Abstract
Abstract Floating installation having a platform, at least one element providing for the buoyancy of the installation and apparatus connecting the platform to the buoyant element. The element is constituted by at least one flexible, tight and deformable bag housing a determined mass of gas, which is sufficient for maintaining, during its operation, the platform and the connecting apparatus above the maximum level reached by the crest of the waves, thus reducing considerably the action of swell on the installation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A floating installation comprising a platform, buoyant means for supporting the platform, and means connecting said platform to said buoyant means, the buoyant means including at least one flexible, tight and deformable closed bag housing a determined mass of gas, which is sufficient for maintaining during its operation said platform and said connecting means above the maximum level reached by the crest of the waves, the buoyant means being responsive to the action of a swell for assuming in a vertical plane the profile of a substantially sinusoidal curve for considerably reducing the action of the swell on the installation, the connecting means including first resilient means for enabling the buoyant means to assume in a vertical plane the profile of a substantially sinusoidal curve in response to the action of the swell, the first resilient means being located between the platform and the buoyant means.
Claim 2
Dependent Claim
146 words
A floating installation comprising a platform, buoyant means for supporting the platform, and means connecting said platform to said buoyant means, the buoyant means including at least one flexible, tight and deformable closed bag housing a determined mass of gas, which is sufficient for maintaining during its operation said platform and said connecting means above the maximum level reached by the crest of the waves, the buoyant means being responsive to the action of a swell for assuming in a vertical plane the profile of a substantially sinusoidal curve for considerably reducing the action of the swell on the installation, the connecting means including first resilient means for enabling the buoyant means to assume in a vertical plane the profile of a substantially sinusoidal curve in response to the action of the swell, the first resilient means being located between the platform and the buoyant means.
Claim 3
Dependent Claim
12 words
A floating installation according to claim 1, wherein said gas is air.
Claim 4
Dependent Claim
36 words
A floating installation according to claim 1, wherein the length of said buoyant means in the direction of propagation of the swell has a value at least equal to one half of the wave-length of swell.
Claim 5
Dependent Claim
16 words
A floating installation according to claim 1, wherein said buoyant means has a substantially cylindrical shape.
Claim 6
Dependent Claim
16 words
A floating installation according to claim 1, wherein said buoyant means has a substantially annular shape.
Claim 7
Dependent Claim
14 words
A floating installation according to claim 1, wherein said resilient means are damping means.
Claim 8
Dependent Claim
33 words
A floating installation according to claim 1, wherein the buoyant means include a plurality of closed bags, and further including second resilient means disposed between adjacent bags for interconnecting the plurality of bags.
