Offshore Wind Turbine Technology

This book provides a comprehensive overview of the development and challenges of offshore wind power generation. It emphasizes the significance of wind energy as a crucial element in China's energy transformation and its contribution to achieving the country's carbon peak and carbon neutrality targets. The book begins by introducing the current status of offshore wind power, highlighting its global expansion and China's leading position in installed capacity. It explores the complexities and unique environmental conditions associated with offshore wind farms, including the challenging construction and maintenance processes. The authors address the limitations of offshore wind resources, such as lower average wind speeds and extreme wind conditions, as well as the reliability issues of key components, resulting in higher electricity costs. With a focus on offshore wind turbine technology, the book covers various aspects, including design, structural foundations, construction techniques, operation, and maintenance. It delves into the coupling effects of wind and waves in the offshore environment and discusses the geological considerations specific to offshore wind farms. The book also touches upon industry standards, certifications, and the influence of offshore wind farms on marine ecosystems. This book serves as a valuable reference for engineering students specializing in offshore wind turbine technology and graduate researchers exploring this field. Moreover, it provides practical insights for professionals working in the wind energy industry. Selected sections of the book are also suitable for general readers interested in gaining knowledge about offshore wind power.

About the Author :
Mingwei Ge,  Ph.D., is a professor and serves vice dean of the School of New Energy at North China Electric Power University (NCEPU). Before joining NCEPU, he obtained his doctoral degree at Tsinghua University in 2011 and his Bachelor degree from Northwestern Polytechnical University in 2006. He has served as the guiding expert for the 2020 National Key Research and Development Program “Renewable Energy and Hydrogen Energy Technology” and has been elected as the secretary-general of the Youth Committee of the China Renewable Energy Society. He is also a member of the China Energy Terminology Review Committee and serves editorial board member for journals including IET Renewable Power Generation, Boundary-Layer Meteorology, and Electric Power Construction. Prof. Ge’s ongoing and future research advances fundamental understanding and engineering applications of flow physics including wind-turbine aerodynamics, wind-turbine wakes, and wind-farm flows. He has proposed an efficient low-load aerodynamic design methodology for large wind turbine blades and designed eight aerodynamic shapes of blades for 2.0 MW, 3.0 MW, and 5.5/7.0 MW wind turbines. This methodology has been applied for more than 10,000 blades production. The 76.6-meter offshore wind turbine blade was selected as the "Best Blade Award of 2018" by “Windpower Monthly” and was used in China’s first floating wind turbine prototype, "Three Gorges Leading". Additionally, he has developed a series of high-precision wake models and wind-farm flow analytical models, invented a micro-siting method for wind farms considering both fatigue damage and power generation, and proposed an intelligent operation and control method for wind farms. These research findings have been applied by large enterprises such as China Three Gorges Renewables and China Huaneng Group. Prof. Ge has led five national-level projects, including key projects in the state laboratory, project of the National Key R&D Program, the National Natural Science Foundation of China. He has been awarded as the Distinguished Young Scholars by the Beijing Natural Science Foundation. As the first or corresponding author, he has published more than 40 SCI papers in international authoritative journals, including Journal of Fluid Mechanics, Applied Energy, and Energy. He has held 17 authorized invention patents as the first inventor, has registered one software copyright, and has published two academic monographs. He has received several prestigious awards, including the National Teaching Achievement Second Prize, the Beijing Teaching Achievement First Prize, the Hebei Province Science and Technology Progress First Prize, the Capital Frontier Academic Achievement Award, and the Wu Zhonghua Outstanding Young Scholar Award. Li Li, Ph.D., is a professor at the School of New Energy, North China Electric Power University. She received her doctoral degree from the School of Energy and Power Engineering at Shandong University in 2010. Her main research focuses on intelligent wind farm technology. She has been responsible for one project funded by the National Natural Science Foundation of China, one sub-project of the National Key Research and Development Program, and several industry-sponsored projects. She has published over 20 SCI and EI-indexed papers. She received the first prize of the Science and Technology Award from the China Electrotechnical Society in 2018 and the second prize of the Electric Power Construction Science and Technology Progress Award in 2017. Meng Hang, Ph.D., is an associate professor at the School of New Energy, North China Electric Power University. He obtained his doctoral degree from the University of Waterloo in Canada in 2019. His research mainly focuses on the fluid-structure interaction of large wind turbine blades. He has participated as a key member in two projects of the National Key Research and Development Program and has published more than 20 SCI journal papers. Long Kai, Ph.D., serves an associate professor at the School of New Energy, North China Electric Power University. He received his doctoral degree from the School of Vehicle and Mechanical Engineering at Beijing Institute of Technology in 2007. His primary research concentrates on structural simulation and optimization of wind turbines. He has been financed by  the National Natural Science Foundation of China, along with several industry-sponsored projects. He has published more than 80 SCI papers and 3 monographs.
