초록

선박 운용에 있어 가장 어려운 과정 중의 하나가 접안작업이고, 따라서 도선사 및 예인선의 도움이 반드시 필요하다. 그 외 접안작업을 도울 수 있는 도구는 안벽에 설치된 고무형 펜더가 전부라 할 수 있다. 이러한 고무형 펜더의 한계를 극복하기 위해 짧은 범위에서 길이조정이 가능한 펜더기술이 개발되었으나 여전히 접안작업의 불편함은 크게 해소되지 못한 실정이다. 따라서 본 논문에서는, 접안작업의 안전성과 신속성을 개선할 수 있는 새로운 개념의 접안지원기술을 제안한다. 실린더형 펜더와 윈치시스템으로 구성하였으며, 펜더 스트로크 및 윈치-로우프의 장력조정으로 접안선박의 이동속도 및 안벽과의 거리제어가 가능하다. 또한 이동식으로 구성하여 선박의 접안위치에 따라 신속하게 대응할 수 있다. 개발한 시스템의 유용성을 평가하기 위해 실선을 대상으로 한 현장실험을 수행하였으며, 그 결과를 본 논문에서 소개한다.

Maneuvering vessels in the harbor is an interesting problem in marine cybernetics. The vessel, operated by the pilot and moving very slowly in shallow water, usually is assisted by thrusters, the main propulsion system, and tugboats. In this paper, we suggest a new vessel berthing technique using dampers (cylinder-type fenders) and a system of winches for complex and dangerous berthing situations. We found that control of the fender stroke and rope tension enabled a safe and quick berthing process. The effectiveness and usefulness of this berthing system was verified using a ship of about 2,000 tons.
