ABSTRACT

SOLAS2020 damage stability regulations are based on probabilistic damage distributions. Those originate from the pooled analysis of collision accidents across a fleet with bias towards cargo ships. This paper introduces a method that accounts for collision-based crashworthiness on ship damage distributions. The method reshapes statistical SOLAS damage distributions for a given ship or structural details for a reference ship section and her reinforced version. Damage reductions may differ depending on ship characteristics and operational scenarios. To mitigate this, a high number of collision scenarios was simulated using the super-element method. It is shown that risk control in terms of damage reduction over the whole range of damages is possible by adding a double hull or by deck reinforcement. Damage reduction is quantified by damage stability analysis of a cruise vessel. It is concluded that installing a double hull on ship vulnerable zones leads to increased A-index.

摘要

SOLAS2020 损伤稳定性规定基于概率损伤分布。这些源于对偏向货船的船队碰撞事故的汇总分析。本文介绍了一种计算基于碰撞的船舶损坏分布的耐撞性的方法。该方法重塑了给定船舶的统计 SOLAS 损伤分布或参考船截面及其加固版本的结构细节。减损可能因船舶特性和操作场景而异。为了缓解这种情况，使用超元素方法模拟了大量的碰撞场景。结果表明，通过添加双壳或甲板加固，可以在整个损坏范围内减少损坏方面的风险控制。损伤减少通过游轮的损伤稳定性分析来量化。得出的结论是，在船舶脆弱区域安装双壳会导致 A 指数增加。
