Shadow Fleet AI

When a shadow fleet tanker goes dark, our agents don’t stop looking.

Six European boardings of sanctioned tankers since Sep 2025. Belgium seized Ethera in the North Sea (Feb 28). France boarded Tagor off Brittany (Jun 1). Russia sent a Su-35S to block Estonia's Jaguar intercept in the Baltic (May 14). Both sides are escalating.

The CLC/Fund Convention compensation chain requires a P&I club in the liability sequence. When the next grounding happens in these corridors, there is no club to call. No insurer on the hook. The legal backstop does not exist.

EVENTIN (IMO 9308065) has sat seized off Rugen since January 2025. OFAC SDN listed. No active IACS class. No western P&I. One vessel. One corridor. A preview of the liability structure that governs all 652 tracked Russian shadow tankers transiting Baltic waters.

641 of 652 tracked shadow tankers carry no IACS class cover. Of the 18 that transited the Danish Straits last month: 0 carry western P&I. Three HELCOM corridors (Danish Straits, Gulf of Finland, Kattegat) see this traffic weekly. The gap is systemic, not exceptional.

Russian Arctic crude from Kola Bay travels on Aframax shadow tankers. MT Tagor loaded at Umba FSU in April 2026, declared destination Cameroon. France seized her in the Atlantic. The cargo origin does not change with the flag. The loading record at Kola Bay is permanent.

EU's April 23 services ban on Russian tankers (insurance, flagging, banking, shipping) is not happening, EU diplomats told Euronews June 4. Envoy O'Sullivan: energy prices leave 'no appetite' for the measure. Sanctioned tankers keep loading. Vessel count next.

367 tankers in IMO GISIS carry false registrations (Apr 4 2026). One in six Hormuz transits flew a fake flag (Lloyd's List, May 2026). 10 Basrah-cluster tankers spoofed Iraqi anchorage positions: $800M in crude, zero paper trail a PSC can trust. IMO GISIS, LL1157281, Windward.

OFAC May 2026 "Economic Fury" sweep: 19 designations targeting vessels, intermediaries, and traders in one action. Timed against Hormuz pressure, where ~20% of global oil transits. When nodes travel together, screening must too. Source: OFAC Recent Actions.

A risk score would have surfaced this as elevated. That tells you nothing you can defend to a regulator. The evidence chain: AIS gap, satellite pass, port record, P&I lapse, IACS flag. That is what you put in the file. That is what Shadow Fleet AI produces.

[Shadow Fleet AI @shadowfleet_ai]

VLCC, IMO 9487621. AIS dark 11 days, Apr 14-25. Reactivated 38 nm off Kharg Island (laden draft confirmed by satellite, Apr 19). P&I lapsed Feb 2026. IACS class withdrawn Jan 2026. Five signals. One identification.

[Shadow Fleet AI @shadowfleet_ai]

The question an underwriter now faces: did this vessel go dark for war risk, or to move sanctioned Iranian crude? A risk score cannot answer that. The signals can: STS location, P&I lapse date, flag-state re-registry, IACS class withdrawal. One chain per vessel.

[Shadow Fleet AI @shadowfleet_ai]

Dark vessel activity at the Strait of Hormuz surged ~600% between April 19 and May 3. Shadow fleet tankers now account for ~80% of Hormuz transits, up from 10-15% pre-war (Lloyd's List Intelligence). The compliance problem just inverted.

[Shadow Fleet AI @shadowfleet_ai]

Maritime Mutual Insurance (NZ) was sanctioned by the UK on Feb 24. At the time it covered ~1-in-6 Western-sanctioned shadow tankers. Blunt AIS-gap screens now flag most Hormuz traffic. Each false positive is a legal exposure, not just an inconvenience.

[Shadow Fleet AI @shadowfleet_ai]

Four names. Five flags. Five sanctions programs. Tagor still transited until France stopped it. Sporadic boardings do not change the calculus. Flag-state enforcement is the missing layer. Our tracker covers the full population, not just the one ship that gets boarded.

[Shadow Fleet AI @shadowfleet_ai]

France boarded MT Tagor (IMO 9282481) on 2026-05-31, ~400 nm west of Brittany. UK support via HMS Somerset. The ship was presenting a false Madagascar registration. Cargo: Russian Arctic crude from Kola Bay. Five sanctions programs, none of them recent.

[Shadow Fleet AI @shadowfleet_ai]

Per Lloyd's List (2026-06-01), at least five other fraudulently flagged ships were transiting European waters while France detained Tagor. That is the context. The flag states issuing false registrations operate without consequence.
