| Research Abstract |
The purpose of this study is to develop a practical prediction method for ship manoeuvring performance. In order to accomplish this purpose, the precision of the prediction method for hydrodynamic forces has to be improved and the interference coefficient between a hull, a propeller, and a rudder needs more consideration. In 1997, for the purpose of getting the hydrodynamic data, the captive model test was carried out at the ship manoeuvring basin in Kyushu University. The surge force, sway force and yaw moment acting on a ship was obtained. In 1998, the theoretical prediction method for the hydrodynamic forces was investigated by using these experimental data. As a result, a prediction method showed a fine result for the ordinary manoeuvring motion. The mathematical model was also investigated for a special situation that a ship has large drift angle. In 1999, the new practical prediction method for ship manoeuvring performance was investigated from these former results. As a result, a simple approximation method was obtained for the ships with unsteady course keeping ability. Though the ordinary method could not show the difference of the effect of the stern body shape for manoeuvring motion, this new approximation method can show the effect of the stern shape even if the ships have same principal dimension.
As these result shows, this study achieved the first purpose to obtain the practical prediction method for ship manoeuvring performance.
