Abstract
In order to expand work time window under high sea state, hydrostatic secondary control was proposed to winch system of ship-mounted crane to reduce influence of vessel motion. System models of passive and active heave compensation mode were simulated. Cascade control strategies based on conventional PID and fuzzy PID were used to active heave compensation (AHC) system. As a result, approximate 90 percent of vessel motion was eliminated for payload.
