To maximize electric power production using wave energy extractions from resonance power buoys, themaximum motion displacement spectra of the buoys can primarily be obtained under a given wave condition. In thisstudy, wave spectra observed in shoaling water were formulated. Target resonance frequencies were established fromthe arithmetic means of modal frequency bands and the peak frequencies. The motion characteristics of the circularcylindrical power buoys with corresponding drafts were then calculated using numerical models without consideringPTO damping force. Results showed that the heave motions of the power buoys in shoaling waters with insufficientdrafts produced greater amplification effects than those in deep seas with sufficient drafts.
