제주신항의 해상교통안전성평가에 관한 연구

A Study on the Assessment of the Marine Traffic Safety through Construction of the Jeju New Harbor

80,000 G/T급 크루즈선이 입항할 수 있는 터미널을 계획하고 있는 제주신항에 대하여 자연ㆍ환경 조건 및 방파제 등의 구조물 등을 고려하여 선박조종시뮬레이션을 실시하여 입ㆍ출항 및 접ㆍ이안의 안전성을 평가하고자 한다. 안전성 평가는 항로경계의 침범여부, 구조물과의 최근접거리, 선박조종자의 주관적 평가를 통계적으로 해석하는 방법을 이용하였다.

In accordance with the development plans of Jeju for international free city, Jeju new harbor will be constructed cosidering supporting Jeju city as an international tour city, safe arrival and departure at the terminal of 80,000G/T cruise ship. In this study, we used a lull-mission ship handling simulator adopting 80,000 G/T cruise ship manoeuvered at the planned Jeju international cruise terminal. Five masters who have had a long experience of ship maneuvering were called to carry out the simulations, of which No. 1, No. 2 and No. 4 scenario of simulation were tried twice, completed the total of 10 times and No. 3 scenario of simulation once, reached at the total of 5 times. The marine traffic safety was assessed in terms of 1) the closest point of approach(CPA) to breakwater and quay in the vicinity and the probability of crossing fairway limit, 2) subjective evaluation such as the mental burden and the maneuvering disfficulty of shiphanders, and 3) the opinions of shiphandlers. From the result of this simulation, we have a conclusion that the 80,000 G/T cruise ship can be maneuvered safely at the planned terminal.
