A ship that has leaked more than 1,000 tonnes of oil into pristine waters off the Mauritius coast has split into two, its Japanese operator said Sunday. The bulk carrier <em>MK Wakashio</em> ran aground on a coral reef off the south-eastern coast of Mauritius on July 25 and began leaking 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 ship. "It was confirmed on August 15 that the vessel has broken into two," the ship's operator Mitsui OSK Lines said. The information came from the vessel's owner, Nagashiki Shipping, it said. The split was caused by a crack in a cargo hold on its stern, Mitsui said. Officials had been preparing for the development for days, and images taken 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 said on Sunday that "an amount of unrecovered oil is believed to have leaked out of the vessel". The salvage team intends to pull the front two-thirds of the ship out to sea using two tugboats and allow it to sink to avoid further damage to the Mauritian coastline, said a police official in the Mauritian capital Port Louis. The remaining portion is still stuck on the reef and officials have not yet determined how they might remove it, the official said. The weather is expected to become rougher in the coming days, Mauritius' government said on Saturday night, with waves of up to 4.5 metres. The government of Prime Minister Pravind Jugnauth has come under fire, including from opposition leaders, for doing too little in the week after the ship ran aground. It has vowed to seek compensation from the owner and the insurer of the ship for "all losses and damages" caused by the spill as well as for costs related to the clean-up. Nagashiki, the owner, has pledged to "sincerely" respond to requests for compensation over damage to the marine environment. 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 an ecological and economic disaster for Mauritius, which relies heavily on tourism. As of Saturday night, more than 800 tonnes of oil liquid waste and more than 300 tonnes of solid waste sludge and debris had been removed from the ocean. India has sent technical equipment and a team of specialists to Mauritius to help local authorities deal with an environmental crisis after an oil spill from a Japanese ship, a government official said on Sunday. Following a government request for assistance, India dispatched more than 30 tonnes of technical equipment and material by aircraft to supplement the country's salvage operations, the foreign affairs ministry said on Sunday. A 10-member team of Indian coast guard personnel trained in oil spill containment measures has also been deployed to Mauritius to provide technical and operational assistance, it said.
