Zusammenfassung:	The invention relates to a winch control device for a deep-water dynamic positioning crude oil cargo transfer vessel. By the design of three key control components of main 5 controller, hydraulic transformer controller and direct-driven pump source controller, when the operating platform rises, the direct-driven pump source unloads, and the gravitational potential energy of the load is recovered into the accumulator through the hydraulic transformer, when the operating platform sinks, the direct-driven pump source and the hydraulic transformer supply oil to an actuator to release the recovered energy, 10 which greatly reduces the power consumption of the system, realizes the reasonable ﬂow distribution and smooth switching between the direct-driven pump source and the hydraulic transformer and solves the control problem of the hydraulic transformer. Based on the above, the invention can provide a stable and reliable winch control device for the deep-water power positioning crude oil cargo transfer vessel, and then realize the 15 heave compensation function of the winch system for the deep-water power positioning crude oil cargo transfer vessel, ensuring the stable operation of the winch system for the deep-water power positioning crude oil cargo transfer vessel.
