Turkish authorities recently reported a dramatic incident involving two oil tankers linked to Russia’s “shadow fleet” in the Black Sea. Both ships, which are under international sanctions, caught fire near the Bosporus Strait, prompting a swift rescue operation.
The first vessel, the Gambia-flagged Kairos, exploded and caught fire about 28 nautical miles off Turkey’s Kocaeli province. It was making its way from Egypt to the Russian port of Novorossiysk, carrying no cargo. Shortly after, the second tanker, the Virat, also experienced trouble, about 35 nautical miles from the coast.
Turkish maritime authorities suggested the explosion on the Kairos was due to an “external impact,” but they haven’t disclosed details about the source of the attack. This raises uncertainties; officials are investigating whether it was caused by drifting naval mines, which have caused similar incidents in the Black Sea in the past.
Due to these events, maritime authorities are on high alert to ensure the safety of ship traffic in the Bosporus area.
Sanctions Background
The crews onboard the ships, 25 from the Kairos and 20 from the Virat, were rescued by coast guard units. Both ships have been on sanctions lists since the Russian invasion of Ukraine in 2022. They are part of a fleet used to circumvent restrictions on Russian crude oil. According to OpenSanctions, the Virat was sanctioned by the U.S. in January 2025, followed by similar actions from the EU, UK, Canada, and others. The Kairos faced EU sanctions in July 2025.
Experts emphasize that this shadow fleet plays a crucial role in enabling Russia to sustain significant revenue amidst tough international sanctions. They operate under various flags and use intricate schemes to obscure ownership, posing both an economic challenge and a potential environmental threat.
Interestingly, historical context reveals that the Virat, built in 2018, has previously sailed under several flags, including those of Barbados and Panama, while the Kairos, built in 2002, has a similar diverse history.
Environmental Concerns
The incidents have triggered alarm over the environmental safety of the Black Sea, an area already seen as high-risk due to years of conflict and leftover munitions. Experts point out that the presence of oil tankers in these turbulent waters raises the stakes for potential ecological disasters.
Recent discussions on social media highlight public concern about the safety of maritime operations in the Black Sea. Many are calling for stricter regulations and better monitoring to prevent further incidents.
In light of this ongoing situation, it is crucial for authorities to remain vigilant. With the backdrop of sanctions and ongoing tensions in the region, the safety and environmental sustainability of maritime operations should be a top priority.
