Russia’s Shadow Fleet and the Rise of African Flags of Convenience
Since the full‑scale invasion of Ukraine in 2022, Western governments have imposed sweeping sanctions on Russian energy exports. In response, Moscow has turned to a clandestine network of aging tankers—commonly referred to as the “shadow fleet”—to keep its oil flowing to global markets. A growing body of research shows that many of these vessels now sail under African flags, exploiting weak registration oversight to conceal ownership and evade enforcement.
How the Shadow Fleet Operates
The shadow fleet consists of oil tankers and other merchant ships that frequently change names, flags, and ownership structures. According to the Center for Research on Energy and Clean Air (CREA), these ships use opaque corporate layers, disable automatic identification systems (AIS), and rely on ship‑to‑ship transfers to mask the origin of their cargo.
- CREA estimates that the shadow fleet moved about 50 % of Russia’s seaborne oil in March 2024.
- Approximately 591 vessels comprise the network, capable of transporting up to 4.1 million barrels of oil per day.
- The operation generates billions of dollars in annual revenue, helping finance Russia’s war economy.
These tactics are not new, but the scale and sophistication have increased as sanctions tighten.
African Registries as a Tool for Obfuscation
Research from the Robert Lansing Institute, cited by DefenseWeb, highlights that African shipping registries often lack robust verification mechanisms for vessel ownership and operator background. This makes them attractive to actors seeking to hide sanctioned assets.
Key findings include:
- More than half of documented “false flag” cases—where a ship flies a flag that does not reflect its true benefactor—occur within African jurisdictions.
- The Lansing Institute describes the trend as evidence that the shadow fleet is evolving from a temporary workaround into a “stable and institutionalized logistics network.”
- Countries such as Benin, Comoros, Gambia, Guinea, and Sierra Leone have reported sharp rises in registered tonnage linked to Russian‑linked vessels.
Once a vessel is registered under an African flag, enforcement becomes considerably more complex. As the Lansing Institute notes, “Once vessels operate under the legal protection of another country’s registry, enforcement becomes far more complex.”
Impact, Evidence, and International Response
Several recent reports quantify the extent of African‑flagged involvement:
- Maritimecrimes.com reports that the European Union, the United Kingdom, and the United States blacklisted 110 Comorian‑flagged ships in 2025 for transporting oil that supports Russia’s war effort.
- The Institute for Security Studies (ISS) found that Cameroon’s shipping registry grew by 126 % year‑on‑year, suggesting a surge in new registrations likely tied to sanctions evasion.
- Malawi, which does not maintain an international shipping register, recorded eight incidents of fraudulent use of its flag in the past year and has appealed to Interpol and the International Maritime Organization (IMO) for investigation.
These developments have drawn scrutiny from Western governments and maritime regulators. Authorities are increasingly calling for stronger due‑diligence requirements, improved information sharing among registries, and targeted sanctions against entities that facilitate flag‑of‑convenience abuse.
Why This Matters
The use of African flags is more than a technical loophole; it undermines the effectiveness of sanctions designed to curb aggression. By allowing Russian oil to continue reaching global markets, the shadow fleet prolongs the financial capacity to sustain military operations. Experts from CREA, the Lansing Institute, and ISS agree that closing these regulatory gaps is essential to preserving the integrity of the international sanctions regime.
Continued monitoring, transparent registry practices, and coordinated enforcement will be key to reducing the shadow fleet’s ability to evade accountability. As the situation evolves, the international community’s response will test the resilience of maritime governance in the face of sophisticated evasion tactics.
