  • SHEET 8 OF 6 BACKING BOARD BACKGROUND OF THE INVENTION In well drilling operations it is necessary to handle lengths of pipe or conduit in a derrick in a rapid and efficient manner. For example, when drilling wells by the rotary drilling method, it is necessary to remove and replace the drill stem into the bore hole a number of times during the course of the drilling operation.
  • the drill stem' is made up of lengths of pipe with the ends fastened together by threaded joints.
  • the disconnected stand is raised and moved over to one side of the derrick where it is racked with its axis substantially vertical.
  • the drill stem is then raised until another stand of pipe is above the derrick floor.
  • the reverse pro cedure is used with the pipe taken from its racked position a stand at a time.
  • the stand is moved from the rack with its axis substantially vertical until its axis coincides with that of the well hole.
  • the lower end of the stand is then connected with the portion of the drill stem in the hole, and the drill stem is lowered until the upper end of the last connected stand is just above the derrick floor and the operation repeated.
  • Offshore drilling operations whether conducted from a semisubmersible platform'or a floating drilling vessel, present additional problems to those described above in that theaction of the sea causing the platform and derrick to pitch and roll makes the provision of a satisfactory apparatus for handling pipe essential.
  • down-time i.e., the time in which drilling operations must be suspended by reason of weather or sea conditions, is an important factor in the total cost of the well being drilled.
  • safety considerations are involved to an extent not present in most land-drilling operations.
  • Pipe racking apparatus of the type known to the prior art are not fully satisfactory for offshore drilling opera tions nor for offshore or land drilling operations Where harsh climatic conditions prevail. It can readily be seen that when large amounts of heavy pipe are stacked vertically in a derrick where the platform upon which the pipe rests is somewhat unstable, hazards to personnel and the equipment are presented. The present invention eliminates those hazards and makes the type of operation described above more efficient and safe. By allowing a completely safe operation, the drilling operations can be carried out under circumstances of weather and sea conditions, for example, at which they would otherwise have to be terminated and in this manner the use of the pipe racking apparatus of the present invention maximizes the amount of time during which drilling operations can be performed by the drilling equipment in conjunction with which the present invention is utilized.
  • the present invention is so constructed that the parts which are required to move are of heavy mass and are driven by relatively strong forces so that any ice formed thereon can be readily broken away by the operation of the equipment itself.
  • the present invention provides an improved racking apparatus for vertically racking oil well pipe, the apparatus being suitable for the racking of pipe on unstable platforms such as a floating drilling vessel or a semisubmersible platform but also being applicable to the racking of pipe on a stable offshore platform or land rig.
  • the present invention is also adaptable to receiving different sizes of pipe which may be racked simultaneously.
  • Another object of the present invention is to provide a pipe racking apparatus which may be readily adapted to partial or fully automated drilling operations.
  • Drilling pipe apparatus for use on drilling rigs for controllably engaging and retaining a plurality of stands of pipe adjacent to the tops thereof for racking purposes.
  • the system is comprised of a generally horizontally oriented frame assembly, disposed above the floor of the drill rig, with the frame assembly supporting a plurality of slideable racking arms therein.
  • the racking arms are provided with a plurality of spaced protrusions which define open racking cells on one side of the racking arm, with the protrusions defining the racking cells slideably engaging the adjacent side of the next racking arm to define the closed cells.
  • a system of pneumatic or hydraulic cylinders or other suitable driving means is ap proximately controlled through an electrical system by solenoid valves, to provide for the electrically-. controlled selective'sliding of each racking arm so as to open and close the racking cells in an adjacent racking arm in an orderly progression.
  • Safety relays appropriately disposed provide an interlock for the solenoid valves so as to insure that positive engagement with each racking arm is provided at all times to that the racking arms are never free to randomly slide and inadvertently release the pipe racked therein. Upon full exgressively receiving stands of pipe.

  • the console is of conventional construction, providing electrical signals to solenoid valves controlling the flow of hydraulic fluid to the various hydraulic cylinders and air to the various air cylinders in the apparatus herethfore described so as to result in the desired motion and locking of the racking arms. It is to be noted, however, that if both pins 22 and 27 (FIG. 4) for any of the racking arms 68 were simultaneously withdrawn, the corresponding racking arm would be free to slide in a longitudinal direction, thereby opening the racking cells in an adjacent racking arm, releasing the pipe stands stored therein. To prevent such an occurrence.
  • the locking pins 22 and 27 are spring loaded in the locked position and can be withdrawn by engaging switches which control the solenoid valve which control the cylinders 45 and 21 respectively. Note, however, that the solenoid valves are connected so that only one cylinder, 21 or 45, can be withdrawn. at any time, i.e., if one is withdrawn, the other is engaged. Thus, neither pin 22 nor pin 27 for any racking arm may be withdrawn unless the other pin is in the extended position, thereby assuring that each racking arm is engaged at all times by at least one of pins 22 or 27.
  • pin 22 is preferably generally encouraged, in event of any power failure, to the engaged state due to the spring loaded position and is only withdrawn by application of pneumatic pressure, so that all racking arms are locked in the event the pneumatic system is deactivated or fails to properly function.

  • a system of hydraulic main cylinders and pneumatic secondary cylinders has been found particularly useful.
  • One such system not shown in the present embodiment is described below. It uses a long stroke horizontal hydrualic cylinder. The total stroke of the cylinder is equal to the maximum travel of the sliding racking arm. As the racking arm 68 must move only a fraction of its travel per pipe stand 40 stored, the travel of the cylinder must be interrupted for each pipe stand 40.
  • the cylinder can then be started and stopped by direct manual control. This system can only be applied where the operator is sufficiently close to the racking system, to see what he is doing.
