GULF OF ALASKA (AP) — The long, lonely voyage of the Japanese ghost ship is over. A U.S. Coast Guard cutter unleashed cannon fire on the abandoned 164-foot Ryou-Un Maru April 5, ending a journey that began when last year’s tsunami dislodged it and set it adrift across the Pacific Ocean.
It sank into waters more than 6,000 feet deep in the Gulf of Alaska, about 180 miles west of the southeast Alaska coast, the Coast Guard said.
The crew pummeled the ghost ship with high explosive ammunition, and Ryou-Un Maru soon burst into flames, took on water and began listing, officials said. A huge column of smoke could be seen over the gulf as a Coast Guard C-130 cargo plane, sent to observe the sinking, dropped a buoy to monitor for any possible pollution from the sunken ship.
The Coast Guard warned mariners to stay away, and aviation authorities did the same for pilots. In about four hours, the ship vanished into the water, said Chief Petty Officer Kip Wadlow in Juneau.
Officials decided to sink the ship rather than risk the chance of it running aground or endangering other vessels in the busy shipping lanes between North America and Asia.
The ship had no lights or communications system, and its tank was able to carry more than 2,000 gallons of diesel fuel. Officials, however, didn’t know how much fuel, if any, was aboard.
“It’s less risky than it would be running into shore or running into (maritime) traffic,” said Coast Guard spokesman Paul Webb.
The National Oceanic and Atmospheric Administration and the Environmental Protection Agency studied the problem and decided it was safer to sink the ship and let the fuel evaporate in open water.
A light sheen and minimal debris were visible as the vessel sank, but the sheen is expected to quickly dissipate, the Coast Guard said in a news release.
The ship was at Hokkaido, Japan and destined for scrapping when a magnitude 9.0 earthquake that struck the country in March 2011 triggered a tsunami.
The waves dislodged the vessel and set it adrift. In total, about 5 million tons of debris were swept out to sea.
The boat did not have any cargo aboard, Webb said. He said he didn’t know who owned Ryou-Un Maru, which had been traveling at speeds less than 1 knot in recent days.
As the Coast Guard was readying to fire on the vessel, a Canadian fishing vessel, the 62-foot Bernice C, claimed salvage rights to the ghost ship in international waters. Plans to sink it were halted so the Canadian crew could have a chance to take the stricken ship. A Canadian official with knowledge of the situation told the Associated Press that the Bernice C was unable to tow it. Once the Canadian boat left, the Coast Guard began to fire — first with 25 mm shells, then a few hours later with ammunition twice that size.
In the year since the tsunami, debris from Japan has washed up on shores across the Pacific.
In January, a half dozen large buoys suspected to be from Japanese oyster farms appeared at the top of Alaska’s panhandle and may be among the first debris from the tsunami.
State health and environmental officials have said there is little need to be worried that debris landing on Alaska shores will be contaminated by radiation. However, the earthquake triggered the world’s worst nuclear crisis since the Chernobyl accident in 1986.
State officials have been working with federal counterparts to gauge the hazards of debris, including material affected by a damaged nuclear power plant, to see if Alaska residents, seafood or wild game could be affected.
