P&ID extraction for oil & gas.
Oil and gas P&IDs accumulate. A turnaround pack rarely matches the as-built it replaced, the operator overlay on top of ISA 5.1 changes with the asset, and the same set can carry three CAD vintages before the next revision freeze.
What oil & gas drawings carry.
- Operator tag conventions read as drawn. NORSOK, Shell DEP, Aramco SAES, ADNOC AGES, Equinor TR, BP RP, Petrobras N, and in-house dialects alongside ISA 5.1
- SIS scope is identified from drawing markers, dedicated SIS lines, tag prefixes, annotations and exported on a separate sheet from BPCS rows for IEC 61511 audit
- Wellhead panels and skid drawings often arrive as scanned PDFs or field photographs. PNG, JPG, TIFF supported, bbox source preserved per row
- Large sets, refinery revamps, LNG commissioning, 100 plus pages process as a single workspace with cross-page connector matching
- FPSO topsides and subsea umbilical drawings carry NORSOK I-005 system numbering and asset-specific prefixes. Read as drawn, not retranslated
- Sour service lines. NACE MR0175, ISO 15156 callouts captured in the line list spec column where the drawing prints them
What the extraction delivers.
- Classified I/O list with AI, AO, DI, DO and SIS, BPCS separation
- Equipment list. Pumps, vessels, tanks, exchangers, compressors with tag, type, description
- Line list with size, pipe spec, service, joinable back to instruments
- Valve list with fail position, actuator type, connected equipment
- Process variable, range, and protocol where captured on the drawing
- Revision comparison feeding MOC documentation packages
- Exports to TIA Portal, Studio 5000, PLCCreator, DEXPI, Excel

Regulatory context.
- OSHA PSM 1910.119, US drives MOC discipline for covered processes
- EPA RMP overlaps PSM with environmental documentation
- IEC 61511, ISA 84 enforces SIS lifecycle including proof-test cadence
- API RP 752, 753 facility siting references P&ID-derived equipment locations
- PHMSA Part 192, gas and Part 195, liquids cover pipeline integrity documentation

Common questions
Does this work on scanned legacy oil & gas P&IDs.
Yes. Scanned PDFs and image uploads, PNG, JPG, TIFF are supported. You review and adjust every row in the canvas before export.
How does SIS, BPCS separation work.
SIS instruments are identified from drawing markers, dedicated SIS lines, tag prefixes, annotations and exported on a separate Excel sheet from BPCS rows. Sign-off can run independently.
Can I handle a 200-page drawing set for a refinery unit revamp.
Yes. Pages process in parallel, so review can begin on page 1 while later pages are still working. The review canvas groups instruments by page so you can work through them in order.
Does this help with MOC documentation.
Yes. Upload two revisions as separate projects, then run revision comparison for an added, removed, modified diff. Export the Change Report and save the comparison to the workspace audit trail.
How does the extraction handle offshore and FPSO drawings.
Same pipeline as onshore. NORSOK I-005 system numbering and asset-specific prefixes are read as drawn.
Can it extract from wellhead panel photographs taken in the field.
Yes. PNG, JPG, TIFF are supported. Photograph quality and angle affect confidence. Flagged rows are surfaced in review.
