초록

본 연구는 현재 감천항에 입항하는 선박교통 특성을 반영하여 감천항 도등의 효용성을 검토하였다. 감천항 도등은 1996년 4,000TEU 컨테이너선 출입항을 위해 감천항 항로표지 보완 기본설계과정에서 제안되어 설치되었다. 이후 부산지방해양수산청의 감천항 정온도 향상을 위한 기존 외곽 시설 재배치 검토 연구를 통해 50,000DWT급 일반 화물선 입항 대응 및 한진 부두의 크레인 높이를 반영한 도등으로 개선되었다. 그러나 현재 감천항의 해상교통 특성을 보면 해상교통 혼잡도도 원활하고 대형선박 보다는 10,000톤 이하의 중소형 선박 비중이 높아 대형선박 입항을 대응하기 위해 개선된 도등의 효율성은 감소되었다고 볼 수 있다. 그러나 입항선박의 규모에 따른 변화 추이를 보면 30,000톤 이상선박의 입항비율의 연평균증가율(CAGR)이 8.45%로 증가되고 있어 향후 대형선박의 입항비중 증가에 대한 대비를 위해서는 감천항 도등을 필수 등화로 유지하는 것이 필요하다. 따라서 도등을 철거할 경우 감천항 항로의 협소한 공간 특성상 입출항 선박이 조우하는 경우에는 충돌의 위험이 증가하여 항해자에게 큰 부담이 될 수 있기 때문에 도등의 기능은 유지하는 대신 전도등을 이전설치 하여 유지보수에 대한 부담을 경감시키는 방법과 도등의 기능 대신 지향등을 설치하는 방법을 고려해 볼 수 있다. 지향등 설치 시 인근 부산북항에 설치된 Single Sector Lights가 명확한 중시선을 제공하지 못하여 지점에 따라 명확한 구분이 어려움에 따라 이용자 만족도가 떨어지는 부분을 개선할 수 있는 Double Sector Lights를 설치를 고려해볼 수 있다.

This study examines the effectiveness of Gamcheon Port's leading lights in reflecting the characteristics of ship traffic entering the port. The leading light of Gamcheon Port was proposed and installed in 1996 during the basic design process of supplementing the port's route signs for the entry and exit of 4,000 TEU container ships. Since then, it has been improved to accommodate the entry of 50,000 DWT general cargo ships and to reflect the crane height of Hanjin Pier, as a result of a review study conducted by the Busan Regional Maritime Affairs and Fisheries Administration to improve the still temperature of Gamcheon Port by relocating existing outer facilities. However, an analysis of the current characteristics of maritime traffic at Gamcheon Port reveals that maritime traffic congestion is smooth and the proportion of small and medium-sized ships under 10,000 tons is higher than that of large ships, resulting in decreased efficiency of the leading lights to respond to the entry of large ships. Nevertheless, considering the increasing CAGR of the entry ratio of ships of 30,000 tons or more by 8.45%, preparations for the anticipated increase in the proportion of large ships entering the port in the future are necessary, and it is preferable to maintain the function of the leading lights rather than demolishing the entrance to Gamcheon Port. The narrow nature of the Gamcheon Port route poses a higher risk of collision when ships entering and exiting encounter each other, which can burden the navigator. Therefore, instead of maintaining the function of the leading lights, it is possible to relocate the conduction light to reduce maintenance burden and install a direction light in its place. When installing the direction light, it is worth considering using Double Sector Lights instead of the currently installed Single Sector Lights at nearby Busan Bukhang Port, as the former can improve user satisfaction by providing a clearer middle line and reducing difficulties in distinguishing between points.
