Review of condition monitoring and fault diagnosis for marine power systems

The use of condition monitoring and fault diagnosis (CMFD) in marine power systems significantly influences ship safety. This study divides the development of CMFD for marine power systems into three periods and reviews the content, state and limitations of CMFD research for each period. According to the research achievements and engineering experience of the authors’ team, typical application cases are introduced for CMFD in ships, including CMFD platforms on engineering ships, salvage ships, container ships and ro-ro ships powered by solar photovoltaic systems. Finally, prospective research directions are proposed for CMFD in marine power systems, considering the research status of CMFD and the trend toward intelligent and eco-friendly ships.
