Offshore wind power has the advantages of high energy density, low wind curtailment rate and small impact on the environment. It has great development potential and can provide a strong guarantee for China to achieve the goals of carbon peaking and carbon neutrality. By 2022, China's cumulative grid-connected installed capacity of offshore wind power has exceeded 30 GW, continuously ranking first in the world. In June 2022, nine departments including the National Development and Reform Commission and the National Energy Administration jointly issued the 14th Five-Year Plan for Renewable Energy Development, clearly stating that: We should optimize the layout of offshore wind power, make deep-sea offshore wind power planning, focus on building five major offshore wind power base clusters in Shandong Peninsula, Yangtze River Delta, Southern Fujian, Eastern Guangdong and Beibu Gulf, and strive to achieve a cumulative installed capacity of offshore wind power exceeding 200 GW by 2030. By promoting the innovation and demonstration application of deep-sea floating wind turbine foundation and offshore VSC-HVDC transmission technology, we are striving to commence the construction of China's first floating commercial offshore wind power project during the "14th Five-Year Plan". However, China's offshore wind power industry is still in its infancy, and there are still problems such as excessive LCOE and imperfect policy system, which seriously restrict the scale development of offshore wind power.In this context, the journal Southern Energy Construction has planned a special issue on "Offshore Wind Power Engineering Technology" in July 2023 to closely track relevant hot spots and industry trends such as offshore wind power operation and maintenance strategies, offshore wind power construction and installation technologies in China's offshore wind power industry. Front-line teachers from universities and colleges, front-line engineers from enterprises and R&D personnel were sincerely invited to share the latest research results and industry trends, including 18 high-level papers, which cover the theory, technology and application in the fields of offshore wind power installation ships, offshore wind power foundation type-selection design, offshore step-up substations, offshore wind power and offshore hydrogen production. We hope to provide useful ideas and references for the high-quality and sustainable development of China's offshore wind power industry through the burst of thinking sparks in this issue.We sincerely thank the authors, peer reviewers and readers for their support to this issue. We hope that the publication of this issue can provide reference for experts and scholars from all walks of life who are concerned about and engaged in relevant research, so as to promote the rapid development of basic theory and key application technologies in the field of offshore wind power.
