Document Intelligence for
Refineries & Brownfield Plants
Brownfield digitization, turnaround documentation, and as-built P&ID reconciliation for refineries. Extract decades of engineering knowledge into SAP PM.
Brownfield P&ID digitization at IOCL / BPCL / HPCL / Reliance refineries: 30+ years of paper drawings converted to structured asset registers
Turnaround documentation for CDU, VDU, FCCU, Hydrocracker, DCU, SRU: piping MTO, weld schedules, NDE plans from scanned isometrics
As-built P&ID reconciliation: field redline markups consolidated against original design documents, current-state twin data layer delivered
OISD 118 periodic HAZOP re-validation: 5-year mandatory review cycle with action register digitization and P&ID node mapping
IBR Form IV register automation for refinery pressure equipment: boilers, economisers, superheaters, piping above IBR thresholds
PESO / CCOE licence register for refinery storage, flare system, compressed gas, and explosives-scoped equipment
Mill certificate traceability for turnaround material supply: 180,000+ MTR formats with PO line-item matching
Legacy datasheet digitization: 40 years of instrument, pump, exchanger, column datasheets structured into searchable register
MoC (Management of Change) automation: P&ID revision delta to open PO impact analysis during online modifications
Chief Inspector of Boilers audit preparation: 60-120 day manual cycle compressed to days with live IBR register

HAZOP study consolidation across refinery units: plant-wide action register with closure evidence chain
Why do refineries need document intelligence for brownfield digitization?
Refineries routinely carry 30-50 years of accumulated engineering drawings across expansions, capacity revamps, MoCs, and turnarounds. The authoritative as-built state commonly exists only in paper archives, faded scans, or outdated CAD files. Turnaround planning, IBR Chief Inspector audits, OISD 118 periodic HAZOP reviews, and safety-critical MoC workflows all depend on current-state documentation, which is routinely unavailable without manual reconstruction. Document intelligence automates extraction from these legacy documents into SAP PM / Maximo, enabling modern asset management, predictive maintenance, and regulatory compliance without re-drawing every P&ID. For a typical large refinery (500,000+ tags, 10,000+ P&IDs, decades of documentation), manual digitization is economically infeasible; Pathnovo makes it tractable in weeks rather than years.
What is the typical ROI of refinery document intelligence?
Three quantifiable benefits. First, turnaround documentation cycle time compresses 30-60%; for a typical refinery turnaround where documentation sits on the critical path, that translates to 2-4 weeks of earlier return-to-service at $120,000-600,000 daily production value per unit. Second, regulatory compliance automation eliminates the $360,000-960,000 annual manual cost of IBR / OISD 118 / PESO register maintenance via consultancy. Third, Day 1 SAP PM / Maximo data availability enables predictive maintenance from commissioning rather than requiring 12-24 months of baseline data collection. For Indian PSU refineries running annual capex of $60M-240M on turnarounds and revamps, Pathnovo's commercial footprint is a rounding error against these benefits.
Can Pathnovo process legacy refinery P&IDs?
Yes, this is our largest engagement category. We process P&IDs from any era: 1970s hand-drawn, 1980s-1990s early CAD exports, 2000s PDF, and modern intelligent P&IDs. Faded scans, hand-annotations, handwritten revision markups, and non-standard drawing conventions are all handled natively. Typical brownfield engagement scales to 10,000+ P&IDs with 99.5% contractual accuracy SLA.
How does Pathnovo support refinery turnarounds?
Turnaround workflows benefit from five Pathnovo capabilities: (1) piping MTO generation from legacy isometrics for replacement scope, (2) weld schedule / NDE plan / PWHT tracking per ASME B31.3 and Section IX, (3) mill certificate traceability for incoming replacement materials with PO matching, (4) OISD 118 HAZOP re-validation with P&ID-revision mapping, (5) as-built documentation from field redlines. Typical turnaround cycle shortened by 30-60% on the documentation-critical path.
Do you support brownfield digitization at scale?
Yes. The McDermott reference benchmark processed 10,247 tags across 600 P&IDs with zero QA rejections. Indian PSU refinery brownfield digitization engagements typically run 6-12 weeks and deliver: complete asset register, equipment master with material traceability, IBR / OISD 118 / PESO compliance registers, legacy HAZOP study digitization, and Day 1 handover-ready SAP PM / Maximo load file. Pricing per-page with volume discounts; Indian PSU rate-card compatibility available.
Which Indian refinery operators does Pathnovo serve?
IOCL (Indian Oil Corporation, 9 refineries), BPCL (Bharat Petroleum, 4 refineries), HPCL (Hindustan Petroleum, 3 refineries), Reliance Industries (Jamnagar, world's largest single-location complex), Nayara Energy (Vadinar, formerly Essar Oil), MRPL (Mangalore Refinery, HPCL subsidiary), ONGC Mangalore, Chennai Petroleum (IOCL subsidiary), Numaligarh Refinery (NRL). Each refinery carries concurrent IBR + OISD 118 + PESO + CCOE regulatory obligations; see /compliance/indian-epc-compliance-bundle for the integrated workflow.
Does Pathnovo support Gulf refining operators?
Yes. Active coverage for Aramco downstream (Ras Tanura, Yanbu, Jazan, SATORP, YASREF, SAMREF), ADNOC Refining (Ruwais), QatarEnergy refining (Ras Laffan), PETRONAS Melaka, KPC / KNPC (Mina Al Ahmadi, Mina Abdulla, Shuaiba), Bahrain Petroleum Company (BAPCO). Data residency configurable in AWS Riyadh or Azure UAE North. See /regions/uae-middle-east/saudi-arabia for the Gulf market detail.
How does Pathnovo integrate with refinery SAP PM / Maximo?
Pre-certified connectors for SAP PM S/4HANA and IBM Maximo 7.6 / MAS 8.x. Asset hierarchy, functional locations, work order templates, PM schedules, condition monitoring points, and inspection registers all populated from extracted engineering data. MAS Predict / MAS Monitor initialisation data delivered for Day 1 predictive maintenance activation. See /solutions/engineering-handover for the full handover workflow.
