Abstract: The conflict in the use of sea area between the offshore wind power and the offshore oil-gas exploitation projects in the Bohai Sea is focused. The causes, characteristics and existing coordination mechanisms of their conflict in the use of sea area are analyzed and the feasible routes for their compatible development are discussed. The research indicates that although the modes of the sea area use are different between the offshore wind power and the offshore oil-gas exploitation projects, the characteristics of their use of sea area are similar. And the spatial overlap of the sea area used is the main reason for the conflict, which is particularly prominent in the Bohai Sea region and specifically shows as the overlapping of offshore wind farm sites with oil and gas safety operation zones and the crossing of cables and pipelines. It is evident that they have achieved a compatible development model by adjusting the layout of wind turbines, adopting high-capacity wind turbines, and signing strategic agreements based on the case analysis of the coordination between offshore wind power projects and marine oil and gas development projects in the Bohai Sea. This approach effectively mitigates the conflicts arising from the concurrent use of sea areas for offshore wind power and marine oil and gas development. This study can provide ideas and references for further promoting the development of offshore energy.
