An arrest warrant has been issued for an Interunity Management-controlled ship in a charter dispute with Chembulk Tankers.

Connecticut company Chembulk filed a $2m lawsuit last week in a federal court in Baton Rouge, Louisiana, looking to arrest the 26,198-dwt Chem Ranger (built 2010). In addition to targeting the ship, the lawsuit focuses on registered owner Lantern Maritime as the defendant.

The complaint said Lantern, which Equasis lists at the address of Athens-based commercial manager Interunity, removed the vessel from Chembulk's service on 7 August after Chembulk began raising issues in February.
