What is claimed is: 
     
         1 - 12 . (canceled) 
     
     
         13 . An arrangement to dampen an impact of a pipe or a set of pipes falling down from a deck, the arrangement comprising:
 a first set of bars each of which is bent; and   a bottom plate configured to form a receptacle for the pipe or the set of pipes falling down from the deck,   the arrangement being configured to be connectable to the deck.   
     
     
         14 . The arrangement as recited in  claim 13 , wherein the arrangement further comprises a second set of bars. 
     
     
         15 . The arrangement as recited in  claim 14 , wherein each of the second set of bars is bent. 
     
     
         16 . The arrangement as recited in  claim 14 , wherein the first set of bars and the second set of bars together create a step-wise dampening effect. 
     
     
         17 . The arrangement as recited in  claim 14 , wherein,
 the receptacle is formed around a circumference, and   the first set of bars and the second set of bars are arranged so as to have a spaced-apart relationship around the circumference.   
     
     
         18 . The arrangement as recited in  claim 14 , wherein each of the first set of bars and the second set of bars comprises at least one bar. 
     
     
         19 . The arrangement as recited in  claim 14 , wherein each of the first set of bars and the second set of bars comprises four bars. 
     
     
         20 . The arrangement as recited in  claim 14 , wherein each of the first set of bars and the second set of bars comprises a plurality of bars. 
     
     
         21 . The arrangement as recited in  claim 20 , wherein each of the first set of bars and the second set of bars comprises an equal number of bars. 
     
     
         22 . The arrangement as recited in  claim 13 , further comprising a frame configured to be connected to the deck. 
     
     
         23 . The arrangement as recited in  claim 22 , wherein the frame is connected to the deck and to the first set of bars. 
     
     
         24 . The arrangement as recited in  claim 13 , further comprising a wave protection device for the first set of bars. 
     
     
         25 . The arrangement as recited in  claim 22 , wherein the wave protection device comprises a structure configured to surround the first set of bars. 
     
     
         26 . The arrangement as recited in  claim 13 , wherein the first set of bars are made of steel. 
     
     
         27 . The arrangement as recited in  claim 26 , wherein the steel is an austenite composition.
