         8 ) The component according to  claim 1 , wherein the component comprises at least two base plates each with at least one cover plate arranged thereon, wherein adjacent base plates with the cover plates arranged thereon are connected in a butt joint. 
     
     
         9 ) component according to  claim 1 , wherein the component has at least one longitudinal stiffening element and transverse stiffening element as stiffening elements. 
     
     
         10 ) The component according to  claim 1 , wherein the stiffening element on the one side and the cover plate and the damping layer on the other are at a predefined distance from one another in the connection area. 
     
     
         11 ) The component according to  claim 1 , wherein the component is a supporting structural component of a ship, in particular a component of a ship's hull, a ship's wall, a ship's bulkhead, a ship's ventilation duct and/or a ship's deck. 
     
     
         12 ) Use of a component according to  claim 1  in shipbuilding, in particular for a supporting ship structure, for a ship's hull, for a ship's wall, for a ship's bulkhead, for a ship's ventilation duct and/or for a ship's deck. 
     
     
         13  A method for the manufacture of a component, in particular according to  claim 1 , the method comprising:
 providing at least one base plate; 
 providing at least one stiffening element; 
 arranging at least one cover plate on the base plate, wherein a damping layer is provided between the base plate and the cover plate; 
 connecting the stiffening element to the base plate and the cover plate on the cover plate side in a connection area of the base plate, wherein the connection area is free from the cover plate and the damping layer at least in sections. 
 
     
     
         14 ) The method according to  claim 13 , wherein the stiffening element is connected in a firmly bonded manner, in particular by means of welding, to the base plate and the cover plate. 
     
     
         15 ) The method according to  claim 13 , wherein the method further comprises:
 chamfering of the stiffening element on one side or preferably on both sides on the side of the stiffening element that faces the base plate before the connection of the stiffening element to the base plate and the cover plate.   
     
     
         16 ) The method according to  claim 13 , wherein the method further comprises:
 fixing of the stiffening element to the base plate in places, in particular before arranging the cover plate on the base plate.   
     
     
         17 ) The method according to  claim 13 , wherein the method further comprises:
 providing at least one cover plate already provided with a damping layer.
