Geopolitical Transit & War-Risk Modeling

Black Sea Maritime Corridor & War-Risk Transit Simulator

Compare hypothetical route and premium assumptions. Scores, map waypoints and capacity fixtures are authored educational scenarios, not live navigation, coverage or safety assessments.

Keep historical context separate from scenario assumptions

The UN Black Sea Grain Initiative began in July 2022 and expired on 17 July 2023. Selecting a truce here does not establish that a current agreement exists, or restore navigation rights or security guarantees.

The Joint War Committee lists areas requiring notice to underwriters. It does not set premium rates: those are negotiated by brokers and underwriters. This page’s rate range, discounts and exclusion labels are authored fixtures. Its map, coordinates, cover labels and mine animation are illustrations, not a passage plan or a mine-clearance report.

IMO’s Black Sea and Sea of Azov advice provides maritime-security context, including floating-mine concerns. It does not validate these waypoints, threat scores, escort claims or selected capacity figures.

Separate arithmetic from maritime risk evidence

Does a lower scenario score mean a ship is safe or insurable? No. This tool applies fixed multipliers and category rules. Use it to understand sensitivity to assumptions, while keeping real navigation warnings, insurance terms and current agreements separate.

Worked premium example

A $45 million scenario asset at a 0.75% base rate, multiplied by the hypothetical truce factor 0.55, gives 0.4125%. The code rounds the rate to 0.41% before calculating cost, so the display is $184,500 rather than $185,625. The selected Panamax value combines hull and cargo; it is not a separately verified hull-policy insured value.

Trace what changes each output

Duration is the route’s fixed nautical-mile distance divided by selected knots. It omits loading, queues, weather and port restrictions; individual waypoint hours are independent fixtures. The threat score starts at 18, 36, 68 or 88 by framework; mine-countermeasure selection subtracts 12 or adds 20, direct routing outside the truce adds 22, and Danube routing subtracts 8. The result is clipped to 5–98, not an incident probability.

Capacity is fixed at 6.4, 4.2, 1.8 or 0.3 million tons per month by framework, capped at 2.4 for the Danube. Vessel size, speed and premium do not calculate capacity. Premium multipliers are 0.55, 0.90, 1.65 and 2.4, with a minimum effective rate of 0.10%. Dispatch animates a hypothetical route; it neither sends a convoy nor queries current maritime data.

Primary sources and their limits

The UN FAQ establishes the original initiative’s dates. The historical committee circular dated 25 April 2023 states that application to individual contracts is negotiated; it is not a current listed-area check. IMO supplies maritime-security advice. None endorses this tool’s rates, coordinates, numerical capacity or protective-cover assumptions.
