Description

The present invention relates to a device and a method for handling drill pipes, ie pipes, rods and linkage trains for drilling rigs and drilling rigs, in particular for sinking boreholes on hydrocarbon deposits or for geothermal energy.

Drilling on hydrocarbon deposits, ie z. B petroleum or natural gas, are usually sunk discontinuously, since after drilling a boom length of drilling must be interrupted to combine with the drill string another linkage, with which the drilling process is then continued. Discontinuing is also the removal of the drill pipe or the installation and removal of casing casings, as each time the process must be interrupted in order to connect or disconnect the corresponding pipes or drill rods with the drill string or the casing string. Usual boring bars reach approximately nine meters in length, a double or triple boom train, respectively, about eighteen and twenty-seven meters respectively.

Due to increasing cost pressure, operators of drilling rigs are faced with the need to replace the discontinuous process of drilling bores or pulling drill pipes and piping by a quasi-continuous process.

Accordingly, it is an object of the invention to provide an apparatus for handling drill pipe for a drilling rig and a method of operating such a device with which the supply of drill pipe to the drilling rig is facilitated.

This object is achieved in a first variant by a device having the features of claim 1 and in an alternative variant by a device having the features of claim 6. According to the first variant it is provided that in a device for handling drill pipe for a drilling rig at least one boom magazine (rod storage device) a Gestängemagazinwegs is slidably movable and that acts as Gestängemagazinweg a so-called Skiddingbahn, in particular a Skiddingbahn with two parallel strands of several juxtaposed Skiddingmatten ,

The use of a skidding track for relocating a drilling rig and the construction of a skidding track of attachable skidding mats are known per se. The individual Skiddingmatten are elongated, plate-shaped metal structures, which have a corresponding load, namely z. As the drilling rig, can record, but also to absorb tensile loads, as they arise when moving or moving the rig, are suitable. The skidding track with its two parallel strands acts essentially like a rail train on which the rig is movable. The drilling rig rests with sliders on the two strands of Skiddingbahn, and with the Skiddingbahn on the one hand and a lower base portion of the drilling rig on the other hand hydraulic elements are connected, which cause on actuation, pulling or pushing the rig on the Skiddingbahn along the longitudinal extent.

The invention, with its aspect stated in the first independent device claim, aims at the use of means already known for moving the drilling rig, namely the skidding track, also for use in moving one or more boom magazines. By virtue of the fact that one or more boom magazine (s) is / are movable, a boom magazine can be moved to a transfer or transfer position, as required, in which drill pipe can be transferred to or taken over by the drilling rig. The fact that a complete rod magazine is movable in this transfer position, eliminating the previously required individual handover or takeover of drill pipe or a supply or removal of drill pipe in larger quantities, but not in the amounts as they move in accordance with the inventive approach rod magazines can be kept.

As a linkage magazine in particular a combination of two spaced juxtaposed and mutually fixed stage elements comes into consideration. The distance between these stage elements is chosen so that a loading and unloading of the boom magazine with a handling device like a forklift or the like is possible.

The above object is also achieved with the features of the second independent device claim. Thereafter, in a device for handling drill pipe for a drilling rig, it is provided that at least one boom magazine, in particular a boom magazine of the above type, is displaceably movable along a boom magazine path, that a boom handling device can be moved transversely to the boom magazine travel along a handling device path and that the handling device travel is at least sections movable together with the rod magazine.

In this embodiment, the advantage also comes into play that a complete rod magazine is movable in a transfer or transfer position. To transfer or takeover is a linkage handling device, z. As a gantry crane or the like, is provided, with the result for this device, the peculiarity that a provided as a travel handling device path is at least partially movable with the rod magazine. This results in a fixed position of at least the portion of the handling device path to the respective boom magazine. A movable on the handling equipment rod handling device can operate without additional adjustment or the like the rod magazine in the sense of removing or dropping drill pipe.

The dependent claims are directed to preferred embodiments of the present invention. The claims filed with the application are formulation proposals without prejudice to the achievement of further patent protection. The Applicant reserves the right to claim further feature combinations previously disclosed only in the description and / or drawings. Relationships used in subclaims indicate the further development of the subject matter of the independent claim referred to by the features of the respective subclaim; they may also contain independent inventions having a design independent of the objects of the preceding claims and are not to be understood as a waiver of the provision of independent, objective protection for their features or the feature combinations of the dependent claims. Furthermore, with a view to an interpretation of the claims in a closer specification of a feature in a subordinate claim, it is to be assumed that such a restriction does not exist in the respective preceding claims.

If the here and described below described apparatus for handling drill pipe for a drilling rig together with the respective drilling rig or displaced, there is a favorable situation with respect to the mitwandernden along with the drill storage location of the drill string or a portion of the drill string, namely in the Device belonging linkage magazines. If the displacement of the device with the drilling rig takes place in the sense of a simultaneity, the drill pipe is at the end of the movement process immediately available for the continuation of the drilling operation at the new position. The movement of the drill pipe handling device and the parallel movement of the drilling rig may even be synchronized so as to permit transfer of drill pipe to the drilling rig or transfer of drill pipe from the drilling rig during the movement process.

If in a device for handling of drill pipe without a separate rod handling device for the boom magazine a slope along an axis extending to Gestängemagazinweg axis is changeable, can be located with such a change in inclination in the boom magazine drill pipe to one side of the rod magazine by the drill pipe according to Tilt rolls in this direction. The thus effected positioning of the drill pipe within the boom magazine allows its transfer to the drilling rig and at an opposite inclination takeover of the drilling rig, so that according to the inclination, the assumed drill pipe rolls away from the transfer position and this is thus free again.

It is advantageous with a change in inclination of the rod magazine located therein drill string conveyed to a deeper side of the boom magazine and can be received in this position by a vertical elevator. The vertical elevator already belongs to the drilling rig, namely to a base of the drilling rig acting as a working platform. The vertical elevator uses z. B. with pawls or the like laterally in the rod magazine and can record in this way drill pipe.

If the boom magazine path is bridged or bridged with a guideway, which is a driving over the Gestängemagazinwegs with a handling device, for. As a forklift or the like, allows a rod magazine can also be equipped on the rod magazine path with drill pipe or such drill string is removable with such a handling device.

When at least two or all of the linkage magazines that can be arranged on the linkage magazine path are coupled, such that a movement or displacement of a linkage magazine concerns all coupled linkage magazines and between each two coupled linkage magazines a handling device travel element movable with the linkage magazines is arranged as a section or at least as a possible section of the handling device path, or is disposed between each two coupled linkage magazines and each on the outer sides of a first and a last coupled linkage magazine with a movable handling device Wegelementes this is a section of Handling device along with the coupled rod magazines mobile. Depending on which of the coupled linkage magazines is moved into a transfer position, with the movement of this magazine into the transfer position, movement of at least one handling device path element to this transfer position, ie to a position or to positions laterally from the transfer position, takes place directly. With the or each handling device path element at the transfer position, the handling device can be moved at the transfer position above the transfer magazine located in the transfer rack, so that a removal or removal of drill pipe is possible.

When the handling path in the form of at least one handling device path member or a pair of handling path members at least in the region of the transfer position extends laterally beyond the boom magazine path and forms a handling device waiting position, the handling device can be moved to this position when a rack magazine or coupled rack magazines are moved onto the boom magazine path. The handling device then remains stationary during the complete movement phase of the or each rod magazine. Furthermore, the handling device remains independent of the movement of the or each rod magazine in the transfer position, so that on the one hand the handling device when moving the or each rod magazine does not have to be transported and on the other hand, the availability of the handling device is maintained in the transfer position.

When the or each walker path member is stationary in the region of the handling device waiting position in operation of the apparatus described hereinbelow and when displacing the or each boom magazine, particularly at the end of the shifting process, the or each traveling handler path member is positionally aligned with the or each handler path member of the handler waiting position itself with the aligned arrangement at the end of the movement process as a travel path for the handling device usable transition between the stationary and the co-moving Handlingseinrichtungswegelementen so that the handling device from the handling equipment waiting position out and again on the now in the transfer position located rod magazine is movable.

As Gestängemagazinweg is a Skiddingbahn into consideration, in particular a Skiddingbahn with two parallel strands of several lined Skiddingmatten. The use of a skidding track as a linkage magazine path has the advantage that identical components can be used for the movement of the device described here and hereinafter for handling drill pipes as well as for the displacement of the entire drilling rig by "skidden". This reduces development, production and maintenance costs through the use of the same common parts. As a rod magazine, the use of two spaced apart side by side and fixed to each other stage elements comes into consideration. Two stage elements are particularly suitable for the storage of drill pipes, in which two individual elements are already combined by conventional screwing (a so-called "double" / "double-stand"), wherein each stage element substantially receives a portion of the double linkage element. In addition, the use of two juxtaposed fixed stage elements is advantageous because thereby sufficient space remains between them, so that access with a handling device in the manner of a forklift remains possible and accordingly the rod magazine can be loaded or unloaded with this.

As a boom handling device, a gantry crane or any type of crane suitable for lifting and for at least lateral movement of drill pipe is considered. The use of a gantry crane has the advantage that it can carry high loads on the one hand because of its substantially vertically loaded columns and with appropriate design of the crane bridge and on the other hand structurally relatively inexpensive. In addition, when using a gantry crane, the drill pipe can be moved along all Cartesian coordinate axes: the vertical mobility allows the drill pipe to be picked up and removed in the boom magazine or vertical lift. A horizontal direction of motion allows the process to be in or out of the hauler wait position, above the boom magazine, and from or to the vertical elevator. An optional horizontal movement option, perpendicular to this last direction of motion, allows accurate adjustment of drill string packages in the boom magazine. With appropriate execution of a gantry crane as a rod handling device, ie at a corresponding height of such a gantry crane, in individual cases, the gantry crane can take over the function of the otherwise separately required vertical elevator with, so z. B. drill pipe in the field of soil level from a rod magazine and at the level of functioning as a working platform base of the drilling rig, the so-called Drillfloor, drop or there to a possibly extendable or otherwise to Formation of a takeover position Passed suitable transfer facility.

As a handling device path element is a rail or a contactable in the manner of a rail for traversing profile element, z. As a T-beam, a double-T-beam, a U-rail or the like, into consideration.

If the boom magazine with holding bars, so-called stanchions, is divided into separate sections and drill pipe from these or in this by the linkage handling device according to a predetermined or predetermined sort order can be removed or stored, the degree of automation in feeding and removing drill pipe or from the drilling rig. In addition, in a manual operation of the boom handling device defective drill pipe or drill pipe, the z. B. has reached predetermined tolerance values with respect to its duration of use, are stored so that on the one hand a maintenance and repair or removal for such maintenance and repair allows and on the other hand unintentional reuse of the thus separated drill pipe is avoided.

The advantage of the alternative embodiment of the device for handling drill pipe, so the device with rod handling device, is mainly that with the rod handling device by method transverse to Gestängemagazinweg drill string is selectively transported from a respective rod magazine to a vertical elevator and vice versa. The vertical elevator, if its function is not taken over by the boom handling device, belongs to a base of the drilling rig functioning as a working platform. Without a vertical lift, ie with a gantry crane, which takes over the functionality of the boom handling device and at the same time the functionality of a vertical lift, the position for transferring or transferring drill pipe to the drilling rig or from the drilling rig is at the level of the working platform.

The inventive method for operating a drilling rig as described here and below is characterized in that as required a rod magazine or more coupled rod magazines are moved to the Gestängemagazinweg and passes in this way each rod magazine with a required drill string in a transfer position, in a Removal of drill pipe from the boom magazine or a placement of drill pipe in the boom magazine is possible. The apparatus for handling of drill pipe can be moved together with the drilling rig, so that there is a variable, non-stationary transfer position, which is dependent only on the position of the drilling rig.

In a drill pipe handling apparatus comprising a boom handling device and in which the handling path forms a handling device waiting position, a favorable method is characterized in that at least two or all of the boom magazines on the boom magazine path are coupled such that movement or displacement of a boom magazine all coupled rod journals, that between each pair of coupled rod magazines with a movable handling device path element is arranged or between two coupled rod magazines and at least on an outer side of a first or a last rod magazine a movable handling device Wegelement is arranged, and that for moving a rod magazine in the transfer position or from the transfer position, first the linkage handling device into the handling device waiting position is moved, then moving the linkage magazines takes place, until at least one moving handling device Wegelement aligned with the, or in two moving Wegelementen, each the handling device waiting position forming handling device Wegwegelement are positioned. The handling device waiting position enables the method of the boom handling device to a fixed position even when moving the rod magazines, so that the rod handling device must not be moved together with the rod magazines and is still available at the end of the movement in the transfer position. When the or each co-moving handler path member is positioned at the end of the travel operation in alignment with the or each handler waiting position handler path member, the link handler may again be moved over the now in transfer position rod magazine and pick up or drop drill string immediately thereafter.

The handling device path, depending on the configuration of the linkage handling device, comprises a track or two parallel tracks, which are each formed from at least one handling device path element. The required number of lanes is also provided for the haulage waiting position. An aligned arrangement of two tracks, so an aligned Arranging the at least two handler path elements forming the handler waiting position with the corresponding handler path elements moved along with the combined boom magazines is facilitated by the spacing of the path elements in the waiting area being identical to the distance of the path elements to the right and left of a boom magazine, because only so Driving with a gantry crane is possible as a rod handling device.

To facilitate the transition between the movable handling device path elements and the stationary handling device path elements of the handling device waiting position, it may be provided that the corresponding path elements have profiles for receiving connecting pieces on their mutually facing sides, so that without such a connecting piece and thus during movement of the rod magazines and the path elements coupled thereto a clearance acting as a safety gap remains between stationary and movable handling means path elements.

Overall, the invention finally also relates to a use of a skidding track for moving boom magazines and / or for moving boom magazines together with a drilling rig that is also movable along a skidding track. The use of a skidding track already known for moving drilling rigs has not hitherto been considered for the movement of boom magazines. When using a Skiddingbahn (also) for moving rod magazines resulting in the above-mentioned advantages in terms of reduced development, production, storage and maintenance costs due to the consistently usable common parts. When using a Skiddingbahn for moving linkage magazines results in an additional advantage that the movement of the linkage magazines then corresponds to the movement of the rig, so that the two movement processes are easier to synchronize, for. B. by a correspondingly controlled or regulated control of the required hydraulic units. Finally, the use of a skidding track to move boom magazines allows for the movement of large loads, as already proven when moving a complete drilling rig on a skidding track, so that boom magazines are movable with a degree of filling that was immovable with previous means. In this way, also rod magazines with double or triple linkage elements are movable, so that drill pipe in the form of such combined elements directly fed to the rig and accordingly results in an increase in efficiency in the operation of the rig, because the number of previously required combination operations individual linkage elements is reduced.

An embodiment of the invention will be explained in more detail with reference to the drawing. Corresponding objects or elements are provided in all figures with the same reference numerals.

The or each embodiment is not to be understood as limiting the invention. Rather, numerous modifications and variations are possible within the scope of the present disclosure, in particular those variants, elements and combinations and / or materials, for example, by combination or modification of individual in conjunction with those in the general description, the or each embodiment and the claims described and contained in the drawings features or elements or method steps for the skilled in the art with regard to solving the problem and lead by combinable features to a new subject or to new process steps or process steps, even if they are such. B. work procedures.

In this way are both units, namely drilling rig 10 and the device for handling drill pipe with boom magazine path 24 and the or each movably movable rod magazine 20 . 22 , together relocatable.

1 shows in terms of rod magazines 20 . 22 in that the two illustrated rod magazines 20 . 22 coupled with each other, so that a movement or displacement of a linkage magazine 20 . 22 all coupled rodent magazines 20 . 22 concerns. Basically, there are more than two boom magazines 20 . 22 , so three, four, five, etc. rod magazines 20 . 22 coupled. For coupling the linkage magazines 20 . 22 are in the in 1 illustrated embodiment coupling rods 30 intended. The rod magazines 20 . 22 themselves are in the illustrated embodiment with two spaced juxtaposed and fixed to each other stage elements 32 executed. For fixing the stage elements 32 with each other are fixation rods 34 intended.

2 shows the situation according to 1 in a side view in a sectional view. In this illustration, it can be seen that below the working platform 14 a so-called blow-out preventer 36 However, this is irrelevant to the understanding of the invention. In the side view it can be seen that for a rod magazine 20 . 22 its inclination along a lengthwise to Gestängemagazinweg 24 extending axis is changeable. For this comes z. B. acting as an axis of rotation axis element and a remote from the axis actuator, for. As a hydraulic cylinder, a rotary spindle or the like, into consideration. With a change in inclination of the linkage magazine 20 . 22 is drill pipe located therein 16 . 18 to a deeper side of the linkage magazine 20 . 22 be conveyed. In this position is the drill string 16 . 18 from one to the work platform 14 belonging vertical lift 38 received.

The vertical elevator 38 is in 1 also in its position on one of the handling device for drill pipe 16 . 18 facing side of the platform 14 recognizable.

B. in the between two stage elements 32 ( 1 ) remaining gap in a rod magazine 20 . 22 and can drill pipe in this way 16 . 18 take up. Recorded drill pipe 16 . 18 is with the vertical lift 38 up to a working level of the working platform 14 can be transported and is there in a known manner, for. B. with a so-called pipehandler 42 , turned.

3 shows in a plan view a situation basically as in 1 shown. In the plan view one recognizes particularly well the linkage magazine way 24 in its execution as Skiddingbahn 26 with the two parallel strands of multi-row Skiddingmatten 28 , Also clearly visible in the plan view, that the rod magazines 20 . 22 from spaced apart adjacent and fixed to each other stage elements 32 are formed. For fixing the stage elements 32 with each other are fixation rods 34 intended.

In addition to the situation in 1 is in 3 shown that the rod magazine path 24 with a one driving over with a handling device, eg. B. a forklift 44 , allowing driveway 46 can be bridged. In the situation shown is the track 46 for easier accessibility around a ramp 48 added. With a handling device like a forklift 44 can drill pipe 16 . 18 individually or in smaller boxes 50 the drilling rig 10 be supplied.

The driveway 46 also allows (not shown) access with the handling device on the rod magazines 20 . 22 , z. B. for removing or laying down drill pipe 16 . 18 , If necessary, for such access and before attaching the guideway 46 fixing bars 34 or the like between the stage elements 32 a linkage magazine 20 . 22 to remove.

In 3 are the two rod magazines shown 20 . 22 not coupled, so that it can be seen that each on the linkage magazine path 24 located rod magazine 20 . 22 also individually movable movable, here z. B. to the driveway 46 between two rod magazines 20 . 22 to attach and a feeder one compared to the rod magazines 20 . 22 smaller box 50 to the drilling rig 10 to allow.

4 shows one in comparison to the situation according to 1 alternative embodiment of the device for handling drill pipe 16 . 18 for a drilling rig 10 , From the known drilling rig 10 is in 3 only part of the platform 14 with the vertical elevator provided there 38 shown. The embodiment according to 4 corresponds to that according to 1 insofar, as a rod magazine 20 . 22 for drill pipe 16 . 18 namely boring bars 16 and casings 18 , are provided. As rod magazines 20 . 22 function as in the embodiment according to 1 two spaced apart juxtaposed and fixed to each other stage elements 32 , wherein the fixation of the stage elements 32 with each other with fixing rods 34 he follows. The rod magazines 20 . 22 are also coupled to each other and shown here coupled, so that a movement or displacement of a linkage magazine 20 . 22 all coupled rodent magazines 20 . 22 concerns. For coupling the linkage magazines 20 . 22 are in the in 4 illustrated embodiment coupling rods 30 intended. 4a shows a first section of the illustration in 4a with one of the rod magazines 20 . 22 , 4b shows a further section from the illustration in 4a with another rod magazine 20 . 22 ,

Each rod magazine 20 . 22 is also at the in 4 illustrated configuration along the boom magazine path 24 movable movable. As Gestängemagazinweg 24 acts as well as in the embodiment according to 1 , a skidding track 26 with two parallel strands of multi-row Skiddingmatten 28 ,

Unlike the embodiment according to 1 and 2 is for the removal or removal of drill pipe 16 . 18 in the linkage magazines 20 . 22 not or at least not exclusively a variability of the inclination of the linkage magazine 20 . 22 along a lengthwise to Gestängemagazinweg 24 extending axis provided. The removal or removal of drill pipe 16 . 18 in the linkage magazines 20 . 22 takes place at the in 4 illustrated embodiment with a rod handling device 52 , in the 4 as a gantry crane 54 is shown. The use of a gantry crane 54 as a rod handling device 52 comes especially into consideration when in the rod magazine 20 . 22 are formed with upright support rods, stanchions or the like portions. The sections thus formed allow the separated deposition of drill pipe 16 . 18 , The linkage handling device 52 is transverse to the rod magazine path 24 along a handling path 56 traversable. In addition, the handler path is 56 at least in sections with the at least one movable rod magazine 20 . 22 or, in coupled linkage magazines 20 . 22 , with each coupled rod magazine 20 . 22 movable.

With the mobility of the rod magazines 20 . 22 on the rod magazine path 24 and with the agility of the handling equipment path 56 together with one or more coupled linkage magazines 20 . 22 is also the in 4 illustrated device for handling drill pipe 16 . 18 together with the drilling rig 10 movable, and due to the ability to align the Skiddingmatten 28 in the illustrated embodiment, as the linkage magazine path 24 functioning skidding track 26 form the device is also together with the drilling rig 10 ( 1 ) relocatable.

The handling device path 56 is passed through one or more handler path elements 58 educated. As a handling device path element 58 In this case, a rail or a profile element that can be contacted in the manner of a rail for movement movements acts. In 4 are as handling means path elements 58 waiving unnecessary details rail sections shown.

In 4 At least two are on the rod magazine path 24 arranged rodent magazines 20 . 22 coupled, making a movement or relocation of a linkage magazine 20 . 22 all coupled rodent magazines 20 . 22 concerns. Between two coupled linkage magazines 20 . 22 is one with the rod magazines 20 . 22 movable handling device path element 58 as a section or, depending on the position on the boom magazine path 24 at least as a potential section of the handling equipment path 56 arranged. The one with the or each on the rod magazine path 24 movable rod magazine 20 . 22 co-moving handling means path elements 58 allow a method of the boom handling device 52 over a complete depth of the respective linkage magazine 20 . 22 ,

With only one rod magazine 20 . 22 on the rod magazine path 24 eliminates the need for a coupling with an adjacent rod magazine 20 . 22 so that the handling path elements 58 with coupling rods 30 almost in front of and behind the respective rod magazine 20 . 22 be arranged and fixed there. For several coupled boom magazines 20 . 22 there is ever a Handlerwegwegwegelement 58 between two adjacent boom magazines 20 . 22 and one handler path element each 58 in front of coupled linkage magazines 20 . 22 and behind the coupled linkage magazines 20 . 22 , The distance between two along the boom magazine path 24 adjacent handling device path element 58 is always consistent. In order to ensure such a constant distance, especially with different sized rod magazines 20 . 22 , Coupling rods 30 and / or fixation rods 34 be provided in different lengths, so that depending on the respective rod magazine 20 . 22 with a suitable selection of coupling rods 30 and / or fixation rods 34 the necessary constant spacing between adjacent handling means path elements 58 can achieve.

In one embodiment of a boom magazine path 24 that does not involve a paired, parallel array of handling path elements 58 is formed and accordingly manages with only one rail track or only one profile element strand, correspondingly eliminates the need for only a movable rod magazine 20 . 22 or with several coupled boom magazines 20 . 22 on both outer sides each a handling device path element 58 provided. However, the description will be made according to the embodiment in FIG 4 continued. For a boom handling device 52 in the manner of a gantry crane 54 or the like, with its two lateral supports on a handling device path 56 with two parallel strands of handling means path elements 58 can be moved, there is a sufficient stability of the rod handling device without special design effort 52 and one for handling the drill pipe 16 . 18 sufficient load-bearing capacity.

The linkage handling device 52 is used for handling drill pipe 16 . 18 above the respective rod magazine 20 . 22 positioned so as to receive or deposit drill pipe 16 . 18 is possible. For passing drill pipe 16 . 18 to the drilling rig 10 is a recording of drill pipe 16 . 18 from the respective rod magazine 20 . 22 intended. For this purpose, the linkage handling device lowers 52 Means for picking up drill pipe 16 . 18 on this. As a means of picking up drill pipe 16 . 18 comes z. As a crane with an electromagnet, a gripper or the like into consideration. After receiving drill pipe 16 . 18 this is first raised until a height is reached, which is a method of the boom handling device 52 on the haulage path 56 allowed. Once a corresponding height is reached, the linkage handling device 52 on the haulage path 56 towards the drilling rig 10 , especially in the direction of the other at the work platform 14 provided vertical lift 38 to be traded. Once a position in front of the vertical elevator 38 is reached, carried out with the linkage handling device 52 a drop of the recorded drill string 16 . 18 on or in the vertical lift 38 , This position is accordingly referred to as the transfer position. Based on this, the transfer position is also a position of a boom magazine 20 . 22 referred to in this from a removal of drill pipe 16 . 18 and a handover to the drilling rig 10 is possible. When adopting drill pipe 16 . 18 from the drilling rig 10 the movement sequence described above takes place in the reverse order.
