This week, we’re using SOPs and FieldTech Toolbox™ technology to navigate the pain points of flagging LDAR equipment based on P&ID markups. We know that flagging marked-up P&IDs is the most critical part of any retag because if a misstep occurs tagging and documentation suffer. In this post, we’ll show you how we do a few things differently to overcome flagging pain points.
(Also, from here on out, each blog will have a giveaway at the end of each post. Can’t wait to get there, right? Read, then see below!)
When it comes to LDAR retagging, there are a number of factors we can’t control - like weather (believe us, we lost 2 days to rain last week). But with P&ID technology, we make up time quickly. One of our LDAR professionals even flagged 17 P&IDs in a single day, leaving us at 80% flagging completion after 2 weeks - not bad for a tank farm with over 100 P&IDs.
The reason we’re on track right now (despite the rain) are the things we can control, and what we do differently to stay on top of things:
1. Flagging out the Unit. The two common ways of flagging P&IDs is to either write information onto colored streamers or onto flagging cards (see right) for a documenter to reference during inventory. This process is time consuming, as you are just writing information (Unit, Drawing, Stream, State, etc.) from the P&IDs onto cards/flagging ribbon.
What we do that’s different: We do away with flag cards altogether because intelligent P&IDs and the FieldTech Toolbox™ contain the unit, drawing, stream, and other necessary information. That means we can simply hang flagging tape (red flags = “no”, green flags = “go”), which allows us to flag twice as fast.
2. P&IDs to Completion. When all you have is paper P&IDs, it becomes a challenge to ensure that P&IDs are flagged to completion. We suggest marking off each pipe on a P&ID as it is flagged, which can be a burdensome task to manage if you have multiple flaggers redlining dozens/hundred of P&IDs.Normally, this would mean walking around with a stack of paper P&IDs and component inventory data printed from spreadsheets.
What we do that’s different:
A. Search and Verify Equipment with Electronic P&IDs. With the use of electronic P&IDs, our professionals easily locate equipment in the field. For example, when we search for a flow transmitter ID tag, we can use a hyperlink to find where the equipment is within a stack of drawings. The gif to the right shows how we can locate a tank and associated control valve in seconds.
B. Perform Concurrent LDAR Data Review During Flagging. With electronic P&IDs and all existing LDAR inventory data in the tablet, our professionals are empowered to search for equipment in the existing database by location description or tag. This is particularly helpful if any questions arise during flagging about the accuracy of P&ID markups and/or historical tagging. The gif to the right shows all of the components within a LeakDAS(R) database associated with a specific tank (e.g., Tank 200-2) referenced in the Location Description field of the LDAR database.
3. QA/QC Field Flagging P&IDs. We use two types of QA/QC for flagged drawings. The first is good ‘ol fashioned field review - there’s no substitute for field verification provided that you have unlimited time and project budget. The second is something we do differently.
What we do that’s different:We combine field flagging redlines and notes electronically each day, which we call “merging markups.” With this electronic management system for tracking redlines and markups, we are able to track progress, combine work efforts, as well as allow each field professional to see the work of each other on a daily basis.
We can’t understate how important it is to “get it right” the first time for flagging to minimize tagging and documentation errors. The FieldTech Toolbox™ is our solution that provides new and better ways and equips our team with P&IDs, process information, and LDAR data in an offline environment.
Oh, and this week’s give-away is our tagging SOP, which will get you in the mood for next week’s tagging post. Want a copy? Shoot us anemailand we’ll send it your way.
