Greece's Sea World Management and Trading has said a master convicted in the US of oily waste dumping "acted unilaterally."

The company and master Edmon Fajardo pleaded guilty under a plea bargain agreement with the US department of justice (DoJ).

The charges were failing to accurately maintain the 46,000-dwt tanker Sea Faith’s (built 2003) oil record and garbage record books and illegally discharging oily waste and dumping garbage while operating off the coast of Texas in March last year.
