Ocean current power generation is considered as one of the promising marine renewable energies. In this paper a floating type device is adopted because it is advantageous in respect to cost and maintenance. It is supposed that the floating current turbine is shaken by non-uniform flow. Thus, we investigated the motion of the device. The results indicate that the influence of vertical profile is small, but that of surface waves and turbulence is not small in some cases. Therefore, it is necessary to gather more observation data to come to the final conclusion on the motion in non-uniform flow.
