A Mitsui O.S.K. cargo ship listing in rough seas near Alaska's Aleutian Islands might be leaking fuel from its tanks, the U.S. Coast Guard said. According to Bloomberg, observers have reported a light and broken sheen extending two miles around the vessel, which is carrying 430 metric tons of fuel oil and 112 metric tons of diesel.. Mitsui's Cougar Ace, which has a cargo of at least 4,700 Mazda Motor Corp. vehicles estimated to be worth $117.5m, foundered on July 22 while en route to Tacoma, Wash. A team from salvage company Crowley Marine is due to reach the location of the Cougar Ace, about 230 miles south of the Aleutian Islands, on August 2, with the aim of towing the ship to a nearby port.
