Auxiliary float of floating structure and method for remodeling floating structure

An auxiliary float of a floating structure, wherein the floating structure includes a plurality of lower hulls forming a float, an upper hull constituting a deck, a plurality of columns that couples said lower hulls and said upper hull to each other, and a brace coupled to an assembly of said lower hulls, said upper hull and said columns, the auxiliary float comprising:

• floating bodies, configured to give buoyancy to the floating structure and to reduce a draft of the floating structure, coupled to a lower portion of said lower hulls;
• and
• a plurality of coupling members that couple the floating bodies to each other,
• wherein said coupling members include a main coupling member that couples said floating bodies to each other and a sub-coupling member that is directly coupled to the main coupling member and said floating bodies.

A method for remodeling a floating structure, wherein, for a floating structure having a plurality of lower hulls forming a float, an upper hull constituting a deck, a plurality of columns that couples said lower hulls and said upper hull to each other, and a brace coupled to an assembly of said lower hulls, said upper hull and said columns, the method comprising the steps of:

• providing an auxiliary float including floating bodies to be coupled to a lower portion of said lower hulls and a plurality of coupling members that couple the floating bodies to each other,
• mounting said floating structure on the auxiliary float,
• connecting said lower portion of said lower hulls and said floating bodies to each other to thereby reinforce and provide increased strength for the floating structure, and
• forming a communicating hole that connects the interior of said lower hull and the inner space of said floating body in the bottom surface of said lower hull.
