Bottom line: When Storm Dennis battered the coast of Ireland in early 2020, it brought with it a mystery. Alta, which was built in 1976, had been floating around the Atlantic with a cargo of intact oil barrels but no humans for at least 18 months before it reached Ireland’s shore. In October 2018, as it traveled from Greece to Haiti, its engines failed, and its crew was saved by the U.S. Coast Guard near Burmusa.
No one knows what happened to the abandoned ship after that. Some believe another ship attempted to tow it Guyana, only to abandon it again. When they cut it loose, it slowly drifted around the Atlantic before it grounded in Ireland.
The government begged people to stay away from the wreckage due to its dangers, but they continue to board to take photos. In April 2021, someone started a fire on the ship, which was put out before it could spread.
The ship remains stranded as a salvage operation would potentially cost millions, and its owners have not been identified.
