Offshore wind power is a major potential direction for ensuring energy security, achieving carbon neutrality goals, and fostering the marine economy. While a single development model can't meet the requirements of three-dimensional development of marine resources and industrial synergy, integrated development of offshore wind power with other offshore energies and resources is becoming the trend for future. This study analyzes the advantages regarding the multi-energy integrated development of offshore wind power in China, reviews the characteristics, domestic and international development trends, and challenges of six foundational models, including integration with offshore oil and gas, hydrogen, photovoltaic, wave energy, marine ranching, as well as integrated energy island. Key conditions for the integrated development are summarized, a decision-making process is established, and future strategic objectives and policy recommendations are proposed. The study suggests that at the resource level, planning guidance should be strengthened to coordinate the opening and development layout of national jurisdictional waters for wind power, while ensuring that development planning is effectively carried out based on the overlapping distribution of resources. At the technical level, efforts should be made for developing key technologies for multi-energy integration, such as offshore hydrogen energy production, storage, and transportation, as well as microgrid dynamic regulation. At the economic level, it is necessary to strengthen industrial collaboration and reduce development costs through multiple strategies such as modularization, standardized construction, and industrial alliances.
