Study on a procedure for propulsive performance prediction for CRP-POD systems

摘要

The experimental procedure to predict the full-scale performance of the CRP-POD propulsion system is studied. In the CRP-POD system, the RPM ratio of the two propellers is not mechanically fixed, in contrast with conventional CRP systems. Therefore the existing procedure for conventional CRP systems is not appropriate for evaluating the performance of each propeller. In this paper, the characteristics of the CRP-POD system, designed for a 9,600 TEU class container carrier, are studied experimentally. Based on this study, a procedure for propulsive performance prediction for CRP-POD propulsion ships is suggested.
