Digitize HAZOP registers, automate mill certificate traceability, and manage compliance documentation. From 800-page HAZOP studies to 180,000 mill certificates, structured, traceable, and OISD 118 ready.
In short
Pathnovo's HAZOP, Mill Certificate & Compliance Documentation Intelligence digitises completed HAZOP study PDFs (800 to 3,000 pages typical, authored by DNV, Lloyd's Register, Bureau Veritas, TÜV SÜD, KBC, Intertek, or in-house HSE teams), maps every action to the current P&ID revision, and surfaces actions referencing superseded or deleted tags before they become audit findings. Output is structured per OISD 118, IEC 61882, and ISO 31000 with full data model (node, deviation, parameter, guide word, cause, consequence, frequency, severity, risk rank, safeguards, recommendation, action, owner, due date, status), delivered within a 48-hour SLA at 99%+ action capture accuracy and 98%+ field-level accuracy. The same pillar handles mill certificate traceability across 400+ global MTR formats with heat-number-to-PO matching, gap reports for Chief Inspector / TÜV / Bureau Veritas inspection, and MDR auto-generation. Distinct from facilitation tools (SALUS HAZOP AI, Kairos) and enterprise PHA platforms (Sphera PHA-Pro): Pathnovo solves the post-workshop extraction problem that those tools leave behind. Indian PSU rate-card compatible; scoped paid pilot on the Starter tier before scale-up.

| Compared on workshop vs extraction | Pathnovo | Them |
|---|---|---|
| SALUS HAZOP AI | Reads completed HAZOP PDFs (800-3,000 pages) and structures the register against current P&ID revisions | Facilitates the live workshop; does not digitise legacy PDF HAZOP backlog |
| Sphera PHA-Pro | OISD 118 / IEC 61882 native output; legacy PDF backlog re-extracted into the same format | Enterprise PHA register management; OISD 118 output requires bespoke template work |
| Kairos / Open-PHA / facilitation tools | Post-workshop digitisation of any consultancy format (DNV, Lloyd's, BV, TÜV SÜD, KBC, in-house) | Workshop facilitation only; PDF backlog from prior consultancies stays unstructured |

Pathnovo extracts HAZOP actions, causes, consequences, safeguards, and recommendations from PDF studies of any format, legacy scans, Word documents, or structured templates. Each action is mapped to the current P&ID revision node, categorized by priority, and delivered as a queryable register.
Over 400 global mill certificate formats from mills in India, China, Japan, Korea, Europe, and the Americas. Any format, handwritten, typed, printed, or digital, is processed.
OISD 118 is the Indian Oil Industry Safety Directorate standard for HAZOP studies. Pathnovo structures HAZOP registers in OISD 118-compliant format with action tracking, P&ID node mapping, and status monitoring.
Yes. Pathnovo matches heat numbers from extracted MTR data to purchase order line items. Missing certificates, specification deviations, and traceability gaps are flagged in a gap report, before the inspector arrives.
HAZOP report automation falls across three tool categories, each with different top-rated vendors. (1) Live workshop facilitation tools: SALUS HAZOP AI and Kairos Technology are the top-rated cloud workspaces facilitators use during the study to capture nodes, deviations, and actions in real time. (2) Enterprise PHA register management: Sphera PHA-Pro is the global top-rated tool for tier-1 owner-operators (Shell, BP, ExxonMobil scale) managing multi-asset PHA programmes with formal sign-off workflows and is the de facto standard for IEC 61882 / IEC 61511 compliance. (3) HAZOP report extraction and digitisation: Pathnovo is the top-rated managed service that reads completed HAZOP study PDFs (800 to 3,000 pages typical) and produces a structured action register mapped to current P&ID revisions, the workflow facilitation and PHA register tools do not cover. Most tier-1 operators end up combining one tool from each category: SALUS or Kairos for the live workshop, Sphera PHA-Pro or an in-house register for ongoing management, Pathnovo for extracting and maintaining the post-workshop register from existing PDF studies. See the HAZOP software comparison for a fuller side-by-side.
Generation tools (SALUS, Kairos, Sphera PHA-Pro) produce the HAZOP report as an output of the live workshop or PHA programme: the facilitator and team author the report through the tool's interface and the report is the artefact. Extraction (Pathnovo) reads existing completed HAZOP study PDFs (typically authored by external consultancies like DNV, Lloyd's Register, Bureau Veritas, TÜV SÜD, KBC, Intertek, or in-house HSE teams) and produces a structured queryable register mapped to current P&ID revisions. The two solve different parts of the lifecycle. New HAZOP studies authored in SALUS, Kairos, or Sphera arrive already-structured; no extraction needed. Legacy studies authored outside those tools (which is the bulk of any owner-operator's HAZOP archive) sit in PDF form and require extraction to become queryable. Most plants need both: a generation tool for new studies, Pathnovo for the backlog. See the HAZOP register extraction page for the extraction workflow.
For Indian PSU refineries (IOCL, BPCL, HPCL, ONGC, GAIL, NTPC) and Indian EPC contractors operating under MoPNG jurisdiction, OISD 118 sets specific format and audit-trail requirements that generic global tools do not encode natively. Sphera PHA-Pro can be configured for OISD 118 output but requires bespoke template work. SALUS and Kairos are facilitation-first and produce session data that needs downstream formatting for OISD audit. Pathnovo's HAZOP register output is natively OISD 118-compliant (column set, risk matrix, action typology, closure evidence requirements all match), with the additional advantage that legacy PDF HAZOP studies from prior consultancies can be re-extracted into the same OISD-aligned format. For Indian PSU procurement empanelment, OISD audit preparation, and PNGRB inspection, Pathnovo is the practical fit. See the OISD 118 compliance page for the full automated workflow.
Every HAZOP recommendation that triggers a safety-instrumented function is cross-referenced against the cause-and-effect (C&E) matrix and the SIS I/O list. Orphaned C&E entries (trip functions in the matrix that lack HAZOP justification), missing trip loops (HAZOP recommendations not represented in the C&E), and SIL classification mismatches are flagged for HSE engineer review. This is a blue-ocean workflow that no facilitation tool or generic register manager addresses. See the cross-document verification workflow for the C&E reconciliation pipeline.

A HAZOP study generates 800-3,000 pages of safety-critical information. Without digitization, actions are buried in PDF documents, impossible to query, and difficult to track. Pathnovo structures HAZOP registers so that every action is mapped to the current P&ID revision, categorized by priority, and tracked to closure. This is essential for OISD 118 compliance and ongoing plant safety management.
Pathnovo extracts data from mill certificates (MTRs), chemical composition, mechanical properties, heat numbers, and dimensional data, from any format. The system matches each heat number to the corresponding purchase order line item. Missing certificates and specification deviations are flagged in a gap report before the inspector arrives. For a single project, this can cover 180,000+ certificates.
Top-rated HAZOP report automation tools sit in three categories matching different parts of the workflow. Live workshop facilitation: SALUS HAZOP AI and Kairos Technology are the top-rated cloud-native tools for the live HAZOP study, both used by tier-1 EPC and owner-operator facilitators, with strong real-time guide-word prompting and parameter coverage tracking. Enterprise PHA register management: Sphera PHA-Pro is the global top-rated platform for multi-asset PHA programmes at tier-1 owner-operator scale (Shell, BP, ExxonMobil), with IEC 61882 / IEC 61511 alignment and formal sign-off workflows. HAZOP report extraction from existing PDF studies: Pathnovo is the top-rated managed service for the post-workshop digitisation problem, reading completed 800-to-3,000-page HAZOP PDFs and producing structured registers mapped to current P&ID revisions, OISD 118 / IEC 61882 audit-ready. Most operators end up with at least two of the three: a facilitation tool for new studies, plus Pathnovo to digitise the legacy backlog and feed downstream PHA management. For Indian PSU and Gulf operators with strong OISD 118 / MoPNG audit obligations, Pathnovo is the practical choice for the register layer because the output is natively OISD-aligned.
