Manager Peter Dohle Schiffahrts said on Sunday that all six crew kidnapped from a boxship off Nigeria have been released.
The men were seized from the 3,091-teu Demeter (built 2006) on 21 October.
They have spent the past two and a half weeks in captivity, but are now free and safe.
Demeter was attacked by an armed criminal gang off Onne, Peter Dohle said.
