Three steps from deliverable
to traceable finding register.
Owner’s-engineer AI reviews for oil & gas deliverables — traceable findings, comment registers and human-supervised escalation in hours. Here is exactly what happens inside the black box.
Drop it in. Get findings back.
You drop the deliverable.
Upload your P&ID, isometric drawing, equipment datasheet, HAZOP register, or spec section. Native formats supported: PDF, DWG, XLS, structured exports. Redacted documents work fine.
SpecSense runs codified CEng checks.
The discipline classifier identifies the document type and routes it to the correct check sequence. Each check runs in order — the same sequence an Owner's Engineer would follow, encoded into logic.
You get traceable findings with human sign-off.
A Chartered Engineer triages severity, discards false positives, and signs the comment register. You receive a PDF/CSV register with code citations, drawing locations, and recommended actions. Hours, not weeks.
The review pipeline, stage by stage.
Every deliverable passes through the same codified sequence. No stages are skipped. No stages run without the prior stage’s output as input.
OCR / parse
The document is extracted into structured text, tables, and geometry. For DWG files, drawing entities are parsed. For PDFs, layout and table structure are preserved. Handwritten annotations are flagged.
Discipline classifier
The document is classified: P&ID, isometric, equipment datasheet, HAZOP register, line list, spec section, or other. The classifier selects the appropriate check library and cross-reference set.
Check sequence
The discipline-specific check sequence runs. Checks are ordered: prerequisite data checks first, then primary engineering checks, then cross-document consistency checks. The order is codified, not arbitrary.
Code citation
Every flagged item is matched to a code clause. ASME B31.3, ASME B16.5, API 520, API 521, IEC 61511, ASME BPVC VIII-1, NACE MR0175 — the relevant edition and clause number. No generic references.
Severity scoring
Candidate findings are scored Major, Minor, or Info based on safety consequence, code compliance status, and rework cost. Scoring is discipline-calibrated, not generic.
CEng review
A Chartered Engineer reviews every candidate finding. False positives are discarded. Major findings are annotated with escalation recommendations. The engineer signs the register.
Export
You receive a PDF finding register, a CSV comment register in your template format, and an audit trail log. Every finding links back to the pipeline stage that generated it.
Codified checks per input type.
Different deliverable types get different check sequences. A P&ID review is not the same workflow as a HAZOP register review.
P&ID
Piping & Instrumentation Diagrams
- Line class consistency vs. line list
- Spec breaks — correct class transitions at battery limits
- Valve types against service fluid and pressure class
- Relief valve presence and discharge routing
- Instrument tagging format against ISA 5.1
- Utilities cross-connections flagged
- Shutdown logic consistency against cause-and-effect matrix
Isometric
Piping Isometrics
- Flange class vs. design pressure at service temperature
- Wall thickness vs. design pressure + corrosion allowance
- Thermal expansion provisions — loops, offsets, guides
- Support spacing against allowable span tables
- Material call-out against line class specification
- Weld joint factor applied to seamless vs. ERW pipe
- PWHT requirements triggered by material and thickness
Datasheet
Equipment Datasheets
- Design pressure and temperature vs. vessel code margin
- Material selection for service fluid, H₂S content, and temperature
- NACE MR0175 compliance for sour service
- Nozzle schedules — size, rating, and position completeness
- Nameplate data consistency vs. process datasheet
- Inspection category and test pressure derivation
HAZOP
HAZOP Registers
- Action closeout status — open actions with no assigned owner
- Recommendations with no cause-and-effect matrix reference
- SIL targets recorded but not referenced in SIL calculation
- Consequence descriptions without mitigation safeguard
- Deviations missing credible initiating cause
- Independent Protection Layers (IPLs) credited without validation
What a finding looks like.
Every finding is traceable — code clause, drawing location, severity, and recommended action. No vague commentary. No ambiguity about what needs to change.
