The Ship That Should Not Have Been There
The Caroline Bezengi is a 274-metre Suezmax tanker built in 2001. It is part of Russia's so-called shadow fleet: older, poorly maintained ships that sail under obscure flags, lack Western insurance, and exist primarily to move sanctioned Russian crude to buyers who cannot be seen purchasing it openly. The vessel was sanctioned by the UK, EU, Ukraine, Canada, and Switzerland for carrying oil that finances Russia's war. It was nominally registered under Cameroon's flag but was de-listed from that registry in June 2026, one of 39 vessels struck off at the same time.

In April 2026 it loaded at Novorossiysk on Russia's Black Sea coast, transited the Suez Canal in late May, and was heading for Asia with a cargo of close to one million barrels of crude when things went badly wrong off Yemen.

:TIMELINE
🛢️⚠️🌊
2026-04-01 | The Caroline Bezengi loads Russian crude at Novorossiysk port and transits the Suez Canal bound for Asia with close to one million barrels aboard.
2026-06-08 | An explosion is reported aboard the vessel off Yemen. No party claims responsibility. A Ukrainian mine attack is suspected but has not been confirmed.
2026-06-11 | The tanker transmits its last public AIS tracking signal and goes dark, drifting off the Yemeni coast without Western insurance or emergency cover.
2026-07-26 | Satellite imagery confirms the Caroline Bezengi grounded near the Hallaniyat Islands, Oman. The initial slick covers approximately 20 sq km.
2026-08-04 | Greenpeace satellite analysis places the slick at 600 sq km. It has been expanding rapidly as the damaged hull continues to leak crude.
2026-08-07 | PAX environmental expert Wim Zwijnenburg estimates the spill at 800 sq km, with the sheen now 90 km long, nearly double its length of a week earlier.
2026-08-10 | Oman issues its first public disclosure confirming a slick of 390 sq km within 7 km of the coast and announces engineering interventions to address the hull.

:NOTE
What is at stake. The Hallaniyat Islands sit inside a nature reserve established by royal decree in 2025. It is home to endangered Arabian Sea humpback whales, one of the world's smallest and most isolated whale populations, plus Socotra cormorants, nesting green and loggerhead turtles, and coral reefs. Taimur Al Said of Oman's Environment Authority says oil is already killing turtles and birds and damaging coral. The monsoon season is hampering cleanup, and forecasters warn the slick could drif

The situation surrounding the Caroline Bezengi is yet another alarming example of the serious environmental risks posed by Russia's so-called shadow fleet.

:NOTE
How cleanup works at this scale. A spill of 800 sq km cannot be contained by booms alone. The response requires dispersant aircraft to spray across the affected area, booms and skimmer vessels to collect surface oil before it reaches the coast or sinks to the seafloor, and controlled burning of any thicker accumulations offshore. Oman is coordinating aerial surveillance, diver teams, and satellite environmental modelling. Officials are also planning to transfer the crude cargo from the stricken

:NOTE
The shadow fleet problem is bigger than one ship. Russia currently operates an estimated 400 to 600 shadow fleet vessels carrying sanctioned oil around the world. Many are ageing, uninsured, and uninspected. The Caroline Bezengi is not the first such ship to suffer a catastrophic failure at sea, and environmental experts warn it will not be the last. The International Maritime Organization has no current mechanism to compel inspections of sanctioned vessels, and the gap in liability means no sin
