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.
- 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, annotated PDF
- 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
- 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
