PORT LOUIS: A ship that has leaked more than 1,000 tonnes of oil in pristine waters off the coast of Mauritius has split in two.

The bulk carrier MV Wakashio ran aground on a coral reef off the southeastern coast of Mauritius on July 25 and began oozing oil more than a week later, threatening a protected marine park boasting mangrove forests and endangered species.

Mauritius declared an environmental emergency and salvage crews raced against the clock to pump the remaining 3,000 tonnes of oil off the stricken vessel.ARTICLE CONTINUES AFTER AD

“It was confirmed on August 15 that the vessel has broken into two,” the ship’s operator Mitsui OSK Lines said in a statement on Sunday, noting that the information came from the vessel’s owner, Nagashiki Shipping.

The split was caused by a crack in a cargo hold on its stern side, Mitsui said.

Officials had been preparing for the development for days, and images taken on Saturday indicated it was inevitable, with the two pieces only partially attached.

Nearly all the remaining 3,000 tonnes of oil had been pumped off the ship by that time, though there were still 90 tonnes on board, much of it residue from the leakage.

Mitsui noted on Sunday that “an amount of unrecovered oil is believed to have leaked out of the vessel”, without providing details.

Thousands of Mauritians have volunteered day and night to clean the powder-blue waters that have long been a favourite among honeymooners and tourists.

The spill is both an environmental and economic disaster for Mauritius, which relies heavily on tourism.

The spill already qualifies as the “worst ecological disaster” for the Indian Ocean island nation, Greenpeace Africa campaigner Happy Khambule said, adding that it “puts unique species under immediate threats”.

Now that the ship has split, the salvage team intends to pull the front two-thirds out to sea using two tugboats to avoid further damage to the Mauritian coastline, a police official in the capital Port Louis said, speaking on condition of anonymity because he was not authorised to brief the media.

The remaining portion is still stuck on the reef and officials have not yet determined how they might remove it, the official said.

That portion includes the ship’s engine room, which still contains 30 cubic metres of oil, and rough weather will complicate efforts to pump that oil out, according to a statement on Sunday from the Mauritian crisis committee formed to respond to the spill.

The crisis committee expects rough weather for the next five days.
