우리나라 연안 해역은 빈번한 선박조우로 인하여 해양사고 발생 잠재 위험이 높은 해역으로 분류되고 있으나 해상교통의 정량적인 평가의 미흡으로 맞춤형 안전대책이 제대로 수립되고 있지 않는 것이 현실이다. 본 연구에서는 해상교통 안전성 평가모델 중 하나인 IWRAP(IALA Waterway Risk Assessment Program)에 대한 기본적인 소개와 함께, 울산항을 대상으로 한 평가 사례 소개, 기존 유사한 연구와의 비교를 하고자 한다.

The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures have been developed, applied to the industries. In order to improve the navigational safety level in the coastal waterways, the navigational safety level must be evaluated from the mariner's perception of safety. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy measure and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VTS and navigational aids. The results are found in the order named Mokpo, Yosu, Pohang, Inchon, Busan, Geoje, Gunsan, Donghae coastal area.

The prevention of marine accidents has been a major topic in marine society and various polides and countermeasures rave been developed, applied to the industries. 1he coastal VIS and navigational aids are considered as one of the effective methods to promote marine safety but they need relatively huge amount of budgets to build Thus prior to establishing these coastal VIS and navigational aids, it should be evaluated the navigational safety level in the coastal waterways from the Environmental Stress. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process.

등부표는 선박이 운항할 때 경제적이고 안전한 항로를 선택할 수 있도록 유도하는 항행 원조 시설로 안전 항해에 매우 중요한 요소이다. 그러나 통항 선박의 추돌사고로 인하여 등부표의 파손 및 유실이 발생하고 있다. 따라서 본 연구에서는 해상교통평가모델을 활용하여 등부표 접촉사고 발생 위험성을 평가하고자 한다. 먼저 항만물동량이 높고, 항로에 등부표가 다수 설치된 부산항을 대상항만으로 선정하고, 부산항의 등부표 접촉사고 현황에 대하여 조사 분석했다. 그리고 부산항의 해상교통량을 기반으로 해상교통평가모델인 IWRAP, PARK Model을 활용하여 등부표 접촉사고 발생의 위험성을 평가했다. 추후에 다양한 해역의 접촉사고 위험성을 평가하고, 미래교통량을 추정 적용하여 등부표 신설 시 안전한 등부표 설치 해역 선정의 기초자료로 활용할 수 있을 것이다.

The coastal VTS and navigational aids are considered a, one of the effective methods to promote marine safety but they need relatively huge amount of budgets to build. Thus prior to establishing these coastal VTS and navigational aids, it should be evaluated the navigational risk level in the coastal waterways from the Environmental Stress.

In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy logic and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VTS and navigational aids.

Buoys are a necessary component for the safety of vessel traffic. However, if the buoy becomes inoperable from damage and loss, it can have significant impact on vessel traffic safety as well as unexpected budget spending. The purpose of this study was to evaluate the risk of accidental contact by applying the marine traffic assessment index that can reflect the traffic flow in the sea area. First, Busan Port No. 5 fairway, with a high number of buoys and many contact accidents, was set as the sea area for assessment. to investigate the status of accidental contact and evaluate risk of contact accidents based on the IALA Waterway Risk Assessment Programme (IWRAP MkII) and Potential Assessment of Risk Model (PARK Model). As a result, buoys are near the P recautionary Area wherein the traffic flow was complicated by the Masan port vessel and Busan new port vessel, and buoys are near the entrance of the Gadeok waterway, wherein vessels show a pattern of navigation across the fairway and buoys are near the breakwater in the inner fairway were considered as high risk for contact accidents. This study can be used as basic data for establishing an integrated model to evaluate the risk of buoy contact accidents.

해상에서 선박의 충돌확률을 평가하는 것은 해당해역의 잠재적인 해상교통 위험성을 평가하는데 있어 중요하다. 서남해권 해상교통에 중요한 요충지인 완도해역은 동서방향으로는 횡간수도 통과선박들이 항해를 하며, 남북방향으로는 완도항 입출항 선박과 다도해 섬들을 입출항하는 여객선들이 통항을 이루고 있다. IALA 정량적인 해상안전 평가방법인 IWRAP은 통항량, 선속, 길이, 선박의 통항분포로부터 해상에서 통항의 위험도를 평가하므로 인적, 지리적, 환경적 등 주관적인 요소들이 많은 정성적인 평가방법에 비해 적용이 간단하다. 본 연구에서는 VTS 섹터 관제의 관점에서 항로구간별 해상교통의 특징과 개선책을 세우기 위해 IWRAP을 활용하여 완도 해역의 충돌확률을 산출하고자 한다.
