Bridge collapse: Temporary channel opens for boats working on response

Ten ships -- not including the Dali -- are stuck inside the Port of Baltimore, according to a new update by the Bureau of Transportation Statistics.

They are comprised of: three bulk carriers, one vehicle carrier, three logistics naval vessels, two general cargo ships and one oil chemical tanker.

An additional vehicle carrier is in the port but outside the site of the bridge collapse.

This list does not include additional tugboats, sailboats and private yachts that are also in a holding pattern as the Port of Baltimore remains closed.

The port said Tuesday vessel traffic in and out is "suspended until further notice."

Dali, the container ship that struck the Francis Scott Key Bridge, "experienced momentary loss of propulsion" just before the collision, the Maritime and Port Authority of Singapore confirmed.

The Singaporean-flagged ship underwent and passed two separate inspections in June and September 2023, the Maritime and Port Authority of Singapore said in a statement.

"Based on records, the Maritime and Port Authority of Singapore confirms that the vessel’s required classification society and statutory certificates covering the structural integrity of the vessel and functionality of the vessel’s equipment, were valid at the time of the incident," Singapore’s port authority said.

"In the June 2023 inspection, a faulty monitor gauge for fuel pressure was rectified before the vessel departed the port," MPA added.

The closure of the waterway will immediately impact the arrival or departure of eight foreign cargo vessels and four U.S. cargo vessels, according to an updated assessment obtained by ABC News.

From March 26 to April 9, arrivals into the Port of Baltimore of an estimated two chemical tank ships, five container ships, 15 vehicle carriers and 13 bulk carriers may be impacted.

One cruise vessel is anticipated to arrive on April 4, which may also be impacted.

Imagery from underwater drones show "an abundance of twisted metal and debris" from the collapsed bridge, making it unsafe for divers to enter the frigid water to search for the six missing construction workers, according to a new assessment of the situation from the Department of Homeland Security obtained by ABC News.

One truck and trailer have been recovered, and one vehicle remains hanging from the metal structure, according to DHS.

The 23 ship crew members are all accounted for, and one was transported to a local hospital with a minor injury, the document said.

With the Port of Baltimore closed to maritime traffic, transportation officials expect backups to rail and truck freight shipments as cargo shifts along the eastern seaboard, the document said.

Investigators have determined there are 13 damaged containers aboard the ship and they are being inspected for any potentially hazardous materials, DHS said.

"There is minor sheening on-scene. Booming has been ordered and is staged but will not be placed until search and rescue and dive operations are complete," the document said. "The amount of potential oil spill is 1.8M gallons of marine grade diesel."
