Abstract

At the design stage, it is very important to know the ship maneuvering characteristics from the view point of ship performance and for the safety of navigation. IMO only gives some criteria for ships in full load even keel condition. However, the ship generally is operated not only in full load condition but also in half load condition or ballast condition. Therefore we must estimate the ship maneuvering in different loading condition to ensure that the ship will satisfy with IMO rules and navigate safely in every condition. In this paper, we have investigated the maneuvering characteristics of a ship by simulation and experiments with real ship. By comparing with the results of simulation, the real ship tests conform with simulation test and previous researches. Therefore, the method base on real data is well done to estimate the ship maneuvering in different loading conditions. The change of ship's manoeuverability accoriding to ship's operation conditions was estimated.

선박 성능과 항해 안전의 관점에서 선박조종 특성을 아는 것은 선박 설계에서 중요한 일이다. IMO 규정에 의하면 만재 적하된 even 조건(트림=0)에서 몇가지 선박 조종 기준이 제시되어 있다. 그러나 선박은 일반적으로 항상 만재 적재 조건으로 운항되지 않는다. 따라서 선박이 IMO 규정을 만족시키고, 모든 적재 조건에서 안전하게 항행하도록 하기 위해 다양한 적재 조건에서 선박 조종 특성을 추정해야 한다. 본 논문에서 우리는 실선 실험과 시뮬레이션을 수행하여 조종특성을 조사하였다. 시뮬레이션 결과와 비교하였을 때 실선실험은 시뮬레이션 값 및 이전 연구와 그 경향이 일치한다. 실 해역에서 얻은 조종실험 데이터가 선박 조종성능 추정에 활용 될 수 있음을 확인하였고, 실시한 실해역 실험을 통하여, 선박 운항 상태에 따른 조종성의 변화를 추정할 수 있었다.
