P&ID extraction for pipeline and midstream.
A midstream corridor runs thousands of kilometres and dozens of stations, each built by a different EPC against a different revision of the operator's standards. The corridor-level instrument register is the union of all of them.
What pipeline and midstream drawings carry.
- Compressor stations carry vibration, temperature, gas detection, and ESD SIS scope
- Custody-transfer metering is audited under weights-and-measures regimes. Extracted scope filters into a separate register
- Pipeline integrity instruments, cathodic protection, leak detection, ILI tool tracking are spread across the asset. The extraction is the consolidation step
- Cross-jurisdiction pipelines, US, Canada, interstate vs. Intra-state drive different documentation regimes. The extracted dataset supports whichever regulator asks
- Liquid pipelines, crude, NGL, products and gas pipelines carry different instrumentation density and SCADA architectures. Differences surface in the equipment list
- Scraper traps, valve sites, and check-valve stations are thin drawings, sometimes one page but carry SIS-classified ESD valves
- Tank terminals at pipeline endpoints behave like a tank farm. Processed as a separate workspace with custody-transfer scope filtered out
- Older drawings carry imperial units and ASME B31.4, B31.8 spec callouts. Line list preserves them as drawn
What the extraction delivers.
- Per-station I/O list, compressor or pump station, metering station, scraper trap
- Aggregated corridor instrument register
- Custody-transfer metering audit subset
- Cathodic protection and leak-detection instrument scope

Common questions
Can Tagsight handle 10 plus stations on a single pipeline as one consolidated project.
Each station gets its own workspace. Drawing sets and revision cycles run independently. A corridor-level rollup workspace aggregates per-station documents into a single instrument register for operating-company auditors.
How is custody-transfer scope flagged.
Filter the extracted set on the CT prefix or station-specific tag convention. Export the subset into a separate audit register and feed it into weights-and-measures documentation independently of the operational dataset.
Does this work on liquid and gas pipeline drawings the same way.
Yes. Liquid pipelines carry pump-station drawings. Gas pipelines carry compressor-station drawings. Tag conventions and instrument density differ, but document shape, I/O list, instrument index, equipment list is the same.
Can it process valve-site and scraper-trap drawings that are only one or two pages.
Yes. Single-page drawings extract the same way as multi-page sets.
How is leak-detection instrumentation captured.
Leak-detection analyzer transmitters and pressure-deviation instruments extract as part of the instrument list with service annotation preserved. Filter the corridor register by service to produce a leak-detection subset for API RP 1175 documentation.
