Abstract: A system, an arrangement and a method, all for motion damping of a floating marine structure. Also disclosed is a use of the system. The system has at least one dampening device configured to dampen a movement in one direction and allowing a movement in the opposite direction, and a suspension arrangement has a respective wire configured to suspend the at least one dampening device hanging at a suspended depth in the water from the marine structure and with the dampening device oriented so that a dampening force induced by the dampening device is subjected in the extension of the wire. Also, each dampening device is a passive damping device has a valve structure configured to dampen a movement in one direction and allowing a movement in the opposite direction essentially without damping interaction.
