General average is expected to be declared imminently after the container ship Dali struck and brought down part of the Francis Scott Key Bridge in Baltimore.

When general average is declared, cargo and vessel interests share in the cost of a casualty, but the sums involved can take years to establish, particularly for a boxship with multiple interests.

The 9,962-teu Dali (built 2015) struck the bridge on 26 March, less than an hour after it left its berth at the Port of Baltimore.
