Abstract

ABSTRACT A new approach for analysing the level of survivability for a passenger ship in the event of a collision damage is presented. Monte Carlo simulation is used for generating a large number of damage cases. The probability distributions for damage extent and location are based on the current SOLAS regulation. Each case is calculated with time-domain flooding simulation, assuming quasi-static motions and calm sea, thus enabling evaluation of the righting lever curve during the flooding process. The ship survivability is analysed based on requirements for a sufficient reserve stability. The proposed method is demonstrated with a large passenger ship design. Based on the detailed investigation of the results, the effects of various design changes are studied. Furthermore, the impact of waves on the flooding process is studied. The presented method for survivability assessment is robust and especially suitable for comparing design variations, or ships with similar main dimensions.
基于仿真的客船损伤生存能力分析方法
摘要提出了一种分析客船在碰撞损伤情况下生存能力水平的新方法。蒙特卡罗模拟用于生成大量的损伤案例。损伤程度和位置的概率分布基于现行的SOLAS规则。假设准静态运动和平静的海面,通过时域洪水模拟计算每种情况,从而能够评估洪水过程中的扶正杠杆曲线。根据对足够的储备稳定性的要求,对船舶的生存能力进行了分析。该方法已通过大型客轮设计进行了验证。在对结果进行详细调查的基础上,研究了各种设计变更的影响。此外,还研究了波浪对淹没过程的影响。所提出的生存能力评估方法是稳健的,特别适用于比较设计变化或具有相似主要尺寸的船舶。
