실선시험에 의한 DWT 8,000톤 선박의 조종성능 – Semi–balanced rudder and flap rudder –

초록

This study is intended to provide navigator with specific information necessary to assist the avoidance of collision and the operation of ships to evaluate the maneuverability of dead weight tonnage 8,000 tons Oil/Chemical tanker. The actual maneuvering characteristics of ship can be adequately judged from the results of typical ship trials. Author carried out sea trials based full scale for turning test, Z” maneuvering test, man overboard rescue maneuver test, inertia stopping test. Consequently, 2st Overshoot yaw angle of the semi balanced rudder and flap rudder in ±20° zig–zag test showed 22.2° and 18.0°, respectively. The maneuverability of the vessel was good in the flap rudder. The man overboard rescue maneuver maneuverability test was most favorable in the flap rudder and the full load condition. The results from tests could be compared directly with the standards of maneuverability of IMO and consequently the maneuvering qualities of the ship is e standards of maneuverability of IMO and consequently the maneuvering qualities of the ship isfull satisfied with its.
