Defence intercepts Russian shadow fleet vessel in the North Sea

In the night from Saturday to Sunday, the oil tanker Ethera, part of Russia’s shadow fleet, was boarded in Belgian waters. The vessel was sailing under a false flag and is listed under European Union sanctions.

“These are serious indications of deliberate deception and possible sanctions evasion. When such signs emerge in our exclusive economic zone, we take action,” said Minister of Defence Theo Francken.

Enforcing sanctions and tightening the screws on the war economy

The shadow fleet consists largely of ageing tankers operating under changing or fraudulent flags, manipulating their AIS signals, or hiding behind complex ownership structures. These tactics are used to circumvent international sanctions and keep oil revenues out of sight — revenues that directly fund the war against Ukraine.

“Our government has made it clear that we intend to stop vessels from the shadow fleet from transiting our waters. This operation puts that commitment into practice. We are enforcing European sanctions, safeguarding our North Sea from abuse and increasing pressure on the financial flows that fuel Russia’s war against Ukraine. The shadow fleet poses a security risk. Belgium will not allow its maritime space to be used to undermine international law,” Minister of Defence Theo Francken stated.

Close operational cooperation

The successful security operation was the result of close cooperation between the Navy, the Air Force and the Special Operations Forces. Belgium also received French air support during the mission, in the form of two NH-90 helicopters.

“As maritime neighbours, we face the same threats. That is why we work closely together to strengthen security in the North Sea,” added Minister of Defence Theo Francken.

The boarding operation was carried out in close coordination with the Federal Public Prosecutor’s Office, the West Flanders Public Prosecutor’s Office, the Directorate-General for Shipping and the Maritime Police. At the Flemish level, the Agency for Maritime Services and Coast (MDK) was involved, with the Pilotage service providing nautical advice. The Maritime Rescue and Coordination Centre (MRCC) played a supporting role in risk assessment and safety.

“This operation shows that our maritime services stand ready around the clock. The cooperation between Defence and the MDK Agency was professional and efficient. The safety of shipping and the protection of our critical offshore infrastructure remain absolute priorities for Flanders,” said Flemish Minister for Ports Annick De Ridder.
