The reliabilities of the offshore wind turbine blades supported by the floating foundation are studied. The motion of the floating wind turbine is calculated by the Fast software, and the structure model of the blade is established by the Ansys software. The failure probabilities of the blade root overload, the blade root fatigue and the excessive displacement of the blade tip are calculated. The fixed wind turbine blades and the floating wind turbine blades are compared to investigate the influences of the floating foundation motion on the blade reliabilities. The results show that, the failure probability of blades supported by the floating foundation is greater than that supported by the fixed foundation. The floating wind turbine blades with different piezoelectric material are analyzed to investigate the influences of the piezoelectric material on the blade reliabilities. It is shown that for the blade with piezoelectric material, the stress of blade root and the displacement of blade tip both decrease, and the probabilities of fatigue failure and overloaded of the blade root decrease significantly.
