BALTIMORE (AP) — The owner and manager of the cargo ship that caused the deadly Baltimore bridge collapse recklessly cut corners and ignored known electrical problems on the vessel, the Justice Department alleged Wednesday in a lawsuit seeking to recover more than $100 million that the government spent to clear the underwater debris and reopen the city’s port.

The lawsuit filed in Maryland provides the most detailed account yet of the cascading series of failures on the Dali that left its pilots and crew helpless in the face of looming disaster.

The Justice Department alleges that mechanical and electrical systems on the massive ship had been “jury-rigged” and improperly maintained, culminating in a power outage moments before it crashed into a support column on the Francis Scott Key Bridge in March. Six construction workers were killed when the bridge toppled into the water.

“This tragedy was entirely avoidable,” if not for the companies’ decision to place an “ill-prepared crew on an abjectly unseaworthy vessel,” says the lawsuit against Dali owner Grace Ocean Private Ltd. and manager Synergy Marine Group, both of Singapore.

“They did so to reap the benefit of conducting business in American ports. Yet they cut corners in ways that risked lives and infrastructure,” the complaint says.

Darrell Wilson, a Grace Ocean spokesperson, said the owner and manager had no comment on the merits of the claim but “look forward to our day in court to set the record straight.”

Justice Department officials refused to answer questions Wednesday about whether a criminal investigation into the collapse remains ongoing. FBI agents boarded the vessel in April.
