Development of an Experimental Methodology for Self-Propulsion Test with a Marine Diesel Engine Simulator, the Fourth Report: Direct Measurement of Actual Ship Speed in Waves by Model Tests

Authors continued to develop and expand new experimental methodology on tank model test with the MDES (Marine Diesel Engine Simulator) and the ATS (Auxiliary Thruster System), for making evaluation techniques on actual ship performance in waves more sophisticated. In this fourth report, the methodology is so enhanced that measured results of model test can be directly evaluated as the actual ship performance in waves. Here, the details of the newly expanded methodology are introduced, and experimental results measured from the free running model tests in waves with the expanded methodology are validated, even focusing on behaviors of ship diesel engine.
