What's Going On With the Oil Spill Near Oman?

Oman is trying to stop an oil spill covering almost 400 square kilometres off its southern coast. The oil is now within about 7 kilometres of land, according to the Oman Environment Authority on August 10, 2026 (Al Jazeera).
The spill is centred around the Hallaniyat islands, where Oman's leader, Sultan Haitham bin Tariq Al Said, created a marine protected area the year before. A protected area is a zone set aside to keep wildlife and habitats safe. Greenpeace and PAX told AFP that the damaged tanker, called the Caroline Bezengi, was carrying about one million barrels of crude oil headed for Asia.
The Caroline Bezengi picked up its oil cargo at a Russian port called Novorossiysk on the Black Sea in April and travelled through the Suez Canal at the end of May. According to an AFP investigation, the ship had been stuck since early June near Oman's al-Qibliyyah Island after an explosion let water into parts of the ship. Video footage obtained by Reuters appears to show the tanker still sitting just off al-Qibliyyah, about 25 nautical miles south of Oman's coast (Maritime Executive).
The Caroline Bezengi is believed to be part of Russia's "shadow fleet" — a loose group of ships used to sell Russian oil despite Western sanctions. Sanctions are penalties that countries use to restrict trade with a specific country or business. In this case, Western nations restricted purchases of Russian oil to pressure Moscow over its war in Ukraine. The tanker is sanctioned by the European Union, Ukraine, the United Kingdom, Canada, and Switzerland. Shipping records list its owner as Rentoor Shipmanagement, a company based in Shanghai that could not be reached for comment (Al-Monitor).
The spill has been tracked by satellites for weeks. On July 17, Reuters reported that the Caroline Bezengi was leaking oil near Oman, using satellite images and expert analysis. By July 31, Reuters reported the spill was spreading. Greenpeace estimated the slick at about 600 square kilometres the week before August 10, based on satellite image analysis. Satellite imagery reviewed by the Associated Press confirmed crude oil leaking from the grounded tanker (ABC News). The difference between Greenpeace's 600 km² estimate and Oman's current figure of nearly 400 km² could come from different ways of measuring, different satellite timing, or the oil naturally spreading and thinning over time.
The broader context here is the risk that the shadow fleet creates for countries along some of the world's busiest shipping routes. These ships often operate without standard insurance or normal safety oversight. When something goes wrong, it is very hard to figure out who is responsible, because ownership is hidden behind layers of shell companies and vague registration arrangements. The Caroline Bezengi's path, from a sanctioned Russian oil terminal through the Suez Canal to a stranding off Oman's coast, shows how far that risk can reach.
For Oman, the spill affects both nature and the local economy. The Hallaniyat marine reserve was created to protect wildlife in an area where fishing and coastal tourism matter to people's livelihoods. A spill reaching shore in a protected zone would test Oman's ability to contain it and could raise hard questions about who pays for the damage. The vessel's sanctioned status and its hard-to-trace ownership make those questions even more complicated. Rentoor Shipmanagement's silence, while not an answer in itself, shows how difficult it is to pursue cleanup costs from a company embedded in the shadow-fleet system.
The incident also raises questions about early warning. The explosion on the Caroline Bezengi was reported about a month before the spill was publicly documented through satellite images. That gap between the ship's failure and the international response shows how little coastal countries can know about ships passing through their waters when those ships are not following normal tracking and reporting rules.
What remains unresolved is the full environmental outcome. The oil is close to shore, it is in a protected island area, and the tanker is believed to still be carrying a large volume of crude. All of this points to a long and difficult cleanup. The tanker remains stuck, and no one has independently measured how much oil is still leaking beyond what satellites can see.
