PURPOSE:To promptly confirm the configuration of stevedoring systems and attain safe marine stevedoring by providing a display unit emphatically displaying those opened among multiple stevedoring systems when a stevedoring system judging mechanism receives valve switching signals from sensors. CONSTITUTION:When a valve switching control unit 2 receives a switching command input from an operation panel 1 and drives stevedoring valves 3A-3D of a controlled pipeline system, the opened/closed status of the valves 3A-3D is detected by a switching signal input unit 4, the valve opened/closed status data entered by feedback is stored in a memory unit 6, and if only the stevedoring valve 3B of the pipeline system 3 is opened, the data is processed by a compounding unit 5 and displayed on a CRT display unit 9. Next, if the unit 5 refers to an adjacent valve-related memory unit 7 and checks that the valves 3A, 3C, 3D adjacent to the valve 3B are opened, the pipeline data corresponding to a pair of adjacent opened valves is searched from a memory unit 9 of data of pipelines 3a-3g, and the corresponding color is emphatically displayed per system on the display unit 9 via a color code memory unit per system 10.
