“…Chen et al conducted failure investigations of rotor blade damage, tubular tower collapse, and wind turbine (WT) under super typhoons on the southeast coast of Mainland China, and they found that the change of wind direction is critical during typhoons. Lian et al investigated the wind load characteristics of OWTs under typhoon conditions with full 360‐degree wind directions considering the variations in the wind direction and different wind rotor parking positions using a 3‐D numerical simulation. Kim and Manuel carried out a framework for estimation of structural damage to offshore wind plants during hurricanes.…”

Tropical cyclones are a high risk to offshore wind turbine (OWT) support structures, so the design conditions, including this risk, are necessary for tropical cyclone frequent occurrence zones. This study developed a computer program to carry out a critical ultimate load analysis and determine the optimum design for a Jacket‐type OWT support structure. The total weight of the OWT support structure after the optimal steel design with the yaw operative condition is always considerably smaller than that without for the steel design results under the loads of the GL Tropical Cyclone Technical Note (GL TCTN). This paper studies OWTs under the tropical cyclone classes 1 to 3 and the terrain categories A, to C, where the 1‐minute wind speed at 10‐m height is gradually increased from classes 1 to 3, and the surface roughness decreases from A to C. When the yaw can operate, the total steel weight consumption due to the tropical cyclone 1C, 1B, and 2C loads is lower than that for the IEC 61400‐3 loads. In the case of 1A, the overall steel consumption is only slightly higher than that of the IEC 61400‐3. However, for other conditions, the design should include the GL TCTN loads. For the yaw inoperative condition, the GL TCTN results are always largely dominant in the steel design, so the use of only the IEC 61400‐3 condition will result in extremely high risk to OWT support structures.

“…They suggested conducting an analysis of an idling wind turbine under gust conditions in the typhoon-prone regions. Lian et al [34] numerically simulated the aerodynamic loads on blades with different wind directions based on the CFD method, with consideration of the shutdown of the yaw system during a typhoon. Chen et al [12] calculated the local mean wind profiles at each turbine site using three-dimensional CFD calculation considering the terrain topography of a wind farm reconstructed from global positioning system (GPS) data.…”

A typhoon is a tropical cyclone in the western Pacific Ocean and the China seas. Typhoons are some of the most destructive natural disasters on Earth. In China, typhoons have had major impacts on the stability and structural integrity of offshore wind turbines in the complex and harsh marine environment. In this research, first, the main causes of wind turbine damage were analyzed based on the characteristics of a typhoon and a wind turbine structure for typical typhoon-induced accidents. Second, the research progress of the anti-typhoon design of offshore wind turbines and the anti-typhoon strategy of wind farms operation and maintenance was summarized. Finally, the problems to be further solved in these research fields were presented to provide references for the development of offshore wind turbines, in particular, floating wind turbines in typhoon-prone areas.

“…The windy South China Sea has also been studied from the other coast line across the Strait, in China. Chinese scholars have analyzed the special weather conditions with focus on the damage inflicted to offshore wind turbines by typhoons which has been coupled with thoughts on potential implications on WTG design efforts [67]. In addition, implications for wind and waves respectively as seen from a floating offshore wind turbine perspective have been analyzed [68,69].…”

This research presents an industry level gap analysis for Chinese offshore wind, which serves as a way to illuminate how China may fast track industry evolution. The research findings provide insight into how the Chinese government strongly and systematically decrees state-owned Chinese firms to expand into overseas markets to speed up learning efforts. Insights are offered regarding the nation-level strategic plans and institutional support policies mobilized by China in order to be able to conquer market shares internationally by building a strong home market and then facilitating an end-to-end and fully financed export solution. This is interesting in itself and in particular so because it now also includes complex billion-dollar megaprojects such as turnkey offshore wind farm assets with an expected lifespan of 30+ years. Research findings are provided on how European and Chinese firms may successfully forge long-term alliances also for future Chinese wind energy export projects. Examples of past efforts of collaboration not yielding desired results have been included as well. At policy level, recommendations are provided on how the evolution of the Chinese offshore wind power industry can be fast-tracked to mirror the revolutionary pace, volume, and velocity which the Chinese onshore wind power industry has mustered.
