• Open a vessel profile for sanctions dates by authority, sources, programs, and external trackers (MarineTraffic, VesselFinder, etc.).
• Use year filters to see ships designated in a specific year (e.g., vessels sanctioned in 2024).
• Looking for a particular authority? Visit: OFAC, OFSI, EU, Canada, Australia, New Zealand.
• On each profile you’ll find links to create a Google Alert for the exact IMO and quick photo search for due-diligence packs.

• Shipowners/beneficial owners, operators, technical managers, charterers, and brokers screening fleets and fixtures.
• Insurers/P&I clubs, reinsurers, classification societies, flag registries, port agents, bunker suppliers assessing services eligibility under sanctions and the G7/EU price-cap regime.
• Commodity traders & banks/FFIs (secondary-sanctions risk; financing, payments, letters of credit).
• Port State Control, terminals, pilots verifying arrivals, documentation, and risk flags.
• Investigative journalists & NGOs tracking the “shadow fleet” and deceptive shipping practices.

• AIS manipulation (prolonged gaps, spoofed GNSS, impossible tracks) and unexplained STС transfers in high-risk zones (e.g., Laconian Gulf, mid-Atlantic, Persian Gulf).
• Identity laundering: rapid name/flag/class/owner changes, recycled MMSI, older tonnage with opaque ownership or uninsured/alternative P&I.
• Above-cap Russian-origin oil moved with poor documentation/attestations under the G7/EU price-cap services rules.
• Routing anomalies, frequent calls at unsanctioned but high-risk transshipment hubs, or vessels tied to sanctioned groups and facilitators.

• Blocking sanctions (SDN/asset freeze): U.S. persons must block property; dealings are prohibited; majority-owned entities are also blocked.
• Price-cap services bans: denial of insurance, brokering, financing, flagging, classification, or other key maritime services if oil is above the cap (see the Price Cap Coalition guidance).
• Secondary-sanctions risk: foreign financial institutions face designation risk for significant support to Russia’s war economy (e.g., U.S. EO 14024 §11).
• Operational disruption: port denials, detention, cargo discharge conditions, potential forfeiture/seizure in some jurisdictions.

We mirror official lists published by OFAC, OFSI, EU Council, Canada (SEMA), Australia (DFAT), and New Zealand (MFAT) and aggregate them into a single vessel index. Our pipeline runs daily; each entry shows the first designation date we derive across sources. The “As of” note reflects the latest run.

• Sanction timeline: badges for each authority with the date we have recorded.
• Programs & notes: reason/authority program (e.g., RUSSIA-EO14024; Russia (Sanctions) Regulations 2019), plus investigative remarks.
• Source snapshot: official IDs or list entries to help you verify at the origin.
• External trackers & images: quick links for traffic history and document packs.

• See the full sanctioned vessels timeline across all authorities.
• Browse by authority: U.S. (OFAC) · U.K. (OFSI) · EU · Canada · Australia · New Zealand.
• Looking for one ship? Use your browser search (⌘/Ctrl-F) on this page, or open the vessel profile and follow the “Web search” / “Create Google Alert” buttons.
