Shanghai to Britain’s busiest container port at Felixstowe — the East Asia–to–UK trunk lane exposed to Bab-el-Mandeb diversions and Suez transit risk.
As of 2026-08-23, ArcNautical scores the 9,994 nm Shanghai → Felixstowe corridor 80/100 — High risk, and avoiding the Red Sea via the Cape of Good Hope adds about 2,693 nm / 8 days over the Suez routing. Signals: Joint War Committee, ReCAAP/IMB piracy, ACLED/GDELT conflict, marine weather.

High risk. The Red Sea / Bab-el-Mandeb war-risk corridor is the dominant exposure on this lane. The Cape of Good Hope diversion remains the conservative routing assumption.
ArcNautical's voyage engine composites eleven independent intelligence signals along the actual sea route, then weights each by how much it is driving risk on this corridor right now. Bar width = current severity of that signal; the percentage = its share of the composite score.
Listed-area intersections come from the Joint War Committee (JWC) hull-war zones, tested against the route geometry — not a country list. These are the areas underwriters load war-risk premium for.
This route runs 12% of its distance through sanctioned waters. A leg inside a sanctioned EEZ is where AIS-gap, dark-STS and shadow-fleet activity concentrate — the geography compliance teams have to be able to defend.
Route transits 3 sanctioned EEZ(s): Yemen [OFAC, UNSC] (5%), Libya [UNSC] (4%), Federal Republic of Somalia [OFAC, UNSC] (3%). 17 other EEZ(s): Indonesia (8%), Vietnam (6%), Taiwan (5%), Sri Lanka (4%), China (4%), Egypt (4%), Andaman and Nicobar (4%), Eritrea (4%), Maldives (4%), Halaib Triangle (3%), France (2%), Malaysia (2%), United Kingdom (1%), Morocco (0%), Djibouti (0%), Singapore (0%), Algeria (0%)

The route crosses Southern Red Sea and Gulf of Aden and Bab el-Mandeb and Arabian Sea and Indian Ocean high-risk waters, and runs 12% of its distance through sanctioned waters.
Taiwan Strait, Singapore Strait, Malacca Strait, Bab el-Mandeb, Suez Canal, Strait of Gibraltar. Total distance 9,994 nautical miles, roughly 30 days at 14 knots.
Routing via the Suez Canal is about 30 days at 14 knots. Diverting around the Cape of Good Hope to avoid the Red Sea / Bab-el-Mandeb adds roughly 2,693 nautical miles and 8 extra days — about 38 days end to end.
