Abstract

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.

Highlights

  • No accident that was caused by an earthquake was found, 15 and six onshore wind power accidents that had been caused by typhoons and hurricanes, respectively, were found. These findings indicate that strong gusts that are caused by tropical cyclones directly affect wind turbines

  • Based on the results of the interview questionnaire, the seven scores for each risk factor were summed and averaged; the resulting mean represented the average score from all participants

  • Typical risk management steps were taken in this work, relevant risks were identified, risk factors were categorized by their attributes, and the risk breakdown structure (RBS) was established

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Taiwan has for long time depended on imported fossil fuels to generate power, causing increasingly severe air pollution in the country. To increase renewable energy usage and mitigate air pollution, the government proposed the Four-Year Plan for the Promotion of. According to the latest statistics from 4C Offshore, an international offshore wind power (OWP) consultancy, the best offshore windfarms of the world are almost all located in the Taiwan Strait [1]. Such favorable natural conditions around Taiwan has increased the government’s determination to develop OWP
