The invention relates to a self-balancing compensation system, a marine crane and a control method thereof, and belongs to the field of mechanical engineering. The self-balancing compensation system includes a crane cylinder, an attitude acquisition system and an oil cylinder compensation system. The attitude acquisition system comprises an inclination angle sensor and a controller; the inclination angle sensor is used to measure the bidirectional inclination angles of a lifting straight arm relative to the X-axis and Y-axis of the horizontal plane; the controller is for real-time acquisition of the inclination angle signal measured by the inclination angle sensor, and processes the inclination angle signal into a control signal and outputs the inclination angle signal to the oil cylinder compensation system; the oil cylinder compensation system includes a first storage device, a second storage unit, a proportional reversing valve, a hydraulic control one-way valve, a one-way throttle valve, a one-way balancing valves, a hydraulic pump and a one-way valve; and the proportional reversing valve based on the received control signal controls the stretching or shrinking of the crane oil cylinder through left and right commutation, so as to ensure the normal working of the crane under terrible sea conditions. The system can realize safe working of the marine crane under sea conditions of grade 4-6.
