The ship motion quiescent period is the period during which all ship motion is within acceptable limits to marine operations, such as helicopter landing and UUV handling. In most cases, a short time quiescent period would be sufficient to conduct a specific type of operation. In this paper, the feasibility of the quiescent period prediction through the simulation of ship motion in waves is analyzed, and it is concluded that there are three key phases of the quiescent period prediction： the measurement of waves, the measurement of wave propagation, and ship motion prediction. Finally, an outlook of the future of the quiescent period prediction is also provided.
