Omani Authorities Contain Expanding Oil Spill from Sanctioned Russian-Linked Tanker

Core Event: Grounding and Leak of the Caroline Bezengi
On June 8 2026 the Suezmax tanker Caroline Bezengi ran aground off Oman’s Hallaniyat Islands after its crew reported an explosion. The vessel, loaded with close to one million barrels of Russian crude bound for Asia, ceased transmitting AIS signals on June 11 2026. Water entered multiple compartments and crude began leaking into the Arabian Sea. By early August the oil slick was approaching the Omani shoreline, prompting a multi-agency response.
Background & Context: Shadow-Fleet Sanctions and Marine Reserve
The Caroline Bezengi is listed as part of Russia’s “shadow fleet,” operating under the Cameroonian flag and subject to EU, UK, Canadian and Swiss sanctions. The grounding occurred within the Hallaniyat archipelago, a marine reserve created in 2023 to protect coral reefs, turtle nesting sites and humpback whales.
Timeline of Key Developments
- June 8 – Crew reports explosion; vessel grounds near al-Qibliyyah Island.
- June 11 – Last AIS transmission recorded off Yemen.
- July 18 – Initial reports of oil leaking in the protected area.
- July 23 – Oman’s Ministry of Transport orders owners to remove the vessel and cargo.
- August 5 – Satellite images show the tanker more submerged and an oil sheen extending northeast.
- August 6 – Authorities announce monitoring through satellite imagery, field surveys and technical modelling.
- August 10 – Omani Environment Authority states the slick covers about 390 sq km (?150 sq mi).
Data & Statistics: Extent of the Slick
- Omani Environment Authority: ? 390 sq km, within 7 km of the coast.
- Greenpeace: ? 600 sq km.
- PAX (Dutch organization): ? 800 sq km as of August 7.
Differences reflect observation dates, imaging methods and the spill’s evolution.
Official Statements & Responses
A Transport Ministry official said authorities were conducting aerial surveillance, deploying divers and planning to transfer the cargo to reduce navigation risks.
Dr. Abdullah bin Ali Al-Amri, chairman of the Environment Authority, reported continuous seawater testing shows “no cause for concern” for desalination plants, aquaculture or tourism.
Mohammed bin Abdullah Al-Rawahi, Director General of Maritime Affairs, said the priority is halting pollution, securing the vessel and safely off-loading the oil while protecting response personnel and navigation safety. He noted coordination among the Royal Air Force of Oman and the Royal Oman Police Coast Guard under the National Oil Spill Contingency Plan.
Conflicting Reports & Gaps
The main discrepancy lies in slick size: 390 sq km (Omani officials), 600 sq km (Greenpeace) and 800 sq km (PAX). No party has claimed responsibility for the June 8 explosion, and the hull breach cause remains unconfirmed. Satellite imagery confirms the vessel’s increasing submergence, but authorities have not disclosed whether salvage or off-loading operations have begun.
Verbatim Quotes
- “Over the past few days the images show more and more oil coming out, since the surface of the slick keeps growing,” — Vim Zvajnenburg, PAX.
The Omani response continues to rely on satellite monitoring, field surveys and technical modelling while the spill drifts toward the mainland, highlighting the challenges of containing a large-scale oil release within a protected marine ecosystem.
