Abstract

최근 해상교통 안전성 평가의 주요 기법으로 부각되고 있는 “환경 스트레스 모델”을 구성하는 두 요소 중, 본선 주변의 지형적인 제약에 기인하는 조선 환경 스트레스 모델의 개념과 특성에 대해 살펴보고, 이러한 기법을 항만이나 항로의 설계시 그 안전성 평가에 어떻게 활용할 수 있는가에 대하여 고찰해 보았다. 본 모델을, 가상적인 몇 가지 경우에 적용함으로써 그 개념과 특성을 보다 명확하게 고찰하고자 하였으며, 또한 부산항, 광양항 등 우리나라 주요 항만의 실제 접근 항로에 적용하여 보았다. 본 기법은, 항만이나 항로의 설계 및 그 안전성 평가에 큰 도움이 될 수 있을 것으로 판단된다. The concept of “Environmental Stress(ES)” can be used as a useful index when assessing the maritime traffic safety. It is composed of two parts, one due to geographical restriction and another one due to traffic congestion. In this paper, Environmental Stress due to geographical restriction is reviewed Its characteristics are surveyed from the sample calculation results for some hypothetical cases, such as approaching a breakwater, navigating in a long straight channel, and in a long bended channel. Sample calculations are also carried out for the approach channels in Busan and Kwangyang harbor. By using this ES concept, it is expected that objective ana quantitative assessment of safety is possible for various environmental conditions when navigating in a harbor or in a fairway.
