       BACKGROUND 
       [0004]    Abandonment Procedure for Wells on a Platform That Has Fallen over. There are basically two ways to restore control of the wells on a platform that has fallen over. Abandon the wells completely in the order they are accessed, or remove the bent or broken portion of the well and install a subsea wellhead. However, when removing the bent or broken part of the pipe such piping may still be under pressure such pressure dealt with before removal. Otherwise, a blow out could occur. 
         [0005]    The present invention relates to the cutting of multiple nested (e.g., coaxial) strings of underwater piping and/or tubing for overturned wells and/or platforms using a specially configured articulating drill apparatus and method. 
         [0006]    Under pressure drilling or hot tapping is the process of drilling into a pressured pipe or vessel using special equipment and procedures to ensure that the pressure and fluids are safely contained when access is made. The most common example of a hot tap is into a pressured pipeline.

     DETAILED DESCRIPTION 
       [0075]      FIG. 1  shows a damaged marine platform  1 . The platform  1  can be any offshore or marine platform such as a drilling platform, production platform or the like. Such a platform is normally supported by an underwater jacket  4  that is anchored to seabed  2 . 
         [0076]    When a fierce storm such as a hurricane strikes, the upper  5  can be separated from jacket  4  by wind and wave action at water surface area  3 . Upper  5  can be any known above water upper such as drilling (e.g., derrick  7 ) or production structures having one or more decks  6 . When a hurricane separates upper  5  from jacket  4 , tubulars  50  can remain under pressure though bent at bends  8  as shown. Often, multiple nested tubulars are present. 
         [0077]    One embodiment includes an articulating drill system  1100  which can be used in the process of hot tapping a string of a plurality of pipes or tubing system. The plurality of pipes can include first pipe  50 , second pipe  60 , third pipe  70 , and fourth pipe or tubing  80 . Between first and second pipes is annular space  62 . Between second and third pipes is annular space  72 . Between third and fourth pipes is annular space  82  (see  FIGS. 9 and 10 ). 
         [0078]    In one embodiment articulating drill system can be used with a hot tap system  10 , which can include adjustable clamp  100  (see  FIGS. 2-24 ). In one embodiment hot tap system  10  can include a plate  200  and one or more chains  150 . In one embodiment adjustable clamp  100  can include first and second plates  200 ,  200 ′ and are threadably connected to each other and can be frictionally connected to a pipe. 
         [0079]      FIG. 2  is a perspective view illustrating the step of lowering a hot tap housing  100  (two plate embodiment) and a diver  9  attaching the housing to one of the riser piping systems (e.g. nested tubulars  50 ,  60 ,  70 ,  80 ) below the bend  8  in the riser  50 ,  60 ,  70 ,  80 .  FIG. 3  is a perspective view illustrating the step of the diver  9  tightening the hot tap housing  100  (two plate embodiment) below the bend in the riser.  FIG. 4  is a perspective view illustrating the step of lowering to a diver  9  (from a surface vessel, not shown) the hot tap tool  2000  along with a hot tap tip and housing which will be attached to the hot tap housing  100  for hot tapping one or more of the nested tubulars  50 ,  60 ,  70 ,  80 . 
         [0080]      FIG. 5  is a perspective view illustrating the step of a diver  9  hot tapping one or more of the nested tubulars  50 ,  60 ,  70 ,  80  where the hot tap tool is rotatively connected to the circular thrust/articulating plate at a selected rotational position. The one or more windows in the thrust plate allow the user (e.g. diver  9 ) to see the tip of the hot tap tool  2000  to obtain a good position between the hot tap tip and the nested tubular  50  or  60  or  70  or  80  being hot tapped. 
         [0081]      FIG. 6  is a closeup perspective view of hot tap tool  2000  after being connected to the hot tap housing  100 . 
         [0082]      FIG. 7  is a perspective view illustrating the step of lowering the articulating saw  1100  to a diver  9  for use in the hot tapping process. In  FIG. 8 , the diver  9  is shown attaching the articulating saw  1100  to the hot tap housing  100 . The saw  1100  can be pivotally attached to the hot tap housing  100  via a pin on one side and a support plate on another side. The saw  1100  also has an articulating and sliding support join for the rotating saw shaft.  FIG. 8  shows the saw  1100  attached to the hot tap housing  100  and positioned to make a cut in one of the nested tubulars  50 ,  60 ,  70 ,  80 .  FIG. 9  is a closeup perspective view of a diver  9  using the hot tap tool  2000 .  FIG. 8  is a perspective view of a diver  9  using the articulating saw  1100 . 
         [0083]    In one embodiment first plate  200  can comprise first side  210 , second side  220 , a main opening  230 , and a plurality of openings  240  for supporting a compression plate. Main opening  230  is designed to allow access through first plate  200  (from first side  210  and through second side  220 ) (see  FIGS. 2-24 ). 
         [0084]    Between the steps of hot tapping nested tubulars, drill system  1100  can be swung (e.g., pivoted on pin  294 ) out of the way so that diver  9  can use hot tapping tool  200  without drill system  1100  being in the way. Also between steps of hot tapping nested tubulars, articulating drill system  1100  can remain attached to outside pipe  50  (e.g., by being pivotally attached to pin  294  of hot tap clamp  100  which is connected to pipe  50 ). 
         [0085]    In  FIGS. 14-24  and  35 - 45 , one embodiment articulating drill system  1100  can include first arm  1110 , second arm  1120 , base  1150 , and connection plate  1500 . First arM  1110  can be pivotally connected to second arm  1120 . Second arm  1120  can be pivotally connected to base  1150 . Base  1150  can be pivotally connected to connection plate  1500 . 
         [0086]    Drill  1300  can be attached to base  1150 . Drill  1300  can comprise motor  1320  and cutting tip  1400  which is rotationally connected to motor  1320 . 
         [0087]    Longitudinal track system  1160  can allow controlled longitudinal movement (e.g., along the longitudinal direction of base  1150 ) of drill  1300  such as by a screw and thread system. Track system  1160  can include a quick release/quick lock system which longitudinally locks the position of drill  1300  relative to base  1150 . 
         [0088]    Perpendicular track system  1200  can allow controlled perpendicular movement (e.g., perpendicular to the longitudinal direction of base  1150 ) of drill  1300  such as by a screw and thread system. Track system  1200  can include a quick release/quick lock system which perpendicularly locks the position of drill  1300  relative to base  1150 . 
         [0089]    Longitudinal and perpendicular track systems  1160  and  1200  can respectively longitudinally and perpendicularly adjust the position of drill  1300  and tip  1400 . 
         [0090]    Drill system  1100  can be pivotally connected to first plate  200 , such as by pin  294 . 
         [0091]    Connection plate  1500  can be used to partially positionally lock drill system  1100  relative to first plate  200 . Even when partially locked, drill  1300  can be pivoted relative to first plate  200  through pivoting joint  1510 . Quick release/quick lock  1550  when unlocked allows for pivoting. However, locking quick release/quick lock  1550  prevents further pivoting movement of drill  1300 .

Housing section  132  slides upon rear surface  136  of plate  111 . In this fashion, a user such as diver  9  can loosen bolts or clamps  121 ,  122  and slide the housing sections  117 ,  125  laterally relative to plate  111 . The plate  111  can be bolted to a selected part of clamp  100  using bolted connections at plate openings  112 ,  113 . The housing section  125  has internally threaded openings  126 ,  127  that accept threaded portions  138  or  139  of bolts  121  or  122 .
