3. IPECJAFPilgrim Pilgrim’s Objective: A data archival/retrieval system for plant process information –Store data beyond the 3 days available on the Plant Process Computer –Deliver plant process data to the Engineers’ desktop –Integrate multiple systems into a single viewer 

4. IPECJAFPilgrim How Did We Do It? Dedicated PI server Added 180 Gigabytes of storage medium –Approximately 8500 tags –Over 30 years of data at current resolution Connected the process computer to the business network –Firewall connection 

5. IPECJAFPilgrim ProcessBook & DataLink Training Used a vendor for initial user training –About 20 power users Provided our own on-site instruction for PI –Allowed a significant portion of employees to be trained –Saved over $135,000 based on vendor training fees –Developed in-house expertise 

6. IPECJAFPilgrim Wireless Paging from PI OSI Email Notification Manager Uses company e:Mail or Pagers Employee Notification of PI Events –Plant power level at any selected time –Process changes at selected tag limits 

7. IPECJAFPilgrim PI Feedback! Thanks for the PI data from 8/31/2000. As a result of having this data I can clearly show that on 8/31/2000 the HPCI system was operating as expected and would have performed it's safety function if required. On this date the system test was run. After the Labor Day Holiday during data review, a discovery was made that one part had failed. The necessary data to support system operability calls was no longer available on the Plant Process Computer. We were at risk for an unavailability hit of over 1000 hours on the HPCI performance indicator. However, since this data was available from PI, we only had to take a 12 hour "fault exposure" hit. 

8. IPECJAFPilgrim Informative Trend Displays Problem developed with the turbine Differential Expansion A simple PI trend display allowed for a comparison of steady state values –Shell expansion –Differential expansion of shell and rotor

9. IPECJAFPilgrim Informative Trend Displays Conclusion The PI display: –Clearly demonstrated an instrument problem –Prevented unnecessary outage time to investigate
