The Omani government deployed aircraft, divers, and specialized personnel to assess the vessel and prepare mitigation efforts. Ambrey, a British maritime security and salvage company, was hired to coordinate the salvage operation of the Caroline Bezengi. Ambrey personnel boarded the Caroline Bezengi with assistance from the Omani air force to assess its condition. The salvage operation involves vessels, aircraft, and over 100 metric tons of equipment.

Ed Wollaston, Global Response Director at Ambrey, described the operational difficulties. "This is an extremely challenging situation, compounded by adverse weather conditions associated with the Khareef monsoon." Wollaston said. Hanen Keskes, Regional Campaigns Lead at Greenpeace MENA, noted the difficulty of remediation once contamination spreads.

"It can make the cleanup significantly more complex than containment at sea." Keskes said. John Amos, CEO of SkyTruth, offered a stark assessment of the environmental impact. "Once the oil hits the water, you've already lost." Amos said.

The United Nations International Maritime Organization stated it is closely monitoring the leakage. The Omani government instructed citizens to avoid fishing in affected areas and to report unusual odors and oil sightings. The International Oil Pollution Compensation Funds determined it would not be involved in the cleanup because the incident likely resulted from an act of war.

Timeline

The Hallaniyat Archipelago, where the spill is concentrated, was designated a marine reserve in 2025. The Caroline Bezengi departed from Novorossiysk, Russia, in May 2026. The Caroline Bezengi traveled through the Suez Canal in late May 2026.

The crew of the Caroline Bezengi reported an explosion or unidentified incident on board in early June 2026. The crew abandoned the Caroline Bezengi after the incident. The oil tanker Caroline Bezengi ran aground off the coast of Oman. The Caroline Bezengi was carrying an estimated 800,000 barrels of oil when it ran aground. The Caroline Bezengi grounded on a rocky outcropping near Al-Qibliyyah Island (also referred to as Qabiliyah Island).

What's New

On August 12, 2026, the Environment Authority of Oman reported that oil pollution from the grounded vessel Caroline Bezengi had affected some beaches in the Ras Madrakah area, with an expected affected coastal stretch of up to 40 kilometers in length, according to a statement issued by the authority. Omani authorities stated that approximately 40 kilometers of coastline in the Ras Madrakah area were affected by oil pollution. The oil spill from the Caroline Bezengi has reached the coastline of Ras Madrakah in Oman.

Ambrey personnel boarded the Caroline Bezengi with assistance from the Omani air force to assess its condition. The Caroline Bezengi departed from Novorossiysk, Russia, in May 2026. The Hallaniyat Archipelago, where the spill is concentrated, was designated a marine reserve in 2025. The Caroline Bezengi was carrying approximately 1 million barrels of Russian crude. Russian Federation; capital Moscow; located in Europe & Central Asia; classified by the World Bank as a high income economy.

How Sources Differ

Reports differ on the cargo capacity of the vessel. One source states the Caroline Bezengi was carrying approximately 1 million barrels of Russian crude, while shipping data analysis indicates the Caroline Bezengi was carrying an estimated 800,000 barrels of oil when it ran aground. Estimates of the spill's surface area also vary.

Greenpeace satellite imagery analysis shows Greenpeace estimated the oil spill covered approximately 1,300 square kilometers (500 square miles) as of August 6, 2026, whereas SkyTruth satellite imagery analysis shows John Amos of SkyTruth estimated the oil spill covered more than 2,000 square kilometers (770 square miles) as of August 6, 2026. Details regarding the specific impact location show variation, with one report noting that on August 12, 2026, the Environment Authority of Oman reported that oil pollution from the grounded vessel Caroline Bezengi had affected some beaches in the Ras Madrakah area, with an expected affected coastal stretch of up to 40 kilometers, while another states the oil spill from the Caroline Bezengi has reached the coastline of Ras Madrakah in Oman. Cargo estimates further diverge between the shipping data analysis figure of an estimated 800,000 barrels and the SkyTruth vessel capacity analysis where John Amos of SkyTruth estimated that the Caroline Bezengi could have been carrying as much as 40 million gallons of oil. John Amos of SkyTruth provided multiple estimates, including that the Caroline Bezengi could have been carrying as much as 40 million gallons of oil and that the oil spill covered more than 2,000 square kilometers (770 square miles) as of August 6, 2026.

Why It Matters

The spill impacts the Hallaniyat Archipelago, which was designated a marine reserve in 2025. This area is home to protected marine life including sea turtles, sharks, humpback whales, and Socotra cormorants. The determination by the International Oil Pollution Compensation Funds that it would not be involved in the cleanup because the incident likely resulted from an act of war raises questions about long-term funding and liability for the response efforts.
