Definitions

  • This invention relates in general to the field of marine mooring equipment and, in particular, to fairleads used for guiding a mooring line.
  • Fairleads are an important tool in marine environments to guide a line, e.g. a rope, cable or chain, around an object, or to prevent lateral movement of the line.
  • Some fairleads known as moveable fairleads or rotating fairleads, are capable of rotating around a vertical axis to allow for changes in the direction of the line, without having an angle in the line.
  • Figure 1 is a schematic diagram showing a moveable fairlead 1 according to a prior art implementation.
  • the moveable fairlead 1 is generally attached to the hull of a floating vessel such as, for example, a ship or floating platform.

  • the brackets 10 are for attachment to the floating vessel.
  • the brackets 10 may be welded to the hull of the floating vessel.
  • the rotating support shaft 20 is coupled to the one or more brackets and configured to rotate with respect to the brackets 10.
  • a single rotating support shaft 20 may extend vertically between the two brackets 10, or a pair of rotating support shafts may support the guide member 30 between them.
  • the guide member 30 typically includes a guide wheel 31 or a fixed guide channel for the cable or chain to pass through.
  • the guide member 30 can include connecting plates 32 e.g. to connect the guide wheel with the rotating support shaft 20.
  • the guide member is attached to the rotating support shaft(s) and is configured to rotate with the rotating support shaft(s). In this way, the fairlead 1 can rotate around a vertical axis and can guide the line without having an angle in the line.
  • a problem with these moveable fairleads arises where an offshore unit or floating vessel is not anchored and is moving or being moved, and one or more fairleads attached to an exterior of the hull are rotating freely. Freely rotating fairleads can often slam against the floating vessel, causing damage to the vessel and/or the fairlead itself due to the waves and movement of the vessel.
