Abstract
Prognostics and health management (PHM) is an essential means to optimize resource allocation and improve the intelligent operation and maintenance (O&M) efficiency of marine systems and equipment (MSAE). PHM generally consists of four technical processes, namely health condition motoring (HCM), fault diagnosis (FD), health prognosis (HP), and maintenance decision (MD). In recent years, a large amount of research has been implemented in each process. However, there is not any systematic review that covers the technical framework comprehensively. This article presents a review of the framework of PHM in the marine field to fill the gap. First, the essential HCM methods, which are widely observed in the academic literature, are introduced systematically. Then, the commonly used FD approaches and their applications in MSAE are summarized, and the implementation process of intelligent methods is systematically introduced. After that, the technologies of HP have been reviewed, including the construction of health indicator (HI), health stage (HS) division, and popular remaining useful life (RUL) prediction approaches. Afterwards, the evolution of maintenance strategy in the maritime field is reviewed. Finally, the challenges of implementing PHM for intelligent ships are put forward.
Highlights
With the development of modern technology, the level of ship automation and intelligence is gradually improving, and the operation and maintenance (O&M) technology for marine systems and equipment (MSAE) is facing new problems
Through filtering the keywords and assessing the state-of-the-art, we had systematically reviewed more than 300 related articles in the marine field and analyzed different kinds of approaches and applications
The fault diagnosis (FD) section summarized diagnostic methods and applications based on existing research and gave some solutions for MSAE
Summary
With the development of modern technology, the level of ship automation and intelligence is gradually improving, and the O&M technology for MSAE is facing new problems. The ship alarm monitoring system (AMS) relying on human experience and knowledge can no longer meet the condition assessment requirements by maintenance engineers. The traditional ship maintenance modes characterized by corrective maintenance (CM) and planned maintenance (PM) have gradually highlighted the disadvantages of “over repair” and “missing repair” lead to the increasing of ships’ operation costs. With the advancement of comprehensive equipment monitoring, assessment, diagnostics, and prognostics technology, the PHM of MSAE based on a more proactive maintenance strategy has gradually become a new trend of intelligent O&M. Based on the perfect situ monitoring and advanced analysis methods, PHM technologies, approaches, and applications are developing rapidly. Its application objects gradually expand to military, aerospace, ships, and so forth.
