This study presents the state-of-art and future trends of the maintenance approaches to ship machinery systems. A systematic review process is conducted to identify relevant literature. Firstly, literature is examined by bibliometric analyses based on the determination of the distribution of papers by years, the top authors, papers, journals, and organisations. Then, studies in the literature are reviewed and presented. In addition, the advantages and difficulties of each maintenance strategy are discussed. Finally, an effective maintenance policy that can implement in new ship concepts such as autonomous marine vessels is introduced in line with the information from the literature. In the future, it is believed that maintenance practices will be performed via the condition-based approach when the evolution of followed maintenance operations in ship machinery systems is examined. However, it should be underlined that more effective and powerful maintenance management can be achieved by supporting the system performance monitoring with reliability and risk approaches.

这项研究介绍了船舶机械系统维护方法的最新技术和未来趋势。进行系统的审查过程来识别相关文献。首先，根据按年份、顶级作者、论文、期刊和组织确定论文分布的文献计量分析来检查文献。然后，对文献研究进行回顾和介绍。此外，还讨论了每种维护策略的优点和困难。最后，根据文献中的信息，介绍了可以在自主船舶等新船舶概念中实施的有效维护政策。将来，人们相信，在审查船舶机械系统后续维护操作的演变时，将通过基于条件的方法进行维护实践。然而，应该强调的是，通过可靠性和风险方法支持系统性能监控，可以实现更有效和更强大的维护管理。
