The invention provides a method for optimizing a container ship fairing based on CFD (computational fluid dynamics) analysis, which comprises the following steps of: displaying surface wind pressure distribution and surrounding space flow fields of the fairing and a container ship by CFD, detecting wind resistance of a ship body, creating dimensionless coefficients, comparing the dimensionless coefficients of the container ship and the container ship with the fairing, and determining whether the fairing is optimized or not. The flow guide cover reducing wind resistance by at least 10% and structural parameters of the flow guide cover are obtained, and repeatability is good; a wind tunnel test verifies that the reliability is high; the CFD simulation can reduce the research and development cost, save the research and development time and improve the research and development efficiency of the container ship fairing. The fairing is arranged along the bulwark of the container, the deck covering area is small, and the weight and the wind resistance reducing effect are both considered; the fairing is simple in structure, low in manufacturing cost, convenient to machine and install, free of influence on mooring arrangement, good in compatibility and capable of being used for new ship manufacturing and old ship refitting. Wind resistance is effectively reduced, impact of waves on containers and shipborne equipment can be resisted, wave blocking walls are omitted, and shipbuilding cost is saved.
