Definitions

  • the present invention relates to an anchor alignment guide and related methods and associated components including but not limited to anchors for such.
  • An anchor primarily comprises a shank and a fluke.
  • a rode usually an anchor rope with chain proximate the anchor
  • alignment is not normally an issue where the anchor is to be drawn up to the side of the hull because alignment can be dealt with relatively easily by an anchor roller that the shank of the anchor engages as it is pulled up to a retrieved condition.
  • an anchor is to be pulled into a cavity of the hull alignment of the anchor can become desirable where there is a desire to have the anchor pulled onboard in a way where it does not impede the flowpath of water.
  • Alignment of the anchor during the retrieval process may also be desirable in order to ensure that the anchor flukes are positioned, held or controlled, at the appropriate time(s), to avoid their upper ends from hitting the hull of the vessel.
  • the present invention has as an object a wish to arrange for an anchor to be rotated to a condition where it can be pulled into an appropriate cavity or receptacle of a hull of a vessel that addresses at least some of die abovementioned desiderata and/or will at least provide the public with a useful choice.
  • An anchoring system for a ship is shown in FR2720999 .
  • the anchor comprises a shank and a foot, and has a guide zone comprising two guide fins on either side of the shank to position it centrally in the hawsehole.
  • the present invention may be said to be an anchor alignment assembly for engagement by an elongate shank of an anchor, the shank having an outstand which projects transversely to the locus of its rise, the assembly comprising:
  • the surfaces of the guide zone are non-parallel to the elongate axis of the passageway defining member.
  • the guide zone is defined by at least two complementary guide members which provide said surfaces of the guide zone.
  • Each of the two complementary guide members are either or both of:
  • said passage defining member comprises said guide members.
  • bearing members which the side or sides of the shank can bear upon once at least partially inside said passage defining member, and optionally there are at least three or at least five of such bearing members.
  • bearing members are elongate and extend in a direction parallel to the elongate axis of the passageway defining member.
  • the alignment zone is defined by a plurality of spaced apart bearing members which provide said surface of the alignment zone, wherein the side or sides of the shank is/are able to bear on one or more of the bearing members as the shank is drawn through the alignment zone.
  • bearing members are positioned such that the bearing surfaces lie on a circular path, the diameter of the circle being of a size to allow for the shank to be accommodated between bearing members with its elongate axis substantially concentric with the centre of the circle.
  • bearing members are positioned such that the outstand of the shank can be accommodated in the spaces between adjacent bearing members when the shank is drawn through the alignment zone, and optionally the terminal ends of the bearing members are tapered.
  • one or more of said bearing members extends from the alignment zone into the guide zone.
  • the passageway defining member comprises one or more of said bearing members.
  • the assembly further comprises a housing for receiving at least part of a fluke or fluke assembly of the anchor when the anchor is in its fully raised condition.
  • the fluke or fluke assembly is attached in a pivotal manner relative to the shank member and is able to pivot about an axis that is perpendicular to the elongate axis of the shank, and said housing is shaped and adapted to bring the fluke into a rotationally restricted condition where the fluke cannot rotate about said pivot axis when the anchor is in its fully raised condition.
  • the housing houses the anchor when the anchor is in its fully raised condition.
  • said housing has an entrance opening via which the fluke passes as it moves between its fully raised condition and a condition wherein it is not fully raised.
  • the present invention may be said to be an anchor having an elongate shank, the shank having an outs tend which projects transversely to the locus of its rise, said anchor being configured and adapted for engagement with an anchor alignment assembly of the first aspect.
  • said shank has two outstands which project transversely to the locus of the rise of the shank, and which are configured and adapted to engage with the surface or surfaces in the guide zone of the passageway defining member in order to effect rotation of the shank when the shank is not rotationally aligned as required.
  • the anchor comprises a first distal end at which a rode is or can be attached and a second distal end at or near which a fluke or fluke assembly of the anchor is attached, and optionally wherein the fluke is attached in a pivotal manner relative to the shank member about a pivotal axis that is perpendicular to the elongate direction of the shank.
  • the anchor is configured for use with an assembly of the first aspect, and comprises a base (optionally its crown) of or engaged to said fluke, defining the lower end of said anchor, the base being of a shape to close the entrance opening when the anchor is in the fully raised position.
  • the present invention relates to a system allowing the deployment and retrieval of an anchor to be housed in a housing recess or cavity 9 inside the hull 53 of a vessel 54.
  • the anchor 1 may be drawn up into the hull 53 of a vessel 54 on a rode.
  • the hull 53 may include a cavity or recess 9 that is of a shape that is sufficiently large to receive at least part of the anchor 1.
  • the anchor 1 in its fully raised or retrieved condition, does not protrude (or not significantly) outside of the natural hull contour of the hull 53 at where the anchor is stored in its retrieved condition. It is desirable that the flow of water around the hull 53 is not impeded by the anchor when it is stored, and therefore the crown or base region 25 of the anchor may be of a shape and/or contoured to match with the profile of the hull in the region surrounding the cavity.
  • the anchor 1 may be raised by or on a rode and may sit inside a housing 16 as generically shown in broken lines 9 in Figure 1 .
  • the rode usually a chain or cable, will allow the anchor a significant degree of linear, rotational and angular freedom of movement when it is clear of the hull 53. This means that the anchor could be in any rotational or angular position prior to its entry into the cavity.
  • Figure 16a and figure 16b show that the rotational orientation of the anchor may mismatch the orientation that it needs to be in to be received in the housing. This mismatch may be up to 180 degrees for example as shown in Figure 16b . If a mismatch remains, the fluke of the anchor may strike the hull of the vessel.
  • an anchor must be correctly oriented in a rotational condition (ie about its shank axis).
  • an anchor may be swinging and/or laterally displacing as it approaches the vessel. Therefore constraint of the anchor 1 in a horizontal direction may also be desirable before it is fully drawn into the cavity or recess 9.
  • the location of the anchor recess 9 on the vessel 54 will vary from vessel to vessel. There may be only one anchor recess 9 positioned at either the bow or the stern of the vessel 54. Some vessels may have a two anchor system to secure both the bow and stern of the vessel, in which case there may be two recesses 9 positioned as shown in Figures 14 and 15 . Optionally there may be two anchor recesses 9 near the bow region of the hull 53, both aligned along the centreline 59 of the vessel or on each side of the centreline and optionally there may not be a stern anchor. Preferably the recess or recesses 9 will be below the surface of the water 55.
  • the contour of the hull may be substantially parallel to the surface of the water 55 and may also be substantially flat.
  • the crown or bottom surface 25 of an anchor to be stowed at position 56 may be more or less flat and parallel to the axis 57.
  • the anchor may be symmetrical as for example shown in Figures 1 - 13 . In such a case the anchor may have to turn through a maximum angle (about its vertical axis) of 90° from any given starting position in order to be received in an orientation where it will match with the profile of the hull.
  • point 34 on the anchor as shown in Figure 6 and as repeated schematically in Figure 16a can be caused to rotate clockwise or anticlockwise to end up in a rotational orientation that is at greatest, 90° from where it started, in order to locate into its recess 9.
  • the crown or base region 25 of the anchor may need to be asymmetric, for example as shown in Figure 14 .
  • the exterior of the hull 53 with which the base 25 is to become complimentary to may not be normal to the anchor shank, the shank preferably extending vertically in the stored condition. In that case the anchor will have to turn through a maximum of 180° in order to be aligned with a cavity as shown in Figure 16b .
  • the axis 56 is parallel to the centreline of the vessel 58.
  • the recess(es) 9 will be aligned along the centreline of the vessel 58 as shown in Figure 15 , or may be laterally offset from that centreline by some distance.
  • the anchor 1 may have a shank 17 comprising a shank member 3 carrying a crown 25 and a fluke 2 at one end (which may consist of two fluke plates), which is linked by a first shackle 4 and preferably then a second shackle 5 to a rode raisable member 6.
  • a first shackle 4 and preferably then a second shackle 5 to a rode raisable member 6.
  • the fluke 2, and/or the entire crown 25 are pivotally attached to the shank member 3.
  • the rode raisable member 6, in its girth, includes fins or other cross-sectional features 7 meaning it is not in section a body of a rotational generation i.e. it is of a form capable of being guided rotatably reliant on its non-circular form.
  • the anchor 1 is a stockless anchor.
  • the guide members 10 and 11 are preferably tubular or made of rod but may instead be made from other sections. Engagement or contact of the cross sectional feature 7 with the guide members 10 and 11 of the guide passageway 8 drives the rotation of the anchor through the required angle to permit entry of parts of the anchor into the recess 9.
  • the cross sectional feature 7 or the rode raisable region may preferably be a longitudinally extending vane fin or outstand 19.
  • the outstand 19 may be elongate as shown, or may be short and stubby. It may, instead of a vane, be a lug or pin or similar.
  • the shank 17 extends as part of its fabricated form or moulded form to a rode raisable region 21 connectable at 18 by an appropriate opening to a swivel or shackle connection to the rode.
  • the region 21 has a perimeter in transverse section that is not rotationally generated. Indeed that region 21 may include a vane-like outstand 19 from preferably (but not necessarily) a substantially square section that interacts in a manner previously described with the guide.
  • the outstand 19 is preferably longitudinally extending of the shank. It is an outstand that may be at right angles to the pivot axis 20 of the crown 25 or flukes 2 of the anchor which are, in the plane of the drawing of Figure 7 , aligned to the gravity assuming position as a result of the articulation of the flukes 2 relative to the shank member 3.
  • Figures 9 to 13 are the same as Figures 4 to 8 except the vane is shown on both flanks of the shank over the region to help effect the turn.
  • the crown 25 is attached to a long rigid shank 17 having an upper rode raisable region which is not of rotational generation 21. This reduces the likelihood that the anchor 1 will swing up and hit the hull 53 as the anchor is brought proximate to the hull prior to its reception into the cavity 19.
  • a suggested construction for the long rigid shank is as shown in cross section in Figure 18C , wherein a hollow box section 49 is covered by a pipe-like sleeve 50. This construction gives the desired rigidity while minimising the overall weight of the shaft.
  • the cross-sectional feature 7 may be a fin 42.
  • Fin 42 may be of a substantially rectangular section (as shown in Figure 18B ), wedge shaped, or may have some other shape which aids in its smooth engagement with the guide members 10.
  • the shank 17 may be fabricated with an integral fin 42, or may have a recess 44 into which a fin 42 can be slotted. The latter arrangement is preferable because it allows the fin 42 to be removed and replaced as necessary.
  • the fin 42 of the asymmetric anchor may preferably extend outwardly from the shank axis in a plane parallel to that of the pivot axis 20 of the anchor flukes 2.
  • the outstand(s) 19 may extend in a plane perpendicular to the pivot axis. It will be appreciated that the vane/fin position will depend on the desired movement of the anchor and should be selected accordingly.
  • the region of shank member 3 where the vane or fin is provided 21 may be of circular cross section or of an alternative cross section.
  • a circular cross section may be preferable because it allows the shank to be more tightly constrained within the guide passageway 8 to reduce vibration and swinging.
  • the shank member 3 may be of a reduced or reducing diameter or size at its distal end, and may in fact include a significant taper to aid in the initial channelling of the shank into the guide.
  • a guide passageway defining member 8 preferably comprising a converging pairing of guide members 10 and 11 (preferably extending upwardly from the entry zone 24 of the guide passageway 8 in a helix, spiral or corkscrew, or a portion thereof) to ensure that each fin or the like 7 that enters the passageway 8 between a pairing 10 or 11 is thereby guided by contact with a guide surface 29 of a guiding member 10 to a particular disposition that favours the alignment of the anchor 1 to the recess 9.
  • a pointed or wedge-shaped region at the point of convergence 23 will help to ensure that the cross-sectional feature 7 is diverted sideways in one or other direction so as not to get caught on entry to the guide structure 8.
  • the guide passageway defining structure shown in Figures 1B and 2 will effect an anchor rotation of up to 90° in either direction depending on the orientation of the anchor on entry.
  • Each pair of guides 10 and 11 rotationally constrains the fins or each cross sectional feature 7 and hence the shank 17.
  • the rotational constraint increases until, at or near its upper limit of travel 32, the anchor 1 is preferably fully constrained, captured by and between a respective pair of guides 10 and 11, and no further rotation of the anchor can occur. In this rotational orientation the anchor 1 is aligned in its housing 16 and in it stored condition.
  • the degree of rotational constraint is proportional to the distance of travel towards the upper limit 32. Preferably it is directly proportional. Such may be achieved by a helical or spiralled or corkscrewed shaped adaptation of the guides.
  • the guide members 10 and 11 contact a notional cylindrical surface 27 aligned with the elongate axis of the passageway 8, or at least provide a guide surface 29 which contacts with such a notional cylinder 27.
  • the guide members 10 and 11 may be curved tubular members as shown, or a series of straight members which are attached to one another to form a helical guidepath. Alternatively a diagonally cut pipe might provide the required guide surface.
  • the distance between the upper 32 and lower 34 limits of travel of the fin or cross sectional feature 7, and the speed at which the shank 17 is drawn vertically through this distance is such that rotation of the anchor occurs somewhat gradually. If the guide members 10 and 11 force the rotation of the anchor shank 17 too quickly the resistance of the flukes 2 against the water may create undesirably large torsional stresses in the shank member 3.
  • An alternative guide passageway 8 is shown in detail in Figures 19A to 19C and again as part of an anchor pocket assembly in Figure 17A and 17B , is designed to rotate an anchor 1 through a maximum of 180 degrees.
  • the mechanism comprises just one pair of guide members 10 which converge at both their upper and lower ends.
  • the guide members 10 may be supported by apertured plates 39 or alternative structures and in a manner so as to create a passageway through which the shank 17 can move up and down.
  • each guiding member 10 will preferably be of the helical, spiral or corkscrew geometry described in order to effect continuous rotation of the anchor in a single direction through the required angle for alignment with the housing 16, it will be appreciated that other guide geometries could be used to effect different types of motion, for example if the anchor was to be turned in one direction first and then subsequently turned back in the other direction as the shank is raised or lowered.
  • at least the guide surface 29 of each guiding member will make contact with a notional cylinder 27 aligned with the elongate axis of the guide passageway as shown, or will roughly follow such a notional surface.
  • Each pair of guides 10 and 11 may continue in a parallel condition to each other from their region where their convergence terminates thus creating a slot or slots 43 in which the vane, fin or other cross sectional feature can be captured, for example as shown in Figure 3G .
  • a similar slot 43 can also be seen in Figures 17B .
  • a continued lifting of the vane, fin or other cross sectional feature 7 beyond this region will not result in any further anchor rotation but instead a fully rotationally restrained lifting will occur.
  • fin or other cross sectional feature 7 will be retained in the slot 43 to prevent rotation of the anchor while housed.
  • Additional shank support members 15 above the guide passageway, and optionally extending some way down into it help to stabilise the shank member 3 as the anchor 1 is lifted and while it is stowed.
  • the support members 15 may be tubular members which extend some distance up the hawsepipe as shown, or may provide circumferential support to the shank in an alternative way (for example by way of axially spaced rings or circumferentially spaced profiles protruding inwardly of the hawsepipe tube).
  • the recess 9 is defined by, or contains within it, a housing 16 (shown in detail in Figures 20A to 20C ) with a rectangular opening 28.
  • a housing 16 shown in detail in Figures 20A to 20C
  • the housing 16 may be so shaped to snugly receive the anchor 1 when in it in its fully retrieved condition and may have features of shape designed to stabilise the anchor when stowed.
  • the guide members 10 (optionally and 11) will have correctly oriented the anchor 1 so that the anchor fluke 2 is in an alignment that permits their reception into the housing 16.
  • crown 25 and/or fluke 2 may be weighted so that the equilibrium position of the flukes about their pivot axis 20 naturally tends to bring them into more or less planar alignment with the shank member 3 (i.e. into the position shown in Figure 18B ).
  • the channels 33 may be of a different shape or configuration so as to encourage the fluke 2 to adopt, and to retain and stabilise it in, some other equilibrium position, or some other non-equilibrium position.
  • Apertures in the housing 27 and in the hawsepipe 37 allow visual inspection of and physical access to the moving components so that mechanical problems can be easily detected and rectified.
  • the unit is bolt attached rather than welded into the hull so that it can be removed if need be. This reduces the chance that the vessel will need to be dry docked in order to attend to issues with the anchor unit.
  • the shank 17 remains more or less coaxial with the guide passageway 8 as the vane, outstand or fin 7 travels upwardly through the guide members 10 (and optionally 11) so that vane or fin 7 is able to follow the guide surface 29. If the shank member 3 axis becomes either angularly misaligned or transversely misaligned with the elongate axis of the guide passageway 8 (for example as shown in Figure 22 ) then there is a risk that the vane or fin 7 might jump across the guiding member 10 into the non-guide zone 40, where it will eventually be prevented from further vertical movement.
  • the shaft member 3 may become jammed against one of the surrounding passageway defining members 15 and 10 (optionally 11). This could cause damage to the winch, rode, hull or other components of the unit and will prevent retrieval of the anchor.
  • the alignment zone 30 is designed to receive the initial upper part of the shank 17 and to bring it into coaxial alignment with the upper part of the guide passageway 8. For example, it will stop the anchor 1 from swinging and laterally displacing so that the axis of the shank 17 is held substantially vertically and/or coaxial the upper part of the guide passageway 8, prior to the fins 42 entering the upper part of the passageway 8.
  • the alignment zone 30 is preferably bounded by a cylindrical body 45 or some other shaped body having a circular aperture 46 through it.
  • the diameter of the circular aperture 46 must be large enough to permit the non-rotational section of the shank member 21 through it.
  • these bearing members 47 are equispaced.
  • the bearing surfaces 60 must collectively, on their own and/or together with the guide members, provide an effective inner diameter, or a pitch circle diameter which is sufficiently small to bear on the shank member 3 so as to provide a sliding fit engagement.
  • the bottom and top edges of the bearing members 47 may be pointed or tapered so that they act to divert the non-rotational section of the shank 21 into an orientation where it will be able to pass through the alignment region by guiding the outer edge of the non-rotational section (for example the fin or outstand) into one of the gaps 61.
  • the alignment zone 30 causes no or insignificant rotation of the anchor 1 about the axis of the shank 17 as the fins 7 of the anchor pass through the alignment zone.
  • the bearing members 47 may be elongate, and may extend into the guide zone 31 to some extent. This allows the bearing members and guide members to act in concert at the guide zone in a manner to continue to offer lateral bearing to the anchor to stop it swinging.
  • the elongate members that do extend into the guide zone are those which are in a position that, when acting in conjunction with the guide members 10 and 11, will serve to constrain the shank 17 to its correct alignment.
  • the bearing members 47 can only extend into the guide zone in such a way and/or extent as to accommodate the sweep path of the vane, outstand or fin 7 as it rotates while moving through the zone.
  • a configuration suitable for constraining the shank 17 yet still allowing its requisite rotation is shown in Figures 19A to 19C . It is preferable that there will be five bearing members 47as shown, but three members, or more than five members could be used.
