PURPOSE:To easily confirm the line configuration by providing a color display unit displaying an opened stevedoring system with the color corresponding to a cargo pump when a stevedoring system judging mechanism receives a valve switching signal from a sensor. CONSTITUTION:If switching valves (a), (m), (p), (d) are opened, an opening signal is sent to a line configuration data generating circuit 11 from an associated signal generator 4 and is further sent to a common line processing circuit 13. Next, the processing circuit 13 judges that a feed/discharge line is formed with a pipeline 7 of switching valves (a), (m), (p), (d) based on the information stored in a memory circuit 14 and determines to display the pipeline 7 from a cargo pump 6a, between the valve (a) and valve (m), between the valve (m) and valve (p), between the valve (p) and valve (d), and between the valve (d) and a connecting section 22 with the first color and further display these valves with the same color. The same decision is made for the line 7 and a valve 5. Next, the information signal of the portion to be displayed with the first color is sent to a generating circuit 15, and the line configuration with the first color can be displayed and confirmed on a color display unit 3.
