Abstract

The ship manoeuvring test using an approach of the free running model on the open water pool is described. In this test, the most important part is to retrieve a trajectory data of the model ship while it does manoeuvre. It is necessary to have an accurate technique of the data retrieval during the test. A technique of image processing is proposed in this paper with the aim to analyse the ship manoeuvring path. In this method, the manoeuvring test of the model is recorded with the camera, and the movie result is then analysed with the movie maker software to get the trajectory points for a second step. The 6500 DWT tanker with a 1:85 scale model is tested on the turning test with the two different type of rudder namely the conventional and the single flap. The test results are obtained in terms of parameters including advances, transverse, tactical diameter and turning radius. The comparison results show the ship with single flap give better the manoeuvring performance with reducing turning diameter about 13.04% and 14.5% for the turning of Portside and Starboard respectively.
