Anchoring for floating bodies that can be used at sea

The present invention relates to an anchorage for large floating bodies to be anchored at sea, for example oil tanks in the shallow sea.

Conventional floating bodies of this type are, as FIG. 1 shows, with lines b on the pier or the anchoring post a anchored; or, as FIG. 2 shows, they are anchored to the sea floor in a floating manner with anchors d and anchor chains £.

In the first case (Figure 1), however, the number of anchor lines b and their diameter must be used when using ever larger floating bodies get bigger and bigger. In addition, the length of the anchor lines must be adapted to the change due to the tidal range. Such anchoring therefore requires a great deal of work and time for fastening, monitoring and the maintenance of the anchor lines.

In the second case (Figure 2), with the anchor d and anchor chains £ are used, with increasing floats the maintenance and monitoring of anchor chains e in the same Measure, as with the use of anchor lines b, more and more difficult. Furthermore, there is the installation of anchors on the seabed difficult and the anchoring performance poor.

The object of the present invention is an anchoring arrangement to create that allows easy anchoring, ensures good performance in the attachment of floating bodies and can be easily maintained and monitored.

This task is solved by anchoring posts installed on the seabed on which a large number of pressure fenders are attached are attached, and by an anchor chain, which is connectable with its free end to the floating body and the other End via a pull fender, which is between a movable counter plate and one connected to the anchoring post fixed support is arranged, is connected. The pressure fenders and pull fenders are made of an elastic material, preferably made of rubber.

Further refinements of the invention are described in the following description and the subclaims.

The invention is described below with reference to the accompanying drawings described in more detail, the figures show in detail:

FIG. 1: a perspective view of a conventional floating body anchorage;

FIG. 2: another embodiment of a conventional floating body anchor;

FIG. 3: a perspective top view of a floating body anchor according to the invention;

FIG. 4: sectional view along the line IV-IV according to FIG. 3;

FIG. 5: Sectional view along the line V-V according to FIG. 3.

In Figures 3 to 5, a rectangular one that can be used at sea Floating body 1 is shown, which is anchored by means of anchoring posts 2 and 3, which are erected on the seabed B. On the anchoring posts 2 and 3 are pressure fenders made of elastic Material, for example made of rubber or the like. Attached, preferably on 3 sides of the floating body to be anchored 1 such fenders 4 and 5 are provided.

Two opposite sides of the float 1 are between Druckf endern 4 and 4, which are on opposite sides Anchoring posts 2 and 2 are attached. As FIG. 4 shows, it is between the floating body 1 and the fenders 4 left a certain distance. The other side of the floating body 1 is connected to the anchoring post 3, namely via a pulling fender 6 and an anchor chain 7, the floating body bring them into contact with the pressure fenders 5.

The anchor chain 7 is at its free end with a connecting piece 7 a, while the floating body 1 is provided on one side with a slot device 8 for receiving the connector 7 a is provided. A fixed support part 3 a is firmly connected to the anchoring post 3. The other end of the Anchor chain 7 is connected to a movable actuator 9 through the fixed support part 3a. A float draw fender 6 made of elastic material, for example rubber, is provided between the rear side of the support part 3 a, which is connected to the anchoring post 3, and the movable actuator 9. The connection piece 7a is coupled to the guide groove of the slot device 8 and can be in the guide groove and be moved while it is against the elasticity of the pull fender 6 pulls on the floating body 1.

With the aid of the device described above, the float 1 can be securely anchored in an almost fixed position by the pressure fenders 4 and 5 with which the anchoring posts 2 and 3 are equipped and by the pulling fender 6. For anchoring, the floating body 1 is simply guided in such a way that that three of its sides are surrounded by the anchoring posts 2 and 3, then the end of the anchor chain 7 with his Connecting piece 7a inserted into the guide groove of the slot device 8 and thus connected to the floating body 1; the anchoring can therefore be done extremely simply and easily.

If the float 1 due to ebb and flow or moved up and down by swell, he can do this movement without

Hindrance follow, since the connecting piece 7a can move relatively in the guide groove of the slitting device B.

Although only one pull fender in the present embodiment 6, a plurality of them may be provided along the longitudinal side of the floating body 1. In In this case, the floating body 1 can be adequately held in its position by anchors, if only at one Side connectors are provided and are connected with pull fenders.

As already described in more detail above, the floating body anchoring according to the present invention can be connected to the anchoring post 3 as an elastic body between the movable counter plate 9 and the back of the fixed support 3a with a pressure end 5, a normal elastic body. The present invention has increased attachment capability, ease of anchoring, and ease of maintenance and control of the marine anchoring system.
Furthermore, in the present invention, the anchor chain 7 is protected from overstretching by the damping of the elastic pull fender 6; accordingly, the dimensions of the anchor chain 7 can be reduced compared to conventional anchors.
