Abstract

A method for automatically controlling the speed of a ship, in which the engine speed (nMOT) is automatically controlled by a closed-loop engine speed control system as an inner closed-loop control system, the ship's speed (vS) is automatically controlled by a closed-loop ship's speed control system as an outer closed-loop control system, and the ship's set speed (vSL) is influenced as a reference input of the closed-loop ship's speed control system as a function of an external signal source. The ship's set speed (vSL) is corrected as a function of the underwater topography (TOPO).
