The invention discloses a hydraulic system of a quick mooring device of an offshore operation helicopter and a control method. The system comprises an oil tank, a hydraulic pump, a motor, a one-way valve, a pressure sensor, a filter, an overflow valve, a two-position four-way electromagnetic reversing valve group, a three-position four-way Y-shaped hydraulic reversing valve, a stacked type double one-way throttle valve, a stacked type internal control hydraulic lock, an external control high-flow hydraulic lock, a safety valve, a cartridge valve, an energy accumulator, a pneumatic hydraulic pump and a thick and thin parallel single-rod hydraulic cylinder. And a mechanical claw unlocking cylinder, a middle-position lock unlocking cylinder and an emergency lock unlocking cylinder are arranged. The control method comprises conventional action control methods such as rapid capturing of the helicopter, straightening in the traction process, rapid releasing, transverse mechanical locking and transverse hydraulic locking, and a safety protection control method and an emergency action control method. According to the invention, all operation functions required by the rapid mooring device can be met when the offshore operation helicopter is recovered and released, and the operation safety is guaranteed to the greatest extent.
