Verification method

Every verdict hasa chain of custody.

Barrier Intelligence connects each conclusion back to the source document, spatial assumption, physical scenario and detector response that produced it. The result can be checked, challenged and signed.

The golden path

Six controlled steps. No unexplained jump from input to claim.

The three stages, Reconstruct, Sweep and Verdict, expand into six controlled steps. The system accelerates the engineering work while keeping the judgement visible and reviewable.

Technical evidence chain connecting source documents, process plant physics and a traceable finding register.

Establish the plant basis

Define the unit, assessment boundary, target coverage and the Fire & Gas credit already being claimed.

Audit the inputs

Parse the HAZOP, LOPA, philosophy, register, mapping report and drawings with page-level provenance.

Reconstruct the spatial case

Align leak nodes, detector coordinates, obstructions and voting logic to the 3D plant model.

Sweep credible physics

Test releases across wind direction, speed, stability and geometry-driven dispersion behaviour.

Apply the credit wall

Allow only physical performance to earn credit; evidence confidence can demote a verdict but never promote it.

Issue the assurance package

Export the register, overlays, gaps, remediation priorities, method and limitations for engineer sign-off.

Three kinds of truth

The method resolves the basis, the physics and the credit.

Each stage answers a different question before the barrier verdict can be trusted.

Engineering documents resolved into a structured and source-linked data model.
01 / Basis

Reconstruct the claim

Turn scenarios, assumptions and detector data into a structured basis without losing the document, page or revision behind each fact.

A process module surrounded by a physical coverage sweep and active detector.
02 / Physics

Sweep credible reality

Test release behaviour through the plant geometry, detector field and full relevant wind space instead of relying on nominal reach.

Interlocking engineering structures forming a controlled barrier credit gate.
03 / Credit

Issue the credit verdict

Let demonstrated detector response determine the state, then retain limitations, evidence quality and engineering authority around it.

Two coordinated engines

One understands the basis. The other tests the plant.

Neither document extraction nor simulation is treated as sufficient on its own.

01 · Document Intelligence

Structure the engineering claim before testing it.

The document engine finds scenarios, detector assumptions, voting claims and risk-reduction credit without obscuring the original source.

  • ADeterministic parsing and source-page citations
  • BConflict, omission and confidence flags
  • CHuman review before a scenario is admitted

02 · Spatial and physics

Test whether the hardware earns that claim.

The spatial engine resolves the relationship between the release, plant geometry, detector field and time-to-detect.

  • AScenario and full wind-space sweep
  • BObstruction, shadowing and channelling
  • CPhysical detector votes bound to scenarios

Solver selection

Assure3D uses the fastest method that can still defend the decision; the qualified solver always owns the final verdict.

The credit wall

Automation can organise the evidence. It cannot award itself assurance credit.

Barrier Intelligence separates calculation from engineering authority so the final claim stays honest.

01 / Physical vote

Physics decides

Only demonstrated detector response can earn a credited state.

02 / Evidence quality

Confidence can only demote

Weak or conflicting evidence moves a result toward caution, never optimism.

03 / Governance

An engineer signs

The method, limitations and final disposition remain visible to the qualified reviewer.
