Oman says massive oil spill reaches coastline: What damage could it do?

A vast oil spill from a leaking tanker reached Oman’s coastline on Wednesday, its environment agency said.

This oil spill threatens to become one of the world’s worst in years after spreading largely unchecked for several weeks, experts say.

On Monday, Oman said it was working to contain the spill, which had by then affected roughly 390 square kilometres (150sq miles), according to analysis by the country’s environment agency.

The slick now covers an area of more than 2,000sq km (770sq miles), said John Amos, an oil spill specialist who reviewed satellite imagery obtained by Reuters. It could affect about 40km (25 miles) of coast near Ras Madraka, as well as Masirah Island, Oman’s Environment Authority said.

Oil has been leaking from the tanker Caroline Bezengi since it ran aground about 22 nautical miles (41km) from the Omani coastal town of Sharbithat some time after the crew reported a suspected explosion on June 8. It had been en route from Russia to India.

Reuters reported that the tanker was carrying an estimated 800,000 barrels of sanctioned oil and that it ran aground on June 30.

An investigation by the news agency AFP found that the ship had been stranded for several weeks near Oman’s al-Qibliyyah Island.

In the meantime, the oil has been spreading towards Oman’s coastline.
