Abstract

Mobile Harbor(MH) is a new paradigm for maritime transport system introduced in Korea, the target of which is to carry out ship-to-ship cargo operation rapidly and effectively even under a condition of sea state 3. A MH ship is moored alongside a large container vessel anchored at the defined anchorage and also equipped with gantry cranes for handling containers. The MH study concerned includes rapid container handling system, optimum design for floating structure, hybrid berthing & cargo operation system, design for cargo handling crane, etc. This paper is to deal with a conceptual design of a stabilized mooring system and mooring equipment under a condition of ship-to-ship mooring. In this connection, we suggest a positioning control winch system in order to control heave motions of the MH ship which is to add constant brakepower and stabilized function to an auto-tension winch and mooring equipment used currently in large container ships.

하역장치가 장착된 모바일하버 선박은 새로운 해상운송시스템 개념으로, 특정 정박지에서 대형 컨테이너 선박에 계류하여 해상상태 3 이하 조건에서 신속하면서 효율적인 컨테이너 하역작업을 수행하는 것이다. 모바일하버와 관련한 주요 연구로는 고속하역시스템, 부유체 구조 설계, 안벽하역시스템 해석 및 작업크레인 설계 등의 원천기술 개발을 중심으로 수행되었다. 본 연구는 모바일하버 선박의 하역작업 중 동적안정성 확보를 위한 계류안정화시스템을 개발하고자 하는 것으로, 국내외 계류장치에 대한 현황 분석을 기초로 현재 선박에 탑재되어 있는 의장장치인 윈치시스템에 계류안정화 기능을 추가시킨 포지셔닝윈치를 개발하여 모선과의 상대운동을 최소화하는 방안에 대한 개념설계를 제안한다.
