위험도 평가는 양적인 평가방법(정량적 평가방법)과 질적인 평가방법(정성적 평가방법)이 있다. 해상에서 정량적인 평가방법은 선박의 통항량, 통항분포, 속력, 길이, 침로, 흘수 및 해상의 수심 등의 기하학적인 자료를 토대로 위험도를 산출하는 방법이다. 본 연구에서는 VTS 통항데이터를 정량적인 평가툴인 IWRAP에 적용하여 목포항 진입수로의 속력별, 길이별 통항분포와 해상교통위험도를 평가분석 하고자 한다.

In this study, with the objects of 173 institutions of university and research institutions, investigation was carried out through visit investigation ar d questionnaire investigation. Frequency and severity of occurrences was acquired mainly through universities and research institutions which have reported occurrences of accidents to the Ministry of Education, Science, and Technology. Quantitative danger evaluation was conducted through frequency and strength of occurrences. Case study was carried out by selecting bio science laboratory of university and as the result of this study, degree of danger among the inspection objects of bio science laboratories, laboratory work place was evaluated as the most dangerous with the scores of 155.00 and as the result of average danger level, compression gas cylinder was evaluated as the most dangerous with the scores of 6.4000.

The quantitative evaluation method of the safety management cost was suggested to prevent a gas accident as a major industrial accident. In a gas governor station, process risk assessments such as the fault tree analysis(FTA) and the consequence analysis were performed. Based on process risk assessments, potential accident costs were estimated and the cost-benefit analysis(CBA) was performed. From the cost-benefit analysis for five classification items of safety management cost, the order of the cost/benefit ratio was estimated.
