Title: Control Package Container

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the priority benefit of U.S. provisional patent application No. 61/109,484, titled “Lower Marine Riser Package Container,” filed Oct. 29, 2008. This related application is hereby incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     Embodiments of the inventive subject matter generally relate to the field of containers, and more particularly, to containers that are configured to transport a pressure controls package, or MUX control package for a lower marine riser package (LMRP). 
     The pressure control package is an oilfield tool which couples to a blow out preventer (BOP) and/or a drill string. The pressure control package is an electronic, and/or hydraulic controls package. The pressure control package typically controls pressure in a blowout preventer, and/or another portion of the wellbore. The pressure control package helps prevent a blow out during drilling operations and/or in the operation of the stack and associated equipment. The pressure control package is typically installed in a subsea environment near the BOP. All or portions of the pressure control package are replaced often during the life of the well. Thus, multiple pressure control packages are delivered to an offshore platform during the life of the well. Each of the pressure control packages is very expensive. Further, damage to the pressure control package may not be realized until the pressure control package is already installed on the BOP. If damage is discovered to the pressure control package after the pressure control package is installed on the drill string and/or the BOP, rig time and well production time is lost as a result. 
     SUMMARY 
     Embodiments described herein include a container. The container comprising a base configured to hold a control package. The base may have a frame for supporting the weight of the control package and one or more receiving members configured to receive a portion of the control package.

The one or more surface controls  104 , and the subsea control package  114  may control any number of wellbore conditions and equipment actions during the drilling of the wellbore. For example, the controls  104  and/or  114  may control pressure in the wellbore, the amount of drilling fluid pumped into the wellbore, the production rate, the drilling speed, and the like. The subsea control package  114  consists of controls that are easily damaged during shipping. One or more containers  120  are used to transport the subsea control package  114  to and from the wellbore work area. 
       FIG. 2  depicts a schematic drawing of the subsea control package  114  according to one embodiment. The subsea control package  114  may include an upper pod  200  and a lower pod  202 . The upper and lower pods  200  and  202  may have any number of control systems within the pods. The upper and lower pods  200  and  202  may include an air/water tight exterior configured to prevent the control systems from exposure to the subsea environment. In the embodiment shown, the lower pod  202  may include one or more pod connector devices  204 . The one or more pod connector devices  204  are configured to secure the pods  202  and  200  to the subsea equipment, for example the subsea shutoff device  110 , the blow out preventer  106 , and/or the lower marine riser package and the like. As shown, the one or more pod connector devices  204  are a plurality of cylindrical legs. Each of the cylindrical legs may be configured to secure to an aperture in the subsea equipment, thereby securing the pod  202  to the subsea equipment. Although the one or more pod connector devices  204  are described as cylindrical legs, it should be appreciated that the pod connector devices  204  may be any suitable devices for securing the pods  202 , and  200  to the subsea equipment including, but not limited to one or more pins, one or more cross-sectionally square legs, one or more cross-sectionally rectangular legs, one or more holes or apertures in the bottom of the pods for receiving a device, one or more hooks, and the like. In one embodiment, the lower pod  202  is configured to have four cylindrical legs for coupling to the subsea equipment, and the upper pod  200  is configured to couple to the lower pod  202 . 
     One or more of the pod connector devices  204  may be configured to include a fastening device  206  for securing the pods  204  to the subsea equipment. As shown, the fastening device is an aperture  208  configured to secure to one or more subsea pins or rods (not shown) when engaged with the subsea equipment. The one or more subsea pins may ensure that the pods  200  and/or  202  do not disengage the subsea equipment inadvertently. Although the fastening device  206  is described as an aperture  208  and a pin it should be appreciated that the fastening device may be any suitable device for securing the pods  200  and/or  202  to the subsea equipment including but not limited to a clamp, a bolt and nut, a threaded connection, keys, carter key, a buckle, pins, and the like. 
       FIG. 3  depicts a perspective view of the container  120  configured to store and transport the subsea control package  114 , and/or the pods  200  and  202 . The container  120  may include a lifting cage  300  and a base  302 . The lifting cage  300  may be selectively coupled and uncoupled to the base  302 . In the coupled position, the lifting cage  300  and the base  302  form the container  120  for storing and transporting the pods  200  and/or  202  as one unit. The pods  200  and/or  202  are secured to the base  302 , as will be described in more detail below. The base  302  prevents the pods  200  and/or  202  from substantially moving within the container  120 . With the pods  200  and/or  202  secured to the base  302  and the lifting cage  300  coupled to the base  302 , the pods  200  and/or  202  are securely stored within the container  120 . The container  120  substantially prevents damage to the pods  200  and/or  202  during shipping and storing by preventing direct impact to the pods  200  and/or  202  by other equipment. Thus, if the container  120  is impacted by a piece of equipment, personnel, vehicles, tools and the like, the container  120  will substantially absorb the effects of the impact. Thus, the pods  200  and/or  202  may be substantially protected by the container  120  during transport. Further, the container  120  may protect the pods  200  and/or  202  from the environment. 
     The lifting cage  300  may comprise a top  304  and four sides  306 . The top  304  may be fixedly coupled to the tops of each of the four sides  306 . The top  304  and the four sides  306  form a box which is missing one side, for example the bottom. As shown, the top  304  has a rectangular shape when looking at the top in plan view. In this embodiment, two of the sides  306  have a longer length, in the direction of the top  304 , than the other two sides  306 . Although, the lifting container  300  is described as having a rectangular top  304  and four sides  306 , it should be appreciated that the container may have any suitable shape and number of sides for containing the pods  200  and/or  202  including, but not limited to a circular top with one cylindrical side, a square top with four equal length sides, a triangular top with three sides, a pentagon top with five sides, a hexagonal top with six sides, any polygon top with an equal number of sides, a rectangular prism, and the like. 
     Although the lifting cage  300  is described as having the top  304  and the four sides  306  fixedly coupled to one another, it should be appreciated that the top  304  may be removably coupled to each of the four sides  306 , in an alternative embodiment. In this embodiment, the fours sides  306  may be uncoupled from the top  304  in order to store the empty container  120  in a more efficient manner when not in use. For example, a user may uncouple the top  304  from the sides  306  and store the base  302 , the top  304  and the sides  306  in a parallel fashion thereby minimizing storage space when not in use. 
     The top  304  may comprise one or more top structural members  308  coupled to one another to form a perimeter of the top  304 . For example, in the embodiment wherein the top is rectangular shaped there may be four structural members  308  forming a rectangular perimeter to the top  304 . The interior of the top  304  may comprise a top inner member  310 . Each of the sides  306  may comprise side structural members  312  and a side inner member  314 . The side structural members  312  may be fixedly coupled to, or removeably coupled to, each of the corners of the top  304 . The structural members  308  and/or  312  may be coupled to one another be any suitable method including, but not limited to, welding, bolting, screwing, riveting, nailing, and the like. Further, the structural members  308  and  312  may be one continuous formed piece thereby removing the need to connect the structural members  308  and  312  to one another. The structural members, as shown, are structural box tubing; however, it should be appreciated that the structural members may be any suitable structural members, or combination of structural members, including, but not limited to pipe, tubing, conduit, I-beams, channels, angle iron, solid cylinders, solid members having any suitable cross sectional shape for example square, WT members, and the like. 
     The inner members  310  and/or  314  may be formed of any suitable material including, but not limited to, sheet metal, vinyl, plate metal, plastic, grating, stamped plate, plated metal, a series of bars, and the like. The inner members  310  and/or  314  may couple to the structural members  308  and  312  by any suitable method including, but not limited to, welding, clips, brackets, nails, rivets, screws, bolts, press fittings, and the like. Although, the top  304  and sides  306  are described as having structural members  308  and  312  and inner members  310  and  314 , it should be appreciated that the top  304  and/or the sides  306  may each be a solid, or composite member. For example, any of the sides and/or top may comprises a plate, or a plurality of structural members having no, or any of the inner members described herein between the structural members, keys, carter key, a buckle, pins and the like. 
     The lifting cage  300  may have one or more container locks for coupling the lifting cage  300  to the base  302  as will be discussed in more detail below. 
     The lifting cage  300  may include one or more lifting members  316 . The lifting members  316  may be configured to allow the lifting cage  300  to be lifted by a hoisting mechanism. The hoisting mechanism may be any suitable hoisting mechanism including, but not limited to, a crane, a cherry picker, a drilling rig, and the like. As shown, the lifting members  316  are lifting lugs substantially located in the four corners of the top  304  of the lifting cage  300 . The lifting lugs may have a loop, or hook, to which a rigging from the hoisting mechanism may be secured. The lifting members  316  may be positioned on the lifting cage  300  in order to balance the lifting cage  300 , and/or container  120  when lifting. Although the lifting members  316  are described as being lifting lugs it should be appreciated that the lifting members  316  may be any suitable device for allowing the hoisting mechanism to couple to the lifting cage  300  including, but not limited to, hooks, eye hooks, apertures in the lifting cage  300 , magnetic surfaces for lifting with magnets, and the like. The hoisting mechanism may be used to lift the lifting cage  300  off of the base  302  when the lifting cage  300  is not coupled to the base  302 . Further, the hoisting mechanism may be used to lift the container  120 , either empty or with the pod  200  and/or  202 . 
     The lifting cage  300  may further include one or more forklift eyes  318 , shown only on the base  302 . The lifting cage forklift eyes may be located in the top  304 , and/or through a portion of the sides  306 . The lifting cage forklift eyes may allow the user to lift the lifting cage  300  off of the base  302  without the need to use the hoisting mechanism. 
       FIG. 4  depicts a perspective view of the container  120  with the lifting cage  300  uncoupled from the base  302 . The base  302  may include one or more base structural members  400 .

The base structural members  400  located within the interior of the perimeter are shown as one structural member running along the central longitudinal axis of the container  120  and at least two structural members running perpendicular to the longitudinal axis of the container  120 . Although the base is shown with the base structural members  400  running around the perimeter of the base  302  and with three base structural members  400  in the interior of the perimeter of the base  302 , it should be appreciated that the base structural members  400  may have any suitable configuration for supporting the lifting cage  300 , and the subsea control package  114 , and/or pods  200  and  202 , including, but not limited to, a solid floor structural member, a series of structural members running along the longitudinal axis of the container  120 , a series of structural members running perpendicular to the longitudinal axis of the container  120 , a plurality of structural members running in both the longitudinal axis and the perpendicular axis of the container  120 , a plurality of structural members running along the longitudinal axis of the container  120  and one structural member running perpendicular to the longitudinal axis, structural members forming a substantially evenly spaced checkered pattern in both the longitudinal axis of the container  120  and the perpendicular axis of the container  120 , diagonal structural members, diagonal structural members running in two directions in a angled checkered pattern and the like. The base structural members  400  are shown as box tube structural members; however, it should be appreciated that the base structural members  400  may be any suitable structural members, including any of the structural members described herein. The base structural members  400  may have any suitable configuration so long as the base structural members  400  are capable of supporting the subsea control package, and/or the pods  200  and  202 . Although, the base structural members are described as running along the longitudinal and perpendicular axis of the container  120 , it should be appreciated that when the container  120  is square, or another shape, the longitudinal axis and the perpendicular axis may be an arbitrary axis in any direction substantially perpendicular to one another. 
     There may be a base interior member  402  between the base structural members  400  as shown in  FIG. 4 . The base inner members  402  may be formed in a similar manner as the top inner members  310  and the side inner members  314 . Further, the base inner members  402  may be coupled to the base structural members  400  in a similar manner as described for the inner members  310  and  314 . 
     The base  302  may include one or more fork lift eyes  318  on the longitudinal axis side, and or the side perpendicular to the longitudinal axis of the container  120 . The fork life eyes allow a user to engage the base  302 , and/or the container  120  with the fork life, and/or pallet jack forks. Once the fork lift eyes are engaged with the forks, the user may lift and move the base  302  and/or container  120  to another location for transport and/or storage.

The carbon steel may be coated with an epoxy coat in order to protect the carbon steel from rusting in the harsh sea environment. Further, the container  120  may be any suitable combination of materials including, but not limited to, stainless steel, chrome, plastic, wood, and/or the like. 
     In one embodiment, the container  120  is configured for storing and transporting the upper pod  200  and the lower pod  202  separately.  FIGS. 5A ,  5 B,  6 A,  6 B,  7 A and  7 B will now be briefly discussed in conjunction with this specific embodiment. In this embodiment, the upper pod  200  is configured to couple to the lower pod  202  and the lower pod  202  is configured to couple to the subsea equipment with the lower pod connection device  204 . The lower pod connection device  204  may be a plurality of cylindrical legs. Each of the cylindrical legs of the lower pod  202  may be configured to secure to one of the receiving members  508  of the base  302 . The receiving members  508  in this example, are a plurality of cylindrical receiving members  508  having a central bore  526 , as shown in  FIG. 5B . The central bore  526  may be configured to receive at least a portion of the cylindrical leg of the lower pod  202 . In order to connect the lower pod to the base  302 , the pod clamp frame  510  may be removed from the base  302 . 
     The pod clamp frame  510  may be removed from the base  302  by removing the base fastening device  512  from the receiving member  508 . In one example, the base fastening device is the rod  600  configured to secure to the aperture  514  of the receiving members  508 . The rod  600  may be removed from the aperture  514  thereby allowing the pod clamp frame  510  to be lifted out of the receiving members  508  as shown in  FIG. 5B . The pod clamp frame  510  may then be secured, or stored, to the storage device  506 , or placed at another location, so long as the pod clamp frame  510  does not interfere with installation of the lower pod  202 . With the pod clamp frame  510  removed from the base  302 , the lower pod may be ready for securing to the base. 
     The lower pod  202  may be positioned over the base  302  in order to secure the lower pod  202  to the base, as shown in  FIG. 6A . The lower pod  202  may then be lowered, or moved, toward the base  302 . As the lower pod  202  is moved toward the base  302 , the legs, or lower pod connection devices  204 , of the lower pod  202  may enter the bore  526  of the receiving members  508 , as shown in  FIG. 6B . Although the legs are described as entering into the bore  526 , it should be appreciated that the legs may include a bore, not shown, for receiving the receiving members  508  in another embodiment. With the legs received in the receiving members  508  the aperture  208  of the legs may align with the aperture  514  of the receiving members  508 . The base fastening members  512  may then be used to secure the lower pod  202  to the base  302 . In one example, the base fastening members  512  comprise the rod  600 . The rod  600  may be slid through the apertures  208  and  508  in order to lock the lower pod  202  to the base  302 . Once the rod  600  is in place one or more pins  602  may be secured to the rod, as shown in  FIG. 6B , in order to lock the rod  600  in place. The rod  600  as shown is configured to secure through two of the legs of the lower pod  202  and two of the receiving members  508 , however, it should be appreciated that there may be a separate rod  600  for each of the legs and receiving members  508 . With the rods  600  locked in place the lower pod  202  is now secured to the base  302 , thereby preventing the lower pod  202  from moving substantially relative to the base  302 . The lifting cage  300  may then be moved to a position over the base  302  and lowered onto the base  302 . The lifting cage  300  may then lock to the base  302 , as described above, in order to secure the lifting cage  300  to the base  302 . The container  120  with the lower pod  202  secured inside is now free to be transported to another location. 
     When the user is ready to remove the lower pod  202 , the lifting cage  300  may be unlocked from the base  302 . The lifting cage  300  may then be lifted from the base  302  using the hoisting device or a fork lift. With the lifting cage  300  out of the way, the user may then remove unlock the base fastening device  512 . In one embodiment, the user may unlock the base fastening device  512  by removing the carver pins  602  from the rod  600  and pulling the rod  600  out of the apertures  512  and  204 . The lower pod  202  may then be lifted out of the base  302  using any suitable means including, but not limited to, a fork lift, a cherry picker, a hoisting means, manual lifting and the like. The user may then place the remove the pod clamp frame  510  from the storage device  506  and couple the pod clamp frame  510  to the base  302 . The lifting cage  300  may then be placed back on the base  302  in order to store the container  120  until it is needed again. 
     The container  120  may further be used to store and transport the upper pod  200 . In one embodiment, the upper pod  200  is configured to secure to the power pod  202  when in use. Therefore, the upper pod  200  does not have the legs of the lower pod  202 . In this embodiment, the upper pod  200  may have a substantially planar outer surface, for example, a cube shape, or rectangular prism shape. Although the upper pod  200  is described as having a cube or rectangular prism shape, it should be appreciated that the upper pod  200  may have any suitable shape for housing subsea controls including, but not limited to, an irregular shape, a combination of several shapes and the like. Due to the fact that the upper pod  200  does not have the legs, or pod connector devices  204 , the upper pod  200  must be secured to the base  302  using the pod clamp frame  510 . 
     The lifting cage  300  and the pod clamp frame  510  should be removed from the base  302  as described above and shown in  FIG. 7A . The upper pod  200  may then be placed on the base  302  between the receiving members  508 . Although the upper pod  200  is described as being placed between the receiving members  508 , it should be appreciated that the upper pod  200  may be located partially or wholly outside of the receiving members  508 . The upper pod  200  may be moved into position on the base  302  using any suitable method for moving the upper pod  200  including, but not limited to, a forklift, the hoisting device, a manual lift, a pallet jack, a cherry picker, and the like. With the upper pod  200  resting on the base  302 , the upper pod may be secured to the base  302 . 
     In one embodiment, the upper pod  200  may be secured to the base  302  using the pod clamp frame  510  of the pod support device  500 . The pod clamp frame  510  may be lowered, or moved, toward the base  302  with the upper pod  200  in place. The clamp member connector devices  516  may engage the receiving members  508  as the pod clamp frame  510  continue to moves toward the base  302 . In one embodiment, the clamp connector devices  516  are a fixed length sized configured to be installed at the same length. In this embodiment, the pod clamp frame  510  may be sized to secure a particular model of upper pod  200  to the base  302 . When the clamp member connector devices  516  are fully engaged to the receiving members  508 , the rod  600  may be place through the apertures  514  in order to secure the pod clamp frame  510  to the base  302 . The pod clamp frame  510  may prevent the upper pod  200  from substantially moving relative to the base  302 . 
     To substantially prevent the movement of the upper pod, an inner wall  548 , as shown in  FIG. 5B , of the pod clamp frame  510  may engage, or partially engage the outer surface of the upper pod  200 . Thus, the inner wall  548  may prevent the upper pod  200  from moving in a horizontal direction relative to the base  302 . Further, one or more hold down members  550  may engage or substantially engage the top facing surface of the upper pod  200 . The hold downs  550  may substantially prevent the upper pod from moving in the perpendicular direction relative to the base  302 . Any of the members engaging the upper pod  200  include the shock absorbing members and/or an intermediate dampening member between the upper pod and the members. The shock absorbing members may be any suitable dampening member including any of those described herein. 
     In an alternative embodiment, the clamp connector devices  516  may have a variable length, or variable height settings. In this embodiment, the height of the pod clamp frame  510  may be adjusted to match the size of different model pods. To this end, the clamp connector devices  516  may have several apertures in which the rod  600  may be secured to. The apertures may be located longitudinally along the length of the clamp connector devices  516 . Thus, by moving the rod  600  into a different aperture the height of the pod clamp frame will be changed. Although described as varying the height of the pod clamp frame by using a series of apertures on the clamp connector devices  516 , it should be appreciated that any suitable method may be used for varying the height of the pod clamp frame  510  including, but not limited to, a series of apertures on the receiving members  508 , a series of apertures on both the receiving members  508  and the clamp connector devices  516 , a telescoping clamp connector device using a hydraulic or mechanical lift, and the like. 
     In yet another embodiment, the hold down members  550  may be configured to engage the sides rather than the upper facing surface of the upper pod  200 , as shown in  FIG. 7C . In this embodiment, a portion of the inner wall  548  and the sides of the hold down members  550  may be used to prevent the upper pod  200  from moving in the direction parallel to the base  302 , or horizontal direction. An upper clamp frame  700  may be used to hold down the upper pod  200 . To this end the upper clamp frame  700  may be sized to have a height to match a particular model of pod. Further, when the upper clamp frame  700  is not being used to guide and/or hold down the upper pod  200  it may be used as a gripping point for manipulating and/or lifting the pod clamp frame  510 . 
     In yet another alternative embodiment, the upper pod  200  may not rest directly on the base  302  but may be secured to a separate device. For example, the upper pod  200  may be secured to the base between the pod clamp frame  510  and the upper clamp frame  700 . In this embodiment, the pod clamp frame  510  and the upper clamp frame  700  may have any suitable shape for securing the pod between the frames  510  and  700 . 
     In yet another embodiment, as shown in  FIG. 7D , the upper pod  200  may include a lip portion  702 . The lip portion  702  may extend beyond the main portion of the upper pod. In this embodiment, when the upper pod  200  is resting on the base  302 , the lip portion  702  may engage, or be proximate a top side  704  of the pod clamp frame  510 . The upper clamp frame  700  may then be secured over the lip portion  702 . The upper clamp frame  700  may secure the lip portion  702  and thereby the upper pod  200  in the base  302 . It should be appreciated that any of the components engaging the upper pod  200  may include a shock absorbing member and/or dampening member. 
     In yet another alternative embodiment, the pod clamp frame  510 , and/or the upper clamp frame  700  may be integral with the lifting cage  300 . In this embodiment, the pod(s) would be secured to the base  302  when the lifting cage  300  is engaged to the base  302 . 
       FIG. 8  depicts a schematic view of an offshore rig  800  having a drilling rig  802 , a drill string  804  and the subsea control package  114 , and/or pods  202  and  204 . During operation of the drilling rig  802 , the pods  114 ,  200  and/or  202  may need to be replaced. One or more new pods may be delivered to the offshore platform  800  using a vessel  806 . The pod(s)  114 ,  200  and/or  202  are typically loaded onto the base  302  in a warehouse, or factory. The lifting cage  300  may then be lowered over the base  302  and locked to the base  302 . The container  120  may then be transported to the vessel  806 . The vessel  806  may sail, or travel, to the offshore platform  800 . Each of the containers  120  may then be offloaded from the vessel  806  to the offshore platform  800  using the hoisting device  808 , or crane. The hoisting device may be attached to the offshore platform  800  or the vessel  806 . The lifting cage  300  may then be unlocked from the base  302  and the pod(s)  114 ,  200 , and/or  202  may be removed from the container  120 . The container  120  may prevent the pods from being damaged during the transportation process. 
     The container  120  may have a minimum design temperature of 4 degrees F. (−20 degrees C.). The empty weight of the container  100  may be 2500 lbs in some embodiments. The total shipping weight with the pods and the container  120  may be 15,000 lbs in some embodiments. The container  100  may be certified under DnV rules for offshore containers. The container  100  may have an offshore coating system (3 coat, 2-part epoxy, zonc primer).
