     DETAILED DESCRIPTION OF THE INVENTION 
     One or more specific embodiments of the present invention will be described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers&#39; specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure. 
     When introducing elements of various embodiments of the present invention, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. 
     The disclosed embodiments are directed to systems and methods for a coupling system configured to help couple a gas turbine and a generator of a mobile power plant system. The mobile power plant system may be a trailer mounted system that is transported by ship, air, or road to the installation site. In some situations, the mobile power plant may be delivered to the installation site in a partially assembled state of components, with components mounted or disposed on one or more trailers (or other types of mobile bodies). For example, the gas turbine may be mounted on a wheeled turbine trailer and the generator may be mounted on a wheeled generator trailer. The mobile power plant system may be transported to a location in need of electricity, such as during an emergency, natural disaster, or other event resulting in insufficient electricity. Specifically, the disclosed embodiments include a coupling system associated with the turbine trailer of the power plant system. In certain embodiments, the coupling system may include a sliding system that may be utilized in the field to quickly couple the gas turbine with the generator. 
     Without the disclosed embodiments, coupling the generator and the turbine may take up to a few hours depending on various environmental factors. For example, during transportation of the mobile power plant system, the coupling system may be mounted on a gas turbine enclosure and may be configured to enclose various components of the gas turbine within the gas turbine enclosure. In this manner, components of the gas turbine may be secured within the gas turbine enclosure during transportation. Without the disclosed embodiments, the coupling system may be manually disassembled and physically removed from the gas turbine enclosure prior to assembly of mobile power plant system. Specifically, without the disclosed embodiments, the coupling system may be manually disassembled and detached from the gas turbine enclosure to expose an opening through the gas turbine enclosure. The generator may be aligned and coupled to the gas turbine through the opening, in order to assemble the mobile power plant system and generate electricity. However, manually disassembling and removing one or more components of the coupling system from the gas turbine enclosure prior to coupling the gas turbine and the generator may result in slower installation and commissioning speeds, thereby increasing downtime and revenues lost. Accordingly, it may be beneficial to provide for systems and methods for improving the installation and commissioning speed of the mobile gas turbine system. 
     The disclosed embodiments are directed to a coupling system that may be quickly disassembled prior to assembly of the mobile power plant system. Specifically, the disclosed embodiments include a coupling system disposed on a gas turbine enclosure mounted on a turbine trailer. In certain embodiments, the coupling system may include a sliding system that may be utilized to separate one or more components of the coupling system, thereby exposing an opening through the gas turbine enclosure through which the generator may be coupled to the gas turbine. In particular, the disclosed embodiments may allow the coupling system to be disassembled without being detached from the gas turbine enclosure, as further described in detail below. 
     In certain embodiments, one or more components of the coupling system may be associated with a sliding system, and may be disposed on a surface of the gas turbine enclosure. For example, the coupling system may include a first and a second component coupled to rails of the sliding system. In certain embodiments, the first and second components of the coupling system may be separated by sliding each component along the rails of the sliding system, thereby exposing an opening in the turbine enclosure. The generator may be coupled to the gas turbine through the opening. In certain embodiments, an operator may separate the coupling system by manually engaging each component of the coupling system and sliding them apart along the sliding system. In particular, the sliding system may be utilized to expose the opening through the turbine enclosure without detaching the coupling system from the surface of the gas turbine enclosure. In certain embodiments, one or more components of the coupling system may include a drive system (e.g., electric or fluid drive). For example, the drive system may include a liquid or gas driven piston and shaft assembly, an electrical motor driven shaft, a rack and pinion system, a rotary screw system, or any combination thereof. The drive system may be configured to automatically separate the coupling system along the sliding system without operator intervention. Further, in certain embodiments, each component of the coupling system may include a manual crank, which may be utilized by the operator to separate the coupling system along the sliding system. These and other embodiments may be described in further detail below. 
     Turning now to the drawings,  FIG. 1  is a block diagram of an embodiment of a mobile power plant system  10  illustrating a coupling system  12  associated with a sliding system  14 . Specifically, the mobile power plant system  10  includes one or more trailers  16  that are configured to transport turbomachinery (e.g., one or more components of the mobile power plant system  10 ) to a desired location, such as to an installation site (e.g., on-site location) to meet power demands of customers where permanent power plants may not be able to deliver power. In certain embodiments, the mobile power plant system  10  includes a turbine trailer  18  (e.g., wheeled turbine trailer) and a generator trailer  20  (e.g., wheeled turbine trailer) to transport one or more components of the mobile power plant system  10  to the installation site. For example, the turbine trailer  18  may be configured to transport a gas turbine  22  (e.g., a gas turbine engine, a steam turbine, a hydroturbine, a wind turbine, or any turbine system) to an installation site. Further, the generator trailer  20  may be configured to transport a generator  24  configured to generate power for the mobile power plant system  10 . The turbine trailer  18  and the generator trailer  20  may include a frame, a base, sidewalls, wheels, axles, and other structural components that may help transport components of the mobile power plant system  10  to the installation site. 
     In particular, the turbine trailer  18  may be configured to move the gas turbine  22  into alignment with the generator  24  before the gas turbine  22  is coupled to the generator  24 . Likewise, the generator trailer  20  may be configured to move the generator  24  into a position where it may be aligned with the gas turbine  22 . For example, the generator trailer  20  supporting the generator  24  may be moved into a first position. In certain embodiments, the turbine trailer  18  supporting the gas turbine  22  may move in a reverse direction  28  into the generator trailer  20 , such that a tail end  30  of the turbine trailer  18  (e.g., relative to a gooseneck  32  of the turbine trailer  18 ) is moved towards a tail end  34  of the generator trailer  20  (e.g., relative to a gooseneck  36  of the generator trailer  20 ). In certain embodiments, the turbine trailer  18  may move in the reverse direction  28  to couple with the generator trailer  20 . In such embodiments, the generator trailer  20  may remain stationary in the first position while the turbine trailer  18  is moved in the reverse direction  28  into the first position so that the gas turbine  22  may be rotationally coupled to the generator  24 . While the illustrated embodiments describe the turbine trailer  14  moving in the reverse direction  28  as the generator trailer  20  is stationary, it should be noted that in other embodiments, the generator trailer  20  may move towards the stationary turbine trailer  18  and/or both trailers  18 ,  20  may move towards one another during the alignment and coupling process. 
     Specifically, in certain embodiments, the gas turbine  22  may be coupled to the generator  24  via a common shaft  26  during assembly of the mobile power plant system  10 . In certain embodiments, the gas turbine  22  may include a turbine  23  coupled to a compressor  25  via the common shaft  26 . The compressor  25  may intake oxidant (e.g., air, oxygen, oxygen-enriched air, oxygen-reduced air, etc.) via an air intake  27 . The compressor  25  may compress the inlet air, forming pressurized air (e.g., compressed air) by rotating blades within the compressor  25 . The pressurized air may enter a fuel nozzle  29  and mixes with a fuel  31  (e.g., gas fuel, liquid fuel, etc.) to form an air-fuel mixture. The fuel nozzle  29  may direct the air-fuel mixture into a combustor  33 . The combustor  33  ignites and combusts the air-fuel mixture, to form combustion products. The combustion products are directed to the turbine  23 , where the combustion products expand and drive blades of the turbine  23  about the common shaft  26 . The gas turbine  22 , once coupled to the generator  24 , may drive the generator  24  (e.g., electrical generator) via the common shaft  26  to generate electricity. Eventually, the combustion products may exit the gas turbine  22  as exhaust gases. In certain embodiments, various turbomachinery components may be utilized or manipulated prior to the coupling of the gas turbine  22  and the generator  24 . For example, in certain situations, the coupling system  12  may be utilized to help couple the gas turbine  22  with the generator  24 , as further described below. 
     In certain embodiments, the coupling system  12  may be utilized to help couple the gas turbine  22  with the generator  24  during assembly and commissioning of the mobile power plant system  10 . Specifically, in certain embodiments, the coupling system  12  may be disposed on an exterior surface  38  of a turbine enclosure  40 . For example, the exterior surface  38  may be proximate to the tail end  30  of the turbine trailer  18 . The turbine enclosure  40  may be a housing configured to secure various components of the gas turbine  22  during transportation of the mobile power plant system  10 . In certain embodiments, the coupling system  12  may be disposed over an opening  42  within the turbine enclosure  40  during transportation of the mobile power plant system  10 . Accordingly, during assembly of the mobile power plant system  10 , the coupling system  12  may be separated to expose the opening  42 , thereby allowing an access point through which the gas turbine  22  may be coupled with the generator  24 . Specifically, the common shaft  26  of the generator  24  may be coupled to the gas turbine  22  via the opening  42 . Indeed, while the illustrated embodiment depicts the coupling system  12  disposed on the exterior surface  38  of the turbine enclosure  40 , it should be noted that in certain embodiments, the disclosed coupling system  12  may be disposed on other mobile bodies (e.g., generator trailer  24 ). 
     Without the disclosed embodiments, the coupling system  12  may be manually disassembled and physically removed from the exterior surface  38  of the turbine enclosure  40 , which may result in slower installation and commissioning speeds, thereby increasing downtime and revenues lost. Accordingly, the disclosed embodiments improve efficiency of installation and commissioning speeds by utilizing the sliding system  14 , as further described below. 
     In certain embodiments, the coupling system  12  may include the sliding system  14 , and one or more components of the coupling system  12  may be separated via the sliding system  14  to expose the opening  42  within the turbine enclosure  40 . Specifically, as further described with respect to  FIGS. 2-3 , the coupling system  12  may be separated by sliding one or more components or portions of the coupling system  12  along the sliding system  14 . In this manner, the coupling system  12  may be separated without being detached from the exterior surface  38  of the turbine enclosure  40 . Accordingly, the sliding system  14  may enable the coupling system  12  to quickly provide an access point (e.g., the opening  42 ) through which the generator  24  may be coupled to the gas turbine  22  (disposed inside the turbine enclosure  40 ), as further described in detail with respect to  FIGS. 2-3 . 
       FIG. 2  is a perspective view of the coupling system  12  of  FIG. 1  in a first closed position  50 . Specifically, in the illustrated embodiment, the coupling system  12  is disposed on the exterior surface  38  of the turbine enclosure  40 . In particular, the exterior surface  38  of the turbine enclosure  40  may be proximate to the tail end  30  of the turbine trailer  18 . In certain embodiments, the coupling system  12  may be configured to cover the opening  42  disposed within the turbine enclosure  40  during transportation of the mobile power plant system  10 . In certain embodiments, the first closed position  50  may be the configuration of the coupling system  12  during transportation of the gas turbine  22  mounted turbine trailer  18 . The coupling system  12  may be in the first closed position  50  until the mobile power plant system  10  is ready to be assembled and commissioned (e.g., until the coupling process of the gas turbine  22  with the generator  24 ). In certain embodiments, after the gas turbine  22  is coupled to the generator  24 , the coupling system  12  may be reassembled in a second closed position, as further described with respect to  FIG. 5 . In certain embodiments, the coupling system  12  may separate to expose the opening  42  during an installation and commissioning of the mobile power plant system  10 . In particular, one or more components of the coupling system  12  may be separated via the sliding system  14  to expose the opening  42 , so that the gas turbine  22  may be coupled with the generator  24  through the opening  42 . In the following discussion, reference may be made to an X-axis  53 , a Y-axis  51 , and a Z-axis  57 . 
     In certain embodiments, the coupling system  12  may be formed of one or more components, and each of the one or more components may be coupled to a portion of the sliding system  14 . For example, in the illustrated embodiment, the coupling system  12  includes a first component  52  (e.g., a first sliding door) and a second component  54  (e.g., a second sliding door) each coupled to a portion of the sliding system  14 . In certain embodiments, the sliding system  14  include rails  55  (e.g., linear guide paths, tracks, wheels, linear bearings, low friction bushings, etc.) mounted on the exterior surface  38  of the turbine enclosure  40 . The rails  55  may be formed of any durable material that may support one or more portions of the coupling system  12 , such as, for example, aluminum, steel, plastic, etc. Furthermore, in certain embodiments, the sliding system  14  may include one or more sets of rails  55  extending along the X-axis  53 , such as a first set of mating rails  55  proximate to a top edge  61  of the turbine enclosure  40  and a second set of mating rails  55  proximate to a bottom edge  63  of the turbine enclosure  40 . In certain embodiments, the first and second sets of mating rails  55  may mate with a T-shaped protrusion into a T-shaped slot, a J-shaped protrusion into a J-shaped slot, etc. 
     In particular, each component of the coupling system  12  (e.g., the first component  52 , the second component  54 ) may include an associated portion or portions of the rails  55 , which may be utilized to slide the components apart to expose the opening  42 , as further described with respect to  FIG. 3 . In certain embodiments, each component (e.g., the first component  52 , the second component  54 , etc.) of the coupling system  12  may be coupled to a rail guided structure that may be removably mounted within the frame or support structure of the rails  55 . In certain embodiments, the rail guided structure of each component may be a protrusion (e.g., wheels, extension, etc.) that forms a male/female connection with the frame of the rails  55 , and that may roll along the length of the rails  55  without disengaging. For example, the rails  55  of the sliding system  14  may extend along the X-axis  53  of the turbine trailer  18 . Further, each component of the coupling system  12  may be separated when an operator engages the component and slides the component along the X-axis  53  in opposite directions. For example, the first and second components  52 ,  54  may be separated by linearly moving them in opposite directions. 
     In the illustrated embodiment, the coupling system  12  may be formed of two components (e.g., the first component  52 , the second component  54 ), which may be secured together with one or more removable fasteners  56 . The one or more removable fasteners  56  may include threaded receptacles, bolts, screws, nuts, clamps, male/female joints, latches, snap-fit couplings, spring-loaded couplings, buckles, retaining clips or threads, or any combination thereof. In particular, the removable fasteners  56  may be removed before the components of the coupling system  12  are separated via the sliding system  14 . Further, in certain embodiments, the removable fasteners  56  may be reattached when the components of the coupling system  12  are brought back together after the gas turbine  22  is coupled to the generator  24 , as further described with respect to  FIG. 5 . 
     In the illustrated embodiment of  FIG. 2 , two components (e.g., the first component  52 , the second component  54 ) of the coupling system  12  which may be separated to expose the opening  42  are depicted. For example, a vertical split along the Y-axis  51  may separate the coupling system  12  into two generally equally sized compartments. In other embodiments, the coupling system  12  may include three or more components. For example, in certain embodiments, the coupling system  12  may include 3, 4, 5, 6, 7, 8, 9, 10 or more components. For example, the coupling system  12  may be split along any axis (e.g., X-axis  53 , Y-axis  51 , Z-axis  57 ) into any number of components, and each component may be coupled to a portion (e.g., the rails  55 ) of the sliding system  14 . Each of the one or more components may be separated via the sliding system  14  to expose the opening  42 . 
     In certain embodiments, each of the one or more components of the coupling system  12  may be coupled to one or more handles  59  which may be utilized by an operator to separate and slide the one or more components of the coupling system  12  along the sliding system  14 . In certain embodiments, the handles  59  may be a knob, a grip, a handgrip, a protrusion, a doorknob, a combination thereof, or any mechanism that may be utilized by an operator to engage a component of the coupling system  12 . For example, in certain embodiments, the operator may actuate a latch to unlock the first and the second components  52 ,  54 , and may further engage the latch to slide the first and the second components  52 ,  54  along the sliding system  14 . 
     Further, in certain embodiments, a stopping mechanism  58  may be coupled to the rails  55  at an outer edge  60  of the sliding system  14 . In certain embodiments, the stopping mechanism  58  may be a stopper formed of a material resilient to impact (e.g., rubber, plastic, elastomer, etc.), and/or may be any mechanical component (e.g., blocker, stopper, locking pegs, etc.) configured to prevent each component of the coupling system  12  from disengaging from the sliding system  14 . In certain embodiments, the stopping mechanism  58  may be configured to block further movement of the components of the coupling system  12  after the components have been separated a particular distance. In certain embodiments, the stopping mechanism  58  may include one or more magnets that are configured to both stop the component of the coupling system  12  along the rails  55  and securely hold (e.g., lock) the component along the outer edge  60  of the sliding system  14 . In certain embodiments, the stopping mechanism  58  may include other features that prevent the components of coupling system  12  from disengaging from the sliding system  14 , as further described with respect to  FIG. 4 . 
       FIG. 3  is a perspective view of the coupling system  12  of  FIG. 1  in an open position  62 . As noted above, the coupling system  12  may be disposed on the exterior surface  38  of the turbine enclosure  40 , and may be proximate to the tail end  30  of the turbine trailer  18 . In certain embodiments, the coupling system  12  may be configured to cover the opening  42  within the turbine enclosure  40  during transportation of the turbine trailer  18  to the installation site. In particular, one or more components of the coupling system  12  may separate along the X-axis  53  to expose the opening  42  prior to the installation and commissioning of the mobile power plant system  10 . For example, the one or more components of the coupling system  12  may be separated via the sliding system  14  to expose the opening  42 , so that the gas turbine  22  (mounted on the turbine trailer  18 ) may be coupled with the generator  24  (mounted on the generator trailer) through the opening  42 . 
     In certain embodiments, a shaft alignment guide  64  associated with the gas turbine  22  may be disposed within the turbine enclosure  40 , and may be utilized after the first and second components  52 ,  54  of the coupling system  12  are separated. Specifically, once the coupling system  12  is in the open position  62 , the shaft  26  of the generator  24  may be coupled to the gas turbine  22  via the shaft alignment guide  64 . In particular, the components of the coupling system  12  may be separated a first distance  66  along the X-axis  53 , such that the coupling process between the gas turbine  22  and the generator  24  may commence without interference from a portion of the coupling system  12 . The first distance  66  may be any distance shorter than or equal to a width of the turbine enclosure  40  and/or the turbine trailer  18 . Further, it should be noted one or more hinged joints coupled to the coupling system  12  and/or the sliding system  14  may be utilized to extend the components of the coupling system  12  away from the exterior surface  38  of the turbine enclosure, as further described with respect to  FIG. 4 . 
       FIG. 4  is a perspective view of the coupling system  12  of  FIG. 1  in the open position  62  and having one or more hinged joint  68 . In certain embodiments, as noted above, the first and second components  52 ,  54  of the coupling system  12  may be separated from one another to expose the opening  42  within the turbine enclosure  40 . For example, as noted above, each of the one or more components of the coupling system  12  may be coupled to the rails  55  of the sliding system  14 . In certain embodiments, an operator may engage the components of the coupling system  12  to separate the components along the X-axis  53  via the sliding system  14 . In certain embodiments, the components of the coupling system  12  may be separated via a drive system, as further described with respect to  FIG. 6 . Furthermore, in certain embodiments, the components of the coupling system  12  may be separated via a manual hand crank, as further described with respect to  FIG. 7 . 
     In certain embodiments, the first and second components  52 ,  54  of the coupling system  12  may be separated along the X-axis  53  to the first distance  66 , as described with respect to  FIG. 3 . Furthermore, in certain embodiments, the first and second components  52 ,  54  may be further extended via one or more hinged joints  68  that couple the components  52 ,  54  to the outer edge  60  of the sliding system  14 . For example, the first and second components  52 ,  54  may be configured as hinged doors or hinged sliding doors. Specifically, in certain embodiments, the stopping mechanism  58  disposed at the end of the rails  55  may be a hinged joint configured to open the components  52 ,  54  along the direction  70 , thereby creating a second distance  70  between the first and second components  52 ,  54 . The second distance  70  may be greater than the first distance  66 , thereby allowing for more space between the components of the coupling system  12  for assembling and coupling the gas turbine  22  and generator  24 . In certain embodiments, the first and second distances  66 ,  70  may be a radius and/or a direction. In certain embodiments, the hinged joint  68  may be disposed anywhere along the rails  55  along the X-axis  53 , and the hinged joint  68  may be positioned based on desired second distance  70  between the components  52 ,  54 . 
       FIG. 5  is a perspective view of the coupling system  12  of  FIG. 1  in a second closed position  74 , where the coupling system  12  includes a shaft access  76 . As noted above, in certain embodiments, the coupling system  12  may be configured to cover the opening  42  disposed within the turbine enclosure  40  during transportation of the mobile power plant system  10 . Specifically, the first closed position  50  may be the configuration of the coupling system  12  during transportation of the turbine trailer  18  and prior to the coupling of the gas turbine  22  with the generator  24 . As noted above, prior to coupling the gas turbine  22  and the generator  24  via the shaft  26 , the coupling system  12  may be separated along the sliding system  14 . In particular, the coupling system  12  may be separated without disassembling and removing one or more components of the coupling system  12  from the exterior surface  38  of the turbine enclosure  40 , thereby improving installation and commissioning speeds. Furthermore, in certain embodiments, after the gas turbine  22  is coupled to the generator  24 , the coupling system  12  may be reassembled into second closed position  74 , as further described in detail below. 
     Specifically, the second closed position  74  may be formed by engaging the one or more components of the coupling system  12  back together via the sliding system  14 . For example, in certain embodiments, the first component  52  and the second component  54  may be reassembled and secured together with the one or more removable fasteners  56  after the generator  24  and the gas turbine  22  are coupled. In certain embodiments, the coupling system  12  may include a grommet  78  that is formed after the generator  24  and the gas turbine  22  are coupled together. Specifically, grommet  78  may be formed of a rubber, a plastic, or any other flexible or malleable material. In certain embodiments, an operator may form the shaft access  76  within the grommet  78  by cutting out a portion of the grommet material. 
     The dimensions of the shaft access  76  may be determined based on an amount of clearance desired around the shaft  26  during operation of the mobile power plant system  10 . For example, the diameter  80  (e.g., inside diameter) of the shaft access  76  may be greater than the diameter of the shaft  26  by a few centimeters, a few inches, or a few feet, depending upon the dimensions of the shaft  26  and depending upon the desired distance between the shaft  26  and an inner edge  82  (e.g., inner edge diameter) of the grommet  78 . In certain embodiments, the grommet  78  may be coupled to a top surface  84  of the coupling system  12  with one or more attachment mechanisms  86 . In certain embodiments, the attachment mechanisms  86  may include one or more bolts, threaded receptacles, screws, nuts, clamps, male/female joints, buckles, retaining clips or threads, or a combination thereof. 
       FIG. 6  is a perspective view of the coupling system  12  of  FIG. 1 , where the coupling system  12  is associated with a drive system  90  associated with the sliding system  14 . In certain embodiments, an operator may separate the coupling system  12  by manually engaging each component (e.g., the first and second components  52 ,  54 ) of the coupling system  12  and sliding them apart along the sliding system  14 . Further, in certain embodiments, the drive system  90  may be configured to automatically separate the coupling system  12  along the sliding system  14  without operator intervention. In certain embodiments, the drive system  90  (e.g., electric or fluid drive) may include a liquid or gas driven piston and shaft assembly, an electrical motor driven shaft, a rack and pinion system, a rotary screw system, or any combination thereof. 
     For example, the drive system  90  may include one or more electrical motors  92 , and each electrical motor  92  may be associated with an actuator system  94 . Each component (e.g., the first and second component  52 ,  54 ) of the coupling system  12  may be coupled to the actuator system  94 , and each actuator system  94  may be communicatively coupled to the electric motor  92 . In certain embodiments, a single electrical motor  92  may be utilized within one or more components of the coupling system  12 , and may be configured to regulate the operations of one or more actuator systems  94 , where each actuator system  94  is coupled to a component of the coupling system  12 . Further, each electrical motor  92  and the actuator system  94  may be communicatively coupled to a controller  96 , which includes a processor  98  and a memory  100 . The controller  96  may be configured to independently coordinate and control the movement of each component of the coupling system  12 . 
     In certain embodiments, the memory  100  may include any suitable non-transitory, tangible, computer-readable medium having executable instructions. The controller  96  may be suitable for executing various monitoring or controlling operations related to the coupling system  12  or the one or more components of the coupling system  12 . In certain embodiments, the coupling system  12  may include a display through which an operator (e.g., engineer or technician) may monitor the components of the coupling system  12  and/or the general installation and commissioning process of the mobile power plant system  10 . The controller  96  may be any type of computing device suitable for running software applications, such as a laptop, a workstation, a tablet computer, or a handheld portable device (e.g., personal digital assistant or cell phone). Indeed, the controller  96  may include any of a variety of hardware and/or operating system platforms. In some embodiments, the computer may host industrial control software, such as a human-machine interface (HMI) software, a manufacturing execution system (MES), a distributed control system (DCS), a supervisor control and data acquisition (SCADA) system, and so forth. In certain embodiments, the controller  96  may be included within a control system or a controller configured to monitor and/or control the operations of the mobile power plant system  10 . 
       FIG. 7  is a perspective view of the coupling system  12  of  FIG. 1 , where the coupling system  12  is associated with a manual hand crank  102 . In the illustrated embodiment, a single manual hand crank  102  is depicted as coupled to a single component (e.g., the first component  52 ) of the coupling system  12 . In certain embodiments, one or more manual hand cranks  102  may be utilized with each of the one or more components of the coupling system  12 . In certain embodiments, the manual hand crank  102  may include an arm, a rotating shaft, and a disk that are coupled to a portion of the sliding system  14 . Furthermore, in certain embodiments, the manual hand crank  102  may include one or more components coupled to the sliding system  14  and configured to transfer torque to the sliding system  14 . Indeed, the manual hand crank  102  may include any components that may be utilized to convert circulation motion received from an operator into linear sliding motion for moving components of the coupling system  12  along the X-axis  53 . For example, the manual hand crank  102  may include gears, transmission, pulleys, or cables that are coupled to the sliding system  14 , and which may be configured to transfer torque to the sliding system  14 . 
     Technical effects of the invention include a coupling system  12  configured to help couple the gas turbine  22  and the generator  24  of the mobile power plant system  10 . In certain embodiments, the coupling system  12  may be disposed on the turbine enclosure  40  mounted on the turbine trailer  18  and configured to enclose components of the gas turbine  22  during transportation of the mobile power plant system  10 . The coupling system  12  may include the sliding system  14  that may be utilized to separate one or more components (e.g., the first and second components  52 ,  54 ) of the coupling system  12 , thereby exposing the opening  42  through the turbine enclosure  40  through which the generator  24  may be coupled to the gas turbine  22 . In certain embodiments, an operator may separate the coupling system  12  by manually engaging each component (e.g., the first and second components  52 ,  54 ) of the coupling system  12  and sliding them apart along the sliding system  14 . In particular, the sliding system  14  may be utilized to expose the opening  42  through the turbine enclosure  40  without detaching the coupling system  12  from the exterior surface  38  of the turbine enclosure  40 .
