Abstract: In the present paper, the transient response of a merchant ship propulsion plant is investigated using a model implemented in the computational environment MATLAB/Simulink. The main engine of the vessel, which is considered to be of the two-stroke marine Diesel type, is modeled by the means of a quasi steady cycle mean value approach. According to that, two non-linear first order differential equations, which are derived by applying the angular momentum conservation in engine crankshaft and turbocharger shaft, are used for the calculation of engine crankshaft and turbocharger shaft rotational speeds. The other engine operating parameters are calculated after the solution of a non-linear algebraic system of three equations corresponding to the mass and energy balances in the engine components. In order to calculate the propeller thrust and torque, the polynomials for the propellers of the Wageningen B type are used. In addition, the ship velocity and the movement al!
ong its longitudinal axis are also calculated using the differential equation describing the ship surge dynamics. The engine model is validated against previously published experimental data. Then, the simulation of merchant ship propulsion plant under various operating conditions is performed and the derived results are presented and discussed.
