1. Field of the Invention
The present invention relates to pipe handling systems used in drilling wells on land or offshore.
2. Description of the Related Art
A tubular to be used in drilling is typically first lifted with a crane from a horizontal pipe storage rack located in the pipe deck area outside the drilling structure or derrick on the drilling deck, and then placed horizontally with one end of the tubular near the V-door of the derrick. The tubular may then be moved through the V-door with rig equipment and rotated into the vertical position for either stand building or direct insertion through the well center. The traditional tubular handling process is inefficient and raises safety issues.
Although several horizontal pipe handling systems have been proposed, they rely upon various mechanical pipe moving devices to move a pipe from the top of a pipe rack. U.S. Pat. No. 3,734,210 proposes a pipe transfer assembly having a support arm with a pipe flipper operated with an air cylinder to engage a pipe at the top of a rack and release and push it to a handling arm. Pub. No. US 2008/0101891 proposes a pipe rack with a lifting block mechanism that lifts a pipe over an elevated stop mechanism for it to move to a motorized arm mechanism that rotates and lowers the pipe to an adjacent erector system. Pub. No. US 2007/0031215 proposes a vertically moveable pipe moving assembly with an extendable finger that lifts a tubular over the top of a pipe rack and allows it to move to an attached rotatable arm for movement with the pipe moving assembly vertically down the side of the pipe rack where the rotatable arm rotates to move the pipe to an erector system. U.S. Pat. No. 6,311,788 proposes a vertically moveable pipe removal device with an extendable and rotatable gripping claw to lift and remove a drilling rod part from a drilling rod magazine. U.S. Pat. No. 7,537,424 proposes a pivotable and extendable pipe transfer arm to lift and remove a pipe section from a pipe storage bin. U.S. Pat. No. 6,860,694 proposes a picking column with picking arms to lift and remove a pipe from the top of a pipe rack. Pub. No. US 2003/0196791 proposes a vertical conveyor system with shovel arms that lift and remove a pipe from the top of a pipe rack and transports the pipe up to a series of horizontal conveyor systems.
Pub. No. US 2008/0202812 proposes a pipe rack that preferably stores five tubulars that has a hydraulically operated indexing arm assembly that rolls the tubulars toward a pick up location and hydraulically activated separators isolate one tubular that is to be gripped by a horizontal to vertical arm (see '812 publication ¶60).
The above discussed U.S. Pat. Nos. 3,734,210; 6,311,788; 6,860,694; and 7,537,424; and Pub. Nos. US 2003/0196791; 2007/0031215; 2008/0101891; and 2008/0202812 are hereby incorporated by reference for all purposes in their entirety.
Handling numerous heavy tubulars of different sizes in severe drilling environments is known to be challenging for and destructive to mechanical devices. Valuable rig time is lost when the mechanical devices require maintenance and/or repair. A need exists for a pipe handling system that minimizes mechanical devices that require maintenance and/or repair. A need exists for a pipe handling system that may be safely operated with minimal human intervention while creating rig use efficiencies. It would also be desirable to be able to selectively handle tubulars from different tiers of a pipe rack, and to have a reliable way to move a tubular toward the well center.
A system and method are provided for a tubular handling system in which a cartridge of tubulars may be removably positioned with a carriage. The carriage may move the cartridge transversely, vertically, and/or rotationally. The carriage may be positioned adjacent to a tubular receiving member so as to either load tubulars onto the tubular receiving member, or to unload tubulars from the tubular receiving member. The carriage and the tubular receiving member may be disposed with a catwalk structure. Tubulars may be selectively handled from any tier of the cartridge. In one embodiment, a cartridge of tubulars may be positioned between two carriages. A single trolley disposed with the tubular receiving member may both push a tubular toward the well center or pull a tubular away from the well center on the drilling deck.
A better understanding of the present invention can be obtained with the following detailed descriptions of the various disclosed embodiments in the drawings:
The tubular handling system may be used in many different drilling environments, including the environment shown in
Cartridge 20 is removably mounted on first carriage 30A and second carriage 30B. A deck crane (not shown) may move any of the cartridges (10, 20) between the cartridge storage area and carriages (30A, 30B). It is contemplated that there may be a plurality of carriages, such as carriages (30A, 30B). Carriages (30A, 30B) are positioned adjacent to tubular receiving member 40. Both carriages (30A, 30B) and tubular receiving member 40 may be in an elevated catwalk area structure mounted near the end of the drill floor F, such as carriage support member 70 shown in FIGS. 3 and 5-9. However, other locations are contemplated. Returning to
Cartridges (10, 20) may be certified offshore lifting devices. Cartridges (10, 20) may hold single or multiple levels or tiers of tubulars. Cartridges (10, 20) may be handled by any suitable lifting device, such as a four leg lifting sling set and deck crane, a spreader beam assembly and deck crane, or a fork lift truck (onshore). As discussed above, cartridges (10, 20) may be stackable both on the rig pipe deck, on land or other area adjacent to the drilling deck to minimize space required for storage. Cartridges (10, 20) may store and load various sizes of tubulars. Cartridges (10, 20) may be transportable on trailers on land. It is also contemplated that the carriages (30A, 30B) may be used to handle tubulars that are not in a cartridge.
In
Carriage support member 70 also supports tubular receiving member 40. Trolley support member 110 is attached with carriage support member 70 and supports opposed trolley tracks 112 and tubular unloading arm 80. Tubular unloading arm 80 is shown in its retracted or loading position in

A tubular 100 on tubular receiving member 40 has already rolled from the carriage 30 middle level or tier support member 23 through an opening in cartridge 20 for that tier. As can now be understood, cartridge 30 may support multiple levels or tiers of tubulars that are separated by different support members such as members (21, 23, 25). Comparing

Tubular indexing system, generally designated 140, with first tubular indexing member 160 and second tubular indexing member 170 is pivotally positioned from tubular receiving member 40 using pivot member 154. Tubular indexing system 140 is shown in the loading position for loading tubulars from cartridge 172 to tubular receiving member 40. The preferred angle from horizontal of the tubular indexing system 140 loading position is approximately 10 degrees. However, other angles are contemplated to achieve rolling of the tubulars using only gravity. It is contemplated that the angle of tubular indexing system 140 in the loading position may be substantially the same angle from horizontal as cartridge 172 in the first tubular tier position. Tubular indexing system hydraulic cylinder 315 may be used to move tubular indexing support member 156. Other methods of moving tubular indexing support member 156 are contemplated. Tubular indexing system hydraulic cylinder 315 may be operated remotely. Tubulars roll across inclined top surface 157 of tubular indexing support member 156 when traveling between cartridge 172 and tubular receiving member 40, such as tubular 180 has already done. Tubular indexing members (160, 170) are shown in their extended or blocking positions.
First tubular indexing member 160 and second tubular indexing member 170 may be hydraulically operated from a remote location, such as the control panel discussed above. Other numbers of tubular indexing or blocking members (160, 170) are contemplated. It is contemplated that tubular indexing system 140 may be mechanical, hydraulic, electrical, electro-magnetic, or other type. It is further contemplated that the three tubular indexing systems 140 may be remotely operated in synchronized fashion. Sensors may be used to determine the positions of indexing members (160, 170). Tubular indexing system 140 may also be adjusted for various sizes of tubulars. Tubular indexing members (160, 170) may be independently extended or retracted, as shown in
Tubular 180 has already rolled from the cartridge 172 when first indexing member 160 then the second member 170 were retracted. It is contemplated that when the retainer pin 150C for cartridge lower support member 174 is first retracted after the carriage is in the first tubular tier position, both first tubular indexing member 160 and second tubular indexing member 170 would be in the extended position as shown in
In
It is also contemplated that other combinations of positions of members (160, 170) may be used, such as second tubular indexing member 170 being in the blocking position to block tubular 320 as it moves from tubular receiving member 40, and first tubular indexing member 160 being in the unblocking position. After the tubular 320 has come to rest against second tubular indexing member 170, second tubular indexing member 170 may be moved to the unblocking position to allow tubular 320 to roll past the unblocked first tubular indexing member 160 onto cartridge lower tier support member 174 of cartridge 172. It is also contemplated that both indexing members (160, 170) may remain in the unblocking position during unloading so that a tubular such as tubular 320 may not be blocked by either indexing member (160, 170) as it moves from tubular receiving member 40 to cartridge 172.

Method of Use
As used hereafter, unless otherwise stated, loading refers to loading tubulars from a cartridge to a tubular receiving member 40. Unloading refers to unloading tubulars from a tubular receiving member 40 to a cartridge. For loading operations, a cartridge containing tubulars may be positioned between two carriages. In the preferred embodiment, the cartridge is positioned on two carriages (30A, 30B) as shown in
Before the retainer pin 150C for cartridge lower support member 174 is retracted and before the carriage is tilted to the first tubular tier position, tubular indexing system 140 is moved in the loading position as shown in
A tubular loaded from the cartridge on the tubular receiving member may then be pushed by trolley (60, 60A, 60B) using trolley shoulder member (205, 226) along tubular retainer member 40 toward the drilling deck. The tubular raiser 130, shown
The carriage may then be moved into the second tubular tier position, as shown in
For unloading operations, one end of a tubular used on the derrick S may be placed by rig equipment on the tubular receiving member 40. As shown in
Unloading arm(s) 80 are used to unload the tubular from the tubular receiving member 40 to the tubular indexing system(s) 140. After a tubular has come to rest against the first tubular indexing member 160, the first tubular indexing member 160 may be retracted to allow the tubular to roll from the force of gravity onto the cartridge. In
The foregoing disclosure and description of the invention are illustrative and explanatory thereof, and various changes in the details of the illustrated apparatus and system, and the construction and method of operation may be made without departing from the spirit of the invention.
