D'Amico has denounced the actions of two engineers that resulted in a guilty plea for environmental crimes in a US federal court.
The Italian shipowner, whose 40,100-dwt Cielo di Milano (built 2003) is at the centre of the criminal case, also said that its policies and instructions to crew members require them to "absolutely follow" environmental rules and regulations.
Plus, they must follow the company's own internal requirements, which it says are often more stringent.
The Paolo D'Amico-led company expressed the "gravest disappointment" over the admissions by chief engineer Girolamo Curatolo and first assistant engineer Danilo Maimone that they concealed the discharge of oily waste from the products tanker.
"We denounce the actions of these two former engineers and appreciate the work of the US Coast Guard and other members of our sea staff around the world for their efforts to safeguard our environment," d'Amico said in a statement provided to TradeWinds.
Curatolo, 50, and Maimone, 31, pleaded guilty in a federal court in Newark, New Jersey, conspiring to violate the Act to Prevent Pollution from Ships, which codifies the International Convention for the Prevention of Pollution from Ships (Marpol).
Sentencing is scheduled for November.
