Efforts to remove the cargo of an oil tanker that leaked oil into the Yellow Sea near China's Qingdao after a collision last week should be completed later on Tuesday, the vessel's manager said. The A Symphony was anchored roughly 40 nautical miles off the coast of Qingdao when it was struck in dense fog by the bulk carrier Sea Justice on April 27. The collision ruptured A Symphony's cargo and ballast tanks, causing it to leak roughly 400 tonnes of its bitumen mix cargo.
