11 Claims, 8 Drawing Figures PAIENIEUSEP 3x914 FLOATING OR SUBMERGED MARINE VESSEL FOR STORAGE, SUPPORT OR TRANSPORT The present invention is generally related to marine vessels and, more particularly, to marine structures which may be fabricated from concrete or similar hardenable material and capable of withstanding stresses caused by wave action and the like.
In the past, a variety of concrete type marine vessels have been proposed. However, such constructions, for the most part, have proven unsatisfactory since they did not meet the necessary strength and weight requirements capable of withstanding stresses due to wave action and the like. While a few concrete marine vessels, such as the prestressed types, have proven satisfactory from a structural standpoint, they have been too costly to manufacture and market on a competitive basis with conventional marine vessels.
It is an object of the present invention to provide a novel marine vessel construction which is fabricated from hardenable, moldable materials such as concrete and which is structurally capable of withstanding stresses normally caused by longitudinal wave actions, yet is relatively inexpensive to manufacture.
Another object of the present invention is to provide a unique marine vessel or structure comprising a plurality of intertangentially connected cylindrical walls extending between top and bottom exterior walls to define a plurality of compartments and also provide vertical shear support walls interacting with top and bottom hull slabs thus enhancing the strength of the structure.
It is a further object of the present invention to provide a versatile marine vessel or structure which may be fabricated from concrete or other hardenable, moldable materials by vertical slip form or conventional forming techniques, and which is durable, strong, longlasting and relatively inexpensive to manufacture.
Still another object of the present invention is to pro vide a unique marine structure formed from concrete or similar materials and which may be utilized for stor age or transportation of liquid or dry cargo, such as a barge or tanker, or as a support vessel for heavy equipment or the landing of aircraft.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed,reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout and in which:
FIG. I is a perspective view of the marine structure of the present invention with sections removed.
FIG. 2 is a plan sectional view of the structure of the present invention illustrated in FIG. 1.
FIG. 3 is a sectional view taken along section 33 of FIG. 2.
FIG. 4 is a sectional view takenalong section 4-4 of FIG. 2.
FIG. 5 is a plan sectional view of a second embodiment of the structure of the present invention.
FIG. 6 is a sectional view taken along section 66 of FIG. 5.
FIG. 7 is a sectional view taken along section 77 of FIG. 6.
FIG. 8 is a partial perspective view illustrating vertical slip form equipment and the method which may be utilized for fabricating the marine structure of the present invention.
Referring now, more particularly, to FIG. 1 of the drawings, a typical marine vessel associated with the construction of the present invention is generally indicated by the numeral 10 and includes a plurality-of preciated that the vessel may be utilized for the storage or transportation of dry products such as fertilizer, cement, grain or the like which may be loaded through hatchways such as those at 19.
It should also be noted that the construction of the present invention is not limited to the exact shape and structure illustrated in FIG. 1. In plan, the structure may take the form of a circle, regular or random shape required for the functional purpose. Furthermore, the structures of the present invention may be utilized for both submerged and floating operations. For example, the marine structure may be used for submerged, underwater storage of petroleum products, the structure being located beneath the water in such a manner that it does not obstruct the passage of sea-going vessels and is less affected by the forces of surface wave action.
It will also be appreciated that the construction associated with the present invention may be utilized to provide floating runway structures where land may not be available or where it is desirable to provide a runway facility remote from an urban area. Larger runway areas may be provided by coupling the floating structures together in alignment with each other to utilize the combined top surface areas for runway purposes.
Referring now, more particularly, to FIGS. 2 4, the structure of the present invention may be seen in more detail. Preferably, the structure is fabricated particularly from concrete which may be prestressed or reinforced by conventional means, not illustrated. A plurality of side walls 22 surround the structure and, preferably, are integral with top and bottom walls 14 and 16 which extend substantially the entire length of the structure. The enclosed area between side walls 22 and top and bottom walls 14 and 16 is provided with a plurality of annular walls 24, preferably, but not necessarily, cylindrical inshape, each of which is tangentially connected at 25 and integral with the cylindrical walls immediately adjacent to it. In addition, the outermost cylindrical walls are tangentially integral at 27 with side walls 22, with support webs 29 providing additional strength. The cylindrical walls together define a continuous honeycomb-like network extending throughout the enclosure which provides a plurality of storage compartments, and also greatly enhances the overall strength of the structure.
Each annular wall serves as a vertical shear wall-between top and bottom walls 14 and 16. Furthermore, the interconnection between the adjacent compartments provides a unique structure which is capable of handling large liquid or grain loads which normally exert pressure forces extending outwardly in a radial direction. Since the wall of one compartment is integral with the adjacent compartments, the effect of these radial forces is substantially neutralized. These radial forces are further neutralized by utilizing the generally diamond-shaped compartments at 30, defined between each group of annular walls, for storage purposes. By filling all compartments within the marine structure, the load capacity is approximately the same or greater than that of conventional barge or tanker of the same size, yet, the strength is greatly increased due to the vertical shear wall structure.
It will be appreciated that the annular walls serve as baffles which attenuate undesirable liquid flow within the structure. Since each annular wall defines a separate and independent compartment, different liquids or dry loads may be carried in each compartment while still providing the above mentioned neutralizing effect of the radial pressures exerted upon the walls of the adjacent compartments.
Referring now, more particularly, to FIGS. 57, a second embodiment of the marine structure of the present invention is illustrated and is generally indicated by the numeral 34 and includes a plurality of side walls 36, similar to those illustrated in FIG. 2. It should be noted, that the second embodiment, as well as the first embodiment, may take several forms, such as rectangles, circles, squares, or the like, Basically the second embodiment utilizes the same concepts as the first, however, a substantial cost savings is realized by interconnecting the annular, or cylindrical, walls indicated at 38 with radial walls 40 which lie along a line between the axes of the adjacent cylinders and which extends between the top and bottom walls 42 and 44, respectively. Thus, the radial load forces exerted outwardly upon each cylindrical wall is transmitted to the adjacent cylindrical compartment by way of the radial walls, rather than a direct intertangential connection as utilized with the first embodiment. By utilizing the radial walls of the second embodiment, a significant reduction in the volume of concrete per unit of volume of storage space may be realized. This is readily apparent from the volume equation for each embodiment. For example, the volume of concrete for a single cylin drical wall of the first embodiment may be expressed as follows:
Where R,, mean radius, /1 height, and I wall thickness. The volume of concrete required to produce substantially the same storage area with the structure of the second embodiment may be expressed as follows:
Where r,,, mean radius, r wall thickness, I1 height of the cylinder, and 1 radial wall length. Since the cylinder wall volume increases by a factor of 1r as the radius increases, it is apparent that the total wall volume is less when the radial walls are utilized and a significant cost savings may be realized.
It will be appreciated that the vertical shear walls of both the first and second embodiments resist shear in the longitudinal and transverse directions. The top and bottom hull walls, in turn, act as flanges which resist bending moment in both the longitudinal and transverse directions.
Referring to FIG. 8, the preferred method of fabrication is illustrated. It has been found that the structure of the present invention may be most economically produced by the method of vertical slip forming a concrete structure. This is done by providing vertically movable forms including an outer form 26 to shape exterior walls 22 and a plurality of cylindrical forms 28 which are jacked or otherwise moved upwardly in unison as the lower layers of concrete reach a hardened condition. The fonns are continuously filled with concrete supplied by way of a crane assembly 32.
Several techniques and methods of vertical slip forming and the drying procedures related thereto are well known and, of themselves, do not form a part of the present invention. It should be noted that, if desired, the structure of the present invention may be fabricated by the use of more conventional techniques and materials such as structural steel. It will be appreciated, however, that due to the unique shear wall construction associated with the present invention, the structure may be economically fabricated by vertical slip techniques, while conventional marine structures of comparable strength had to be fabricated from steel or similar materials requiring high material and labor costsv Minor changes in the relative positions or number of vertical shear walls or the hull configuration are deemed to fall within the scope of the present invention.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
