COVER FOR A COMPONENT OPENING OF A COMPONENT, IN PARTICULAR AN OFFSHORE STRUCTURE

Abstract

The invention relates to an assembly (1) comprising: a hollow component (2) with a component opening (3), a cover (4), by means of which the component opening (3) is closed, and a fan (5) for ventilating the interior (6) of the component (2), wherein the fan (5) is pivotally secured to the cover (4). The component opening of the component (2) can be closed by the cover (4) so that the interior (6) of the component (2) is protected against external influences. The formation of mold in the interior (6) of the component (2) can be prevented by means of the fan (5). Because the fan (5) is pivotally held on the cover (4), the interior (6) of the component (2) is particularly readily accessible.

Description

[0056] The invention will be described in greater detail in the following text on the basis of the figures. The figures show one particularly preferred exemplary embodiment, to which the invention is not restricted, however. The figures and the proportions are shown in them are merely diagrammatic. In the figures:

[0057] FIGS. 1a to 1c show three stages of a method according to the invention for assembling an offshore wind power plant,

[0058] FIG. 2a shows a side view of a part of the arrangement from FIG. 1a,

[0059] FIG. 2b shows a plan view of what is shown in FIG. 2a,

[0060] FIG. 3a shows a side view of a part of an arrangement from FIG. 1a in a further state, and

[0061] FIG. 3b shows a plan view of what is shown in FIG. 3a.

[0062] FIG. 1 illustrates a method for assembling an offshore wind power plant as an offshore construction 7. FIG. 1a illustrates a step a), in which a hollow pile 8 is anchored in a seabed 13, with the result that a component opening 3 (shown in FIG. 1b) on an end side 9 of the pile 8 lies above a waterline 14. The pile 8 is a component 2. The component opening 3 is closed by way of a covering 4, a fan 5 for ventilating an interior space 6 of the pile 8 being fastened pivotably to the covering 4. The interior space 6 of the pile 8 is protected by way of the covering 4. At the end of step a), the arrangement 1 which is shown in FIG. 1a is present. The arrangement 1 comprises the pile 8, the covering 4 and the fan 5.

[0063] FIG. 1b illustrates a step b), in which the covering 4 is removed. To this end, the covering 4 can be split and subsequently disposed of.

[0064] FIG. 1c illustrates a step c), in which a tower structure is mounted as a construction structure 15 on the pile 8. As a result, the arrangement 1 becomes an offshore construction 7. The previously existing component opening 3 is closed in the long term by way of the tower structure. The pile 8 is a foundation structure, anchored in the seabed 13, for the offshore construction 7.

[0065] FIG. 2a shows an enlargement of a part of FIG. 1a. The pile 8 is shown as the component 2 with the end side 9 which is arranged above the waterline 14. On the end side 9, the pile 8 has the component opening 3 (shown in FIGS. 1b and 2b) which is closed by way of the covering 4. The covering 4 has a rod assembly 12 which is covered with a tarpaulin 11. Only one tarpaulin segment with the designation 11 and one rod with the designation 12 are provided by way of example. The fan 5 is arranged on an axis A of the component opening 3. The axis A is at the same time an axis of the component 2. The covering 4 has a ring plate 10. A ventilation opening 17 is configured centrally in the ring plate 10. The interior space 6 of the pile 8 can be ventilated by way of the fan 5 via the ventilation opening 17 in the covering 4. This is possible in that operating position of the fan 5 which is shown in FIG. 2a.

[0066] FIG. 2b shows a plan view of what is shown in FIG. 2a. The covering 4 with the tarpaulin 11 and the rod assembly 12 can be seen. Only one tarpaulin segment with the designation 11 and one rod with the designation 12 are also provided here by way of example. The ventilation opening 17 is configured centrally in the ring plate 10. Furthermore, component opening 3 is illustrated. This extends over the entire end side 9 of the pile 8, that is to say over the entire circle provided with the designation 3 in FIG. 2b.

[0067] FIG. 3a shows the arrangement 1 from FIG. 2a in a further state. In said figure, the fan 5 is pivoted away out of the operating position which is shown in FIGS. 2a and 2b. In addition, a winch apparatus 16 is mounted outside the covering 4 on an edge of the component opening 3 of the pile 8. For the sake of clarity, the axis A of the component opening is not illustrated here. The interior space 6 of the pile 8 is accessible for the winch apparatus 16 via the ventilation opening 17 in the covering 4. This is indicated in so far as a cable 18 of the winch apparatus 16 is shown which is routed through the ventilation opening 17 into the interior space 6 of the pile 8. The cable 18 is fastened to a winch (not shown) of the winch apparatus 16. A hook 19 is indicated at the other end of the cable 13, via which hook 19 loads can be received. The winch apparatus 16 can be used, in particular, to pull in the cable between steps a) and b).

[0068] FIG. 3b shows a plan view of what is shown in FIG. 2a.

[0069] The component opening 3 of the component 2 can be closed by way of the covering 4, with the result that the interior space 6 of the component 2 is protected against external influences. Mold formation in the interior space 6 of the component 2 can be prevented by way of the fan 5. The interior space 6 of the component 2 is particularly satisfactorily accessible by virtue of the fact that the fan 5 is held pivotably on the covering 4.
