See which tankers get sanctioned next.

Deadlight scores every tanker running Russia's Baltic oil routes on the behavior that came before past Western sanctions designations. Compliance teams see the risk weeks before the listing.

Tested on weeks the model never saw.

We froze the model on history through April 2026, then scored 46 later weeks of traffic and checked who got sanctioned.

71 days, median

Historical out-of-time test, 46 weekly snapshots. A live forward test began 13 October 2026, and results will be published as tankers it flagged are designated or cleared.

Built for teams that can't afford to learn about a listing from the news.

Banks and trade finance

Flag vessels behind a letter of credit or cargo loan before they become a sanctions problem.

Insurers and P&I clubs

Spot hulls drifting into shadow-fleet patterns while you can still price or decline the risk.

Traders and due diligence firms

Screen counterparties and charters against forward risk, not only today's lists.

How it works

Deadlight follows tankers through the Danish straits using public ship-tracking data, and checks every one against official US, UK, EU and allied sanctions lists.

Each day it scores vessels on traits like age, size, where they load, going dark, and changes of name or flag. The model's weights were fixed before testing, so the results are not tuned after the fact.

What a pilot delivers

1
Monthly ranked watchlistEvery scored tanker, highest risk first.
2
The evidence behind each scorePort calls, voyages and identity changes, in plain language.
3
Cargo and ownership contextEstimated capacity, and owners where a government list names them.
4
A running scorecardPast calls checked against actual designations.

Every call is timestamped. Each watchlist is anchored to a public ledger the day it's issued, so anyone can verify a tanker was flagged before it was designated.
