The invention discloses a floating wind power mooring cable monitoring method, which comprises the following steps: S1, acquiring six-degree-of-freedom response data of a floating body platform, S2, establishing a relative coordinate system by taking the center of the floating body platform as an original point, S3, calculating the horizontal projection of the whole catenary and the height from the fairlead end of the catenary to the seabed, and S4, calculating the height of the whole catenary and the height of the fairlead end of the catenary to the seabed. S4, establishing a mathematical model between the motion of the floating body platform and the mooring tension according to a catenary mooring force calculation formula, and calculating the tension data of the mooring anchor chain according to the mathematical model; the method comprises the steps of S1, obtaining tension data measured by a one-way tension meter and tension data calculated according to a mathematical model, S6, conducting mutual verification on the tension data measured by the one-way tension meter and the tension data calculated according to the mathematical model, S7, obtaining transverse deformation data, measured by an underwater tension meter, of the mooring anchor chain, and S8, obtaining the overall stress condition of the mooring anchor chain according to the tension data obtained by the mathematical model and the transverse deformation data measured by the underwater tension meter. According to the invention, the measurement precision and reliability can be improved, and the long-time monitoring of the whole mooring system is realized.
