For the newly-built Waterway Bureau dredger -long whale
II, which is self-propelled and trailing suction, it establishes the
ship maintenance program optimization system in life cycle
based on PHM.
In figure 4, the optimization system is divided into three
subsystems, including the shipboard monitoring and
management subsystem, the maintenance center management
subsystem and the ship-to-shore radio communication
subsystem. The shipboard monitoring and management system
monitors the major equipment and conducts the maintenance or
maintain of the ship. The subsystem carries out the data
acquisition, transmission and monitoring independent. The
maintenance center management subsystem receives the online
real-time data of the shipboard monitoring subsystem and
completes functions of condition monitoring, health
assessment, failure prediction, maintenance management and
emergency dispatch. The ship-to-shore radio communication
subsystem is the approach to connect the shipboard monitoring
and management subsystem and the maintenance center
management subsystem. It completes the ship-shore wireless
communications and data transmission.
