FEED and concept select
Test detector philosophy, layout concepts and equipment spacing before decisions become expensive to reverse.
Applications
Keep the barrier crediblethrough every plant change.
A Fire & Gas layout is not a one-time drawing. Assure3D helps design teams, operators and assurance leaders test the barrier at the decisions where confidence matters most.
Across the lifecycle
Use the same evidence logic from first layout to operating reality.
Each application answers a different engineering question without changing the definition of proof.
Detailed design
Challenge proposed locations against credible releases and issue a defensible coverage basis for review.
Commissioning and startup
Compare the installed detector register and as-built model to the credit assumed in the safety case.
Management of change
Re-test coverage after equipment, enclosure, ventilation, inventory or detector changes alter the physical case.
Periodic or incident reassessment
Reconstruct why a barrier should have responded, what changed and where assurance needs to be restored.
Decision moments
Apply the physics when the plant or its claim changes.
The same verification logic supports design choice, controlled change and restored operating assurance. The five lifecycle points group into these three decision moments.
01 / Design
Design and FEED
Compare philosophies and detector layouts while there is still time to change equipment spacing, coverage intent or hardware.
02 / Change
Management of change
Re-test the physical case when equipment, enclosure, ventilation, inventory or detector positions move.
03 / Reassess
Restore assurance
Resolve what changed, which detector positions still count and the smallest action that makes the barrier credible again.
Built for the decision makers
One physical truth, expressed for each engineering role.
The same scenario evidence supports design action, operating assurance and accountable sign-off.
Process safety consultants
Move from document reconciliation and sampled mapping to a reviewable, scenario-bound assurance package.
More time for judgementOperators and asset teams
Know which claimed barriers remain credible, which are at risk and the smallest action that restores confidence.
Portfolio-ready prioritiesF&G design engineers
Compare detector locations and voting concepts before issue, installation and handover.
Earlier design feedbackFor project teams
Resolve the hard coverage questions before handover.
Use physics-grounded evidence to compare layouts, document design decisions and focus specialist review where it changes the outcome.
- 01Layout option comparison against the same scenario set
- 02Minimum-hardware optimisation without lowering the target
- 03Traceable design basis for client review
For operating assets
Know whether today's plant still matches yesterday's claim.
Reconcile as-built conditions and current documents, then direct limited capital toward the gaps that genuinely control the barrier.
- 01Post-MOC and ageing-asset reassessment
- 02Risk-ranked blind zones and timing failures
- 03Remediation sequenced by assurance value
Choose a decision point
Start where uncertainty is already slowing a decision or weakening a claim.
A focused pilot can be scoped around one unit, one layout decision or one assurance question.
