Abstract

To prepare the integrated safety management system 'e-navigation', research is being conducted on the route exchange for sharing intended routes between ship and ship, and between ship and land. But they don't have enough specific grounds for the effects of route exchange and the necessity of its introduction and focus on technical aspects like the implementation of route exchange. This study tried to quantitatively analyze the effects of route exchange on sailing safety with the use of ship handling simulation, integrate simulation performers' subjective evaluations, and investigate the effects of route exchange. The ship-to-ship route exchange resulted in the initial collision avoidance action time was 3.43 minutes faster, the collision avoidance direction change rate was 60 %, the proximity to target A was 31 %, and Mean Rudder Angle Index decreased by 57 %. In addition, 95 % of the survey respondents had an effect on the decision making of collision avoidance, 85 % had a positive impact on safety navigation, 90 % had an accident prevention effect, 70 % reduced the psychological burden of officers, and 70 % should be introduced in practice.

종합 안전관리체계인 e-navigation을 준비하기 위해 선박의 의도된 경로를 선박 대 선박, 그리고 선박 대 육상 간에 공유하는 경로교환에 대한 연구가 활발히 진행 중이다. 하지만 경로교환을 위한 기술적인 측면에서의 연구 개발은 진행되고 있으나, 그 효과나 문제점 등 도입 필요성에 대한 연구는 부족한 실정이다. 본 연구는 선박조종 시뮬레이션을 통해 경로교환이 항해 안전에 미치는 영향을 정량적으로 분석하고, 시뮬레이션 수행자들의 주관적인 평가를 종합하여 경로교환의 효과를 검증하였다. 선박 간 경로교환을 할 경우 최초 충돌회피 시점은 평균 3.43분 더 빨라졌으며, 충돌회피 방향은 60 %가 변경되었다. 또한 타선 A와의 최근접점은 31 % 더 가까워지고, 평균 타 사용지수는 57 % 줄어들었다. 그리고 설문 응답자의 95 %는 경로교환이 충돌회피 의사결정에 영향, 85 %는 안전운항에 긍정적인 영향, 90 %는 사고예방 효과, 70 %는 항해사의 심리적 부담 경감, 70 %는 경로교환을 실무에 도입해야한다고 답하였다.
