The captain of an Aegean Shipping chemical tanker that made illegal discharges into the sea pleaded guilty on Thursday to obstructing a US Coast Guard (USCG) investigation of those crimes.
Filipino citizen Genaro Anciano entered his plea in federal court in Charleston, South Carolina.
The case concerns instances in 2015 when the Greek-owned Green Sky used a so-called “magic pipe” device to bypass pollution prevention equipment and discharge bilge into the sea.
The ship’s oil record book was also tampered with to hide the illegal discharge.
Anciano’s guilty plea effectively means he admits making misleading statements to the initial USCG probe of the incidents in an attempt to cover them up.
A sentencing date has not yet been set.
