Russian tanker leaking oil off Oman coast, threatening environmental disaster

A Russian tanker, the Caroline Bezengi, ran aground off the coast of Oman on June 8, potentially causing an environmental disaster akin to the 1989 Exxon Valdez spill. The ship, which is part of Russia's shadow fleet, was carrying millions of gallons of oil and had six cargo holds filled with oil when it ran aground. The crew abandoned ship following an unexplained explosion.

Satellite images revealed an oil leak on June 30, with an estimated 200,000 gallons spilled by August 7. With five of its six cargo holds filled with oil, the tanker could have been carrying up to 40 million gallons. Oman has been responsible for containing the spill and preventing a disaster, deploying aircraft, divers, and specialized personnel to assess the situation.

However, the tanker's owner has shown no public response, and its insurance status is unclear, leaving Oman to bear the responsibility for cleanup efforts. Ambrey, a British maritime security and salvage company, is en route to the tanker, but challenging weather conditions pose a significant hurdle. The full extent of the leak may not be known until the complex operation to remove the remaining oil is completed.

The Gulf of Oman and the Arabian Sea are home to protected marine life, including sea turtles, sharks, and rare humpback whales. The area surrounding the tanker was recently designated a marine reserve. Russia relies on aging tankers in its shadow fleet, often operated under opaque ownership structures and with little or no insurance, raising questions about liability for salvage and cleanup costs.

Amos warns that even a swift response can only recover a fraction of the oil released, with typical response efforts recovering only about 20% of the spilled oil. The potential cost of the disaster is enormous, with the Exxon Valdez cleanup estimated at $2.1 billion, or $5.8 billion in today's dollars.
