Standardization and Systematization of Control Room Operation through the Implementation of an Intelligent Sequence Control System

This paper presents the results through the implementation of IT-based systematization of control room operation. IT-based systematization, consisting of an Intelligent Sequence Control System (ISCS) for automatic operation and an Advanced Monitoring System (AMS) for automatic monitoring, on the other hand, permits ready achievement of the recommendation target. Moreover, ISCS/AMS are very effective tools by which operators can easily systematize their know-how. Over 30 ISCS/AMS systems have been implemented at petroleum /petrochemical refineries operated by Idemitsu Kosan in Japan since the year 2000. As a result of the application of ISCS/AMS systems, the following results have already been achieved: 1) Manual operation frequency has been reduced by 93% through the application of ISCS to shutdown operations. 2) Alarm frequency has been reduced by 88% through the application of ISCS to shutdown operations. 3) Operational knowledge has been partially systematized by ISCS/AMS. 4) ISCS/AMS have contributed to know-how sharing and to the standardization of a high level of operational expertise.
