摘　　要：敞口集装箱船是一种出于经济性目的,而允许不设置舱口盖的特殊集装箱船型。由于其特殊性,甲板上浪导致的货舱进水/积水对于船舶稳性会产生十分不利的影响。为了确保此类船舶具备充足的稳性裕度并减小甲板上浪,科学合理地核定干舷对于确保安全具有十分重要的意义。目前国际公约和各国法规均对常规船舶最小干舷高度给出了明确的要求,相关计算公式主要基于长期的船舶建造、使用经验或有限的样船模型试验样本结果得到。出于船型特殊性考虑,则允许敞口集装箱船通过开展甲板上浪试验的方式核定干舷。论文采用模型试验方法,分析了开展甲板上浪模型试验时合理确定波浪中航速的数值计算方法,对比研究了不同试验方法对于上浪进水量的影响,给出了完善敞口集装箱船干舷核定的甲板上浪评估方法的建议。Open-top containership is a special type of containerships without hatch covers for economic purpose,but accumulated water in open cargo holds caused by shipping water will have an adverse effect on intact stability.International conventions and national laws have given clear requirements for the minimum freeboard for conventional ships.Considering the particularity of open-top containership,it is allowed to determine its freeboard through shipping water model test.In this paper,calculation method of determining ship speed in waves is analyzed based on model test.Influence of different test methods on accumulated water in cargo holds are studied through model tests.Suggestions for improving assessment of shipping water are provided to determine freeboard of open-top containerships.
