Vessel Sanctions, AIS Anomaly & Counterparty Due Diligence Tool

Screen a proposed charter, cargo, insurance or commercial transaction against user-supplied vessel facts. Trace the vessel's identity, sanctions-list checks, ownership, AIS behavior, STS history and counterparties into a documented investigation pathway. No live official sanctions feed is connected: this tool cannot establish sanctions clearance.

Fast vessel and transaction screen: 12 inputsEnter findings from the sources you checked. “No match reported” means only that the user reports a check; it does not mean this tool checked a sanctions database. Leave unknown matters as unknown.

Investigation-grade reviewEvaluate the vessel, jurisdiction, ownership chain, voyage anomalies, counterparties and documents separately. Enter event-level evidence in the registers below. Red decision gates override numerical comfort.

Legal boundary: A screening index is not a probability of sanctions violation, legal finding, official list check, authorization, or permission to transact. Determine applicable U.S., UK, EU, UN and other restrictions, ownership/control rules, licences, transaction nexus and competent-authority obligations separately. Do not enter sensitive personal identifiers unnecessary to review.

Ownership & Control Chain

Record direct and indirect links, including entities exercising control without a majority equity stake. Percentages are review data, not an automated legal ownership determination.

Use	Holder / entity	Relationship	Direct stake %	Reported listing result	Control rights	Evidence	Screen reference	Review

Counterparty & Payment Register

Review charterers, owners, managers, cargo principals, brokers, banks and insurers independently. A possible name match requires investigation before it is treated as a designation.

Use	Entity	Role	Jurisdiction	Reported list screen	KYC / ownership	Payment / service concern	Evidence reference	Review

AIS, Flag, STS & Port Event Register

Record dates, location context and evidence for each AIS gap, suspected spoofing event, flag switch, STS transfer or unusual port call. Gaps and STS operations are not automatically misconduct.

Use	Date	Event	Area / port	Duration h	Explanation	Corroboration	Source	Review

Evidence, Screening & Close-out Register

Capture the actual database and document reference, reviewed state, reviewer and next action. Avoid recording confidential personal data unless strictly required by your internal policy.
