Detailed description of the invention
Referring to Fig. 1, a driving arrangement 2, the elongated member that is hollow pipe 4 forms for driving enters seaThe end,, as the part of drilling or getting in core operation, it has a body 6 being supported on mobile device,Described mobile device is a pair of track of installing and being controlled by hydraulic power unit 12 (Fig. 5) around axle 108 form. In the diagram more in detail of Fig. 4 and Fig. 6, described track 8 can be at an extended position separately12 and retracted position 14 between move on axle 10 with respect to described body 6.
The drilling cramp 16 with a probing motor 18 is supported by the bracing or strutting arrangement that is support arm 20 forms, therebyThe position of described drilling cramp 16 is adjustable with respect to described body 6. This can grasp in probing described drilling cramp 16In work, be positioned at the top of a well control module 38 (Fig. 3) or preventer, or getting core direct position of when operationOn sea bed (Fig. 2). Described drilling cramp 16 also can be parallel to advancing of described driving arrangement 2 substantially around oneThe axis 22 (Fig. 5) of direction rotates.
Described pipeline 4 is arranged in the positioner that is pipe box 24 forms that are supported on described body 6,And described body 6 has the frame 26 of a support one detachable hoist point 28, described detachable hoist point 28Substantially be positioned at the top of the center of gravity of described driving arrangement 2, with the ship (not shown) that enables to be positioned at sea fromDriving arrangement 2 described in deploy. Described 26 definition one hole 30 (Fig. 4), for making described pipe box 24Can be positioned at described body 6 rears by described hole 30 from one by a pipe box transfer member (not shown)Position 32 is delivered to a position 34 that is positioned at described body 6 fronts. Be pipeline transfer member 40 (Fig. 7And Fig. 8) conveying device of form laterally carries each pipeline 4 to enter described drilling cramp 16. Be a control armThe manipulation device of 36 forms unloads blank pipe deferent box 24 from described body 6, and by described pipe box 24Be arranged on one above near the suitable support (not shown) of described body 6 on sea bed, this has limited subsequentlyMigration before described blank pipe box 24 embed the degree of sea bed. The probing motor 18 of described drilling cramp 16 subsequentlyDrive described pipeline 4 to enter sea bed through well control module 38 (Fig. 3) or preventer in drilling operation,Or directly enter sea bed (Fig. 2) getting in core operation. The operation of described driving arrangement 2 is from being positioned at seaShip (not shown) upper controlled by a umbilical cable (not shown).
Referring to Fig. 7 and Fig. 8, described pipeline transfer member 40 comprises pair of pipes box unload arm 42, described pipeBox unload arm 42 is rotated for a retract pipeline 4 and the rotation axis 44 that rotates of the pipe box 24 from being positioned at position 34Through about 180 °, and discharge described pipeline 4 to described drilling cramp loading arm 46, to carry described pipeline 4Enter drilling cramp 16.
Next deployment, operation and the recovery of described driving arrangement 2 are described.
For from driving arrangement 2 described in waterborne vessel deploy to sea bed, the track 8 of described driving arrangement 2Return to the most at the beginning its retracted position 14 shown in Fig. 6 to minimize the width of described driving arrangement 2. WithTime, in order to minimize the length of described equipment 2, described drilling cramp 16 is positioned at its raised position as shown in Figure 1,Minimize whereby the size in the hole (being called as moon pool) on described waterborne vessel, described hole is for passing sea ice portionAffixing one's name to described driving arrangement 2 is necessary to sea bed.
Then described driving arrangement 2 is fallen by a carrying cable (not shown) that is connected in hoist point 28Be low to moderate on sea bed, here in the time that described driving arrangement 2 is lowered due to the mobile quilt of described driving arrangement 2Be positioned to minimize, described well control module 38 to be caused to damage from the enough distances of described well control module 38Risk. Before the track 8 of described driving arrangement 2 contacts with sea bed formation, they pass through hydraulic powerUnit 12 outwards moves to their extended positions 12 as shown in Figure 4 from described body 6, drives described in thenMoving equipment 2 moves to the position near described well control module 38 by its track 8. DescribedThen drilling cramp 16 is reduced to and described well control module 38 combinations by described control arm 36.
When described drilling cramp 16 forms combination with described well control module 38, each pipeline 4 is defeated by pipelineSend member 40 to shift out and laterally deliver into subsequently described brill from being positioned at the pipe box 24 of anterior position 34Frame 16. Described hydraulic power unit 12 drives described probing motor 18, and described probing motor 18 impels instituteStating pipeline 4 is passed down through described well control module 38 or directly enters sea bed. Described pipeline 4 is subsequently with thisThe mode of kind is driven into sea bed, is moved sky, described control arm until be positioned at the pipe box 24 of anterior position 34Then 36 unload this blank pipe box 24 from described body 6, and it is arranged on sea bed near described body 6One suitably support (not shown), to carry out follow-up withdrawal. This pipe box 24 is subsequently by with respect to describedBody 6 is fed forward, thereby the place of this blank pipe box 24 is occupied by a full pipe box 24, and process continue intoOK. Then the position 32 of being vacateed by the pipe box 24 at rear can be filled by a full pipe box 24 again.
When described probing or after getting core and having operated, described in being returned to blank pipe box 24, drives described control arm 36On the body 6 of moving equipment 2, to be retracted to waterborne vessel.
Those skilled in the art know, and above embodiment only describes by way of example, but does not have any restrictionMeaning, do not depart from the defined scope of the present invention of the claim of enclosing, can make multiple change andModification.
