On Wednesday, August 26th our own Eric Allen presented on an Industrial Society of Automation (ISA) Webinar titled "Retag or Revalidate? Understanding the Differences + Industry Best Practices and Technology." The Webinar was well-attended, with over 50 call-in users signed in during the presentation, and offered attendees an opportunity to learn about industry-best practices for LDAR retags and new technologies in the industry. Furthermore, Ei educated attendees on a new approach to achieve LDAR inventory compliance which is being pioneered by Ei's powerful new tablet-based EiMOC™ and FieldTech Toolbox™ software, called an LDAR Revalidation.
What is an LDAR Revalidation
During an industry-standard LDAR retag, your contractor hangs all new tags on the LDAR components in the field - a very costly and time consuming process. During an LDAR revalidation, you forego the "start over again" approach of a retag, but instead perform a complete walk-down of every component with highlighted P&IDs and an entire backup of the site's LDAR database - fixing inventory issues on the spot as you identify them. Plainly put: just "fix the issues," and use technology to achieve compliance by ensuring every component is revalidated.
The best part of a revalidation is that the only thing you need is an intrinsically safe tablet running Ei's software - it works with whatever format of drawings you have (CAD format, .PDF, or scanned paper P&IDs) and data from your LDAR database.
Ei's Best Practice Checklist
One of the goals of the presentation was to leave attendees with resources they can use on their next project - irrespective of the contractor or technologies they use. During the presentation, Ei shared a "Best Practice Checklist" for executing these LDAR retag and revalidation projects, broken down into the four main phases of project execution, as follows:
- Determine scope: retag or revalidate?
- Acquire the NEWEST version of the P&IDs to highlight
- Meet with Process Engineering to review chemical speciation
- List the “Stream Name” on the highlighted P&IDs
- Develop and agree upon robust project SOPs to guide highlighting, flagging, tagging, and documenting
- Weekly Project Status Updating (WPSU) on flagging, tagging, and documenting
- Track contractor performance - accountability and project forecasting
- Ensure EVERY component is walked down (in a Revalidation)
- Record the tag numbers on the P&IDs
- Record the “Stream Name” from the P&IDs in the database (for emission estimating)
- Minimize tag loss
- Report on each tag gap
- Track and report on A-Tags to minimize missed tags in the tagging step
- Merge NewTag information with the OldTag history (for retags)
- Perform field-verification of OldTag - NewTag linking to minimize Title V deviations
- QA/QC, QA/QC, QA/QC the inventory data
- Provide field redlines to LDAR coordinator for CAD to review
- Prepare project closeout report (Final Deliverables)
If you have LDAR inventory or compliance concerns, use this checklist as a guide to ensure you and your contractor are planning on executing an industry-leading project which will achieve compliance, eliminate headaches, and reduce costs!
