     FIELD OF THE INVENTION 
     The invention relates generally, but not limited, to an oil recovery system. More particularly, the invention relates to an atmospheric, terrestrial, and/or oceanic structure that may be used for, but not limited to, oil containment and recovery. This invention may be used prior to the exploration of oil in oceans, thereby mitigating the spill at the onset. 
     BACKGROUND OF THE INVENTION 
     Crude oil is a popular source of energy for vehicles such as cars, trucks, motorcycles, and airplanes. There are various other uses for crude oil and products refined therefrom. 
     Typically, the crude oil is obtained from a well that is drilled beneath a surface of the ground. In addition to the wells being drilled into the ground on one of the continents, it has also been recognized that wells can be drilled into the ground located beneath bodies of water. 
     It is generally desired to collect substantially all of the crude oil that is extracted from a well to maximize the income generated from the well and to minimize the negative effects that are experienced when the oil escapes into the region surrounding the well. 
     While oil drilling technology enables drilling wells into very deep bodies of water such as having a depth of greater than about 5,000 feet, it becomes increasingly difficult to address issues that may develop at these depths. For example, it is generally not possible for humans to perform directly tasks at these depths. Rather, the immense pressures at these depths necessitate that the work be done using robotically controlled devices. 
     Even in situations where safety devices such as blowout preventers are utilized to address problems that may arise when drilling wells at these depths, it is possible that the safety devices may malfunction and that the crude oil may escape from the well and become intermixed with the body of water in which the well is located. 
     The presence of the crude oil in the water can be a health hazard to organisms that live in the body of water not only causing death to the organisms but also precluding the use of the organisms as a food source. The crude oil can also contaminate that shore that surrounds the body of water and thereby preclude the use of the shore for recreational activities. 
     In view of the hazards associated with crude oil escaping into a body of water, it is desirable to utilize a system that provides the ability to contain the crude oil that escapes during the drilling process such that the escaped crude oil may be recovered. 
     Most past efforts and equipment designed for these purposes were based upon the principle that you needed a large heavy mass (i.e., a 100-ton concrete dome) to capture the oil and withstand the pressure at more than 5,000 feet below sea level. It has also been attempted to utilize methods that work above sea level. However, such methods do not consistently work below sea level because of the pressures that exist at those depths. 
     SUMMARY OF THE INVENTION 
     An embodiment of the invention is directed to an oil containment recovery dome that includes an upper containment portion and at least one bladder. The upper containment portion has an enclosure defined therein that is adapted to receive equipment used in conjunction with a well and to retain therein oil or gas that escapes from the well. The at least one bladder is attached to the upper containment portion. 
     Another embodiment of the invention is directed to a method of containing and recovering oil or gas that leaks from a well that is located beneath a surface of a body of water. An oil containment recovery dome that includes an upper containment portion having enclosure defined therein that is adapted to receive equipment used in conjunction with a well and to retain therein oil or gas that escapes from the well. The oil containment recovery dome is transported to a location where a well is located. The oil containment recovery dome is moved into a position over the well. 
     Another embodiment of the invention is directed to an oil containment and recovery system that includes an oil containment recovery dome and a transport vehicle. The oil containment recovery dome includes an upper containment portion having enclosure defined therein that is adapted to receive equipment used in conjunction with a well and to retain therein oil or gas that escapes from the well. The transport vehicle is capable of moving the oil containment recovery dome to a location where the oil containment recovery dome is used.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     An embodiment of the invention is directed to an oil containment recovery dome as illustrated at  100  in the figures. The oil containment recovery dome  100  is particularly suited for use in conjunction with an oil well that is to be drilled below a body of water. 
     In certain embodiments, the oil containment recovery dome  100  is used in conjunction with deep-water oil wells such as those drilled in water having depths of more than about 500 feet. In other embodiments, the oil wells are drilled in water at a depth of more than 5,000 feet. 
     In still other embodiments, it is possible to use the oil containment recovery dome  100  in conjunction with wells that are in relatively shallow water where it is especially desirable to minimize the potential of oil or gas escaping from the well into the water. 
     The oil containment recovery dome  100  is positioned on a ground surface beneath the body of water such that any oil or gas that escapes from the oil well is substantially contained within the oil containment recovery dome  100 . Containing the oil within the oil containment recovery dome  100  facilitates recovering the oil and gas to minimize the potential of negative environmental impact from the oil. 
     Oil and gas that is contained within the oil containment recovery dome  100  may be directed to tankers that are positioned on the water surface proximate the oil containment recovery dome  100  such as using at least one conduit or feeder line. 
     The oil containment recovery dome  100  should be formed with sufficient strength to withstand damage and/or movement. The oil containment recovery dome  100  may also have sufficient strength to withstand pressure developed within the oil containment recovery dome  100  caused by accumulation of oil there within. In certain embodiments, at least a portion of the oil containment recovery dome  100  has a geodesic shape, as illustrated in  FIGS. 1 and 2 . 
     The oil containment recovery dome  100  may be formed with a size that is sufficiently large to encompass not only the oil drilling equipment positioned on the ground surface of the body of water but also to encompass a large percentage of oil that could potentially leak from the oil well before such leaked oil could be recovered, as illustrated in  FIG. 27   a.    
     In certain embodiments, the oil containment recovery dome  100  has a diameter of between about 50 feet and about 300 feet. In other embodiments, the oil containment recovery dome  100  has a diameter of about 500 feet. 
     The oil containment recovery dome  100  may generally include an upper spherical section  101  and a lower cylinder section  102 . The upper spherical section  101  may have a generally geodesic shape, as illustrated in  FIGS. 1 and 2 . The upper spherical section  101  and lower cylinder section  102  may be formed from a plurality of the first structural beams  113  and the second structural beams  114  that are attached together using first attachment assemblies  105  and second attachment assemblies  106 , as illustrated in  FIGS. 5 and 7 . 
     An outer dome section has a diameter that is slightly larger than an inner dome section diameter, as illustrated in  FIGS. 3 ,  4 ,  5  and  7 . This dome configuration has been referred to as a double resonated dome. 
     An advantage of using this configuration is that a force placed on the outer dome section is distributed to the inner dome section. This process increases the strength of the oil containment recovery dome  100  to thereby minimize the potential that the force results in damage to the oil containment recovery dome  100 . 
     In one such configuration, the inner dome section has structural elements that are arranged in a hexagonal configuration and the outer dome section has structural elements that are arranged in a triangular configuration. 
     As is discussed in more detail herein, the outer dome section may include two types of structural elements. The first structural elements may be arranged in a hexagonal configuration. The second structural elements may be arranged to define six triangles within each of the hexagons defined by the first structural elements. 
     While it is illustrated that the first structural elements are wider than the second structural elements, it is possible for other configurations to be used. An example of one such alternative configuration is where the first structural elements and the second structural elements are formed with a substantially similar width. 
     In certain embodiments, the first structural beam  113  and the second structural beam  114  are attached together in a generally triangular configuration and, the first structural beam  113  are attached together in a generally hexagonal and or polygonal configuration. In certain embodiments, at least portions of the triangles are acute triangles, equilateral triangles, and isosceles triangles, as illustrated in  FIG. 5 . 
     The first structural beam  113  and the second structural beam  114  may be fabricated from a variety of materials using the concepts of the invention. The first structural beam  113  and the second structural beam  114  should resist degradation when exposed to the conditions under which the oil containment recovery dome  100  is intended to be used. For example, if the oil containment recovery dome  100  is intended to be used in an ocean, the first structural beam  113  and the second structural beam  114  should resist degradation caused by salt and organisms that are conventionally present in ocean water. 
     In certain embodiments, the first structural members beam  113  and the second structural beam  114  may be fabricated from a metallic or polymeric material. It may be desirable to fabricate the first structural beam  113  and the second structural beam  114  from materials that have a relatively high strength as well as being relatively lightweight. Forming the structural members from materials having these characteristics enhances the ability to move the oil containment recovery dome  100  even if the oil containment recovery dome  100  has a relatively large diameter and/or height. 
     Examples of such suitable materials include steel containing additives that reduce the degradation of the steel when the steel is exposed to the salt and organisms conventionally found in ocean water. In certain embodiments, the first structural beam  113  and the second structural beam  114  are fabricated from stainless steel, titanium, magnesium and fiberglass or fiber composites. 
     The first structural beam  113  and the second structural beam  114  should have sufficient strength to resist deformation based upon the conditions under which the oil containment recovery dome  100  is intended to be used. Factors potentially affecting such strength include the diameter of the oil containment recovery dome  100  and the length of the structural members  113  and  114 . 
     In certain embodiments, the first structural beam  113  and the second structural beam  114  have a length of between about 2 feet and about 12 feet. In other embodiments, the first structural beam  113  and the second structural beam  114  have a length of between about 3 feet and about 8 feet. 
     In certain embodiments, the first structural beam  113  and the second structural beam  114  may have a generally square, round, I-beam, H-beam, or rectangular profile with a height and a width that are both between about 1 inch and about 24 inches. In other embodiments, the height and the width of the first structural beam  113  and the second structural beam  114  are both between about 2 inches and about 24 inches. 
     In certain embodiments, the first attachment assembly  105  and the second attachment assembly  106  may have a generally circular configuration, as illustrated in  FIGS. 5 and 7 . An outer skin  110  of the second attachment assembly  106  may be used for attaching the first structural beam  113  and the second structural beam  114 , as illustrated in  FIGS. 5 and 7 . 
     A variety of techniques may be used for attaching the first structural beam  113  and the second structural beam  114  to the first attachment assembly  105 . Examples of two such connection techniques are bolts and welding. 
     While the figures illustrate that there are six of the first structural beams  113  and the second structural beam  114  attached to the first attachment assembly  105 , a person of skill in the art will appreciate that other numbers of first structural beam  113  and the second structural beam  114  may be attached to the first attachment assembly  105 . An example of one such alternative configuration is attaching five of the first structural beams  113  and second structural beam  114  to the first attachment assembly  105 . Another example of one such alternative configuration is attaching three structural members  113  to the second attachment assembly  106 . 
     A cap section  104  of the oil containment recovery dome  100  may be separable from the other portions of the oil containment recovery dome  100 . Such a configuration enables relatively large size objects to be placed within the oil containment recovery dome  100 . An example of one such relatively large size object is a super blowout preventer. The cap section  104  may split, be but limited, into multiple configurations as illustrated in  FIG. 6 . 
     The cap section  104  may be fabricated similar to the other aspects of the upper sphere section  101  in that the cap section  104  includes a plurality of the first structural beam  113  and the second structural beam  114  that are each attached to the first attachment assembly  105  and the second attachment assembly  106 , as illustrated in  FIGS. 5 ,  6  and  7 . 
     The cap section  104  may also include a plurality of outer skin  110  and inner skin  111  attached to an upper surface thereof. The outer skin  110  may have a generally triangular shape so that each of the outer skin  110  substantially covers an opening between adjacent first structural beam  113  and the second structural beam  114 . 
     The outer skin  110  and inner skin  111  may be fabricated from a variety of materials using the concepts of the invention. The outer skin  110  and inner skin  111  should have sufficient strength to resist deformation and breakage under the conditions at which the oil containment recovery dome  100  is utilized. 
     In certain embodiments, the outer skin dome assembly  110  may be fabricated from a different material than the inner skin dome assembly  111 . An example of one such configuration is that the outer skin dome assembly  110  is fabricated from a stronger material than the material used to fabricate the inner skin dome assembly  111 . 
     The outer skin  110  should also resist degradation when exposed to the materials in which the oil containment recovery dome  100  is used such as salt and organisms present in ocean water. Examples of two such materials that may be utilized to fabricate the outer skin  110  are metallic or polymeric sheets. The outer skin may be porous like a cage structure when the inner skin  110  is functioning to contain an oil leak. 
     A variety of techniques may be used to attach the outer skin  110  and the inner skin  111 . As is discussed in more detail below, the technique used to attach the outer skin  110  and inner skin  111  to the other elements of the sphere  101  and the cap section  104  need only be capable of containing oil within by means of one of the skins. 
     An example of one such suitable technique to attach the outer skin  110  to the other portions of the cap section  104  is by positioning the edges of the outer skin  110  between the structural beam  113  and structural beam  114  and a seam covering cap (not shown) and then using a fastening device such as a screw or bolt to attach the seam covering cap to the first structural beam  113  and structural beam  114 . 
     In certain embodiments, an ocean resistant material with porous pattern may be used for the outer skin  110  in conjunction with the oil containment recovery dome  100 . Such a porous material may be similar to metal cyclone fencing and may prevent sea creatures from entering the interior of the oil containment recovery dome  100 . 
     As illustrated in  FIGS. 5 and 7 , the first attachment assembly  105  may also accept mooring anchors  115  and cables  117  such as are illustrated in  FIG. 2 . The first attachment assembly  105  is structurally capable to accept matching connectors (not shown) to be used with attachments for transport of the oil containment recovery dome  100  to and from the installation site by air, surface sea or below sea surface as illustrated in  FIGS. 12 ,  13 ,  15 ,  18 ,  25 ,  26   a  ,  26   b,    27   a  ,  30  and  31 . 
     As illustrated in  FIGS. 5 and 7 , the second attachment assembly  106  may accept a plurality of quick release accessories (not shown). The second attachment assembly  106  is able to receive a matching connector (not shown) for a pipe, feeder line, or other conduit (not shown) that is used to transport the oil from the ground surface beneath the body of water to the upper surface of the water where the oil is transferred to a ship or barge used to transfer the oil and gas to a location where the oil and gas is refined into finished products. 
     The second attachment assembly  106  may accept a plurality of quick release accessories (not shown). The second attachment assembly  106  may be to receive a pipe or other conduit (not shown) that is used to receive lighter than air or seawater liquids or gasses to be pumped into a buoyancy/ballast tank  108  and/or buoyancy/ballast tank bladder  109  illustrated in  FIGS. 5 and 7 . 
     The buoyancy/ballast tank  108  and/or buoyancy/ballast tank bladder  109  are capable of being used during any of the aforementioned methods of transport of oil containment recovery dome  100 . 
     It is possible for one of the connectors  105 ,  106  described herein to be used in conjunction with adding or removing material from the bladders  109 . The connectors  105 ,  106  may also be used in conjunction with transporting oil or gas from the interior of the oil containment recovery dome  100  to a collection apparatus or vehicle. 
     The outer skin dome assembly  110  and the inner skin dome assembly  111  may each have a frame construction that includes a plurality of structural members and a plurality of hubs, which is similar to the oil containment recovery dome  100  illustrated in  FIGS. 1-8 . 
     It is possible for the outer skin dome assembly  110  and the inner skin dome assembly  111  to both have the same configuration. In certain embodiments, the outer skin dome assembly  110  may be fabricated with a generally triangular configuration, as most clearly illustrated in  FIG. 9 . In certain embodiments, the outer skin dome assembly  110  may be fabricated with a generally hexagonal/polygonal configuration, as most clearly illustrated in  FIG. 10 . 
     The outer skin dome assembly  110  and the inner skin dome assembly  111  may be interconnected by a plurality of connecting members, as most clearly illustrated in  FIG. 19 . Interconnecting the inner skin dome assembly  111  and the outer skin dome assembly  110  enhances the strength of the oil containment recovery dome  100 . 
     In certain embodiments, one of the connecting members extends between the most proximate the first attachment assembly  105 , on the outer skin dome assembly  110  and the first attachment assembly  105  on the inner skin dome assembly  111 . The first attachment assembly  105 , thereby enhancing the rigidity of the oil containment recovery dome  100 . 
     The first attachment assembly  105 , may be fabricated from the same type of materials that are used to fabricate structural members that are used to fabricate at least one of the outer skin dome assembly  110  and the inner skin dome assembly  111 . 
     A variety of techniques may be used to attach the first attachment assembly  105 , the second attachment assembly  106 , and the outer skin dome assembly  110  and the inner skin dome assembly  111 . 
     The first attachment assembly  105 , the first attachment assembly  105 , and the outer skin dome assembly  110  and the inner skin dome assembly  111  may be fabricated from a variety of materials. The materials used to fabricate these components should enable the oil containment recovery dome  100  to resist deformation when forces are applied to the oil containment recovery dome  100 . 
     Additionally, the materials used to fabricate these components should resist degradation when exposed to the extreme pressures and/or temperatures typically found where deep-water wells are drilled. The materials used to fabricate these components should also resist degradation caused by extended exposure to the materials and/or microorganisms present in the water where the oil containment recovery dome  100  is installed. 
     Examples of materials that may be used to fabricate the connecting members, the structural members, and the hubs are stainless steel, titanium, magnesium, fiberglass, and carbon fiber and fiber composites. To further reduce the potential of degradation of these components, these components may be coated with a protective material. 
     At least one of the outer skin dome assembly  110  and the inner skin dome assembly  111  may include a plurality of outer skin panels  110  that are attached to the structural members to each substantially cover the openings. Similar to the outer skin  110  and inner skin  111  used in conjunction with the oil containment recovery dome  100  illustrated in  FIGS. 1-11 , the inner skin  111  is attached to the structural members to form a water-tight seal in certain embodiments. 
     In other embodiments, a sheet of cover material is placed over a plurality of the openings on at least one of the inner surface of the inner skin dome assembly  111  or the outer surface of the outer skin dome assembly  110 . The sheet of material may be fabricated from a variety of materials using the concepts of the invention. An example of one such suitable material is non-inflated ETFE fabric. 
     To prevent damage to the cover material such as when the oil containment recovery dome  100  is being lowered into the position above the oil well, at least a portion of the openings may be covered with a temporary panel (not shown) that is fabricated from a more rigid material. An example of the rigid material is treated plywood. The oil containment recovery dome  100  may have 12″ to 18″ metal spikes attached as attachment assembly to the triangle node connections. These spikes are to ward off sea creatures, the final configuration akin to a giant sea urchin. 
     Once the oil containment recovery dome  100  is lowered into position, the temporary rigid panels may be removed. Alternatively, the rigid panels may be allowed to degrade as a result of the continued exposure to the materials and/or organisms present in the water where the oil containment recovery dome  100  is installed. 
     In the configuration of the cap section  104 , at least one outer skin panel  110  or inner skin  111  is replaced with a flexible riser boot  112  for use in accepting a feeder line  116 , as illustrated in  FIG. 6 . The riser boot  112  may have a shape that is similar to the outer skin panel  110  and inner skin panel  111  for the area penetrated by oil drilling and collection equipment (not shown). 
     The cap section  104  includes at least one, but not limited to, cap section  104  that is positionable in a closed configuration and an open configuration. When in closed configuration, the at-least-one cap section  104  substantially restricts the flow of water and/or oil through the open section  103  as illustrated in  FIGS. 2 ,  4 ,  19  and  20 . 
     When in the open configuration, the at-least-one cap section  104  substantially permits water and/or oil to pass through the open section  103 . It is also possible to position the at-least-one cap section  104  in an intermediate configuration that is between the open configuration and the closed configuration to partially restrict the flow of water and/or oil through the open section  103  located in the sphere section  101  of dome  100 . 
     The cap section  104  may be operable using a variety of methods. In one such method, cap section  104  is pivotally mounted so that cap  104  can pivot between the open configuration and the closed configuration as illustrated in  FIGS. 19 and 20 . Another possible configuration for the storage of the cap section  104  is for the at-least-one cap section  104  to be moved to an open configuration by robotic operating vehicles (“ROVs”) (not shown) and temporally moored on a space truss and staging platform  300  illustrated in  FIGS. 18 and 21 . 
     An example of one suitable technique for attaching the top section to the other portions of the oil containment recovery dome  100  is a stiffening space truss around the interface between the cap section  104  and upper sphere section. This allows the top section to open by pivot as  FIGS. 4 ,  19  and  20 . 
     In certain embodiments, the cap section  104  may be biased to a closed configuration. Installed monitoring devices in first structural beam  113  may be used to measure pressure differences between the interior and exterior of dome  100  as well as temperature, water composition and other desired data collection properties. Conduits may be used to feed these and other devices related to gas-gaseous control. 
     As an alternative to fabricating the oil containment recovery dome  100  with the structural members  113  and  114 , it is possible to use alternative systems to control the ability of water and/or oil to flow into and out of the oil containment recovery dome  100 . Such alternative systems should be capable of operating in a highly reliable manner at high pressures and/or low temperatures. An example of one such alternative system is a check valve. 
     The oil containment recovery dome  100  may include a pressure flow vent (not shown) that is capable of releasing excess pressure generated within the oil containment recovery dome  100  and thereby minimize the potential of damage of the oil containment recovery dome  100  by such excess pressure. 
     In certain embodiments, the pressure flow vent is a diaphragm check valve that is activatable in response to a specific cracking pressure within the oil containment recovery dome  100 . Flowage control by directing the leak close to the source will better enable gas venting to minimize the potential of damage of the oil containment recovery dome  100 . Similar to other embodiments discussed in this patent application, it is also possible to use louvers to release pressure from inside of the oil containment recovery dome  100  through the first attachment assembly  105  and or open section  103 . 
     Each of the cap sections  104  in the upper sphere section  101  that are defined by the first structural beams  113  and the second structural beams  114  are substantially covered with an outer skin  110  and an inner skin  111 , with structural members  113  and  114 , configured with their appropriate accessory hardware, as illustrated in  FIG. 7 . 
     A percentage of the surface of the oil containment recovery dome  100  that contains the buoyancy/ballast tanks  108  and buoyancy/ballast tank bladders  109  may be determined based upon a variety of factors. One such factor is the amount of water and/or oil that is desired to flow through the oil containment recovery dome  100  such as when lowering the oil containment recovery dome  100  from the top of the body of water to the ground surface beneath the body of water. 
     In certain embodiments, between about 25 percent and about 75 percent of the surface of the oil containment recovery dome  100  contains buoyancy/ballast tanks  108  and buoyancy/ballast tank bladders  109 . In other embodiments, between about 40 percent and about 60 percent of the surface of the oil containment recovery dome  100  is covered with the buoyancy/ballast tanks  108  and buoyancy/ballast tank bladders  109 . 
     The cylinder section  102  is positioned along and may extend substantially around the lower edge of the upper sphere section  101 , as illustrated in  FIG. 2 . The cylinder section  102  may have a height that is considerably smaller or higher than a height of the sphere section  101 . 
     While the cylinder section  102  is illustrated as being oriented in a substantially vertical orientation, it is also possible for the cylinder section  102  to have other orientations. 
     In certain embodiments, the cylinder section  102  may have a height of between about 1 foot and about 50 feet. In other embodiments, the cylinder section  102  has a height of between about 5 feet and about 100 feet. 
     The cylinder section  102  may be fabricated with at least one opening  103  that has a width and a height that are sufficiently large to permit equipment such as ROVs that are used in conjunction with drilling the oil well and/or addressing issues relating to leaks from the oil to be moved into and out of an interior region of the oil containment recovery dome  100 . 
     In certain embodiments, each of the openings  103  may have a height of between about 5 feet and about 60 feet and a width of between about 5 feet and about 60 feet. In other embodiments, the openings may have a height of about 40 feet and a width of about 80 feet. 
     It is possible for the openings to be formed with different heights and widths depending on the equipment that is to pass through the openings. In other embodiments, each of the openings is formed with a height and a width that are approximately the same. 
     In certain embodiments, a plurality of openings  103  are provided on the cylinder section  102  and such openings are positioned in a spaced-apart configuration. For example, there may be 5 to 6 openings or more in the cylinder section  102 . Using the plurality of openings enables multiple ROVs to be simultaneously used to perform work within the oil containment recovery dome  100 . 
     Open sections  103  are provided around the base of the oil containment recovery dome  100  as illustrated in  FIGS. 2 ,  4 ,  12   19 ,  26 ,  27 , and  28 . By fabricating the oil containment recovery dome  100  in this manner, it is possible for water to flow into the interior of the oil containment recovery dome  100  as the leaked oil is withdrawn from the interior of the oil containment recovery dome  100 . 
     Such a configuration allows pressure on the outside and inside of the oil containment recovery dome  100  to remain substantially the same to thereby minimize the creation of a pressure differential, which could lead to damage of the oil containment recovery dome  100 . It should be noted that the lower portion of the oil containment recovery dome structure is open to the sea (atmospheric) pressure. Approximately, up to 20% of the lower dome structure is open to sea pressure, providing the remaining upper structure available to collect the lighter-than-seawater crude oil. 
     The cylinder section  102  may be fabricated from the same materials that are used to fabricate the sphere section  101 . An example of one such configuration is a plurality of elongated members and a plurality of connectors that are attached together to form an array. 
     The angle of the base of cylinder section  102  may accommodate for different ground slope around the oil containment recovery dome  100 . To account for variations in the shape and/or orientation of the ground surface on which the oil containment recovery dome  100  is placed a buoyancy/ballast bridging ring  107 . 
     The buoyancy/ballast bridging ring  107  can span great distances to provide uniform distribution of structural loads to be dumped into the ground. The buoyancy/ballast bridging ring  107  may also be filled with ballast to assist in securing the oil containment recovery dome  100  to the ground by using mooring anchors  115  as illustrated in  FIGS. 2 and 8 . 
     While it is desirable for a lower edge of the cylinder section  102  to be positioned relatively close to the ground surface, it is generally not required for the lower edge of the cylinder section  102  to be positioned immediately adjacent to the ground surface or that a water-tight seal be formed between the lower edge of the cylinder section  102  and the ground surface. 
     In certain embodiments, a distance between the lower edge and the ground surface may be more than about 48 inches. 
     As illustrated in  FIGS. 2 and 8 , a plurality of mooring anchors  115  may be provided along the lower edge of the cylinder section  102 . The mooring anchors  115  may be positioned in a spaced-apart configuration so that the mooring anchors  115  provide support around the oil containment recovery dome  100 . 
     The mooring anchors  115  may have an adjustable height that enables the height of the mooring anchors  115  to change in response to difference in shape and orientation of the ground surface. In certain embodiments, the mooring anchors  115  may have a bias mechanism mounted therein that allows the height of the mooring anchors  115  to adjust. 
     In certain embodiments, it may be desirable to use an attachment or mounting mechanism to maintain the oil containment recovery dome  100  in a substantially stationary position with respect to the ground surface. One potential configuration is placing ballast in the buoyancy/ballast bridging ring  107  around the oil containment recovery dome  100 . 
     Another technique that may be used to restrict movement of the oil containment recovery dome  100  is a plurality of cables  117  that extend from oil containment recovery dome  100  and are attached to the ground surface, as illustrated in  FIGS. 2 ,  8 ,  26   b  and  27   a . The cables  117  may be attached at differing heights on the oil containment recovery dome  100 . 
     In operation, the oil containment recovery dome  100  may be fabricated above the surface of the body of water in which the oil containment recovery dome  100  is to be used because assembly in such conditions is typically easier than assembling the components below the water surface. In such situations, the oil containment recovery dome  100  may be transported to the location where the oil well is intended to be drilled. 
     Depending on the size of the oil containment recovery dome  100 , it may be necessary to increase buoyancy or stabilize with ballast for transport to installation site. Increased buoyancy or stabilization with ballast can be accomplished by filling buoyancy/ballast tanks  108  and buoyancy/ballast tank bladders  109  with appropriate amounts of buoyancy/ballast materials. 
     An option for transporting the oil containment recovery dome  100  is to float the oil containment recovery dome  100  to site by use of sea transport tug boats  119  such as is illustrated in  FIG. 13 . Still another option using buoyancy/ballast assist is to use helo crane, dirigibles-blimps, as illustrated in  FIG. 14 . Another option for transporting the oil containment recovery dome  100  is to place the oil containment recovery dome  100  on the surface of a heavy cargo transport ship  118  as illustrated in  FIG. 12  or use a catamaran ship  140  for transport as illustrated in  FIGS. 23 and 24 . For all cases first attachment assembly  105  may be used for transport attachments. 
     The catamaran transport ship  140  option provides a ship that includes two hulls  142  mounted in a spaced apart configuration, as illustrated in  FIGS. 23 and 24 . 
     The hulls  142  may be movable with respect to each other so that the hulls  142  can be positioned relatively close to each other while the transport ship  140  is moved to where the well is being drilled. 
     The transport ship  140  may include at least one crane  144  that is used to lift the oil containment recovery dome  100  off of the hulls  142  and then allow the oil containment recovery dome  100  to descend through the water, as illustrated in  FIG. 25 . 
     Once the area where the oil well is intended to be drilled is reached, the oil containment recovery dome  100  may be lowered through the body of water towards the ground surface beneath the body of water. An example of one such suitable technique is a dynamically positionable transport ship  140  as illustrated in  FIGS. 23 ,  24  and  25 . 
     To reduce the potential of damage to the oil containment recovery dome  100 , the oil containment recovery dome  100  may be attached to a plurality of cables  117  for lowering to the ground surface, as illustrated in  FIGS. 2 ,  23 ,  23 ,  25 ,  26   a  and  26   b . The cables  117  may not only be used to guide the ascent of the oil containment recovery dome  100  but may also be used to assist with the ascent of the oil containment recovery dome  100 . 
     As with the other forms of transport, it may be necessary to increase buoyancy or stabilize with ballast for transport to installation site. Increase buoyancy or stabilize with ballast can be accomplished by filling buoyancy/ballast tanks  108 , buoyancy/ballast tank bladders  109  and buoyancy/ballast bridging ring  107  with appropriate amounts of buoyancy/ballast materials. 
     In certain embodiments, to enhance the ability to lower the oil containment recovery dome  100  through the body of water, the cap section  104  of the oil containment recovery dome  100  may be detached from the other portions of the oil containment recovery dome  100  as the oil containment recovery dome  100  is being lowered to the ground surface beneath the body of water. 
     To increase the weight of the oil containment recovery dome  100  and thereby stabilize and increase the rate at which the oil containment recovery dome  100  can descend through the body of water, a plurality of weights may be attached to the oil containment recovery dome  100 . The weights may be configured to be released and/or emptied once the oil containment recovery dome  100  reaches the ground surface beneath the body of water. 
     To minimize the potential of a negative environmental impact from such release, materials used to fabricate the weights and/or placed inside of the weights may be indigenous to the region where the oil containment recovery dome  100  is being used. An example of one such indigenous material is sand or seawater. 
     Alternatively, the weights may be left in attachment with the oil containment recovery dome  100  to assist in retaining the oil containment recovery dome  100  in a stationary position with respect to the oil well. 
     Once the oil containment recovery dome  100  is positioned in a desired location, the equipment used to drill the oil well is then lowered from the surface of the body of water until the equipment extends through the oil containment recovery dome  100  and into the ground surface inside of the oil containment recovery dome  100 , as illustrated in  FIGS. 4 ,  18  and  19 . 
     Next, the cap section  104  may be opened by either split opened or lowered onto the oil containment recovery dome  100 , as illustrated in  FIGS. 4 ,  19 ,  20 ,  26   a ,  26   b  and  26   c . A variety of techniques may be used to attach the cap section  104  to the other portions of the oil containment recovery dome  100 . 
     After installation, the oil containment recovery dome  100  may be in a substantially closed configuration. If an oil leak develops within the oil containment recovery dome  100 , as illustrated in  FIGS. 27   a  and  27   b , the oil containment recovery dome  100  will substantially encapsulate the oil and gas leak. 
     Such encapsulation enables the leaked oil/gas to be recovered such as by extending a conduit  146  as a feed line into the interior of the oil containment recovery dome  100  through the first and second attachment assembly  105  and  106 . The oil containment recovery dome  100  thereby minimizes the escape of oil and gas thereby minimizes the potential of negative environmental impact from the escaped oil. 
     In certain configurations, it is possible to contain, hold and then withdraw sufficient oil that leaks into the oil containment recovery dome  100  so that the oil is substantially contained within the oil containment recovery dome  100  until it is possible to stop the oil well from leaking. In other configurations, it may be desirable to employ additional techniques to control the rate at which the oil is leaking and/or prevent the oil from escaping from the oil containment recovery dome  100 . 
     This process may be accomplished by selective use of the first attachment assembly  105  and the second attachment assembly  106  connected to recovery oil or gas feeder conduits and transferring recovered materials to surface equipment. Monitoring equipment may be inserted into select first attachment assembly  105  and second attachment assembly  106  to assist in locating the best attachment locations and types for the recovery equipment to be used for any given recovery condition. 
     An example of one such suitable technique that may be used in conjunction with the oil containment recovery dome  100  is to generate a heat-arc method proximate to where the oil and/or gas is leaking from the well. The method may be generated using equipment that is similar to the equipment used in conjunction with precautionary methane gas procedures from conduit  116  supplied, attachment assembly nodes  105  and  106 . 
     A methane prevention arc may cause the oil and/or gas to change into a form that is more manageable and/or is less likely to cause environmental damage. For example, the arc may sufficiently warm methane gas that leaks from the well to prevent methane crystallization. The oil containment recovery dome  100  allows such space accommodation within the double resonated dome through conduit supplied attachment assembly nodes for such equipment. 
     In another configuration, the oil containment recovery dome  100  is adapted for installation and use after the oil drilling equipment is already in place. Such an application can be done either before or after oil and/or gas is leaking from the oil well. 
     To accommodate placement after the oil drilling equipment is in place, the oil containment recovery dome  100  may include at least one movable section that creates an opening so that the oil drill equipment and or lines extending from the oil drilling equipment can pass through such as illustrated in  FIGS. 28 and 29 . 
     In one such configuration, the upper sphere section  101  of the oil containment recovery dome  100  includes a plurality of cap sections  104  that are pivotally attached to each other. When the cap sections  104  are pivoted to an open configuration, an enlarged opening is thereby defined. When the cap sections  104  are pivoted to a closed configuration, a relatively small opening with riser boots  112  may be defined through which lines extending from the oil drilling equipment can pass. 
     Depending on the configuration of the cap sections  104 , a pivoting axis may be oriented in a variety of configurations, examples of which include horizontal and vertical. The pivot hardware may attach to the first attachment assembly  105  as well as be used as temporary mooring. 
     As an alternative to pivotally attaching the cap sections  104 , it is possible to fabricate the cap sections  104  separate from each other and then attach the cap sections  104  using a fastening system. The fastening system should permit operation such as by a remotely operable vehicle (ROV). 
     The oil containment recovery dome  100  has a shape that generally conforms to at least a portion of a sphere. By increasing the portion of the sphere, the volume of the oil containment recovery dome  100  may be increased. In certain embodiments, the oil containment recovery dome  100  may be about ¾ of a sphere. 
     The oil containment recovery dome  100  should be sufficiently large to encompass the various types of equipment that could be used for drilling the oil wells. The oil containment recovery dome  100  could also be used to position and/or support a flow-through sub-sea chemical injector that is used in conjunction with the oil well. 
     Connection assemblies may be attached to the first attachment assembly  105   FIGS. 5 ,  7 ,  9 ,  10  in an upper portion of the oil containment recovery dome  100  to accommodate lines that extend between the oil-drilling platform positioned on the water surface and the oil wells. A closure mechanism (not shown) may be provided to seal off the lines and thereby restrict the ability of the oil that leaks from the oil well from escaping from the oil containment recovery dome  100 . 
     At least one of the outer skin dome assembly  110  and the inner skin dome assembly  111  may have a buoyancy/ballast bridging ring  107 , which has a configuration that is similar to the embodiment discussed with respect to  FIGS. 1-10 . The lower portion may be adjusted to account for variations on the orientation and shape of the ground surface on which the oil containment recovery dome is placed. A variety of techniques may be used to facilitate such adjustability. It is also possible to fabricate the lower portion to be self-leveling. 
     To reduce the potential of the oil containment recovery dome  100  moving with respect to the oil well drilling equipment after installation; it is possible to use a mounting mechanism that extends between the lower portion and the seabed. An example of one such suitable mounting mechanism is a plurality of mooring anchors  115  alone or in conjunction with a plurality of moors. 
     To increase the reliability of the oil containment recovery dome  100 ; it should be fabricated with minimal mechanical parts and in certain embodiments, no mechanical parts. 
     As with the other forms of transport it may be necessary to increase buoyancy or stabilize with ballast for transport to instillation site. Increase buoyancy or stabilize with ballast can be accomplished by filling buoyancy/ballast tanks  108  buoyancy/ballast tank bladders  109  and buoyancy/ballast bridging ring  107  with appropriate amounts of buoyancy/ballast materials. 
     It is also possible to fabricate the oil containment recovery dome  100  with a floatation device (not shown) attached thereto. In certain configurations, there floatation device is mounted along a lower surface of the oil containment recovery dome  100 . When the floatation device is activated, the oil containment recovery dome  100  may be moved through the water using a tow vessel such as a tugboat as illustrated in  FIG. 16 . 
     Once the oil containment recovery dome  100  arrives at the location where it is intended to be used, the floatation device may be deactivated to cause the oil containment recovery dome  100  to sink into the water. The deactivation may be accomplished at a rate that is sufficiently slow so that the descent through the water is done in a controlled manner to minimize the potential of damage to the oil containment recovery dome  100 . 
     When use of the oil containment recovery dome  100  at a particular location is completed, the floatation device may be activated to cause the oil containment recovery dome  100  to raise to the surface of the water so that the oil containment recovery dome  100  can be moved to another use location or to a storage location. 
     Because of the challenges associated with humans directly viewing the oil containment recovery dome  100 , monitoring instruments may be used in conjunction with the oil containment recovery dome  100 . Examples of the monitoring instruments include cameras, acoustic Doppler profilers, pulsed illuminator and transponders. This equipment may be mounted on attachment assemblies  105  or adjacent to the oil containment recovery dome  100 . 
     While it is generally preferable for the oil containment recovery dome  100  to be slowly lowered from the surface of the water to the ground beneath the water; it is possible that the oil containment recovery dome  100  may experience a rapid descent toward the ground beneath the water. 
     At least one line may extend between the oil containment recovery dome  100  and the crane or other device used to lower the oil containment recovery dome  100  to the ground beneath the water. If the line breaks or if the crane begins rolling out the line too quickly, the oil containment recovery dome  100  may be permitted to descent too quickly. 
     Rapid contact of the ground beneath the water by the oil containment recovery dome  100  could damage the oil containment recovery dome  100 . Such damage could impact the structural integrity of the oil containment recovery dome  100 . 
     In certain embodiments, the oil containment recovery dome  100  may include a select number of deployable buoyancy/ballast tank bladders  109  as illustrated in  FIG. 7 . A select number of deployable buoyancy/ballast tank bladders  109  may be positioned proximate within a select number of buoyancy/ballast tanks  108  of the outer skin dome assembly  110  and the inner skin dome assembly  111  so that when the buoyancy/ballast tank bladders  109  is inflated, the buoyancy/ballast tank bladders substantially fills a region between the connectors. 
     While the description is provided herein as being an buoyancy/ballast tank bladders  109 , a person of skill in the art would appreciate that this component could be broadly described as a restrainer bag that includes an outer enclosure in which a material is introduced to cause the outer enclosure to substantially fill the region between the connectors. 
     One of the buoyancy/ballast tank bladders  109  may be positioned proximate to every one of the connectors on at least one of the outer skin dome assembly  110  and the inner skin dome assembly  111 . In other embodiments, the buoyancy/ballast tank bladders  109  may be positioned in a spaced-apart configuration on the oil containment recovery dome  100 . 
     When it is sensed that the oil containment recovery dome  100  is descending more quickly than desired, the at least one buoyancy/ballast tank bladders  109  may be deployed so that the buoyancy/ballast tank bladders  109  extends substantially between at least one connector on the outer skin dome assembly  110  and at least one connector on the inner skin dome assembly  111 . 
     In certain embodiments, the deployment of the buoyancy/ballast tank bladders  109  is controlled by a manual device that is linked to the buoyancy/ballast tank bladders  109  such as by a wired or wireless connection. In another embodiment, the buoyancy/ballast tank bladders  109  may have a sensor that causes the buoyancy/ballast tank bladders  109  to automatically deploy if it is determined that the pressure change monitored by the sensor is greater than a selected amount, which is indicative of the oil containment recovery dome  100  experiencing a potentially dangerous fall. 
     The pressure exerted by the at least one buoyancy/ballast tank bladders  109  should be sufficiently large so that the connector on the outer skin dome assembly  110  resists movement with respect to the connector on the inner skin dome assembly  111 . However, the pressure exerted by the at least one buoyancy/ballast tank bladders  109  should not be too large such that the connector on the outer skin dome assembly  110  is forced away from the connector on the inner skin dome assembly  111 . Such a movement could cause damage to the oil containment recovery dome  100 . The buoyancy relief may be accomplished through the same inflation first attachment assembly  106 . 
     It is also possible to mount at least one buoyancy/ballast tank bladders  109  on an outer surface and/or a lower surface of the oil containment recovery dome  100 . The at least one buoyancy/ballast tank bladders  109  could thereby protect the oil containment recovery dome  100  from damage caused by contact with the ground beneath the water. 
     Because it is difficult to predict which side of the oil containment recovery dome  100  will make contact with the ground surface beneath the water, the buoyancy/ballast tank bladders  108  may be positioned at various locations on the outer surface and the lower surface of the oil containment recovery dome  100 . 
     The at least one buoyancy/ballast tank bladders  109  may be formed having a variety of sizes using the concepts of the invention such that the buoyancy/ballast tank bladders  108  have sufficient strength to resist damage to the oil containment recovery dome  100 . A factor that may be relevant to the size of the buoyancy/ballast tank bladders  109  is the weight of the oil containment recovery dome  100 . 
     The buoyancy/ballast tank bladders  109  may be formed with a diameter that is approximately the same as the diameter of the oil containment recovery dome  100 . In other embodiments, a plurality of buoyancy/ballast tank bladders  109  are attached together to provide a diameter that is approximately the same as the diameter of the oil containment recovery dome  100 . 
     The buoyancy/ballast tank bladders  109  may be fabricated to rapidly expand when activated. The force utilized to expand the buoyancy/ballast tank bladders  109  may be sufficiently large to compensate for the pressures typically experienced in the region where it is desired to install the oil containment recovery dome  100 . 
     Inflation of the buoyancy/ballast tank bladders  109  may be accomplished using a variety of techniques. Examples of potentially suitable techniques for inflating the buoyancy/ballast tank bladders  109  used in conjunction with the oil containment recovery dome  100  are techniques used in conjunction with inflating buoyancy/ballast tank bladders  109  used on automobiles. 
     The buoyancy/ballast tank bladders  109  may also be configured to provide additional strength to the oil containment recovery dome  100  so that the oil containment recovery dome  100  is better able to withstand damage caused by objects dropping onto the oil containment recovery dome  100 . An example of one such object that could drop onto the oil containment recovery dome  100  is the oil-drilling rig or a component thereof. 
     In another embodiment, which is illustrated in  FIG. 11 , the oil containment recovery dome  200  includes an outer sphere section  201  and cylinder section  202 . Two sphere sections  201  and a modular bay cylinder section  202  are attached to and separate the two sphere sections  201   FIG. 9 . The oil containment recovery dome  200  may be one or two half-sphere sections  201  attached to one or two half-cylinder sections  202  illustrated in  FIGS. 9 and 10 . 
     All embodiments and configurations for oil containment recovery dome  100  also be applied to oil containment recovery dome  200  as illustrated in  FIGS. 9 ,  10 ,  11 ,  15 ,  16 ,  17 ,  30  and  31  where the last two digits of the reference number are the same. 
     Oil containment recovery dome  200  is virtually the same as oil containment recovery dome  100  only in that it is generally oriented in the horizontal  FIG. 9  instead of the vertical  FIG. 2 . 
     Due to the horizontal configuration of the oil containment recovery dome  200  modular expansion cylinder sections  202  may be needed as in  FIG. 11 . These sections are treated the same as described for the oil containment recovery dome  100 . 
     Also due to the horizontal configuration of the oil containment recovery dome  200 , buoyancy/ballast bridging ring  207  may need to be elongated to accommodate the necessary added cylinder sections  202  as illustrated in  FIG. 11 . 
     Another embodiment of oil containment recovery dome  200  allows for a horizontal separation enabling the oil containment recovery dome  200  to float as a boat and encapsulate a disable or damaged ship or large surface oil spill as illustrated in  FIGS. 17 ,  30 , and  31 . It may be necessary to activate the buoyancy/ballast bridging ring  207 , buoyancy/ballast tank  208 , and buoyancy/ballast bladder system  209  for proper floatation 
     Transport and installation of the oil containment recovery dome  200  may be accomplished in the same manner described for the oil containment recovery dome  100 . 
     Another embodiment of the invention relates to an oil containment recovery dome as illustrated at  300  in  FIGS. 21 and 22  relates to a space truss and staging platform  300 . Such a configuration may facilitate the use of the oil containment recovery dome  300  on ground surfaces that are not substantially flat or which are not oriented substantially horizontal. 
     Structural beams  313  are connected using structural connector  305  laid out in a triangular grid in two horizontal paralleled plains. To the same structural connector  305 , which is the same as  106  and  206  of the oil containment recovery domes  100  and  200 , is used throughout to connect both top and bottom horizontal planes together using structural beams  314 . 
     A decking  310  may be added at appropriate locations as a covering, a staging surface, buoyancy/ballast tank  308  enclosure, buoyancy/ballast bladder  309  enclosure. 
     If buoyancy/ballast tank  308  and/or buoyancy/ballast bladder  309  are installed, they may be used in the same way as the similar structures in the oil containment recovery domes  100  and  200 . 
     The staging platform  300  may also be used as an anchoring device for dome  100  by adding ballast to the buoyancy/ballast tank  308 , and or buoyancy/ballast bladder  309  in a sufficient amount two counter the buoyancy lift from enclosed oil being recovered or other uplift forces imposed on the oil containment recovery dome  100  or staging platform  300 . 
     Another anchoring method is to apply mooring anchors  315  alone or in conjunction with ballast in a sufficient amount to counter the buoyancy lift from enclosed oil being recovered or other uplift forces imposed on the oil containment recovery dome  100  or staging platform  300 . 
     Another embodiment of the invention is illustrated in  FIGS. 30 and 31 . In this embodiment, the oil containment recovery dome is formed with a length and a width that is larger than a ship from which oil is leaking 
     The oil containment recovery dome  200  may be transported to an area where it is needed using a variety of devices such as a dirigible  220 . The oil containment recovery dome may be connected to the dirigible using at least one cable  222 . 
     When the oil containment recovery dome  200  is proximate to the ship  224  from which oil is leaking, the oil containment recovery dome  200  is lowered over the ship  224  such that a lower edge of the oil containment recovery dome  200  extends into water to a depth that is lower than the depth at which the oil is anticipated to be located, as illustrated in  FIGS. 30 and 31 . 
     A plurality of buoyancy bladders  208  may be positioned around the oil containment recovery dome  200  may retain the oil containment recovery dome  200  at a consistent depth so that objects that extend from an upper surface of the ship  224  do not contact the oil containment recovery dome  200 . 
     The oil containment recovery dome  200  thereby contains the oil there within. The contained oil may then be collected from the contained region. While it is illustrated that the oil containment recovery dome  200  remains connected to the dirigible  220 , the buoyancy bladders  208  enable the oil containment recovery dome  200  to be disconnected from the dirigible  220  during the oil recovery process.
