A crew member told the US Coast Guard that a Dubai-controlled MR tanker was dumping waste oil, landing the owner with a likely $2m fine.

The US Department of Justice (DoJ) said two companies, Prive Overseas Marine of Dubai and Prive Shipping Denizcilik Ticaret of Turkey, pleaded guilty to pollution offences relating to the 51,000-dwt PS Dream (built 2009).

They had been charged with conspiracy, knowingly violating the Act to Prevent Pollution from Ships (APPS) and obstruction of justice related to the falsification of the tanker’s oil record book.
