초대형컨테이너선의 양현하역(수치 및 실험결과)

Abstract

The feasibility of placing a large floating quay on the star-board side of a container ship for offloading from both sides is investigated. A 1:100-scale model test was conducted for the tree-body system in side-by-side arrangement including fixed land wall, a container ship, and a floating harbor with small gaps. The same system is also modeled by a 3D multi-body time-domain motion simulation program and the calculated relative motions and fender/mooring forces are compared against the model-test results. The numerically predicted RAOs, dolphin/fender forces, and motion time histories and their statistics reasonably correlate with those from experiment. The floating harbor system performs excellently for a typical operational condition, while they can exceed operational limits in the worst-possible wave condition. The developed computer program should be a useful numerical tool for the optimal design of future large-scale floating harbors.
