The only service that reads completed HAZOP study PDFs and produces a structured action register mapped to the current P&ID revision. Competitors like SALUS and Kairos Technology do HAZOP facilitation; they run the workshop. Pathnovo solves the next problem: the 800–3,000 page PDF produced by the workshop is unqueryable, actions live in Excel, trip loops reference deleted P&ID tags, and audit preparation takes weeks. Pathnovo extracts every node, deviation, consequence, safeguard, recommendation, action, responsibility, and due date, then maps each action to the current P&ID so superseded nodes are flagged before they become audit findings.
Scanned PDFs, digital-born PDFs, Word documents, Excel worksheets, legacy template variants from DNV, Lloyd's, Bureau Veritas, TÜV SÜD, independent consultancies, and in-house teams. Multi-language studies supported. No template configuration required.
Node, deviation, parameter, guide word, cause, consequence, frequency, severity, risk rank, existing safeguards, recommended action, action type, action owner, due date, status. Every column the facilitator recorded, extracted and structured.
Every HAZOP action mapped to the specific P&ID tag, line, or equipment reference on the current revision. Superseded nodes (deleted tags, renamed lines, removed equipment in later revisions) flagged for HSE review. No orphaned actions.
Actions categorised by risk priority (critical, high, medium, low) based on consequence and likelihood ratings. Compatible with IEC 61882, ISO 31000, and OISD 118 risk matrices. Custom project risk matrices loaded per engagement.
Output structured in OISD 118-compliant format for Indian O&G regulatory submission. IEC 61882 format for international audit. Client-specific formats accommodated.
Once extracted, the register becomes the single source of truth for action tracking. Status, evidence document links, closure approvers, and audit history maintained over the plant lifecycle.
Every extracted action links back to its source page and paragraph in the original HAZOP PDF. Click any register row to see the originating HAZOP worksheet line. Chief Controller / MoPNG / HSE auditor-ready.
A completed HAZOP PDF uploaded by 9am is returned as a structured register within 48 hours. Volume pricing for multi-unit turnaround campaigns.

Any format: scanned PDFs at any DPI, digital-born PDFs, Word documents, Excel worksheets, database exports. Legacy studies from any HAZOP consultancy (DNV, Lloyd's Register, Bureau Veritas, TÜV SÜD, KBC, Intertek), from independent facilitators, and from in-house HSE teams. The format of the HAZOP worksheet does not matter; the system adapts to the columns present in each study.
SALUS and Kairos are HAZOP facilitation tools; they support the workshop itself, suggesting deviations and recording actions live. They do not extract data from completed, paper / PDF / Word HAZOP studies after the fact. Pathnovo starts where SALUS and Kairos leave off: the 800–3,000 page study document produced post-workshop, which historically sits in Excel and becomes unqueryable. Pathnovo reads that document and produces a structured register mapped to the current P&ID.
A HAZOP action is associated with a specific P&ID node: a piece of equipment, a line, a tag. Between the HAZOP and today the P&ID has probably gone through multiple revisions. Some tags have been renamed. Some equipment has been replaced. Some lines have been deleted. An action that closes on a superseded node is not actually closed. Pathnovo maps every HAZOP action against the current P&ID revision so superseded nodes are identified, re-evaluation is triggered, and closure evidence is valid.
Yes. The register output is structured in OISD 118 format for Indian MoPNG audit submission. Column set, risk matrix, action typology, and closure evidence requirements all match OISD 118. IEC 61882 and ISO 31000 formats are also supported.
99%+ accuracy on action capture (not missing any recommendation), 98%+ accuracy on field-level extraction (deviation, consequence, safeguard, action text, owner, due date). Accuracy is validated per study with a sample review before full release. The audit-trail link from register row to source page is 100%; every claim is traceable.
Yes. Native multi-language extraction for Hindi (Devanagari), Arabic, Farsi, Japanese, Korean, Mandarin, and Cyrillic scripts. Most Indian PSU HAZOPs are English, but regional plant studies sometimes carry Hindi / regional-language notes in safeguards and recommendations; these are preserved and translated where requested.
The extracted register is delivered in client-native format: Excel, CSV, JSON, or direct API feed into SAP QM, Intelex, Sphera, Cority, or custom HSE systems. Client-specific column mappings and risk matrices are configured at project kick-off.
HAZOP register extraction is included on every paid tier of the credit-based pricing model. A typical 800-3,000 page study draws from your monthly credit pool (HAZOP / spec pages = 2 credits each), so a single-unit study fits comfortably inside Starter (1,000 credits/month) or Professional (5,000 credits/month). Multi-unit operators digitising large HAZOP archives move to Scale or Enterprise with bulk one-time data-room ingestion priced separately. Indian PSU rate-card compatibility available. See our pricing page for full plan details.
After any plant change (MoC, Management of Change) the HAZOP needs re-validation. Pathnovo maintains the parent register, accepts the re-HAZOP study, and produces a delta register showing which actions are confirmed, which are new, which are superseded, and which need re-evaluation.

Every process plant on earth has completed HAZOP study PDFs. None of them are queryable. Actions are tracked in Excel, disconnected from the P&ID. SALUS and Kairos solve the workshop side (live HAZOP facilitation) but not the post-workshop extraction side. SAP QM and Intelex track action closure but cannot read HAZOP PDFs. Pathnovo is the only vendor globally extracting structured action registers from completed HAZOP study PDFs with P&ID node mapping. The buyer pain is universal, the competition is near-zero, and the regulatory driver (OISD 118, IEC 61882, MoPNG audits) guarantees demand.
The largest HAZOP studies (FCCU, CDU-VDU, hydrocracker, steam cracker, LNG train) routinely run 2,000–3,000 pages covering 200–500 nodes. Pathnovo parallelises extraction across pages, maintains node-level context (parameter, guide word, deviation header inherited by all child causes), and applies consistency checks across the full document. A 3,000-page study is typically returned within 48 hours.
99%+ on action-capture completeness (no missed recommendations), 98%+ on individual field extraction (deviation text, consequence, safeguard list, action text, owner, date). Every field links back to its source page in the original PDF for independent audit. Accuracy is benchmarked per study on a sample review before the full deliverable is released.
Yes. When the P&ID is revised (Rev A → Rev B → Rev C), each HAZOP action's target node is re-evaluated against the latest revision. Deleted tags, renamed equipment, and removed lines are flagged. New equipment introduced in the revision that lacks HAZOP coverage is also flagged. The output is a gap register telling the HSE team exactly which actions need re-evaluation and where new HAZOP coverage is missing.
Facilitation tools (SALUS, Kairos) output structured session data directly from the workshop. For these, Pathnovo is not needed; the data is already structured. But every operator has a legacy archive of pre-tool HAZOP studies in Word or PDF form, and every HAZOP consultancy still produces a post-workshop report PDF for client sign-off. That is the archive Pathnovo digitises. The two approaches are complementary, not competitive: use SALUS / Kairos going forward, use Pathnovo to digitise the backlog.
