Abstract:A new kind of perforated free surface semicircular naval structure is
   presented.The hydrodynamic characteristics of naval structure are
   investigated in regular and irregular wave conditions under the
   different water depths,submergence depths,wave heights and wave
   periods.The performance of the naval structure was evaluated in the form
   of transmission coefficient(C_t),reflection coefficient(C_r) and energy
   dissipation coefficient(C_l).It is found that the wave attenuation
   ability of the naval structure model improves with the increase of
   submerged depth and relative plate width.The naval structure performs
   better as an energy dissipater than as a wave reflector,and is suitable
   for offshore infrastructure construction.
