Abstract

The purpose of the special issue is to aggregate papers on new research findings and developments in Condition Monitoring and Fault Diagnosis for Marine Propulsion Systems. Marine propulsion system is the heart of a vessel. Its normal operation ensures the security and efficiency of the trip. However, due to particular working conditions, the hull is prone to deflection and hence speeds up the degradation of the key components in the Propulsion system. A simple failure of the main diesel engine or a crack on the propeller blade may lead to malfunction of the propulsion system. Condition monitoring and fault diagnosis (CMFD) can yield an advance warning of impending failure in the system, thereby helping in maintenance and corrective actions and reducing unscheduled maintenance expenses. Therefore, this special issue may exchange recent progress in advanced techniques to improve reliability and efficiency of the health monitoring and fault diagnosis for the marine propulsion system.

The topics discussed in this special issue include: vibration analysis and oil analysis via innovative signal processing methods, new type sensors and measurement system, novel monitoring and maintenance theories, etc.
