FLAG‑CHANGE PATTERNS AMONG SANCTIONED RUSSIAN‑LINKED VESSELS
Project Type: Dashboard
Overview
This dashboard examines the historical flag‑change behaviour of 545 Russian‑linked vessels designated by the UK FCDO as of mid‑January 2026. It highlights re‑registration frequency, common flag pathways, and long‑tail flag usage — offering insight into identity‑shifting patterns and potential sanctions‑evasion risk. The dashboard is designed to support behavioural profiling and enforcement prioritisation.
Methodology
This dashboard was built using vessel data sourced from OpenSanctions, which aggregates multiple international sanctions datasets. Because the FCDO list alone did not capture all Russian‑linked vessels under sanction, using OpenSanctions ensured fuller coverage by incorporating additional sources such as EU datasets.
After extracting the combined list of 545 vessels, the data was cleaned and standardised in Power Query, including normalising flag codes, aligning registry names, and removing duplicates. Historical flag‑registration records were then reconstructed to create complete flag‑change sequences for each vessel.
From this, analytical fields such as total flag‑change counts, registry frequencies, and grouped low‑frequency registries were generated. The cleaned dataset was modelled in Power BI, where visuals were designed to highlight re‑registration cycles, identity‑shifting behaviour, and the prominence of permissive registries.
The analysis interprets flag‑change frequency as a behavioural risk indicator, particularly when combined with AIS gaps, ownership changes, or route anomalies, supporting investigative prioritisation in sanctions and maritime‑risk contexts.
Flag‑Change Behaviour Across Sanctioned Russian Vessels FCDO Sanctions List — January 2026

Observed Patterns
​
Most vessels show 3–5 historical flag changes, with a clear peak at 4. This reflects sustained re‑registration activity across their operational histories, a pattern commonly associated with identity-shifting tactics (e.g., frequent re-registration to obscure vessel provenance or ownership) and evasion‑linked behaviour.
​
The concentration of re‑registrations among Gabon, the Marshall Islands, Panama and Liberia highlights consistent pathways used by sanctioned vessels to reposition themselves.

Key Insights
​
-
Russia appears as the largest category because the dataset consists exclusively of Russian‑linked vessels; its size reflects the scope of the sanctions list rather than re‑registration behaviour.
-
The prominence of Liberia, Panama, Marshall Islands, and Gabon suggests these registries function as accessible reflagging options for sanctioned vessels.
-
Their repeated appearance in multi‑flag sequences indicates lower barriers to re‑registration and potential exploitation of permissive regulatory environments.
-
The “Other” category comprises 52 low‑frequency registries, potentially reflecting opportunistic reflagging during identity‑shifting cycles.
