Three seafarers are seeking compensation for being detained for two months in the US after exposing illegal oil dumping by German ship manager Mineralian Schiffahrt Sedition und Transport.

Third engineer Jarolsav Hornof of Czechoslavakia, oiler Damir Kordic of Croatia and wiper Lukas Zak of Slovakia saw "improper discharges" of oil from the 27,700-dwt Marguerita (built 2016), according to court documents.
