Modernization Lessons Learned - Part 1

  1. 1. Modernizations & Migrations Lessons LearnedPart I<br />Laurie R. Ben<br />John Dolenc<br />
  2. 2. Introduction<br />Part I<br />Modernization/Migration Projects Overview<br />Choosing the Approach/Strategy<br />Justification : Where’s the money coming from? ROI<br />Cost Impacts: Where’s the money going? TICC<br />Summary: Part I<br />Part II<br />Risk Mitigation & Best Practices <br />Lessons Learned: What to watch for?<br />Summary Part II<br />
  3. 3. Migration Issues for Management<br />What do we need to do?<br />What do we gain by modernizing the automation system?<br />Who can do this for us? (plan / design / implement / start-up)<br />How much will it cost?<br />How long will it take?<br />How long does the process need to be shutdown?<br />What are the other risks of the process not starting back up on time and in spec?<br />How are the risks mitigated?<br />
  4. 4. Migration Projects Differ from New Projects<br />Documentation may not be readily available or up-to-date<br />Automation hardware needs to fit into existing equipment or free space<br />Small window for installation shutdown or requires hot cutover<br />May need to do project in phases<br />Intensive testing is absolutely necessary to ensure successful start-up <br />Operational improvements derived through better automation are expected<br />

  11. 11. Migration Strategy: Options to Consider<br />As-Found – Migrating “EXACTLY” what is in the legacy system to DeltaV<br />Functional – Migrating the “FUNCTIONALITY” of the legacy system to the DeltaV system using today’s technology<br />Modernization – Applying state of the art applications, including field devices, in addition to functional migration to achieve “BEST IN CLASS” benefits<br />
  12. 12. Migration Scope Options to Consider <br />Replace the entire automation system at one time<br />Cold Cutover<br />Completed Replacement (including field terminations)<br />Marshalling System (minimizing downtime)<br />Hot Cutover<br />Phased approach<br />Vertical (Process Area)<br />Horizontal (Platform Focus)<br />HMI interoperability (Controller and I/O remain)<br />Controller replacement (I/O remain)<br />I/O Card replacement (Field terminations remain)<br />
  13. 13. Hot vs Cold Cutover: Key Economic Driver<br />Cold Cutover <br />Engineering & construction perspective <br />Potential for plant upsets minimized or eliminated<br />Safety Hazards greatly reduced<br />Environmental releases eliminated<br />Manpower/resources deployment flexibility<br />Uncertainties of BAD data reduced (instrument or process problem?)<br />Hot Cutover<br />Economics (no production loss)<br />Operations Perspective: process problems typically taken out of equation, smoother transition <br />Operator & Maintenance Training are simplified, one-on-one<br />Eliminates time-consuming, expensive, and dangerous start-ups (Continuous Industries)<br />
  14. 14. Vertical vs. Horizontal Approach<br />Vertical Migration – Based on migrating one complete automation system/area at a time<br />Horizontal Migration – Based on migrating “equipment type” at a time across automation systems <br />Decision Factors – Operating Philosophy <br />Interim Journey: Operate 2 systems for some period of time?<br />Plant Area at a Time: Can you divide up by Controller or Control file at a time ?<br />Segregated I/O: How is I/O laid out in cabinets? Interchange within areas? How is spare capacity used?<br />Best Practice: Detailed/Meticulous site audit of hardware/field wiring terminations <br />
  15. 15. Additional Drivers that Direct the Migration/Modernization Approach<br />Capital budget restraints<br />Production / Shutdown schedule constraints<br />Legacy system infrastructure layout<br />Free space constraints<br />Equipment obsolescence status<br />Justification driver <br />
