Abstract
Abstract A flotation structure in the shape of an elongate bottle is cast in concrete as well as are sets of prestressed rods disposed at opposite ends of the structure. A plurality of such structures is joined together in sets by coupling devices provided at opposite ends of the prestressed rods to yield a highly stable floating platform since the center of buoyancy is well below surface wave turbulence. The necks of the bottle-shaped flotation structures have reduced cross-sectional area to minimize the possibility of an adverse reaction to surface wave action, e.g., rolling or heaving reactions within each flotation structure enables a selective shifting of ballasts to facilitate launching and alignment when several structures are joined together without requiring any elaborate support facilities. Sets of flotation structures are hinged together to form runways or include spaces vacant of flotation structures to form dry docks or reduced capacity platforms.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
A flotation structure for diminishing the effects of surface wave action comprising: an elongate bottle-shaped chamber cast of concrete and formed to include, a first portion having a cross-sectional area disposed and sized for defining a center of buoyancy below said wave action and, a second portion defining the neck of said bottle-shaped chamber integrally extending therefrom through and above the area of said wave action having a fractional said cross-sectional area; lower connecting means carried adjacent said first portion including a plurality of prestressed members mounting coupling means attached on their opposite ends; and upper connecting means carried adjacent said second portion including a plurality of prestressed members mounting coupling means attached on their opposite ends, said lower and said upper connecting means also cast in said concrete thereby forming an integral said flotation structure.
Claim 2
Dependent Claim
136 words
A flotation structure for diminishing the effects of surface wave action comprising: an elongate bottle-shaped chamber cast of concrete and formed to include, a first portion having a cross-sectional area disposed and sized for defining a center of buoyancy below said wave action and, a second portion defining the neck of said bottle-shaped chamber integrally extending therefrom through and above the area of said wave action having a fractional said cross-sectional area; lower connecting means carried adjacent said first portion including a plurality of prestressed members mounting coupling means attached on their opposite ends; and upper connecting means carried adjacent said second portion including a plurality of prestressed members mounting coupling means attached on their opposite ends, said lower and said upper connecting means also cast in said concrete thereby forming an integral said flotation structure.
Claim 3
Dependent Claim
43 words
A structure according to claim 1 further including: a plurality of flotation structures each having a coupling means carried on its lower connecting means and on its upper connecting means oriented for interconnection to adjacent elongate bottle-shaped chambers to form a stable platform.
Claim 4
Dependent Claim
19 words
A structure according to claim 1 in which the neck-shaped portion is shaped with a convex-conically flaring outer portion.
Claim 5
Dependent Claim
42 words
A structure according to claim 3 in which each said lower and said upper connecting means is a square-shaped stress collar provided with a center area configured to encompass a lower portion of said bottle-shaped chamber and said flaring outer portion, respectively.
Claim 6
Dependent Claim
34 words
A structure according to claim 4 in which said prestressed members are four sets of prestressed reinforcing rods each set cast within a separate side of said stress collar for maintaining same in compression.
Claim 7
Dependent Claim
23 words

Claim 11
Dependent Claim
30 words
A structure according to claim 7 in which spaces are provided vacant of said elongate chambers in said stable platform to form a floating drydock and reduced lift capacity platform.
