An oil slick in the Singapore Strait from the damaged tanker Natuna Sea has been dispersed and remaining oil on the vessel was being transferred, the Maritime and Port Authority of Singapore (MPA) said on Wednesday. The 5,249 ft. x 2,625 ft. (1,600 x 800 m) oil slick, which had escaped preventive booms placed around the vessel, had been successfully treated with dispersants, an MPA spokeswoman said. At least 7,000 tons of crude oil from estimated total of 40,400 tons was spilled after the Panama-registered tanker ran aground early on Tuesday in Indonesian waters off Batu Berhanti Beacon, approximately five miles south of Singapore. The slick had been heading in a southwesterly direction towards southern Sumatra in Indonesia.
