초록
제주 연안은 국제크루즈선, 여객선, 유‧도선 등의 통항이 빈번하고 조업 어선이 많아 해양사고 위험성이 높고 선박 충돌사고가 빈번히 발생하고 있다. 이에 따라 제주 연안 해역을 통항하는 선박의 체계적인 안전관리를 위해 연안 VTS 구축이 시급하다. 본 연구의 목적은 신설될 제주지역 연안 VTS의 관제구역을 설정하고자 한다. 관제사의 업무부하를 측정하기 위해 관제대상 선박과 비관제대상 선박에 대한 모니터링 빈도 및 소요시간 등을 고려한 모니터링 업무량과 선박충돌 조우상황 등에 대한 관제업무량을 반영한 산정식을 설계하여 신설될 제주지역 VTS의 각 관제섹터에 적용하였다. 각 VTS 센터에 3개의 관제섹터를 설정하였으며, AIS 데이터 한 달 치를 이용하여 시간당 평균 관제석을 분석한 결과, 1석 내외로 나타나 섹터간 구획 획정은 적절하여 관제사의 업무부하는 없는 것으로 나타났다. 본 연구에서 제안한 방법은 현재 운영 중인 VTS의 적정 관제석 산출 및 향후 신설될 연안 VTS의 관제구역 설정 등에 기초자료로 활용할 수 있을 것으로 기대된다.
Abstract
On the Jeju coast, international cruise ships, passenger ships, and other ships pass frequently, as well as many fishing boats. Thus, there is a high risk of marine accidents and frequent ship collisions. Accordingly, it is urgent to establish a coastal VTS for systematic safety management of ships passing through the coastal waters of Jeju. The purpose of this study was to set the area of the VTS to be newly established. In this study, to calculate the workload of the VTS operators, a formula was proposed that reflects the monitoring workload considering the monitoring frequency and required time for target as well as non-target ships and the workload for ship collision situations. The proposed formula was applied to the newly established VTS area in Jeju. Three control sectors were set up in each VTS center. The average number of workstations per hour was approximately 1, so the division between sectors was appropriate. Thus, it was deduced that there would be no workload for the VTS operators. It is expected that the method proposed in this study can be used as primary data for calculating the appropriate number of workstations for the current VTS, and setting the VTS area for a new coastal VTS in the future.
