France seizes Russian shadow fleet tanker in Indian Ocean, vows to combat illicit oil trade “wherever it may be in the world”

France has seized an oil tanker suspected of belonging to Russia’s shadow fleet after intercepting it more than 450 nautical miles south of Réunion in the Indian Ocean, French President Emmanuel Macron announced on 12 October.

The seizure targets a network Russia relies on to keep oil revenues flowing despite Western sanctions imposed over its full-scale invasion of Ukraine. The shadow fleet allows Moscow to continue exporting oil and funding its war in Ukraine. 

The French Navy boarded the DF Peak over suspicions that it was sailing under a false flag and involved in illegal fuel transportation, Macron said. French forces escorted the vessel to an anchorage near Réunion for further checks as part of a judicial investigation. 

La France est déterminée à lutter contre la flotte fantôme, partout dans le monde.

What is Russia’s shadow fleet?

Russia’s shadow fleet consists of oil tankers used to keep Russian oil and petroleum exports moving despite Western sanctions imposed after Moscow launched its full-scale invasion of Ukraine in 2022.

The vessels often operate through opaque ownership structures, change names or flags, and use registration practices that make it harder to establish who controls them and where their cargo originates. These methods help Russia maintain oil revenue while limiting the impact of sanctions and restrictions on shipping and insurance. 

The fleet also raises safety and environmental concerns. Many of the vessels are older tankers operating with unclear insurance coverage or limited oversight, increasing the risk of accidents and oil spills.

DF Peak previously sailed under different name

The DF Peak was previously named Kaliningrad and sailed under the flag of Benin. It has been subject to US, UK, and EU sanctions since 2024, according to Reuters. Ukrainian military intelligence has also linked the tanker to Russian crude oil transportation and the shipping company Sovcomflot. 

The tanker was last tracked near Madagascar on 12 October after departing from Venezuela, according to shipping data cited by Reuters. French authorities said the vessel would be taken to Réunion for a closer examination of its registration and activities. 

Russia condemns seizure

Russia’s embassy in France condemned the seizure, calling it a violation of international law and describing the operation as “piracy,” according to Russian state media cited by Reuters. The embassy said France had not notified Moscow about the seizure and that it was checking whether Russian citizens were among the crew. 

The seizure is part of wider European efforts to enforce sanctions against Russia’s oil exports and target vessels suspected of using false flags. France has seized at least five Russian-linked tankers since 2024, Reuters reported.
