Development of Simulation Model for Engine Analysis Considering Ship Motion -1st Report: Construction of Engine Model, and Relationship between Control Period and Fuel Consumption Rate

Abstract

 As environmental problems have become serious in recent years, calls for energy savings in marine vessels have been made. This paper proposes a mathematical model for the dynamic simulation of ship propulsion systems. The model was implemented and solved using the computational environment MATLAB Simulink. In this model, various elements of the system were described as individual blocks linked together to take into account interactions between them. The behaviors and performances of individual components of the system were statically and dynamically analyzed and evaluated. From the simulation results, it was clarified that the disturbance cycle influences the fuel consumption rate of the engine.
