ABSTRACT:
The position of a ship moored by at least three anchor ropes extending between the ship and independent remote anchor points is corrected by a control system comprising a rope orientation angle detector, a device for designating the angle and amount of movement of the ship which are necessary to correct the position of the ship, a position correction parameter designating device which determines whether parallel movement or swinging movement is to be made to correct the position of the ship and sends the result of determination to the rope orientation angle detector, a deviation operator which compares the angle of movement with the rope orientation angle for producing an output corresponding to the differential angle, a rope extension and contraction control device responsive to the outputs from the deviation operator and the rope orientation angle detector for producing an output for commanding paying out or taking up of respective anchor ropes, and winches mounted on the ship for operating respective anchor ropes and controlled by the output from the rope extension and contraction control device which includes a device for increasing or decreasing the length of each anchor rope by one unit length and a device for controlling the next unit length when each rope is stabilized after completion of the control of the first unit length thereby moving the ship to a position designated by the rope orientation angle detector in accordance with the determination made by the position correction parameter designating device.
