Abstract: At present, the data from ship manufacturing to operation is mainly transmitted by description documents. A large number of documents make the initialization of ship maintenance management system cumbersome and difficult.In order to solve this problem, firstly, the data demand of ship maintenance is analysed, and the data generated in the upstream manufacturing process is sorted out. A data transmission mechanism based on the data demand of ship maintenance management system is constructed by using handle identification analysis system. Then, the data transmission from ship manufacturing to operation process is illustrated by taking the domestic sewage treatment plant of Changshi 10 as an example. The data transfer mechanism based on identification analysis system can effectively improve the efficiency of data transfer from ship manufacturing to operation, reduce the difficulty of initialization of maintenance management system, and improve the level of ship maintenance management.
