Maritime Sanctions Data
How traceable is the ownership of the sanctioned fleet?
Data as of 2026-06-21 · source: ArcNautical vessel screening (GLEIF ownership-chain resolution over the OFAC-anchored screened set)
Corporate ownership of the sanctioned-vessel fleet is largely untraceable in the public LEI register: of 1,862 screened vessels (anchored on the OFAC-designated fleet), only 1.1% resolve even a corporate parent in GLEIF and 67.7% have no GLEIF-resolved owner at all (data as of 2026-06-21).
| Public ownership-chain traceability (GLEIF) | vessels | % of total | |
|---|---|---|---|
| No owner resolved in GLEIF | 1,260 | 67.7% | |
| Registered owner in GLEIF, no corporate parent | 581 | 31.2% | |
| Corporate parent resolved (GLEIF) | 21 | 1.1% | |
| Total | 1,862 | 100% |
Methodology
- Each vessel is placed in its DEEPEST stage of GLEIF resolution: no owner resolved in the GLEIF LEI register; a registered owner identified (a GLEIF legal entity) but with no onward corporate parent; or a corporate parent resolved in the GLEIF chain. This measures traceability via the GLEIF Global LEI Index specifically — a vessel with no GLEIF match may still have a registered owner in other records (a flag registry or commercial database), so "no GLEIF-resolved owner" means not traceable in the public LEI register, not necessarily ownerless.
- GLEIF resolves the corporate parent / consolidating entity, NOT the AML ultimate beneficial owner (the natural person who ultimately owns or controls the entity). So "corporate parent resolved" is still not a verified beneficial owner — and for the sanctioned fleet you usually cannot get even that far. GLEIF parent-chain coverage is sparse generally, so this measures public-record traceability, not necessarily true corporate structure.
- Distinct from the ownership-opacity dataset (which scores opacity risk LOW / MEDIUM / HIGH): this one measures how far the ownership can be RESOLVED in public records, not how risky a resolved owner is.

FAQ
Can you verify who owns a sanctioned vessel?
As of 2026-06-21, only 1.1% of 1,862 screened vessels resolve even a corporate parent in the GLEIF register; 67.7% have no GLEIF-resolved owner at all, and 31.2% resolve a registered owner in GLEIF with no onward corporate parent. Public LEI records rarely establish the ultimate beneficial owner for this fleet.
Does GLEIF show the ultimate beneficial owner?
No. GLEIF resolves the corporate parent / consolidating entity, not the AML ultimate beneficial owner (a natural person). This dataset measures how far the ownership chain can be followed in public records — for the sanctioned fleet, usually not even to a corporate parent.
