Abstract
PURPOSE: To safely load and unload freights and to prevent ramp way from twisting by exactly and rapidly controlling the attitude of a hull to restrict the inclined angle of the ramp way and the longitudinally inclined angle of the hull lower than predetermined value.
CONSTITUTION: The longitudinal and lateral inclination angles of the hull are detected by a detector 44, and the inclined angle of the ramp way installed at the hull is detected by a detector 46. The longiudinal and lateral inclination of the hull and the inclination of the ramp way are judged via comparators 49, 50, 54, 55 whether they are within allowable range or not. If the inclined angle exceeds the allowable range, a logic circuit is operated to control the ballast tank pouring and discharging units 56, 57, 58, 59 of the hull so as to control the inclination of the hull.
