事故下保障极地小型邮轮安全的电气系统设计

Design of electrical system to guarantee safety of small polar cruise ship after casualty

  • 摘要:
      目的  为了解决极地航线所特有的天气状况恶劣、航线偏远、救援时间长、无合适的救援补给停靠港口等不利于保障人员安全的问题,提出在发生火灾或进水事故时,将极地邮轮本身视为救生艇的设计理念,深入探讨实现该理念的电气系统设计方法。
      方法  通过对极地航线环境特点的分析,总结极地航行风险及应对措施,结合“安全返港”理念,提出邮轮动力及人员安全的重要电气系统功能目标。总结双套冗余电气系统设计通用拓扑结构,结合应实现的设计目标和原则对典型电气系统的设计方案展开分析。
      结果  结果显示,在设计建造小型邮轮时尽可能采用双套冗余或隔离设计原则,可实现重要电气系统在发生事故后仍能维持运行这一设计目标,能极大地提高邮轮上人员的生命安全保障能力。
      结论  所做研究可为极地小型邮轮的电气系统设计提供思路和参考。

     

    Abstract:
      Objectives  In order to solve problems such as bad weather conditions, remote routes, long rescue time and no suitable port of call for rescue supplies, which are unique to polar routes and not conducive to personnel safety, this paper presents a design concept in which the polar cruise ship itself is the best lifeboat in the event of fire or flooding, and discusses an electrical system design method for realizing this concept.
      Methods  This paper analyzes the characteristics of the polar route environment, summarizes risks and countermeasures, combines the Safe Return to Port (SRtP) concept and proposes the functional goals of important electrical systems in order to guarantee the power and personnel safety of polar cruise ships. It then provides the topology for the design of redundant electrical systems and analyzes the design scheme of typical systems combined with the realized design objectives and philosophy.
      Results   In the design and construction of small polar cruise ships, the design principle of double redundancy or isolation should be adopted as far as possible in order to achieve the design goal of maintaining the operation of important electrical systems after accidents, thereby greatly improving the life safety guarantee of cruise ship personnel.
      Conclusions  This paper can provide ideas and references for the electrical system design of small polar cruise ships.
