Breakdowns and deteriorated performance of critical rotating equipments can have significant impact on the profitability of a business as the annual capacity utilization of the refinery/Petrochemical plants can fall significantly affecting the top line and bottom line of the business. There are various condition based maintenance techniques that have been introduced for Centrifugal compressors like online vibration monitoring .Also if you analyze the amount of condition based maintenance on a reciprocating compressor is comparatively very minimal and cost of maintenance three times when compared to centrifugal compressor. Centrifugal pump like Sun dyne which is very sensitive to process parameters are not monitored so closely often resulting in major break downs especially in Petrochemical plants like PTA. There is huge amount of process and equipment data is gathered from field in the DCS or other control system which is not utilized optimally for condition monitoring and in most cases like the black box on an aircraft: data gathered and stored so that they are available when there is an eventuality. Wipro OSI PI practice is trying to leverage OSI PI for making use of plant equipment and process related data for rotating equipment condition monitoring.
