    Device and method for assembling a structure at sea
    The invention relates to a device for assembling a structure at sea. The invention also relates to a method for assembling a structure at sea. The invention relates in particular to a device and method for assembling a offshore wind turbine.
    The number of structures being built, maintained and / or repaired at sea is growing. A typical example relates to an offshore wind turbine, which comprises a gondola (also referred to as a nacelle) placed on a mast, which forms the housing for electromechanical equipment, such as a power generator. The gondola is furthermore provided with a hub (also referred to as hub), on which a number of rotor blades are mounted. The rotor blades convert the kinetic energy of the wind into a rotating movement of the axis of the gondola, which is converted into electrical energy by the power generator.
    For assembling such large structures at sea, according to the state of the art, the components are manipulated from the vessel by a hoist placed on the vessel and placed on a supporting structure already present in the sea for the structure. In the case of a wind turbine, the support structure may, for example, comprise a mast placed on a suitable foundation.
    The lifting and placing of large and heavy components at sea is hampered by wind loads. Because parts such as wind turbine blades are strongly subjected to wind load, hoisted parts can be exposed to large and unforeseen movements with respect to the support structure or with respect to parts that have already been installed, which makes assembly much more difficult or even impossible.
    An object of the present invention is to provide a device with which parts of large structures can be assembled and placed at sea, in particular wind turbines, in a less wind-sensitive manner.
    This object is achieved by a device with the features according to claim 1. A device according to the invention for assembling at sea a building made up of parts, in particular a wind turbine, comprises a lifting means placed on a vessel for placing a part on a support structure present in the sea, wherein a boom of the hoisting means is provided with a piling rope with fastening means, such as a hoist, for releasably securing the part to be lifted to the boom, the boom further comprising a guide device for the fixing means, guide device is connected to the boom by means of a displacement device displaceable along a longitudinal axis of the boom, and the guide device is adapted to limit movement of the fastening means in at least one direction. Lifting a component hanging from a lifting cable is wind sensitive. By making use of the guide device, the movement of the fastening means is limited, at least during a part of the lifting and lowering, at the moment that components are coupled for assembly. As a result, undesired movements of the component are also limited and a large structure can be assembled at sea in a more efficient and safe manner.
    A further advantage of the device according to the invention is that it allows to operate in significantly unfavorable conditions, where the known device can only be used up to certain wind speeds. This can significantly reduce the assembly time of a structure at sea. The guide device can easily be moved along the longitudinal axis of the boom, for example away from the fastening means, whereby the lifting means can act as a lifting means known in the prior art. By releasing the fastening means, the accessibility of parts to be received by the lifting means from the deck of the vessel remains as good as ever.
    In an embodiment of the invention, the guide device comprises a clamping device for the fastener, whereby movement of the fastener relative to the guide device is substantially prevented. This embodiment has the advantage that the wind sensitivity of lifting is further reduced.
    Another embodiment of the device according to the invention is characterized in that the guide device comprises a frame of mutually connected beams of which at least two beams extend from the boom in the direction of the fixing means and at least partially enclose the fixing means. The at least two beams can for instance be connected to a base beam running in a transverse direction of the boom. The two beams extend on either side of the fastener and therefore limit the movement of the fastener in a direction extending transversely to the beams. This embodiment has the advantage that movements of the fastening means in other directions, for example in a lifting direction, are virtually not impeded.
    In one embodiment, the at least two beams extend substantially perpendicular to the longitudinal axis of the boom, because in this way they cover the greatest distance from the boom. Although this distance is in principle not limited, a practical embodiment is characterized in that the at least two beams extend from the boom over a perpendicular distance of at most twice the boom width. This distance is preferably no more than 1.5 times the boom width. The boom width refers to the transverse dimension of the boom running perpendicular to the longitudinal axis of the boom and perpendicular to the direction of the beams.
    An embodiment of the invention is characterized in that the clamping device is formed by at least one clamping beam which is attached to the at least one beam and which is movable to the fixing means for clamping. This embodiment provides a reliable clamping device for the fastener. An accurate operation of the clamping device is provided by an embodiment in which it comprises linear displacement means for the displacement of the clamp beam (s). Suitable linear displacement means include, for example, hydraulic cylinders connected to one end of one or more yokes rotatable about an axis, which in turn are attached to a clamping beam at another end. By giving the hydraulic cylinders a stroke, the yokes are rotated about their axis, whereby the yoke ends secured with the clamping beam are moved and the clamping beam is moved towards the fastening means.
    According to the invention, the guide device can be moved along the longitudinal axis of the boom by means of a displacement device. An embodiment of the device is characterized in that the displacement device comprises first and second cooperating guide means provided on the guide device and the boom. In an advantageous embodiment the first guide means comprise a wheel pair and the second guide means a T-beam, the wheel pair comprising a flange of the T-beam. This embodiment provides a smooth displacement along the boom, the pair of wheels ensuring that the guide device cannot move away from the boom, neither in the direction of the boom, nor in a direction away from the boom, nor in the direction transverse to the boom. .
    A particularly advantageous embodiment of the device is characterized in that the displacement device is arranged so that the guide device follows the displacement of the fastening means in case the fastening means is raised or lowered. This is preferably achieved by an embodiment in which the displacement device comprises a tension cable attached to the guiding device which is operated by a constant tensile force winch so that the tensile force in the tension cable remains essentially constant, preferably in such a way that the guiding device with a small vertical force rests on the fastener. For this purpose, the fastening means is equipped with a running wheel on each side on which the guide device rests.
    Another embodiment provides a device whose guide device comprises auxiliary devices, preferably a guide winch (tugger winch) with guide cable and / or a power source. This embodiment provides a guide device which can function autonomously and which if desired should only be connected to a lifting device known per se. With the guide cable (tugger cable) a hoisted part can be grasped and manipulated to enable an even more accurate positioning thereof. The guide cable is attracted or celebrated by means of the present tugger winch. In a practical embodiment the tugger cable is guided along a crossbar connected to the frame of the guide device by means of pulleys mounted on the crossbar.
    Another embodiment provides a device of which the fastening means is connected by means of a rigid or flexible connection to a fastening structure to which a component can be releasably fastened. This embodiment has the advantage that the attachment structure can be selected in dependence on the part to be lifted. Because of a more accurate positioning, an embodiment in which the fixing means is connected to the fixing structure by means of a rigid connection is preferred.
    It here has further advantages to characterize an embodiment of the device in that the rigid connection and / or the mounting structure comprises means for moving and / or rotating the mounting structure and / or parts of the mounting structure in 3 dimensions respectively. This embodiment has the advantage that the part, after it has been brought by the lifting means in the vicinity of the desired installation position, can be accurately moved and rotated about an axis of rotation in order to accurately guide the part to the installation position. In the case of a wind turbine blade, for example, this feature gives the possibility of attaching the blade to a hub, even when the blade attachment of the hub makes an angle different from zero with the horizontal. Due to precise movements of the fastening structure, a blade can be mounted without additional movements of the lifting device.
    In an embodiment of the device according to the invention, the fixing structure comprises a yoke. For example, when lifting a wind turbine blade, the yoke gives the desired width to the fastening means, so that the wind turbine blade does not tilt. A preferred embodiment herein has the feature that the fastening structure comprises a leaf yoke.
    A particularly advantageous embodiment of the invention provides a device whose mounting structure comprises an orientable rotor blade spreader. The rotor blade spreader is an elongated structure with a longitudinal direction, a transverse direction, and a vertical direction that in the present embodiment corresponds to the lifting direction. The spreader is provided with means to rotate the spreader around a longitudinal axis and a transverse axis, and to pivot about a vertical axis, for example by means of a motor-driven pinion. In addition, the length in the longitudinal direction of the spreader is preferably telescopically adjustable. For example, it can be adjusted to the length of the engagement portion of an elongated component, such as a wind turbine blade. It is also advantageous if the spreader is provided with a mechanism for moving the rotor blade in the longitudinal direction. The center of gravity can hereby be made adjustable and the mounting bolts of a rotor blade can be pushed during assembly via a translation into the corresponding holes in the hub without additional lifting means displacement. The spreader is further provided with engaging means in the form of, for example, gripping arms, carrying straps, clamping mechanisms and the like in order to be able to hold the part.
    An embodiment of the device according to the invention is characterized in that the mounting structure comprises a gripper. In another embodiment, the fastening structure comprises carrying straps for including a component, in particular a wind turbine blade. The carrying straps are wrapped around a cross-section of the blade and prevent paint layer and other damage to the blade.
    The device according to the invention is particularly suitable for manipulating parts comprising a mast, a rotor blade and / or a gondola of a wind turbine. The invented device makes it possible to mount offshore wind turbines up to wind speeds of 12 m / s and, where with the known device the mast and gondola can be mounted up to wind speeds of 10 m / s, a full rotor (a hub on which 3 blades are mounted) ) up to 9 m / s, a gondola with hub and 2 pre-assembled blades (the so-called bunny ear method) up to about 9 m / s and individual rotor blades up to 8 m / s. The vessel preferably comprises a jack-up platform.
    The invention also relates to a method for assembling a large structure at sea, in particular a wind turbine, using the device according to the invention. The method comprises providing a device according to the invention on a vessel, and placing the components on a support structure present in the sea with the aid of the lifting means, wherein the movement of the fastening means is temporarily limited in at least one direction by the guiding device by means of moving the displacement device along the longitudinal axis of the boom to the height of the fastener. By making use of the device according to the invention, a component, in particular a wind turbine blade, can be attached to a support structure at sea under windy conditions. Conversely, the device provides possibilities for a new method for dismantling a structure at sea, in particular the components of a wind turbine.
    An embodiment of the invented method is characterized in that the movement of the fastening means relative to the guide device is substantially prevented by clamping the fastening means in the clamping device.
    Another embodiment comprises a method in which the guide device is passively moved along the longitudinal axis of the boom by means of a pulling cable attached thereto with a substantially constant pulling force by lifting or lowering the fastening means. The guide device rests with a low weight on wheels on each side of the fastener.
    A particularly suitable embodiment comprises the steps of: a) receiving a component with the fastening means or the fastening structure; b) tilting the boom up until it runs so steep that the fastener comes within the reach of the guide device; c) moving the guide device along the longitudinal axis of the boom until it rests on the wheels of the fastener, the hoisting winch of the guide device being subsequently switched to constant pulling force operation; d) pivoting the boom into the vicinity of the desired assembly position; e) clamping the fastener with the guide device; f) tilting the boom until the part is in the desired assembly position; g) fully or partially detaching the fastener; and h) lowering the part into the desired assembly position.
    When the clamping device is active, displacements of the boom for correcting the range as well as the lowering of the hoist for placing the mast or gondola are preferably limited to approximately 500 mm. With larger displacements, undesirably large, approximately horizontal forces can arise on the guide device, because the hoisting wires of the hoist are pulled out of the vertical position.
    If larger displacements were nevertheless desired, the clamping force of the guiding device can be reduced such that the clamping is indeed large enough to absorb gusts of wind, but smaller than the forces that arise from horizontal or vertical movements of more than 500 mm. This can be achieved through a partial detachment.
    In yet another embodiment of the method according to the invention, lowering the component in step h) to the desired assembly position comprises moving and / or rotating the mounting structure and / or parts of the mounting structure in 3 dimensions. This allows the component to be positioned more accurately.
    The invention will now be explained in more detail with reference to the accompanying figures, without being otherwise limited thereto. In the figures: FIG. 1A-1B schematic side views of an embodiment of the device according to the invention in various states;

    Figure 1 shows a side view of various states of a device 1 according to the invention. The embodiment shown is adapted for assembling a wind turbine at sea on a support structure in the form of a jacket 3. It will be clear that the invention is not limited to a support structure in the form of a jacket, and any other foundation can are applied. With a rather low water depth, for example, healed piles (monopiles) with a so-called "Hransition piece" - a round transition structure from monopile to the mast attachment located near the waterline - can be used. With low water depth, "gravity based foundations" can also be applied. For larger water depths or larger wind turbines, so-called Tripods and Tripiles are used in addition to jackets. The wind turbine components to be placed include the wind turbine mast 2, the gondola 21, which is shown in different positions in figures 1A-1B, and / or the rotor blades 22 of the wind turbine. The device 1 comprises a lifting means 5 placed on a vessel 4, preferably a hoisting crane, a boom 6 of which is provided with a piling cable 7 to which a fastening means, such as a hoist bar 8, is arranged, and to which a component for lifting can be releasably attached . The boom 6 is pivotally connected about a fixed end 6a to a platform 50a lifting means, which in turn is rotatable about a rotation axis 51 about a platform foundation 50b. The boom 6 can be raised in a known manner around the pivot point 6a, i.e. lifted, and tipped, i.e. lowered. In figures 1A-1B the hoist hoist 8 is also shown in different positions and the part to be lifted relates to a gondola 21. The vessel 4 comprises a jack-up offshore platform which is provided with anchoring posts 40 which support a working deck 41. The anchoring piles 40 are movable in vertical direction up to the seabed and the height position of the working deck 41 relative to the water level can be changed by shifting the working deck 41 relative to the posts 40 by means of (hydraulic) jacks or a rack and pinion pinion drive system. The working deck 41 is provided, if desired, with storage locations for the parts to be lifted and positioned. In order to be able to carry out the method according to the invention, the vessel 4 is moored in the immediate vicinity of the support structure 3 present in the sea, and in any case such that the support structure 3 is in the range of the lifting means 5 with the boom 6 in top condition.
    According to the invention, the boom 6 comprises a guide device 10 for the hoist hoist 8, with which the movement of the hoist hoist 8 in at least one direction 61 can be limited. This restriction direction 61 will generally be a direction extending transversely to the longitudinal axis 60 of the boom 6, but this is not necessary. According to Figure 2a, the hoist bar 8 generally comprises a disc housing 80 and a hoisting hook 81. The hoist bar 8 is provided on both sides with wheels 80a and 80b on which guide device 10 can rest with little force. Because the guide device 10 rests on the wheels (80a, 80b) of the hoist link 8 with a relatively low weight, the guide device 10 will follow the hoist link 8 in a substantially passive manner. The relatively low weight takes care of a hoisting winch of guide device 10 (not shown), wherein this operating mode is preferably set via a so-called constant pulling force operating mode. The greater part of the weight is absorbed by the tensile force in the hoisting wire of the guide device 10. The wheels (80a, 80b) of the hoist hoist 8 ensure that this hoist hoist 8 experiences virtually no resistance forces in the longitudinal direction (the direction of beams 101a, 101b) and therefore remains suspended vertically under the hoisting discs at the top of the boom 6.
    An embodiment of a guide device 10 is shown in more detail in Figures 2A, 2B and 2C. The shown guiding device 10 comprises a frame of interconnected beams, at least two of which (101a, 101b) extend from a rectangular base frame formed by 2 cross beams (103a, 103b) and two vertical beams (104a, 104b) from the boom 6 into extend in the direction of the hoist hoist 8, and this substantially perpendicular to the longitudinal axis 60 of the boom 6. The frame is further reinforced by two slant beams (102a, 102b) and two slant beams (102a ', 102b'). The length of the beams (101a, 101b) is such that they at least partially enclose the hoist bar 8, and in particular the disc housing 80 thereof. The position of the hoist hoist 8 between the beams (101a, 101b) depends on the extent to which the boom is tucked up and the height of hoist hoist 8. Because hoist hoist 8 is suspended from the pile rope 7, the left position A shown in Figure 2A will of the disk housing 80 can usually be achieved by lifting the boom 6 such that the reach of hoist bar corresponds to the center line of foundation 3 of the turbine mast and the hoisting height of hoist bar 8 corresponds to the highest required hoisting height of a wind turbine component. The right-hand position B will generally be achieved with the same boom position, but with a lower required lifting height of wind turbine components, ie in the case of wind turbines with a shorter mast. The two beams (101a, 101b) preferably extend over a perpendicular distance 62 from the boom 6 of at most two times the boom width 63 to provide sufficient rigidity. The guiding device 10 is furthermore provided with a clamping device for the hoisting hoist 8 in the form of a clamping bar 105 which is fixed with yokes 106 to a bar (101a or 101b) and which is movable to the hoisting hoist 8 for clamping. The displacement of the clamping beam 105 can be effected, for example, by the linear displacement means in the form of a hydraulic cylinder 107 mounted on the base frame and which controls one of the yokes 106. By pressing the clamping bar 105 with the hydraulic cylinder 107 clampingly against the hoist bar 8, more particularly against the disk housing 80, movement of the hoist bar 80 relative to the guide device 10 is substantially prevented. The hoist 8 is thus immobilized relative to the guide device 10, and thus also relative to the boom 6. As a result, a component connected to the hoist bar 8 can be positioned with greater accuracy, even in strong winds. The advantage is that a per se known lifting means 5 in the form of a crane with boom 6 can be deployed, and that the immobilisation of the engagement with a component can be canceled at any moment.
    The guide device 10 is movably connected to the boom 6 along the longitudinal axis 60 by means of a displacement device (108, 109, traction rope, hoisting disc and winch). The guide device 10 and the boom 6 are provided for this purpose with first and second cooperating guide means (108, 109), which together with a pulling cable, hoisting disc and winch (not shown) attached to the guide device 10 form the displacement device. The first guide means comprise wheel sets 108 mounted on the base frame (103, 104), and the second guide means with T-beams 109 connected to the side of the boom 6 facing the conduit device 10. Each pair of wheels 108 comprises the flange of a corresponding T-beam 109, wherein wheels of a wheel set 108 are located on both sides of the flange and roll over them. In particular, each wheel set is provided with a wheel running on the flange 109 'of the T-profile 109 provided on the boom sleeve for absorbing compressive forces, and two running wheels which on the other side are against the flange 109' of the T-beam. profile 109 for taking up tensile forces. If desired, transverse rollers are provided on one side of the boom which run on the end face of the flange 109 'of the T-profile 109 to hold the guide device 10 on the rails in transverse direction. Depending on the wheel load, wheels can possibly be replaced by boggies with a double wheel. It is of course possible to achieve other modes of mobility along the boom 6.
    The tension cable (not shown) attached to the guide device 10 is preferably operated by a constant tension force winch (not shown) so that the tension in the tension cable remains substantially constant, and is kept at a generally relatively low value in the situation that the guidance device is active and rests with little force on the wheels of hoist 8. The constant tensile force winch is located, for example, on the boom 6, for example on a transverse sleeve in the vicinity of the hinge construction in the vicinity of hinge 6a, approximately in the middle of the boom. The hoisting disc for the guide device is preferably located at the upper end of the boom 6.
    The guiding device 10 can, if desired, be provided with auxiliary devices. As shown in Figure 2C, such an auxiliary device may comprise a tugger winch 110, and possibly power sources (not shown). A guide cable 111 (tugger cable) extends from the tugger winch 110 and can be connected to a component connected to the hoist link 8. By lengthening or shortening the guide cable 111 with the winch 110, the component can be accurately positioned. The guide cable 111 can be easily connected to the base frame (103, 104) through a hanging frame (201, 202), which is connected to the base frame (103, 104) and is made up of vertical beams 201 and a crossbar 202 which is also provided with wheel sets 108 cooperating with the T-beam 109. The transverse beam 202 has sufficient length to suspend pulleys 203 at the ends such that the guide cables can engage approximately perpendicular to the part to be hoisted. This makes guiding the tugger system the most efficient.
    As shown in Figure 6, a gondola 21 of a wind turbine can be received by a cross yoke 202, which is connected by means of hanging cables 211 to hoisting eyes 210 mounted on the gondola 21. The cross yoke 202 is connected to the hoisting hook 81 by means of hanging cables 212. By clamping the hoist bar 80 with the guide device 10, a substantially rigid connection is obtained between the hoist bar 8 and the boom 6. This prevents the movements of the gondola 21 under the influence of wind and boom movements. The guide cables 111 connected to gondola 21 make it possible to precisely control the rotation of gondola 21.
    Figures 3A and 3B show an embodiment in which the hoisting pulley 8 is connected by a flexible connection to a fastening structure in the form of a hoisting yoke 300 extending in the transverse direction 61 to which a wind turbine or rotor blade 22 is releasably attached. The flexible connection is formed by two suspension cables 301 which extend from the lifting eye 81 to attachment points 302 arranged on the lifting yoke 300. The blade 22 is more or less in the horizontal position.
    The rotor blade 22 is suspended in supporting belts 303 attached to the lifting yoke 300.
    Figures 4A, 4B and 4C show an embodiment in which the hoisting pulley 8 is connected by means of a rigid connection to a fastening structure, also in the form of a hoisting yoke or rotor blade spreader 406 extending in the transverse direction 61, to which a wind turbine or rotor blade 22 can be releasable be confirmed, see Figures 5A and 5B. The rigid connection comprises a T-shaped bridging structure 400 which is connected with transverse connections (401a, 401b) to the disk housing 80. The bridging structure 400 bridges the lifting hook 81. The rotor blade spreader construction 406 is rotatably connected to the hinge 400a, which in this case embodiment forms an actuator 402 with which spreader 406 can be connected or forms part thereof. The actuator 402 is rotatable around the axis 400a in a transverse direction 61 by means of hydraulic cylinders (403a, 403b). The actuator 402 and spreader 406 further comprise means for moving and / or rotating parts of the fastening structure in 3 dimensions. For example, a rotation axis 400b rotatable about a rotation axis 400b extending perpendicular to the axis 400a can be rotated by the action of hydraulic cylinder 404a and / or 404b. This will also rotate the telescopically extendable arms (406a, 406b) of the rotor blade spreader 406. By extending the arms (406a, 406b), the length of the spreader 406 is increased if desired and adapted to the part to be lifted.
    A rotor blade 22 can be suspended in two carrying straps 303 attached to the spreader, as has already been described above in an embodiment with a lifting yoke 400 or 406. The combination of displacement and rotation actuators gives the possibility of precisely locating a wind turbine blade in a random orientation positions with respect to the boom 6, and thus also with respect to the support structure 3 and therefore also with a gondola 21 mounted on the mast 2.
    It will be clear that for operating the various components of the guiding device 10, such as for example the tugger winches and the hydraulic cylinders, power provisions such as batteries, motors, pumps and the like (not shown) are present. It is also possible to place these provisions wholly or partially on the crane structure 5, wherein the hydraulic hoses, electrical and mechanical cables, and the like, required for energizing the parts are carried along the boom to the guide device 10. However, the power provisions are preferably provided on the guide device 10 itself and the required energy is fed to the guide device 10 via a so-called umbilical hoisting cable. An umbilical hoisting cable comprises a steel cable whose core does not contain a strand but, for example, an electrical supply cable. In this way, energy can simply be supplied to the guide device 10 via slip rings in the hoisting winch drum. The power supply for the various actuators on the rotor blade spreader is most easily carried out by electric or hydraulic accumulators on the spreader itself. The various functions are most easily operated with a radio remote control.
    Figures 1A - 1B illustrate the placement of a gondola 21 on a wind turbine mast 2 with a method according to the invention. The method comprises providing a device 1 according to the invention on a vessel 4 and placing a component from the vessel 4 onto a support structure 3 present in the sea with the aid of the lifting means 5, wherein the movement of the hoist link 8 temporarily at least one direction is limited by moving the guide device 10 by means of the displacement device (108, 109, traction rope), from the highest position in the boom, along the longitudinal axis 60 of the boom 6 to the height of the hoist 8. After contact of the guide device 10 with the wheels 80a of hoist 8, the hoisting winch of guide device 10 is put into constant tension operation. When hoisting and celebrating hoist hoist 8, guide device 10 therefore continues to passively follow hoist hoist 8 because the guide device rests on the wheels (80a, 80b) of hoist hoist 8 with a small weight. In this situation, the transverse movement of hoist 8, direction 61, is prevented by the beams 101a, 101b. When the boom 6 is at the correct angle to reach the center line of the support structure 3, the movement of the hoist bar 8 relative to the guide device 10 is preferably substantially prevented by clamping the hoist bar 8 in the clamping device (105 , 106, 107) of the guide device 10.
    The gondola 21 is connected to a hoist hoist 8 with a conventional hoisting yoke and hoisting cables (slings). The method according to the embodiment shown comprises, inter alia, the steps of receiving the hoist hoist 8 from the working deck 41 of the vessel 4 up to and including the hoist hoist. a first position A, wherein the guide device 10 is held in a high position of the boom 6 so that the hoist bar 8 can move freely and the boom 6 behaves like a boom 6 of a known crane. This allows the hoist bar 8 to move easily on and along the working deck 41, for example in storage racks for the parts, without this movement being impeded by guide and clamping devices attached to the boom 6. The boom 6 is then tilted upwards about the axis of rotation 6a (tucked up) until it runs so steep that the hoisting cable 7 of the hoist 8 comes within the range of the guide device 10 (in a direction transverse to the boom 6). The guide device 10 is then moved along the longitudinal axis 60 of the boom 6 to approximately at the height of the hoist link 8, the guide device 10 resting on the wheels (80a, 80b) of the hoist link 8, whereafter the hoisting winch of the hoist (not shown) the guide device 10 is put into constant pulling force operation so that the guide device 10 passively follows the movements of the boom 6 and the hoist 8. The gondola 21 is then hoisted from a position A to a position B, the guide device 10 following the movement of the hoist bar 8 passively. The boom 6 is then pivoted about the axis of rotation 51 to the vicinity of the desired assembly position (see Figure 1B). The hoist 8 is clamped with the guide device 10 in the manner described above in detail, and the boom 6 is tilted until the gondola 21 is in the desired assembly position. The lifting hoist 8 is released from the guide device by unlocking the clamping device (105, 106, 107) and the gondola 21 is lowered to or against the already present support structure 3 or other already placed parts. This last step preferably comprises moving and / or rotating in 3 dimensions one of the fastening structures and / or parts of fastening structures described above in detail.
    The operations described above are repeated as often as parts are to be fitted.
    The invention is not limited to the embodiments shown in the figures, and many variants thereof are possible within the scope of the appended claims. For example, it is possible to place the rotor blades 22 separately, or, on the contrary, to attach one or more rotor blades 22 to the hub or gondola 21 (for example in so-called bunny form) and to place the whole on the support structure 3 with the aid of the described device and method.
