황해형 하역시스템의 구조설계

초록

West coastal ports of Korea experiences severe tidal range with up to 9.7 meter between high and low tides. The significant water level variation implicates many operational difficulties during loading and un-loading from cargo ships. To overcome problems due to tide and to secure the continuous loading operation, a new loading system for container cargo called "container pallet system" is developed and introduced in the paper. Three types of structure forms, offshore structural deck, double bottom structural form and the mixed form, are investigate with MSC/NASTRAN software. The results prove that the mixed type structure with truss enforcedment is found to be the most appropriate for the region.
