Oil Spill from the Sanctioned Tanker Caroline Bezengi Threatens Oman’s Marine Reserve

Core Event – Grounding and Leak
On June 30 2026 the Suezmax tanker Caroline Bezengi ran aground near Al-Qibliyyah Island in Oman’s Hallaniyat archipelago. The vessel, carrying about 800,000 barrels (?130,000 tons) of Russian crude, was under EU, UK, US and Canadian sanctions. The ship first reported difficulties off Yemen on June 8 after an apparent blast; no party has claimed responsibility. Since grounding, the hull has been leaking oil into the Arabian Sea, and the slick is reaching Oman’s mainland.
Background & Context – Shadow Fleet and Regional Conflict
Caroline Bezengi belongs to Russia’s “shadow fleet,” tankers that use foreign flags to evade sanctions. It left Novorossiysk in April, transited the Suez Canal in late May, and then sailed through the Red Sea past Yemen, where Houthi militants have been targeting ships. War-zone navigation and insurance gaps have complicated the emergency response.
Timeline
- June 8 – Crew reports a blast off Yemen.
- June 30 – Caroline Bezengi grounds near Al-Qibliyyah Island.
- July 18 – First public notice of a leak in the protected marine area.
- August 4 – Satellite analysis shows the slick at roughly 600 km².
- August 10 – Omani government announces the slick covers almost 400 km².
- August 12 – Oil reaches up to 40 km of the Ras Madrakah coastline, threatening Masirah Island.
Data & Statistics
- Cargo: ? 800,000 barrels (130,000 tons) of Russian crude.
- Spill size estimates: 390 km² (Omani Authority), 600 km² (Greenpeace), > 2,000 km² (independent analyst).
- Affected coastline: up to 40 km of Ras Madrakah; 10-20 km projected on Masirah Island.
- Response assets: > 100 tons of equipment, salvage vessels, aircraft and specialist teams deployed by Ambrey.
Official Statements & Responses
- Omani Environment Authority emphasized monitoring, deployment of containment booms and protection of high-sensitivity areas.
- International Maritime Organization (IMO) said it is “closely monitoring” the leakage and has contingency plans, noting monsoon-driven access delays.
- Tony Gutierrez, professor of environmental microbiology at Heriot-Watt University, warned that keeping the oil offshore would minimise impact compared with shoreline contact.
Criticism & Opposition – Environmental NGOs
Environmental groups criticize the lack of a clear responsible party, given the tanker’s un-insured, un-flagged status.
On-the-Ground Reports – Satellite and Local Observations
Satellite imagery analysed by John Amos (SkyTruth) shows the slick stretching over 2,000 km². Omani air-force teams have boarded the vessel to assess hull integrity. Local fishermen have been instructed to avoid the affected waters and report any oil sightings.
Conflicting Reports & Gaps
- Spill extent: Omani officials cite ? 390 km², Reuters ? 400 km², Greenpeace ? 600 km², independent analysts > 2,000 km².
- Cause of damage: Sources mention a blast on June 8, an “unidentified incident” on June 6, and speculation about a limpet-mine attack, but no claim of responsibility.
- Liability: The Inter-Oil Pollution Compensation (IOPC) Funds treat the incident as an “act of war,” excluding it from compensation schemes; experts note the lack of a registered owner or insurer leaves Omani authorities bearing the full cost.
What’s Next – Ongoing Salvage and Monitoring
Ambrey’s teams continue to stabilise the hull and are evaluating options to transfer the remaining crude. Monsoon conditions are expected to persist through the Khareef season, potentially delaying further access. The Omani Environment Authority plans weekly satellite-image reviews and may expand booms and dispersant spraying if the slick approaches additional coastal settlements.
