging offshore markets such as the Asian Pacific region like Taiwan, Japan, Korea as well as parts of the United States. As these countries are entering the offshore wind market with ambitious roadmaps to develop multi-megawatt offshore wind projects, providing a joint industry approach for designing turbines for these extreme local environmental conditions is vital, to ensure the safety of the offshore structures in those emerging markets.

The lack of an aligned guideline often leads to increased work volume between wind farm developer, turbine manufacturer, designer and certification body, causing delays and increasing costs of projects. The ACE Joint Industry Project aims to bring more transparency and reduce uncertainty in the design of offshore wind turbines. The Recommended Practice will increase the financial robustness of future wind farms developed for the emerging offshore markets.

“All industry stakeholders acting in emerging markets in the Asia Pacific region and the U.S. will benefit from the ACE project as it will help to minimize cost, warranty and liability risks and optimize wind turbine design for seismic and typhoon conditions. As the focus area for this joint industry project was developed mutually with different wind industry stakeholders, the feedback during the initiating phase has already emphasized the necessity of aligning the industry in this area” said Kim Mørk, Executive Vice President Renewables Certification at DNV GL.
