Coal exporter Consol Energy has filed a claim for more than $100m it suffered in losses over the collapse of Baltimore’s Francis Scott Key Bridge.

The US company’s claim against shipowner Grace Ocean and manager Synergy Marine is the latest in a complex legal battle concerning the 9,962-teu container ship Dali (built 2015), which struck the bridge in March.

Consol Energy said in a court filing that the destruction of the bridge, which killed six people, cut off its Baltimore coal export terminal from international markets during the Patapsco River’s eight-week closure.
