Abstract

The Myodo-Strait at Yeosu Port is normally used as a major vessel passage for dangerous cargo carriers that carry regular products of dangerous goods. Currently, the Myodo-Strait allows only single passage, and the speed of passage is also limited to 8 knots. As a result, demurrage at the wharf of hazardous goods are also on the rise. It is expected that the development of a number of dangerous commodity wharf in the future will increase the volume of vessel traffic and increase the number of vessels used in the project area. Therefore, it is urgent to improve the waterway in order to secure the safety of ships using the waterway and improve the demurrage. This study proposed an improvement plan for the waterway through the analysis of the marine environment of the waterway and the process of collecting opinions from users in the sea area. and it was finally proposed to expend the width of the strait to 300m and secure a depth of 9.50m through Guidelines of Port and Harbor Design review and ship handling simulation evaluation. In addition it was evaluated that the vessel traffic congestions at peak-time in the situation of solo passage was greatly improved from 71.01% to 47.3% even when it was allowed to ship's crossing passage, as a result of vessel traffic congestions evaluation. According to the proposed improvement plan, the safety of ships' passage in the project area can be secured, and the issue of demurrage was also considered to be improved.

여수항 묘도수도는 위험물 정제품을 운반하는 위험화물운반선의 주요 선박통항로로 이용되고 있다. 현재 묘도수로에서는 단독통항만을 허용하고 있고 통항 속력 또한 8노트로 제한되어 있다. 이로 인하여 위험물 정제품 부두에서의 체선료 또한 증가 추세에 있다. 향후 다수의 위험물 정제품 부두의 개발로 인하여 대상해역의 이용선박은 더욱 대형화되고 선박통항량 또한 증가될 것으로 예상하고 있다. 따라서 묘도수로를 이용하는 선박의 안전성 확보 및 체선료 개선을 위해서 묘도수로의 개선이 시급한 시점이다. 본 연구에서는 묘도수로의 해상환경 분석 및 해역 이용자 의견수렴 과정을 통하여 묘도수로의 개선안을 제시하였으며, 항만설계기준 검토 및 선박조종 시뮬레이션 평가를 통하여 항로 폭을 300m로 확장하고 수심 9.50m로 확보하는 방안을 최종적으로 제시하였다. 또한 해상교통혼잡도 평가 결과 현재 단독통항만이 허용되고 있는 상황에서 피크타임 해상교통혼잡도는 71.01%에서 교행이 허용되는 상황에서도 47.3%로 크게 개선되는 것으로 평가되었다. 제시한 묘도수로 개선방안에 따라 대상해역에서의 선박 통항안전성을 확보할 수 있으며, 체선료 문제 또한 개선될 것으로 판단되었다.
