The operating system for cylinder integrity.
Every cylinder. Every inspection. Cryptographically proven.
Vulcan-7 creates a cryptographically verifiable digital history for every cylinder — identity, capture, AI assessment, inspector review, integrity score, digital passport, and requalification decision, in one system of record. Digital passports and compliance reporting are outputs, not the product.
Why the industry needs this
No digital traceability
Millions of cylinders in circulation have no machine-readable identity and no digital history at all.
Paper records resist audit
Test logs live in binders and spreadsheets. Reconstructing a cylinder's history for a regulator can take days.
Overaged assets stay in service
Without enforced requalification intervals, cylinders past their due date keep being filled and delivered.
Evidence can't be verified
An inspection photo or certificate is only as trustworthy as the person handing it over. Nothing proves it wasn't altered.
Ownership changes constantly
Cylinders move between manufacturer, filler, hub, and customer. Custody breaks, and accountability breaks with it.
Vulcan-7 creates a cryptographically verifiable digital history for every cylinder.
Every identity, capture, AI assessment, inspector decision, custody transfer, and requalification is hash-chained and signed. Anyone holding the asset — or auditing it years later — can prove what happened without trusting the party that recorded it.
From capture to compliance
- 1
Cylinder
The physical asset to be inspected.
- 2
IdentifyQR / Data Matrix / OCR
Unique cylinder identification and asset registration.
- 3
CapturePhotos / video
Standardised visual capture from multiple angles.
- 4
AI Assessment
AI models analyse images for corrosion, damage, deformation, and other defects.
- 5
Inspector Review
Human expert reviews AI findings, adds notes, and confirms inspection results.
- 6
Integrity Score
Calibrated score reflecting the overall integrity and risk level of the cylinder.
- 7
Digital Passport
A cryptographically signed record of the cylinder's identity, inspection history, and integrity score.
- 8
Requalification Decision
Data-driven pass, monitor, or reject — enabling safe return to service and regulatory compliance.
Every cylinder. Every inspection. Cryptographically proven.
Trust. Traceability. Compliance.
Built for every stakeholder in the chain
Defensible evidence trails
Replace paper logs with regulator-ready documentation in one click. Every inspection is cryptographically signed, timestamped, and exportable as a tamper-proof PDF.
Cradle-to-grave traceability
Every handover from factory to supplier to owner is hash-signed into the audit chain. Prove provenance in a post-incident review, not just claim it.
Calibrated AI integrity scores
No black-box guesses. Penalty-based AIS scoring with cluster deduplication, calibrated to EN standards. Human label loops for continuous improvement.
From capture to compliance
Multi-angle & 360° video inspection
Capture 6-angle photos or a full 360° video. Calibrated scoring detects corrosion, dents, bulges, ovality, and composite damage — fiber exposure, UV chalking, delamination, impact dents, and cycle fatigue.
Digital Cylinder Passport (DCP)
A single source of truth per asset. Map QR codes, RFID, barcodes, and OCR reads to one unified passport. Identity Confidence Score (ICS) gates final approval: below 80 triggers provisional status and requires a human cosigner.
WebAuthn-signed audit chain
Inspector and cosigner assertions are cryptographically bound to every inspection. Export a .vulcan-bundle for offline verification — no server required to prove authenticity.
Composite Integrity Assessment (CIAF)
Weighted 5-factor scoring for fiber-wound and fully wrapped cylinders. Fiber matrix, impact damage, UV degradation, cycle fatigue, and coverage. Tenant-tunable thresholds with automatic escalation to review queues.
One platform, the whole cylinder estate
Vulcan-7 resolves construction type and gas service first, then dispatches the correct scoring engine, checklist, and requalification interval for that asset — metal assets never get composite logic, and composite assets never get asked for UT wall thickness.

The capture device is interchangeable
Vulcan-7 treats capture as a pluggable layer. Whatever the hub already owns can feed the same evidence pipeline — and the device, firmware, and pairing time are stamped onto every evidence row in the audit chain.
Phone & tablet
Standard iOS/Android browser capture with guided angles, 30 fps Data Matrix burst decoding, and offline queueing.
Industrial & ATEX cameras
Intrinsically safe camera adapters for hazardous fill halls, paired over the capture-source registry.
UT thickness gauges
Wall-thickness readings ingested as first-class evidence rows for metallic assets.
Scales & tare rigs
Tare-drift detection cross-checked against stamped and registry values.
Laser & 3D scanners
Geometry capture for dent, bulge, and ovality assessment on high-value assets.
File import & manual entry
Legacy photo sets and paper results can be back-filled with explicit provenance flags.
The full operating system for cylinder integrity
Device-agnostic capture layer
Phone, tablet, industrial camera, ATEX-rated camera, UT thickness gauge, scale, laser scanner and PAUT adapters. The device, firmware, and pairing time are stamped onto every evidence row.
Marking transcription engine
Reads neck rings, composite valve bosses, moulded labels, and shoulder stamps — serial, manufacturer, standard code, tare, water capacity, test pressure, and requalification dates — with per-character confidence gating and registry cross-checks.
QR, Data Matrix & dot-peen
Continuous 30 fps burst decoding with auto-ROI cropping for laser-marked industrial codes. Any registered asset resolves instantly to its passport, last verdict, and re-inspection due state.
Requalification & condemnation
Standard-correct intervals per construction and gas service, overdue detection, quarantine on severity or chain break, and a full condemnation workflow with cutting evidence, GPS verification, and scrap certificates.
Regulator-grade lifecycle record
Asset condition and certification eligibility reported separately, evidence cards, view-classifier tables, explainable trust scoring, assembly context for MEGCs, and QR links that auto-verify the audit chain.
Fleet & manufacturer intelligence
Manufacturer × construction × gas feature datasets, overdue-for-inspection counts, peer-cohort benchmarking, AIS inflation monitoring, and exportable CSV for regulators and OEM quality teams.
Multi-tenant hubs & roles
Inspection hubs, manufacturers, fleet owners, and regulators operate in isolated tenants with row-level security, specialty-based hub directory, time-boxed regulator grants, and co-signing separation of duties.
QA harness & operating modes
Labelled evaluation datasets, precision/recall per damage class, dual-model cross-checks, and shadow → assisted → autonomous graduation gates before AI decisions carry weight.
Validated in the field, not just on paper
Composite LPG cylinders registered
Live count across pilot fleets — grows as each new composite asset is registered.
Data Matrix identification
Laser-marked Data Matrix codes on composite valve bosses decode reliably in the field, resolving straight to the asset's Digital Cylinder Passport.
Inspections recorded
Every one hash-chained into a verifiable audit trail.
Checklists and intervals mapped to the code that governs the asset
Requalification intervals, inspection checklists, and rejection criteria are selected from the combination of construction type and gas service, with tenant-level thresholds for regional regulator variations.
