In the case where a ship runs in waves with turning maneuver, the rolling oscillation becomes apparently unsteady state due to the changes of the frequencies and angle of the encounter waves and can grow into large amplitude. Especially in severe sea condition, operators are demanded to predict the large waves that faces during and after turning maneuver to avoid the serious impact for stability. It is, however, very difficult in practice. In the 1st report, the authors studied the characteristics of unsteady rolling during turn in regular waves and consequently showed some parameters that effect to maximum heel angle. Since the 1st report, we have tried to develop a practical system to predict the encounter waves and ship motion to assist the wave-avoidance-maneuver and accomplished the most part of it. Our latest system consists of wave radar and numerical motion simulation technique. So, this reports shows the outline of this system and some results of motion prediction. Additionally, the results of field tests are shown for validation of this system.
