This study aims at improving the channel of Pudo-sudo in Chinhae-Man according to the development project of the port of Masan, by investigating the design criteria of harbour facilities for the maximum sized ship. The new deep-water route was proposed and according to it the present separation scheme was adjusted appropriately. The width of the deep-water route is suggested to be 350m and would be wide enough for the 30,000 DWT container ship to go through However, the proposed channel will be tested and validated by the shiphandling simulator.
This study aims at examining the safety of the would-be approach channel of LNG Terminal at Kwangyang Harbour, by utilizing Captains 2000 port-design simulator. Six competent shipmasters or navigators participated in this study. The developed model ship was a 70,200DWT (138,000m3) LNG carrier. The environmental conditions were maximum flood-and-ebb current condition and wind condition. To evaluate the navigational safety, two categories were analyzed, which were measures of vessel's proximity and shiphandler's subjective evaluations. With respect to the effects of the worst environmental conditions on transit safety, it was concluded that the would-be approach channel was safe on basis of the support of four tugs of 3,200hp or more and current speed of 0.5knots or less.
The assesment of the safety of ship's transit in a curved narrow channl consists of the maneuvering safety determined by the chance of running aground, the maneuvering difficulty determined by shop's workload, and shiphandler's subjective evaluation. In this study to examine the correlation between shiphandler's subjectice evaluation and the maneuvering risk, the real-time and full-mission shiphandling simulator in the Korean Marine Training & Research Institutes(KMTRI) was utilized. In the conning bridge of the shiphandling simulator, 50 experienced masters conducted masters conducted the modeled vessel of 60,000 deadweight tonnage along the designed channel under 3 different envrinmental conditions. The findings were as follows: (1) The frequencies of stress levels, work difficulties, vessel controllability and overall workload of shiphandlers are similar irrespective of environmental conditions and they are able to be represented as shiphandler's subjective evaluation. (2) It is possible to assess and analyze theoretically the correlation between the shiphandler's subjective ecaluation and maneuvering risk each environmental cindition by quantifying the data obtioned from the tests. The results are as follows: ① As the degree of maneuvering risk increases, the shiphandler's subjective evaluation increases sharply near the curvature area of the desgined channel. ② In the area of the curvature of the designed channel, maneuvering risk increases sharply with the danger of running aground under the environmental condition of current and wind comung from the stem.

근래 세계 각국에서는 기존의 항로표지와 선박자동식별장치(AIS)를 혼합한 형태의 항로표지용 AIS를 도입하여 해상 상태 및 위치 등의 정보를 수집 전달하는 방식의 시스템을 구축하고 있다. 우리나라 역시 국제 동향에 맞춰 항로표지용 AIS를 채택하여 활성화시키는 단계에 있다. 그 중 서해안은 해양교통 환경이 매우 빠르게 변화하고 있는 곳으로, 현재 인천 및 대산 해역에 항로표지용 AIS 시스템을 설치하여 운영하고 있다. 이 연구에서는 항로표지용 AIS 시스템의 국내 표준을 구축하기 위한 목적으로 현재 항로표지용 AIS 시스템을 운영 중인 두 해역의 운영 실태를 분석하고 그 개선안을 마련하고자 한다. 이를 위하여 국제 항로표지용 AIS 관련 규정 및 국외의 항로표지용 AIS 시스템 구축 사례를 조사하고 관리조직모듈, 구성모듈, 정보모듈, 기능모듈 및 협력모듈의 5가지 모듈을 나누어 두 해역의 운영 실태 분석 및 개선안을 제시한다. 그 개선안은 시스템 관리 구조 불일치 개선, 다수의 항로표지용 AIS 정보표시로 인한 관리자 및 이용자의 정보 혼란 해소, 불필요한 정보 수신 문제 개선, 항로표지용 AIS의 수신불능 등 기능상 문제 개선, 항로표지용 AIS 정보의 비활용도에 대한 개선 등이다.
