The introduction of the ‘Safe Return to Port’ (SRtP) regulations strongly impacted the design of passenger ships. To meet the functional requirements of these regulations, the systems on board reached an extreme level of complexity in terms of redundancy and segregation, considerably increasing the difficulties to assess the compliance of the designs. However, non-compliant designs are a major risk for every design company which must prevent at all costs the possibility of expensive re-designs in later stages of the process. The aim of this research is to address the gap in the literature and in the market of design support tools, presenting a method to effectively mitigate the risks of non-compliant solutions with SRtP. The method comprises a thorough analysis of the spaces on board and a software tool for the assessment of the correct placement of the systems components. The value of the solution proposed was assessed in two case studies in which the method has been proven capable of effectively identifying the non-compliant solutions in a convenient and time-saving manner. Additional features for the suggestion of solutions to achieve the compliance have been implemented in the tool to further support designers during the complex design process of SRtP projects.

“安全返港”(SRtP) 法规的引入对客船的设计产生了强烈影响。为了满足这些法规的功能要求，船上系统在冗余和隔离方面达到了极高的复杂程度，大大增加了评估设计合规性的难度。然而，不合规的设计对每个设计公司来说都是一个主要风险，他们必须不惜一切代价防止在流程的后期阶段进行昂贵的重新设计的可能性。本研究的目的是解决文献和设计支持工具市场中的差距，提出一种有效降低 SRtP 不合规解决方案风险的方法。该方法包括对船上空间的全面分析和用于评估系统组件正确放置的软件工具。所提出的解决方案的价值在两个案例研究中进行了评估，在这两个案例研究中，该方法已被证明能够以方便且省时的方式有效地识别不合规的解决方案。该工具还实现了为实现合规性而提供解决方案建议的附加功能，以在 SRtP 项目的复杂设计过程中进一步支持设计人员。
