CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. Non-Provisional application Ser. No. 17/074,826 filed on Oct. 20, 2020, which is a continuation U.S. Non-Provisional application Ser. No. 15/908,816 filed on Mar. 1, 2018, which is a continuation of International PCT Application No. PCT/US17/55772 filed Oct. 9, 2017 and priority benefit, of U.S. Provisional Application 62/406,231 filed Oct. 10, 2016, the disclosure of which is incorporated by reference herein in its entirety. 
    
    
     BACKGROUND 
     Flexible pipe is useful in a myriad of environments, including in the oil and gas industry. Flexible pipe may be durable and operational in harsh operating conditions and can accommodate high pressures and temperatures. Flexible pipe may be bundled and arranged into one or more coils to facilitate transporting and using the pipe. 
     Coils of pipe may be positioned in an “eye to the side” or “eye to the sky” orientation. When the flexible pipe is coiled and is disposed with its interior channel facing upwards, such that the coil is in a horizontal orientation, then the coils of pipe are referred to as being in an “eye to the sky” orientation. If, instead, the flexible pipe is coiled and disposed such that the interior channel is not facing upwards, such that the coil is in an upright or vertical orientation, then the coils of pipe are referred to as being in an “eye to the side” orientation. 
     The flexible pipe may be transported as coils to various sites for deployment (also referred to as uncoiling or unspooling). Different types of devices and vehicles are currently used for loading and transporting coils of pipe, but usually extra equipment and human manual labor is also involved in the process of loading or unloading such coils for transportation and/or deployment. Such coils of pipe are often quite large and heavy. Accordingly, there exists a need for an improved method and apparatus for loading and unloading coils of pipe.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure relate generally to systems used for deploying coils of flexible pipe. The coils of pipe may be self-supported, for example, using bands to hold coils together. The coils of pipe may be self-supported, for example, using bands to hold coils together, or the coils of pipe may be supported around a reel (which may be referred to as a reel of pipe). Deployment systems according to embodiments of the present disclosure may include an installation trailer that includes a trailer frame, a lifting mechanism coupled to the trailer frame that is configured to raise or lower a coil of pipe or a reel of pipe, a braking mechanism configured to apply pressure to the pipe while the pipe is being deployed by the system, and a hydraulic power unit configured to hydraulically power the system. 
     Embodiments of the present disclosure will be described below with reference to the figures. In one aspect, embodiments disclosed herein relate to embodiments for deploying spoolable pipe from an installation trailer. 
     As used herein, the term “coupled” or “coupled to” may indicate establishing either a direct or indirect connection, and is not limited to either unless expressly referenced as such. The term “set” may refer to one or more items. Wherever possible, like or identical reference numerals are used in the figures to identify common or the same elements. The figures are not necessarily to scale and certain features and certain views of the figures may be shown exaggerated in scale for purposes of clarification. 
       FIG.  1    illustrates a block diagram of an embodiment of an installation trailer  10 . As described in detail below, the installation trailer  10  may be used to deploy spoolable pipe  12 , which may refer to any type of flexible pipe or piping capable of being bent into a coil. The spoolable pipe  12  may be wound on a spool or reel, or the spoolable pipe  12  may be handled as coils without spools or reels. Such reels or coils of spoolable pipe  12  may reduce the amount of space taken up by pipe during manufacturing, shipping, transportation, and deployment compared to rigid pipe that is not capable of being bent into a coil. 
     Pipe, as understood by those of ordinary skill, may be a tube to convey or transfer any water, gas, oil, or any type of fluid known to those skilled in the art. The spoolable pipe  12  may be made of any type of materials including without limitation plastics, metals, a combination thereof, composites (e.g., fiber reinforced composites), or other materials known in the art. The flexible pipe of the spoolable pipe  12  is used frequently in many applications, including without limitation, both onshore and offshore oil and gas applications. Flexible pipe may include Flexible Composite Pipe (FCP) or Reinforced Thermoplastic Pipe (RTP). A FCP/RTP pipe may itself be generally composed of several layers. In one or more embodiments, a flexible pipe may include a high-density polyethylene (“HDPE”) pipe having a reinforcement layer and an HDPE outer cover layer. Thus, flexible pipe may include different layers that may be made of a variety of materials and also may be treated for corrosion resistance. For example, in one or more embodiments, pipe used to make up a coil of pipe may have a corrosion protection shield layer that is disposed over another layer of steel reinforcement. In this steel-reinforced layer, helically wound steel strips may be placed over a liner made of thermoplastic pipe. Flexible pipe may be designed to handle a variety of pressures. Further, flexible pipe may offer unique features and benefits versus steel/carbon steel pipe lines in the area of corrosion resistance, flexibility, installation speed and re-usability. 
     The installation trailer  10  of  FIG.  1    includes a trailer frame  14  that provides a base and support for other components of the installation trailer  10 , such as a lifting mechanism  16  coupled to the trailer frame  14 . The trailer frame  14  may be constructed of one or more structural components, such as, but not limited to, beams, columns, posts, tubes, sheets, and so forth, coupled to one another via various techniques, such as, but not limited to, bolts, screws, welds, brazing, and so forth. The trailer frame  14  may be made from steel or other metal alloys. The lifting mechanism  16  may be configured to raise or lower a coil of spoolable pipe  12  or a reel of spoolable pipe  12 , as described in detail below. The installation trailer  10  may also include a braking mechanism  18  configured to apply pressure (to create back tension) to the spoolable pipe  12  while the spoolable pipe  12  is being deployed by the installation trailer  10 , as described in detail below. Finally, the installation trailer  10  may include a hydraulic power unit  20  configured to hydraulically power the installation trailer  10 . The hydraulic power unit  20  may be coupled to the trailer frame  14  or disposed on a separate skid in certain embodiments. The installation trailer  10  may include two or more wheels  22  to enable the installation trailer  10  to be moved. The wheels  22  may be tires or continuous tracks to accommodate movement on different types of terrain. Further, certain embodiments may include appropriate wheels  22  to enable the installation trailer  10  be towed along roadways on the wheels  22 . 
       FIG.  2    illustrates a perspective view of an embodiment of a coil  30  of spoolable pipe  12 . The coil  30  may be defined by an axial axis or direction  32 , a radial axis or direction  34 , and a circumferential axis or direction  36 . The coil  30  may be formed by wrapping the spoolable pipe  12  into a coil with an interior channel  38  formed axially  32  therethrough, where the coil  30  may be moved as a single package or bundle of coiled pipe, as shown in  FIG.  2   . Each complete turn of coiled pipe may be referred to as a wrap of pipe. Multiple wraps of pipe in the coil  30  may be configured in columns along the axial direction  32  of the coil  30  and/or configured in layers along the radial direction  34  of the coil  30 . For example, multiple columns of wraps may be formed along the axial direction  32  of the coil  30 , where an axial dimension  40  of the coil  30  is based on the diameter of the pipe  12  and the number and axial  32  position of wraps forming the coil  30 . Further, multiple layers of wraps may be formed along the radial direction  34  of the coil  30 , where a radial dimension  42  of the coil  30  is based on the diameter of the pipe and the number and radial  34  position of the wraps forming the coil  30 . In certain embodiments, a weight of the coil  30  may exceed 40,000 pounds (18,144 kilograms). As such, the trailer frame  14  and other components of embodiments of the installation trailer  10  may be configured to handle such coils  30  that other trailers not having the features of the installation trailer  10  cannot. For example, the structural members  80  of embodiments of the installation trailer  10  may be larger or heavier than ones used in other trailers. In one or more embodiments, the coil  30  may be disposed on a reel, which is further discussed below in  FIG.  3   . 
     As shown in  FIG.  2   , the coil  30  of spoolable pipe  12  may be one or more layers (e.g., layers  44  and  46 ) of pipe packaged or bundled into the coil  30 . The coil  30  may include at least one or more layers of pipe that have been coiled into a particular shape or arrangement. As shown in  FIG.  2   , the coil  30  is coiled into a substantially cylindrical shape having substantially circular bases  48  and  50  formed on each end of the coil  30 , where the axial dimension  40  of the coil  30  is measured between the two bases  48  and  50 . 
     As known to those of ordinary skill in the art, the spoolable pipe  12  used to make up the coil  30  shown in  FIG.  2    may be coiled using spoolers or other coiler machines suited for such a function. Those of ordinary skill will recognize that the present disclosure is not limited to any particular form of coiler or other device that may be used to form pipe into a coil. Coiling pipe into a coil of pipe, such as  30 , assists when transporting pipe, which may be several hundred feet in length in one or more embodiments. Further, the coil  30  may be assembled as a coil to facilitate deployment of the coil. Deployment, as described above and used herein, may refer to the action of unspooling or unwinding the spoolable pipe  12  from the coil  30 . 
     After being assembled into a coil, the coil  30  shown in  FIG.  2    may include the interior channel  38  formed axially  32  through the coil  30 . The interior channel  38  is a bore disposed generally in the center of the coil  30 . The interior channel  38  is substantially circular-shaped. The coil  30  may have an outer diameter (OD) and an inner diameter (ID), where the inner diameter is defined by the interior channel  38 . As shown in  FIG.  2   , one or more bands  52  may be wrapped around the coil  30  to help prevent the coil  30  from unraveling. When the spoolable pipe  12  is deployed, the bands  52  may be cut at one or more desired locations, as described in detail below. 
       FIG.  3    illustrates a perspective view of an embodiment of a reel  60  of spoolable pipe  12 . In many instances, the coil  30  of spoolable pipe  12  may be wound around the components of the reel  60 , instead of transported as a bundled, freestanding package (e.g., as shown in  FIG.  2   ). The coil  30  may be wound around the reel  60  such that the interior channel of the coil  30  is concentric with a central bore of the reel  60 . A reel, as understood by those of ordinary skill, may include a cylindrical drum, such as cylindrical drum  62 , around which layers of pipe may be wrapped to form the coil  30 . The reel  60  may include two substantially circular reel ends  64  and  66  that are capable of turning about a shared axis. Accordingly, the reel ends  64  and  66  may be attached to the cylindrical drum  62 . 
     As shown in  FIG.  3   , a bore  68  is disposed in each end  64  and  66  at a substantially central position. In addition, the bores  68  for each end  64  and  66  are substantially aligned with each other (and may also be aligned with a central axis of cylindrical drum  62 ). Spoolable pipe  12  (e.g. flexible pipe) may be wound around the cylindrical drum  62  using any means known to those of ordinary skill in the art. 
       FIG.  4    illustrates a perspective view of an embodiment of the installation trailer  10 , which may have a front side  70  and a rear side  72 . In the illustrated embodiment, the trailer frame  14  is made from several structural members  80  coupled to one another such that the trailer frame  14  may support the other components of the installation trailer  10  and the weight of the coil  30  or reel  60 , which may exceed 40,000 pounds (18,144 kilograms). For example, the structural members  80  may be made from square steel tubing or steel I-beams. The trailer frame  14  may include a trailer connection point  82 , which may be a hitch, such as a draw bar hitch. A draw bar hitch may be a type of tow hitch that includes a ball extending from a bar and configured to secure a hook or a socket combination for the purpose of towing or being towed. Those of ordinary skill in the art will appreciate that other types of tow hitches and attachment systems may be used to attach another vehicle to the installation trailer  10 . 
     Accordingly, a vehicle (not shown) may be fitted with a connector or attachment system known to those of ordinary skill in the art for connecting to the installation trailer  10 . In one or more embodiments, a vehicle used to tow the installation trailer  10  may include without limitation, a dozer, a front-end loader, or excavator, for example, when the installation trailer  10  is fully loaded with the coil  30  or reel  60 , or by standard trucks, automobiles, or other vehicles, for example, when the installation trailer  10  is in an unloaded state (i.e. is not carrying the coil  30  or reel  60 ). The installation trailer  10  may be further designed for off-road use, such that the wheels  22  coupled to the trailer frame  14  are also designed for off-road use. In some embodiments, the wheels  22  may be wide base tires (e.g., super single tires) coupled to heavy duty hubs. Thus, the installation trailer  10  may be adapted for use with many types of roads and terrains. In certain embodiments, the installation trailer  10  is capable of deploying the spoolable pipe  12  by means of towing the installation trailer  10  along a pipeline path or keeping the installation trailer  10  stationary and pulling the spoolable pipe  12  off the installation trailer  10 . 
     As shown in  FIG.  4   , the lifting mechanism  16  may be used to raise and lower coils  30  or reels  60  with the use of two pairs of “j-shaped” hooks. A lower set of hooks  84  can lift coils  30  or reels  60  with a first range of diameters (e.g., between approximately 12 to 13.5 feet) and an upper set of hooks  86  can lift coils  30  or reels  60  with a second range of diameters (e.g., between approximately 13.6 to 16 feet) that is greater than the first range. The two sets of lifting hooks  84  and  86  may be mechanically connected to one another and may be raised and lowered by use of hydraulic cylinders capable of lifting or lowering coils  30  or reels  60  that may exceed 40,000 pounds (18,144 kilograms). 
     In the illustrated embodiment, the braking mechanism  18  may be configured as a pipe brake that applies pressure to the spoolable pipe  12  perpendicular to the helical wrapping of the spoolable pipe  12 . For example, the braking mechanism  18  may include a pipe-contacting component  88  coupled to support components  90 . The pipe-contacting components  88  may be a solid or hollow beam, pipe, tube, or column. In certain embodiments, the pipe-contacting component  88  may be in two parts to help maintain contact with the spoolable pipe  12  as each layer is being deployed, as described in detail below. 
     In the illustrated embodiment, the hydraulic power unit  20  may be coupled to the trailer frame  14  near the trailer connection point  82 . For example, the hydraulic power unit  20  may include an electric-start gasoline or diesel engine, 2-stage hydraulic pump, hydraulic fluid reservoir, and gasoline reservoir configured to provide hydraulic power to the hydraulic components of the installation trailer  10 , such as the hydraulic cylinders of the lifting mechanism  14  or other hydraulic cylinders described below. 
     As shown in  FIG.  4   , the installation trailer  10  may include a coil containment cage  92  that may be made from several structural members  94  coupled to one another. For example, the structural members  94  may be made from square steel tubing. As described in detail below, the coil containment cage  92  may be used to block undesired movement of coils  30  of spoolable pipe  12 , such as movement in the axial  32  direction outside the coil containment cage  92 . In other words, the coil containment cage  92  provides side containment of the coils  30 . Since the circular reel ends  64  and  66  of the reel  60  provide a similar function, the coil containment cage  92  may be omitted when the installation trailer  10  is used for deploying reels  60 . In certain embodiments, one or more rollers  96  may be coupled to the coil containment cage  92  to reduce friction or possible damage to the outer surface of the spoolable pipe  12  when the spoolable pipe  12  contacts the coil containment cage  92 . 
       FIG.  5    illustrates a perspective exploded view of an embodiment of the installation trailer  10  to better show how the components of the installation trailer  10  may be coupled to one another in certain embodiments. In particular, the braking mechanism  18  may include one or more braking posts  110  that fit into one or more corresponding trailer frame braking posts  112 . Similarly, the coil containment cage  92  may include one or more cage posts  114  that fit into one or more corresponding trailer frame cage posts  116 . Thus, the modular and interchangeable design of the illustrated embodiment of the installation trailer  10  enables the functionality of the installation trailer  10  to be easily modified depending on the needs of a particular deployment. For example, different types of braking mechanisms  18  may be used or the coil containment cage  92  omitted when deploying reels  60 . The posts  110 ,  112 ,  114 , and  116  may be various types of hollow or solid posts, beams, columns, or stands coupled to each other using various fastening techniques, such as bolts, screws, pins, and so forth. In further embodiments where modularity or interchangeability is not used, the components of the installation trailer  10  may be coupled to one another via welding, brazing, or similar techniques. 
       FIG.  6    illustrates a top view of a portion of an embodiment of the installation trailer  10 . In the illustrated embodiment, the trailer frame  14  includes a first rear structural member  130  coupled to a rear cross-member  132  via a first hinge  134  and a second rear structural member  136  coupled to the rear cross-member  132  via a second hinge  138 . The first and second hinges  134  and  138  enable the trailer frame  14  to be collapsible such that a collapsed system width  140  is less than an expanded system width  142 . In other words, the first and second hinges  134  and  138  enable the first and second rear structural members  130  and  136  to fold inward (e.g., collapsed configuration). As such, the wheels  22  do not extend beyond the collapsed system width  140  when the trailer frame  14  is in the collapsed configuration. In  FIG.  6   , the first rear structural member  130  is shown collapsed and the second rear structural member  136  is shown expanded. The collapsed system width  140  of the collapsed configuration may reduce transportation requirements associated with shipping the installation trailer  10 . A hinge pin may be inserted into corresponding hinge openings  140  in the first and second hinges  134  and  138  and first and second rear structural members  130  and  136  to maintain the installation trailer  10  in the collapsed configuration or an expanded configuration (e.g., with the expanded system width  142 ). Other techniques may also be used to facilitate collapsing the installation trailer  10  as discussed below. 
       FIG.  7    illustrates a perspective view of a portion of an embodiment of the installation trailer  10 . In the illustrated embodiment, the braking mechanism  18  includes the pipe-contacting component  88  coupled to the support components  90 . As shown in  FIG.  7   , the pipe-contacting component  88  includes a first pipe brake tube  160  coupled to one or more first pipe brake arms  162  and a second pipe brake tube  164  coupled to one or more second pipe brake arms  166 . The first and second pipe brake arms  162  and  166  may fit within corresponding brake arm sockets  168  of the support components  90 . The first and second pipe brake arms  162  and  166  may extend outward from the brake arm sockets  168  hydraulically (e.g., using the hydraulic power unit  20 ) or manually to contact the first and second pipe brake tubes  160  and  164  against the spoolable pipe  12  as it is being deployed. Thus, the braking mechanism  18  applies pressure to the spoolable pipe  12  and helps prevent undesired unspooling, free-spooling, or backlash of the spoolable pipe  12 . In addition, by providing two pipe brake tubes  160  and  164 , the braking mechanism  18  may be able to provide pressure axially  32  across the axial dimension  40  as the spoolable pipe  12  deploys. In other words, as a layer of spoolable pipe  12  deploys, the first portion of the axial dimension  40  where the spoolable pipe  12  has been deployed will have a smaller radial dimension  42  than a second portion of the axial dimension  40  where the spoolable pipe  12  has not been deployed. Thus, the first pipe brake tube  160  may extend further out of the brake arm sockets  168  to contact the first portion of the axial dimension  40  than the second pipe brake tube  164  contacting the second portion of the axial dimension  40 . In further embodiments, the pipe-contacting component  88  may include more than two pipe brake tubes or the pipe-contacting component  88  may be configured as a single pipe brake tube. 
     In certain embodiments, one or more band cutters  170  may be attached to the pipe brake tubes  160  and  164 , brake arms  162  and  166 , brake arm sockets  168 , or other portions of the braking mechanism  18 . The band cutters  170  may include a cutting portion  172  that is sharpened to be able to cut through the bands  52 . By coupling the band cutters  170  to the pipe brake tubes  160  and  164  or brake arms  162  and  166 , the band cutters  170  may be in position to cut through the bands  52  because the pipe brake tubes  160  and  164  are in contact with the outer layer or layers of the coil  30 . In certain embodiments, the band cutters  170  may be made from multiple components to enable the cutting portion  172  to be removed or replaced. In further embodiments, the band cutters  170  may be omitted and other techniques (e.g., manual band cutting) used to cut the bands  52 . In general, the embodiments of the braking mechanism  18  and band cutters  170  shown in  FIG.  7    may be used with any of the embodiments of the installation trailer  10  described herein. 
       FIG.  8    illustrates a perspective view of an embodiment of the installation trailer  10  having a re-rounding mechanism  190  configured to re-round the deploying spoolable pipe  12 . In the illustrated embodiment, the re-rounding mechanism  190  is coupled to structural members  80  of the trailer frame  14  via one or more re-rounding supports  192 , which may be made from square steel tubing or steel I-beams, for example. In certain embodiments, the spoolable pipe  12  may have an oval cross-sectional shape when coiled. In other words, the spoolable pipe  12  may not have a circular cross-sectional shape. Embodiments of the re-rounding mechanism  190  may use rollers or other components with circular or partially-circular shapes to re-shape the spoolable pipe  12  to have a circular or substantially circular cross-sectional shape when the rollers or other components are engaged with or pressed against the spoolable pipe  12 . For example, the re-rounding mechanism  190  may include one or more pairs of rollers located approximately 180 degrees apart from one another that engage with an outer surface of the spoolable pipe  12 . Other types of re-rounding mechanisms  190  and re-rounding techniques may also be used. For example, the re-rounding mechanisms  190  may use a clamp or other device to push against some or all of the outer surface of the spoolable pipe  12 . In certain embodiments, the re-rounding mechanisms  190  may be configured to move axially  32  back and forth along the re-rounding support  192  as the spoolable pipe  12  deploys or the re-rounding mechanisms  190  may be configured to tilt or pivot in other ways to correspond to the orientation of the deploying spoolable pipe  12  and reduce any undesired forces exerted on the spoolable pipe  12 . In general, the embodiment of the re-rounding mechanism  190  shown in  FIG.  8    may be used with any of the embodiments of the installation trailer  10  described herein. 
       FIG.  9    illustrates a side view of an embodiment of the installation trailer  10  with the coil  30  of the spoolable pipe  12  disposed about a drum assembly  210  that may be used to handle the coil  30  in a similar manner to the reel  60 . However, use of the drum assembly  210  provides certain benefits over handling reels  60  of spoolable pipe  12 . For example, one drum assembly  210  may be used to handle many coils  30  without the logistics associated with empty reels or spools. In addition, use of the drum assembly  10  enables heavier coils  30  of spoolable pipe  12  to be handled and transported because the weight of the reels  60  is not involved. In the illustrated embodiment, the drum assembly  210  includes a support bar  212 , expandable spokes  214 , drum segments  216 , and spoke frames  218 . The support bar  212  may be used to handle the drum assembly  10  and provide support for the various components of the drum assembly  210 . The expandable spokes  214  may move between retracted and extended positions to enable the drum assembly  210  to be inserted or removed from the coil  30 . The drum segments  216  may have a semi-circular shape to correspond to the semi-circular shape of the interior channel  38 . When the drum assembly  210  is in the extended position, the drum segments  216  may contact the coil  30  with enough pressure on the interior channel  38  such that the coil  30  is secured to the drum assembly  210 . The spoke frames  218  may be used to provide cross-support to the expandable spokes  214 . As shown in  FIG.  9   , the support bar  212  may fit in either the lower or upper set of hooks  84  and  86  depending on an overall diameter of the coil  30 . In further embodiments, other types of drum assemblies  210  may be used to deploy coils  30  using the installation trailer  10 . In addition, the embodiment of the drum assembly  210  shown in  FIG.  9    may be used with any of the embodiments of the installation trailer  10  described herein. 
     The side view of  FIG.  9    also provides another perspective of some of the features of the installation trailer  10  discussed above. For example, the braking mechanism  18  is shown proximate the outermost layer of the coil  30 , thereby providing pressure (or back tension) to the deploying spoolable pipe  12 . In certain embodiments, the braking mechanism  18  may include one or brake stops  220  to help prevent the braking mechanism  18  from contacting the drum assembly  210 , such as when all the spoolable pipe  12  has been deployed from the drum assembly  210 . In certain embodiments, the brake stop  220  may be a pin that is inserted into the pipe brake arm  162  to prevent the pipe-contacting component  88  from traveling far enough to contact the drum assembly  210 . The pin of the brake stop  220  may be inserted into different positions along the pipe brake arm  162  depending on the diameter of the drum assembly  210 . In other embodiments, the brake stop  220  may be configured hydraulically or electrically to limit the travel of the pipe-contacting component  88  in a similar manner. In addition, the coil  30  is shown disposed within the coil containment cage  92 . 
       FIG.  10    illustrates a side view of an embodiment of the installation trailer  10  with the reel  60  of the spoolable pipe  12 . In the illustrated embodiment, a reel axle  230  has been inserted into the bore  68  of the reel  60  to enable the installation trailer  10  to deploy the spoolable pipe  12  from the reel  60 . The reel axle  230  may be a solid cylinder of steel or similar metal capable of supporting the weight of the reel  60 . Reel axle bushings or other types of bearings may be provided on the ends of the reel axle  230  or the bore  68  to reduce friction during rotation of the reel  60  during deployment of the spoolable pipe  12 . The reel axle bushings may be secured by pins or similar devices. As shown in  FIG.  10   , the reel axle  230  may fit in either the lower or upper set of hooks  84  and  86  depending on an overall diameter of the reel  60 . The braking mechanism  18  is shown proximate the outermost layer of the reel  60 , thereby providing pressure to the deploying spoolable pipe  12 . In certain embodiments, the braking mechanism  18  may also include brake stops  220  to help prevent the braking mechanism  18  from contacting the cylindrical drum  62 , such as when all the spoolable pipe  12  has been deployed from the reel  60 . As shown in  FIG.  10   , the coil containment cage  92  may not be used when deploying reels  60 . Thus, embodiments of the installation trailer  10  may be used to deploy either coils  30  or reels  60 , which may not be true of other trailers that lack the features of the installation trailer  10 . 
       FIG.  11    illustrates a perspective view of another embodiment of the installation trailer  10  in an expanded configuration. The illustrated embodiment of the installation trailer  10  includes several components described in detail above. For example, the installation trailer  10  includes the trailer frame  14 , which may include a rear gate  238 . The rear gate  238  may be opened to enable coils  30  or reels  60  to be inserted into the installation trailer  10 . For example, the installation trailer  10  may be moved toward a stationary coil  30  or reel  60 , which may then be coupled to the lifting mechanism  16 , and the rear gate  238  closed prior to deployment. The rear gate  238  provides additional support and stability to the trailer frame  14  when the rear gate  238  is closed. In addition, the rear gate  238  may provide an additional support point for the spoolable pipe  12  as it deploys from the installation trailer  10 . For example, the spoolable pipe  12  may rest on a lower or upper horizontal beam of the rear gate  238  during deployment. The trailer frame  14  may also include ladders  240  or platforms  242  for personnel access. Further, the trailer frame  14  may be collapsible, as described in detail below. As shown in  FIG.  11   , the installation trailer  10  has the expanded system width  142 . 
     The embodiment of the installation trailer  10  shown in  FIG.  11    may also include the lifting mechanism  16 , which is configured to move coils  30  or reels  60  at an angle  244  with respect to the trailer frame  14 . In particular, the lifting mechanism  16  may include an axle coupler  246  that moves along an inclined lifting beam  248 , which may be accomplished manually, electrically, or hydraulically. Moving coils  30  or reels  60  at the angle  244  may reduce the amount of force compared to movement straight up or down. In  FIG.  11   , the braking mechanism  18  may include a caliper brake  250  that includes one or more calipers  252  disposed against a rotor  254 , which may be coupled to the lifting mechanism  16 . The caliper brake  250  may be used to slow or stop rotation of the coil  30  or reel  60  during deployment, thereby helping to prevent undesired unspooling, free-spooling, or backlash of the spoolable pipe  12 . In general, the embodiment of the caliper brake  250  shown in  FIG.  11    may be used with any of the embodiments of the installation trailer  10  described herein. Further, the braking mechanism  18  may include the pipe-contacting component  88  and support components  90  described above. The installation trailer  10  may also include the hydraulic power unit  20  disposed near the front side  70 . In addition, the installation trailer may include wheels  22  disposed near the rear side  72 . In the illustrated embodiment, the two wheels  22  on each side may be coupled to a frame  256  that tilts about a pivot  258  to enable the installation trailer  10  to move easily over uneven terrain. 
     The installation trailer  10  shown in  FIG.  11    may be used to handle both coils  30  and reels  60 . When deploying coils  30 , containment flanges  260  may be used in a similar manner to the coil containment cage  92  described above. For example, the containment flanges  260  may serve a similar function as the reel ends  64  and  66  of the reel  60 . In other words, the containment flanges  260  may block undesired movement of coils  30  of spoolable pipe  12 , such as movement in the axial  32  direction outside the containment flanges  260  (e.g., side containment). As shown in  FIG.  11   , the containment flanges  260  may be coupled to the lifting mechanism  16 . When the installation trailer  10  is used to deploy reels  60 , the containment flanges  260  may be moved axially  32  to accommodate the reels  60 . In other words, the two containment flanges  260  may be moved apart from one another to create additional space between the containment flanges  260 . This feature may also be used to accommodate coils  30  with different axial dimensions  40 . In other words, the two containment flanges  260  may be moved closer to one another for coils  30  with smaller axial dimensions  40  to adequately block undesired movement of the coils  30  outside the containment flanges  260 . In general, the embodiment of the containment flanges  260  shown in  FIG.  11    may be used with any of the embodiments of the installation trailer  10  described herein. 
       FIG.  12    illustrates a perspective view of an embodiment of the installation trailer  10  in a collapsed configuration, such that the collapsed system width  140  is less than the expanded system width  142  shown in  FIG.  11   . Certain features of the lifting mechanism  16  and braking mechanism  18  have been removed for clarity. The installation trailer  10  includes one or more hinges  270  that enable the installation trailer  10  to be collapsed and expanded. For example, the hinges  270  may allow structural members  80  of the trailer frame  14  to move toward each other. Additional hinges  270  (not shown) may be located near the front side  70  or in other locations to facilitate collapse of the installation trailer  10 . In addition, the rear gate  238  may be configured to fold down as shown in  FIG.  12   . 
       FIG.  13    illustrates a perspective view of a portion of an embodiment of the installation trailer  10 . In the illustrated embodiment, each of the containment flanges  260  may be made from a first flange component  280  coupled to a second flange component  282  via a flange hinge  284 . Thus, the containment flanges  260  may be folded upon themselves to reduce the overall size of the containment flanges  260 , such as during transport or shipping. Such embodiments of the containment flanges  260  may also be referred to as truncated containment flanges  260 . For example, after the containment flanges  260  are folded, the containment flanges  260  may be rotated circumferentially  36  to have the flange hinges  284  pointing upwards, thereby reducing a height  286  of the installation trailer  10  when in the collapsed configuration. In addition,  FIG.  13    shows the rear gate  238  in an open position, such as when coils  30  or reels  60  are inserted into the installation trailer  10 . 
       FIG.  14    illustrates a perspective view of another embodiment of the installation trailer  10  in an expanded configuration. The illustrated embodiment of the installation trailer  10  includes several components described in detail above. For example, the lifting mechanism  16  includes the axle coupler  246  and inclined lifting beam  248 . In addition, the lifting mechanism  16  may include a hydraulic cylinder  300  coupled to the axle coupler  246  via a lifting extension  302 . The hydraulic cylinder  300  may be used to move the axle coupler  246  along the inclined lifting beam  248  to move coils  30  or reels  60  up or down. The lifting extension  302  may be a belt, chain, or similar device to effectively extend the reach of the hydraulic cylinder  300 . One or both of the hydraulic cylinder  300  and axle coupler  246  may include rollers  304  to enable the lifting extension  302  to at least partially rotate about the rollers  304 . In certain embodiments, a track or rail  306  may be formed in the inclined lifting beam  248  to enable the axle coupler  246  to securely move along the inclined lifting beam  248 . In other embodiments, the lifting extension  302  may be omitted or other techniques used to move the axle coupler  246  along the inclined lifting beam  248 . 
     In the illustrated embodiment of  FIG.  14   , the containment flanges  260  may be configured differently than that shown in  FIG.  13   . Specifically, the containment flanges  260  may include one or more containment flange extensions  308  configured to extend radially  34  out from the containment flanges  260 . For example, each containment flange  260  may have two fixed portions  310  that extend in first and second circumferential  36  directions spaced approximately 90 degrees apart from one another and two containment flange extensions  308  that extend in third and fourth circumferential  36  directions spaced approximately 90 degrees apart from one another. Thus, the fixed portions  310  and containment flange extensions  308  together provide containment evenly about the containment flanges  260 . Further, retraction of the containment flange extensions  308  reduces the overall dimensions of the containment flanges  260  and the installation trailer  10 , which may be useful when the installation trailer  10  is shipped or transported. The containment flange extensions  308  may be extended manually or hydraulically. In certain embodiments, the containment flanges  260  include drive sections  312 , which may be configured to engage with the support bar  212  of the drum assembly  210  or the reel axle  230  of the reel  60 . As shown in  FIG.  14   , the drive sections  312  may include an opening  314  with a shape complementary to that of the support bar  212  or the reel axle  230  such that rotation of the support bar  212  or the reel axle  230  causes rotation of the containment flanges  260 . For example, the opening  314  may have a generally rectangular shape to engage with a generally square or rectangular cross-sectional shape of the support bar  212  or the reel axle  230 . In general, the embodiment of the containment flanges  260  shown in  FIG.  14    may be used with any of the embodiments of the installation trailer  10  described herein. 
       FIG.  15    illustrates a perspective view of the embodiment of the installation trailer  10  shown in  FIG.  14   , but from the front side  70 . In the illustrated embodiment, four hinges  270  are located near the front side  70 , which may enable a front section  330  of the installation trailer  10  to move perpendicular to the axial  32  direction (e.g., toward or away from the front side  70 ). In other words, when the hinges  270  are extended (e.g., approximately parallel to the axial  32  direction), the front section  330  may be extended toward the front side  70 , which also extends the side structural members  80  outwards (e.g., axially  32 ) so the installation trailer  10  is at the expanded system width  142  and a length  332  of the installation trailer  10  is also increased. When the hinges  270  are retracted (e.g., approximately perpendicular to the axial  32  direction), the front section  330  may be retracted toward the rear side  72 , which also retracts the side structural members  80  inward, as described in detail below. 
       FIG.  16    illustrates a side view of the embodiment of the installation trailer  10  shown in  FIGS.  14  and  15   . In the illustrated embodiment, the angle  244  of the inclined lifting beam  248  is shown with respect to the horizontal portion of the trailer frame  14 . Thus, the lifting mechanism  16  is used to move the coil  30  or reel  60  along the angle  244 , which also adjusts the height of the coil  30  or reel  60  above the surface that the installation trailer  10  is on. Further, the illustrated embodiment shows the use of the drum assembly  210  to handle the coil  30 . In other embodiments, reels  60  may be handled in a similar manner as discussed above. The illustrated embodiment also shows how the containment flanges  260  provide containment across the diameter of the coil  30  via the use of the containment flange extensions  308  and the fixed portions  310 . Finally,  FIG.  16    shows the height  286  and length  332  of the installation trailer  10  in the expanded configuration. 
       FIG.  17    is a top view of the embodiment of the installation trailer  10  shown in  FIGS.  14 - 16   . In the illustrated embodiment, the front section  330  is located extended toward the front side  70  since the installation trailer  10  is in the expanded configuration. Accordingly, the installation trailer  10  is shown with the expanded system width  142 . Other aspects of the installation trailer  10  are described above. 
       FIG.  18    illustrates a rear view of the embodiment of the installation trailer  10  shown in  FIGS.  14 - 17   . In the illustrated embodiment, the coil  30  is shown with the axial dimension  40  and the installation trailer  10  is shown with containment flange width  350 . In certain embodiments, the containment flanges  260  may be adjustable axially  32  to accommodate coils  30  with different axial dimensions  40 . In other words, the containment flanges  260  may be moved inward toward each other so that the containment flange width  350  is substantially the same as the axial dimension  40  of the coil  30 , which may reduce the potential for the spoolable pipe  12  to move outside of the axial dimension  40 . In certain embodiments, one or more containment posts  352  may be coupled to containment flanges  260  to enable the containment flanges  260  to move axially  32 . In other words, the containment posts  352  may extend outward from the lifting mechanism  16  when the containment flanges  260  are retracted away from the coil  30  and the containment posts  352  may not extend outward or extend less from the lifting mechanism  16  when the containment flanges  260  are extended against the coil  30 . The containment posts  352  may be circular steel posts or similar columns or beams configured to extend through openings formed in the lifting mechanism  16 . Other aspects of the installation trailer  10  are described above. 
       FIG.  19    illustrates a front view of the embodiment of the installation trailer  10  shown in  FIGS.  14 - 18   . In the illustrated embodiment, the hinges  270  are shown in more detail. For example, the hinges  270  on the front section  330  may be coupled to hinges  270  on the side structural members  80  by leaves  370 . Thus, the leaves  370  are generally aligned with the axial axis  32  when the installation trailer  10  is in the extended configuration. Other aspects of the installation trailer  10  are described above. 
       FIG.  20    illustrates a perspective view of the embodiment of the installation trailer  10  shown in  FIGS.  14 - 19    in the collapsed configuration. In the illustrated embodiment, the side structural members  80  have moved in toward one another via the hinges  270  so that the installation trailer  10  has the collapsed system width  140 . In addition, the containment flange extensions  308  have been retracted into the containment flanges  260  and the containment flanges  260  rotated circumferentially  36  to reduce the height  286  of the installation trailer  10 , thereby reducing the size and associated costs and logistics associated with shipping or transporting the installation trailer  10 . In addition, the leaves  370  have folded inward to be approximately perpendicular to the axial axis  32 , thereby moving the front section  330  toward the rear side  72  and reducing the length  332  of the installation trailer  10 . 
       FIG.  21    illustrates a perspective view of the embodiment of the installation trailer  10  shown in  FIG.  20   , but from the front side  70 . Again, the leaves  370  are shown folded inward to be approximately perpendicular to the axial axis  32 , thereby moving the front section  330  toward the rear side  72  and reducing the length  332  of the installation trailer  10 . Other aspects of the installation trailer  10  are described above. 
       FIG.  22    illustrates a side view of the embodiment of the installation trailer  10  shown in  FIGS.  20  and  21   . In the illustrated embodiment, the containment flanges  260  are rotated circumferentially  36  to reduce the diameter of the containment flanges  260 , thereby reducing the height  286  of the installation trailer  10  in the retracted configuration. In addition, the front section  330  is moved toward the rear side  72 , thereby reducing the length  332  of the installation trailer  10 . 
       FIG.  23    is a top view of the embodiment of the installation trailer  10  shown in  FIGS.  20 - 22   . In the illustrated embodiment, the front section  330  is located retracted away from the front side  70  (e.g., toward the rear side  72 ) since the installation trailer  10  is in the collapsed configuration. Accordingly, the installation trailer  10  is shown with the collapsed system width  140 . Other aspects of the installation trailer  10  are described above. 
       FIG.  24    illustrates a rear view of the embodiment of the installation trailer  10  shown in  FIGS.  20 - 23   . As shown in  FIG.  24   , the installation trailer  10  has the collapsed system width  140 . Other aspects of the installation trailer  10  are described above. 
       FIG.  25    illustrates a front view of the embodiment of the installation trailer  10  shown in  FIGS.  20 - 24   . In the illustrated embodiment, the leaves  370  are approximately perpendicular with the axial axis  32 , thereby enabling the installation trailer  10  to have collapsed system width  140 . Other aspects of the installation trailer  10  are described above. 
     While the present disclosure has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments may be devised which do not depart from the scope of the disclosure as described herein. Accordingly, the scope of the disclosure should be limited only by the attached claims.
