SOLAS 2020对客滚船设计的影响

Influence of SOLAS 2020 on the Design of Ro-Pax Ships

新修订的SOLAS 2020规范与以往的规范相比,对包括客滚船在内的客船的破舱稳性有更高的要求。通过测算得知,现有的客滚船设计方案大多数不能满足新的分舱指数要求,需对其进行优化和升级。针对3种客滚船样本船型,提出提高初始工况初稳性高度、提高风雨密开口高度、增加型深、增加水密分舱和增加船宽等5种解决方案。通过评估这些方案在改善船舶破舱稳性方面的表现及其对船舶设计和营运的综合影响,给出满足新规范要求的思路和方法,为相关从业人员提供有益的参考。

Compared with the previous version,the newly modified SOLAS 2020 regulation stipulates higher requirements on the damage stability of passenger ships including Ro-Pax ships.Calculation shows that most of the existing Ro-Pax ship designs cannot comply with the requirements,so they are in demand of optimization and upgrading.This paper puts forward five technical solutions based on three sample Ro-Pax ships,i.e.increasing the value of initial metacentric height,increasing the height of weather-tight openings,increasing molded depth,increasing the number of subdivisions and increasing the width of the beam.Evaluation of the performance of these schemes in improving ship’s damage stability and their comprehensive influence on ship design and operation leads to some useful comments and methods to comply with the new regulation,which could be reference for relevant practitioners.
