Description

BACKGROUND

[0001] The present invention relates to an anchor intended for anchoring heavy offshore or off-shore objects, such as drilling platforms in the seabed anchoring ground or floating wind turbines. SUMMARY

[0002] Such anchors typically comprise an anchor fluke and a shank connected to the anchor fluke. In a conventional approach, the anchor is fully assembled on shore, and subsequently shipped to the anchoring ground by an anchor laying vessel. Alternatively, the anchor fluke and the shank form a sub-assembly which is brought together on the anchor laying vessel prior to anchor laying. Especially for commissioning of floating wind turbines in off-shore wind farms, economies of scale apply, wherein a large number of anchors are loaded per single shipment to the off-shore commissioning area.

[0003] It is an object of the present invention to provide an anchor which can be shipped and assembled in an efficient manner.

[0004] According to a first aspect, the invention provides an anchor comprising an anchor fluke, a shank connected to the anchor fluke, and an anchor coupling on the shank, the anchor coupling attaching the anchor fluke to an anchor line or chain for installing the anchor in an anchoring ground in a penetrating direction, wherein the shank comprises a left shank leg and a right shank leg, wherein the left shank leg comprises a left base section connected to the anchor fluke and incorporated into a left coupling means for the anchor coupling, and a left interlocking body on the left coupling means and protruding from the left coupling means, and wherein the right shank leg comprises a right base section connected to the anchor fluke and incorporated into a right coupling means for the anchor coupling, and a right interlocking body on the right coupling means and protruding from the right coupling means for interlocking engagement with the left interlocking body by inserting into each other in an insertion direction, wherein the left interlocking body and the right interlocking body have a polygonal cross section transverse to the insertion direction.

[0005] The anchor according to the invention comprises a shank which is pre-assembled by interlocking engagement of a left interlocking body of a left shank leg and a right interlocking body of a right shank leg to form a sub-assembly of the anchor. Since both interlocking bodies have a polygonal cross section, the left shank leg and the right shank leg maintain their mutual position in an efficient manner for handling them relative to the anchor fluke, for example connecting the sub-assembly to the anchor fluke on board of an anchor laying vessel. Since the left shank leg and the right shank leg can be handled separately before assembling the shank, they can be stored in an efficient manner, so that a large number of anchors can be shipped to an off-shore commissioning area.

[0006] In embodiments, the polygonal cross section is a triangular or rectangular cross section.

[0007] In an embodiment, the left interlocking body and the right interlocking body are prismatic in their length in the insertion direction.

[0008] In an embodiment, at least one of the left interlocking body and the right interlocking body comprises a constraining chamber having a polygonal cross-section for constraining the other of the left interlocking body and the right interlocking body inserted therein.

[0009] In an embodiment, the left interlocking body and the right interlocking body are formed from a steel sheet of polygonal configuration.

[0010] In an embodiment, the left interlocking body and the right interlocking body are hollow bodies.

[0011] The above embodiments work well in off-shore and subsea environments.

[0012] In an embodiment, the left interlocking body has a left distal end abutting the right coupling means, or the right interlocking body has a right distal end abutting the left coupling means. The abutment of the left or right distal end thereby defines and ensures a specified distance between the left and right coupling means for the anchor coupling.

[0013] In an embodiment, the left coupling means comprises a left mounting hole and the right coupling means comprises a right mounting hole, wherein the anchor comprises a tensioning rod or a tensioning bolt extending through the left and right mounting holes and holding the left and right interlocking bodies inserted into each other.

[0014] In an embodiment thereof, the tensioning rod or bolt extends through the left and right interlocking bodies. The sub-assembly of left and right shank legs can be fixed to each other at the location of the interlocking bodies.

[0015] In an embodiment, the insertion direction extends transversely to the penetration direction.

[0016] In an embodiment, the insertion direction extends transversely to a longitudinal symmetry plane of the anchor.

[0017] In an embodiment, the left and right base sections diverge from the respective left and right coupling means towards the anchor fluke.

[0018] In an embodiment, the fitted left and right interlocking bodies extend spaced apart from the anchor coupling between the left and right coupling means.

[0019] In an embodiment, the anchor coupling comprises a shackle articulably connected with the left and right coupling means.

[0020] In embodiments, the left base section is formed with a left plate section having a straight left base main plane from the left coupling device to the fluke, and the right base section is formed with a right plate section having a straight right base main plane from the right coupling device to the fluke. The shank legs can thus be stored in an efficient manner, for example in a rack or stack, with the base main planes parallel to each other. In this manner, a large number of anchors can be shipped to an offshore commissioning area. For example, a plurality of identical left fluke legs can be stored in a rack, a plurality of identical right fluke legs can be stored in a rack, or groups of left and right fluke legs can be positioned relative to each other such that the base main planes are parallel to each other and eventually in contact with each other over a substantial portion of their facing surfaces.

[0021] In embodiments thereof, the left base main plane and the right base main plane extend parallel to each other along the fluke.

[0022] In embodiments, the left plate section merges into the left coupling device over a transition angle, and the right plate section merges into the right coupling device over the same transition angle.

[0023] In embodiments thereof, the left plate section merges into the left coupling device along a left transition line over the transition angle, and the right plate section merges into the right coupling device along a right transition line over the same transition angle, wherein the left transition line and the right transition line extend parallel to each other.

[0024] In embodiments, the anchor comprises a left fluke connection between the left base section and the fluke, and a right fluke connection between the right base section and the fluke, through which the subassembly can be connected to the fluke on the anchor handling vessel.

[0025] In embodiments thereof, the left fluke connection comprises at least one left mounting lug on the left base section, at least one left insertion slot in the fluke for insertion of the at least one left mounting lug, and at least one left mounting pin for insertion through the at least one left mounting lug and the fluke, and the right fluke connection comprises at least one right mounting lug on the right base section, at least one right insertion slot in the fluke for insertion of the at least one right mounting lug, and at least one right mounting pin for insertion through the at least one right mounting lug and the fluke.

[0026] In embodiments, the fluke comprises a central penetration plate extending between the left shank leg and the right shank leg, and a left outer penetration plate and a right outer penetration plate, the left outer penetration plate and the right outer penetration plate being connected to the central penetration plate at the respective left shank leg and right shank leg and pointing downward from the central penetration plate at an angle of 10-20 degrees relative to the central penetration plate away from the anchor link.

[0027] In embodiments, the left transition line and the right transition line extend parallel to the central penetration plate.

[0028] According to a second aspect, the invention provides a method for assembling an anchor, wherein the anchor comprises a fluke, a shank connected to the fluke, and an anchor link on the shank, the anchor link attaching the fluke to an anchor line or anchor chain for installing the anchor in an anchoring ground in a penetration direction, wherein the shank comprises a left shank leg and a right shank leg, wherein the left shank leg comprises a left base section connected to the fluke and incorporated into a left link device for the anchor link, and a left interlocking body on the left link device and protruding from the left link device, and wherein the right shank leg comprises a right base section connected to the fluke and incorporated into a right link device for the anchor link, and a right interlocking body on the right link device and protruding from the right link device for interlocking engagement with the left interlocking body by inserting into each other in an insertion direction, wherein the left interlocking body and the right interlocking body have a polygonal cross section transverse to the insertion direction, wherein the method comprises the steps of moving the left shank leg and the right shank leg towards each other in the insertion direction so as to interlock the left interlocking body and the right interlocking body, and installing the left shank leg and the right shank leg to the fluke, wherein the interlocked left interlocking body and right interlocking body maintain the mutual position of the left shank leg and the right shank leg. The method according to the invention has the advantages as described before.

[0029] The various aspects and features described and illustrated in the specification can be applied individually, wherever possible. These individual aspects, in particular the aspects and features described in the attached dependent claims, can be the subject of a divisional patent application. BRIEF DESCRIPTION OF DRAWINGS

[0031] Figures 1A-1D An anchor 1 according to an embodiment of the present application is shown. The anchor 1 is intended for anchoring heavy offshore or off-shore objects, such as a drilling platform or a floating wind turbine in a seabed anchoring ground, for long term use, possibly for many years. The anchor 1 has a typical self weight of 1-50 tons. The anchoring ground can consist of sand, clay, mud or a combination thereof.

[0032] The anchor 1 comprises a fluke 10 and a shank 70, which is inclined forwardly relative to the fluke 10 and is provided at its end with an anchor coupling, in this embodiment a shackle 100, by which the anchor 1 is connected to an anchor line or chain. The anchor 1 is generally symmetrical relative to its longitudinal symmetry plane M, as shown in Figure 1C except for some special features described in detail below. The anchor 1 is formed to be introduced into the anchoring ground in a forward penetration direction P, which is generally parallel to the longitudinal symmetry plane M of the anchor 1.

[0033] The fluke 10 is made using steel plate members connected to each other by welding. As shown in Figures 1A-1CAs best shown, the anchor claw 10 includes a straight center penetrating plate 11 extending transversely to the longitudinal plane of symmetry M. The center penetrating plate 11 includes a straight left edge 12 and a straight right edge 13, which are parallel to each other and extend at the same distance from the longitudinal plane of symmetry M.

[0035] Anchor claw 10 is included below the corresponding left and right edges 12 and 13 of the central penetrating plate 11 and along their straight left and right beam plates 40 and 41. The left and right beam plates 40 and 41 have corresponding straight left bottom edges 42 and 43 extending parallel to the longitudinal plane of symmetry M. The left and right bottom edges 42 and 43 merge via corresponding straight left and right bottom penetrating edges 44 and 45 to form left and right penetrating tips 46 and 47, which can be locally formed of hardened steel. The left and right penetrating tips 46 and 47 protrude from left and right penetrating plate points 24 and 25 in the penetrating direction P. Figure 1C As shown in the best example, the left beam plate 40 and the right beam plate 41 form a connection angle D of 10-25 degrees with respect to the longitudinal plane of symmetry M, which is 18 degrees in this particular example, as described below.

[0036] like Figure 2A As shown in the optimal configuration, the anchor claw 10 includes a left front insertion slot 50 and a left rear insertion slot 51 through the left edge 12 of the central penetrating plate 11, which provide access to the outer side of the left beam plate 40. Figure 2AAs shown in the optimal configuration, the anchor claw 10 includes a right front insertion slot 52 and a right rear insertion slot 53 through the right edge 13 of the central penetrating plate 11, providing passage to the outer side of the right beam plate 41.

The left beam plate 40 has a left mounting hole 56 below the left insertion slots 50, 51, and the right beam plate 41 has a right mounting hole 57 below the right insertion slots 52, 53.

[0037] Anchor claw 10 includes a rear penetrating plate 60 that merges into the central rear edge 17 and the left and right rear edges 28 and 29. The rear penetrating plate 60 hangs obliquely downward from the central penetrating plate 11 and includes a straight lower left penetrating edge 61 and a straight lower right penetrating edge 62 that extend at the same angle of inclination relative to the longitudinal plane of symmetry M and extend forward in a V-shape from the rear ends of the left and right rear edges 28 and 29 to merge with each other in the longitudinal plane of symmetry M.

[0038] The handle 70 is made of steel plate members that are welded together. The handle 70 includes a left handle leg 71 and a right handle leg 72, which are connected to each other and attached to the anchor claw 10, as described below.

[0039] like Figure 1A , Figure 1C and Figure 2A As best shown, the left handle leg 71 includes a left base section 73 having a straight left base main plane Q on its entire surface; a left hook ring mounting plate 81 having a left hook ring mounting eye 83 and a left hook ring main plate main plane T, the left hook ring main plate main plane T being along a straight left transition line 65 forming a transition angle U with the left base main plane Q of the left base section 73; and a left interlocking body 85 extending transversely to and protruding from the left hook ring mounting plate 81 in the longitudinal plane of symmetry M. The left hook ring mounting plate 81 with the left hook ring mounting eye 83 forms a left connecting device for the hook ring 100. In this embodiment, the left handle leg 71 includes a left front mounting lug 77 with mounting eye 78 and a left rear mounting lug 79 spaced apart therefrom having mounting eye 80. Left front mounting lug 77 and left rear mounting lug 79 project parallel to each other from the left base section 73, their principal planes both lying in the left base principal plane Q of the left base section 73. Left handle leg 71 includes a concave curved left through edge 75 that extends over the entire length between the left hook mounting plate 81 and the left front mounting lug 77.

[0040] The right shank leg 72 includes a right base section 74 having a straight right base major plane R over its entire surface; a right carabiner mounting plate 82 having right carabiner mounting eyelets 84 and having a straight right transition line 66 at the same transition angle U to the right base major plane R of the right base section 74, the right carabiner mounting plate 82 having a right carabiner main plate major plane S; and a right interlock 86 projecting from the right carabiner mounting plate 82 transverse to the longitudinal plane of symmetry M. The right carabiner mounting plate 82 with the right carabiner mounting eyelets 84 forms a right coupling device for the carabiner 100. In this embodiment, the right shank leg 72 includes a right front mounting lug 87 having a mounting eyelet 88 and a right rear mounting lug 89 spaced apart therefrom having a mounting eyelet 90. The right front mounting lug 87 and the right rear mounting lug 89 project parallel to each other from the right base section 74, their major planes both being in the right base major plane R of the right base section 74. The right shank leg 72 includes a concavely curved right penetration edge 76 extending over the entire length between the right carabiner mounting plate 82 and the right front mounting lug 87.

[0041] The left front mounting lug 77, the left rear mounting lug 79, the left front insertion slot 50, the left rear insertion slot 51, and the left beam plate 40 form part of the left fluke connection of the anchor 1. The right front mounting lug 87, the right rear mounting lug 89, the right front insertion slot 52, the right rear insertion slot 53, and the right beam plate 41 form part of the right fluke connection of the anchor 1.

[0042] The left and right carabiner mounting plates 81 and 82 extend parallel to each other and to the longitudinal symmetry plane M. In departure from the symmetry of the anchor 1 about the longitudinal symmetry plane M, the left and right interlocking bodies 85 and 86 are different from each other. Both the left and right interlocking bodies 85 and 86 are prismatic and have the same polygonal or non-circular configuration of steel walls to form a polygonal or non-circular cross section that is constant in shape and size over the length from their respective left and right carabiner mounting plates 81 and 82 up to their distal ends. In this embodiment, both the left and right interlocking bodies 85 and 86 have a triangular cross section. The left and right interlocking bodies 85 and 86 are hollow and mate with each other in the direction of insertion G transverse to the longitudinal symmetry plane M so as to form a shape lock that keeps the left and right shank legs 71 and 72 aligned. In this embodiment, the hollow right interlocking body 86 defines a confinement chamber 95 for the insertion and confinement of the left interlocking body 85 in a shape-closed manner to prevent mutual rotation about the direction of insertion G. In this embodiment, only one of the left and right interlocking bodies 85 and 86 defines the distance between the left and right carabiner mounting plates 81 and 82 with its length. In this embodiment, the right interlocking body 86 enclosed in the left interlocking body 85 defines the distance between the left and right carabiner mounting plates 81 and 82. The left and right interlocking bodies 85 and 86 are held in engagement by a tensioning bolt 93 that extends through a left mounting hole 91 in the left carabiner mounting plate 81, through the hollow left and right interlocking bodies 85 and 86, and through a right mounting hole 92 in the right carabiner mounting plate 82, and is tightened with a nut 94.

[0043] The carabiner 100 is made of steel and comprises a D-shaped bow 101 incorporated in a left end eyelet 102 and a right end eyelet 103, with the carabiner 100 enclosed between the left and right carabiner mounting plates 81 and 82. A carabiner bolt 104 with an end nut 105 extends through the right carabiner mounting eyelet 84, the right end eyelet 103, the left end eyelet 102, and the left carabiner mounting eyelet 83 to allow the D-shaped bow 101 to rotate about the carabiner bolt 104.

[0044] As shown in Figure 3A and Figure 3B A plurality of identical anchors 10 can be effectively stacked on each other to form an anchor stack 130. The anchors 10 are opened from below, with the anchors 10 partially nested in each other, while the lower left and right edges 42 and 43 of the upper anchors 10 are located alongside the central penetration plate 11 and on the respective straight left and right outer penetration plates 20 and 21 of the lower anchors 10 in the anchor stack 130 due to the coupling angle D. The central penetration plate 11 of the lower anchors 10 is compactly located between the left and right beam plates 40 and 41.

[0045] As shown in Figure 4A and Figure 4BAs shown, the left handle leg 71 and the right handle leg 72 can be effectively stacked on top of each other to form a material in the form of a handle component stack 140, wherein in the projection transverse to the parallel extending left base principal plane Q and right base principal plane R, the left base segment 73 and the right base segment 74 overlap on most of their surfaces, i.e., quantitatively overlap each other on at least 60% of their surfaces. In the layer of left base segment 73 stacked on the right base segment 74, the left front mounting lug 77 and the right front mounting lug 87 form the outermost portions in the projection transverse to the parallel extending left base principal plane Q and right base principal plane R. Due to the curvature along the left penetrating edge 75 and the right penetrating edge 76, the left hook-and-loop mounting plate 81 and the right hook-and-loop mounting plate 82 are positioned in opposite directions outside the projection transverse to the parallel extending left base principal plane Q and right base principal plane R. The left hook-and-loop mounting plate 81 and the right hook-and-loop mounting plate 82 both stand upright at an upward angle from their respective left base main plane Q and right base main plane R, and are adjacent to each other in the adjacent areas 141 within their respective left base sections 73 and right base sections 74. The left interlocking body 85 and the right interlocking body 86 protrude in the same direction and from their respective left hook-and-loop mounting plates 81 and 82 toward the left base main plane Q and right base main plane R. The right handle leg 72 and its longer right interlocking body 86 are stacked above the left handle leg 71, and the distal end of the right hook-and-loop mounting plate 82 defines the maximum height of the handle component stack 140. Alternatively, the left handle leg 71 and the right handle leg 72 can be effectively stacked on top of each other to form a handle component stack, wherein the left base segment 73 and the right base segment 74 are completely stacked on top of each other, wherein the left base principal plane Q and the right base principal plane R are parallel to each other, and wherein the left hook-and-loop mounting plate 81 and the right hook-and-loop mounting plate 82 are tilted upright and far apart from each other in opposite directions. In this alternative handle component stack, the left base segment 73 and the right base segment 74 completely overlap each other in projections transverse to the parallel extending left base principal plane Q and right base principal plane R.

[0046] Alternatively, such as Figure 5A and Figure 5B As shown, multiple identical left handle legs 71 can be positioned such that the left base main plane Q is parallel to each other, wherein the left interlocking body 85 can abut the left hook mounting plate 81 of the adjacent left handle leg 71. In the same manner, as... Figure 6A and Figure 6B As shown, multiple identical right handle legs 72 can be positioned such that the right base main plane R is parallel to each other, wherein the right interlock body 86 can abut the right hook mounting plate 82 of the adjacent right handle leg 72. The parallel positioning of the base main planes Q and R allows for compact mounting of the handle legs 71 and 72.

[0047] The assembly of the anchor 1 from its components is shown in Fig. 2. The left and right shank leg 71, 72 are not stacked and are positioned relative to each other such that the left interlock 85 can be fully inserted into the right interlock 86 in the insertion direction G. Subsequently, the left and right mounting lugs 77, 79, 87, 89 are inserted in the respective left and right insertion slots 50, 51, 52, 53 in the direction H, wherein the tolerances allow for a mutual movement of the left and right shank leg 71, 72 to facilitate the insertion. After the insertion, the mounting eyelets 78, 80 of the left shank leg 71 become aligned with the left mounting holes 56 in the left beam plate 40 and the mounting eyelets 88, 90 of the right shank leg 72 become aligned with the right mounting holes 57 in the right beam plate 41, receiving therein a mounting pin or bolt 58. In the assembled state, the left base main plane Q of the left base section 73 and the right base main plane R of the right base section 74 both extend at a divergence angle E relative to the longitudinal symmetry plane M, wherein the divergence angle E is equal to the coupling angle D.

[0048] It is to be understood that the inclusion of the above description is to illustrate the operation of the preferred embodiment and is not intended to limit the scope of the present application. From the above discussion, many variations will be apparent to those skilled in the art that would be encompassed by the scope of the present application.
