In pleading guilty, Unix Line PTE Ltd. admitted that its crew members onboard the 16,408 gross-ton, ocean-going motor tanker 'Zao Galaxy' knowingly failed to record in the vessel’s oil record book the overboard discharge of oily bilge water without the use of required pollution-prevention equipment, during the vessel’s voyage from the Philippines to Richmond, California.

According to the plea agreement, Unix Line is the operator of the Zao Galaxy, which set sail from the Philippines on 21 January 2019, heading toward Richmond, California, carrying a cargo of palm oil.

On 11 February 2019, the Zao Galaxy arrived in Richmond, where it underwent a US Coast Guard inspection and examination, data by the US Department of Justice reveal.

Examiners discovered that, during the voyage, a ship officer directed crew members to discharge oily bilge water overboard, using a configuration of drums, flexible pipes, and flanges to bypass the vessel’s oil water separator.

The discharges were knowingly not recorded in the Zao Galaxy’s oil record book.

Unix Line’s sentencing hearing is scheduled for March 20 before US District Court Judge Jon S. Tigar in Oakland, California.
