REDUCING THE STOPPING DISTANCE OF DEEP SEA VESSELS

This report analyses the emergency stopping manoeuvre of a containership whereby fundamental thoughts regarding the forces and moments on the coupled systems of ship and engine are necessary. The stopping time and the stopping distance are dependent on the ship's mass, the resistance of the hull, the propeller and propulsion unit. Therefore the following factors govern the process of stopping a ship: kinetic energy of the moving ship, kinetic energy of the rotating propeller, resistance of the hull and friction work of the propulsion unit. It seems that in recent years a change for the worse with respect to an emergency manoeuvre of a ship has occurred. A reason for this may be the increase of the power concentration on the propulsion engines. Changes on the system 'engine' are therefore suggested which finally can lead to a possible improvement of the emergency stopping manoeuvre.
