Abstract

The objective of this study was to analyze the risk of collision accidents to the VTSOs (Vessel Traffic Service Operators) as small ferries and fishing boats are expanded for monitoring targets. The VTSOs was surveyed, the scale of the small vessels defined and the course of general cargo vessels and small vessels along the Busan VTS area investigated for three days. From calculating the risk with CoRI, patterns of increased or decreased risk due to course deviation were similar, and there was no significant difference between the maximum values and the minimum values. In addition, most VTSOs responded that the minimum time required was approximately three minutes to safely instruct in encounter situation, however, the collision risk with a small vessel is very rapidly changing within the three minutes, which is likely to increase the workload and decrease the concentration of the VTSOs. The objective of this study was to investigate the effect on VTSOs with respect to the expansion of small vessels as collision risk, it is expected that it will contribute to the establishment of a suitable scale for the target vessels for VTS through the analysis of each index of the CoRI model and various case studies.

본 연구는 유선, 어선 등이 관제대상으로 확대됨에 따라 해당 선박이 VTS(Vessel Traffic Service) 관제사에게 미치는 충돌사고 위험도를 분석하는 데 목적이 있다. 이를 위해 VTS 관제사를 대상으로 설문을 하고 소형선박의 범위를 정하여 부산 VTS 관제 구역을 항해하는 일반상선과 소형선박의 침로 등을 3일간 조사하였다. 이를 VTS 관제사 관점에서의 충돌위험 평가모델(CoRI)로 위험도를 구한 결과, 침로 편차에 따른 위험도의 증가 감소 패턴은 비슷하였고, 최댓값과 최솟값은 큰 차이가 없었다. 또한 대부분 VTS 관제사는 선박근접상황에 대해 안전하게 관제할 수 있는 최소 시간으로 3분이 필요하다 응답하였는데, 소형선박의 충돌위험도는 3분의 시간 동안 매우 급격하게 위험도 변화를 보여 VTS 관제사의 업무량 증가와 집중도 저하 우려가 있다고 판단된다. 본 연구는 소형선박의 관제대상 포함 여부가 VTS 관제사에게 미치는 영향을 충돌위험도로 검토한 것으로, 향후 다양한 사례를 통한 CoRI 모델의 각 지수에 대한 분석과 검증을 통해 관제 대상 선박의 적절한 범위 설정을 위한 방안 마련에 기여할 수 있을 것으로 기대된다.
