Description

LICUATED NATURAL GAS STORAGE TANK BACKGROUND OF THE INVENTION The present invention relates to liquefied gas storage tanks and in one aspect refers to tanks specially adapted to store liquefied gases at cryogenic temperatures at pressures close to atmospheric (e.g. liquefied natural gas ("LNG")). In the following specification several terms are defined. For convenience, a Glossary of terms is provided herein, immediately preceding the claims. Liquefied natural gas (LNG) is typically stored at cryogenic temperatures of approximately -162 ° C (-260 ° F) and at substantially atmospheric pressures. As used herein, the term "cryogenic temperature" includes any temperature of about -40 ° C (-40 ° F) and below. Typically, the LNG is stored in tanks or double-walled containers. The inner tank provides the primary containment for the LNG, while the outer tank contains the insulation in place and protects the inner tank and the insulation from adverse effects of the environment. Sometimes, the outer tank is also designed to provide secondary containment of the LNG in case the inner tank malfunctions. Typical tank sizes at LNG import or export terminals range from approximately 80,000 to approximately 160,000 meters3 (0.5 to 1.0 million barrels) although tanks as large as 200,000 square meters (1.2 million barrels) have been built or are under construction. barrels). For a large volume of LNG storage, two different types of tank construction are widely used. The first of these is an autonomous, cylindrical, flat bottom tank that typically uses a 9% nickel steel for the inner tank and carbon steel, 9% nickel steel, or reinforced / prestressed concrete for the outer tank. The second type is a membrane tank where a thin metal membrane (eg, 1.2 mm thick) is installed inside the cylindrical concrete structure which, in turn, is constructed either below or above the level of the Earth. Typically, an insulating layer is interposed between the metal membrane, for example, stainless steel or a product with the trade name Invar, and the cylindrical walls that carry the concrete load and the flat floor. Although they are structurally effective, circular cylindrical tanks in designs in the state of practice are time consuming and difficult to construct. Autonomous 9% nickel steel tanks, in the popular design where the secondary secondary container is able to contain both liquid and gas vapor, although at near atmospheric pressure it takes about thirty-six months to build. Typically, membrane tanks take as much or more time to build. In many projects, this causes an unwanted increase in the construction costs and extension of the construction program. Recently, radical changes have been proposed in the construction of LNG terminals, especially in import terminals. One such proposal involves the construction of the terminal at a short distance offshore where the LNG is unloaded from a transport vessel, and stored for recovery and regasification for sale or use as necessary. One of these proposed terminals has LNG storage tanks and regasification equipment installed in, what is popularly known as, Gravity Platforms (GBS), a barge-like structure, of substantially rectangular shape similar to certain concrete structures now installed in the seabed and used as platforms to produce oil- in the Gulf of Mexico. Unfortunately, neither the cylindrical tanks nor the membrane tanks are considered particularly attractive for use in the storage of LNG in GBS terminals. Typically, cylindrical tanks do not store enough LNG to economically justify the amount of space these tanks occupy in a GBS and are difficult and expensive to build in a GBS. In addition, the size of these tanks should typically be limited (for example, no larger than approximately 50,000 meters3 (approximately 300,000 barrels)) so that GBS structures can be manufactured economically with easy-to-manufacture manufacturing facilities. This requires multiple storage units to meet specific storage requirements, which are not typically desirable from the cost and other operational considerations. A membrane type tank system can be built into a GBS to provide a relatively large storage volume. However, a membrane-type tank requires a sequential construction program in which the external concrete structure has to be completely constructed before the insulator and the membrane can be installed within a cavity within the outer structure. This usually requires a long construction period, which tends to add substantially to the project costs. Accordingly, a tank system is needed, both for conventional ground terminals and for offshore LNG storage, in which the tank system alleviates the previously discussed disadvantages of self-contained cylindrical tanks and membrane type tanks.

In published designs of rectangular tanks (see, for example, Farrell et al, U.S. Patent Nos. 2,982,441 and 3,062,402, and Abe, et al, U.S. Patent No. 5,375,547), the plates that constitute the walls of the tank containing the fluids they are also the greatest source of tank resistance and stability against all applied loads including static and, when used on land in a conventional LNG import or export terminal or a GBS terminal, against dynamic earthquake-induced loads. For these tanks, a higher plate thickness may be required even when the volume of liquid contained is relatively small, for example, 5,000 meters3 (30,000 barrels). For example, Farrell et al, North American 2,982,441 provides an example of a much smaller tank, ie 45,000 ft3 (1275 m3), which has a wall thickness of approximately 1/2 inch (see column 5, lines 41-45). ). Straps may be provided to connect the opposite walls of the tank for the purpose of reducing deviations from the wall and / or straps may be used to reinforce the corners in the adjacent walls. Alternatively, bulkheads and diaphragms can be provided inside the tank to provide additional strength. When tie rods and / or bulkheads are used, such tanks to moderate sizes, for example, 10,000 to 20,000 meters3 (60,000 to 120,000 barrels), may be useful in certain applications. For the traditional use of rectangular tanks, the limitation in size of these tanks is not a particularly severe restriction. For example, both the tanks of Farrell, et al, and Abe, et al, were invented for use in the transport of liquefied gases for offshore vessels. Ships and other floating vessels used in the transport of liquefied gases are typically limited to contain tanks of sizes up to approximately 20,000 meters3. Large tanks on the scale of 100,000 to 200,000 meters3 (approximately 600,000 to 1.2 million barrels), constructed according to the teachings of Farrell et al and Abe, et al, may require diaphragms and solid interior bulkheads and would be very expensive to build. Typically, any tank of the type taught by Farrell et al, and Abe, et al, that is, in which the strength and stability of the tank are provided by the outer walls of the tank containing liquid or a combination of the diaphragms inside the tank. tank and the outer walls of the tank that contains liquid, will be a little expensive, and generally too expensive to be considered economically attractive. There are many sources of gas and other fluids in the world that can be economically developed and delivered to consumers if an economical storage tank is available. The bulkheads and diaphragms inside a tank built according to the teachings of Farrell, et al, and Abe, et al, could also subdivide the interior of the tank into multiple small cells. When used on boats or similar floating bodies, small liquid storage cells are an advantage because they do not allow the development of large magnitudes of dynamic forces due to the dynamic movement induced by ocean waves of the ship. Dynamic movements and forces due to earthquakes in tanks built on land or on the seabed are, however, different in nature and large tank structures that are not subdivided into a multitude of cells typically turn out to be better when subjected to these movements and forces. Accordingly, there is a need for a storage tank for LNG and other fluids that satisfies the primary functions of fluid storage and that provides resistance and stability against loads caused by fluids and the environment, including earthquakes., although they are built of relatively thin metal plates and in a relatively short construction program. Such a tank, preferably, will be capable of storing 100,000 meters3 (approximately 600,000 barrels) and large volumes of fluids and will be much easier to construct than current tank designs. The present invention provides tanks of substantially rectangular shape for storing fluids, such as liquefied gas, these tanks are specially adapted for use on land or in combination with offshore structures supported by the bottom such as gravity structures (GBS). Methods to build such tanks are also provided. A fluid storage tank according to an embodiment of this invention comprises (I) a structure of the armor frame of substantially rectangular, internal shape, this structure of the internal armor frame comprises: (i) a first plurality of structures of the armature located transversally and longitudinally separated from each other in a first plurality of parallel vertical planes along the length direction of the structure of the internal armor frame; and (ii) a second plurality of structures of the armature located longitudinally and spaced transversely to each other in a second plurality of parallel vertical planes along the width direction of the structure of the internal armor frame; the first plurality of reinforcement structures and the second plurality of structures of the reinforcement interconnected at the points of intersection and each of the first and second plurality of reinforcement structures comprises: (a) a plurality of vertical extended supports and supports horizontal extensions, connected at their respective ends to form a framework of structural members, and (b) a plurality of additional support members secured within and between the vertical and horizontal extended supports connected to thereby form each reinforcement structure; (II) a grid of reinforcements and beams arranged in a substantially orthogonal pattern, interconnected and attached to the outer ends of the structure of the internal reinforcement frame so that when attached to the vertical sides of the periphery of the reinforcement, the reinforcements and stringers are in substantially vertical and horizontal directions respectively, or in substantially horizontal and vertical directions respectively, and (III) a plate cover attached to the periphery of the grid of reinforcements and stringers; all in such a way that the tank is capable of storing fluids at a substantially atmospheric pressure and the plate cover is adapted to contain the fluids and transfer induced local loads in the plate cover by contact with the contained fluids to the grid of reinforcements and stringers, which in turn is adapted to transfer the local loads to the structure of the internal reinforcement frame. As used herein, a plate or plate cover is intended to include (i) a substantially smooth and substantially flat body of substantially uniform thickness or (ii) two or more substantially smooth and substantially flat bodies joined together by any method suitable joining, such as welding, each substantially smooth and substantially flat body having a substantially uniform thickness. The plate cover, the grid of reinforcements and spars, and the structure of the internal reinforcement frame can be constructed of any suitable material that is appropriately ductile and has acceptable fracture characteristics at cryogenic temperatures (for example, a metal plate such as nickel steel). to 9%, aluminum, aluminum alloys, etc.), as can be determined by one skilled in the art. An alternative embodiment of the invention includes a substantially rectangular fluid storage tank having a length, width, height, first and second ends, first and second sides, upper part and lower part. The fluid storage tank includes an internal frame structure and a plate cover that surrounds the structure of the internal frame. The structure of the internal frame includes a plurality of first full-beam girder ring frames having internal sides disposed towards the interior of the fluid storage tank and external sides. The first full-soul beam ring frames are located extending along the width and height of the fluid storage tank and separated along the length of the fluid storage tank. The structure of the internal frame further includes a first plurality of reinforcement structures with each of the first structures of the reinforcement (i) corresponding to one of the first full-beam girder ring frames and (ii) are arranged in the plane of and within one of the first full-beam girder ring frames holding, thus, the internal sides of the first full-girder beam ring frame. The structure of the inner frame can further include a plurality of second full-beam beam frames having internal sides disposed towards the interior of the fluid storage tank and the outer sides. The second ring frames can be located extending along the height and length of the fluid storage tank and spaced along the width of the fluid storage tank. The structure of the internal frame can be composed so that the intersection of the full-beam girder ring frames forms a plurality of adhesion points forming, thus, a structure of the integrated internal frame. The fluid storage tank also includes a plate cover that surrounds the structure of the internal frame. The plate cover has an inner side and an outer side, where the inner side of the plate cover is disposed towards the outer sides of the first and second ring frame. An alternative embodiment of the invention includes a method for constructing a fluid storage tank. The method includes (A) providing a plurality of plates, a plurality of reinforcements and spars, and a plurality of portions of the full soul beam ring frame.; (B) forming a cover plate from one or more of the plurality of plates; (C) joining a portion of the plurality of reinforcements and stringers to a first side of the plate cover; and (D) joining a portion of the plurality of portions of the filled core girder beam frame to the first side of a first plate cover thereby forming a panel member. An alternative embodiment of the invention includes a method for constructing a fluid storage tank. The method includes (A) providing a plurality of panel elements, a plurality of tank modules, or a combination thereof. The plurality of panel elements and the plurality of tank modules include plate covers having a plurality of reinforcements, stringers and portions of the full-beam beam frame, attached to the first side of the plate cover. The method further includes (B) assembling the plurality of panel elements, the plurality of tank modules, or combinations thereof to form a fluid storage tank thereby forming a plurality of full soul beam ring frames. within the storage tank from the plurality of portions of filled soul beam ring frames. A tank according to this invention can be a structure of substantially rectangular shape that can be built on land and / or placed in a space within a GBS of steel or concrete and that is capable of storing large volumes (e.g., 100,000 m 3 and greater) of LNG at cryogenic temperatures and pressures close to atmospheric. Due to the open nature of the framework and / or full soul beam ring frames inside the tank, it is expected that this tank containing LNG will have superior performance in areas where seismic activity is found (eg, earthquakes). and where such activity may cause a liquid spill and associated dynamic loads within the tank. The advantages of the structural arrangement of the present invention are clear. The plate cover is designed for fluid containment and to withstand local pressure loads, for example, caused by fluid. The plate cover transmits the local pressure loads to the structural grid of reinforcements and stringers in some embodiments of the invention, which in turn transfers the loads to the frame structure of the internal reinforcement and / or full-beam beam frames. in some embodiments of the invention. The structure of the internal reinforcement frame and / or the structure of the soul girder ring frame filled in some embodiments of the invention finally support all the loads and discard them towards the base of the tank; and the structure of the internal reinforcement frame and / or structure of the filled soul beam frame, in some embodiments of the invention, can be designed to be strong enough to meet any such load bearing requirements. Preferably, the plate cover is designed only for fluid containment and to withstand local pressure loads. The separation of the two functions of a tank structure, that is, the liquid containment function performed by the plate cover, and the stability and strength of the overall tank provided by the internal armor structure and the structure of the ring frame of full web beam and structural grid of reinforcements and stringers in some embodiments of the invention allow to use thin metal plates, for example, up to 13 mm (0.52 inches) for the plate cover. Although thicker plates can also be used, the ability to use thin plates is an advantage of this invention. This invention is especially advantageous when a tank of substantially large rectangular shape, for example, about 160,000 meters3 (1.0 million barrels) is constructed in accordance with this invention using one or more metal plates having approximately 6 to 13 mm (0.24 to 0.52). inches) thick to build the plate cover. In some applications, the plate cover is preferably approximately 10 mm (0.38 inches) thick. Many different arrangements of beams, columns and arms can be designed to achieve the desired strength and stiffness of a frame structure as illustrated by the use of armors on bridges and other civil structures. For a tank of the present invention, the construction of the framework structure of the reinforcement in the longitudinal (long) and transverse (wide) directions when present is different. The reinforcements in the two different directions in one embodiment of the invention are designed to provide, at a minimum, the strength and stiffness required for the expected overall dynamic performance when subjected to specified seismic activity and other specified load bearing requirements. For example, there is usually a need to hold the roof structure of the tank against internal vapor pressure loads and to support the entire structure of the tank against the loads due to the inevitable unevenness of the tank floor. By using a frame structure of the inner frame and / or the structure of the filled soul beam frame frame in an embodiment of the invention to provide the primary support for the tank, the interior of the tank can be effectively contiguous along the length of the tank. tank without any obstruction provided by any bulkhead or similar. This allows the relatively long interior of the tank of this invention to avoid resonance conditions during the spill under the substantially different dynamic load caused by seismic activity as opposed to the load occurring during the movement of an offshore vessel. Contrary to the published designs of rectangular liquid storage tanks that do not teach about the strength and rigidity of the tank walls in the vertical direction, the structural arrangement of the present invention allows the use of structural elements such as reinforcements and stringers both in the horizontal direction as vertical to achieve a good structural performance in some embodiments of the invention. Similarly, although published designs require the installation of bulkheads and diaphragms to achieve the tank resistance required with such bulkheads and diaphragms, greater waves of liquid spillage occur during an earthquake and thus cause large forces in the structure of the tank. diaphragm and walls the tank, the open frame of the reinforcements in the tanks according to this invention minimize the dynamic loads due to liquid spillage at earthquake prone sites.

FIGS. 11-13 describe embodiments of the full-beam beam frame / internal frame of the frame structure of an embodiment of the invention. FIGURE 14 discloses a soul beam ring frame filled with one embodiment of the invention. FIGURE 15 discloses a mode of full soul beam ring frame embodiment composed of panel elements. FIGURE 16 shows how the panel elements described in FIGURE 15 can be stacked for shipping. Although the invention will be described in connection with the preferred embodiments, it should be understood that the invention is not limited thereto. On the contrary, the invention is intended to cover all alternatives, modifications, and equivalents that may be included within the spirit and scope of the present disclosure, as defined in the appended claims. A storage tank of substantially rectangular shape of a preferred embodiment of the present invention is designed to provide the possibility of varying the capacity of the tank, in different stages, without a substantial redesign of the tank. Only for construction purposes, this is achieved considering that the tank comprises a number of similar structural modules. For example, a 100,000-meter3 tank can be considered to comprise four substantially equal structural modules obtained by cutting a long tank in three imaginary vertical planes suitably spaced along the length direction so that each section is conceptually capable of containing approximately 25,000 meters3 of liquid. Such a tank is comprised of two substantially identical end sections and two substantially identical middle sections. When removing or adding middle sections during the construction of the tank, tanks of the same cross section can be obtained, in different stages, that is, same height and width, but variable length and, thus, variable capacity. A tank having two end sections, but not half sections, can also be constructed in accordance with this invention. The two end sections are structurally similar, preferably identical, and may comprise one or more vertical transverse trusses and full-core girder ring frames corresponding in some embodiments of the invention and vertical longitudinal truss parts and portions of the truss armors. Soul beam ring filled in some embodiments of the invention that when connected to similar parts of the contiguous middle sections (or end sections) during the construction process will provide continuous vertical longitudinal reinforcements and full soul girder ring frames in some embodiments of the invention and a monolithic tank structure. All the middle sections, if any, must have a similar construction, preferably substantially the same, and each is composed of one or more transverse frames and the same number of full-beam beam frames in some embodiments of the invention and portions of the longitudinal and / or corresponding portions of the filled soul girder ring frames in some embodiments of the invention in a similar manner as for the end sections. For both the end sections and the middle sections, a structural grid (including reinforcements and stringers) and plates are attached to those extremities of the internal frame that will eventually form the outer surface, including the plate cover, of the finished tank, and preferably , only in such extremities of the internal frame. FIGS. 1A-1D describe the basic structure of a storage tank embodiment according to this invention. Referring to FIGURE IA, a tank 10 of substantially rectangular shape is 100 meters (328 feet) long 12 by 40 meters (131 feet) wide 14 by 25 meters (82 feet) high 16. Basically, tank 10 is composed of a structure 18 of the frame of the internal reinforcement, a grid of reinforcements 27 and beams 28 (shown in FIGS. 1C and ID) attached to the frame structure 18 of the frame, and a thin plate cover 17 attached to the grid. of reinforcements 27 and stringers 28.

The thin plate cover 17, the grid of reinforcements 27 and stringers 28, and the frame structure 18 of the inner reinforcement can be constructed of any suitable material that is ductile and has acceptable fracture characteristics at cryogenic temperatures (eg, a plate metal such as 9% nickel steel, aluminum, aluminum alloys, etc.). In a preferred embodiment, the thin plate cover 17 is constructed of steel having a thickness of about 10 mm (0.38 inches), more preferably from about 6 mm (0.25 inches) to about 10 mm (0.38 inches). The thin plate cover 17 when assembled (i) provides a physical barrier adapted to contain a fluid, such as LNG, within the tank 10 and (ii) supports local pressures and charges caused by contact with the contained fluids, and transmits such pressures and local loads to the structural grid composed of reinforcements 27 and beams 28 (See FIGURES 1C and ID), which, in turn, transmit these loads to the structure 18 of the reinforcement frame. The structure 18 of the armor frame finally supports the aggregation of local loads, including liquid spill charges induced by earthquakes caused by earthquakes, transmitted by a thin plate cover 17 and the structural grid from the periphery of the tank 10 and disposes these loads to the base of tank 10.

More specifically, the storage tank 10 is a substantially rectangular, self-stable tank that is capable of storing large quantities (eg, 100,000 meters3 (approximately 600,000 barrels)) of liquefied natural gas (LNG). Although different construction techniques may be used, FIGURES IB-ID illustrate a preferred method for assembling a tank according to one embodiment of this invention, such as tank 10. For manufacturing and construction purposes, tank 10 with adjacent interior space it can be considered as cut into a plurality of sections, eg, ten sections, comprising two substantially identical end parts 10B (FIGURE ID), and a plurality, eg, eight, sections 10A (FIGURES IB and 1C) substantially identical means . These sections 10A and 10B can be transported by marine vessels or barges to the construction and assembly site in a monolithic tank unit. This method of construction provides a means to achieve a variable tank size 10 to meet varying storage requirements without the need to redesign tank 10. This is achieved by maintaining the design of the extreme 10B sections and the 10A half sections substantially equal , but varying the number of 10A half sections that are inserted between the two extreme sections 10B. Although technically possible, this embodiment of the invention may present challenges in certain circumstances. For example, for large tanks constructed of a thin steel plate, the handling of the structural sections that eventually comprise the tank during transportation and assembly of the sections in a monolithic tank would require great care to avoid damaging any of the sections. In another embodiment of this invention, a modified tank design configuration is provided which results in easier manufacturing methods to build a tank of this invention. FIGURE 2 describes the configuration of the structure of the tank 50. An end panel is taken out of the tank 50 (ie, not shown in FIGURE 2) to reveal part of the internal structure 52 of the tank 50. In detail somewhat larger , a 50 rectangular tank with a capacity of 100,000 meters3 has 90 meters (approximately 295 feet) of length 51, 40 meters (approximately 131 feet) width 53 and 30 meters (approximately 99 feet) high 55. When fully assembled and installed at the service location, the tank 50 comprises an internal structure 52 composed of an internally reinforced frame structure of substantially rectangular shape, a grid of reinforcements and stringers (not shown in FIGURE 2) attached to the structure of the frame of reinforcement, and a cover 54 of thin plate attached in the form of a seal to the structural grid of reinforcements and stringers; and the tank 50 fully assembled provides a contiguous and unloaded space for the storage of liquefied gas in the interior. FIGURES 3 and 4 show sectional views of tank 50 (of FIGURE 2) cut respectively by vertical planes along (longitudinal) and wide (transverse). FIGURE 3 shows members 60a and 60b of the typical frame structure and the lengthwise (longitudinal) arrangement of the tank 50. FIGURE 4 shows members 70a and 70b of the typical frame structure and the arrangement in direction of the width (transverse) of the tank 50. For a fully assembled tank, the design illustrated in FIGURES 2-4 separates the required functions from the fluid containment tank and the provision of strength and stability by providing separate and distinct structural systems for each one, that is to say, a thin plate cover for the containment of fluid and a structure of the frame of three-dimensional reinforcement and a grid of reinforcements and beams for a resistance and overall stability, although an integrated manufacture of the two is proposed systems to achieve economy in the cost of installing the tank. Therefore, for manufacturing purposes, the tank 50 can be considered as divided into four sections, as shown in Figure 2, which comprises two substantially identical end sections 56 and two substantially identical half sections 57. Each of the end and middle sections of the tank can further be subdivided into panels (see, for example, panels 83, 84 and 85 of FIGURE 5A). Each panel may comprise the plate cover, reinforcements and / or spars, and structural members or trusses of structural members for use in the construction of the internal reinforcement structure. To facilitate manufacturing, the internal structure 52 is divided into two parts, a part that can be attached to the panels while they are being manufactured in the line of panels of a shipyard and a part that is installed inside the tank 50 while the panels are assembled in a finished tank. The solid lines in FIGURES 3 and 4 show armor members 60a and 70a that are attached to the panels while they are manufactured. The structures of the armor specifically attached to the panels to facilitate the manufacture of panels can be in any form of reinforcement. For example, a pure Warren armor, a pure Pratt armor, a plated Pratt armor, or other armor configuration known in the art. The dotted lines in Figures 3 and 4 illustrate reinforcement members 60b and 70b that are installed while the panels are assembled in the structure of a finished tank.

In an alternative embodiment, a substantially rectangular fluid storage tank having an internal frame structure is provided. The structure of the internal frame may include a plurality of full-beam girder ring frames having internal sides disposed towards the interior of the fluid storage tank while the inner sides of the full-soul girder ring frames can be supported by the outer edges or limbs of a plurality of structures of the armor. In this way, the structure of the internal frame can include a plurality of reinforcement structures with an armature structure corresponding to each full-beam beam frame. The structure of the frame can be arranged in the plane of and inside the full-beam beam frame frame thus holding the first full-beam beam frame. In one configuration, the reinforcement structure may include a plurality of vertical extended supports and horizontal extended supports, connected to form a framework of structural members, and a plurality of additional support members secured within and between the vertical and horizontal extended supports connected to each other. to form, thus, the structure of armor. The full-core beam ring frames can be arranged in one or more directions within the fluid storage tank. Three exemplary arrangements include first, a group of full soul beam ring frames can be arranged extending along the width and height of the fluid storage tank and separated along the length of the fluid storage tank. Second, a group of full soul beam ring frames can be arranged extending along the height and length of the fluid storage tank and separated along the width of the storage tangue. Third, a group of full soul beam ring frames can be arranged extending along the length and width of the fluid storage tank and separated along the height of the fluid storage tank. The intersection of the full-beam girder ring frames extending in different directions can form a plurality of adhesion points where the filled-soul girder ring frames are interconnected in a different manner thus forming a frame structure integrated internal One or more of the full-core beam ring frame types described above may also include internal sides supported by the outer edge or ends of a frame structure as described above. Alternatively, one or more types of full-core beam ring frame may remain unsupported at its inner edge. Full-core girder ring frames may also include projections located on the inner sides of the full-core girder ring frame. The projections can be oriented in such a way that they form a "T" on the internal inner side of the web beam frames filled with the depth of the filled soul beam ring frames. The depth of a full-beam girder ring frame is defined as the distance between the edge of the inner side and the edge of the outer side of a full-beam girder ring frame in a plane containing both the inner side and the inner side. outer side of full soul beam ring frame. The protrusions can act to harden the full soul beam ring frames as half of an "I" beam. In one embodiment, full soul beam ring frames can be sized to have a depth of 1.0 to 4.0 meters. Alternatively, full-beam girder ring frames can have a depth of 1.5 to 3.5 meters or 2 to 3 meters. Again, depth is defined as the distance between the edge of the inner side and the edge of the outer side of the filled soul beam ring frame in a plane containing both the inner side and the outer side of the core beam ring frame full. In one embodiment, filled soul beam ring frames can have a depth that is 0.5 to 15 percent of the length, depth or height of the fluid storage tank. Alternatively, full-core beam-ring frames can have a depth of 1 to 10 percent or 2 to 8 percent of the length, depth or height of the fluid storage tank. In one embodiment, one or more of the filled soul beam ring frames may be solid along the depth for maximum support. In an alternative embodiment, one or more of the full-core beam ring frames may contain perforations. The perforations can be used to facilitate the flow of LNG through the sections created by the deep filled soul beams when the liquid level in the tank is low. As full-beam girder ring frames directed differently, the differently directed reinforcement structures may be included in the structure of the internal frame. The structures of the armor can be arranged in one or more directions within the fluid storage tank. Three example arrangements include, first, a group of reinforcement structures can be arranged extending along the width and height of the fluid storage tank and separated along the length of the fluid storage tank. Second, a group of reinforcement structures may be arranged extending along the height and length of the fluid storage tank and separated along the width of the storage tank. Third, a group of reinforcement structures may be arranged extending along the length and width of the fluid storage tank and separated along the height of the fluid storage tank. The intersection of the armature structures extending in different directions can form a connection between the armature structures directed differently so that both a first armature structure and a second perpendicular armature structure that intersect at a point of adhesion incorporate a structural member common in their respective structural configurations thus forming a structure of the integrated internal frame. In an embodiment of the intersection and connection of the armature structures directed in a different manner, it includes at least a portion of a vertical extended support that serves as a vertical extended support in both armor structures directed differently. In principle, the first directed armature structure and the second directed armature structure share a vertical armature member. The fluid storage tank also includes a plate cover that surrounds the structure of the internal frame. In one embodiment, the plate cover has an internal side disposed toward the outer sides of the included full-beam beam frames. In one embodiment, the fluid storage tank includes a plurality of interconnected stiffeners and bearers and arranged in a substantially orthogonal pattern. The plurality of reinforcements and stringers may have an internal and external side, where the outer side of the reinforcements and stringers is attached to the inner side of the plate cover and the reinforcements and stringers are intercostally connected to the soul beam ring frames. full. For example, the reinforcements and / or stringers may be attached to or integrally formed with the full-beam girder ring frames so that the outer sides / ends of both the full-soul girder ring frames and the reinforcements and / or stringers exist in the same plane. The plane formed by the outer ends / sides of both the full-beam girder ring frames and the reinforcements and / or spars provides, thus, a surface for the union of the inner side of the plate cover. In this way, both the outer edges of the full-beam girder ring frames and one side of the reinforcements and / or spars can be attached to the plate cover directly. In one embodiment, the stringers have a depth of 0.20 to 1.75 meters, alternatively of 0.25 to 1.5 meters, or alternatively of 0.75 to 1.25 meters. In one embodiment, the reinforcements have a depth of 0.1 to 1.00 meters, alternatively 0.2 to 0.8 meters, or alternatively 0.3 to 0.7 meters. In one embodiment, the plate cover is constructed to have a thickness of less than 13 mm (0.52 inches). In an alternative embodiment, the plate cover is approximately 10 mm (0.38 inches), alternately from approximately 6 mm (0.25 inches) to approximately 10 mm (0.38 inches) or between 6 (0.25 inches) to 13 mm (0.52 inches) of thickness. In one embodiment, the plate cover is composed of a plurality of joined plates. Using the ring frame described above and the armature structure, a fluid storage tank having an internal fluid storage capacity greater than 100,000 cubic meters can be constructed. Alternatively, the fluid storage tank can have a capacity greater than 50,000 cubic meters. Alternatively, the fluid storage tank can have a capacity greater than 150,000 cubic meters. If the fluid storage tank is used for cryogenic service, then the various components of the internal frame of the fluid storage tank and the cover may be of a cryogenic material that is suitably ductile and has acceptable fracture characteristics at cryogenic temperatures, such as it can be determined by a person skilled in the art. In one embodiment, the cryogenic material is selected from stainless steels, high nickel steel alloy, aluminum, and aluminum alloys. In one embodiment, any of the filled soul girder ring frames, the reinforcement structures or the plate cover are of a cryogenic material. It is expected that the filled core beam frame and reinforcement structure described above will be easier to construct and cost less than competing fluid storage tanks, especially for cryogenic fluid storage tanks. For example, full-beam girder ring frames can be formed of steel in plates or aluminum materials that should reduce the cost and not require complex additional formation of the steel structures. FIGURE 11 discloses an exemplary internal frame structure 250 in accordance with the full web girder frame / armor structure of the embodiment of the invention. The first full core beam ring frames 200 are shown extending along the width 210 and height 230 of the fluid storage tank and separated along the length 220 of the fluid storage tank. The first full-beam girder ring frames 200 are described with edges 235 of "T" -shaped internal sides. The first full-core beam ring frames 200 are described with first horizontal perforations 201 in the horizontal portions of the first full-beam beam frames 200 and first vertical perforations 202 in the vertical portions of the ring frames 200 full soul beam. The first full soul girder ring frames 200 are supported by the first reinforcement structures 203 corresponding to each of the first full girder beam frames 200 and are disposed in the plane of and within each first frame. 200 of full soul beam ring. The structure 250 of the internal frame also includes second frames 204 of filled soul beam ring extending along height 230 and length 220 of the fluid storage tank and which are spaced along the width 210 of the fluid storage tank. The second full-beam girder ring frames 204 are described with edges 236 on the inner side in a "T" shape. The second full-beam beam frames 204 are described with second horizontal holes 205 in the horizontal portions of the second full-beam beam frames 204 and second vertical-perforations 206 in the vertical portions of the second ring frames 204 of full soul beam. The second full web girder beam frames 204 are supported by second reinforcement structures 207 corresponding to each of the second full girder beam frames 204 and are disposed in the plane of and within each second frame 204 of full soul beam ring. The frame 250 of the inner frame also includes third full beam girder ring frames 208 that extend along the width 210 and length 220 of the fluid storage tank and are spaced along the height 230 of the storage tank of fluids. The third full-beam girder ring frames 208 are described with edges 237 of the internal "T" -shaped sides. The third 208 full-core girder ring frames are described with third horizontal holes 209 in the horizontal portions of the third full-girder beam frames 208 extending in a direction along the length. The horizontal portions of the third full-girder beam frames 208 extending in a direction along the width do not contain any perforations and are solid. The third full-beam beam ring frames 208 are not supported by a separate coplanar frame structure as with the first and second full-beam beam frames.

The full web beam adhesion points 211 are formed at the intersection of the filled web girder ring frames in various manner. By joining, for example by welding, the filled web girder beam frames in a different manner a structure 250 of the stiffer internal frame is obtained. In the same way, the intersections of the first armor structure 203 and the second armor structure 207 form points 212 of adhesion of the armor. By joining, for example by sharing the structural members, the armature structures directed perpendicularly, a structure 250 of the stiffer internal frame is obtained. FIGURE 12 describes the structure 250 of FIGURE 11 of the internal frame with additional reinforcements and spars partially covering the structure 250 of the internal frame. The first stiles 221 are shown extending along the width 210 and height 230 of the fluid storage tank and separated along the length 220 of the fluid storage tank.

The third spars 224 are shown extending along the length 220 and height 230 and spaced along the width 210 of the fluid storage tank. FIGURE 12 also describes reinforcements 223 that extend orthogonally to either first, second or third stringers 221, 222, 224. Reinforcements 223 may be connected to either first, second or third stringers 221, 222, 224. As shown in FIG. shown in Figure 12 the reinforcements 223 and stringers 221, 222, 224 can be integrally joined or formed with the full-beam girder ring frames so that the outer sides / ends of both the full-girder beam-frame frames and the reinforcements and stringers exist in the same plane. The plane formed by the outer ends / sides of both the full-beam beam frames and the reinforcements and spars thus provides a surface for joining the inner side of the plate cover. In this way, both the outer edges of the filled soul girder ring frames and one side of the reinforcements and / or spars can be attached to the plate cover directly. Alternatively, the inner side of the stiffeners and stringers can be attached to the outer sides of the full-core beam girder chassis directed in a variety of ways. The outer side of the stiffeners and stringers may be attached to the inner side of the plate cover 231 as described in FIGURE 13. FIGURE 14 describes a filled core beam ring frame that is representative of the beam ring frame 200. filled web described above which extends along the width 210 and height 230 of the fluid storage tank and separated along the length 220 of the fluid storage tank. The filled soul beam 200 has an inner side 241 disposed towards the interior of the fluid storage tank, including in some embodiments toward the outside of the internal frame structure and an external side 242 disposed towards the outer portions of the frame structure internal of the fluid storage tank. The depth 243 of the full web beam frame 200 is the distance between the edge of the inner side and the edge of the outer side of the full beam beam frame 200. The filled core girder ring frame of FIGURE 14 is solid and does not contain perforations. The lines located in the first full web beam ring frame 200 describe where the second filled beam beam frame 204 and the third full web beam frame 208 would intersect with the first ring frame 200 of full soul beam.

The left half of the full web girder ring frame 200 is described with an internal reinforcement structure representative of the first reinforcement structure 203, while the right half of the full girder beam frame 200 is described without any structure of internal armor. The frame structure 203 may be comprised of a plurality of either vertical extended supports 244 or horizontal extended supports 245, connected to form a framework of structural members, and a plurality of additional support members 246 secured within and between supports 244 , 245 extended vertical and horizontal connected. FIGURE 15 describes a portion of a fluid storage tank 260 made of full-core beam ring frames. The portion of the fluid storage tank 260 described is comprised of a top panel member 261, an end panel member 262, a bottom panel member 263, and two side panel members 264. The various panel elements include plate covers 231, reinforcements (not shown), respective spars (not shown), and respective full core beam ring frames 200, 204, and 208 (numbered as a, b, e and e to distinguish the portions in the ring frames located in different panel elements). The panel elements including the structural elements described above may be constructed in one location, moved to a second location, and assembled in the second location. During assembly the internal reinforcement structures can be added to form the structure of the internal frame of the fluid storage tank. FIGURE 16 shows how the various panel elements can be stacked for boarding from the first place to the second place. Referring to FIGS. 5A and 5B, for manufacturing purposes, excluding some inner armor members that must be installed later (shown in FIGURE 5C), a tank is initially constructed according to some embodiments of this invention as four sections 81a , 82a, 82b and 81b separated (section 81b is shown in an exploded view in FIGURE 5B and section 82b is shown in an exploded view in FIGURE 5A), with each of the two middle sections 82a and 82b comprising four panels each, i.e., an upper panel 83, a lower panel 84 and two side panels 85, and each of the two end sections 81a and 81b comprising five panels each, a top panel, a bottom panel , two side panels, and another panel referred to as a third side panel or an end panel 87. In this illustration, the longest panel, for example, panel 83 for a middle section 82a or 82b comprises one or more plates 86 joined together, reinforcements and / or spars (not shown) and parts of members 88 of the structure of the structure. internal armor frame. The panels (eighteen in number in the present illustration) are manufactured first and assembled in a tank unit as discussed below. In one embodiment, panel manufacturing begins with the delivery of plates to a shipyard where the plates are marked, cut and manufactured into plate covers, reinforcements, stringers and member members of the frame structure of the frame. The panel elements are joined together by any applicable joining technique known to those skilled in the art, for example, welding, and the reinforcements, stringers, and frame elements of the frame are joined to the panel in the sub-assembly lines and assemble normally used in modern shipyards. Once the manufacturing operation is complete, the panels for each section of the tank are stacked separately as indicated in FIGURES 6A and 6B. For example, they are stacked as shown using the same numbering for the average section 82b of FIGURE 5A and 5B, upper panel 83, side panels 85, and lower panel 84. Referring now to FIGURE 7, the sets of the four stacked panels comprising the four sections 81a, 82a, 82b and 81b of the tank illustrated in FIGURE 5B, together with the additional structural members of the frame structure of the frame (not shown) in FIGURE 7) that must be installed in the field while the panels are assembled to build the structure of the tank, they are loaded on a barge 100 from the high seas and transported to the site of the construction of the tank. The end panels are not shown in FIGURES 7 and 8, but they are also loaded on the offshore barge 100. Referring now to FIGURE 8, at site 102 of the tank construction, the sets of the four stacked panels comprising the four sections 81a, 82a, 82b, and 81b and the additional armor structural members (not shown in FIG. 8) are unloaded and moved to the tank assembly site 104 near the traction tractor tracks 110, track paths 112, and secondary container 117. At tank assembly site 104, the panels for each section of the tank unfold and join to create each section of the tank. For example, the unfolding and joining of panels 83, 84, 85 to make section 82b (as shown in FIGURES 5A and 5B) is shown in the FIGURES 9A and 9B. With the panel 83 raised, the sides 85 are folded on the outside until they are substantially vertical, and then the panel 83 is lowered and joined to the sides 85. In this step, the frame members of the partial additional armature frame are installed in the inside of the tank both in the direction of the length and width of the tank (an example of this frame is shown by dotted lines in FIGURES 3 and 4). In one embodiment, the four sections 81a, 82a, 82b, and 81b are then assembled into the tank assembly site 104 and joined together, eg, by welding, to form a partially finished tank 115 as shown in FIGURE 10A and a tank 116 terminated as shown in FIGURE 10B. In the embodiment illustrated in FIGURE 10B, the finished tank 116 is tested for gas and liquid tightness and dragged to the place within the secondary container 117. Referring again to FIGS. IB and 1C, due to the opening of the structure 18 of the internal armor frame, the interior of a tank according to an embodiment of this invention, such as tank 10 of FIGURE 1, is effectively contiguous along the tank so that the LNG or other liquid stored therein is free to flow from end to end without any effective charge in between. This inherently provides a tank that has more effective storage space than the one present in the same size tank with bulkheads. Another advantage of a tank according to this invention is that only a single set of tank penetrations and pumps are required to fill and empty the tank. More importantly, due to the relatively long and open intervals of the tank 10 of the present invention, any spillage of the stored liquid caused by seismic activity causes relatively small dynamic loads in the tank 10. This load is significantly smaller than it would be if the tank had multiple cells created by the bulkheads of the prior art. The filled web girder ring frame and the armor structure liquid storage tank of the embodiment of the invention can also be assembled by any of the methods described above for the mere embodiment of the liquid storage tank of the reinforcing frame. . In that assembly, portions of a full web girder ring frame could be attached to a respective side or section of the end plate cover to form the panel elements. The portions of a filled web girder ring frame could then be connected as sections of the plate cover sections or panel elements are connected by, for example, welding the sections of the respective full core girder ring frame. to form a global filled web beam frame. Different types of structural modules can be formed from the full-core girder ring plate / frame cover formed as described for the mere previous embodiment of the liquid storage tank of the reinforcement frame for use as end sections and middle sections as it is described for the mere embodiment of the liquid storage tank of the armor frame. For example, a rectangular fluid storage tank can be considered to comprise four substantially equal structural modules obtained by cutting a long tank in three imaginary vertical planes suitably spaced along the length direction so that each section is conceptually capable of containing about a quarter of the liquid storage volume. Such a tank is composed of two substantially identical end sections and two substantially identical middle sections. When removing or adding middle sections during the construction of the tank, tanks of the same cross section can be obtained, in different stages, that is, same height and width, but variable length and, thus, variable capacity. Although this invention is very convenient for storing LNG, it is not limited thereto, rather, this invention is suitable for storing any liquid at cryogenic or other liquid temperature. Additionally, while the present invention has been described with respect to one or more preferred embodiments, it should be understood that other modifications may be made without departing from the scope of the invention, which is set forth in the claims below. All tank dimensions given in the examples are provided for illustrative purposes only. Various combinations of width, height and length can be invented to build tanks in accordance with the teachings of this invention.
