Against the background of profound transformations in the global energy landscape and China's critical stage of energy transition, the coordinated development of offshore wind power and oil and gas fields has emerged as an important pathway to promote the efficient and integrated utilization of marine energy and to support the achievement of the "carbon peaking and carbon neutrality goals". This study first conducts a systematic assessment of the resource distribution of offshore wind power and oil and gas fields in China, analyzing the resource endowments of the Bohai Sea, East China Sea, and South China Sea. It summarizes the advantages of coordinated development, including spatial overlap of resource distribution, similarity in technical equipment, interconnection of infrastructure, and alignment of development objectives. Subsequently, the current status and typical cases of coordinated offshore wind power and oil and gas development in China and abroad are reviewed, verifying the technical feasibility of such integration. Three major application scenarios suitable for China are proposed: nearshore wind power combined with onshore power supply, deep and far-sea wind power, and special development modes. These scenarios are adapted to different marine conditions, each with distinct levels of technological maturity and development priorities. Furthermore, five key technologies—such as microgrid technologies for integrated offshore wind and oil and gas systems—are identified as core supports for coordinated development. Finally, this study proposes long-term development goals across three stages: theoretical research, engineering demonstration, and large-scale application. Policy recommendations are provided from the perspectives of resources, technology, and economics, offering both theoretical and practical support for the large-scale and commercial advancement of coordinated offshore wind power and oil and gas development in China.
