실습선 백경호의 조종성능 평가 = Evaluation of the maneuverability of the fisheries training ship Baek-Kyung

국문 초록 (Abstract)

이 연구의 대상선인 부경대학교 실습선 백경호는 수선간장 85m로써 IMO 조종성능 기준이 적용되는 선박이 아니다. 그러나 정원이 160명이나 승선하기 때문에 선박의 조종성능 특성을 이해하는 것은 안전 운항에 필수 요소일 것이다. 그러한 의미에서 대상선이 실시하였던 해상 시험 결과를 IMO 조종 성능 기준에 의거하여 분석하는 연구를 수행하였다. Turning tests 결과는 기준을 잘 만족하였고, Zig-Zag tests 결과 10°/10°에서는 first over shoot angle이 기준을 초과하였고, 20°/20°에서는 1.8° 차이로 만족하였다. 추가적으로 침로 안정성 판별식을 이용하여 수치 계산한 결과 –0.0051로 침로 불안정으로 판별되었다. Stopping tests 결과는 기준을 잘 만족하였다. 연구 결과로부터 분석된 대상선의 조종성능 특성이 조선자의 안전 운항에 도움이 될 수 있기를 기대한다.

다국어 초록 (Multilingual Abstract)

The model ship of this study, the Baek-Kyung fisheries training ship of Pukyong National University, has a length between perpendiculars of 85 meters, making it not subject to the IMO maneuverability standards. However, understanding the maneuvering characteristics of the vessel is essential for safe navigation. In this regard, this study was conducted to analyze the results from the sea trials of the model ship conducted in accordance with the IMO maneuverability standards. The results of the turning tests met the standards well while in the zig-zag tests, the first overshoot angle exceeded the standard in the 10°/10° test; however, such results met with a difference of 1.8° in the 20°/20° test. Additionally, using the course-stability discrimination formula, the calculated value was -0.0051, indicating unstable course-stability. The results of the stopping tests met the standards well. It is hoped that the analyzed maneuvering characteristics of the model ship from the study results will contribute to the safety of ship navigation.
