The 1 and 2 show a ship 100 More specifically, a jack-up barge with a guide frame 200 for vertically guiding three foundation piles when erecting a foundation of an offshore wind turbine according to a particular embodiment of the invention and a stacking, erecting and lowering device 300 for horizontal stacking of foundation piles on the ship 100 , vertical erection of the foundation piles next to the ship 100 and lowering or sinking the foundation piles onto a ground or subsoil, such as a solid seabed 400 for erecting a foundation of an offshore wind turbine according to a particular embodiment of the invention in side view and top view, respectively. Since the ship 100 is currently in transit, is the guide frame 200 at an outer edge 110 at the stern of the ship 100 is mounted vertically pivotable about a fastening device, pivoted upwards (folded up) and locked and are the legs 102 . 104 . 106 and 108 of the ship 100 retracted. For the same reason is a stacking, erection and lowering device 300 associated crane 302 collapsed. As reflected by the 2 shows, has the stacking, erection and lowering device 300 two in the longitudinal direction of the ship 100 spaced bearing blocks 304 and 306 as well as one at a distance and at the outer edge 110 arranged Aufrichtsattel 308 on. The bearing blocks 304 and 306 , the righting saddle 308 and the guide frame 200 are arranged such that a foundation pile (not shown) in the stacking, erecting and lowering device 300 in the longitudinal direction of the ship 100 and in a guide of the guide frame 200 erected and can be lowered or sunk into it (see also 3 ).

The 3 and 4 , where in 4 the crane arm is omitted, show the ship 100 in a "jacked up" condition. These are the legs 102 . 104 . 106 and 108 on the solid seabed 400 lowered and secured there. The ship 100 is done by means of the legs 102 . 104 . 106 and 108 depending on the wave height of 1.5 to 2.5 m from the water 402 lifted. Furthermore, the crane 302 set up and fold down the guide frame 200 used. It is now in the working position. In 4 are the staple arms of the guides, of which only the Klammerarmpaare 202 and 204 . 206 and 208 such as 210 and 212 the three upper guides are shown in the closed state. However, this is not the starting point for positioning foundation piles in the guides.

In the 5 and 6 is just a foundation pile 406 by means of the crane 302 from a delivery barge 500 on the stacking, erection and lowering device 300 transhipped. Another foundation pile 408 is already on the stacking, erecting and lowering device 300 ,

In 7 is already one of the three foundation piles, here with 410 referred to, in the solid seabed 400 Installed. Another foundation pile, here with 412 is also already with the help of the guide frame 200 and the stacking, erection and lowering device, from here the bearing blocks 304 and the righting saddle 308 are marked on the solid seabed 400 has been lowered and is currently using a at the end of a hoist rope 310 of the crane 302 fixed hydraulic ram 312 in the solid seabed 400 anchored.

The 8a to 8e show the process of stacking three foundation piles, here with 414 . 416 and 418 referred to, on the stacking, erecting and lowering device 300 , more precisely on one 304 the two bearing blocks 304 and 306 , In 8a is by means of the crane 302 (not shown) a foundation pile 414 in horizontal orientation on the bearing block 304 arranged in a first storage position. By means of a in the bearing block 304 provided hydraulic transverse displacement device (not shown) is the foundation pile 414 moved transversely to its longitudinal direction (see 8b ). Then the foundation pile becomes 414 by means of a hydraulic lifting device 314 raised to an upper storage position (see 8c ). A subsequent foundation pile 416 is also by means of the crane 302 (not shown) deposited in the first storage position and then moved by means of the hydraulic transverse displacement device to the left (see 8d and 8e ). Finally, a third foundation pile 418 also by means of the crane 302 (not shown) discontinued in the first storage position. The bearing block 304 and the bearing block 306 store three foundation piles at the same time 414 . 416 and 418 the latter being arranged at a 90 ° angle. Unstacking the foundation piles 414 . 416 and 418 takes place in reverse order to stacking. Starting from the 8e thus becomes the foundation pile 418 first moved and erected in its longitudinal direction (see 9a to 9e ), then the foundation pile 416 shifted to the right and then also moved in its longitudinal direction and erect and finally the foundation pile 414 lowered, then moved to the right and then moved in its longitudinal direction and erect.

Based on 9a to 9e There are further details for erecting and lowering or sinking foundation piles by means of the stacking, erecting and lowering device 300 , In 9a is an end 418a of in 8e shown foundation pile 418 by means of a hydraulic longitudinal displacement device, not shown, already in the direction of Aufrichtsattel 308 been pushed. In 9b is the foundation pile 418 moved even further to the left and on the Aufrichtsattel 308 been pushed and in his open end 418a already a retaining clip 316 , also known in English as "Upending hook", has been inserted. At the other end 418b of the foundation pile 418 is already a righting tool 318 , in English also called "Upending tool" has been attached. Said erection tool 318 hangs on the hoist rope 310 of the crane 302 (Not shown). As already in the 9a and 9b indicated and also in the 9c shown is the retaining clip 316 on a wire rope 320 attached to a cable winch (not shown). The crane 302 (not shown) raises the foundation pile 418 about its end 418b with the erection tool 318 at. At the end 418a secures the retaining clip 316 the foundation pile 418 against uncontrolled slipping over the outer edge 110 , also called mirror edge, of the ship 100 , The crane 302 raises in synchronism with the lowering of the retaining clip 316 via the cable winch (not shown) the foundation pile 418 in a vertical position above the water (not shown).

As reflected by the 10a and 10b results are, more precisely, the foundation piles 418 . 416 and 414 one after the other over the saddle 308 set up and in the in 10a with 1st, 2nd and 3rd named positions by means of the crane 302 lifted. More specifically, each of the foundation piles 418 . 416 and 414 individually via the stacking, erecting and lowering device 300 raised, raised to position 1, 2 or 3, by means of the guide frame 200 secured in vertical position and by means of the ram 312 in the seabed 400 anchored.

10a also shows in principle the guide frame 200 in the initial situation, that is with open bracket arms. In 10b are already all three foundation piles 414 . 416 and 418 installed so that the clamp arms are closed. The arcuate arrows show the closing directions of the staple arms.

To the 11 and 12a to 12c carry out the following: If a foundation pile 414 . 416 or 418 through the crane 302 is lifted into position, the clamp arms of the guide frame 200 hydraulically closed and secured by hydraulic locks (not shown). There are still no leadership roles 232 at the foundation pile (see 12a ). After that, the leadership roles 232 moved hydraulically to the foundation pile (see 12b ). As a result, the foundation pile is brought into an absolutely vertical position. As a result, then the retaining clip 316 be removed. Following this, the foundation pile is lowered by lowering the crane 302 lowered or drained until the foundation pile sinks by its own weight in the soft seabed and the crane gets loose. Then the erection tool becomes 318 taken off and by the crane to the deck of the ship 100 stored. The crane 302 then take the rammer 312 and place them on the foundation pile, around the foundation pile to the planned depth in the solid seabed 400 to sink. Once the foundation pile firmly in the seabed 400 is rammed, the guide rollers are retracted to protect the hydraulics from unnecessary shocks. The guide rollers are additionally equipped with a hydraulic pressure accumulator to ensure a scheduled retraction of the guide rollers in case of emerging shocks (see 12c ). The hydraulic accumulator is designed to increase the longevity of the guide frame 200 ensure and protect against premature wear.

In the 13a and 14a are on top th of the guide frame shown in the preceding figures 200 shown with open or closed clamp arms. The 13b and 14b contain corresponding perspective views. How best to use the 14b results, the guide frame points 200 Steel two superimposed spaced, interconnected guide frame frame 216 and 218 each with three guides 220 . 222 and 224 respectively. 226 . 228 and 230 on. The guides of the upper frame 216 aligned with a respective associated guide of the lower guide frame frame 218 in pairs, namely guides 220 and 226 , Guides 222 and 228 as well as guided tours 224 and 230 , Both guide frame frames 216 and 218 are at least essentially triangular, with the guides 220 . 222 and 224 respectively. 226 . 228 and 230 are arranged at the three corners of the triangle. On one side of the triangle is the upper guide frame 218 two spaced mounting straps 232 respectively. 234 on, by means of which the guide frame 200 at the outer edge 110 of the ship 100 vertically pivotable fastened. Each of the guides 220 . 222 . 224 . 226 . 228 and 230 has two connectable clip arms 220a . 220b . 222a . 222b , ... 230a . 230b on. At the guides 220 and 224 such as 226 and 230 is always one of the staple arms, namely 220a . 224b . 226a and 230b stationary, while the other by means of a hydraulic 220c . 224c . 226c respectively. 230c is horizontally pivotable to close or open the respective bracket arms and thus the respective leadership. Only the guides 222 respectively. 228 have two by means of a respective hydraulic 222c horizontally swiveling clamp arms. Said clamp arms 220a . 220b . 222a . 222b , ..., 230a . 230b are also, preferably hydraulically, locked together and unlocked. On each of the bracket arms 220a . 220b . 222a . 222b . 224a and 224b the guides 220 . 222 and 224 is a leading role, of which only one with 232 is arranged, as well as in the 12a is shown. At the bottom guides 226 . 228 and 230 is in each case such a leadership role, of which only one with 272 is marked on the underside of the staple arms 226a . 226b . 228a . 228b . 230a and 230b arranged. Said leadership roles are, as already in connection with the 12a to 12c called, from a rest position in which they are not in contact with a foundation pile, pivotable in a guide position in which they rest against a arranged in the respective guide foundation pile or press.

The in the 15 shown embodiment of a guide frame 200 differs from the guide frame shown in the preceding figures in that a kind of bridge 234 for workers between a leg of the guide frame 200 is provided to an opposite tip of the triangular guide frame frame. As said thigh 236 adjacent to the ship 100 lies, over the bridge 234 a worker in an easy way to from the ship 100 facing away leadership 224 reach.

As the 16 and 17 show, points the Aufrichtsattel 308 two spaced bearing surfaces 322 and 324 for a foundation pile (in 17 dashed lines), between which space for the retaining clip 316 is. The latter is hook-shaped, so that it can engage in the end of the foundation pile. Said retaining clip 316 is by means of the attached wire rope 320 over the saddle 308 and the outer edge 110 of the ship 100 can be lowered down into the water.

As can be seen from the synopsis of 18 and 19 indicates the erecting tool 318 a clamping device 318a for clamping the edge of the upper end of a foundation pile 418 on. In the lower area, the erection tool 318 also a stop 318b to hold the foundation pile vertically.
