This Paper chooses variable displacement motor as the driving unit for underwater winch. Based on that, a complete hydraulic control circuit is proposed. The oil circuit can realize the active cable picking and laying automatically. Meanwhile, the motor can be adjusted with infinitely variable speed function. In order to save energy, an automatic unloading circuit is designed. At the same time, considering the complex underwater working environment and bad working conditions, hydraulic clutch is introduced to increase the function of cable passive releasing. The hydraulic circuit has fast response and high fault tolerance, which not only ensures the underwater winch to complete various operations quickly and effectively,but also ensures the safety of all parts of the winch.
