In order to study the attenuation motion characteristics and irregular wave response of the floating tidal power generation device with vertical-axis tidal turbine, the experimental model is designed and mooring test platform is built to conduct the free attenuation test, mooring attenuation test and irregular waves response test based on the mooring trial carried out in ship model test towing tank. The model＇s shaking attenuation characteristics is measured in attenuation test and also the tensile response of mooring line and shaking response of the combined model are measured in irregular wave response test. Finally the attenuation motion characteristics of the floating tidal power device is acquired and the tensile response of mooring line 1 and shaking response of combined model under the four-grade oceanic condition when the flow velocity is 0.6m/s are achieved which can provide the reference to theoretical research and engineering application of the floating tidal power device with vertical-axis tidal turbine.
