Standards for ship manoeuvrability adopted by IMO (International Maritime Organization) requires that the manoeuvring performance of a newly designed ship complies with criteria for each performance index defined in the standards. Generally the manoeuvring performance of a ship is evaluated by sea trials. Manoeuvring trials should be conducted under the environmental conditions prescribed in the standards. As for wind and waves, it is required not to exceed Beaufort Scale 5 and sea state 4 respectively. However, even if trials was conducted in conditions within the limits, observed manoeuvring performance may have been influenced by the external disturbances and there is no established method to correct the influence of external disturbances. In this paper, the authors performed the numerical simulation of turning motion and zig-zag manoeuvre to evaluate the effect of external disturbances such as wind and waves on manoeuvring performances. From the investigation, it is clarified that influence on manoeuvring performance becomes smaller when a ship receives external disturbances from a bow.
