A British Firm Starts Containment of Oil Spill from Stricken Tanker off Oman

A British maritime risk and response company, Ambrey, has been contracted to address an oil spill from a grounded Russian tanker off the coast of Oman. The vessel, identified as the Caroline Bezengi, ran aground in early June following an unexplained explosion. The tanker, believed to be part of Russia's "shadow fleet," was carrying an estimated cargo of over 800,000 barrels of oil.

This is an extremely challenging situation, compounded by adverse weather conditions associated with the Khareef monsoon.

Satellite imagery reveals that the oil slick has expanded exponentially over hundreds of square kilometers, particularly during stormy weather associated with the region's "Khareef" monsoon season. This dramatic spread poses a severe threat to a marine protected area near Qabiliyah Island, which is home to coral reefs, seagrass meadows, endangered turtles, and the rare Arabian Sea humpback whale. The oil has already reached the shores of Ras Madrakah, over 200 kilometers north of the grounded vessel.

Ambrey's personnel, with assistance from the Omani air force, have boarded the tanker to assess its condition and begin stabilization efforts. However, the company acknowledges the extreme challenges posed by the adverse weather. No estimates have been provided regarding the duration or cost of the salvage operation. Experts warn of a potential unprecedented environmental disaster if the tanker sinks or its entire cargo is released.

It is extremely concerning that the oil has spread from an offshore spill to the shoreline where it can contaminate coastal sediments.

Environmental groups have expressed deep concern. Hanen Keskes of Greenpeace highlighted the added complexity of cleanup now that the oil has reached the shoreline, potentially contaminating coastal sediments. She noted that the environmental impact could persist for years, even after the slick is contained. The remote location and lack of infrastructure in the affected area further complicate salvage and containment efforts, necessitating enhanced safety measures.

It can make the cleanup significantly more complex than containment at sea. Even after the slick has been contained and removed, the environmental impact can last for years.
