Abstract

A marine structure comprises a supporting member adapted to be located at least partially immersed in water. The supporting member comprises a wall at least partially delimiting the supporting member such that an inner side of the wall at least partially delimits an inner hollow volume of the supporting member and an outer side of the wall is adapted to be in contact with the ambient environment of the supporting member. The supporting member further comprises a stiffening web frame attached to the wall in order to modify the structural capacity of the supporting member, which stiffening web frame comprises a rib and a flang.

1 ) A marine structure adapted to be located at least partially immersed in water, said marine structure comprising an upper portion adapted to be located above a still water level when said marine structure is located in a body of water, characterized in that said upper portion comprises a wave deflecting member extending out from said marine structure in order to impair wave run-up on said marine structure, wherein said wave deflecting member comprises a plurality of openings, wherein preferably said wave deflecting member comprises a grating, in order to increase the amount of air in the water passing said wave deflecting member. 
     
     
         2 ) The marine structure of  claim 1 , wherein said marine structure is a semi-submersible unit comprising a deck structure and a supporting member, wherein said supporting member extends from said deck structure and is adapted to be at least partially immersed in water. 
     
     
         3 ) The marine structure of  claim 2 , wherein said wave deflecting member is located on said deck structure. 
     
     
         4 ) The marine structure of  claim 2 , wherein said wave deflecting member is located on said supporting member. 
     
     
         5 ) The marine structure of  claim 1 , wherein said wave deflecting member has a tapering extension such that a smallest distance from said upper portion to a portion of said wave deflecting member being located closest to said still water surface is less than a smallest distance from said upper portion to a portion of said deflecting member being located farthest away from said still water surface. 
     
     
         6 ) The marine structure of  claim 1 , wherein said structure comprises a plurality of wave deflecting members. 
     
     
         7 ) The marine structure of  claim 1 , wherein said marine structure is a semi-submersible unit comprising a deck structure and a float, wherein said marine structure further comprises a support column extending between said deck structure and said float. 
     
     
         8 ) The marine structure of  claim 7 , wherein said wave deflecting member is located on said support column.
