VTSO(Vessel Traffic Service Operator)는 양 선박의 충돌위험 정도를 판단할 때, 선박들의 침로와 속력, DCPA(Distance to CPA)와 TCPA(Time to CPA) 그리고 양 선박의 조우상황 등을 종합적으로 고려한다. 이에 본 연구에서는 VTS관점에서 선박충돌 위험도를 구하기 위하여 CPA에서의 양 선박 상대방위에 따른 조우상황 위험도와 선박의 길이를 고려한 양 선박의 범퍼영역에 대한 근접 위험도를 이용하여 두 선박의 다양한 교차상황에 따른 선박 충돌위험 값을 비교하였다.

정박중인 선박의 안전을 위하여 항해사 및 선장, 해상교통관제사(VTSO, Vessel Traffic Service Operator)는 수시로 선박이 주묘가 되는지 확인하여야 한다. 일반적으로 정박선의 주묘여부 판별은 선위측정에 의한 방법과 선체움직임을 감지하여 확인하는 방법이 있다. 하지만 VTSO는 실제 선박의 구체적인 정박상황 파악이 어려우므로 수신되는 위치정보를 바탕으로 주묘여부를 판별해야 한다. 본 연구는 VTS에서 AIS에 의해 수집되는 데이터를 활용하여 VTSO의 경험적 주묘여부 판별 알고리즘을 토대로 VTS에서 활용가능한 정박선 주묘판별 프로그램을 제시하고자 한다. 또한 구성된 프로그램을 완도주변해역에 적용하여 선박주묘여부를 판별하였다.

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.

In Gwangyang port, huge reclaiming work and developing harbor facilities are underway to built industrial complexes. So it is estimated that towing barges will increase and make overtaking, head-on, crossing situations with a lot of cargo vessels in narrow passages. And it is possible to cause severe marine accidents inside of the harbor. This paper has a purpose to produce some policies making navigational safety of towing-barge on Gwangyang Hysco temporary passage. So it is considered how the change of marine traffic capacity and the risk factors in passage navigation influence to towing-barge navigation. And also the questionnaire survey of pilots and VTS operator was conducted to find out what they think about the navigational safety of towing-barge incoming and outgoing in No.1 Yulchon industrial complexes.
