When a ship is saling on waves the relative motions occur which result in propeller emergence, and as a consequence – propeller thrust reduction which results in a decrease in the ship’s speed. Propeller emergence is also accompanied by the decrease in torque values, with which the propeller affects the marine engine. The article presents both calculation results and the algorithm for calculating the decrease in torque of the propeller during ship motions on irregular wave.
