Oil from grounded Russian tanker reaches Oman’s mainland as spill spreads

Oil leaking from a grounded Russian crude tanker off Oman's coast has reached the mainland, the United Nations' International Maritime Organization confirmed on Wednesday, as the spill rapidly escalates into one of the worst marine environmental disasters in recent years.

"Oil is drifting offshore to the northeast of Al-Qibliyyah Island, with some oil reported to be reaching the mainland. Oil spill contingency planning is in place," an IMO spokesperson said, adding that seasonal monsoon conditions have limited access to the vessel and delayed salvage operations.newsofbahrain+1

A Slow-Motion Disaster

The Caroline Bezengi, a sanctioned Cameroon-flagged Suezmax tanker carrying an estimated 800,000 to one million barrels of Russian crude bound for Asia, first reported distress off Yemen on June 8 following what maritime sources said appeared to be an explosion on board. The vessel subsequently drifted and grounded on June 30 near Al-Qibliyyah Island in the Hallaniyat archipelago, inside a marine nature reserve established by royal Omani decree last year to protect coral reefs, endangered sea turtles, and an Arabian Sea humpback whale population of roughly 80 animals — the smallest and most isolated humpback population on Earth.reuters+1

Despite the grounding occurring in late June, Oman made its first public disclosure only on Monday, August 10, stating the slick covered approximately 390 square kilometres. Satellite analysis by SkyTruth, a nonprofit conservation monitoring group, now puts the affected area at over 2,000 square kilometres, according to Reuters. Greenpeace's Hanen Keskes noted the rapid acceleration: "The affected area went from around 45 square km by the end of July, to 150 at the beginning of August. And then within two days, it quadrupled to 600 by the 4th or 5th of August."independent+2

Oman's state news agency reported Wednesday that beaches in the Ras Madrakah area — more than 200 kilometres from the grounding site — had been affected, with a coastal stretch of up to 40 kilometres expected to see pollution and potential impact on southern beaches of Masirah Island anticipated within hours.newsofbahrain

Accountability Gap

The vessel is believed to be part of Russia's "shadow fleet" used to circumvent Western sanctions, and was operating under a fraudulent flag registry. The IOPC Funds, an intergovernmental body handling oil spill compensation, told Reuters it would not cover clean-up costs because the incident is being treated as an "act of war" rather than an accident. The tanker is not insured by any recognized Western provider.independent+1

SkyTruth's John Amos warned that without intervention, "A nightmare scenario is there's no adequate response to keep the worst from happening," noting the vessel could "continue to break up under the steady onslaught of wind and waves" and release its entire cargo — a spill that would rival the 1989 Exxon Valdez in magnitude.independent

War at Sea Compounds the Crisis

The spill sits squarely in the path of an intensifying maritime conflict. According to Windward, a maritime analytics firm, 65 commercial ships have been attacked in the Gulf, Strait of Hormuz, and Gulf of Oman since March 1, killing at least 17 seafarers. On Monday, a Houthi attack on a cargo vessel in the Bab el-Mandeb Strait killed crew members — the first fatalities from a Houthi strike on shipping since the Iran war began in February.reuters+1

With no entity clearly responsible for stabilizing the Caroline Bezengi and attacks on hydrocarbon shipping accelerating across the region, the odds of more uncontained spills continue to rise.
