Abstract
Abstract Anti-heave protective system including especially designed means adapted to slow down ascending and descending water flows against an obstacle exposed to wave and heave action. These means include material elements such as studs, blade portions or pipe portions, constituting in front of the obstacle, projecting energy dissipating elements over a depth sufficient to penetrate beyond the limit layer of the water mass moving upwards and downwards against the obstacle, and the obstacle comprises a plurality of columns, horizontal drums or the like, arranged in staggered relation to provide a substantially uninterrupted impingement area for the waves.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
Protective system against the heaving action of waves of water comprising a bulky obstacle means having a spreading-out surface and providing a substantially uninterrupted impingement area of substantial extent athwart the wave path and exposed to the impact of successive surges of the heave to induce along said spreading-out surface alternate ascending and descending motions of a mass of water of a thickness greater than a limit layer of water, and means providing a multiplicity of energy dissipating material elements distributed over and projecting in front of said spreading-out surface a distance sufficient to penetrate into said mass of water beyond said limit layer, said elements serving to slow down said ascending and descending water motions and phase-shift the same with respect to the heave, in which the obstacle means is constituted by a plurality of separate obstacle members arranged in staggered relation in a direction perpendicular to the spreading-out surface, and the material elements are borne by the separate obstacle members.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
17 words
Protective system according to claim 1, in which the separate obstacle members comprise a plurality of columns.
Claim 4
Dependent Claim
18 words
Protective system according to claim 1, in which the separate obstacle members comprise a plurality of horizontal drums.
Claim 5
Dependent Claim
18 words
Protective system according to claim 2, in which the separate obstacle members comprise a plurality of horizontal drums.
Claim 6
Dependent Claim
30 words
Protective system according to claim 1, in which said obstacle means are constituted by said plurality of obstacle members arranged in staggered relation to provide said substantially uninterrupted impingement area.
Claim 7
Dependent Claim
36 words
Protective system according to claim 1, in which said obstacle means comprise a number of solid portions, and said separate obstacle members are arranged between said solid portions to provide therewith said substantially uninterrupted impingement area.
