한국 연안의 각 항로에 취항하고 있는 대표적인 선형의 여객선들을 대상으로, 각 선형별로 선체운동 계산, 내항성능을 분석하여 선박의 안전성을 평가하였다. 이를 위하여 선박의 안전운항과 가장 밀접한 관련을 갖는 바람과 파랑을 주요 해역별로 비교 분석하였다. 이러한 기강정보를 입력요소로 하여 주요해역을 항행하는 대표적인 선형의 여객선들에 대하여 수치 시뮬레이션을 실시하여 여객선의 항해안정성을 평가하였다.
There are winds and waves in the sea, and they are changed frequently in accordance with the weather. By analyzing then which have the closest relation to the ship's safe voyage, evaluating the seakeeping performance and then taking a proper act on, navigators should carry out safe navigation on the sea A ship in seaways suffers continuous disturbances by irregular waves, and ship motions with irregular waves cannot be easily described as a system model which is adequate to a control system. But, in general, for seakeeping analysis, ship motions in irregular seas can be estimated by the superposition of the motion responses in regular wave components of the sea spectrum. After comparing and analyzing the winds and waves in major sea areas, this paper evaluates the navigational safety of ships on the Korean coast with potential dangerous seakeeping performance using the weather information provided by land The conclusion is as follows: (1) It is possible that the safety of ships could be secured more accurately by evaluating the seakeeping performance of ships. (2) When the weather is bad, the departure of ships could be controlled by evaluating the navigational safety of ships. (3) When a ship is placed in commission in any area, this evaluation could be used to decide the type and size of ship in use.
