National Transportation Safety Board Chair Jennifer Homendy said there is a lot of information that officials need to collect following the collapse of Baltimore's Francis Sott Key Bridge.
A team of 24 experts will dig into nautical operations, vessel operations, safety history records, owners, operators, company policy and any sort of safety management systems or programs, Homendy said.

The National Transportation Safety Board (NTSB) is giving an update on the collapse of the Francis Scott Key Bridge in Baltimore early Tuesday after it was hit by a container ship.
Officials said at least six people are still unaccounted for and search and rescue operations are underway. There was a crew of construction workers on the bridge when it fell, according to authorities.
The NTSB already launched a "go team" to investigate the incident, it said earlier Tuesday. This team consists of technical experts and specialists across the agency on rotational duty assignment to respond as quickly as possible, it said.

The US Embassy in Singapore has been in contact with the country’s Maritime and Port Authority, in the wake of the Francis Scott Key Bridge collapse in Baltimore, State Department spokesperson Matthew Miller said Tuesday.
Miller said Singapore’s Maritime and Port Authority “has offered to provide assistance to the US Coast Guard.”
The tanker, which collided with the bridge causing the collapse, was Singapore-flagged and bound for Sri Lanka, but Miller said he was “not aware of any contacts with Sri Lanka.”
The ship was chartered by Danish shipping company Maersk and was carrying their customers' cargo, the Danish shipping company told CNN. It also said the ship, DALI, is operated by charter vessel company Synergy Group.

The president of the International Longshoremen’s Association Local 333 in Baltimore, Maryland, said the collapse of the Francis Scott Key Bridge will have major consequences for the port’s workforce and the state’s economy for the foreseeable future.
"We are at a standstill, we make our living off of import and export cargo, unloading and loading, discharging and loading ships," Scott Cowan, president of ILA Local 333, said. "This is going to put a very big strain on the economy in the state of Maryland because the port of Baltimore is one of the main engines, main drivers of the economy of Maryland, this is going to create a big problem."
The ILA’s work relies on the flow of cargo ships through the port as its workers are responsible for securing loads on and off the deck, operating the cranes and running the boxes throughout the yard.
"Until those ships can come up and down the bay, the little bit of cargo that's in the terminal will be imported and exported out and then we'll be waiting for the channel to open — I don't know how long it's going to take," Cowan added.
Cowan said that these massive cargo shops are very difficult to stop — especially when you face issues with power outage and propulsion.
"This is not like a car, they don't have brakes," Cowan said.

Ocean carriers are being moved away from the Port of Baltimore after the Francis Scott Key Bridge collapsed on Tuesday. The Port of Virginia and the Port of Baltimore are coordinating diverting the ships to the Port of Virginia to eliminate the traffic in Baltimore’s port to “keep trade moving."
The Virginia and Maryland Departments of Transportation are also working to ensure uniform signage along roads “all the way up from Virginia into Maryland,” Virginia Gov. Glenn Youngkin said.
“We have our first ocean carrier that was supposed to be heading to Baltimore making a stop in Virginia and unloading all of their Baltimore cargo here. We've got capacity to do it, and I think that's really important,” Youngkin said.
"We've got high-level interaction everywhere needed and we just wait to be called and as soon as we are, we'll be moving," he added.
