Maritime platform for technical facilities

The invention relates to a maritime platform for technical Facilities.

Such platforms are known as so-called drilling rigs and consist of a pontoon stilted on the seabed.

The disadvantage of such Beohr islands is that their load-bearing capacity due to the Aufstelzung is limited and that the drill pipe is exposed to the action of considerable external forces is. If one wants to switch off the influence of the current and waves on the platform, it must be correspondingly high To be raised above sea level. With the enlargement however, the influence of wind pressure increases with the height of the stilts.

The object of the invention is to eliminate these disadvantages.

The maritime platform consists of a floating part 1 and a lower anchor part 2, the latter on the seabed 3 is seated in a region 4 that has been leveled beforehand and is attached.

Between the floating part 1 and the anchor part 2 is a Deformable layer 5 arranged in order to ensure an even distribution of the contact pressure between the floating part 1 and the anchor part 2 to reach. This layer can be made of gravel, rubber, wood and other materials that provide good support for the floating parts 1 on the anchor part 2 guaranteed. To prevent lateral discharge of the deformable Material, the bottom of the floating part 1 can have a continuous, protruding edge 6 that extends into the area of the anchor part 2 is sufficient and thus represents a limit for the layer S.

To the bottom of the floating part 1 from premature wear is to be protected in particular by friction with the layer 5 the bottom of the floating part x 1 with an outer cover

7 provided.

Dex floating part 1 and the anchor part 2 can each have one single support surface or several mutual support surfaces have that are flat and parallel to each other.

In Fig. 3, an outer part is shown with an edge threshold

8 is provided, the removal of the deformable layer 5, e.g. gravel, prevented. The floating part 1 also has an outer protective layer 7.

The floating part 1 is equipped with ballast tanks in such a way that that when these tanks are emptied, the part can float and be moved, be it in tow, be it by self-propulsion. In the case of flooded ballast tanks, however, sits

the floating part on the anchor part 2. The amount of the Ankertcils is chosen so that when the ballast tanks are lightened the floating part can be arranged above it, while with full ballast tanks de3 floating parts can be arranged with it sufficient pressure to prevent movement of the floating part under the influence of external loads.

The height of the anchor part 2 depends on the water depth. If, as shown in Fig. 4, because of the shallow Waeaertiefe the anchor part 2 is attached directly to the bottom of the floating part 1, it simultaneously provides its protective layer or the protective layer acts as an anchor part. In these fills the weight of the floating part is at flooded ballast tanks should be chosen so that movements of the two parts due to the action of external loads be prevented. The depth of the floating tell, on the other hand, is not enough to dig so that the sea level 9 is below the ceiling of the floating part.

From Pig-5 it can be seen that the floating part 1 has support surfaces may have for the anchor part 2, which is not the entire Occupy the bottom of the floating part. For example, elements 1o can protrude from the bottom of the floating part 1 / which have a lower surface that is flat and parallel to the surface of the anchor part 2 and a support for the represents floating part on the anchor part. Fig. 6 shows that these elements 1o can be carriers, between their flanges and the anchor! 1 2 the deformable layer is arranged is, which consists of wooden elements 11, between which a seal 12 is arranged. The elements Io can, for example be arranged in two mutually perpendicular directions, oo that cavities 13 arise, their watertightness with the help of the seals 12 is achieved. To these catfish the cavities 13 can be made accessible. In the

right side of Fig. 6 it can be seen that the bottom of the floating part 1 can be flat, the anchor part a has protruding part 14, the upper surface of which is flat and parallel to the bottom of the floating part 1 and a support surface fllr forms the floating part 1 on the anchor part 2. These projecting parts can be arranged in two mutually perpendicular directions, so that cavities 13 are formed. Between the protruding parts 14 and the bottom of the floating Part 1 a deformable layer is provided, which e.g. can consist of wooden elements 11, between which a Seal 12 is arranged to make cavities 13 watertight and thus to make it accessible.

The cavities 13 can through openings in the floating part or be accessible in the anchor part.

In the embodiment according to Figure 7, the anchor part consists of three Elements 15, 16 and 17 which are placed against one another and, as can be seen in FIGS. 8 and 9, are provided with watertight cavities 18 that can be flooded and unloaded. The volume of these cavities is sufficient around each of the anchor parts Keep the constituent element floating 7-u when the ballast tanks are lightened. On each of the elements forming the anchor part a floating part can be arranged. According to FIGS. 8 and 9, the floating parts can be combined to form a platform will.

The cavities 18 of the elements forming the anchor part are connected to each other and can be provided with a device generally designated 19 for flooding and lightening " to allow the anchor part to float) or to the previously prepared one Lower layer 4 on the sea floor. The zones of the anchor part 1 that form the support surface are shown in FIG. enclosed by a wall-like projection 8 to the out Gravel or other material existing layer 5 in the predetermined space

to keep. In Pig. 7 3lnd several such walls 8 can be seen, which are the support surfaces for the floating parts on the anchor parts 15, 16 and 17 limit.

In Fig. 1o and 11, the protective layer 7 is shown on the bottom of the floating part.

From Fig. 12 it can be seen / that the protective layer can for example consist of a concrete slab 22 with bars is reinforced, which in turn are welded to angle brackets 21. A seal 23 is provided on the wall-like projection 8, which surrounds the support zones of the anchor part, around the space for the deformable layer 5 as well as that accessible via the hollow column 24 through the bottom of the floating part 1 Waterproof space 2o.

The cavities 18 of the Ajiker part can also service aisles 25 exhibit.

According to the proposed system, it is possible to use the floating and manufacture the anchor parts far away from their place of use and then drag them there. With the help of the cavities 18 can be the anchor part with the floating Part to be brought to swim. The anchor part acts in this case as a floating dock. In this way, various repairs can be facilitated or made possible, but the platform can also be moved from one to another in this way Application area are brought.
