“…In the absence of OWP experience, the industry inevitably faces more risks in its initial implementation than it would otherwise. The design of wind turbines in Taiwan follows European standards, leading to several incidents of wind turbine collapse and damage to blades in onshore windfarms in Taiwan as a result of typhoons [2][3][4][5]. When wind power is developed offshore, the environment and climatic conditions at sea, which are much harsher than onshore, will seriously influence construction and operation and pose a major challenge for each windfarm project.…”

Many countries have increased the use of renewable energy and strongly promoted offshore wind power (OWP). However, OWP in Asia is in the preliminary stage of development, for which no precedents exist. The literature on wind energy generation has mostly investigated the causes of onshore wind turbine accidents and risk prevention, and more work on the risks associated with domestic OWP is required for energy market development. According to statistics on international wind power accidents, most offshore accidents occur in the construction and operation stages. Therefore, this work investigates risk management in the construction and operations of offshore windfarms in Taiwan. The goal is to help decision-makers to understand better the risks of the industry and so more effectively manage them. In this study, risk factors are identified from organizing data in the literature, and research methods and action strategies are developed. Research and analysis follow the risk management steps in the PMBOK® Guide (A Guide to the Project Management Body of Knowledge). The risk rankings and preventive measures that are based on the results of this study can serve as references for relevant industry personnel in island cities and nearby Asian countries to reduce risk in the management of OWP projects.

“…According to the records of wind farms damaged by typhoons, blade breakage and tower collapse are the main failures of wind turbines [31][32][33]. Thus, it is essential to monitor the loads of the blade root and tower base under typhoon conditions.…”

A typhoon is a restrictive factor in the development of floating wind power in China. However, the influences of multistage typhoon wind and waves on offshore wind turbines have not yet been studied. Based on Typhoon Mangkhut, in this study, the characteristics of the motion response and structural loads of an offshore wind turbine are investigated during the travel process. For this purpose, a framework is established and verified for investigating the typhoon-induced effects of offshore wind turbines, including a multistage typhoon wave field and a coupled dynamic model of offshore wind turbines. On this basis, the motion response and structural loads of different stages are calculated and analyzed systematically. The results show that the maximum response does not exactly correspond to the maximum wave or wind stage. Considering only the maximum wave height or wind speed may underestimate the motion response during the traveling process of the typhoon, which has problems in guiding the anti-typhoon design of offshore wind turbines. In addition, the coupling motion between the floating foundation and turbine should be considered in the safety evaluation of the floating offshore wind turbine under typhoon conditions.

“…These studies also analyze risks and conduct statistical analyses, but they consider only a single-type, or single-cause, category. For example, [34,35] studied historical wind tower structural failures and collapses (sourced from CWIF) to explore causes, collapse mechanisms, and techniques to mitigate such risks. The work in [36] focused on accidents related to fire based on four selected cases and examined the common causes and protection methods.…”

“…Wind, along with solar power, is anticipated to constitute the majority of additional power generation by 2040 [3]. For example, in the USA, wind power has grown more than three times from 2009 (35,130 MW) to 2019 (105,591 MW) and was the largest contributor to renewable power in the USA as of 2019 [4].…”

Despite the significance and growth of wind energy as a major source of renewable energy, research on the risks of wind turbines in the form of accidents and failures has attracted limited attention. Research that applies data analytics methodologically in this context is scarce. The research presented here, upon construction of a text corpus of 721 selected wind turbine accident and failure news reports, develops and applies a custom-developed data analytics framework that integrates tabular analysis, visualization, text mining, and machine learning. Topic modeling was applied for the first time to identify and classify recurring themes in wind turbine accident news, and association mining was applied to identify contextual terms associated with death and injury. The tabular and visual analyses relate accidents to location (offshore vs. onshore), wind turbine life cycle phases (transportation, construction, operation, and maintenance), and the incidence of death and injury. As one of the insights, more incidents were found to occur during operation and transportation. Through topic modeling, topics associated most with deaths and injuries were revealed. The results could benefit wind turbine manufacturers, service providers, energy companies, insurance companies, government bodies, non-profit organizations, researchers, and other stakeholders in the wind energy sector.
