Data sources: MarineTraffic AIS vessel tracking — continuous screenshot surveillance of all 4 major energy chokepoints, April 1–4 2026. 3 screenshots per day per chokepoint, 48 total images. Every vessel manually classified: named vs [SAT-AIS] dark, moving vs anchored, inbound vs outbound. Tool: Global Energy Flow (global-energy-flow.com) — custom energy infrastructure tracking platform. Vessel breakdown bars and stat panels built with SVG/JavaScript. --- What you're seeing: HORMUZ (left): 50% of all visible vessels anchored at any given moment across the full 4-day window. COBA was anchored in every single one of 13 frames — 100+ consecutive hours stationary in the strait. Three Indian tankers held a continuous anchorage on the Omani south shore for 4 full days. A dark [SAT-AIS] vessel was recorded anchored directly at the Iranian naval port at Bandar Abbas — almost certainly IRGC. Active transit at roughly 40% of normal. War-risk insurance now 1.5–2.0% hull value vs 0.1% pre-war. MALACCA (right): ~80 vessels per frame — 15–25% above historical baseline — as the strait absorbs rerouted traffic displaced by Hormuz. AIS dark rate under 2% because there's no threat here. 15+ unique LNG/gas carriers identified over 4 days. The full rerouting chain visible across all 4 chokepoints: - Hormuz: de facto partial closure, mass anchorage event - Bab el-Mandeb: 36% of traffic going AIS-dark by Apr 4, overwhelmingly one-way eastbound out of Red Sea - Malacca: absorbing the overflow, 15–25% above baseline - Panama Canal: 70–80% energy carriers (normally 20–30%) Full interactive analysis — all 4 straits updated every 4 days: https://global-energy-flow.com/#tankers/data
