We made a small model of a medium-size bulk carrier together with small twin podded propellers and a dynamometer to measure only the thrust of the podded propeller. In order to obtain the propulsive performance, we performed various experiments at Kyushu University, such as resistance test, P.O.T, propeller tests with dummy pod system and with real pod system (pusher and tractor types) and the load varying tests. From the obtained results, we analyzed the propulsive performance by the combined use of various results. In analysis, the pod and strut can be treated as appendages of the hull or parts of the propulsor. We showed both results and discussed on the suitability of the methods. On the other hand, we performed theoretical calculations corresponding to the above experiments to obtain the propulsive performance of the model ship by using a surface panel code "QSCM" which was developed at Kyushu University. We also showed the results of a virtual full-scale ship and compared them with the results of propulsive performance obtained by ITTC 1978 Prediction Method. By these approaches, we attempted to clarify the mechanism of the propulsive performance of the ship model with small twin podded propellers.
