ABSTRACT:
A floating breakwater device for attenuating waves includes an elongated frame extending vertically between an upper end and a lower end. A buoyant member is attached to the frame to support the top end of the frame above the water surface. A barrier is attached to the frame which extends downwardly from the top end of the frame and below the water surface to a position adjacent the bottom end of the frame. The barrier is adapted to intercept and reflect a portion of the kinetic energy of an attacking wave. A first platform and a second platform are attached to the bottom end of the frame on opposite sides. The platforms extend outwardly from the frame to provide stability and resistance to unwanted movement of the breakwater device. A chamber may be removably attached to the bottom end of the frame to be selectively filled with mass such that the chamber provides additional stability and resistance to unwanted movement of the breakwater device and to be selectively filled with a gas such that the chamber is operative to float on the water surface thereby rotating and floating the frame horizontally on the surface of the water to facilitate maintenance of the breakwater device. Inertial masses may be removably attached to the breakwater device to provide additional stability and resistance to unwanted movement.
