To provide a suspended load oscillation suppression method and a suspended load oscillation suppression system which are capable of reducing the oscillation of a suspended load, suspended from a floating crane with a simple structure without being restricted by the size of the floating crane or the weight of the suspended load, and the like.SOLUTION: A suspended load oscillation suppression method includes a wave height measurement step of measuring the height and a cycle of a wave, a hull oscillation calculation step of calculating the oscillation amount of a hull which is the oscillation amount of a floating crane 3 based on the wave height and the cycle, a suspended load oscillation calculation step of calculating the oscillation amount of the suspended load which is the oscillation amount of a pile 2 based on the hull oscillation amount, and an oscillation reduction step of vertically moving a weight suspended from a crane 31 between a tip of the crane 31 and the pile 2 in accordance with the oscillation amount of the suspended load.SELECTED DRAWING: Figure 2
