Greek manager Chartworld Shipping has pleaded guilty in the US to presenting falsified documents to the US Coast Guard (USCG) in a reefer pollution case.

Owner Nederland Shipping Corp also admitted the offence.

A US department of justice statement said the two companies also pleaded guilty to not notifying the USCG of the 627,986-cbf Nederland Reefer’s (built 1991) hazardous condition after a hole developed in the vessel’s bilge water tank, compromising the hull’s integrity.
