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 moveable fairlead comprises a pair of brackets 10, a rotating support shaft 20 and a guide member 30.
  • 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 axis and can guide the line without having an angle in the line. A similar arrangement to this is described in CN107380349 .
  • 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.
  • the present invention aims to address these problems in the state of the art.
  • a moveable fairlead with a braking unit for use on a floating vessel according to claim 1.
  • a method of retrofitting a braking unit to a moveable fairlead on a floating vessel according to claim 11.
  • the present invention relates to a braking unit for attachment to a moveable fairlead, and a method of retrofitting the braking unit to a moveable fairlead.
  • the braking unit reduces movement of the fairlead by bringing one or more braking pads into contact with a stopper plate.
  • FIG. 2 of the accompanying drawings shows a braking unit 100 for a moveable fairlead 1 on a floating vessel according to an embodiment.
  • the braking unit 100 comprises a stopper plate 110, one or more braking pads 120 and a braking actuator 130.
  • the stopper plate 110 is configured for coupling to a rotating support shaft of the moveable fairlead 1.
  • the stopper plate 110 is configured to be coupled in a position where an axis of the rotating support shaft is normal to the stopper plate 110.
  • the stopper plate is of part-disc shape.
  • the braking pads 120 are configured to resist a rotational movement of the stopper plate 110.
  • the braking actuator 130 is configured to move the braking pads 120 into a braking position where the braking pads 120 are in contact with the stopper plate 110.
  • the braking unit 100 can resist swinging of a moveable fairlead 1 which has the potential to cause damage to the floating vessel or the fairlead 1 itself.
  • the braking unit 100 can be provided in a modular unit which can be retrofitted to an existing fairlead 1 in situ on a floating vessel.
  • the braking unit 100 can be attached or retrofitted to any form of floating vessel, e.g. a ship or floating platform.
  • the braking unit 100 can be made compatible with any of the large variety of moveable fairleads used on such floating vessels.
  • the braking unit 100 can be attached to a fairlead 1 with a guide wheel or guide channel, with or without connecting side plates, and with a single support shaft or a pair of support shafts supporting a guide member in between.
  • the braking unit 100 can be made compatible with any other variation in form or size of moveable fairlead 1.
  • Figure 3 shows an external view of the braking unit 100 and the moveable fairlead 1.
  • the stopper plate 110 may be configured to directly attach to the rotating support shaft.
  • the stopper plate 110 may be configured to attach to a guide member which is attached to the rotating support shaft and configured to rotate with the rotating support shaft.
  • the stopper plate 110 may be configured to attach to a connecting side plate which is coupled to the rotating support shaft, or supported between two rotating support shafts, and supports a guide wheel.
  • the stopper plate 110 may be shaped for attachment to the moveable fairlead 1.
  • the stopper plate 110 may include a notch configured to fit around the rotating support shaft or any other rotating element of the moveable fairlead 1.
  • the stopper plate 110 may be formed from steel, or any material suitable for marine construction.
  • the stopper plate 110 may have a semi-circular form with a straight edge and a semi-circular edge.
  • the stopper plate 110 may be configured to be coupled to the rotating support shaft at a mid-point of the straight edge.
  • the stopper plate 110 can be directly attached at a central point of rotation to a rotating element of the moveable fairlead 1. As the stopper plate 110 is rotated by movement of the moveable fairlead 1, the stopper plate 110 can pass the one or more braking pads 120 in a semi-circular arc, providing a consistent surface for braking the fairlead 1.
  • the stopper plate 110 may be formed from any sector of a circle e.g. subtending an angle of more or less than 180, and configured to be attached at the centre point.
  • the stopper plate 110 may include a curved edge passing substantially through the central point.
  • the semi-circular edge may be smooth or may be formed or shaped as required.
  • the stopper plate 110 may be configured to extend through a socket 140 formed in a hull of the floating vessel.

  • a portion of the stopper plate 110 furthest from an attachment point of the stopper plate 110 may extend through the socket 140, i.e. a portion of the semicircular edge may be inside the hull of the floating vessel.
  • the braking pads 120 may be arranged in pairs above and below the stopper plate 110.
  • the braking pads 120 may be formed from steel, or any material suitable for marine construction.
  • the material of the stopper plate 110 and the braking pads 120 may be selected to avoid galvanic pairs, to prevent excess corrosion.
  • the socket 140 may be rectangular, as shown. The size of the socket 140 may be approximately the same as the portion of the stopper plate 110 extending through. In some examples, the socket 140 may be sized such that the full stopper plate 110 will not pass through. Alternatively, the socket 140 may be any shape or size which allows at least a portion of the plate to pass through. In some examples, the socket 140 may be already present on the hull, e.g. a maintenance hatch for the fairlead 1, or the socket 140 may be cut into the fairlead 1 in order to retrofit the braking unit 100.
  • the socket 140 may include a seal, e.g. a rubber seal arranged to fit tightly against the stopper plate 110 and allow rotational movement while preventing water from entering the hull.
  • the braking unit 100 may be separately sealed to prevent the ingress of water from inside the socket 140.
  • the braking unit 100 can be protected from seawater.
  • the socket 140 and/or braking unit 100 is sealed or substantially sealed, the braking unit 100 can be isolated from seawater. In this way moving/mechanical parts of the braking unit 100 can be protected from corrosion.
  • the braking unit 100 can be accessed more easily from the interior of the floating vessel, to maintain or repair components of the braking unit 100.
  • the braking unit 100 may be positioned on an exterior of the floating vessel e.g. where it is not possible to provide a socket 140 in the hull of the floating vessel.

  • the enclosure 150 may be arranged to receive the stopper plate 110 within.
  • the braking pads 120 may be embedded in an upper and/or lower wall of the enclosure 150.

  • the enclosure 150 may be a rectangular box shape which is open at one side.
  • the open side of the enclosure 150 may be configured to attach to an interior side of the hull of the floating vessel, with the socket 140 within the open side. In this way, the interior of the enclosure 150 may be open to the exterior of the floating vessel.
  • the enclosure 150 may include one or more openings in an upper and/or lower wall of the enclosure 150. Each opening may be configured to receive one of the one or more braking pads 120.

  • the braking actuator 130 may include one or more hydraulic cylinders. In some examples, the braking actuator 130 may include one or more hydraulic cylinders for each of the one or more braking pads 120, or a hydraulic cylinder may be connected to multiple braking pads 120.
  • the braking actuator 130 may include a shoe or shell configured to hold the braking pads 120. The shoe or shell may be connected to the hydraulic cylinder or any other form of actuator.
  • the braking unit 100 is capable of exerting a sufficiently large braking force on the stopper plate.
