According to the US Coast Guard (USCG) the 156,700-dwt Everbright(built 2010) was held on the heels of an inspection that found infractions related to the vessel’s oily water separator.

“The crew could not conduct a satisfactory operational equipment test of the oily water separator (OWS),” the agency wrote in a report detailing the deficiencies that led to the detention, adding:

“When the sample line was opened, the oil content meter rose above 15 parts per million, but the three-way valve would not actuate at any time.
