The controllable pitch propeller has been traditionally used in various types of ice-going vessels. It is well established that the CP propeller can cope with variations in torque and rpm caused by ice, through adjustments of the propeller pitch, thus maintaining the torque and rpm so that the propelling machinery is hardly affected. With direct or geared diesel drive it is important that over-torque and a drop in shaft speed are avoided. Constantly maintained highest permissible power level will not only increase the average speed of the ship in varying ice conditions, but will also increase its ice-breaking capability.
