The independent energy expert and assurance provider DNV has published new Technical Note providing principles for determining site extreme wind speeds for wind farms caused by tropical cyclones. The document is published after an extensive industry collaboration to increase transparency and to reduce uncertainty in the design of wind farms in emerging offshore wind markets such as Taiwan, Japan, Korea and the US. DNV’s Renewables Certification Executive Vice President Mr Kim Sandgaard-Mørk said “In DNV’s latest Energy Transition Outlook report we predict that the share of offshore wind in total wind electricity generation will rise to 40% in 2050. Especially for emerging offshore wind markets with ambitious roadmaps, tropical cyclone loads are of critical importance. Recent events like Hurricane Ida prove that wind farms need to be designed for these extreme local environmental conditions to support the plans to develop multi-megawatt offshore wind projects.”The Technical Note “Site extreme wind speeds due to tropical cyclones for wind power plants” is a result of a global collaborative effort, with more than 20 wind industry leaders, including OEMs, project developers, designers, and experts from Asia Pacific, Europe and North America. After only 18 months of work the Joint Industry Project ACE, Alleviating Cyclone and Earthquake Challenges for Wind farms, has been able to gather enough experiences from cross-industry players to align wind farm design principles for those extreme environmental conditions.
