| Research Abstract |
From the safety of nevigation in the crowding sea with many ships such as the canal, harbor and bay, it will be of most improtance to improve the ship manoeuvring performance.
The aim of this research is to predict the ship manoeuvr ability with high accuracy, and to solve the problem of manoeuvring performance. In general, the manoeuvr ability of ship will depend on closely her loading condition. The first results of this research makes clear the characteristics of ship manoeuvring performance such as a turning ability and zig-zag manoeuver in full load condition, half load condition, ballast and trimmed conditions. From these investigations, the prediction method for ship manoeuvring performance has been developed at the design stage.
In the second, the turning stopping manoeuver es caused by the unbalanced hydrodynamic force acting on hull, propeller and rudder. The second result investigates the mechanism of the turning motion during stopping with the reverse revolution of propeller.
As the last result, the research got the permissible limitation of the course stagbility, especially unstable ship, form viewpoint of the pilot manoeuvre.
