This paper presents a detailed mathematical model of ship propulsion system including slow speed diesel engine, screw propeller and governor. This mathematical model is then employed to investigate the system performances both in steady state and unsteady states. The simulation results are checked and the model is verified using experimental data. Next an original method for the system sensitivity analysis against changing of parameters is given. This method is finally applied for investigating the influence of degree of reaction of turbine of turbocharger on the system behaviour.
