The invention provides a vibration reduction method and system for a ship water diversion port, and relates to the technical field of ship control, and the method comprises the steps: obtaining the overall vibration intensity value of the ship water diversion port corresponding to a plurality of piezoelectric vibration reduction circuits under the current working condition; each piezoelectric vibration reduction circuit is formed by combining piezoelectric patches laid on the inner wall of the ship water diversion port and different numbers of energy consumption units; according to the overall vibration intensity value, determining an optimal piezoelectric vibration reduction circuit corresponding to the current working condition in the plurality of piezoelectric vibration reduction circuits; and based on the optimal piezoelectric vibration reduction circuit, vibration reduction is carried out on the vibration intensity at the water diversion port of the ship. The current piezoelectric vibration reduction circuit under different working conditions can be adaptively adjusted to be the optimal piezoelectric vibration reduction circuit, so that the water diversion port of the ship can keep low vibration strength under different working conditions, the problem of structural fatigue of the water diversion port is effectively relieved, the applicability is high, and the vibration reduction effect is effectively enhanced.
