A reeling device

A reeling device for the controlled coiling and uncoiling of a payload cable, the reeling device comprising an axial shaft and a reel mounted on the axial shaft for rotation about the axial shaft, a nut member and at least one roller mounted on the nut member, wherein

• the reel has an outer surface about which a length of cable is adapted to be wrapped,
• the nut member substantially surrounds the reel and is radially spaced from the outer surface of the reel,
• the outer surface of the reel is provided with a helical groove for receiving one or more payload cables, and
• the at least one roller is adapted to rotate while engaging the helical groove,
• the reeling device further comprising:
• a diverter sheave directly or indirectly connected to the nut member arranged to receive a payload cable from the reel and divert the payload cable in a first direction, and
• a compensator sheave arranged to receive said payload cable from the diverter sheave and divert the payload cable in a second direction different to the first direction,
• wherein the diverter sheave and compensator sheave are arranged for concurrent movement in the longitudinal direction of the axial shaft.
