Baltimore city officials have filed a petition holding the owner and manager of the Dali container ship responsible for the deadly collapse of the Francis Scott Key Bridge. The ship, owned by Grace Ocean Private Ltd. and managed by Synergy Marine Pte Ltd., struck a bridge support column, causing the span’s collapse and the deaths of six roadwork crew members. The city alleges negligence and argues the companies should have realized the ship’s unfitness for voyage and ensured a competent crew. The ship’s owner and manager are seeking to cap their liability at $43.6 million, but Baltimore officials are seeking full liability for the economic impact, which has halted maritime traffic through the Port of Baltimore.
