4차 산업혁명시대에 해운산업에서는 자율운항 선박의 출현이 예상되고 있다. 이와 관련된 충돌회피 시스템 연구는 활발하지만 대부분 상선을 중심으로 추진되고 있다. 자율운항 선박이 조우하게 될 모든 선박을 고려하였을 때 어선과의 충돌회피 시스템 연구 또한 반드시 필요하다. 본 연구에서는 어선의 점용면적(Ship's domain) 반영한 충돌회피 모델의 연구를 위하여 부산항과 인근 해역의 중·소형 어선과 모든 선박과의 통항 이격거리를 조사하였다. 통항량이 가장 많은 기간의 AIS 데이터 중에서 조우관계에 있는 어선과 모든 선박간 상대위치를 원형산포도로 나타내었고, 이를 대상선박으로부터 방위별 평균 이격거리 및 최다 통항 이격거리로 분석하였다. 분석 결과, 어선의 속력이 증가할수록 평균 이격거리는 방위별 4L에서 8L 정도로 증가하였고, 선박 길이가 증가할수록 10L 이상이던 평균 이격거리가 약 6L 정도로 감소하는 경향이 나타났다. 추후 어선의 점용면적 일반화를 통한 충돌회피 모델에 연구에 본 기초결과가 활용될 수 있을 것으로 기대된다.

In the era of the fourth industrial revolution, Maritime Autonomous Surface Ship(MASS) are expected to emerge in the shipping industry. There has been much active research on collision avoidance systems regarding MASSs, but most of it has focused on merchant ships. A study of collision avoidance systems in fishing vessels is also essential, because Maritime Autonomous Surface Ships will encounter all type of vessels. In this study, the minimum passage distance between small-medium-sized fishing vessels and other vessels was investigated for the Ship's domain analysis. Based on the AIS data of Busan port and the adjacent area, the separation distances of fishing vessels were analyzed. The results indicated that as the speed of fishing vessels increased, the distance increased from 4L to 8L, and as length of the fishing vessels increased, the distance decreased from 10L to 6L. It is believed that the results of this study can be applied in the future to collision avoidance models for MASSs that reflect the domain of fishing vessels.
