驳船的影响概率破舱稳性单因素研究

概率破舱稳性是干货船破舱稳性计算与校核的一项强制性要求,它不同于传统的破舱稳性计算,计算中涉及到大量的破损舱室的组合,目前仍然是在分舱之后才能进行分析计算,若不满足则需要返回重新分舱。在初步设计阶段,如何有效分舱以使船舶分舱设计能满足概率破舱稳性,以减少分舱的盲目性与重复性,从而找到基于概率破舱稳性的分舱指导原则,这将具有重要的理论意义和工程应用价值。以某实际工程驳船为研究对象,设计了大量的分舱方案,并分别对其进行概率破舱稳性计算。根据计算结果对影响分舱指数A的因素进行了定性分析,提出了改进分舱指数A的设计准则。

Study on Influence Factors of Ship Probability Damage Stability

Since determinate damage stability calculation method has lots of deficiency,probability damage stability has been brought about and become a compulsory calculation for dry cargo ships.In order to perform probability damage stability calculation,a large number of damaged compartment combinations have to be calculated that is time-consumable.If the obtained index A is less than demanded index R,subdivision has to be done once again until A is larger than or equal to R.How to compartmentalize reasonably is a crucial problem.This paper takes a barge for example ship and designs lots different compartment arrangements.Probability damage stability calculations for different arrangements are carried out respectively.Based on the calculation results,some qualitative principles to guide subdivision are presented,which can provide a practical tool for engineering application and improve arrangement design quality.
