摘要

本文主要研究船舶动力与推进混合动力系统的可靠性建模问题。为了保证可靠性模型的准确性，采用多相马尔可夫方法引入了其运行剖面。可靠性建模是基于特定船舶的。在引入所有运行模式后，计算出了系统的可靠性，并与各特定模式下的可靠性进行了比较。此外，将修复率设为零，也得到了存活函数。结果表明，动态定位A模式的可靠性最低，过境A和ECO A模式的可靠性最高。此外，不同的运行模式具有不同水平的平均无故障时间(MTTF)。mttf之间的差异可以达到近4000运行小时，尽管可靠性差异很小。这可能会进一步影响维护策略，这在可靠性计算中可能并不明显。因此，有必要在设计和运行规划阶段考虑运行剖面进行可靠性建模。

Reliability Modelling of Marine Hybrid Power and Propulsion System Considering Operation Profile

This paper focuses on the reliability modelling of a marine hybrid power and propulsion system. In order to ensure the accuracy of the reliability model, its operation profile is introduced by the multi-phase Markov method. The reliability modelling is based on a particular vessel. The reliability after introducing all the operation modes is figured out and compared with the individual reliability of each specific mode. In addition, the survival functions are also obtained by setting the repair rates as zero. The results show that Dynamic Positioning A mode has the lowest reliability while Transit A and ECO A modes have the highest reliability. In addition, different operation modes have different levels of Mean Time To Failure (MTTF). The differences among MTTFs can reach nearly 4000 operation hours, even though the differences in reliability are quite small. This can further influence maintenance strategies, which may not be apparent from the reliability calculation. Therefore, it is necessary to consider operation profiles for reliability modelling in the design and operation planning phase.
