- it may have a function of transmitting, by wireless communication, information on an image of the vicinity of the draft, the inclination of the ship 2, the draft on the shore side, and the draft on the sea side to another computer device.
- the other computer device is not particularly limited, but a portable terminal such as a smartphone or a tablet terminal can be used.
- a portable terminal such as a smartphone or a tablet terminal
- the information transmitted from the computer device 3 can be confirmed on the display screen of the smartphone or the tablet terminal. It is possible to supervise the loading and unloading of cargo while grasping the draft and the amount of cargo to be loaded.
