       BACKGROUND OF THE INVENTION 
       [0005]    1. Field of the Invention 
         [0006]    The present invention relates to cargo racks for transferring goods between marine vessels and offshore platforms such as oil and gas well drilling and production platforms. More particularly, the present invention relates to an improved cargo rack that enables a user to load the rack with multiple load modules (e.g. fluid containing vessels or tanks), palletized loads, bulk bags (or other loads) and to then transport the entire rack using a lifting device such as a crane or a forklift from one locale (e.g. marine vessel) to another locale (e.g. marine platform). Additionally, the entire rack can be moved on land or on the platform with a crane or forklift. When supporting fluid holding vessels or tanks, a specially configured manifold can be used to empty a particular or selected tank or vessel. Lifting fittings are placed at the top of intermediate columns and inner reinforcement members (e.g. inner braces or walls) transfer load from one intermediate column to another intermediate column. 
         [0007]    2. General Background 
         [0008]    In the exploration of oil and gas in a marine environment, fixed, semi submersible, jack up, and other offshore marine platforms are used during drilling operations. Fixed platforms are typically used for production of oil and gas from wells after they have been drilled. Drilling and production require that an enormous amount of supplies be transported from land based storage facilities. Supplies are typically transferred to offshore platforms using very large marine vessels called work boats. These work boats can be in excess of one hundred feet (30.48 meters) in length and have expansive deck areas for carrying cargo that is destined for an offshore platform. Supplies are typically transferred from a land based dock area to the marine vessel using a lifting device such as a crane or a mobile lifting and transport device such as a forklift Once a work boat arrives at a selected offshore platform, supplies or products are typically transferred from the deck of the work boat to the platform using a lifting device such as a crane. 
         [0009]    Once on the deck of a drilling platform or production platform, space is at a premium. The storage of supplies on an offshore oil well drilling or production platform is a huge problem. 
         [0010]    Many cargo transport and lifting devices have been patented. The table below lists some patents that relate generally to pallets, palletized racks, and other cargo racks.

Similarly sized and shaped openings are provided on body or block  60  so that a bolted connection can be formed using bolt  75  and a nut  79  as shown in  FIGS. 12 and 13 . 
         [0066]    The annular grooves  70  of pin  69  register in slots  77  end plates  71 ,  72  as shown in  FIG. 12 . Each of the slots  77  communicates with a circular opening  76  that is slightly larger than the diameter of the pin  69 . In this fashion, the pin  69  can pass through the openings  76  of the plates  71 ,  72 . The pin  69  is too large to occupy the recess or slot  77 . However, each annular groove  70  at an end portion of the pin  69  is sized and shaped to enable the pin  69  to interlock with the plates  71 ,  72 . The annual grooves  70  enable this fit of pin  69  to the plate  71  or  72  at the slot  77  as shown in  FIG. 13 . 
         [0067]    A cover plate  78  can be placed over the block or body  60 , the plate  78  being receptive of the bottom  15  of another rack  10  when they are stacked upon one another as shown in  FIG. 16 . A lifting line or sling  80  has an eyelet  81  which can be rigged to the pin  69  as shown in  FIG. 13 . When a crane or other implement lifts upwardly on the slings  80 , each sling  80  eyelet  81  transfers load to the pin  69  and thus to the lifting assembly  54 ,  55 ,  56 ,  57  and thus to the frame  11 .  FIG. 11  illustrates a lifting implement or hook or crown block  82  that is commonly employed in combination with a lifting device such as a crane. Other lifting fitting such as a ring or shackle  83  can be employed as an interface between the slings  80  and the lifting implement  82 . 
         [0068]      FIG. 6  illustrates a manifold or header  84  that can be used to transfer fluid from any one of the load modules or tanks  105  and a discharge or outlet fitting or coupling  91 . Header or manifold  84  is contained within base  11  interior  85 . The base  11  has a bottom panel  86 . A pair of beams or channels  87 ,  88  extend through base  11 , each providing an opening or bore  89 ,  90  that is receptive of a forklift tine. In this fashion, the frame  11  can be lifted using a forklift by engaging the forklift tines in the bores  89 ,  90  of the beams or channels  87 ,  88 . 
         [0069]    Valve  92  having valve handle  93  can be placed immediately upstream of discharge of outlet fitting or coupling  91 . Header  84  communicates with valve  92 . A plurality of four flow lines  94 ,  95 ,  96 ,  97  empty their contents into header  84  as shown in  FIG. 6 . Each of the flow lines  94 ,  95 ,  96 ,  97  attaches to a different one of the tanks or modules  105 . A detail of the fluid connection between a tank or module  105  and header  85  can be seen in  FIG. 10 .  FIG. 10  illustrates the connection of a single flow line  94  to a tank  105 . It should be understood that each of the flow lines  94 ,  95 ,  96 ,  97  can be similarly connected to a tank or module. 
         [0070]    Flow line  94  connects to swivel  98 . The swivel  98  connects to a riser  99  at elbow fitting  100 . Another elbow fitting  101  connects to hose section  102 . Hose section  102  is provided with a quick connect fitting  103  that forms a quick connect with a flow line  106  that exits the tank or module  105 . This connected position can be seen in  FIG. 11 . In  FIG. 11 , a tank discharge flow line  106  is shown which can be provided with a tank discharge valve  107 . Tank discharge flow line  106  can be provided with a quick connect that forms a connection with the quick connect fitting  103  of  FIG. 10 . The swivel  98  enables movement of the quick connect fitting  103  as shown by arrows  104  in  FIG. 10 . 
         [0071]    Each corner column  29 - 32  can be provided with a stacking fitting  110  which enables one cargo rack  10  to be stacked upon another cargo tank  10  as seen in  FIG. 16 .

Each stacking fitting  110  provides a horizontal and preferably rectangular plate  112  and two vertical plates  113 ,  114  which intersect at right angles and which extend upwardly from the periphery of plate  112 . 
         [0072]    Module receptacles  115  are provided for supporting each corner of a tank or module  105 . Each receptacle  115  has a lower plate  116  and side, vertical plates  117 ,  118  as seen in  FIGS. 1-5 ,  11 , and  16 . Each tank or module  105  has four feet  119 , each foot  119  registering upon a module receptacle  115  as seen in  FIG. 11 . 
         [0073]    A drain is provided for draining fluids from floor  16  such as might occur during a wash down or if there is leakage from one of the modules  105 . Drain channel  121  is mounted just under floor  16  as seen in  FIGS. 7-8 . Drain channel  121  has flow bore  122 . A plurality of floor openings  123  are provided, such as one of the openings  123  under each opening  120  as shown in  FIG. 8 . Drain channel inlet openings  124  are ports or openings in the channel  121  and are aligned with the floor openings  123 . Arrows  125  in  FIG. 8  illustrate the flow path of fluid that drains from floor  116  to channel  121  bore  122 . Fluid received in channel  121  flows via gravity to drain pipe  126 . Pipe  126  is closed at one end portion with cap  127 . The other end portion of pipe  126  is fitted with valve  129 . In  FIG. 8 , arrow  128  illustrates flow direction of fluid in pipe  126 . 
         [0074]      FIGS. 17-23  illustrate the doors  21 - 24  and the mechanism for opening or closing a door. While doors  21 - 22  are shown in  FIGS. 17-23 , the same configuration could be used for doors  23 - 24 . Each door  21 ,  22  has a pair of vertical members. The door  21  has vertical members  130 ,  131 . The door  22  has vertical members  132 ,  133 . Horizontal members span between the vertical members of each door  21 ,  22  as shown. The door  21  has horizontal members  134  that span between vertical members  130 ,  131 . Similarly, horizontal members  135  span between the vertical members  132 ,  133  of the door  22 . The innermost vertical members  131 ,  133  are an assembly that includes vertical flanged members  140 ,  141 , rods  138 ,  139 , sleeves  142 ,  143  and other plates and guides that will be described more fully hereinafter. 
         [0075]    Each door  21 ,  22  can be opened or closed using levers  153 ,  154  which are attached to the rods  138 ,  139 . Each rod  138 ,  139  is mounted in a sleeve and in rod guides. The rod  138  is able to move up and down while being supported by sleeve  142 , upper rod guide  144 , lower rod guide  146  while being moved up or down with a lever  153 . In  FIG. 17  there are two rods  138  associated with the door  21 . It should be understood, that the door  21  as constructed can be used when inverted such as if for replacing one of the other doors. 
         [0076]    Similarly, the door  22  has two rods  139 , each rod having an attached lever  154 . The rod  139  is supported by upper rod guides  145 , lower rod guides  147  and sleeve  143 . Each of the rod guides  144 ,  145 ,  146 ,  147  provides a rod opening  148  through which a rod  138  or  139  can pass. An upper plate  136  and a lower plate  149  are provided for locking a gate  21 ,  22  in a closed position when a rod  138 ,  139  is moved upwardly using a lever  153  or  154 . In  FIG. 17 , all of the rods  138 ,  139  are in an open position.  FIGS. 23 and 23  illustrate a movement of lever  153  from the open position of  FIG. 17  to the closed position. In  FIG. 23 , the lever  153  is shown being moved to the closed position as indicated by arrows  161 ,  162 .
