  • Rotary cable treatment method and apparatus
    Patent number: 6783593
    Abstract: A rotary cable treatment assembly for use on cables having a non-circular cross section formed from a stator that housing a rotor formed from two hydraulically sealing bearings. A cable having a non-circular cross section is passed through the assembly wherein a lubricant or high viscosity inhibitor is pressurized to about 3000 psi within the assembly causing the fluid to coat all internal strands that form the cable. The rotor and hydraulically sealing bearings rotate according to the helix of the cable to reduce or eliminate wear on the cable and sealing.
    Type: Grant

  • Fixed umbilical cable flotation docking head
    Patent number: 6536743
    Abstract: The instant invention teaches a docking head having a sheave which is capable of translating position within its plane or rotation so as to alter the placement of its axis of rotation, thereby allowing the docking head to safely accommodate umbilical cable mounted fixed floatation devices. The system senses the floatation presence and automatically shifts the sheave to allow trouble free passage of the floatation up to and including the step of latching the payload.

  • Method and apparatus for umbilical floatation storage
    Patent number: 6443383
    Abstract: In a system for recovery of marine ROVs, an umbilical is wound around a winch drum. A portion of the umbilical has foam floatation segments that may be damaged by wrapping about the drum. A flexible belt is inserted between the wrapped portion of the umbilical and the floatation segments to prevent damage to the floatation segments.
