Abstract

The development and implementation of machine learning and deep learning algorithms has opened up new possibilities in industry. Maintenance of industrial assets has received wide interest from scientists and practitioners. Condition-based maintenance (CBM) has proven to be necessary to reduce downtime and the cost of repairs and inspections, and to predict and prevent faults. In the maritime industry, marine engines are complex systems that must work in a rough environment; therefore, implementing safe, reliable, and efficient maintenance strategies is challenging. In this context, artificial intelligence (AI) algorithms have shown high reliability and versatility with respect to traditional model-based and knowledge-based techniques. In this work, we propose an unified framework explaining the implementation of suitable AI algorithms to predict the main faults affecting the performance of a marine engine. By an accurate analysis, aging and catastrophic faults are the most common ones. Then, we describe strategies to detect these two types of faults. We also describe the requirements that a decision support system should satisfy to integrate the algorithms for applying an innovative CBM strategy into real-life scenarios. Finally, we present the challenges and provide some suggestions for future research. In summary, the main finding of this work is the framework integrating AI-based efficient strategies for predicting aging and catastrophic faults with significant advance. In detail, prediction of catastrophic faults gains nearly 30 seconds with respect to a classical prediction method. These findings enable us to effectively implement CBM of marine engines considered in this research.
