The invention discloses an active heave compensation device for an air winch and a control method thereof. The active heave compensation device comprises a winch status detector, a flow and direction regulator and a heave compensation controller; the winch status detector comprises an acceleration sensor, an inclination sensor, a cable length sensor, a tension sensor and the like; the heave compensation controller is a core part of the whole device and composed of a CPU module, a communication module, an A/D acquisition module and a D/A output module; the flow and direction regulator is mounted at the front end of an air inlet of a pneumatic motor on the air winch, and composed of an air suction switching valve, a flow proportional regulating valve, a flow sensor, a cable retracting switching valve and a cable deploying switching valve. The active heave compensation device for the air winch is reasonable in structural design, and may control deploying and retracting of a cable and heave compensation for the air winch through the controller, and thus is suitable for operations of ocean platforms and port wharfs; as a result, the work fields of the air winch are expanded.
