Generate complete instrument indexes from P&IDs in 48 hours instead of 8 weeks. AI extracts every tag, populates datasheets, and delivers directly into your project format.
In short
Pathnovo's Instrument Index Automation generates a complete instrument index from P&IDs (scanned, CAD PDF, or intelligent) in 48 hours versus 4 to 8 weeks for manual compilation, at 99.5% contractual field-level accuracy. Output covers tag number, type, service description, P&ID reference, loop number, range, signal type, location, and SIL classification, with auto-populated instrument datasheets, DCS / PLC / SIS I/O lists (Yokogawa Centum, Honeywell Experion, Emerson DeltaV, Siemens PCS7, ABB 800xA), control valve and PSV schedules per ASME VIII / API 520 / 521 / 526, and revision delta reports for MoC. Trained on ISA 5.1 instrumentation symbology with project-specific tag conventions (Aramco SAES, ADNOC, PETRONAS, IOCL / BPCL / HPCL / ONGC / GAIL). Integrates with SAP PM S/4HANA, IBM Maximo, Hexagon SmartPlant Instrumentation, and AVEVA Instrumentation. Reference benchmark: McDermott engagement at 99.8% measured extraction accuracy. Credit-based pricing with full platform on every paid tier; scoped paid pilot on the Starter tier before scale-up.

| Compared on authoring vs extraction | Pathnovo | Them |
|---|---|---|
| Hexagon SmartPlant Instrumentation | Extracts instrument data from existing PDF / scanned P&IDs in 48 hours; no license, no migration | Database authoring tool; $500K+ license + $2-5M typical migration; cannot read legacy drawings |
| AVEVA Instrumentation | AI extraction with 99.5% accuracy SLA; output to SAP PM, Maximo, Excel, AVEVA AIM | Manual data entry workflow; requires AVEVA-authored source drawings |
| Manual instrument index compilation | 48-hour turnaround at 99.5% accuracy; full platform on every paid tier | 8-week typical timeline; manual data entry; no contractual accuracy guarantee |

Auto-populate instrument datasheets from P&ID data. Process conditions, material specs, and set points extracted and mapped to standard datasheet formats.
Generate complete DCS, PLC, and SIS I/O lists directly from P&ID instrument data: signal types, ranges, engineering units, alarm set points, trip set points, loop assignments, and safety classification derived automatically. The only tool globally that produces configuration-ready I/O lists from PDF or scanned P&IDs, including C&E matrix cross-referencing and SIL classification. Works for any control system: Yokogawa Centum, Honeywell Experion, Emerson DeltaV, Siemens PCS7, ABB 800xA, Rockwell PlantPAx.
Auto-generate control valve lists, safety valve registers, manual valve lists, and equipment schedules directly from P&ID data. Complete specification data (size, rating, material, trim, actuator, fail position, Cv, set pressure, orifice letter, inlet/outlet sizing) extracted automatically and formatted for RFQ, PO, and handover packages. ASME VIII, API 520 / 521 / 526 compliance built-in. Works on any P&ID format including scanned legacy drawings.
Pathnovo generates a complete instrument index from P&IDs in 48 hours, compared to 4-8 weeks for manual compilation. This includes tag extraction, datasheet cross-referencing, and output formatting.
Tag number, instrument type, service description, P&ID reference, loop number, location, range, material, process connection, signal type, and safety classification. Additional custom fields can be added per your project requirements.
Yes. We map output to your project-specific instrument index format. Whether you use a standard EPC template or a client-mandated format, we deliver in your exact column structure.
Manual compilation: 4-8 weeks, 90-95% accuracy, no SLA, Excel-only output. Pathnovo: 48 hours, 99.5% accuracy SLA, direct system integration, full auditability.
Yes. Extracted instrument data can be loaded directly into Hexagon SmartPlant Instrumentation, AVEVA Instrumentation, and other engineering data management systems.
SIL 1 through SIL 4 classifications are extracted from the SIS specification and applied to every safety-instrumented function in the index. BPCS / SIS independence is verified, and orphaned trip loops (no C&E entry) are flagged. The output is IEC 61511 compliant for safety audit submission and feeds the HAZOP safety intelligence workflow for cause-and-effect verification.
Yes. A scoped paid pilot on the Starter tier (1,000 credits per month) is sufficient to extract around 50 complex P&IDs (20 credits each) and validate the instrument index output against your existing manual deliverable. Most pilots run on a single process unit (40 P&IDs, 200 loops) and complete inside Starter, then scale to Professional (5,000 credits/month) once accuracy and throughput are validated. See our pricing page for full plan details.
Yes. Aramco SAES instrumentation standards (including SAES-J series), ADNOC engineering standards, QatarEnergy, KOC, and Petronas instrumentation conventions are pre-configured. Indian PSU instrumentation standards for IOCL, BPCL, HPCL, ONGC, GAIL are equally supported. Data residency for these engagements is configurable to AWS Riyadh, Azure UAE North, Azure India Central, or AWS Mumbai per the procurement standard.

Manual instrument index compilation for a typical EPC project with 5,000-10,000 P&IDs takes 4-8 calendar weeks with a team of 3-5 engineers. The process involves reading every P&ID, manually entering tag data into spreadsheets, cross-referencing datasheets, and performing QA checks. Pathnovo automates this to 48 hours with 99.5% accuracy, 60x faster at higher quality.
For a mid-size EPC project, manual instrument index preparation costs $150,000-$400,000 in engineering hours, produces 90-95% accuracy with no SLA, and requires weeks of rework when P&ID revisions arrive. The hidden cost is delayed handover, every week of delay can cost the contractor 1-2% of contract value in liquidated damages. With Pathnovo, the same workflow runs on credit-based pricing with the full platform included on every paid tier, and a scoped paid pilot on the Starter tier to validate accuracy on your own drawings before scale-up. See [our pricing page](/pricing) for full plan details.
