PURPOSE:To dissipate waves having longer wave length, by a method wherein a vertical wall, extended from the bottom of a boxform structure moored on a water surface, is located in a direction extending at right angles with dashing waves. CONSTITUTION:A vertical wall 3, extended from the bottom of a boxform structure 2 floating on a sea surface, is disposed in a direction extending right angles with incoming waves W. When the incoming waves W acts on the boxform structure 2, an eddy current 7 is produced behind the vertical wall 3, and a wave dissipating effect is produced by an energy loss. Where the vertical wall 3 forms a porous plate or is formed such that it has slits, in addition to an eddy current action, energy is dissipated while waves pass through the pores or slits, a wave dissipating effect is further increased. |
