Abstract
A perforating gun loading and storage facility is disclosed. In one aspect of the present disclosure, the perforating gun loading and storage facility includes, a floor without venting, a roof comprising a layer of steel and a vent for energy release, and a set of external walls enclosing a region between the floor and the roof forming an internal region within which a perforating gun is to be loaded and handled; each of the set of external walls having a layer of steel.
Description
- This application claims priority to U.S. Provisional Patent Application No. 61/087,661 entitled “Jet Perforating Gun Loading and Storage Facility”, which was filed on Aug. 9, 2008, the contents of which are expressly incorporated by reference herein.
- Gun loading facilities typically carry large amounts of explosives in magazines and inside loaded guns. Personnel also access the loading facilities to transport explosives and/or to load guns. In a gun loading facility, guns are brought into a loading area and set on a bench or table. The guns are then disassembled and installed with explosives carried over from the magazine. Once the guns have been loaded, they are subsequently reassembled and in some instances, placed onto a rack for holding loaded guns.
- However, gun loading facilities may be located within or around other facilities and equipment including but not limited to, working individuals, offices, vehicles, gas pipes, electrical wiring, etc. In the event of accidental detonation of the explosives in the gun loading facility, damage to surrounding areas and risk of injury to personnel and equipment is often severe. For example, debris and fragments, and in particular, sharp debris created from an explosion can be accelerated outwards and injure nearby personnel. Furthermore, underground structures such as gas pipes may be damaged. The exposure of gas to excessive heat may cause an additional source of explosion.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. In the case of conflict, the present document, including definitions will control.
- Embodiments of the present disclosure include a perforating gun loading and storage facility, generally having a steel frame structure with a steel plate external cladding.
- In one aspect, the gun loading and storage facility has a floor, a roof comprising a single layer of steel and a vent for energy release, and a set of external walls enclosing a region between the floor and the roof forming an internal region within which a perforating gun is to be loaded and handled. Each of the set of external walls includes at least a layer of steel. The set of external walls are configured to remain substantially intact when explosives in the internal region are detonated.
- Note that, in general, the flooring is made from solid pieces of concrete and does not include vents, openings for vents, or in most instances, openings for any other purposes other than to facilitate robust connections between multiple pieces of concrete that make up the floor (e.g., concrete footings and concrete slabs).
- Note further that, although the roof includes a layer of steel, the roof generally does not have the need for a shock and/or energy absorbing material and is formed, in one embodiment, without any shock and/or energy absorbing material (e.g., gravel, plywood, steel, and/or the like materials,) attached thereon or embedded therein, to obtain the desired blast resistance characteristics. The steel layer can be attached to a hollow structural section which is typically further connected to a layer of wood (e.g., plywood).
- In one aspect, the facility is designed to remain intact and/or to contain the internal explosion when accidental detonation of explosives occurs. In particular, the facility is capable of remaining intact when a net explosives quantity (NEQ) of approximately up to 30 kg-TNT detonates within the structure and the explosives may be located in the storage area (e.g., magazine area) and/or the processing area (e.g., the gun loading area). The derived structural response of the building under these maximum detonation conditions implicates that the internal explosion is contained within the facility without failure. In addition, the fragments and debris (e.g., sharp, hazardous building fragments) do not accelerate past a predetermined standoff distance.

FIG. 1A illustrates atop view 100 of the example layout of a gun loading and/orstorage facility 102 showing thestorage area 103 and theprocess area 105, according to one embodiment. - The gun loading and
storage facility 102 is generally designed and built such that the internal region is suitably sized for including at least thestorage area 103 and theprocess area 105, allowing, for example, personnel to carry unloaded guns into thefacility 102 for loading or storage purposes. The size and layout of thefacility 102 may be such that it is sufficient for personnel (e.g., authorized and/or trained personnel) to carry explosives within thefacility 102 to/from different areas for storage and/or loading purposes. - For example, during the gun loading process, unloaded guns may be placed on the work table while personnel disassemble the gun. The personnel may further carry explosives from the magazine to the work table, install the explosives in the gun, and proceed to reassemble the gun, after which the guns become loaded and can be carried to and placed on the completed
gun rack 108 for storage. Thus, thefacility 102 should typically accommodate for working space, walking space, and storage space, as depicted, for example, by thestorage area 103 and theprocess area 105. - The
process area 105 can includemagazines 104A/B in which the explosives, ammunition, bombs, and/or other explosive materials for guns or other types of weapons are to be stored. In one embodiment, the magazines are at least partially enclosed (e.g., enclosed on three sides) by a magazine wall (e.g., a concrete magazine wall). In the example ofFIG. 1A , themagazine 104A is enclosed on at least three sides by themagazine wall 119. Themagazine 104B is also enclosed on at least three sides by themagazine wall 119. Themagazine wall 119 has a continuous elongated portion opposite to a side of access to the first andsecond magazines 104A/B. In one embodiment, themagazine wall 119 is formed from substantially concrete and/or any additional robust or blast resisting material including but not limited to steel, gravel, plywood or any combination of the above that is suitably dense for stopping debris and absorbing shock energy. - The
process area 105, in one embodiment, includes holdingracks 106A/B for holding unloaded guns and/or other types of weapons and a work table 118 on which the guns/weapons may be placed when being loaded with explosive material. In general, themagazines 106A/B and the loaded gun racks 108 can safely store, up to and/or slightly exceeding a total of at least 120 kg of explosives and ensure the blast resistance in the event that all or most of the explosives accidentally detonate. For example, eachmagazine 106A/B is designed to withstand approximately 30 kg TNT+/−5-10%. Each of thestorage area 103 andprocess area 105 is designed withstand approximately 30 kg TNT+/−5-10%. - The required Q-D standoff distances computed for 120 kg TNT placement described is illustrated in Table 1 of
FIG. 1C for pressure of 1.34 PSI and 0.74 PSI in the front, rear and sides of the gun loading/storage facility. A graphical depiction of the position of the ‘front’ and ‘other’ sides of the gun loading/storage facility is illustrated in the example ofFIG. 1D . A graphical illustration of the constant pressure contours surrounding the gun loading/storage facility associated with the Q-D standoff distances listed in table 1 is depicted in the example ofFIG. 1E . - The
storage area 103 may further include aholding rack 108 for loaded guns and/or other types of weapons. Aninterior wall 117 typically separates thestorage area 103 and theprocess area 105 and can be, for example, connected to themagazine wall 119 and the set of walls (external walls around the parameter of the facility enclosing an internal area within). Theinterior wall 117 typically includes a steel layer and the structure of which is illustrated in detail with further reference to the example ofFIG. 5 . - The
interior wall 117 can serve to isolate thestorage 103 andprocess 105 areas and protect personnel working in theprocess area 103 from any accidental detonations that may occur in the storage area 105 (e.g., the holding racks for loaded guns 108). For example, theinterior wall 117 allows the facility to withstand each of thestorage 103 andprocess 105 areas to withstand at least 30 kg TNT+/−5-10%. - In addition, the
facility 102 includes apersonnel door 110 and adoor barrier 112 disposed a predetermined distance from thepersonnel door 110. Thepersonnel door 110 is, in one embodiment, 3-ft W×6-ft L although other dimensions may be used. For example, thepersonnel door 110 could have a smaller width or greater width that is designed to withstand predetermined amounts of pressure. The physical configuration and placement of thedoor barrier 112 relative to thepersonnel door 110 is illustrated and described with further references to the examples ofFIG. 6 andFIG. 11 . - The
door barrier 112 placed in front of thepersonnel door 110 can prevent fragments from being blasted beyond predetermined standoff distances. In one embodiment, thepersonnel door 110 is located adjacent to the processing area to allow ease of access of the personnel loading or unloading guns to the processing areas without having to pass through the areas where explosives are typically stored (e.g., themagazines 104A/B and/or the holding rack for loaded guns 108). - In one embodiment, the
facility 102 further optionally includes apipe entrance door 114A adjacent to theprocessing area 105 and adoor barrier 116A displaced a predetermined distance from thepipe door entrance 114A. Thefacility 102 further optionally includes apipe exit door 114B adjacent to thestorage area 105 and anotherdoor barrier 116B displaced a predetermined distance from thepipe exit door 114B. Thepipe entrance doors 114A and/or 114B can be used to load and unload guns into thefacility 102. Note that thepersonnel door 110 may be used to transport loaded/unloaded guns into and/or out of thefacility 102 thus the pipe entrance/exit doors 114A/B are optional. Similarly, personnel may enter/exit through pipe entrance/exit doors 114A/B. Therefore, thepersonnel door 110 is optional when personnel can enter/exit thefacility 102 via the pipe entrance/exit doors 114A/B. - Note that the
doors personnel door 110 and the pipe entrance/exit doors 114A/B are Type 4 “NRCan Standards” vault doors that are designed to be opened from the interior of thefacility 102. In general, thedoors -
FIG. 1B illustrates aview 150 of an example layout of the gun loading and/orstorage facility 102 showing the roof vents 122, according to one embodiment. - The roof vents 122 are disposed on the roof and are designed to be blown open or otherwise displaced in the event of detonation for release of explosion energy. The placement of roof vents 122 are illustrated with further reference to the example of
FIG. 9A . Although six vents are illustrated, any number of roof vents 122 may be used on the roof and is considered to be within the scope of the disclosure. - In one embodiment, the roof vent 122 (e.g., vent, blow out panel, etc.) is made from a light-weight material (e.g., light-weight panel) sealed to the roof that can break a part in the presence of pressure. The light weight material is generally not made from glass but from plastics or other polycarbonate materials. In addition, a layer of steel grating may be disposed exterior to the top of the light-weight panel. The steel grating allows pressure to exit but retains any particles and/or debris within the facility. In the example of
FIG. 1B , two vents are oriented over each of themagazine 104A/B, the work table 118, and the holding rack for loadedguns 108, respectively. -
FIG. 2 illustrates aside view 200 of an example of the main frame section of the gun loading and/or storage facility, according to one embodiment. - The
side view 200 shows the facility having aroof 210, a set ofwalls 206, an interior wall 208 (e.g., interior fragment mitigation wall),footing sections 202A/B, andfloor slabs 204. Thefooting 202A/B andslabs 204 form the flooring and is typically comprised substantially of concrete. For example, the floor includes afirst footing 202A having four sides surrounding a parameter of the facility and a secondconcrete footing 202B. - The
second footing 202B is generally within the parameter of the facility is connected to two opposite sides of the four sides of the external walls, see for example,FIG. 7A . Theconcrete footings 202A/B are typically each approximately 2.5-ft×4.5-ft.Concrete slabs 204 are connected to and between the first and second footings via steel reinforcement. Theconcrete slabs 204 can be approximately 4-inch thick. Note that the flooring is formed from substantially concrete and/or other types of solid/robust material and does not include openings for vents, blow-out panels, or other openings for the like purposes. Note that alternatively, the flooring may include in-floor heating (e.g., a hydrophonic heating system). The in-floor heating is heated by a boiler that is piped out of the facility and obviates the need for a rough-neck heater which may spark and cause a fire in the event of an explosion. - The frame structure typically includes a steel frame. In one embodiment, the steel frame is configured such that the main section is constructed from combining two
halves halves center support 218 to reinforce the connection. In one embodiment, thewall column 206 androof beam 210 are comprised of hollow structural sections (HSS). In one example, the HSS are 12×4×½″ steel sections (A500 Grade B) that are spaced apart from one another by approximately 4-ft on the center. The A500 Grade B steel is advantageous in that columns and beams formed from such material have been determined to have a yield strength of approximately 46-ksi. In one embodiment, the frame sections are spaced part from one another by approximately 2-ft on the center near the section of the building where the magazines are located. - In addition, a
roof beam 216 spans the length of the building at the crown of theroof 210. In one embodiment, theroof beam 216 is formed from a hollow structural section. The HSS is, in one embodiment, a 13×4×½″ steel section. One embodiment includes secondary roof beams to connect the roof beams to each other (not visible inFIG. 2 ) that span between each roof beam. The secondary roof beams are typically located where the exterior steel plate is connected to each other. -
FIG. 3 illustrates asectional view 300 of theexternal wall 306, according to one embodiment. - The external walls of the perforating gun loading and storage facility enclose a region between the floor and roof forming an internal region within which guns and/or other types of weapons can be disassembled, assembled, loaded, unloaded, and otherwise handled. Each of the set of external walls, for example, can include a layer of steel and is designed to be blast resistant in the event of detonation of explosives inside the facility. Under most circumstances, the external walls remain substantially intact when explosives in the internal region of the perforating gun loading and storage facility are detonated. For example, the set of external walls are to remain substantially intact when explosives of up to approximately or near 30-kg TNT are detonated.
- In general, the
external wall 306 is constructed to prevent intrusion from the exterior of the perforating gun loading and storage facility. For example, a Type 4 Magazine wall is preferably used for such purposes. Alternatively, Type I, II, and/or III Magazine walls may be used. In one embodiment, theexterior wall 306 includes a layer of steel 302 (e.g., ¼″ plate) connected to a hollow structure section (HSS) 312 (e.g., 12×4×½″) on one side of theHSS 312. Another layer of material 304 (e.g., ¾″) may further be connected to the internal side of theHSS 312. Thelayer 304 may be although is not limited to plywood. One embodiment further includes an optional layer of spay-on foam for heat insulation (e.g., to retain the heat building) adjacent to the internal side of the layer ofsteel 302. - Furthermore, the
external walls 306, in one embodiment, are filled with shock absorbing material to absorb the energy released during detonation and to limit lateral distribution of debris cause by explosion. The shock absorbing material can include, but is not limited to, gravel, cement, wood, fiberglass, and/or polymers. In one embodiment, the shock absorbing material is filled in theexternal walls 306 to a height of approximately 7-ft or another suitable line of sight height. - The corner joins of the
external walls 306 can be reinforced with a steel angle to prevent the corners from failing in the event of pressure build up inside the facility. For example, the steel angle can have the dimensions of L3×3×¼″. Additionally, a steel strip (e.g., 2-inch wide and ¼″ thick) can be attached to the exterior plate seams of the external walls. The steel strip is preferably continuously welded to the plating although other mechanisms of assembly maybe used. -
FIG. 4 illustrates asectional view 400 of theroof cladding 410, according to one embodiment. - The roof can be formed from a layer of steel and includes vents or vents having blow-out panels for release of energy during an explosion. The layout of the vents are illustrated with further reference to the example of
FIG. 9A . The roof is designed for energy release and for minimization of the distance of outwards travel of debris and/or to prevent fragments from exiting. In one embodiment, theroof cladding 410 includes a layer of steel 402 (e.g., ¼″ plate) connected to one end of an HSS 414 (e.g., 12×4×½″). A layer of plywood 404 (e.g., ¾″) may further be connected to the opposite end of theHSS 414 and is disposed internal to the layer ofsteel 402. - In addition, a steel strip (e.g., 2-inch wide and ¼″ thick) can be placed at the exterior plate seams of the
roof 410. In one embodiment, exterior plating is used to ensure continuity at the wall to roof connection and at the crown of the roof. In one embodiment, a steel angle (e.g., L3×3×¼″) is used to reinforce the exterior plating seam where the end wall and theroof 410 are connected. - Note that, in general, the
