    BACKGROUND OF THE INVENTION 1. Field of the invention
    [001] The present invention relates to techniques for handling energy systems, such as windmills, wind turbines and / or other devices, used to convert wind into energy. Such handling may involve installing, storing and / or transferring the windmills. 2. Fundamentals of Related Technique
    [002] Conventional windmills (sometimes referred to as wind turbines) typically imply a conical turbine tower and a wind turbine nacelle positioned above the tower. A wind turbine rotor with multiple wind turbine blades is connected to the nacelle via a shaft mechanism, which extends out of the nacelle.
    [003] Wind turbine towers (consisting of tower units) can be hundreds of feet high, requiring heavy equipment to supply at a site and / or construction on the job site, and presenting a high risk of injury to workers. Conveyors, such as boats, have been used to transport wind systems to locations, such as offshore resources, for installation. Offshore windmill installation has been carried out with large capacity cranes. In some cases, cranes are used in combination with the conveyor to transfer the windmill from the conveyor and / or install the windmill. These conveyors and large cranes can present a high safety risk when operated in high winds, which limits the supply and / or installation window to approximately a few months a year.
    [004] Examples of techniques for supplying and / or installing a windmill are described in U.S. Patents 4,311,434, 7,456,515, 7,112,010 and 7,234,409. Despite the existence of such techniques, there remains a need for improved techniques for transport, transfer, storage, assembly and / or installation of wind turbines. SUMMARY OF THE INVENTION
    [005] In at least one aspect, the present invention relates to a conveyor system for providing at least one component of a windmill in one location. The system is provided with a conveyor and a transport system. The conveyor is positioned adjacent to a base on site. The transport system is provided with a plurality of tracks, a support and at least one slide. The rails are positioned on the base and on the conveyor. The holder has a first portion of the charger rails on it. The support is positionable along a second portion of the rails on a surface of the conveyor, and slidably movable between a retracted and an extended position whereby the support is selectively positioned adjacent to the base. The slider carries the component (s), and is slidably movable along the conveyor and base rails whereby the component (s) is / are slidably transferable between the conveyor and the base.
    [006] In another aspect, the present invention relates to a transport system for supplying at least one component of a windmill in one location. The system is provided with a conveyor to transport the windmill component (s) to a base on site, and a transport system with at least one slide to load the windmill component (s) wind. The carrier has a plurality of legs of the carrier extendable therefrom to selectively lift the carrier to a desired height. The slide is movable between the conveyor and the base.
    [007] Finally, in another aspect, the present invention relates to a method of transferring at least one component of a windmill in one location. The method involves providing a transportation system. The system is provided with a conveyor for transporting at least one component of the windmill to a base on site, and a transport system comprising at least one slide for loading the component (s) of the windmill. The carrier has a plurality of legs of the carrier extendable therefrom to selectively lift the carrier to a desired height. The slide is movable between the conveyor and the base. The method additionally involves transporting the windmill component (s) to the site via the charger, and transferring the windmill component (s) between the conveyor and the base via the transport system.

    [0049] Currently preferred embodiments of the invention are shown in the above-identified figures and described in detail below.
    [0050] Aspects of the invention imply a mobile turbine loader and cargo handling system 100 (sometimes referred to as the "cargo handling system"). Figures 1-24 represent several schematic views of the cargo handling system 100. Figure 1 shows a version of system 100 configured for offshore applications. Although the cargo handling system 100 can be configured for offshore applications, it is realized that the cargo handling system 100 can also be used for applications on the continent.
    [0051] As seen in figure 1, a base 10 of the cargo handling system 100 is shown suspended above sea level 12. Base 10 is shown configured with three pillars or extendable platform legs 14. A lower track structure 16 is attached to platform legs 14 and suspended below sea level 12. Base 10 and / or mat structure 16 is / are configured to keep the base afloat while platform legs 14 are suspended on the ocean floor. Some aspects can be implemented with more or less than three platform legs 14, depending on the layout and configuration of the base 10 and mat structure 16. The mat structure 16 is preferably suspended via the legs 14 a distance below the base 10. Preferably , the lower track structure 16 provides stability and support to the cargo handling system 100 during operation.
    [0052] The cargo handling system 100 of figure 1 is shown equipped with an optional crane 17, heliport 18 and pile driver 19. Other devices can also be provided around the cargo handling system 100 to perform various operations, such as steering, driving or otherwise facilitating the transportation of the cargo handling system 100. In another example, manipulators can be provided for storing and installing components in the cargo handling system and / or facilitating the transfer of components in the cargo handling system, as will be described further below. Aspects of the base 10, platform legs 14 and track structure 16, as well as other components of the invention, can be implemented using conventional oilfield jackup load handling components and machinery, known in the art.
    [0053] The base 10 is equipped with several charger supports 20, each configured to embed one or more nacelles of conventional wind turbines 22. This particular aspect of the invention is shown with each nacelle 22 equipped with a pair of blades 32. One wind turbine rotor 23 is operationally connected to each nacelle to support one or more blades 32 in it. As shown, multiple nacelles 22, each with two paddles 32 in it, are stacked on supports 20 positioned about the base 10. The supports 20 can be, for example, frames stacked using locking ends to hold the supports 20 in place on the base. 10. One or more nacelles 22 with zero or more blades 32 can be positioned and / or stacked on top of the cargo handling system. Nacelles 22 can be stored with some of the paddles 32 pre-installed, as shown, or removed for separate storage and / or installation.
    [0054] A handling system comprising a lifting platform 24 is positioned between two of the platform legs 14. The lifting platform 24 has two holes 25 through it to receive the platform legs 14. The lifting platform 24 is operationally connected on the two legs of platform 14 and slidingly movable along it. The lifting platform 24 is configured to run up and down along the legs of the platform 14, as described in detail below.
    [0055] The lifting platform 24 is additionally configured with a handling set or loader 26 configured for movement along the lifting platform 24, and with respect to it, via a trolley 27. Some aspects of the invention are equipped with a plunger 28 (described below). The loader 26 is configured to receive windmill components, such as nacelles 22, blades 32 and / or tower units 30, for transportation about the cargo handling system 100. The loader 26 is also configured to position the components of the windmill for installation, storage, etc.
    [0056] A plurality of tower units (sometimes referred to as towers or poles) 30 are mounted below the lifting platform 24. The tower units are supported on base 10 by a manipulator 37a. Each tower unit 30 has a single paddle 32 held in place by a support or paddle pad 34a of the manipulator 37a. Some aspects can be implemented with each tower unit 30 equipped with one or more blade stands 34a. Other aspects can also be implemented with paddles 34a configured to contain one or more paddles 32.
    [0057] Experienced in the art, they realize that one or more nacelles, shovels, tower units and / or other components or devices can be positioned in various places about the cargo handling system 100. The platform legs 14 and / or platform lifting 24 can also be positioned in various locations. For example, one or more lifting platforms 24 can be positioned between one or more pairs of platform legs 14 located about the cargo handling system 100.
    [0058] Figure 1 shows the cargo handling system 100 being moved to a location for installing a windmill (or wind turbine tower assembly). The cargo handling system 100 can be towed, driven or otherwise transported to a desired location. The cargo handling system 100 is configured to transport one or more windmills to one or more desired locations for installation. One or more cargo handling systems can be transported separately, or in combination.
    [0059] As shown in figure 1, a base tower unit 31 can be provided on site to receive and support the windmill. The base tower unit 31 is shown extending above sea level 12. It is understood that the base tower unit 31 can be installed on the job site using conventional devices known in the art. For example, the base tower unit 31 can be transported to the site via the cargo handling system 100, and installed using a pile driver 19. The base tower unit 31 is provided to receive and support the mill. wind, as will be described further below.
    [0060] The cargo handling system 100 is represented in figure 1 carrying multiple windmills disassembled into different components or portions. The components of the windmill comprise nacelles of wind turbines 22, tower units 30 and blades 32. One or more components of one or more windmills, as well as other devices, can be transported, assembled, used and / or installed by the cargo handling system 100. One or more of the components can be transported in a disassembled, partially assembled, or completely assembled configuration, as needed. Personnel can also be transported with the cargo handling system 100.
    [0061] Figure 2 shows the cargo handling system 100 in position on the base tower unit 31. Once in position, the platform legs 14 are extended to raise or lift the base 10 to the desired height and give stability. As the platform legs 14 are extended, the belt structure 16 is lowered to the ocean floor to provide a stable support for the cargo handling system 100. The platform legs 14 can be extended in such a way that the base 10 be raised to a desired height for installation.
    [0062] The base 10 is preferably provided with an input portion 33 to receive the base tower unit 31. The load handling system 100 is positioned in such a way that the loader 26 of the handling system is adjacent to the unit of the base tower 31. In this position, personnel can access the base tower unit 31 according to the need in preparation for the installation operation.
    [0063] With the cargo handling system 100 in place on the base tower unit 31, the lifting platform 24 can be raised or lowered to carry out handling operations. The loader 26 positioned on the lifting platform 24 can be moved laterally back and forth along the lifting platform and perpendicular to it. The lifting platform 24 and the loader 26 can be positioned to pick up components, such as a nacelle 22, tower unit 30 and shovel 32.
    [0064] As shown in figure 3, aspects of the invention can be equipped with a pair of winches 35 mounted on the ends of the lifting platform 24. Activation of the winch (s) 35 raises and lowers the lifting platform 24. Conventional winch / pulley systems can be used in embodiments of the invention. Other aspects can be implemented with the winch (s) mounted above the leg (s) of platform 14. Although winches are shown in figure 3, it is clear that other mechanisms can be used to facilitate the movement of the lifting platform 24 along platform legs 14. Winches, cranes or other mechanisms can also be provided about other positions of the cargo handling system 100 to perform various operations, such as installation.
    [0065] Figure 4 shows the loader 26 moved to the position to catch a desired nacelle 22. The loader 26 is lifted by the lifting platform 24 to a height such that the loader 26 is in vertical alignment with the support it holds the nacelle 22. The loader 26 is then slid along the lifting platform 24 to a position in horizontal alignment with the support 20 that holds the nacelle 22. The loader 26 can be extended to a position adjacent to the support 20. In this position, the magazine is aligned to receive nacelle 22.
    [0066] Once in position, nacelle 22 is moved over loader 26, and supported by it. The nacelle 22 can be moved over the loader 26 using any suitable device (for example, via a winch mounted on the loader 26, not shown). As shown, nacelle 22 is slidably moved from support 20 to loader 26 along tracks 39. Preferably, tracks 39 are configured to align with supports 20 to facilitate transfer between them. A slide 41 is provided for sliding nacelle 22 along rails 39. In some aspects of the invention, the loader 26 and / or the loader brackets 20 can be configured with conventional gear / track systems to allow movement or extension of components to facilitate handling of the nacelle 22. Devices, such as bearings, slides, rails or other mechanisms, can be provided in the carrier and / or support to facilitate the transfer of the nacelle between them.
    [0067] Figures 5A, B, C show detailed views of the lifting platform 24 with loader 26 on it. These figures represent the movement of the lifting platform 24 and loader 26 in the X, Y and Z directions. The lifting platform 24 has holes 25 close to each end of it to receive platform legs 14 (figures 1-4) for sliding movement along it in the Y direction, as shown. Winches 35 are provided to facilitate such movement.
    [0068] The loader 26 is slidably connected to the lifting platform 24 via the trolley 27. The lifting platform 24 is an elongated element with rails 43 receptable by the trolley 27 for sliding movement along it in the X direction along the platform lifting height 24 as shown. As shown in figures 5A and 5B, the loader 26 has internal tracks 45 slidably receptable by the trolley 27 to allow movement of the loader 26 along the trolley 27 in the Z direction perpendicular to the lifting platform 24, as shown. Upper rails 39 can be used to slide nacelle 22 onto slider 41 (figure 4).
    [0069] Figure 5C shows trolley 27 in more detail. The trolley 27 is shown with external rails 47a for receiving the loader 26, and internal rails 47b for receiving the lifting platform 24. The trolley 27 is also provided with a piston that is movable in the Y direction and rotatable about a T axis. The plunger 28 allows the elevation and rotation of a windmill component, such as a nacelle (not shown), when placed in it, as will be described further below.
    [0070] Figures 6 and 7 show a close-up view of the loader 26 positioned to pick up the tower unit 30. The loader 26 is positioned about the lifting platform 24 for sliding movement along it. Figure 6 also shows the various handrails / stairs / walkways and / or other access routes 38 that can be arranged on the base 10, loader supports 20 and loader 26, in the desired manner, to provide and facilitate safe access and movement for workers .
    [0071] The loader 26 is provided with a handling arm 42 extending from the underside of the loader 26. The handling arm 42 is pivoted to the loader 26 and selectively extendable via the piston 49. As shown in figure 6, the loader 26 is positioned adjacent to a tower unit 30 with the handling arm 42 in a collapsed position to receive the tower unit 30.
    [0072] Each tower unit 30 is equipped with a strap 40 to facilitate the handling of the tower units. Figure 7 shows the handling arm 42 positioned under the loader 26 to couple the tower unit 30 with the strap 40. The strap 40 extends over the tower unit to tightly fit the tower unit for transportation. The handling arm 42 can be attached to the strap 40 using screws or other mechanisms.
    [0073] The strap 40 is coupled to a paddle 34a. The paddle rest 34a is positioned under the tower unit 30 as it is in the stored position. The paddle 34a provides support for the tower unit 30 and provides storage for a paddle 32 below it. The paddle 34a acts as a support for holding the tower unit 30 and paddle 32 secured in a stored position during transport and installation. The paddle rest is configured to rest on a surface, such as the base 10, as shown. The paddle rest 34a is also shaped to fit the shape of the tower unit 30 and resist movement of the tower unit 30 from its stored position.
    [0074] Tower units 30 are shown in a position stored in base 10. Tower units 30 and paddles 32 are preferably stored in a stable position and for easy access during installation. As shown, tower units 30 are positioned below the loader 26 for retrieval, but can be positioned at various locations around the base. In this version, a nacelle 22 was mounted on top of the loader 26 with the tower unit 30 connected below.
    [0075] Figures 8A, B show the manipulator 37a for storing a tower unit 30. The manipulator 37a comprises a strap 40 for tightly fitting a tower unit 30, and a paddle 34a for receiving a paddle 32. The strap 40 comprises a pair of clamping loops 53 operatively connected to a bar of the strap or support assembly 55. Each clamp 53 is positionable about a tower unit 30 to firmly seat and support the tower unit 30 of the assembly bar of strap 55. The clamping loops 53 are hinged in such a way that they can open to receive the tower unit 30, and lock around it (via screws or other devices not shown). Figure 8A shows the clamping loops 53 in the closed position. Figure 8B shows the clamping loops 53 in the open position.
    [0076] The strap 40 is operatively connected to the paddle rest 34a and selectively extendable from it via a telescopic member 50 of the paddle rest 34a. The telescopic member 50 may include hinges, such as piston 54, to facilitate movement of the strap from a collapsed or wrapped position shown in figure 8A, to an extended position shown in figure 8B. The telescopic element 50 can be screwed or otherwise connected to the strap 40 and paddle 34a. The telescopic element 50 is preferably selectively extensible to allow extension of the paddle 34a of the strap 40, as will be described in more detail below.
    [0077] The paddle rest 34a is provided with a seat bar 59 with a pair of feet 61 at each end thereof. The feet 61 have tower supports 63 on them. The tower supports 63 are shaped to receive the tower unit 30 and prevent its lateral movement when in the stored position. As shown, tower supports 63 are a pair of arms with an arcuate end for receiving tower unit 30, but may be of other shapes and configurations sufficient to receive and support tower unit 30.
    [0078] The feet 61 of the paddle rest 34a are preferably hinged to open to receive a paddle (for example, 32 in figure 7). The feet 61 are movable between a closed position, shown in figure 8A, and an open position, shown in figure 8B. As shown in these figures, the feet 61 can be provided with inserts 46 to fit snugly and protect the paddle. The inserts can be made of rubber or other material to support and / or protect the blade. The feet 61 also work to support the tower unit 30 and / or paddle 32 on the base 10, as shown in figure 7.
    [0079] Referring now to figure 9, with the nacelle 22 mounted on top of the loader 26 and the tower unit 30 connected below, the wind turbine and the tower unit are raised together. Windmill components, such as nacelle 22, tower unit 30 and / or shovel 32, can be moved about base 10 separately or together. The lifting platform 24 is shown carrying the nacelle 22 and the tower unit 30 to a raised position for installation.
    [0080] Figure 10A shows the tower unit 30 and blade 32 in transition to a standing position. The loader 26 has been moved along the lifting platform 24 to a position on the base tower unit 31. Once in the desired position, the handling arm 42 can be activated to position the tower unit 30 for installation. As seen in figure 10A, the paddle 34a is preferably equipped with inserts 46 to hold the paddle 32 in place without damaging it.
    [0081] Figure 10B is a side view, showing the handling arm 42 extending outwardly to pivot the tower unit 30 to a standing position. Aspects of the invention can be implemented with any suitable handling arm 42 or extension mechanism, known in the art (for example, pneumatic, hydraulic, electric servo, etc.) Piston 49 is provided to extend the arm from the collapsed position to a position extended as shown.
    [0082] Once the tower unit 30 is vertical and in place the tower unit 30 is attached to the base tower unit 31, and the charger 26 is decoupled from the tower unit 30, as shown in figure 11. The tower unit 30 can be attached to the base tower unit 31 using conventional devices to form a tower. Once attached, the handling arm 42 of the loader 26 is detached from the strap 40 of the tower unit 30, thus reversing the coupling, as described with reference to figures 6 and 7.
    [0083] Although the tower unit 30 is shown installed in the base tower unit 31, it is realized that the tower unit can be installed directly on a foundation, such as the ocean floor, on site. In some cases, the foundation can be reinforced or provided with a structure to receive the windmill. The cargo handling system 100 can also be used to install the base tower unit 31, if present. The tower unit, foundation and / or other vertical components can be separated into smaller components or combined before installation. Other devices, such as pile drivers 19, can be provided to facilitate installation.
    [0084] The lifting platform 24 is then raised to suspend the nacelle 22 above the tower unit 30, as shown in figure 12. Figure 12 shows a case where the blades 32 in nacelle 22 extend outward beyond the platform legs 14. In order to place a nacelle 22 as it is in the standing tower unit 30, it is necessary to either remove the paddles 32 or move to rotate the nacelle 22. In one aspect, the nacelle 22 is rotated without removing the paddles 32. To allow rotation, the lifting platform 24, with the nacelle 22 in it, is raised to a position in such a way that the nacelle 22 can be rotated without contact between the platform legs 14 and the paddles 32.
    [0085] In one aspect, nacelle 22 can be rotated using plunger 28. Plunger 28 comprises a bearing that allows it to rotate and thus pivot nacelle 22 supported on it. Plungers 28 can also be configured to extend or retract for additional positioning control. Plunger 28 can be implemented using conventional mechanisms (for example, hydraulic / pneumatic / gear driven pistons, etc.). Figure 13 shows nacelle 22 after having been rotated to release platform legs 14. With nacelle 22 rotated, platform 24 is lowered to place nacelle 22 on tower unit 30. Nacelle 22 can optionally be rotated by plunger 28 before picking up and / or installing tower unit 30.
    [0086] Figure 14A shows nacelle 22 positioned and attached to tower unit 30. Figure 14B is a side view showing the paddle 32 being raised for attachment to nacelle 22. The paddle 34a is shown with a telescopic element 50 (for example, pneumatic, hydraulic, electric servo, etc.) configured to lift the blade 32 to the mounting position. The telescopic element 50 extends to move the blade rest 34a from a stowed position to an extended position for installing the blade 32 in the nacelle 22. The telescopic element 50 can also be configured to hold the blade 32 at an angle during mounting in a nacelle 22 configured to accept the paddle 32 at an angle. As shown, the telescopic element 50 comprises hinges 57 to allow extension of the blade rest 34a to the desired position.
    [0087] Figures 15 and 16 show close-up views of the turbine assembly in place with nacelle 22 (from figure 14A) removed. These figures represent the operation of work platforms 52. Nacelle 22 is not shown in these for reasons of clarity of explanation. As also shown in these figures, the tower unit 30 can optionally be installed prior to retrieval of nacelle 22 for installation.
    [0088] Figure 15 shows the work platforms 52 on the loader 26 in the established position to facilitate movement of the workers. The work platforms 52 shown extend over a portion of the loader floor about the tower unit 30. One or more such work platforms 52 can be provided in various positions around the load handling system 100 to provide a surface for workers. Figure 16 shows the work platforms 52 in the stowed position to allow the loader 26 to be pulled out of the tower unit 30. The work platforms 52 can be retracted, for example, by sliding the work platforms 52 over portions adjacent to the loader 26, or by rotating the work platforms to a lower position.
    [0089] Since the nacelle 22 is attached to the tower unit 30 and the final paddle 32 is attached to the nacelle 22, the rest of the paddle 34a is disconnected from the paddle 32, as shown in figures 17A and 17B. The paddle 34a is preferably configured with hinged locking mechanisms for quick release of the paddle 32. Once the paddle 32 is released, the telescopic element 50 can be moved from the extended position (figures 14A, 14B) to an adjacent collapsed position to tower unit 30.
    [0090] The lifting platform 24 is then lowered and attached to the strap 40 and the paddle 34a to remove the strap 40 and paddle 34a from the tower unit 30, as shown in figure 18. The lifting platform 24 can be coupled to the blade rest 34a using the handling arm in the same manner previously described with respect to figures 6 and 7.
    [0091] The loader 26 and blade rest 34a are then disconnected from the tower unit 30. The strap 40 is opened to release the strap from the tower unit 30. The handling arm 42 is then moved to the stowed position below the loader 26, thus reversing the movement, as described with respect to figures 10A and 10B.
    [0092] The paddle rest 34a is rotated to a retracted position under the loader 26, as shown in figure 19. The platform legs 14 are then retracted and the unit is lowered or lowered, ready to move to another case. With the platform legs 14 retracted and the base 10 "down", the installation is completed and the system 100 moves away from the base tower unit 31. With the wind turbine installed, the cargo handling system 100 is now in route to another installation site to repeat the process.
    [0093] Figures 20-24 show an alternative manipulator 37b for use with the cargo handling system 100. As shown in these figures, the alternative manipulator 37b is used to store and install a shovel 32. The manipulator 37b can be operationally connected in the loader 26 and moved around the system 100 via the loader 26 and lifting platform 24 in the same manner previously described with respect to the manipulator 37a and as shown, for example, in figure 9. In this version, the manipulator 37b has a rest of the alternative paddle 34b operably connectable to the arm 42 of the loader 26 in the same way that the manipulator 37a is connected as previously described with reference to figures 6 and 7.
    [0094] A detailed view of the manipulator 37b is shown in figures 21A-C. The paddle 34b has a strap with a paddle holder 65 at one end of it to receive one end of the paddle hub 32. The paddle rest 34b also has a paddle holder 67 at a distance from the paddle holder 65 for support the paddle 32 on the paddle 34b. The paddle holder 67 is shown with an open end for receiving the paddle.
    [0095] Figures 21B-C show the manipulator 37b with the paddle 32 removed. These figures represent the operation of the paddle grip 65. Preferably, the paddle grip 65 can be selectively and pivotally open to receive and / or release a paddle 32. The paddle grip 65 is movable between a closed position around the paddle 32 shown in figures 21A and 21B, and an open position shown in figure 21C. Preferably, the blade holder 65 and the blade holder 67 have surfaces that act as positionable feet on the base 10 for storing the blade therein.
    [0096] Once a paddle 32 is positioned on the manipulator 37b and attached to the loader 26, the paddle 32 can be transported via the loader 100 to a position adjacent to a nacelle 22 and the tower unit 30 for installation in it, as shown in figures 22-24. Tower unit 30 and nacelle 22 can be installed in tower unit 30, as previously described. In this configuration, nacelle 22 is installed without a paddle 32. Figure 22 shows the loader 26 raising the manipulator 37b to a height for paddle installation. Figure 23 shows the manipulator 37b being rotated via the extension of the arm 42 by the piston 49, in the same manner described with respect to figures 10A and 10B. Once the shovel 32 is in an upright position, the loader 26 is moved along the lifting platform 24 in such a way that the shovel 32 is placed in horizontal alignment with the nacelle 22 for installation, as shown in figure 24. The nacelle 22 can be rotated, and the process repeated for additional blades.
    [0097] Figure 25 shows an alternative handling system with an alternative lifting platform 24 "usable with the cargo handling system 100. The alternative lifting platform 24" is similar to the lifting platform 24, except that the lifting platform lifting 24 "has a single hole 25 through it to receive a single leg of platform 14. The lifting platform 24" is configured to run up and down along platform legs 14, as previously described here. In this configuration, the lifting platform 24 "is also rotatable around the leg of the platform 14, as shown in figure 26. The lifting platform 24" is preferably rotatable for transferring and / or transporting the windmill components in relation to the base and / or an adjacent surface, such as the transport system 200 of figure 27 (described below).
    [0098] Although the configuration of figure 25 shows the lifting platform 24 "with a single hole 25, it is clear that the lifting platform can be provided with one or more holes positioned around one or more platform legs 14. The lifting platform 24 "can be operationally (for example, articulated) connected to one or more legs of platform 14 and selectively releasable from it in such a way that the lifting platform 24" can be slidably movable along one or more platform legs 14.
    [0099] Aspects of the invention also imply a windmill transport system 200. Figure 27 shows an aspect of the system configured for offshore applications. In this figure, the transport system 200 moves to a location to supply a wind turbine tower assembly. The wind turbine tower assembly delivered by the transport system 200 includes a nacelle 22 and a tower unit 30 (with paddle 32). The transport system 200 advances towards a mobile turbine loader and load handling system 100 on site. The cargo handling system 100 can be the same cargo handling system 100 previously described with reference to figures 1-24, or another installation capable of receiving components of the windmill, such as nacelle 22 and tower unit 30 of the windmill. wind turbine tower assembly.
    [00100] The conveyor system 200 includes a conveyor 270 and a conveyor system 274. As shown in figure 27, conveyor 270 is a self-elevating boat suspended at sea 12 to transport the tower unit 30 and a nacelle 22 to the system cargo handling 100. The self-elevating boat has an upper surface to support the 274 transport system. Several handrails / stairs / walkways 238 can be arranged on the self-elevating boat 270 to allow and facilitate safe access and movement for employees. The self-elevating boat 270 includes three pillars or legs of the extendable boat 272. Some aspects can be implemented with more or less than three legs, depending on the layout and configuration of the self-elevating boat 270. The self-raising boat 270 is configured to remain afloat while the legs of boat 272 are suspended on the ocean floor.
    [00101] The transport system 274 is represented in figure 28A as a transfer platform 274 positioned on the self-elevating boat 270 to transfer the tower unit 30 (with paddle 32) and a nacelle 22 to the cargo handling system 100. The transport system 274 is shown in more detail in figures 28A-C. Figure 28A shows the transport system 274 with a nacelle 22 and tower unit 30 (with paddle 32) supported by it. The transfer platform 274 includes an upper support 276 with support legs 275 extending therefrom. Figure 28B shows the transfer platform 274 of figure 28A with the tower unit 30 (and paddle 32) removed. Figure 28C shows an upper support 276 of the transfer platform.
    [00102] The upper bracket 276 is configured to seat a conventional wind turbine nacelle 22. The upper bracket 276 has upper rails 273 to slide the nacelle 22 along the upper bracket 276. The slider 279 is provided to support the nacelle 22 on the rails 273 and to facilitate the sliding movement of the nacelle along the rails 273. The slider 279 can be the same as the slider 41 for sliding the nacelle 22, as previously described. The support legs 275 of the upper support 276 are operationally connected to the lower rails 277a to slide the upper support 276 along a surface of the lifter 270.
    [00103] A tower unit 30 is positioned on a lower support 269 below the upper support 276. The lower support 269 includes strap 240 to hold each tower unit in place on the lower support 269. Strap 240 can be the same strap 40a previously described to support a tower unit 30 and the paddle 32. The lower support 269 is slidably movable along lower rails 277b for transferring the tower unit 30. The lower support 269 can be, for example, a similar slide to the slider 41 to support the tower unit 30 on the rails 277b and to facilitate the sliding movement of the tower unit along the rails 277b. Various devices, such as slides, sliding bases, cylinders, bearings, rollers or other devices can be used for sliding movement along the rails 273, 277a, b.
    [00104] Each tower unit 30 has a single blade 32 with it held in place by a manipulator 237, with the strap 240 and a support or paddle 234. The manipulator 237 and paddle 234 can be the same as the manipulator 37a and blade rest 34a described above. This particular aspect of the invention is shown with each nacelle 22 equipped with a pair of paddles 32. Some aspects can be implemented with each tower unit 30 equipped with multiple handlers 237, paddles 234 and / or paddles 32. Other aspects may also be implemented with paddles 234 configured to contain multiple paddles 32.
    [00105] Although figures 27 and 28A show a nacelle 22 and a tower unit 30 with a paddle 32 loaded by the self-elevating boat 270 and supported by the transfer platform 274, it is noticed that one or more nacelles 22, paddles 32, units tower 30 and / or other items can be loaded by the self-elevating boat 270, supported by the transfer platform 274 and / or transferred by the transfer platform 274.
    [00106] Figure 29 shows the transport system 200 after it reaches the cargo handling system 100. The self-elevating boat 270 has mooring arms 280 to receive mooring tightening handles 180 in the cargo handling system 100. The self-elevating boat 270 is shown in an anchored position adjacent to the cargo handling system 100. The mooring arms 280 match the mooring clamping handles 180 to secure the self-elevating vessel 270 in the cargo handling system 100. Versed in the art realize that the self-elevating boat 270 can be held in place by other devices, such as a cable. Preferably, the self-elevating boat 270 is secured in a position in line with the cargo handling system 100 to facilitate the transfer of nacelle 22 and tower unit 30 to the cargo handling system 100.
    [00107] Continuing with reference to figure 29, once the self-elevating boat 270 is in position, the legs of boat 272 are extended to the ocean floor to secure the self-elevating boat 270 in position. The legs of the boat 272 are then used to lift or lift the self-raising boat 270 to the desired height for transfer. Preferably, the self-elevating boat 270 is positioned in such a way that the lower rails 277b of the transfer platform 274 are in alignment with base rails 282 on the base 10 of the cargo handling system 100. The cargo handling system 100 can be provided with base rails 282 shown in figure 29, or other devices capable of facilitating the transfer of the wind tower assembly. Winches, cranes or other mechanisms can also be provided to position the self-elevating boat 270 and / or cargo handling system 100 to perform various operations, such as transfers.
    [00108] Figure 30 shows the self-elevating boat 270 raised via the legs of the boat 272 to a height for transferring the tower unit 30. With the transport system 200 in place adjacent to the cargo handling system 100, the lifting platform 24 can be positioned to allow receipt of the tower unit 30 from the lifeboat 270. As shown in figure 30, the lifting platform 24 is raised to a position to allow the transfer of the tower unit 30.
    [00109] As shown in figure 31, the tower unit 30 is slidably moved along the lower rails 277b of the lifeboat 270 and on the base rails 282 of the base 10. A slide 271 is shown passing along the lower rails 277b for the base rails 282 to load the tower unit 30 from the lifeboat 270 on the base 10. Other devices, such as a winch, rollers, etc., can be used to facilitate the transfer of the tower unit 30 over the rails 277b, 282. The tower unit 30 is received by the loader 26. The loader 26 can be coupled to the manipulator 237 of the tower unit 30 via strap 40, as previously described.
    [00110] The tower unit 30 can then be transported around the cargo handling system 100 by the loader 26 using the lifting platform 24. As shown in figure 32, the lifting platform 24 moves the tower unit 30 around of the cargo handling system 100. The lifting platform 24 can be raised and lowered and / or the loader 26 moved back and forth to move the tower unit 30 in the desired manner.
    [00111] The tower unit can be moved to a location close to the base 10. The tower unit 30 is then released on the base 10, as shown in figure 33. The tower unit 30 can be detached from the loader 26, as previously described. In some cases, tower units 30 can be transferred to storage or another location in the desired manner.
    [00112] The lifting platform 24 and the self-raising boat 270 can now be positioned for transferring nacelle 22 to the cargo handling system 100. As shown in figure 34, the loader 26 of the lifting platform 24 is moved to the position for alignment with the upper rails 273 of the upper support 276. The self-elevating boat 270 is then lifted along the legs of the boat 272 to a raised vertical position for transfer, as also shown in figure 34. The loader 26 of the lifting platform 24 is then moved to align with the upper support 276 to receive nacelle 22.
    [00113] The upper support 276 then moves to an extended position in such a way that the upper rails 273 are adjacent to the loader 26 of the lifting platform 24, as shown in figure 35. Nacelle 22 is slidably moved by the upper support 276 along lower rails 277a of the self-elevating boat 270 and to the loader 26, as shown in figure 35. A slide 279 is provided to load the nacelle along rails 273 to the loader 26.
    [00114] Figure 36 shows nacelle 22 as received by charger 26. Charger 26 can be adapted to receive slider 279. Alternatively, nacelle 22 can be transferred to the charger without slider 279. Nacelle 22 and / or tower unit 30 can be moved to the cargo handling system 100 using any suitable device (for example, via a winch mounted on the upper and / or lower supports 276, 269). In some aspects of the invention, the supports 276, 269 and / or cargo handling system 100 can be configured with conventional gear / track systems to allow movement or extension of the components to facilitate transfers.
    [00115] Once the transfer is complete, the transport system 200 can be retracted from the cargo handling system 100. The upper support 276 is moved back to its original retracted position on the self-elevating boat 270, as shown in figure 37 The transfer process can be repeated in such a way that one or more nacelles 22, tower units 30, paddles 32 and / or other components or devices can be transferred by the transport system 200 to the cargo handling system 100, and / or from it. In some cases, it may be desirable to remove items from the cargo handling system 100 to the self-elevating boat 270. The transfer process can be reversed to provide for such removal.
    [00116] The self-elevating boat 270 is lowered along legs of boat 272 to sea level 12, as shown in figure 38. The legs of boat 272 can then be raised to their original position, as shown previously. The transferred nacelle (s) 22, tower unit (s) 30 and / or paddle (s) 32 can be positioned around the cargo handling system 100 in the desired manner, as previously described. Components can be transferred and / or stored using manipulators 37a, 37b, 237a and / or other devices. One or more nacelles 22, tower units 30 and / or paddles 32 can be transported together or separately around the cargo handling system 100. Nacelles 22, tower units 30 and / or paddles can then be stored and / or installed in the manner previously described here.
