Description
- The present application claims priority to
U.S. Patent Application Serial No. 13/898,260, filed May 20, 2013 13/459,314, filed April 30, 2012 U.S. Provisional Patent Application Serial No. 61/481,216, filed May 1, 2011 - In oilfield applications, for example, in deep-sea locations, heavy tubulars extend downward from the platform and may be supported by engagement with a landing string. Depending on the particular application (i.e., drilling, completion, etc.), the landing string may be provided by drill pipe or other high-tensile tubulars. Such landing strings are often required to support a heavy load, such that traditional running systems, which generally employ slips or bushings to hold the tubular by engaging the outer diameter thereof, are inadequate. Further, as offshore drilling operations continually push into deeper water, the tensile load transmission from the landing string to the rig continues to increase in order to support the increased string weight, which is increasingly causing "slip crushing," whereby the slips and/or bushings engage the tubular body with such force that the tubular body is crushed or otherwise damaged.
- To avoid this, landing strings are typically lowered by engagement with an upset (i.e., a shoulder) on the tubular body of the landing string. One way to do this is to employ dual-upset tubulars, allowing the tubular to be lowered by engaging one upset with the elevator and the second with the spider. Another common method shuttles or circulates a pair of elevators to ensure that only the upset is engaged, thereby obviating the need for special dual-upset tubulars. The first elevator begins suspended by the bails, while the second elevator acts as a spider, resting on the rotary table and supporting the landing string by the upset of the uppermost tubular of the landing string (i.e., the most recently run-in segment). The first elevator engages a the exposed box of the landing string. The slips or bushings of the second elevator are then disengaged from the upset and the second elevator is removed; thus, the weight of the landing string is transmitted through the new tubular segment to the first elevator. The first elevator then lowers until it abuts the rotary table, and, as such, now acts as a spider. The bails are then switched to the second elevator, which engages another new tubular segment, and the process is repeated.
- Such known processes have significant drawbacks, requiring special dual-upset tubulars or time-consuming switching of bails between elevators. What is needed are faster, more cost-effective methods and apparatus for lowering such heavy tubulars, while avoiding slip crushing.

Figure 1 illustrates a perspective view of anexemplary running system 10, according to an embodiment described. Theexemplary running system 10 may be particularly useful for running landing strings; however, it will be appreciated that the runningsystem 10 disclosed herein may be equally applicable to running, lowering, raising, making-up, breaking-out, or otherwise moving any type of tubulars for any purpose. The runningsystem 10 generally includes first and secondtubular engagement devices tubular engagement device 12 is movable, and may be referred to as anelevator 12. The secondtubular engagement device 14, on the other hand, may be stationary and may be referred to as aspider 14. - As shown, the
elevator 12 includes abody 16, which may have a generally cylindrical shape and opposingflats Ears flats elevator 12 may be suspended from the rig (e.g., via a traveling block and/or top drive, not shown) and movable vertically toward or away from thespider 14. Thebody 16 defines acentral bore 26 therethrough, in which grippingassemblies Channels bore 26, between adjacentgripping assemblies - As indicated for the gripping
assembly 28, each of thegripping assemblies housing 44, abracket 46, apiston 48, and awedge 50. As the term is used herein, "wedge" is intended to be broadly defined to include slips, bushings, bushing segments, or any like structures capable of applying a gripping force to a tubular, whether including teeth or not. In the illustrated embodiment, thewedge 50 is free from teeth or other marking structures. The taperedhousing 44 is generally positioned in thebore 26 and bears on thebody 16; further, the taperedhousing 44 may be integral with a remainder of thebody 16 and/or may be coupled thereto. The taperedhousing 44 is tapered such that it extends radially inward, proceeding downwards, and provides achannel 45 in which thebracket 46 andpiston 48 are at least partially disposed. Thebracket 46 is moved in thechannel 45 by movement of thepiston 48. In various embodiments, thepiston 48 may be moved or articulated by a hydraulic assembly, as is well-known in the art. In other embodiments, thepiston 48 may be driven by pneumatics, motors, springs, linkages, combinations thereof, or the like. Further, thebracket 46 may be configured to transmit longitudinal, for example, upward, force on thewedge 50, to disengage thewedge 50 from a tubular (not shown), as will be described in greater detail below. Although fourgripping assemblies - Turning to the
spider 14, thespider 14 includes abody 100, which may be generally cylindrical in shape and may have an increased-radius shoulder 101 defining at least a portion of the top of thebody 100. Theshoulder 101 of thebody 100 defines flats (three are visible: 102, 104, 106) on its outer diameter for engagement with various tools or other structures, as will be described in greater detail below. Further, theshoulder 101 may define alanding surface 108 on the upper side thereof. Thebody 100 may also define abore 103 extending axially therethrough, for receiving a tubular (not shown). Proximal the top of thebore 103, thebody 100 may define anannular seat 105, which is recessed from thelanding surface 108. - In at least one embodiment, the
body 100 may be split, as shown, defining two or more generally arc-shapedsegments segments 109a,b may be held together by an interior surface defined in the rotary table (not shown), as is known in the art. In other embodiments, however, other structures such as a retaining collar or the like may be used to secure the position of thebody 100. Additionally, in still other embodiments, thesegments 109a,b may be coupled together via a hinge (not shown) or any other coupling mechanism. - Gripping assemblies (e.g., bushing or slip assemblies) 110, 112, 114, 116 may extend upward from the
landing surface 108 and theseat 105 and inward from thebore 103.Channels gripping assemblies gripping assembly 110, each grippingassembly tapered housing 126, abracket 128, awedge 130, and apiston 132. Further, thehousing 126 provides achannel 135 therein for guiding longitudinal movement of thebracket 128. Thebracket 128 is coupled to thewedge 130 and may be configured to transfer longitudinal force from thepiston 132 to thewedge 130, for example, to raise or lower thewedge 130 into or out of engagement with a tubular (not shown). Thepiston 132 may be driven to move thebracket 128 by pneumatics, hydraulics, motors, mechanical linkages, springs, combinations thereof, or the like. -
Figures 2-7 illustrate an exemplary operation of the runningsystem 10, whereby a sequence of theelevator 12 engaging and moving a tubular 200, lowering the tubular 200 through thespider 14, transferring load to thespider 14, and disengaging from the tubular 200 is illustrated. It will be appreciated that this sequence may be reversed, or otherwise rearranged without departing from the scope of this disclosure. - Referring now specifically to
Figure 2 , there is illustrated a perspective view and a top view, respectively, of theelevator 12, according to an embodiment described. As shown, the grippingassemblies Figure 2 ) thereof, are configured to releasably engage the tubular 200. Thewedges 50 may be drawn downward by engagement with the tubular 200 or by driving thepiston 48 downward, as described above. The taperedhousing 44 is generally prevented from moving radially outward by thebody 16, and thus thewedges 50 sliding downward causes thewedges 50 to move inward, toward the tubular 200, until thewedges 50 securely engage the tubular 200. The bails (not shown) coupled to theears elevator 12 in thechannels -
Figure 3 illustrates a perspective view of the runningsystem 10, with theelevator 12 and thespider 14 being moved vertically into close proximity with one another, according to an embodiment described. As theelevator 12 is lowered, the grippingassemblies elevator 12 may be angularly aligned with thechannels channels Figure 4 ) of thespider 14, while thegripping assemblies body 16 of theelevator 12 to the rig (not shown). During this time, thespider 14 generally does not engage the tubular 200 to bear its weight, although in some instances, it is contemplated that thespider 14 may provide guidance for the lowering of the tubular 200. In at least one specific embodiment, theelevator 12 is lowered toward thespider 14 while engaging an upset (not shown) of the tubular 200, as will be described in greater detail below. - As also illustrated in
Figure 3 , thebody 100 of thespider 14 is surrounded by the rotary table 134. In one embodiment, the rotary table 134 defines a generally rectangularinner surface 136, with the generallycylindrical body 100 being inscribed therein. Theflats flats Figure 3 ) of the shoulder 1 01 of thebody 100 may bear on theinner surface 136. Accordingly, thesegments 109a,b of thebody 100 may be restrained from separating by the rotary table 134, thereby preventing thegripping assemblies spider 14 from moving radially-outward. As discussed above, however, it will be appreciated that thebody 100 of thespider 14 may, in some embodiments, not be segmented, may be hinged, and/or may include more than two segments. - With continuing reference to
Figures 3-5 illustrate perspective and top views, respectively, of the runningsystem 10, showing theelevator 12 transferring the load of the tubular 200 to thespider 14, according to an embodiment described. Thegripping assemblies elevator 12 and are sized to slide axially and fit at least partially in thechannels elevator 12. Correspondingly, the grippingassemblies elevator 12 are positioned and sized so as to align with and slide at least partially in thechannels Figure 1 ). As shown inFigures 4 and5 , theelevator 12 is thus received into thespider 14, such that, in an exemplary embodiment, theelevator 12 rests on the landing surface 108 (Figure 3 ) of thespider 14. The enmeshedgripping assemblies elevator 12 and thespider 14, respectively, are thus both positioned about the tubular 200 at approximately equal axial locations. - Accordingly, the gripping
assemblies spider 14 may be engaged when theelevator 12 comes into proximity with, for example lands on, the landing surface 108 (Figure 3 ). As such, the grippingassemblies spider 14 are at approximately the same axial location on the tubular 200 as are thegripping assemblies elevator 12. Thegripping assemblies gripping assemblies elevator 12 are also engaged, though at different circumferential locations about the tubular 200. Once the engagement between thespider 14 and the tubular 200 is secured, the grippingassemblies elevator 12 may be disengaged. As such, theelevator 12 releases the tubular 200, and the weight of the tubular 200 is transferred seamlessly to thespider 14. To remove theelevator 12 from the tubular 200, theelevator 12 may be raised upwards, may have a hinge (not shown) that can open to allow theelevator 12 to be laterally removed, or may be otherwise configured for removal. As will be appreciated, this enmeshing of thegripping assemblies spider 14 and theelevator 12 to engage a single upset, transfer the load between the two (e.g., from theelevator 12 to the spider 14), and release theelevator 12 so that it may be used to engage another tubular (not shown), to repeat the engaging and lowering process. -
Figures 6 and7 illustrate perspective and top views, respectively, of thespider 14 engaging the tubular 200, according to an embodiment described. After the upset of the tubular 200 has been lowered onto thespider 14, and the weight of the tubular 200 has been transferred to thespider 14, the elevator 12 (e.g.,Figure 5 ) may be removed. As such, the grippingassemblies spider 14 engage and maintain the position of the tubular 200, while the rotary table 134 maintains the radial position of thebody 100, and thus of thegripping assemblies - Referring to
Figures 1-7 , although thegripping assemblies spider 14 are illustrated as extending upward for being received into thechannels elevator 12, while thegripping assemblies bore 26 of theelevator 12, it will be appreciated that variations of this arrangement are within the scope of this disclosure. For example, the grippingassemblies channels spider 14. In such embodiments, the grippingassemblies landing surface 108, may reside partially within thebore 103 and partially extending upward from thelanding surface 108, or may extend at least partially, or even entirely, down from thelanding surface 108, or from a point in thebore 103 below thelanding surface 108. - Moreover, it will be appreciated that either or both of the
tubular engagement devices tubular engagement device 12 may be stationary, while the secondtubular engagement device 14 is movable. Additionally, the illustrated views of runningsystem 10 may be flipped, such that the firsttubular engagement device 12 is moved upward to the secondtubular engagement device 14, or the secondtubular engagement device 14 is lowered to the firsttubular engagement device 12. - Turning now to
Figure 8 , there is illustrated a simplified, side, cross-sectional view of a portion of the tubular 200 being engaged by atubular engagement device 300, according to an embodiment described. Thetubular engagement device 300 may be generally representative of the structure and operation of theelevator 12 and/or thespider 14 described above. Accordingly, thetubular engagement device 300 generally includesgripping assemblies gripping assemblies gripping assemblies tapered housing wedge 308, 310, respectively. Thewedges 308, 310 are slidable with respect to thehousings wedges 308, 310 are drawn downward, for example, by friction from engagement with the tubular 200 and/or by pneumatics, hydraulics, motors, linkages, or the like, thewedges 308, 310 are pushed inwards into engagement with the tubular 200. The taperedhousing wedges 308, 310. As such, the base 312 transfers the weight of the tubular 200, either by resting on a platform (e.g., for a spider), by hanging from the rig via bails (e.g., for an elevator), or in any other suitable manner. - The
wedges 308, 310 each define upper and lowerinterior surfaces interior surfaces central axis 322, proceeding downwardly. The lowerinterior surfaces axis 322. In other embodiments, however, the lowerinterior surfaces central axis 322, proceeding downward. In some embodiments, one, some, or all of the upper and/or lowerinterior surfaces surfaces - The upper
interior surfaces tubular body 326, as shown, but in other embodiments may extend radially inward. In various embodiments, the upset 324 may be disposed on (e.g., fastened, welded, brazed, or otherwise connected to, integral with, or otherwise part of) the tubular 200. The upset 324 may be capable of withstanding greater tensile forces than thetubular body 326 and transmitting such axial forces to thegripping assemblies gripping assemblies - To provide further load distribution, the lower
interior surfaces tubular body 326, as shown. Accordingly, some of the axial load of the tubular 200 weight is transmitted via the radial gripping force applied by the grippingassemblies tubular body 326. By simultaneously engaging the upset 324 with the upperinterior surfaces tubular body 326 with the lowerinterior surfaces assemblies tubular engagement device 300, and ultimately the rig may be able to support and run the tubular 200, while supporting strings having a greater weight than that which a simple engagement with the upset 324, let alone engagement only with thetubular body 326 by itself, is capable of safely handling. -
Figure 9 illustrates amethod 400 for lowering a tubular, according to an embodiment described. Themethod 400 may proceed by operation of the runningsystem 10 and/or thetubular engagement device 300 described above with reference toFigures 1-9 and may be best understood with reference thereto. Themethod 400 includes engaging an upset of the tubular with gripping assemblies of a first tubular engagement device, as at 402. More particularly, in at least one embodiment, such engagement may include simultaneously engaging the upset and a body of the tubular to support a weight of the tubular via engagement with both the upset and the body. The tubular supported by the first tubular engagement device, as at 402, may then be lowered into and made-up to a tubular string, such that themethod 400 includes supporting the weight of the string of tubulars with the first engagement device. - The
method 400 further includes vertically moving, for example, lowering the tubular through a second tubular engagement device by lowering the first tubular engagement device, as at 404. Themethod 400 may also include receiving gripping assemblies of the second tubular engagement device into channels defined between gripping assemblies of the first tubular engagement device, as at 406. Themethod 400 may also include engaging the upset of the tubular with the gripping assemblies of the second tubular engagement device, as at 408. Themethod 400 may further include disengaging the upset of the tubular from the gripping assemblies of the first tubular engagement device, such that the upset is supported by the second tubular engagement device, as at 410. - Referring now to
Figures 10 and 11 , a first engagement device, orelevator 512, in accordance with one or more embodiments of the present disclosure is shown in top (Figure 10 ) and perspective (Figure 11 ) views. Similar toelevators 12 depicted inFigures 1-5 ,elevator 512 ofFigures 10 and 11 includes amain body 516, a pair offlats ears gripping assemblies 528, and a plurality of channels (not visible) configured to receive plurality of gripping assemblies (e.g., 550 ofFigures 12 and 13 ) of a corresponding spider (e.g., 514 ofFigures 12 and 13 ). - Referring now to

Thus, aselevator 512 supporting a tubular member withgripping assemblies 528 is lowered tospider 514, the protruding grippingassemblies 528 may be received intochannels 552 ofspider 514 so that collision and/or interference betweengripping assemblies elevator 512 axially approachesspider 514, as described above in reference toFigures 1-9 . - Referring now to
Figures 10-13 together,elevator 512 andspider 514 further comprise one or more alignment features to ensure thatgripping assemblies 528 ofelevator 512 properly engagechannels 552 ofspider 514, andgripping assemblies 550 ofspider 514 properly engage channels (not visible) withinelevator 512. As used herein, the phrase "proper engagement" refers to an axial engagement ofelevator 512 withspider 514 such that gripping assemblies (528 and 550, respectively) are allowed to engage with their corresponding channels without engaging, interfering, or otherwise impacting each other aselevator 512 is lowered proximate to and on top ofspider 514. - As can be best viewed in top view
Figures 10 and12 ,elevator 512 is shown comprising two alignment features in the form of bore holes 560 and 562, whilespider 514 is shown comprising two alignment features in the form of bore holes 564 and 566. Alignment feature bore holes 560, 562, 564, and 566 may be used in combination with alignment rods (not shown) to ensure that aselevator 512 is lowered tospider 514 by a rig's draw works, proper radial alignment ofgripping assemblies holes spider 514 to allow slidable engagement withholes elevator 512, and in other embodiments, alignment rods may be rigidly affixed withinholes elevator 512 to allow slidable engagement withholes spider 514. - Additionally, in selected embodiments, alignment rods may be tapered at a free end to facilitate engagement within alignment features (i.e., holes) 560 and 562, or 564 and 566, and in other embodiments alignment feature bore holes may be tapered to facilitate engagement with free ends of alignment rods. Additionally, alignment rods used in conjunction with alignment features 560, 562, 564, and 566 may extend the entire length of the draw works to maintain radial alignment of
elevator 512 withspider 514 along the entire lifting stroke ofelevator 512 or, in alternative embodiments, alignment rods may only be of sufficient length to maintain radial alignment ofelevator 512 withspider 514 for a portion of the lifting stroke ofelevator 512. - Referring now to
