around a ship's hull

It is well known that ship manoeuvrability changes considerably with hull forms, and the manoeuvring characteristics are different depending on loading conditions or environmental conditions. Furthermore, ships sailing at sea are under the influence of external disturbances such as wind, wave and current.
Understanding the dynamic characteristics of ships is very important for safe navigation or operation at sea. Predicting the motion of a ship based on numerical simulation is one of the effective methods for evaluating the performance of ships in various conditions. It is required to evaluate the hydrodynamic forces such as the lateral force and yawing moment acting on ship's hull with high accuracy, because they have a great influence on manoeuvring performance. Our laboratory mainly covers the dynamics and control of ships and floating bodies. We are doing research on the prediction method of ship manoeuvring motion both experimentally and theoretically and developing a calculation code for the prediction of hydrodynamic forces acting on a floating body. Furthermore, the development of navigation support systems or automatically navigated ships will be achieved by investigating the dynamic characteristics of ships in detail.
