Abstract:
Provided is an operation control system capable of preventing undesired motion of a rudder plate driving unit. The operation control system is provided with a rudder plate driving unit, a hydraulic pump, a directional control valve, a shutoff mechanism, and a control device. Separately from the directional control valve, the shutoff mechanism is disposed between the hydraulic pump and the rudder plate driving unit, and stops the flow of a pressurized liquid being supplied from the hydraulic pump to the rudder plate driving unit by closing a point therebetween. The control device controls the shutoff mechanism such that, when a predetermined shutoff condition is satisfied, the shutoff mechanism stops the flow of the pressurized liquid being supplied from the hydraulic pump to the rudder plate driving unit.
