Abstract: With the exploitation of offshore wind power moving to the deep sea, the floating offshore wind turbine （FOWT） structure is regarded as the more competitive solution. Because of its harsh marine environment and high construction cost, how to evaluate the design of FOWT structure reasonably has got attention to the industry. In this paper, a multi-criteria evaluation system for FOWT schemes is established from the perspectives of function, safety and economy, and related evaluation indexes are defined. Based on the Entropy-TOPSIS （Technique for Order Preference by Similarity to an Ideal Solution） method, a multi-criteria evaluation model for FOWT is established. Two submersible FOWT structures are applied to illustrate the proposed evaluation model. Through case analysis, it is proved that the evaluation model can evaluate FOWT schemes from an objective point of view. The optimization suggestion proposed based on the evaluation model can help to improve the comprehensive performance of the scheme.
