Greek owner New Trade Ship Management has agreed to pay a $1.1m fine over illegal discharges of oily bilge water from one of its vessels in US waters.

The shipowner and Dennis Plasabas, chief engineer of the 34,400-dwt Longshore (built 2010), pleaded guilty on Tuesday in San Diego, California, to charges of maintaining false and incomplete records relating to the discharge.

New Trade and Plasabas admitted that oily bilge water was illegally dumped from the Longshore directly into the ocean without being properly processed through required pollution prevention equipment, the US Department of Justice said.
