基于SOLAS 2020概率破舱稳性要求的中型邮轮优化措施研究

The improvement measures of medium-sized cruise ships based on SOLAS 2020 probabilistic damaged stability requirements

  • 摘要:
      目的  破舱稳性是保障船舶稳性的重要性能之一,SOLAS 2020对客船分舱指数R的要求大幅提升,因此需要关注邮轮的概率破舱稳性。
      方法  以某中型邮轮为对象,对比分析SOLAS 2020和SOLAS 2009中所要求的分舱指数R;采用Maxsurf软件对初始方案进行概率破舱计算;通过对达到的分舱指数A的影响因素分析,提出沿纵向加密分舱、设置横贯进水装置、降低重心高这3种改进措施,并对改进方案进行分析。
      结果  结果表明,所达到的分舱指数 A 与SOLAS 2020中要求的 R 差距较大。与SOLAS 2009相比,SOLAS 2020对载客量约1 250人的某中型邮轮的R提升了约13.6%。设置横贯进水装置对A的改善效果达到10%以上,采用沿纵向加密分舱对 A 的的改善效果达到8.7%;由于初始GM值较大,采用降低重心高对A的改善效果较弱。而采用改进措施的组合方案,可使中型邮轮满足SOLAS 2020的分舱指数R的要求。
      结论  对于初始GM较大的中型邮轮,设置横贯进水装置的改善效果最佳,沿纵向加密分舱次之,降低重心高效果较弱。

     

    Abstract:
      Objectives  Probabilistic damaged stability is one of the most important factors to ensure the safety of ships. With the release of SOLAS 2020, the passenger ship subdivision index R requirement has been greatly increased. Therefore, attention should be paid to the probabilistic damaged stability of cruise ships.
      Methods  The R of SOLAS 2020 and SOLAS 2009 were compared and analyzed for medium cruise ships. The initial scheme was analyzed by using Maxsurf software. The difference between the R of SOLAS 2020 and the attained subdivision index A was large. Through analysis of the influencing factors of A, three kinds of improvement measures, including increasing the longitudinal subdivision, setting up cross-flooding fitting, and reducing the height of the center of gravity, were put forward. Also, the improvement schemes were analyzed.
      Results  Compared with SOLAS 2009, SOLAS 2020 has increased R of medium cruise ships carrying about 1 250 passengers by about 13.6%. The improvement of A is more than 10% by setting up cross-flooding fitting, 8.7% by increasing longitudinal subdivision, and the improvement of A is weaker by reducing the height of the center of gravity because of the larger initial GM. By adopting the combination scheme of improvement measures, the medium cruise ship meets the requirement of subdivision index R of SOLAS 2020.
      Conclusions  Through comparison, aiming at the medium-sized cruise ship with large GM, the improvement effect of setting up cross-flooding fitting is seen to be the best, followed by increasing the longitudinal subdivision, and the effect of reducing the height of the center of gravity is weak.
