A subsidiary of Greek shipowner Navios Maritime Holdings has been fined $2m in the US for illegal discharge of oily waste.

Footage released by the US Department of Justice (DoJ) shows oily water being released into the sea from the 75,000-dwt Nave Cielo (built 2007).

The DoJ said Navimax Corporation, incorporated in the Marshall Islands with its main offices in Greece, was sentenced by a federal district court for violating the Act to Prevent Pollution from Ships and obstructing a Coast Guard investigation.
