Research on PHM technology application of ship maintenance program optimization

In order to change the current disadvantages of traditional ship maintenance concept, this article plans to apply the technical method of prognostics and health management (PHM) to improve equipment maintenance program and repair schedule. In the meantime, this thesis takes account into the example of the dredger power system of the Waterway Bureau to establish the PHM optimized system of life cycle ship maintenance program, which include the system architecture, work platforms and optimize processes.
