PLANT OPERATION MANAGEMENT(6)

(2) Maintenance Management System The maintenance management system is an integrated computer system utilized for sharing the operation and maintenance records of Fugen as a database and for networking various management systems. It was developed with the aim of laborsaving and improving the reliability of maintenance work as well as collecting data valuable for development of ATR. Since the start of system development in 1979, Fugen has been putting various management systems into operations. Even now systems have been upgraded like applying bland-new technology to the management of system isolation.

(3) Plant Data Collecting System The plant data collecting system was installed for the purpose of obtaining plant process data at the startup test of Fugen. The system has been expanded, improved, and upgraded. It is presently capable of dealing with a large amount of data, including plant operation data and process computer data. In particular, the data processing and display functions have been perfected to enable the provision of easy-to-understand data to users. The system also demonstrates the excellent ability in early detection of plant abnormalities and in analysis of plant behavior during transient change.
