Asphalt Tanker Rams Docked Riverboat in New Orleans, Capsizing Vessel

A 160-meter Marshall Islands-flagged asphalt tanker capsized a docked U.S. river cruise ship on the Mississippi River in New Orleans on Friday, sending passengers into the water and prompting the U.S. Coast Guard to shut the waterway between mile markers 93 and 96. More than 30 people were hospitalized, though none in critical condition, and local officials said no passengers remained unaccounted for.

The tanker Atlantic Asphalt struck the port side of the 81-meter American Heritage, a U.S.-flagged paddlewheel cruise ship operated by American Cruise Lines, at about 12:30 p.m. local time below the Crescent City Connection bridge, according to the Port of New Orleans. The collision occurred while the riverboat sat docked alongside the city's riverfront.

About 129 passengers, plus crew members, were aboard the American Heritage at the moment of impact, Port NOLA said. Video of the incident circulating online shows the tanker driving into the stationary vessel, after which the American Heritage took on water, rolled over and capsized alongside the dock. Other footage shows people wearing life jackets in the water as rescuers arrived.

What do we know about the two vessels?

Vessel-tracking data from MarineTraffic shows the American Heritage had arrived from Natchez, Mississippi, and docked in New Orleans earlier on Friday. The platform recorded a "proximity event" involving the Atlantic Asphalt at 18:29 UTC — 12:29 p.m. local time — matching the reported collision time.

The American Heritage, built in 2015, is a 150-passenger paddlewheel river cruise ship with multiple passenger decks, private balcony accommodations and a traditional stern paddlewheel design. It operates cruises along the Mississippi River and other U.S. inland waterways.

The Atlantic Asphalt's recent trading pattern raises its own questions. AIS data shows the tanker called at Amuay, Venezuela, in mid-October before arriving in Paulsboro, New Jersey, on October 24. It departed Paulsboro on October 26 and reached New Orleans on November 11, two days before the collision.

Why does the tanker's voyage matter?

The voyage coincided with the Trump administration's emergency Jones Act waiver, which permits certain foreign-flagged vessels to carry domestic cargo between U.S. ports. The Atlantic Asphalt does not appear in the Maritime Administration's latest waiver report, however.

It remains unclear whether the tanker loaded cargo in Paulsboro for delivery to New Orleans — a move that would generally require a Jones Act waiver — or whether it was simply continuing an international voyage after discharging part of its foreign-loaded cargo in New Jersey.

How did operators and authorities respond?

American Cruise Lines confirmed the collision and the evacuation. "We are in close coordination with the U.S. Coast Guard and local authorities. Guests and crew were evacuated, and we are deeply concerned for everyone involved. We will share more information as it becomes available," the company said in a statement.

The collision triggered a major multi-agency emergency response involving the Coast Guard, the New Orleans Fire Department, police, EMS and Port NOLA Harbor Police. The mayor's office said rescuers had pulled multiple people from the water and that search-and-rescue operations were ongoing. Passengers were taken to the Port of New Orleans Administration Building for assistance and medical evaluation.

Louisiana Governor Jeff Landry said he had been briefed on the incident and was in contact with local officials as the response continued.

What happens next on the river?

The Coast Guard has closed the Mississippi to all vessel traffic between mile markers 93 and 96 while responders assess the situation, a closure that halts barge and ship movements through a critical stretch of one of America's busiest freight corridors.

The cause of the collision remains under investigation. Authorities have not said whether the tanker suffered a mechanical or propulsion failure before impact. With the riverboat capsized at the dock and the waterway shut, shippers and operators on the Lower Mississippi should expect delays and detentions until salvage and investigation work clears the channel.
