As the world economy recovers from the coronavirus pandemic, we used coal in large quantities to fuel economic growth. The issue of excessive carbon emissions is once again causing concern. In this context, how to cope with the risks faced by offshore wind power projects and choose the most favorable PPP project operation mode has become a hot research issue in the dual-carbon background. This study identifies risk factors for offshore wind power PPP projects and constructs an analytical hierarchical process consistent with a triangular ambiguity number for empowerment. The VIKOR hesitancy fuzzy multi-attribute method based on prospect theory is used for the terminal decision and comparative analysis. We have constructed a model of operational mode selection for PPP projects for offshore wind power generation and verified its practicality and scientificity through empirical calculations. This paper discusses and points out the rational progress model of future offshore wind power project PPP model and based on this maximizes the venture of offshore wind power PPP project. The above studies are expected to provide a useful reference for the reasonable burden of offshore wind PPP projects and the development of current energy sources in a low-carbon context.
