ABSTRACT:
In order to automatically position a ship which is subjected to external disturbance forces and which is provided with propulsion units arranged to orient the ship in the direction of the resultant of such disturbance forces, there is derived a representation of a control value from the sum of the representations of the actual transverse forces acting on the ship, the control value representation is compared with a representation of a given nominal value, and the control value is brought to zero on the basis of the result of such comparison.
