Outline of Final Research Achievements	In this study, a marine diesel engine simulator: MDS was developed for the self-propulsion test of model ships in waves. MDS is a real-time control system of propeller rotating speed, which reflects the characteristics of a marine diesel engine. MDS is composed of servomotor, dynamometer and controller in which mathematical model of 2 stroke low speed diesel engine with turbo charger is installed. Using MDS, we can measure ship speed, propeller thrust, torque and rotating speed coupled with the engine by model experiment in waves. Using MDS and auxiliary thruster also developed in this study, the authors conducted a self-propulsion test of a model ship in waves and measured not only ship motion responses but also the realistic dynamic responses of a ship propulsion system in waves such as propeller load and rotating speed fluctuation, fuel supply rate, etc. By this feature, the applicability of MDS for the design of engine control system was also confirmed.
