Catastrophic Exposure Lives in Geometry — Not Probability.
HarborArc maps where routine failures become unrecoverable, and which port assets carry systemic consequence long before an incident makes it visible.
Ports manage probability. Catastrophic geometry is left uncharted.
Most frameworks assume competence, redundancy, and procedures keep failure inside a recoverable envelope. But some locations are structurally unforgiving. One propulsion loss in the wrong segment can force an unrecoverable drift sequence.
- Failure is routine. Equipment trips and human misjudgement occur every day.
- Geometry is unforgiving. Stopping distance, drift and response windows collapse faster than confidence recognises.
- Consequence is structural. The difference between a contained incident and national disruption is where failure occurs, not who was on the bridge.
“If a vessel loses control here, under realistic conditions, does the outcome remain bounded — or become systemic?” HarborArc answers that before an investigation does.
Structural Exposure Mapping — magnitude before likelihood.
Layer 1 defines where catastrophic consequence exists inside port geometry. No probability modelling. No behavioural analysis. Only structural truth.
Phase 1 – Identify Consequence Carriers
Determine which bridges, terminals, waterfronts, and logistics nodes produce systemic disruption if struck or closed.
Phase 2 – Map Unrecoverable Arcs
Overlay stopping distance, turning arcs, drift vectors, tug windows, and time-to-impact to reveal segments where recovery is impossible.
Phase 3 – Trace Escalation Pathways
Transit → Failure → Drift → Impact → Structural Failure → Closure → Systemic Effect.
Phase 4 – Assign Consequence Bands
Apply consistent, non-probabilistic consequence classifications that only change when the structural pathway changes.
What HarborArc produces.
HarborArc is not a workshop concept. It produces concrete artefacts that boards, regulators and pilots can act on and defend.

If you have a bridge, terminal, or transit segment that has “always been fine”, HarborArc will determine whether its geometry agrees.
