Definitions
- Each of the pipe transfer devices consists of a frame structure including a horizontally extended arm on which a carriage is shiftable, the carriage carrying vertically shiftable pipe stand engaging heads, and the carriages of all of the pipetransfer devices being driven by a common drive.
- the pipe handling apparatus includes a combined catcher and positioner for the lower end of the pipe stand as it approaches a vertical position in the derrick whereby to confine the lower end of the stand against undesired movement and to position the stand above the drill string supported in the rotary table; the catcher and positioning devicealso being operable to engage and move the lower end of the drill collar between a position above the rotary table and a vertically racked position.
- the apparatus also includes an upper racker device for engaging and moving the upper end of the drill collars between a position above the rotary table and an offset vertically racked position.
- the present invention providesnovel pipe transfer apparatus for use in moving stands of drill pipe, either doubles or trebles between horizontally racked positions and a position aligned with the center line of the derrick, wherein the pipe transfer apparatus comprises ,a plurality of similar support and arm structures, each arm having a carriage shiftable thereon and each carriage having a vertically shiftable pipe engaging head for picking up the pipe at either position and supporting the pipe as it is moved between such positions.
- Associated with each pipe transfer structure are laterally spaced posts between which the pipe stands are confined in vertical rows.
- the plurality of pipe transfer devices are all spaced relative to one another so that three such transfer devices are adapted to engage and support a treble drill pipe stand at such locations that the sag of the pipe stand between points of support is minimized, and therefore the pipe will not be overly stressed.
- the posts are associated with the pipe transfer devices, it is not possible for the pipe transfer heads to place the engaged portions of the pipe stand between one pair of I posts while an intermediate portion of the pipe is placed between another pair of laterally spaced posts, notwithstanding the existence of some sag in the unsupported section of pipe stand, and notwithstanding the tendency of the sagging portion of the stand to swing relative to the fixed rack, for example, in response to vigorous rolling of a floating vessel.
- the present invention provides means located above the derrick floor to engage and confine the lower end of a stand of drill pipe against undesired swinging movement as it is being moved between a position aligned with the center line of the derrick and a position on the dolly. More particularly, such means provides a throat into which the lower end of the pipe stand moves as the dolly approaches the center line of the derrick during the addition of a pipe stand to the drill string, and a latch is closed about the drill string to confine it in the throat against swinging movements.
- the lower end of the stand while confined against undesired lateral movement in any direction, is positively positioned substantially in alignment with the drill string supported in the rotary table, and the stand is slidable in the throat to allow the stand to be stabbed into the upper end of the drill string.
- the pipe engaging and positioning means is shiftable to an out-of-the-way position and thence to a standby position for receiving the next stand.
- the pipe engaging and positioning means may be engaged with the lower end of the stand of drill pipe supported by the usual elevator, as the stand is broken out of the drill string, and while the stand is confined against undesired lateral swinging movement, the lower end of the stand is positively positioned Since, as previously indicated, undesired swinging of the drill collars also poses a problem, the present invention also contemplates the provision of pipe engaging and positioning means which is also engageable with the lower end of a drill collar as the latter is positively moved between a position aligned with the center line of the derrick and a vertically racked position.
- the invention contemplates in one form, the provision of a pipe engaging and positioning head having a common throat and a latch for holding therein either a drill pipe stand or drill collar; and in another embodiment of the invention, the pipe gripping means comprises a compound head adapted at one side to engage and confine a drill pipe stand, and adapted at the other side to engage and confine a drill collar, the head being mounted for movement to the necessary location for receiving and confining and for releasing both the drill pipe stand and the drill collar.
- the invention also contemplates the provision of a dolly which is so constructed as to interfit with the tool joint of the pipe stand, so that motion of the dolly is positively transmitted to the pipe stand to cause it to accelerate and move with the dolly at the desired rate and in the desired direction, notwithstanding inertia tending to preclude such acceleration and movement and notwithstanding other forces resulting from the movement of a vessel on which the rack and pipe handling apparatus will be employed.

- the track 10 comprises a pair of laterally spaced rails 11 between which is supported a dolly, generally denoted at 12, the dolly being as will hereinafter be described movable between a stop 13 at a location spaced from the rotary table R and an outer tail stop 14 at the outer end of the track 10.
- V rollers 15, 16 and 17 Spaced along the path of the track 10 and disposed between the rails 11 are suitable V rollers 15, 16 and 17 suitably mounted on the deck S of a ship or on the derrick substructure D and being revolvably mounted at the upper ends of the respective ends of actuator rods 15a, 16a and 17a of vertically disposed actuator cylinders 15b, 16b and 17b.
- Stands of drill pipe DP are adapted to be moved between the racked positions in the racks PR, and the position shown in broken lines in FIG. 1 with one end of a pipe stand DP engageable with or releasable from the elevator E and with the other end of the stand resting in the dolly 12.
- the dolly 12 comprises a body 3 having rollers 4 at its opposite sides engaged in the opposing rails, as well as side rollers 5 which engage the sides of the rails 11.
- an upstanding end wall 6 adapted to engage the end of a stand of pipe DP disposed in the dolly.
- a pair of upwardly divergent side walls 7 providing a seat for the tool joint for the stand of drill pipe.
- another pair of upwardly divergent side walls 8 at the apex of which is an arched key seat 9 of a size smaller than the tool joint but adapted to receive the body of the drill pipe.
- the end of the pipe stand when the end of the pipe stand is placed in the dolly, it is positively engageable with the end wall 6 of the dolly and in the key seat 9, so that the dolly may be powered toward the derrick to position the pipe stand DP for engagement by the elevator E.
- the tool joint when a stand of drill pipe DP is lowered onto the dolly from the derrick and is to be returned to the rack, the tool joint will be positively engaged to assure that the pipe stand can be accelerated and moved to the racking position.
- a cable drive as seen in FIG. 2, comprising a drive motor for effecting rotation of a drum 21, as seen in FIG. 1, in opposite directions.
- the cable 22 has a portion frictionally engaged with the drum 21 and extends about a sheave 23 at the inner end of the track and about another sheave 24 at the other end of the track, and the cable is connected to the dolly so as to effect powered movement of the dolly in either direction longitudinally of the track 10.
- the respective pipe transfer devices U previously referred to are typified by a transfer device as illustrated in FIG. 4. These transfer devices are adapted to be made up in units.
- Each unit comprises a lower supporting beam 25 adapted to be mounted'upon a substructure 26.
- the beam is provided with a flange 27 for connecting it as by fasteners 27a in endwise relation to the corresponding beam of the opposing unit.
- Adjacent its outer end, the beam supports a vertical post 28.
- another vertical post 29 is provided at the outer extremity of the beam.
- the posts 28, 29 extend above the arm 30 to facilitate the connection of suitable struts 31, 32 to the posts and to the arm to fortify the connection of the arm to the posts.
- the arm 30 On its upper and lower faces, the arm 30 has welded thereon inverted angle irons providing longitudinally extended tracks 33, 34 (See FIG. 5).
- Shiftable on the arm is a carriage 36 which is provided with a plurality of rollers 37 engaged with the upper track and an opposing plurality of rollers 38 engageable with the lower track, whereby rocking of the carriage on the arm is precluded, but the carriage is freely shiftable longitudinally on the arm.
- a pipe transfer device Mounted in spaced relation to the carriage 36 by suitable connecting members 39 is a pipe transfer device generally indicated at 40 and including an actuator 41 and a head 42.
- the actuator structure 41 comprises an outer rectangular hollow body 43 in which is reciprocably disposed an inner rectangular body 44. lntemally of the inner body 44 is the cylinder 45 of a fluid pressure actuator. The upper end 46 of the cylinder is suitably connected to the upper end 47 of the outer body 43. Extending from the lower end of the cylinder 45 is the actuator rod 48 which is pinned, as at 49, or otherwise suitably connected at the lower end of the inner body 44, whereby extension of the rod from the cylinder will effect downward movement of the inner body and retraction of the rod will effect upward movement of the inner body.
- Fluid under pressure is adapted to be supplied to the opposite ends of the cylinder through conduits 50 and 51 which extend into the inner body and are connected to the ends of the cylinder, the conduit 50 extending downwardly in the space between the cylinder 45 and the inner body 44 for connection to the lower end of the cylinder.
- the pipe transfer head is suitably affixed to the lower extremity of the inner body 44 as by fasteners 52 and includes a downwardly opening and upwardly flared throat 53.
- the head has a latch 54 pivotally connected thereto by a pivot pin 55 and adapted in one position to engage and retain the pipe stand DP in the throat 53 of the head and adapted in the other position to allow the head to move downwardly onto the pipe stand and to allow a pipe supported in the head to be released.
- the latch 54 has an arm 56 which will partially block the throat 53 when the latch is open, so that when the latch is closed by an actuator cylinder 540, the opening for the pipe is larger than the pipe.
- a part of the unit is a plurality of laterally spaced pipe retainer posts 60, each fixed to and projecting upwardly from the beam in parallel spaced relation for receiving therebetween vertical rows of pipe stands DP.
- drive means are provided comprising a chain 61 extending about a pair of sprockets 62, 63 mounted at the opposite ends of the arm 30 and connected to opposite ends of the carriage.
- one of the sprockets 63 is driven by a power source or motor 64, say through a reduction gear box 65, and the other sprockets 63 of the other units U are connected to jackshafts 66 which extend from the power source to the other two units U.
- the position of the head 42 of all of the units U may be controlled from a remote location or may be automatically controlled by suitable position sensing control devices, not shown, which can control the drive motor 64 either in response to the longitudinal position of the carriages 36 on the arms 30 or in response to the angular position of the jackshafts 66, but in any event, all of the carriages on all arms 30 of each of the unit U at either side of the racking assembly will be driven in unison and will correspondingly position the respective heads 42.
- the units U are pre-fabricated and are adapted to be interconnected with other similar units so as to provide right hand and left hand pipe racks disposed at opposite sides of track 10.
- means are provided for supporting the rails 11 of the track 10 between the opposing units U, which can be readilly assembled in the field.
- the tracks 10 are suitably supported on horizontal support members 70 having mounting flanges 71 adapted to be suitably connected to the innermost posts 60 of a pair of pipe rack units U.
- the rails 11 may be transported to the installation site in comparatively short lengths and assembled with the rack units U so as to extend radially of the center line of the derrick D.
- the cable 22 may be extended about the sheaves 23 and 24 and the cable drum 21 and connected to the opposite ends of the dolly 12.
- the pipe transfer or racking units U may be conveniently arranged or spaced so as to support a treble stand of drill pipe at locations spaced inwardly from the extremities of the stand and at an intermediate location notwithstanding approximately at the middle of the intermediate joint of pipe in the stand.
- the pipe transfer or racking units U are preferably so spaced that an adjacent pair of units U, the outermost pair in the illustrative arrangement, are adapted to handle a double length stand of drill pipe, the spacing of the transfer or racking units being such that both treble and double stands are supported at spaced locations whereby to limit the sagging of the intermediate unsupported portion of the stand beyond the elastic limit of the pipe.
- the pipe racking posts 60 are located substantially beneath the pipe engaging heads 42 of the respective units U, the pipe stands can only be placed between posts which are aligned in the respective units, notwithstanding that substantial sag may exist between the supported points in the pipe stand and that such sagging portions may tend to swing responsive to the roll of the vessel.
- the apparatus is operable to move pipe stands DP between racked positions, between the posts 60, and a position at which one end of the stand is supported on the rollers and 16 located between rails 11 of the track 10.
- the apparatus is operable to move the dolly 12, elevate the rollers 16 and 17, and lower such rollers, so that a pipe stand DP is shiftable between the aforementioned position supported on the dolly and rollers 15 and 16 and the position shown in broken lines in FIG. 1, at which one end of the pipe stand DP extends into the derrick so as to be either engaged by or released from the elevator E.
- the elevator E When a pipe stand DP is being added to the drill string DS, the elevator E will be either manually or automatically closed about the portion of the pipe stand disposed between the elevator links L. As the traveling block T is elevated, the dolly 12 will be moved further inwardly and the rollers 16 and 17 retracted to allow the dolly to move into engagement with the inner stop 13, at which time the upper end of the pipe stand is substantially at the center line of the derrick, but the lower end of the pipe stand is located on the dolly 12 to one side of the center line of the derrick, as seen in FIG. 10.
- the pipe stand DP when the pipe stand DP is being removed from the drill string DS, the pipe stand will initially be suspended in the derrick by the elevator E, and the lower end of the suspended pipe stand DP must be swung off to the side so as to be placed into the dolly 12, and thereafter, the dolly may be actuated to move outwardly on the track 10 as the upper end of the pipe stand DP is lowered by the suspension apparatus including the traveling block T, until the pipe stand assumes the broken line position of FIG. 1.
- means are provided to confine the lower end of the pipe stand as it is moved between the center line of the derrick and the dolly 12 so as to prevent undesired motion of the lower end of the pipe stand and so as to eliminate the need for manually handling of the lower end of the pipe stand, such means also being operable to position the lower end of the suspended pipe stand DP either on the dolly 12 or at the center line of the derrick.
- Such confining and positioning means for the lower end of the pipe stand DP is generally indicated at 80 in the embodiment shown in FIGS. 1 through 13.
- the means 80 for confining the lower end of the pipe stand DP against undesired movement and for positioning the lower end of the pipe stand comprises, as best seen in FIGS. 10 through 12, an arm 81 pivotally supported by a vertical pin 82 on a flange 83 which projects outwardly from a carriage 84, the carriage 84 being shiftably supported for horizontal movement from side to side of the derrick at a connecting side of the derrick by a track 85 comprising a pair of rails 86.

- suitable drive means are provided including in the illustrative embodiment, a reversible motor 90 mounted beneath the carriage 84 and adapted to drive a sprocket 91 engaged with a chain 92 which extends longitudinally between the rails 86 and which is anchored at its opposite ends on the stops 88 and 89.
- the arm 81 has a generally V-shaped throat 92 opening laterally so as to receive the lower end of a drill pipe stand DP.
- a gate 93 is pivotally mounted on the arm 81, as at 94.
- the gate 93 is connected to the rod 95 of a double acting actuator cylinder 96 which is pivotally connected, as at 97, to the arm 81 and to which pressure fluid can be supplied from an appropriate source (not shown).
- the gate 93 is closed by the actuator cylinder 96 and its rod to confine the lower end of the pipe stand DP against lateral displacement from the throat 92.
- the positioning carriage 84 may then be actuated by the motor 90 to drive the carriage to the broken line position of FIG. 10 at which the lower end of the pipe stand DP is positioned at the center line of the derrick.
- the arm 81 is adapted to be disposed in the broken line position of FIG. 10, at which position the gate 93 may be closed to confine the pipe stand in the throat 92 so that the carriage 84 may then be actuated to the full line position of FIG. 10, at which position the lower end of the pipe stand DP may be lowered into the dolly 12 before the gate 93 is opened.
- actuator means including a rod 99, connected as at 100, to the am 81, and reciprocable in a double acting actuator cylinder 101, pivotally connected, as at 102, to the carriage 84, are provided for effecting retraction of the arm 81, in response to the application of pressure fluid to the cylinder 101 to either retract or extend the rod 99.
- the ability of the positioning arm 81 to be retracted enables the confining and positioning means 80, just described above, to also be employed in the racking of drill collars vertically in the derrick.
- a number of drill collars DC are shown in FIG. 1 as being racked in an upper finger board 105, the lower ends of the drill collars DC being disposed in a receptacle 106 on the floor of the derrick.
- the drill collars are moved at their lower ends between racked positions and a position at the center line of the derrick by the confining and positioning means 80, and the upper ends of the drill collars are moved by a similar structure 180, shown more particularly in FIG. 3, and located aloft in the derrick above the finger board 105.
- the finger board is shown in general to include a frame 110 suitably affixed to the derrick structure and providing a plurality of parallel,- spaced arms 111, 112 and 113 defining elongated openings adapted to receive the upper ends of the lengths of drill collars DC.
- a frame 110 suitably affixed to the derrick structure and providing a plurality of parallel,- spaced arms 111, 112 and 113 defining elongated openings adapted to receive the upper ends of the lengths of drill collars DC.
- the arm 112 in the illustrated structure has a number of retainer fingers 114 thereon, actuatable between closed positions defining compartments for the drill collars DC and open positions enabling drill collars to be moved into and from the spaces between the fingers 111, 112 and 113.
- the details of the finger actuators need not be elaborated upon herein, but they may be hydraulically opened and closed, as is well known.
- the means for controlling and positioning the upper ends of drill collars either in the finger board 105 or at the center line of the derrick comprises an arm 181 pivotally supported by a vertical pin 182 on a flange 183 which projects outwardly from a carriage 184 which, like the previously described carriage 84, is shiftably supported for movements from side to side of the derrick on a track 185 comprising a pair of rails 186.
- These rails 186 are suitably connected to the derrick structure, and the carriage 184 has rollers 187 engaged in the rails 186.
- Opposing shock absorbing stops 188 and 189 are provided to limit movement of the carriage, and a reversible motor 190 is mounted beneath the carriage 184 and adapted to drive a sprocket 191 which engages a chain 192 connected at its opposite ends to the stop 188 and 189.
- the arm 181 At its outer or free end, the arm 181 has a generally V- shaped throat 192 opening laterally so as to receive the upper end of a drill collar DC.
- a gate 193 is pivotally mounted on the arm 181, as at 194.
- the gate 193 is connected to the rod 195 of a double acting actuator cylinder 196 which is pivotally connected, as
- the drill collar confining and positioning means 180 When the drill collar confining and positioning means 180 is being employed to move the upper end of the drill collar to a racked position in the finger board 105 from the center line of the derrick or alternatively to move the upper end of the drill collar from the racked position to the center line of the derrick. It is necessary that the carriage 184 be shifted laterally in the derrick on the track 185 and in addition, that the arm 181 be pivoted between the extended position shown in FIG. 3 and a range of angular positions, whereby to place the drill collars DC in the spaces between the racking arms 111, 112 and 113 as well as to be retracted to a position substantially parallel with the track 185 so as to clear drill collars racked in the space between the rack arms 112 and 113.
- actuator means including a rod 199 connected, as at 200, to the arm 180 and reciprocable in a double acting actuator cylinder 201, pivotally connected, as at 202, to the carriage 184, are provided for effecting angular positioning or retraction of the arm 181, in response to the application of pressure fluid to the cylinder 201 to either retract or extend the rod 199.
- the racking of drill collars DC will now be described. Referring to FIG. 13, it will be noted that the lower ends of the drill collars DC are to be placed in the receptacle 106, or other conventional means for holding the lower ends of the drill collars in racked positions, by the positioning means 80 which is also employed to position the lower ends of the drill pipe stands DP.
- the positioning means 80 which is also employed to position the lower ends of the drill pipe stands DP.
- the lower end thereof With the drill collar so suspended, the lower end thereof is shifted laterally with respect to the center of the derrick by retracting the rod 99 into the cylinder 101 until the lower end of the drill collar is in alignment with the parallel spaces between the compartment walls 111a, 112a and 113a. Then, the carriage 84 may be shifted along the track 85 to dispose the lower end of the drill collar DC in the selected racked position. While the positioning means 80 holds the lower end of the drill collar DC, the upper positioning means 180 is operated to engage the upper end of the drill collar which is still located at approximately the center line of the derrick and which is still engaged in the elevator E which will be disengaged from the drill collar after the upper end of the drill collar is confined against lateral movement in the throat 192, as seen in FIG. 3.
- the positioning means 180 may be operated, for example, as required by the illustrative upper rack 105, to move the carriage 184 to the right, as seen in FIG. 3, to enable the arm 181 to be pivoted upon retraction of the actuator rod 199 to a position at which the upper end of the drill collar is aligned with one of the spaces between the rack arms 111, 112 and 113; whereupon the carriage may be actuated to the left, as seen in FIG. 3, to move the drill collar to a substantially vertical position, with its upper end in a location to be confined by closure of one of the rack fingers 114.
- the positioning means 180 is further retracted to clear racked drill collars and moved back to a position for engaging a subsequent drill collar.
- the lower positioning means 80 may either remain in engagement with the lower end of the drill collar undergoing positioning by the upper positioning means 180, or, if the lower receptacle 106 is capable of positively preventing movement of the lower end of the drill collar, the lower positioning means 80 may be returned to a standby position for engagement with the next drill collar in the drill string.
- the movement of drill collars from racked positions to the center line of the well for connection in the drill string essentially involves operations which are substantially the reverse of the operations employed to remove the drill collar drom the drill string and rack the same.
- the use of the present apparatus for racking pipe stands DP or unracking them and moving the stands between the derrick and the racked positions involves the following operations. If it is assumed that the drill string is being run into the well, either during the drilling operation or during round tripping of the drill string, a stand of drill pipe DP will be moved from the racked position between a pair of posts 60 of the respective rack units U at either the left or right hand side of track 10 which leads between the rack apparatus PR and the derrick floor F. To accomplish this, the motor 64 is operated to drive the jackshafts 66 so as to move all of the pipe transfer carriages 36 on one side to a position at which all of the heads 42 are above a selected space between the pipe rack posts 60.
- the actuators 40 for the heads are operated to lower the heads into positions at which closure of the latches 54 will enable the pipe stand to be lifted upon upward movement of the heads 42.
- carriages 36 are further actuated to move the heads 42 to positions above the track 10, at which positions the heads are lowered and the latches 54 opened so that the stand will be deposited on the supporting rollers 15 and 16 and on the dolly 12.
- the dolly is actuated and the rollers 16 and 17 progressively elevated until the pipe stand DP is in the position illustrated in FIG. 1, at which its upper end is engageable by the elevator E.
- the elevator E is latched about the pipe stand DP and the drawworks operated to lift the pipe stand into the derrick the dolly l2 traveling inwardly and supporting the lower end of the pipe stand until the dolly 12 is in the position shown in FIG. 10, in engagement with the inner stop 13.
- the confining and positioning means may have previously been moved to the standby position during elevation of the pipe stand DP, but in any event, is now positioned as shown in FIG. 10 to engage the pipe stand DP above the dolly 12, and when the gate 93 is closed, the pipe stand will be positively controlled against lateral movement, while being free for longitudinal movement. Thereupon, the positioning means 80 is shifted to the broken line position of FIG.
- the stand is suspended by the elevator E, and controlled to prevent undesired lateral movement by the positioning means 80 which engages the pipe stand before the stand is broken out of the drill string. Then, after breaking out the stand with the usual tongs, the lower end of the stand is moved positively to the position over the dolly 12.
- the pipe stand is lowered to engage the dolly, and the gate 93 opened to allow the pipe to move with the dolly as the stand is lowered by the hoisting mechanism, including the elevator E, to the broken line position of FIG. 1, where the elevator is released, freeing the pipe stand for movement with the dolly to the location between the rack units U for transfer to the racked position, as previously indicated.
- FIGS. 14 through 16 illustrate a modified positioning means which may be employed in lieu of either or both of the positioning means 80 and 180, and which is depicted in the position of the positioning means 80.
- the carriage 284 is supported by a track 285, the rails 286 of which are engaged by rollers 287 carried by the carriage. 284.
- the arm 281 in this embodiment, is reciprocable, as distinguished from the pivoted arms 81 and 181 previously described, and is preferably of rectangular form, slidably disposed in a complemental way 283 in the carriage, as seen in FIG. 15.
- the carriage is actuated along the rails 286 between shock absorbing stops 288 and 289 by a reversible motor 290 and a drive sprocket 291 which drivingly engages the chain 292 extending between the stops 288 and 289.
- the arm is reciprocated through the carriage by a reversible motor 300 which drives a sprocket 301, the sprocket engaging a chain 302 which is anchored adjacent to the ends of the arm 281, as also seen in FIG. 15.
- a head 304 adapted to confine and position drill pipe stands and adapted to confine and position drill collars.
- the drill pipe stand DP engages in a throat 292 and is confined by a gate 293 which is pivotally mounted at 294 and actuatable between open and closed positions by a double acting actuator 296 which is supplied with pressure fluid from an appropriate source.
- the head 304 also has at its opposite side from the throat 292, a throat 392 adapted to receive drill collars, and a gate 393 is pivoted on the head so as to be actuated between open and closed position by a double acting actuator 396.
- the head 304 will receive a pipe stand DP in its throat 292 when the pipe stand is elevated in the derrick and rests at its lower end on the dolly 12, as shown in full lines in FIG. 14, and that the carriage 284 and arm 28] can then be shifted to the broken line position. Thereafter, when the pipe stand DP is connected to the drill string, the gate 293 can be opened to allow the head to be retracted and to clear the pipe stand as the head is returned to the standby position, awaiting the next pipe stand.
- the carriage 284 and arm 281 can also be reversely operated to move the pipe stand DP from the broken line position to the full line position.
- the head 304 can be manipulated or shifted in the compound directions necessary to move the lower end of a drill collar between the receptacle 106 at a selected location and the center of the derrick, while the upper end of the drill collar is suspended by the hoist equipment or is engaged in the finger board 105.
