    BE2018 / 5541 DEVICE AND METHOD FOR ESTABLISHING A TUBULAR ELEMENT WITH A LENGTH DIRECTION FROM A SUPPORT FLAT ON AN END OF A TIP
    TECHNICAL FIELD OF THE INVENTION
    The invention relates to a device and method for erecting a tubular element with a longitudinal direction from a supporting surface at an end. The invention relates in particular to a device and method for erecting from the working deck of a vessel at one end a foundation pile of a wind turbine to be placed on an underwater bottom and / or a wind turbine tower to be placed on an already installed foundation. The foundation can in this case comprise a so-called monopile foundation or a so-called jacket foundation.
    BACKGROUND OF THE INVENTION
    The invention will be explained with reference to an offshore wind turbine. However, this reference does not mean that the invention is limited thereto, and the device and method may equally well be used to place any other tubular element on any surface. For example, it is possible to apply the invention in the context of providing other offshore foundation structures, jetties, radar and other towers, and also for onshore applications.
    Foundation piles of an offshore wind turbine in many cases include hollow tubular elements of steel or concrete that can have a length of more than 100 m, a diameter of 6 m and more, and a weight that can go up to 800 - 2300 tons and more. Foundations for wind turbines are also becoming heavier because wind turbines are constantly being scaled up. Because of the increasingly robust foundations, these are increasingly difficult to handle.
    A known method for placing a foundation pile on an underwater bottom comprises receiving the foundation pile from a vessel with a lifting means such as a crane and lowering it to or on the underwater bottom
    BE2018 / 5541 of the foundation pile. The foundation pile is then disconnected from the lifting means.
    The inclusion of a foundation pile is a delicate operation, among other things because it can easily cause damage to the foundation pile. It should be borne in mind that the foundation pile can protrude over a large distance over the deck of a vessel, and that distances between a pick-up device and the foundation pile are generally very small with respect to, for example, the diameter of the foundation pile, so that undesired contact between a pick-up device is easily achieved. and wall parts of the foundation pile. Moreover, various operators are active in the operation of the tools used, such as the crane, winches provided on the deck of the vessel, and the like.
    A drawback of the known device is that the risk of damage to a tubular element to be erected, such as a foundation pile, is high. The known device can also perform its work only when the sea is relatively calm, and is generally only suitable for a limited diameter range of a tubular element.
    SUMMARY OF THE INVENTION
    It is therefore an object of the present invention to provide a device and method for erecting a tubular element with a longitudinal direction from a supporting surface at an end which at least partially helps to solve the above-mentioned disadvantages of the prior art. In particular, the invention aims to provide an improved device and method for erecting at one end a tubular element with a longitudinal direction, in particular a foundation pile of a wind turbine to be placed on an underwater bottom, and / or to be placed on a foundation already installed. wind turbine tower.
    To this end, a device is provided according to the invention, according to claim 1. The device comprises a support beam running substantially parallel to the supporting surface and connected to the supporting surface in a supporting point, the supporting beam guiding a coupling gear adapted for coupling to a wall part of a supporting member. end of the tubular element, and wherein the coupling harness with respect to the support surface
    BE2018 / 5541 can be moved with the support beam from a free position to a coupling position in which the tubular element end is engaged by the coupling harness.
    Because the supporting beam is connected to the supporting surface in a supporting point, and a tubular element to be erected is positioned in use in the region of the supporting beam, directly or indirectly on the supporting surface, in the region of the supporting beam, the tubular element and the supporting beam provided with the coupling gear substantially the same movements as the supporting surface. As a result, the coupling harness can be coupled to one end of the tubular element without much risk of damage. This is done by moving the coupling harness from a free position to a coupling position in which the tubular element end can be engaged by the coupling harness.
    The device thus ensures that a tubular element with less chance of damage can be picked up and erected, in particular from a surging vessel.
    In an embodiment of the invention, a device is provided wherein the support beam around the support point and the coupling gear around the support beam are rotatable about an axis of rotation extending perpendicular to the support surface. With this embodiment, the positioning of the coupling gear with respect to the end to be gripped is facilitated.
    A further improved device has, according to an embodiment, been provided with a coupling tool translatable along the support beam.
    Another embodiment offers a device in which these two supporting beams running substantially parallel to the supporting surface are connected to the supporting surface in supporting points and which are placed at such a distance from each other that a tubular element to be erected can be positioned between and parallel to the supporting beams. wherein the support beams guide the coupling gear, and wherein the coupling gear is translatable relative to the support surface in the longitudinal direction of a tubular element positioned between the support beams from the free position to the coupling position. It is also possible to provide a device in which it comprises only one supporting beam running parallel to the supporting surface and connected to the supporting surface in supporting points. Such a support beam is then preferably heavier
    BE2018 / 5541 designed to guide the coupling gear.
    In the context of the present description of the invention, the term "substantially or substantially" means more than 80% of the declared value or characteristic, more preferably more than 85%, even more preferably more than 90%, and also 100%.
    Another aspect of the invention relates to a method for erecting a tubular element with a longitudinal direction from a supporting surface at an end. The method comprises the steps of positioning a tubular element to be erected parallel to the supporting surface, namely in the region of a supporting beam running substantially parallel to the supporting surface and connected in a supporting point to the supporting surface; moving a coupling harness under guidance of the support beam relative to the supporting surface, which coupling device is adapted for coupling to a wall part of an end of the tubular element, wherein the coupling harness is moved from a free position to a coupling position; and engaging the tubular element end by the coupling harness for coupling.
    The manner in which the coupling harness can be moved relative to the supporting surface to the coupling position can in principle be chosen freely. Thus, according to an embodiment of the device, it is possible to provide support beams which are translatably connected to the support points in the longitudinal direction of a tubular element positioned between the support beams. A coupling device guided by the support beams can then be shifted by shifting the support beams. The coupling device can in this case be fixedly connected to the support beams.
    In another embodiment, a device is used in which the support beams are fixedly connected to the support points. In one embodiment the coupling harness can in this case be translatably connected to the support beams.
    In yet another embodiment, the support beam is rotated around the support point, and the coupling gear around the support beam is rotated about a rotation axis extending perpendicular to the support surface. In this case, the coupling harness can also be translated along the support beam if desired.
    BE2018 / 5541
    The device is particularly suitable for erecting tubular elements of relatively large size, for example with diameters of 6 m and more, and with lengths that can amount to 80 m and more. To this end, an embodiment provides a device wherein the coupling device comprises a lifting device for connection to a lifting device such as a crane. In this embodiment, a tubular element coupled to the coupling device can be received and raised on the lifting device of the coupling device. To this end, in another embodiment, the device may further comprise a lifting means supported by the supporting surface for receiving the coupling device on the lifting device. A suitable lifting means comprises, for example, a crane of any known type.
    The supporting surface for the lifting means can comprise a bottom, soil, a concrete slab, and so on. The device is particularly suitable for erecting tubular elements offshore, for which purpose the supporting surface comprises a working deck of a floating vessel. In this embodiment the device is manipulated from a working deck of a vessel, for example a jack-up platform. The invention is most suitable when the supporting surface comprises a working deck of a floating vessel suitable for lifting heavy objects.
    The coupling harness and / or the support beam (s) can in principle be made movable, rotatable and / or translatable in any way known to those skilled in the art with respect to the support surface. A practical embodiment provides a device in which the coupling gear and / or the supporting beams are displaceable, rotatable and / or translatable relative to the supporting surface by means of hydraulic piston cylinders extending between the coupling gear and / or the supporting beams, and the supporting surface. Other means for translating the coupling gear and / or the support beam (s) relative to the support surface may comprise a toothed rod and gear system, or a winch system, or combinations of such means.
    The support beam (s) according to the invention are preferably relatively light and strong, at least for being able to jointly guide and / or support the coupling device. A suitable embodiment comprises a device wherein the support beam (s) has a lattice structure
    BE2018 / 5541. The support point connected to the support surface can also be designed as a framework structure if desired.
    An embodiment in which the support beam (s) are arranged to substantially only support the coupling harness is preferred because this embodiment is as light as possible and requires a minimum of material. The aids, such as the means for translating the support beams, can also be of relatively light design. In such an embodiment the coupling harness can be brought to the clamping position under the guidance of and / or supported by the supporting beams. Once coupled to a tubular element, the weight of said element can, if desired, be taken up by a lifting means connected to the coupling gear and / or tubular element.
    The invented device can in principle be used in combination with any suitable coupling device for a tubular element. Such coupling devices are adapted to engage one end of a tubular element and then raise said element with a suitable lifting means at the end. The coupling between the coupling harness and the element end can be based on any coupling principle, and can be effected, for example, by friction coupling and / or flange coupling.
    A preferred embodiment of the device relates to a coupling rig that comprises a cross-shaped support structure of mutually coupled beams; a lifting member pivotally connected to the support structure for connection to a lifting means such as a crane; and clamping members slidable along the beams from a free position to a clamping position for coupling to a wall part of the end of the tubular element in the clamping position, in which clamping position the beams extend substantially transversely to the longitudinal direction of the tubular element.
    In one embodiment of the invention, the clamping members are slidable from the free position to a clamping position farther from a center of the support structure than the free position for coupling to an internal wall part of a hollow end of the tubular element. By providing the possibility of shifting the clamping members from the free position to the clamping position, tubular elements of varying diameter can be engaged and erected without the device having to be adapted for this purpose. The decor makes it in the
    BE2018 / 5541 particularly possible to erect tubular elements with relatively large diameters.
    By relatively large diameter is meant in the context of the present application a diameter of greater than 6 m, more preferably of greater than 7 m, even more preferably of greater than 8 m, even more preferably of greater than 9 m, and most preferably greater than 10 m.
    The coupling of the slidable clamping members with a wall part of the tubular element can in principle comprise any type of coupling. Suitable couplings include, for example, a friction coupling or a flange coupling, or a combination of both. A friction coupling is based on the generation of frictional forces between surfaces of a clamping member and a respective wall part on which the clamping member engages by pressing both surfaces against each other. A flange coupling can be based on a bolt connection between flanges of a clamping member and a respective wall part on which the clamping member engages. A better flange coupling can be obtained by designing the clamping members such that they can slide under a flange of the tubular element so that a mechanical flange coupling is created.
    During the erection of the element, in one embodiment, a jacket part of the element with a suitable clamping voltage can be engaged by the clamping members. Because, for example, the clamping members, when the device is introduced into a hollow end of the tubular element, are relatively close to the center of the cross-shaped support structure, the application of damage becomes less likely. It also becomes possible, if desired, to work at a higher sea going than is possible with the method according to the prior art.
    Yet another embodiment provides a device that further comprises support members for a wall portion of the tubular member connected to the beam. Such members may be helpful in supporting a tubular member during its erection against gravity. The supporting members are preferably used for erecting tubular elements with a relatively large diameter, and are instrumental in avoiding overloading of the tubular element.
    BE2018 / 5541 The clamping members of the support structure can in principle be located on an upper or lower side, or both sides of the support structure. A practical embodiment relates to a device in which the lifting member is located on an upper side of the cross-shaped support structure for connection to the lifting means, and the clamping members are slidable along a bottom side of the supporting structure.
    The clamping members of the support structure can in principle be slidable along the beams of the support structure in any manner known to those skilled in the art. A relatively maintenance-insensitive embodiment relates to a device in which the clamping members are slidable by means of a hydraulic piston cylinder extending between a clamping member and the support structure.
    Because the device aims at at least partially preventing damage to tubular elements to be erected at sea, another embodiment of the invention is formed by a device in which surfaces which may come into contact with wall parts of the tubular element are provided with shock-absorbing elements such as rubber lining . These surfaces may, for example, be end surfaces of the clamping members, of the supporting members and / or of the supporting structure in some embodiments.
    The advantages of the device according to the invention are particularly expressed in an embodiment in which the tubular element concerns a foundation pile of a wind turbine and / or a wind turbine tower to be placed on an already installed foundation.
    With the device, a tubular element with a longitudinal direction at an end thereof can be erected with a reduced risk of damage. A tubular element to be erected is hereby positioned substantially parallel to the supporting surface between two supporting beams extending substantially parallel to the supporting surface and connected in supporting points to the supporting surface; a coupling rig under the guidance of the support beams relative to the support surface in the longitudinal direction of the tubular element positioned between the support beams translated from a free position to a coupling position; and the tubular element end engaged by the coupling harness for coupling.
    BE2018 / 5541
    The method further preferably comprises receiving the coupling harness with the tubular element end coupled thereto for erection with a lifting means; and, optionally, lifting the tubular member coupled to the device to a desired position. Afterwards the coupling harness can be disconnected from the tubular element end.
    Another aspect of the invention relates to an assembly of a device according to one of the described embodiments and a tubular element coupled to such a device.
    The embodiments of the invention described in this patent application can be combined into any possible combination of these embodiments, and each embodiment separately can be the subject of a split-off patent application.

    DESCRIPTION OF PERFORMANCE EXAMPLES
    Figure 1 shows a device 50 for erecting a foundation pile 20 of an offshore wind turbine from a support surface, for example a working deck 51 of a jack-up platform. The working deck 51 has a vertical side wall 51a that ends in a body of water. The foundation pile 20 has a longitudinal direction 21. In the embodiment shown, a plurality of foundation piles 20 are placed in the horizontal state on the working deck 51. Other components necessary for the installation of the foundation piles 20 and / or wind turbine tower may also be present on the working deck 51, such as a housing 52 for connection of umbilicals, and transition pieces for connection of a wind turbine tower to a placed one foundation pile 20.
    According to the detailed representation of Figure 2, the device 50 shown comprises two support beams (52a, 52b) which run substantially parallel to the support surface 51 and which
    BE2018 / 5541 support points (53a, 53b) are fixedly connected to the support surface 51. The supporting beams (52a, 52b) - and the supporting points (53a, 53b) - are designed as a truss structure to obtain sufficient strength and rigidity with the lowest possible weight. In the embodiment shown, both support beams (52a, 52b) are dimensioned such that they can both essentially only support a coupling harness 1.
    This coupling rig 1, a possible embodiment of which will be discussed in more detail below, is adapted for coupling to a wall part 20a of an end 200 of a foundation pile 20, and in the shown embodiment is fixedly connected to a free end of each support beam ( 52a, 52b) by means of connecting rods (54a, 54b) welded to the trusses which engage on ribs of the coupling harness 1. The coupling harness 1 is herein received between the supporting beams (52a, 52b). It is possible to design the connection (54a, 54b) in such a way that the coupling device 1 can rotate about a horizontal axis 55, but this is not necessary. It is also possible to design the connection (54a, 54b) in such a way that the coupling device 1 can be connected to the support beams (52a, 52b) in a longitudinal direction 21.
    As indicated in Fig. 5, the support beams (52a, 52b) are positioned at such a horizontal distance 56 apart that a foundation pile 20 to be erected can be positioned between and substantially parallel to (a longitudinal direction of) the support beams (52a, 52b) . Furthermore, the supporting beams (52a, 52b) are translatably connected to the supporting points (53a, 53b) in such a way that they can be shifted in the longitudinal direction 21 of a foundation pile 20 positioned between the supporting beams (52a, 52b) relative to the supporting points ( 53a, 53b). Because the coupling device 1 is fixedly connected to the supporting beams (52a, 52b), this coupling device 1 will also translate in use with respect to the supporting surface 51 in the longitudinal direction 21 of a foundation pile 20 positioned between the supporting beams (52a, 52b), namely of a free position in which the coupling harness 1 releases the end 200 of the foundation pile 20, to a coupling position shown in Figure 3 in which the end 200 of the foundation pile 20 is engaged by the coupling harness 1. A possible method of engagement will be further described below.
    The translation of the coupling gear 1 and / or the supporting beams (52a, 52b) relative to the working deck 51 can be done in any known manner, for example by means of
    BE2018 / 5541 hydraulic piston cylinders extending between the coupling gear 1 and / or the supporting beams (52a, 52b) and the working deck 51, and in particular by means of between the coupling gear 1 and / or the supporting beams (52a, 52b) and the supporting points ( 53a, 53b) hydraulic piston cylinders extending from the working deck 51.
    The support points (53a, 53b) can have a dual function. On the one hand they connect the support beams (52a, 52b) to the working deck 51, and on the other hand they provide a support surface for a foundation pile 20 to be erected from a horizontal position shown in the figures. This support is for instance visible in figures 3 and 4, and comprises a number of beam elements forming part of the truss that can be provided with rubber impact-collecting elements 57 to prevent damage to wall parts of the foundation pile 20. The support of the foundation pile 20 by the support points (53a, 53b) ensures, inter alia, that a foundation pile 20 arranged between the support beams (52a, 52b) does not come into contact with the working deck 51. This is, incidentally, not necessary and in other embodiments it is also possible to make contact with a foundation pile 20 and the working deck 51. It is also possible to make the support points (53a, 53b) also movable relative to the working deck 51. In such an embodiment, the device 50 can move onto the working deck 51, or other supporting surface, existing foundation piles 20, or other tubular elements. This avoids unnecessary displacement of the foundation piles 20 or other tubular elements.
    With reference to figures 7-11, a coupling harness 1 is shown for erecting a foundation pile 20 with a longitudinal direction at one end. Coupling harness 1 is also suitable for erecting and placing other elements with a longitudinal direction, such as transition pieces 'of a wind turbine mast, for example, possibly on top of each other, or on another surface. In the embodiment shown, the coupling harness 1 comprises a cross-shaped support structure in the form of mutually coupled beams (2a, 2b). However, the support structure can also comprise several beams, for example three beams which form the legs of a Y-shaped support structure. The coupling can be established, for example, by welding beam members. The beams, for example, have a tubular cross-section, but H or I beams are also possible. In the center of the cross, the support structure is provided with two hinge plates (3a, 3b) in which a lifting member 4 is provided by means of a pinhole connection
    BE2018 / 5541 is pivotally connected to the support structure 2. The lifting member 4 is provided with lifting eyes 40 on a lifting side for connection with a lifting means such as a crane (not shown), and this with the help of hoisting cables which each engage in a lifting eye 40. The function of the lifting eye 40 can also be done in a different way are designed, for example as rolling cam, axle pin or swing yoke (trunnion). The coupling rig 1 can be suspended with the lifting member 4 from a lifting means and in such a way that the support structure 2 can rotate relatively unhindered about a rotation axis 5 extending perpendicular to the hinge plates (3a, 3b).
    Coupling device 1 further comprises clamping members 6 which can be slid along the beams (2a, 2b) from a free position to a clamping position. Each clamping member 6 has a U-shaped cross-section and in this way can at least partially enclose a beam (2a, 2b) so that it clamping member 6 with sliding surfaces can slide over the relevant beam (2a, 2b) without losing contact with the beam (2a, 2b). In the embodiment shown, the clamping members 6 are slidable along an underside of the support structure 2. The underside of the support structure 2 is herein defined as the side where the lifting member 4 is not located. This lifting member 4 is located on an upper side of the cross-shaped support structure 2. The clamping members 6 can be moved over the beams (2a, 2b) by means of hydraulic piston cylinders 7 extending between a respective clamping member 6 and a beam of the supporting structure 2. to give the cylinders according to figure 8 a radially outward deviation in the indicated direction 8, the clamping members 6 are moved from a free position A radially relatively close to the center of the cross to a clamping position B further from the center of the support structure. As shown in Fig. 9, the clamping members 6 in the clamping position B abut against internal wall parts 20a of a hollow end of the foundation pile 20, wherein a clamping member portion is slid under a flange or projecting edge (not shown) of the foundation pile. This results in a mechanical coupling, optionally combined with a friction coupling between end faces of the clamping members 6 with the internal wall parts 20a of the foundation pile 2. To further improve this coupling, the end faces of the clamping members 6 which come into contact with the wall parts 20a can be provided. of shock absorbing elements such as rubber lining. The figures also show that the beams (2a, 2b) in the clamping position of the clamping members 6 are substantially transverse to a longitudinal direction 21 of the foundation pile 20.
    BE2018 / 5541. The longitudinal direction 21 in Figure 9 extends perpendicular to the plane of the figure.
    The coupling rig 1 is further provided with supporting members 9 connected to a beam (2a, 2b). The supporting members 9 are adapted to support outer wall parts 20b of the foundation pile 20, at least along parts of the circumference of the foundation pile 20. The supporting members 9 also have a U-shaped cross-section and can be slid over end parts of the beams (2a, 2b) into an adjustable fixed position of the relevant beam (2a, 2b). The adjustable fixed positions are, for example, determined by a number of openings 22 provided in a side wall of a beam (2a, 2b), into which a corresponding pin 92 of a supporting member 9 can be arranged to fix it on the beam (2a, 2b) . Because the supporting members 9 are arranged to support an outer wall part 20b of the foundation pile 20 during erecting, the supporting members 9 will generally be located more radially outward in the radial direction 8 than the clamping members 6, which in the shown embodiment are arranged around a clamping the inner wall part 20a of the foundation pile 20 when erecting.
    For foundation piles 20 with relatively large diameters, for example of 6 m and more, and / or a relatively large weight, for example 800 - 2300 tons and more, it may be useful to provide further support in the form of a support structure 25, which is distinct of the supporting members 9 and which extends at least along a part 23 of the circumference of the foundation pile 20. To obtain sufficient rigidity, it may be useful to connect the support structure 25 to at least two beams (2a, 2b), as shown in figures 2 and 3. Also the surfaces of the support structure 25 that may come into contact with wall parts of the foundation pile 20 can be provided with shock-absorbing elements 26, for example in the form of a rubber covering.
    Both the support members 9 and the support structure 25 are in use - when erecting the foundation pile 20 - on a bottom side of the foundation pile 20 in a partially erected state. The supporting members 9 and
    BE2018 / 5541 if desired, the support structure 25 are therefore especially useful in absorbing the inherent weight of the foundation pile 20.
    Finally, the coupling harness 1 can also be provided with means for adjusting the angular position of the support structure 2 relative to the lifting member 4 pivotally connected to the support structure 2. In the embodiment shown, the angle adjusting means comprise extending between the lifting member 4 and the support structure 2. hydraulic piston cylinders 24. In the retracted position of the cylinders 24 shown in Figure 10, the surface 29 of the support structure 2 extends substantially perpendicular to the surface 49 of the lifting element 4. The angle 45 between both surfaces of the lifting element 4 and the supporting structure 2 amounts to substantially 90 degrees in this lifting position. By giving the cylinders 24 a deflection, the support structure 2 is rotated around the axis of rotation 5 to a plug-in position, shown in dotted line in Figure 10, in which the surface 29 of the support structure 2 extends substantially parallel to the surface of the lifting element 4. The angle 45 between the lifting member 4 and the supporting structure 2 has hereby increased to approximately 180 degrees.
    With the embodiments of the device 50 described above, a foundation pile 20 can be erected from the working deck 51 at the end 200. First, a foundation pile 20 to be erected is positioned parallel to the working deck 51, namely between the two supporting beams (52a, 52b) running substantially parallel to the working deck 51. A relatively large part 201 of the foundation pile 20 can herein protrude over the edge 51a of the working deck 51. Subsequently, the coupling rig 1 is moved with respect to the working deck 51 under the guidance of the supporting beams (52a, 52b) in the longitudinal direction 21 of the the foundation pile 20 positioned from the support beams (52a, 52b) from a free position shown in Figures 4 and 5 in which the foundation pile 20 is not engaged to a coupling position shown in Figure 3 in which the coupling harness engages the end 200 of the foundation pile 20.
    The foundation piles 20 that are to be erected and, for example, to be placed in a seabed are generally located in horizontal position on the working deck 51. In order to receive such a horizontally oriented foundation pile 20 with the coupling gear 1, the supporting structure 2 of the coupling gear is
    BE2018 / 5541 cylinders 24 to be extended into the insertion position shown in dotted line in Figure 10 and inserted into a hollow end of the foundation pile 20. The clamping members 6 are then in the free position A, that is to say relatively close to the center of the cross. In this way, damage to wall parts of the foundation pile 20 is prevented. The clamping members 6 are then moved along the beams (2a, 2b) from their free position A to their clamping position B, whereby a frictional coupling with the internal wall parts 20a of the hollow end of the foundation pile 2 is established. In this clamping position, the beams (2a, 2b) extend substantially transversely to the longitudinal direction of the foundation pile 20.
    The coupling device 1 is then connected to a hoisting cable (not shown) of a crane (not shown) by connecting the hoisting cable to the eyes 40 or alternatively connecting means of the lifting device 4. Subsequently, the foundation pile 20 coupled to the coupling device 1 is erected by hoisting the whole with the crane. Here, the support structure 2 can optionally pivot relative to the lifting member 4 until the angle 45 is reduced to 90 degrees, in other words until the surface 29 of the supporting structure 2 extends substantially perpendicularly to the surface 49 of the lifting member 4. In this position the foundation pile 20 coupled to the coupling rig 1 is hoisted with the crane to a desired position, for instance where the foundation pile 20 has to be lowered on the seabed. In the desired position the clamping members 6 are then shifted radially inwardly along the beams (2a, 2b) from the clamping position B to the free position A in order to disconnect the coupling harness 1 from the foundation pile 20. When the foundation pile 20 is erected, it can if desired further supported by the support members 9 and / or the support structure 25.
    Another embodiment of the invention is shown in Figures 12-16. Insofar as the numbering in figures 12-16 is the same as in figures 1-6, this means the same elements. 12, a device 150 is shown for erecting a foundation pile 20 of an offshore wind turbine from a working deck 51 of a jack-up platform at an end 200. In the embodiment shown, a plurality of foundation piles 20 are placed in horizontal position on the working deck 51.
    BE2018 / 5541
    According to the detailed representation of Figure 12, the device 150 shown comprises a support beam 52 running substantially parallel to the supporting surface 51 (i.e. substantially horizontal), which beam is rotatably connected in a supporting point 53 around an axis 70 extending perpendicular to the working deck 51 to the supporting surface 51 . The support beam 52 is designed as a truss structure to obtain sufficient strength and rigidity with the lowest possible weight. In the embodiment shown, the support beam 52 is dimensioned such that it can essentially only carry a coupling harness 1.
    In this embodiment, this coupling device 1 which has already been discussed in detail above is rotatably connected around a vertical axis 71 to a free end of the support beam 52 by means of a hinge which engages a frame 72 of the coupling device 1. Furthermore, as is good can be seen in figure 15, the coupling harness 1 is translatably connected in the longitudinal direction 73 of the support beam 52 to the support beam.
    As further indicated in Fig. 15, the support beam 52 can be rotated around the hinge 74 of the support point 53 about the (vertical) axis 70 extending perpendicularly to the working deck 51, such that a foundation pile 20 to be erected is in the range of the Coupling tool 1 mounted on the support beam 52 By rotating the support beam 52 and the coupling harness 1 about their respective axes (70, 71) and also translating the coupling harness 1 along the support beam 52 with respect to the support surface 51 and in the longitudinal direction 21 from a foundation pile 20 positioned in the area of the support beam 52, the coupling device 1 can be brought from a free position, in which the coupling device 1 releases the end 200 of the foundation pile 20, to a coupling position in which the end 200 of the foundation pile 20 is coupling harness 1 is engaged. A possible method of engagement has already been described above.
    The rotation of the coupling rig 1 and / or of the support beam 52 relative to the working deck 51 can take place in any known manner. For the support beam 52 this can be done, for example, by means of a hydraulic piston cylinder 75 extending between the support beam 52 and the support point 53.
    It is optionally possible to make the support point 53 movable relative to the working deck 51. In such an embodiment, the device 150 can move to foundation piles 20 present on the working deck 51, or other supporting surface, or other tubular
    BE2018 / 5541 elements. This avoids unnecessary displacement of the foundation piles 20 or other tubular elements.
    It will be clear that the embodiments described above must be provided with peripheral equipment such as, for example, hydraulic and electrical power sources, supply lines therefor and the like. This peripheral equipment is not described in further detail.
    With the embodiment of the invented device described in detail above, a tubular object, in particular a foundation pile of a wind turbine, and / or a wind turbine tower to be placed on an already installed foundation, from a floating vessel on a subsurface, in particular a underwater bottom, and this in worse weather conditions than is possible with the known method. The risk of damage to the tubular object is hereby reduced. The device also makes it possible to manipulate tubular elements with relatively large dimensions, whereby different dimensions can be accommodated.
