The US Coast Guard yesterday scuttled an abandoned Japanese "ghost ship" that had been washed out to sea near Alaska by last year's devastating tsunami.
The derelict fishing vessel Ryou-Un Maru, which posed a threat to other marine traffic, sank at about 6.15pm local time, nearly five hours after the Coast Guard first opened fire on the ship with machine-gun blasts, Coast Guard Chief Petty Officer Kip Wadlow said.
"The vessel has been sunk and is no longer a navigational hazard in the area."
The cutter crew sent the Ryou-Un Maru to the ocean floor with a series of blasts from a 25mm machine-gun, firing intermittently on the drifting vessel for about an hour, then pausing as the ship caught fire and listed in the sea. The barrage resumed after a two-hour break, and the boat was underwater about two hours later.
The ship's Japanese owner has said it had no plans to salvage the vessel, and Petty Officer Wadlow said it had been scheduled to be scrapped even before it was swept away by the tsunami.
The Ryou-Un Maru was among the 1.5 million tons of debris the Japanese government estimates was dragged out to sea by the immense tidal surge unleashed by last year's Fukushima earthquake, said Ben Sherman, a spokesman for the National Oceanic and Atmospheric Administration.
The Ryou-Un Maru, carrying up to 2,100 gallons of diesel fuel, was about 170 nautical miles southwest of the Alaskan town of Sitka and had been drifting toward busy navigational lanes used by cargo vessels plying the waters of the Great Circle route between North America and Asia, Petty Officer Wadlow said.
The ship was initially spotted by Canadian officials in waters off the coast of British Columbia, and it drifited into US waters on Saturday. The vessel, nearly 61m in length, lacked any lighting, making it a dangerous obstacle at night.
Although most of the tsunami debris expected to hit US coastlines is predicted to arrive in 2013 or later, some items have already washed ashore. In Alaska, most of the marine debris identified as tsunami-related has been buoys and floats from oyster farms.
