Abstract

Ships encounter other vessels during navigation and must respond accordingly based on established regulations. However, these regulations offer only broad principles without specific guidelines. Therefore, ships rely on the judgment of the ship operator under these broad principles. The ship operator provides responses based on the type of vessel they are operating, which can result in different perceived safe distances between merchant and small-vessel operators. This study analyzes the differences in crossing-distance perceptions between these two groups. A marine traffic survey and questionnaire are conducted. The results show that vessels in the Gaduk Strait maintained a crossing distance of approximately 300 m. The survey indicates that small-vessel operators perceive a shorter safe distance than the risk distance recognized by merchant-vessel operators. This highlights the necessity for different appropriate distances depending on vessel size and confirms that a consistent separation distance is necessary regardless of the vessel length.

선박은 운항 중 다른 선박과 조우하며, 정해진 규정에 따라 대응해야 한다. 그러나 이러한 기준은 큰 원칙만 있을 뿐 구체적인 수치는 제시하지 않고 있다. 그러므로 큰 원칙에 따라 선박운항자의 판단에 따라 선박은 대응한다. 선박운항자는 자신이 승선한 선박의 상황에 맞춰 대응하기 때문에 일반 상선운항자와 소형선박운항자의 이격거리에 대한 인식은 다를 수가 있다. 본 연구는 일반 상선운항자와 소형선박 운항자의 횡단 관계 시 이격거리에 대한 인식차이를 분석하고자 했다. 이를 위해 해상교통조사를 수행하고 선박운항자 대상 설문조사를 수행했다. 해상교통조사 결과, 가덕수도를 통항하는 선박은 선수방향에 약 300m의 이격거리를 통항하고 있었으며, 설문조사 결과 소형선박운항자의 안전거리가 일반 상선운항자의 위험거리보다 짧은 것으로 나타났다. 이를 통해 선박크기별로 적정 이격거리는 차이가 있어야 하며, 선박 길이와 관계없이 타선박과 일정한 이격거리가 필요함을 확인했다.
