Description

TITLE: PIVOTING PIPE HANDLER FOR TENDER ASSISTED DRILLING RIGS
INVENTOR: Andrew Virgil Gerber CROSS REFERENCE TO RELATED APPLICATIONS:

[001] This application claims priority of U.S. provisional patent application serial no.
61/328,425 filed April 27, 2010.

TECHNICAL FIELD:

[002] The present disclosure is related to the field of pipe handlers, in particular, pipe handlers for tender assisted drilling rigs.

BACKGROUND:

[003] It is known to use pipe handlers on land-based drilling rigs. The pipe handler described in US patent application 2006/0285941 is a land rig type handler and shows the use of a pipe carrier to extend over the drill rig floor to deliver and receive tubulars or sections of drill pipe to the well bore, however, the system in whole is designed for a land rig, and is not suitable for use on a tender assisted drilling rig ("TAD"); it is designed to be loaded from horizontal pipe racks instead of from a high-line.

[004] There are other similar systems to US 2006/0285941 available commercially, which are also designed to be loaded in the same fashion. The pipe handler described in US Patent No. 7228919, and in US application no. 2007/0240884 has a stationary horizontal V-door with a pivotally mounted section designed to deliver single tubulars vertically to a stand building device. It is not adapted to deliver tubulars horizontally over the drill rig floor by mechanical means to the pick-up elevators. It also does not pivot to receive a bundle of multiple tubulars from the high-line at an inclined angle.

(E5991483.DOC;1) [005] US application no. 2009/0136326 describes a system that can move tubulars directly from the tender vessel to the vertical orientation in the mast of the drilling rig derrick directly in line with the well bore. This system bypasses the V-door entirely in its movement and operation, however, since by design it can only move a single tubular at a time between the tubular storage location on the tender vessel and the rig, it directly links the horizontal pipe handling to the critical path of rig operations when running in or pulling pipe out of the well bore. It does not have the tubular storage or staging capability of a V-door that allows rig operations to be not critically dependent on the horizontal tubular movement operations to or from the tender vessel.

[006] It is, therefore, desirable to provide a pipe handler that overcomes the shortcomings in the prior art for use on tender assisted drilling rigs.

SUMMARY:

[007] A pivoting pipe handler for tender assisted drilling rigs is provided.
In one embodiment, the pipe handler can comprise an entire V-door that is pivotally mounted, powered and controlled by electromechanical means whereby the V-door can be inclined at a predetermined angle to receive bundles of tubulars from a high-line mechanism that transports the tubulars from a tender vessel to the pipe handler. The V-door can then rotate upwards to a substantially horizontal position to facilitate a safer orientation and position for the manual work in disconnecting and unbundled the tubular payload. The V-door angle can be adjusted for optimal delivery and retrieval of tubulars to the pick up elevators at the well bore. In another embodiment, the V-door can comprise a pipe carrier, which can be powered to cantilever over the drill rig floor to the optimal working position for latching or unlatching the pick up elevators on the tubulars.

{E5991483.DOC;1}

In another embodiment, the V-door can comprise pipe handling devices that can push the tubulars off of the pipe carrier, or at one at a time onto the carrier to facilitate pick up and lay down operations. All of the devices can be electrically powered and controlled from a remote operator station at a safe vantage point. The V-door can also comprise a walkway along its length to provide an operator with a safe walking space when performing the manual functions connecting or disconnecting the tubular payload from the high-line.

[008] In some embodiments, a pipe handler is provided for a tender assisted drilling rig comprising an elevated drilling rig floor and an adjacent lower platform, the pipe handler comprising: a main support structure having upper and lower ends, the upper end configured to operatively coupled to the drilling rig near the drilling rig floor, the lower end configured to operatively couple to the lower platform wherein the main support structure is disposed at an incline thereto; a V-door operatively coupled to the main support structure, the V-door comprising an upper end pivotally attached to the upper end of the main support structure; means for elevating the lower end of the V-door operatively disposed between the main support structure and the V-door; and a pipe carrier slidably disposed on the V-door, the pipe carrier configured to extend from a seated position to an extended position that places the pipe carrier nearer the drilling rig floor.

[009] In some embodiments, a method is provided for handling tubulars on a tender assisted drilling rig comprising an elevated drilling rig floor and an adjacent lower platform, the method comprising the steps of: providing the pipe handler of claim 1 disposed between the drilling rig floor and the lower platform; delivering a plurality of (E5991483.DOC;1 }

tubulars to the pipe handler from a tender vessel using a high-line mechanism and placing the tubulars in a storage area on a V-door disposed on the pipe handler; moving the V-door to a substantially horizontal position relative to the drilling rig floor; indexing one tubular onto a pipe carrier slidably disposed on the V-door; extending the pipe carrier towards the drilling rig floor; and pushing the tubular along the pipe carrier further towards the drilling rig floor with a skate slidably disposed on the pipe carrier wherein the tubular can be presented for connection with a drill string.

DETAILED DESCRIPTION OF EMBODIMENTS

[0025] A pivoting pipe handler for tender assisted drilling rigs is provided.
Referring to Figure 1, pivoting pipe handler 25 is shown disposed on drilling rig 30 at an incline between drilling rig floor 32 and lower platform 36. In this illustration, tubulars 34 are being delivered to pipe handler 25 from a tender (not shown) using high-line mechanism 13, which is a well-known mechanism to those skilled in the art.

[0026] Referring to Figure 2, one embodiment of pipe handler 25 is shown with V-door 2 in a horizontal position. In this embodiment, pipe handler 25 can comprise main support structure 1 further comprising V-door 2 pivotally attached to the upper end of main {E5991483. DOC;1 }

support structure 1. Lower end 38 of V-door 2 can be raised with an elevating mechanism or means for elevating lower end 38. In some embodiments, the elevating mechanism can comprise lift arm 7 pivotally attaching at an upper end thereof to V-door 2, and a lower end thereof slidably disposed on main support structure 1, as well known to those skilled in the art. In some embodiments, the lower end of lift arm 7 can be slidably disposed in roller channels 14 disposed on main support structure 1.
In this embodiment, lift arm 7 can comprise horizontal crosshead 9 having rollers disposed in roller channels 14. Crosshead 9 can further comprise roller screw nut disposed thereon for receiving roller screw 6 that, in turn, is operatively coupled to motor 10 disposed at a lower end of main support structure 1. When motor 10 operates, roller screw 6 can turn clockwise or counter-clockwise, depending on whether lower end 38 of V-door 2 is to be raised or lowered. When lower end 38 is to be raised, motor 10 is operated to turn roller screw 6 in the direction that causes the lower end of lift arm 7 to move upwards in roller channels 14. In so doing, the upper end of lift arm 7 raises causing lower end 38 of V-door 2 to pivot upwards until V-door 2 is in a substantially horizontal position. To lower V-door 2, motor 10 is operated in the opposite direction to cause the lower end of lift arm 7 to move downwards along roller channels 14 until V-door 2 is seated within main support structure 1. It is obvious to those skilled in the art that other suitable and equivalent mechanism can be used to elevate and lower lower end 38 of V-door 2.

[0027] In other embodiments, motor 10 can be operated with reducer 12 to lower the rotational speed of motor 10, which can also have the effect of increasing the torque applied to roller screw 6 by motor 10. Couplers 11 can also be used to couple motor 10 to reducer 12, and to couple reducer 12 to roller screw 6.

{E5991483.DOC;1 }

[0028] In this illustrated embodiment, the lower end of main support structure 1 can be coupled to lower platform 36 with coupling tabs 21. In other embodiments, pipe handler 25 can comprise stairwell 16 to allow personnel to move between drilling rig floor 32 and lower platform 36. Pipe handler 25 can also comprise walkway 15 disposed on V-door to allow personnel to move along V-door 2 when it is in a substantially horizontal position.

[0029] In this illustrated embodiment, V-door 2 can further comprise pipe carrier 3 that can be slidably disposed on V-door 2 such that it can slidably extend from V-door 2 towards drilling rig floor 32. In other embodiments pipe carrier 3 can also comprise skate 4 slidably disposed thereon. Skate 4 can further slide along pipe carrier 3. V-door 2 can also comprise pipe indexers 5 that can move or "index" tubulars from storage area 40 on V-door 2 onto pipe carrier 3. In some embodiments, V-door 2 can comprise two or more pipe indexers 5 disposed on the off-driller side of V-door 2. In some embodiments, V-door 2 can further comprise two or more kicker mechanisms disposed on the on-driller side of V-door 2.

[0030] Referring to Figure 3, V-door 2 of pipe handler 25 is shown in an inclined position. Referring to Figure 4, V-door 2 has been elevated by lift arm 7 so that V-door 2 is now in a substantially horizontal position. Referring to Figure 5, pipe carrier 3 has been extended from V-door 2 towards drilling rig floor 32.

[0031] Referring to Figure 6, a top view of pipe handler 25 is shown. In this figure, V-door 2 is in a substantially horizontal position with tubular 34 positioned on pipe carrier 3, which is shown in a retracted position on V-door 2. A plurality of tubulars 34 are also shown in storage area 40.

{E5991483.DOC;1 }

[0032] Referring to Figure 7, a tubular 34 is shown sifting on elongate indentation 20 disposed on the top surface of pipe carrier 3. A plurality of tubulars 34 are also shown sitting on inclined surface 19 of storage area 40 of V-door 2.

[0033] In one embodiment, a tubular can be ejected from the pipe carrier.
Referring to Figure 8, a tubular 34 is shown being ejected from pipe carrier 3 onto inclined surface 19 by pipe kicker arm 17 that can be extended from kicker mechanism 44. Kicker arm 17 can further comprise kicker roller 22 that can roll on top of pipe carrier 3. In another embodiment, kicker arm 17 can pivot about pivot point 23.

[0034] In another embodiment, a tubular can be indexed onto the pipe carrier.
Referring to Figure 9, a tubular 34 is pushed, or "indexed", onto trough 20 disposed on pipe carrier 3 by pipe indexer 5 pushing tubulars 34 up inclined surface 19 until a tubular 34 is seated in trough 20 on pipe carrier 3.

[0035] In operation, and referring to Figures 1 to 9, tubulars 34 can be delivered to pipe handler 25 from a tender vessel (not shown) using high-line mechanism 13.
Tubulars 34 delivered to pipe handler 25 can be placed in storage area 40 of V-door 2.
Tubulars 34 can then be presented to drilling rig floor 32 by raising V-door 2 to a substantially horizontal position, indexing a tubular 34 onto pipe carrier 3 with pipe indexer 5, extending pipe carrier 3 towards drilling rig floor 32 and pushing tubular 34 along pipe carrier 3 with skate 4 further towards drilling rig floor 32 so that the tubular 34 can be tripped into the drill string as well known to those skilled in the art. This operation can be reversed to trip tubulars 34 out of the drill string by placing tubulars 34 on extended pipe carrier 3, retracting pipe carrier 3 into V-door 2 and ejecting tubulars 34 off of pipe carrier 3 with kicker 17 towards storage area 40. Lower end 38 of V-door 2 can then be {E5991483.DOC;1}

lowered to the inclined position so that tubulars 38 can be delivered to the tender vessel using high-line mechanism 13.

As kicker drive belt 54 is moved clockwise or counter clockwise by motor 62 operating drive pulley 56, kicker arm 17 can be extended from or retracted into kicker mechanism 44, respectively. Referring to Figure 11, kicker arm 17 is shown being extended from kicker mechanism 44 to push tubular 34 from trough 20 onto inclined surface 19. Referring to Figure 12, kicker arm 17 has been retracted into kicker mechanism 44 and tubular 34 is disposed on inclined surface 19.

[0037] In some embodiments, indexer 5 can comprise push block 46 operatively coupled to attachment plate 51 that can extend through slot 49 and attach or clamp to drive belt 48. In some embodiments, push block 46 can extend through slot 45.
Push block 46 can further comprise guide block 72 slidably disposed on guide shaft or rail 68 wherein push block 46 can move along inclined surface 19 as guide block 72 moves {E5991483.DOC;1) along guide shaft or rail 68. Indexer drive belt 48 can pass over idler pulleys 52 and be driven by drive pulley 50. Drive pulley 50 can be operated by indexer drive motor 64, as shown in Figures 11 to 13. As indexer drive belt 48 is moved counter clockwise or clockwise by motor 64 operating drive pulley 50, push block 46 can be moved towards or from trough 20, respectively. Referring to Figure 13, push block 46 is illustrated pushing tubular 34 up inclined surface 19 towards trough 20 wherein tubular 34 can be pushed or "indexed" into trough 20. In some embodiments, indexer 5 and kicker mechanism 44 can comprise some or all of the elements of the indexer/kicker disclosed in International Patent Application No. PCT/CA2010/001186 having International Publication Number WO 2011/011887 Al, which was published on 3 February 2011.

[0039] Referring to Figure 15, one embodiment of the mechanism that can be used for operating skate 4 on pipe carrier 3 is illustrated. In some embodiments, the operating mechanism for skate 4 can comprise gear motor 108 operatively disposed within pipe carrier 3. Gear motor 108 can rotate drive sprocket 106 that can, in turn, rotate drum sprocket 102 and capstan drum 100 via chain 104. Capstan drum 100 can reel in and out wire rope 110 that can pass over idler sheave 98 disposed near pipe roller 76, and can further pass over idler sheave and tensioner 112 and attach to skate rudder 116 via open spelter sockets 114 disposed thereon. Upon operation of gear motor 108, wire rope 110 can pull skate 4 along skate slot 118 disposed on trough 20 to push pipe or tubulars along pipe carrier 3.
