Device for scour protection of offshore structures

Abstract

A device for scour protection of offshore structures includes one or more elastic plates made of rubber and connected to each other, and weight elements which are fastened on the plates by fasteners.

1 . Apparatus ( 1 ) for scour protection of offshore constructions ( 2 ), which comprises one or more elastic panels ( 3 ) composed of rubber and weight elements ( 4 ) that are fastened onto the panels ( 3 ) by means of fastening means. 
     
     
         2 . Apparatus ( 1 ) according to  claim 1 , wherein the elastic panel ( 3 ) or the elastic panels ( 3 ) composed of rubber have a thickness of one to two centimeters and/or the weight elements ( 4 ) are fastened onto the elastic panel ( 3 ) or the elastic panels ( 3 ) at the edge region of the apparatus ( 1 ). 
     
     
         3 . Apparatus ( 1 ) according to  claim 1 , wherein the elastic panel ( 3 ) or the elastic panels ( 3 ) connected with one another form a disk with a circular or approximately circular contour, at the center point of which the offshore construction ( 2 ) is disposed. 
     
     
         4 . Apparatus ( 1 ) according to  claim 1 , wherein the radius of the apparatus ( 1 ) is about three times as long as the radius of the offshore construction ( 2 ) in the plane in which the apparatus ( 1 ) is disposed. 
     
     
         5 . Apparatus ( 1 ) according to  claim 1 , wherein the weight elements ( 4 ) have an essentially rectangular base surface, the longitudinal axis of which points in the direction of the offshore construction ( 2 ), in each instance. 
     
     
         6 . Apparatus ( 1 ) according to  claim 1 , wherein the weight elements ( 4 ) consist essentially of metal. 
     
     
         7 . Apparatus ( 1 ) according to  claim 1 , wherein the weight elements ( 4 ) have the shape, in longitudinal section and/or in transverse section, of an equilateral, symmetrical trapezoid, wherein its corners are preferably rounded off. 
     
     
         8 . Apparatus ( 1 ) according to, wherein the weight elements ( 4 ) have an indentation ( 9 ) on the underside, which is domed inward, in concave manner, in cross-section. 
     
     
         9 . Apparatus ( 1 ) according to  claim 1 , wherein at least one flexible reinforcement ( 17 ) is provided, which comprises a reinforcement profile ( 19 ) and a reinforcement wall ( 20 ) disposed above the reinforcement profile ( 19 ), wherein the reinforcement wall ( 20 ) forms a closed cavity ( 21 ) that is filled with a medium.
