Before you charter, finance, insure or do business with a vessel, you need its compliance standing. Marifest screens every ship in the registry against public sanctions and inspection data — here’s how, and how to check any vessel by IMO.
Four public data sources, combined into one transparent read-out per vessel — so before you charter, finance, insure or do business with a ship, you can see its compliance standing and screen any vessel by its IMO number.
Each ship — and its owner, operator and manager — is checked against the consolidated designated-party lists from the US Treasury (OFAC SDN), the EU, the UN Security Council and the UK (OFSI). We resolve owner names to catch the shadow-fleet trick of hiding a sanctioned beneficial owner behind a fresh single-ship company.
PSC inspections under the Paris and Tokyo MoUs produce a public record of deficiencies and detentions. A vessel detained in the last 12–36 months, or with repeated deficiencies, carries elevated operational and reputational risk — and we factor it into the score.
The MoUs rank flag registries white / grey / black by their fleets’ inspection performance. The flag a ship flies is a compliance signal in itself: a black-list flag plus an opaque owner is a classic high-risk pattern.
We combine sanctions matches, owner/operator screening, PSC detentions, flag band and vessel age into a transparent 0–100 risk score — with the evidence shown, not a black box. Free visitors see that a vessel has been screened; members see the full result and set alerts.
How do I check if a ship is sanctioned?
Screen the vessel by its IMO number against the consolidated OFAC (US), EU, UN and UK sanctions lists, and check whether its registered owner or operator is a designated entity. Marifest cross-references every ship in the registry against these public lists and surfaces a clear sanctions status and risk score for members.
What is Port State Control (PSC)?
Port State Control is the inspection of foreign ships in national ports to verify compliance with international safety, security and environmental rules. Regional agreements such as the Paris MoU and Tokyo MoU publish vessel detention records, which are a key compliance signal — a recent detention raises a vessel’s risk profile.
What is a flag state white / grey / black list?
The Paris and Tokyo MoUs rank flag states by the inspection and detention performance of the ships registered under them. White-list flags perform well; grey and black-list flags have higher detention rates and warrant extra due diligence.
What is an IMO number?
An IMO number is a unique seven-digit identifier permanently assigned to a ship’s hull by the International Maritime Organization. Unlike a name, flag or owner — all of which can change — the IMO number stays with the vessel for life, which is why it is the reliable key for compliance screening.
