Abstract
Obtaining the effect of regular transverse wave is very significant for it is dangerous for ships to turn in transvers waves. To study ships motion law in regular transverse waves, computer simulation method was used. The simulation were based on ship mathematical model,called MMG(Maneuvering Model Group), and a waveforce mathematical model. In the simulation, the ship sailed in regular waves and calm sea with 0°and 20°rudder angle and the tracks were recorded. Hence, a ship trail was made to verify the truthfulness of simulation result. After analysing the simulation result, there is a diccussion to design a rudder controller, which can reduce the effect of waves. In conclusion, the effect of regular transverse wave on ship turning maneuverablity is obtained and it is feasible to design a rudder controller to reduce the effect.
