Wave attenuator and security barrier system - module

A method for dissipating energy of a wave, the method comprising:

• placing in a location facing an oncoming wave, a module comprising:
• a front surface facing the oncoming wave, the front surface including a pair of sides;
• a rear surface oppositely located with respect to the front surface;
• a top surface;
• a bottom surface;
• and
• the sides connecting the front surface and the rear surface;
• at least three passageways formed in the module,
• each of the at least three passageways having an inlet in the front surface to receive the wave and an outlet in the rear surface to discharge the wave from the module,
• each of the at least three passageways being tapered inwardly in the direction from the inlet to the outlets, such that the wave passing through the at least three passageways is dissipated after being discharged from the outlets.

A system for dissipating energy of a wave, the system comprising:

• a plurality of modules cooperating with each other, each module comprising:
• a front surface facing the oncoming wave, the front surface including a pair of sides;
• a rear surface oppositely located with respect to the front surface;
• a top surface;
• a bottom surface;
• and
• the sides connecting the front surface and the rear surface;
• at least three passageways formed in the module,
• each of the at least three passageways having an inlet in the front surface to receive the wave and an outlet in the rear surface to discharge the wave from the module,
• each of the at least three passageways being tapered inwardly in the direction from the inlet to the outlets, such that the wave passing through the at least three passageways is dissipated after being discharged from the outlets.
