Manual vetting is slow, fragmented, and incomplete

A single vessel vetting requires a compliance analyst to check five or more separate databases, manually trace corporate ownership through opaque jurisdictions, and cross-reference every entity against multiple sanctions lists. Most teams spend 3 to 6 hours per vessel and still miss things.

3-6 hrs

Per vessel, manually

Equasis for PSC detentions. OFAC for SDN matches. EU consolidated list. UN Security Council resolutions. Company registries for ownership. Each database has a different interface, different data format, different update schedule. Analysts toggle between tabs and copy-paste into spreadsheets.

Ownership chains hide risk

A vessel registered in Panama, owned by a Marshall Islands shell company, controlled by a Cyprus holding, with a beneficial owner in a sanctioned jurisdiction. Standard screening checks the vessel name and stops. The real risk sits two or three layers up the corporate chain.

Stale data creates exposure

Sanctions lists update on different cycles. OFAC may update its SDN list while you are still referencing last week's download. A vessel cleared yesterday can be designated today. Without continuous monitoring, your compliance posture degrades the moment you close the report.

One search. Complete dossier.

Enter a vessel name, IMO number, or MMSI. ArcNautical runs the full vetting pipeline automatically and returns a structured dossier within seconds.

1

Identify the vessel

Search by vessel name, IMO number, or MMSI. ArcNautical resolves the vessel identity and pulls basic particulars: flag state, class society, year built, DWT, vessel type, and last known position.

2

Resolve the ownership chain

Query the GLEIF LEI registry for the registered owner. Walk the corporate parent chain: direct parent, ultimate parent, beneficial owners. Cross-reference against the OpenOwnership BODS dataset. Map every entity to its registration jurisdiction.

3

Screen every entity for sanctions

Every entity in the chain — vessel, registered owner, parent companies, beneficial owners, operators, managers — is screened against three sanctions lists simultaneously: OFAC SDN (US), UN Security Council consolidated list, and the OpenSanctions maritime dataset covering 3,701 vessels and 3,362 companies.

4

Score vessel risk factors

Pull PSC detention records from Paris MOU and Tokyo MOU. Score flag state performance against the Paris MOU white/grey/black list. Assess vessel age. Calculate corporate opacity based on jurisdiction transparency, number of layers, and GLEIF coverage. Weight all factors into a composite vetting score.

5

Generate audit-ready PDF

Export a timestamped vessel dossier PDF that documents every data source queried, every entity screened, and every risk factor scored. The report includes methodology notes for regulatory review and is designed to satisfy KYV requirements for marine insurance, trade finance, and port state compliance.

Built on authoritative sources, not scraped summaries

Every data point in a vessel dossier traces back to a primary source. ArcNautical queries these registries directly and caches results with defined TTLs so you always get current data without hammering rate-limited APIs.

Vessel vetting for every link in the maritime chain

Different roles need different depth from a vessel dossier. ArcNautical serves them all from the same underlying data pipeline.

Compliance teams

Screen vessels before charter, cargo booking, or port call. Get structured sanctions results that satisfy OFAC guidance on due diligence for the maritime industry. Export audit-ready PDFs for regulatory review.

Marine insurers and P&I clubs

Assess vessel risk before binding coverage. The vetting score combines detention history, flag performance, vessel age, and ownership opacity into a single number. Ownership chain sanctions screening catches risks that vessel-level checks miss.

Maritime law firms

Due diligence for vessel acquisitions, charter party disputes, and sanctions advisory. The ownership chain resolution provides a documented trail from vessel to ultimate beneficial owner with jurisdiction mapping at each level.

Trade finance banks

Screen vessels carrying financed cargo against sanctions lists before issuing letters of credit. The combined ownership-plus-vessel screening satisfies KYC/AML requirements specific to maritime trade finance workflows.

Stop toggling between five databases

Enter a vessel name or IMO number and get a complete dossier — ownership chain, sanctions screening, detention history, flag risk, and opacity score — in seconds.
