Abstract

An apparatus including a coiled tubing unit coupled to a drilling rig, and an enclosure surrounding the coiled tubing unit. The coiled tubing unit may include a coiled tubing reel and a coiled tubing injector, wherein the injector may move relative to the coiled tubing reel. The coiled tubing unit is configured to move relative to the drilling rig in both longitudinal and lateral directions.

Claims

1. An enclosed coiled tubing boat apparatus, comprising:

a structural framework;

a coiled tubing reel and an operatively associated coiled tubing injector; and

an enclosure that is operatively associated with the structural framework and that surrounds a portion of the coiled tubing reel and a portion of the coiled tubing injector to form the coiled tubing boat apparatus;

wherein the coiled tubing injector is configured to move within the coiled tubing boat apparatus and wherein the structural framework is adapted to be carried on a drilling rig, and

wherein the coiled tubing boat apparatus with the enclosure is configured to movably couple to the drilling rig for movement relative to the drilling rig when moveably coupled to the drilling rig.

2. The coiled tubing boat apparatus of claim 1, wherein and the coiled tubing boat apparatus is configured to move in at least two dimensions relative to the drilling rig.

3. The coiled tubing boat apparatus of claim 2, wherein the coiled tubing boat apparatus is coupled to a structural member layout on the drilling rig.

4. The coiled tubing boat apparatus of claim 2, wherein the coiled tubing boat apparatus is adapted to move between a non-operating, coiled tubing reel exchange position and an operating position, each on the drilling rig.

5. The coiled tubing boat apparatus of claim 4, wherein the non-operating coiled tubing reel exchange position includes a portion of the coiled tubing boat apparatus overhanging a rear of the drilling rig.

6. The coiled tubing boat apparatus of claim 4, wherein the operating position includes the coiled tubing boat apparatus positioned proximate a mast of the drilling rig.

7. The coiled tubing boat apparatus of claim 6, wherein the coiled tubing boat apparatus is adapted to move to a non-operational rig transport location on the drilling rig in which the coiled tubing apparatus is adapted to move laterally relative to the drilling rig to facilitate lowering of the mast of the drilling rig to an at least substantially horizontal position.

8. The coiled tubing boat apparatus of claim 1, further comprising a driller'"'"'s cabin that includes a plurality of controls to at least operate the coiled tubing injector, and hoist and lower a block of the drilling rig.

9. The coiled tubing boat apparatus of claim 1, wherein the enclosure is arranged to fully enclose both the coiled tubing reel and the coiled tubing injector.

10. The coiled tubing boat apparatus of claim 1, wherein the enclosure comprises separate rooms for the coiled tubing reel and for the coiled tubing injector.

11. A method of modifying an existing drilling rig which comprises:

installing a plurality of structural members on the existing drilling rig;

providing a coiled tubing boat apparatus which comprises;

a structural framework adapted to be associated with the plurality of structural members;

an enclosure surrounding at least a portion of the structural framework;

a coiled tubing reel protected within the enclosure; and

a coiled tubing injector protected within the enclosure;

wherein the coiled tubing injector moves between a non-operational position within the coiled tubing boat apparatus and an operational position; and

operatively associating the coiled tubing boat apparatus with the enclosure with the plurality of structural members so that the coiled tubing boat apparatus may move relative to the drilling rig when the coiled tubing boat apparatus is operatively associated with the drilling rig.

12. A method of operating a drilling rig which comprises:

providing a plurality of structural members on the drilling rig;

providing a coiled tubing boat apparatus which comprises a structural framework adapted to be associated with the plurality of structural members, the coiled tubing boat apparatus comprising an enclosure and carrying a coiled tubing injector movable within the enclosure of the coiled tubing boat apparatus and carrying a coiled tubing reel within the enclosure of the coiled tubing boat apparatus;

operatively associating the coiled tubing boat apparatus with the plurality of structural members so that the coiled tubing boat apparatus may move along the plurality of structural members relative to the drilling rig; and

moving the coiled tubing boat apparatus with the enclosure between an operating position and a non-operational, coiled-tubing-reel exchange position on the drilling rig when the coiled tubing boat apparatus is operatively associated with the drilling rig.

13. The method of claim 12, wherein moving the coiled tubing boat apparatus to the coiled-tubing-reel exchange position comprises moving the coiled tubing boat apparatus so that a portion of the coiled tubing apparatus overhangs a rear of the drilling rig.

14. The method of claim 12, wherein moving the coiled tubing boat apparatus to the operating position comprises moving the coiled tubing boat apparatus proximate a mast of the drilling rig.

15. The method of claim 12, further comprising moving the coiled tubing boat apparatus laterally relative to the drilling rig and on the drilling rig to facilitate lowering of a mast of the drilling rig to be lowered to at least a substantially horizontal position with the coiled tubing boat apparatus on the drilling rig.

16. The method of claim 12, which further comprises controlling a coiled tubing injector and hoisting and lowering of a block of the drilling rig from a driller'"'"'s cabin in the coiled tubing boat apparatus.

17. A coiled tubing boat apparatus comprising:

an operatively associated coiled tubing reel and coiled tubing injector;

wherein the coiled tubing injector is configured to move relative to the coiled tubing reel;

an enclosure surrounding at least a portion of both the coiled tubing reel and the coiled tubing injector to form the coiled tubing boat apparatus;

wherein the coiled tubing boat apparatus with the enclosure is integrally coupled with an existing drilling rig and configured to translate in at least two dimensions relative to the drilling rig when the coiled apparatus with the drilling rig.

18. The coiled tubing boat apparatus of claim 17 wherein the at least two dimensions includes longitudinal and lateral movement relative to the drilling rig.

19. The coiled tubing boat apparatus of claim 17, wherein the coiled tubing boat apparatus is supported by a structural framework that is operatively associated with a plurality of structural members connected to the drilling rig;

wherein the coiled tubing boat is installed on the plurality of structural members.

20. The coiled tubing boat apparatus of claim 18, wherein the coiled tubing boat apparatus is adapted to translate longitudinally relative to the drilling rig so that a portion of the coiled tubing boat apparatus overhangs a rear of the drilling rig in a non-operational position.

21. The coiled tubing boat apparatus of claim 17, which further comprises a driller'"'"'s cabin that includes a plurality of controls to at least operate the coiled tubing injector, and hoist and lower a block of the drilling rig.
