Maritime Chokepoint & Reroute Risk Analyzer
Evaluate geopolitical threats across critical maritime choke points (Bab el-Mandeb, Hormuz, Malacca). Model voyage rerouting via the Cape of Good Hope, bunker fuel deltas, carbon emissions, and war-risk premiums.

Strategic Context: Red Sea & Global Trade Lanes
The Bab el-Mandeb strait connects the Gulf of Aden to the Red Sea and Suez Canal, handling roughly 12% of global seaborne trade and 30% of container traffic. When armed conflicts or military strikes occur in or adjacent to Yemen, missile and drone threats against commercial vessels force shipping liners to evaluate the trade-off between paying exorbitant war risk insurance rates or incurring a 10 to 14-day detour around the Cape of Good Hope.
This engine quantifies the naval routing decision by combining hydrodynamic speed-power laws (fuel consumption scaling as the cube of speed), bunker pricing, canal toll avoidance, insurance underwriters' Hull & Machinery (H&M) war risk quotes, and fleet capacity absorption.
Frequently Asked Questions
How is the Cape of Good Hope fuel and time delta calculated?
Direct passage from Shanghai to Rotterdam via Suez spans approximately 10,500 nautical miles, compared to 14,300 nautical miles via the Cape of Good Hope (an additional ~3,800 NM). At typical cruising speeds of 15.5 knots, this adds approximately 10 to 13 sailing days each way, inflating voyage fuel requirements by 800 to 1,200 metric tons depending on vessel displacement.
What is War Risk Insurance and why does it spike?
War risk insurance is typically quoted as a percentage of the vessel's insured hull value for a 7-day transit window through Joint War Committee (JWC) listed areas. During heightened strikes or US/coalition retaliatory military operations, premiums can jump from 0.05% to over 1.0% of ship value. For a $130M container vessel, a 0.75% premium equals $975,000 for a single passage, rendering the Suez Canal route more expensive than sailing 3,800 NM around Africa.
How does this affect supply chains and container freight rates?
Diverting ships around Africa absorbs 6% to 9% of global container ship capacity because vessels remain at sea longer. The resulting shortage of ship arrivals in Europe and North America triggers equipment imbalances, port congestion, and spot rate spikes (e.g. SCFI, FBX indexes).
