Case Studies
Every case study below is a project where we extracted, reconciled, and delivered verified engineering data, with measurable commercial outcomes.
What You Will Find
These case studies document real engineering document intelligence projects delivered for EPC contractors, petrochemical plants, and manufacturing teams, extracting structured data from P&IDs, HAZOP registers, mill test reports, and datasheets into enterprise systems under strict accuracy and timeline commitments.

Major EPC Contractor
Grassroots Refinery, Handover Documentation Package
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.

“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.”

HAZOP Action Register Digitisation, OISD 118 Compliance
An Indian petrochemical plant faced an upcoming OISD 118 audit. Their 2,400-page HAZOP study, completed in 2019, had not been updated despite two P&ID revision cycles. The plant needed proof that all HAZOP actions were tracked and that no nodes referenced superseded drawings.

“For the first time, our process safety team had a structured, queryable HAZOP register linked to current P&ID revisions. We found 31 nodes referencing superseded drawings we had never known about.”

MTR Traceability Register, 180,000 Mill Certificates
An EPC contractor in India needed 100% material traceability across 180,000 mill certificates from 400 global mills before the asset owner's inspector would release final payment. The QA team was manually keying data at 15 minutes per certificate.

“We would have spent three months building this manually and still had gaps. Pathnovo gave us the gap report in two weeks that would have taken a QA team a month to produce.”

Tier-1 Global EPC Contractor
Greenfield Gas Processing Plant, Malaysia: P&ID Data Extraction + Tag-Document Register
A tier-1 global EPC contractor delivering a greenfield gas processing plant in Malaysia needed structured engineering data extracted from 600 P&IDs across eight process units. The contractor's internal estimate was 9-12 months to build the tag register manually at 95% accuracy, with significant residual risk on safety-critical fields. The owner-operator handover specification required CFIHOS 2.0-compliant data delivery within an 18-month window from mechanical completion, with contractual liquidated damages for late handover.

“We had run internal trials on AI extraction before. The accuracy was not where we needed it for owner-operator handover. Pathnovo delivered measured 99.5% accuracy across 10,247 tags. That is the first time we have seen production-grade results on an engagement of this scale.”

Brownfield P&ID Digitisation, Indian PSU Refinery: 8,400 P&IDs across multi-decade baseline
An Indian engineering consultancy delivering a brownfield digitisation programme at a major Indian PSU refinery needed structured engineering data extracted from 8,400 legacy P&IDs spanning the original 1980s commissioning era plus three subsequent revamp phases. The PSU client required CFIHOS-aligned asset register output plus full IBR + OISD 118 + PESO + CCOE compliance register population, all delivered within the 18-week digitisation phase window before the next turnaround cycle. The consultancy's prior practice was 6-9 months of manual digitisation per revamp phase.

Cycle-Time Saving
“Manual digitisation at our scale meant losing 6-9 months per revamp cycle to documentation work alone. Pathnovo collapsed that to 16 weeks with the full Indian regulatory bundle alongside. The PSU client accepted the digitised baseline at the first review, which never happened on manual baselines.”

Refinery Turnaround Piping MTO from Legacy Scanned Isometric Drawings
An Indian PSU refinery running a major turnaround cycle on a hydrocracker unit needed piping material take-off (MTO) extracted from 2,400 legacy isometric drawings to size the replacement material procurement for the turnaround scope. The refinery's isometric archive was a multi-decade mix of 1990s blue-line prints, 2000s PDF scans, and 2010s ISOGEN PCF / IDF exports. No 3D plant model existed for the hydrocracker scope. The refinery's internal turnaround planning team estimated 12-16 weeks of manual MTO extraction, against a turnaround start date 6 weeks away.

Time Saved vs Manual
“Manual MTO extraction at our scale during a turnaround window is the bottleneck that delays material procurement and ultimately delays the unit's return to service. Pathnovo collapsed 12-16 weeks of MTO work to 9 days. The procurement team received clean structured MTO 5 weeks before turnaround start. That is the first time we have had material on site ahead of the turnaround instead of catching up during the shutdown.”
