A major EPC contractor in the Gulf region needed to build a complete handover documentation package for a grassroots refinery. The package, containing the tag register, instrument index, and all associated documentation, had to be delivered before a fixed milestone date tied to a contractual payment event worth crores.
12,000 P&IDs spanning eight engineering disciplines, each with different conventions, symbology standards, and revision histories.
The internal team estimated nine months to build the tag register manually at 95% accuracy, not enough for plant operations.
A fixed handover deadline in 14 months with a contractual payment event. Missing it meant deferred revenue plus liquidated damages.
The client had failed handover QA on their previous project due to tag discrepancies between P&IDs and the instrument index.
Ingested all 12,000 P&IDs across eight disciplines, PDFs, DWGs, and scanned drawings from multiple engineering teams.
Our extraction models parsed every tag, instrument, line number, and equipment reference using ISA 5.1 symbol recognition.
Reconciled extracted tags against 3,200 datasheets, flagging every parameter mismatch, orphaned tag, and missing document.
Cross-validated the C&E matrix against the extracted tag list. Found and corrected 23 SIL classification inconsistencies that would have surfaced at SIL verification.
Domain engineers reviewed every safety-critical field, design pressure, temperature, safety classification, and SIL level.
Loaded the verified tag register directly into SAP PM S/4HANA, no intermediate Excel files, no manual upload.
47,000 instrument tags extracted and verified across all eight disciplines.
1,847 discrepancies between P&ID and Instrument Index identified and resolved before QA review.
23 SIL classification inconsistencies corrected in the C&E matrix.
Tag register loaded directly into SAP PM S/4HANA, zero manual data entry.
Completed 11 weeks ahead of the handover milestone.
Zero QA rejections at handover, the first time this client achieved a clean handover.
“We had conducted internal trials on our engineering documents but felt the difficulty of achieving the accuracy required for actual operations. The leap in accuracy Pathnovo delivered compared to conventional approaches was dramatic.”

The contractor's internal team estimated 9 months to build the tag register manually at 95% accuracy, not enough for plant operations. Pathnovo completed the engagement in 14 weeks at 99.5% accuracy, with the contractor hitting the handover milestone 11 weeks ahead of the contractual deadline.
Pathnovo's cross-document reconciliation engine cross-validated every extracted P&ID tag against the 3,200 instrument datasheets, flagging parameter mismatches, orphaned tags, and missing documents. Each discrepancy was tied to the source P&ID number and datasheet reference so the contractor's engineering team could resolve it directly rather than re-investigating the source.
SIL classification inconsistencies between the C&E matrix and the P&ID tag list typically surface at SIL verification, after fabrication, after instrument procurement, and after partial commissioning. Catching them during extraction meant the corrections were made on paper rather than requiring instrument re-procurement or SIS re-verification, each of which would have triggered schedule slip and cost recovery.
Conventional handover practice delivers the tag register as Excel files that the owner's team uploads manually into SAP PM, introducing 4-8 weeks of transcription and reconciliation at handover. Pathnovo loaded the verified tag register directly into the owner's SAP PM S/4HANA instance via pre-certified connector, eliminating manual upload and the associated transcription error class entirely.
The client had failed handover QA on their previous project due to tag discrepancies between P&IDs and the instrument index. By catching all 1,847 discrepancies and 23 SIL inconsistencies during extraction rather than at QA, and by delivering the tag register pre-loaded into SAP PM rather than as a manual-upload Excel, the QA review found nothing to reject. This was the contractual payment event, and it cleared on schedule.
