Abstract

Abstract A floating anchored wave barrier is provided comprising a plurality of buoyant members connected by a flexible line. At leat 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 is 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 buoyant members move vertically within the water and out of phase with each other so that water between them is placed under a compressive force thereby reducing the vertical wave velocity component and accelerating the horizontal wave velocity component to form a reflected wave and a transmitted wave. The reflected wave reduces the kinetic energy of other incident waves and the transmitted wave fills in the wave trough of water past the barrier thereby reducing the vertical wave velocity component of the water in the trough.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 185 words
A wave barrier comprising a plurality of buoyant members, at least one of said members comprising a vessel having a closed top, an open 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, each of said disks being of relatively great horizontal extent compared to its vertical dimention, the mass and buoyancy of said members and the distance between said members being such as to provide vertical, out of phase motion of said members to exert a compression force on water between said members to reduce a vertical wave velocity component and increase a horizontal wave velocity component in both a landward and seaward direction without substantial contact of said members.
Claim 2
Dependent Claim 185 words
A wave barrier comprising a plurality of buoyant members, at least one of said members comprising a vessel having a closed top, an open 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, each of said disks being of relatively great horizontal extent compared to its vertical dimention, the mass and buoyancy of said members and the distance between said members being such as to provide vertical, out of phase motion of said members to exert a compression force on water between said members to reduce a vertical wave velocity component and increase a horizontal wave velocity component in both a landward and seaward direction without substantial contact of said members.
Claim 3
Dependent Claim 40 words
The wave barrier of claim 1 wherein the distance between the top of the top buoyant member and the bottom of the lowermost buoyant member is about one-half the wave length of normal waves in which the barrier is positioned.
Claim 4
Dependent Claim 44 words
The wave barrier of claim 1 having two vessels each having at least one annulus attached to the exterior of the vessels and a disk flexibly suspended from a vessel, said disk comprising the vertically lowermost member when the barrier is placed in water.
Claim 5
Dependent Claim 44 words
The wave barrier of claim 2 having two vessels each having at least one annulus attached to the exterior of each vessel and a disk flexibly suspended from a vessel, said disk comprising the vertically lowermost member when the barrier is placed in water.
Claim 6
Dependent Claim 20 words
The wave barrier of claim 1 wherein the lowermost buoyant member is attached to an anchor with a flexible line.
Claim 7
Dependent Claim 58 words
Apparatus for reducing or eliminating the vertical kinetic energy component of water waves on a shore line comprising a plurality of the wave barriers of claim 1 positioned generally parallel to the shore line at different distances from the shore line so that a given portion of an incident water wave contacts at least two of said barriers.
Claim 8
Dependent Claim 58 words
Apparatus for reducing or eliminating the vertical kinetic energy component of water waves on a shore line comprising a plurality of the wave barriers of claim 2 positioned generally parallel to the shore line at different distances from the shore line so that a given portion of an incident water wave contacts at least two of said barriers.
Claim 9
Dependent Claim 21 words
The apparatus of claim 6 wherein said barriers are anchored tO a net located on and secured to the sea bottom.
Claim 10
Dependent Claim 21 words
The apparatus of claim 7 wherein said barriers are anchored to a net located on and secured to the sea bottom.
