Ship insurer Britannia says it's helping Baltimore bridge collapse probe

Britannia, the insurer of container ship the Dali, is working with the vessel's owner and U.S. authorities on the investigation into the collapse of Baltimore's Francis Scott Key Bridge, Britannia said on Thursday. The bridge collapsed on Tuesday after the Dali suffered a power outage and struck a pylon, causing huge disruption in the port.

"We are working closely with the vessel's owner and manager and the relevant U.S. authorities as part of the investigation into the casualty," Britannia said in a statement.
