  • Patent number: 5373925
    Abstract: An underwater deployment and storage apparatus for a diving bell or the like has a reel assembly (7) with spaced flanges (9,10) to contain an umbilical services assembly (5) wound around a hub (7A) of the reel. A rotary union (12) mounted in the hub has a fixed assembly or static line (11) about which the hub rotates. The fixed assembly receives services such as gases, liquids, electricity, fibre optics and the like and feeds to a rotatable assembly connected with the hub. The umbilical services are coupled to one of the umbilical. A first drive motor rotates the reel in either direction. A second drive motor and fairlead (6) extract from or rewind the umbilical onto the reel. Both drive motors are synchronized under controls to exert and maintain either a tractive or a drag force on the run of the umbilical.
