Abstract

AtoN is an acronym for aids to navigation that indicate the position or direction of navigable areas and obstructions. AtoN should be arranged in consideration of unfamiliar navigator's convenience when it is indicated as the limits of navigable areas. Several narrow channels exist on the SW coast of Korea owing to the geographical effect, and the lateral or cardinal marks by the IALA maritime buoyage system are arranged along the narrow channels. This is an actual case study that analyzed the AtoN's role for safety navigation after changes in the maritime traffic environment owing to aquarfarm's development on narrow channels in the Korean SW coast. The analysis results of 5 narrow channels indicated that certain marks did not function properly as lateral or cardinal marks owing to the aquarfarm's location on navigable areas. Therefore, the following were suggested to improve AtoN on narrow channels: changing the position of marks, installing aquafarm's marks, and expressing the aquafarm's position on the nautical chart.

항로표지는 항행하는 선박에 대하여 가항수역의 위치·방향 및 장애물의 위치 등을 알려주는 항행보조시설이다. 항로표지가 가항수역의 한계를 표시할 때에는 해당 수역을 처음 이용하는 항해자의 입장에서 편리하게 이용할 수 있도록 배치되어야 한다. 우리나라의 서남해안에는 지형적인 영향으로 많은 수의 좁은 수로가 형성되어 있으며, 좁은 수로를 따라 IALA 해상부표식에 따른 측방표지 및 방위표지 등이 배치되어 있다. 본 연구는 우리나라 서남해안 좁은 수로에 배치된 항로표지가 양식장 개발 등의 해상교통 환경 변화 이후, 선박운항 안전에 대한 역할을 제대로 수행하고 있는지 검토한 실증 사례 연구이다. 서남해안의 5가지 좁은 수로에 대한 사례 검토 결과, 항로표지가 표시하는 가항수역 상에 양식장이 분포하여 항로표지로서의 역할을 제대로 수행하지 못하는 것으로 나타났다. 본 연구의 결과로, 해당 항로표지의 종별 혹은 위치 변경, 양식장 표지의 설치, 해도상 양식장 위치 표기 등의 개선방안을 제시하였다.
