Abstract

In ports of Korea, the marine traffic flow is congested due to a large number of vessels coming in and going out. In order to improve the safety and efficiency of these vessels, South Korea is operating with a Vessel Traffic Service System, which is monitoring its waters for 24 hours. However despite these efforts of the VTS (Vessel Traffic Service) officers, collisions are occurring continuously, the risk situation is analyzed that occurs once in about 20 minutes, the risk may be greater. It investigated to reduce these accidents by providing a safety standard for collision danger in a timely manner. Thus, this study has developed a risk prediction module to predict risk in advance. This module can avoid collision risk to adjust the speed and course of ship using a risk evaluation model based on ship operator's risk perspective. Using this module, the ship operators and VTS officers can easily be identified risks in complex traffic situations, so they can take an appropriate action against danger in near future including course and speed change. To verify the effectiveness of this module, this paper predicted the risk of each encounter situation and confirmed to be capable of identifying a risk changes in specific course and speed changes at Busan coastal water.

우리나라 항구 주변에는 입 출항하는 선박으로 인하여 해상교통흐름이 복잡하다. 이러한 선박통항의 안전과 효율성을 증진하기 위해 우리나라에서는 해상교통관제 서비스를 시행하고 있다. 24시간 쉴 틈이 없는 해상교통 관제사들의 노력에도 불구하고 관제구역 내에서의 충돌사고는 지속적으로 발생하고 있으며, 위험 상황이 약 20분에 1회씩 발생하고 있는 것으로 분석되어 그 위험성은 크다고 할 수 있다. 이러한 사고는 선박운항 및 해상교통관제 정보 제공 시 충돌 위험에 대한 안전 기준을 적시에 제공함으로써 사고를 감소시킬 수 있을 것으로 조사되었다. 이에 본 연구는 선박의 충돌위험도를 선박운항자의 관점에서 평가할 수 있는 모델을 이용하여 그 위험을 선박의 속도, 침로 등을 조정하여 각 교통 상황별 충돌 위험도를 사전에 예측 할 수 있는 위험도 예측 모듈을 개발하였다. 이 모듈을 이용하여 선박운항자 및 관제사는 복잡한 교통 상황에서 위험요소를 쉽게 식별 할 수 있어, 가까운 장래의 위험 정도의 변화를 선박침로 및 속력변경 등을 제시할 수 있는 등의 적절한 피항조치를 취할 수 있다. 이 모듈의 효용성을 검증하기 위해 부산항 해역을 대상으로 조우 상황별 위험도를 예측 후 구체적인 침로 및 속력 변경에 따른 위험도 변화를 식별할 수 있는 것으로 확인되었다.
