Damper and damper system for damping relative lateral movement between a tensioned cable and a support structure

A damper system for damping oscillations and vibrations of a cable that is connected to a support structure, comprising a passive damper for damping relative lateral movement between a cable and a support structure, said passive damper comprising;

• a first fixture element configured to be rigidly connected to said cable, and
• a second fixture element configured to be rigidly connected to said support structure,
• at least one rotational damping device is arranged between the first and second fixture elements,
• said rotational damping device being configured to translate said relative lateral movement into relative rotational moment between at least two arms of said rotational damping device that are connected at a rotational joint, said rotational joint having when in use, a rotational axis Y substantially parallel with a longitudinal axis X of said cable,
• wherein said first fixture element comprises a first opening for allowing said cable to extend through said first opening, and wherein said second fixture element comprises a second opening for allowing said cable to extend through said second opening.
