Port turns to federal court after the collision
The Port of New Orleans has filed a federal lawsuit seeking control of the tanker Atlantic Asphalt after it struck the docked American Heritage river cruise ship on November 13. The Associated Press reported that a judge issued a warrant allowing federal officials to take control of the tanker while investigators examine the collision. The port alleges that damage to its Thalia Street terminal exceeds $1 million. Those civil allegations have not been adjudicated, and the cause of the collision remains under investigation. [2]
A cruise ship rolled onto its side
The 520-foot Atlantic Asphalt struck the American Heritage at about 12:30 p.m. while the cruise ship was at the New Orleans riverfront. The impact caused the paddlewheel vessel to capsize beside the terminal. AP reported that all 197 passengers and crew aboard the cruise ship, as well as the tanker crew, survived. Thirty-two people were taken to hospitals, including two police officers who went into the river during the emergency; officials said none of the injuries was critical, although eight people remained hospitalized on Saturday.

The tanker manager confirms an allision
OSM Thome, which manages the Atlantic Asphalt, confirmed that the Marshall Islands-flagged tanker was involved in what maritime law calls an allision: contact between a moving vessel and a stationary vessel or structure. The company said the master immediately reported the incident to the U.S. Coast Guard, the tanker crew was safe and the vessel later separated from the passenger ship and remained stable. OSM Thome said it activated its emergency response team and was cooperating with authorities. Its statement did not identify a cause. [1]
Investigators face two vessels and a damaged terminal
The National Transportation Safety Board sent investigators to New Orleans, according to AP. The inquiry is expected to examine steering and propulsion systems, navigation data, bridge communications, pilotage and the actions taken before impact. The overturned American Heritage still contains roughly 16,000 gallons of fuel, which officials must remove safely before the vessel can be recovered. The Atlantic Asphalt was moved away from the scene, while restrictions remained around the casualty and river traffic was being restored in stages. [1] [2]
What is known — and what is not
Officials have not established why the tanker moved toward the terminal or whether mechanical failure, human action, river conditions or another factor caused the collision. The port’s lawsuit is a claim for civil relief, not a finding of fault. The investigation may also address how the evacuation unfolded and why a mass-casualty event ended without a death. Investigators will also assess navigation records, communications and the vessels’ mechanical condition. The next reliable evidence will come from federal investigators, Coast Guard orders, court filings and technical inspection records. Until those records are available, assertions about negligence or criminal conduct would be premature. The Decoder will update this report when an official finding or material court development changes the public record, while preserving the original publication date. [1] [2]
