The invention discloses an offshore power supply system, comprising a floating shell, a transmission part and a piezoelectric sheet. The transmission part comprises a central shaft, a transmission shaft, a sleeve and a universal rotary joint; The piezoelectric sheet comprises a piezoelectric transducer sheet and a conductive sheet; The floating shell and the central shaft are connected and relatively fixed through a spring, and the end of the transmission shaft is inserted into the sleeve so as to transfer the center deviation action of the central shaft to the piezoelectric plate. When the floating shell is inclined by the action of the sea wave, the central shaft is inclined and positive pressure is applied to the piezoelectric plate through the restriction of the sleeve to generate electric energy. The invention also discloses a power supply method based on the offshore power supply system, which controls the output power by changing the number of piezoelectric sheets and the quality of the central axis.
