Abstract
Abstract A floating anchored wave barrier is provided comprising a plurality of members connected by a flexible line or rigid connecting means. At least one of the members is an inverted vessel having an annulus attached to the periphery of the vessel. The buoyancy and mass of the members are such that when the barrier is placed in water, the top vessel is positioned at or near the water surface and each vessel if partially filled with air. The remaining members can be a vessel having an annulus attached thereto or a disk having a relatively great horizontal extent compared to its thickness. The remaining members are submerged but near the water surface so that they are located within the top portion of the wave where the major portion of the wave kinetic energy is encountered. The top vessel is caused to pitch by the energy of incoming waves and is anchored at or near the axis of pitch to form a wave pattern emanating from the top vessel which impinges upon incoming waves thereby reducing their kinetic energy prior to contact with the members.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
236 words
A wave barrier having a top member and a second member attached to said top member, said top member having at least one annulus extending from a body portion of said top member, said second member being positioned at a deeper water depth than said top member when said barrier is anchored in water, said top member being located at or near the water surface, said second member being submerged near the water surface, the masses and specific gravity of the top member, annulus and second member being controlled so that the top member and second member are maintained generally along a common vertical axis with respect to each other when placed in water, said barrier being anchored to the sea bottom by a flexible line extending from an anchor to a point at or near to an axis of pitch of said top member in order to maximize oscillation of said top member about said axis of pitch and so that said annulus causes formation of wave fronts to contact incoming waves to reduce a vertical wave velocity component of the incoming waves and without substantial contact of said members, said axis of pitch being determined under the average expected wave condition in the water, and said axis of pitch being oriented in a direction generally perpendicular to the direction of movement of incoming waves toward the shore when said barrier is anchored in water.
Claim 2
Dependent Claim
236 words
A wave barrier having a top member and a second member attached to said top member, said top member having at least one annulus extending from a body portion of said top member, said second member being positioned at a deeper water depth than said top member when said barrier is anchored in water, said top member being located at or near the water surface, said second member being submerged near the water surface, the masses and specific gravity of the top member, annulus and second member being controlled so that the top member and second member are maintained generally along a common vertical axis with respect to each other when placed in water, said barrier being anchored to the sea bottom by a flexible line extending from an anchor to a point at or near to an axis of pitch of said top member in order to maximize oscillation of said top member about said axis of pitch and so that said annulus causes formation of wave fronts to contact incoming waves to reduce a vertical wave velocity component of the incoming waves and without substantial contact of said members, said axis of pitch being determined under the average expected wave condition in the water, and said axis of pitch being oriented in a direction generally perpendicular to the direction of movement of incoming waves toward the shore when said barrier is anchored in water.
Claim 3
Dependent Claim
134 words
The wave barrier of claim 1 comprising a plurality of members, at least one of said members comprising a vessel having a closed top, a bottom and at least one annulus secured to the exterior of the vessel, the remainder of said members being a disk or one of said vessels having at least one annulus attached to the exterior of the vessel, said members being flexibly suspended to each other and, when anchored in water, having a configuration such that the members are located at different vertical levels along a common vertical axis and each vessel has its bottom at a lower water level than its top and wherein said top member is one of said vessels, and each of said disks being of relatively great horizontal extent compared to its vertical dimension.
Claim 4
Dependent Claim
