The manager of a US military-contracted tanker that was struck by a cargo ship off England’s northeast coast last month filed a lawsuit at London’s High Court on Monday over the collision.

Stena Bulk Marine Services (USA) and Crowley-Stena Marine Solutions filed a lawsuit against MS Solong Schiffahrtsgesellschaft M&Co KG, a subsidiary of Portuguese-flagged container ship Solong owner Ernst Russ, according to court records.

The case was filed at the specialist Admiralty Court over the collision.

Crowley and Ernst Russ did not immediately respond to a request for comment.

MS Solong Schiffahrtsgesellschaft M & Co KG brought a separate case at the Admiralty Court last week, seeking a “limitation of liability”, according to court records.
