Singapore's Unix Line has been fined $1.65m in the US for illegally dumping oily bilge water from a tanker.
The company had already pleaded guilty and was sentenced in federal court this week.
Unix admitted that crew on the 26,200-dwt Zao Galaxy (built 2012) knowingly failed to record the overboard discharges without the use of the required pollution-prevention equipment.
The US Department of Justice said the company has also been placed on probation for a period of four years, and ordered to implement a comprehensive environmental compliance plan as a special condition of probation.
