EU Expands Operation IRINI to Target Cameroonian-Flagged Shadow-Fleet Tankers

Escalating Enforcement of the Shadow Fleet
On 8 June 2026 the European Union broadened the mandate of its Mediterranean naval mission, Operation IRINI, authorising it to stop, board, detain and inspect vessels suspected of belonging to Russia’s “shadow fleet”. Within weeks IRINI boarded three tankers—Nelsa, Oneiroi and Sandhya—identified as operating under fraudulent Cameroonian registration. The French navy seized the tanker Deliver on 25 June near Sicily, despite its removal from Cameroon’s registry.
Background: Fraudulent Flag Use and the Shadow Fleet
Russia has long used older tankers lacking Western insurance or safety certification to evade sanctions, registering them under flags of convenience. Cameroon’s ship registry emerged as a major conduit, prompting the United Arab Emirates in 2024 to bar Cameroon-flagged ships lacking top-tier safety certification. By mid-2026 Cameroon confirmed that its registry had been misused to conceal ownership and cargo of Russian oil shipments.

- Russian authorities – publicly condemned the EU’s expanded enforcement.
- French, Belgian, British and Swedish navies – have seized nine ships since the start of 2026, five of them bearing Cameroonian flags.

Official Statements & Responses
Cameroon’s transport ministry said the country is “cooperating with international authorities and organisations to enforce maritime rules, protect the credibility of its naval registry, and fight against irregular registrations.” The EU highlighted the expanded IRINI mandate as essential to prevent sanction evasion and to safeguard maritime safety.
Criticism & Opposition
Moscow condemned the EU’s move as an unlawful interference with legitimate shipping activities.
Why It Matters
The crackdown aims to cut revenue streams that fund Russia’s war effort while addressing safety risks posed by un-certified vessels that could endanger crews and the marine environment.
