Abstract

An apparatus for retaining two strings of tubulars characterized in that said apparatus comprises body parts of a device for retaining a single string of tubulars and a converting member. A device for retaining a string of tubulars, said device comprising at least one body part having a curved tapered surface upon which inserts are located for engagement with said string of tubulars characterized in that said curved tapered surface comprises a recess for the passage of cables.

Claims

1. An apparatus for retaining a tubular, comprising:

a first passage and a second passage, wherein the first passage is larger than the second passage and the first passage having gripping members movable in the first passage adapted to retain the tubular and wherein the second passage is a recess formed in an inner wall of the first passage and is adapted to maintain a string outside a path traveled by the gripping members toward and away from the tubular.

2. The apparatus of claim 1, wherein the first passage is in communication with the second passage.

3. The apparatus of claim 1, wherein the string comprises a cable.

4. The apparatus of claim 3, wherein the apparatus comprises a spider.

5. The apparatus of claim 1, wherein the first passage comprises a tapered surface.

6. The apparatus of claim 1, further comprising a first body part and a second body part, wherein the first body part and the second body part are adapted to retain a tubular.

7. The apparatus of claim 6, wherein the first body part and the second body part are operatively coupled together.

8. The apparatus of claim 6, wherein the first body part and the second body part are hinged on at least one side.

9. The apparatus of claim 6, wherein the first body part and the second body part may be opened on two sides.

10. The apparatus of claim 6, wherein the apparatus comprises a spider.

11. A method of retaining a tubular and at least one connection member, comprising:

providing a tubular handling apparatus having gripping members, a first passage, and a second passage, wherein the second passage is a recess formed in an inner wall of the first passage;

moving the gripping members in the first passage to retain at least a portion of the tubular in the first passage;

maintaining the at least one connection member in the second passage while moving the gripping members to retain at least a portion of the tubular; and

running the at least one connection member substantially parallel to the tubular in the first passage.

12. The method of claim 11, wherein the at least one connection member comprises a cable.

13. The method of claim 12, wherein the tubular handling apparatus comprises a spider.

14. The method of claim 11, wherein the first passage comprises a tapered surface.

15. An apparatus for retaining a tubular, comprising:

a first body part and a second body part, wherein the first body part and the second body part are operatively coupled together to retain and support a weight of the tubular, and wherein the first body part and the second body part are openable on two sides to receive the tubular; and

a tubular passage and a groove, wherein the tubular passage is formed by coupling the first body part and the second body part and wherein the groove maintains a cable and is formed in a wall of the tubular passage.

16. A method for retaining a tubular and a cable, comprising:

providing a spider having a tubular passage, gripping members, and a recess;

installing the spider on a rig floor;

retaining a portion of the tubular in the tubular passage using the gripping members;

passing the cable through the recess and outside of a path traveled by the gripping members; and

connecting a tubular section to the tubular, thereby forming an extended tubular.

17. The method of claim 16, further comprising releasing the extended tubular from the spider.

18. The method of claim 17, further comprising:

lowering the extended tubular; and

retaining the extended tubular in the tubular passage.

19. The method of claim 16, wherein gripping members travel on a tapered surface of the tubular passage.

20. The method of claim 16, further comprising running the cable substantially parallel to the tubular.

21. The method of claim 16, wherein the tubular passage is accessible by the cable from the recess.

22. A method for retaining a tubular and a cable, comprising:

providing a spider having a bore and gripping members;

retaining a portion of the tubular in the bore using the gripping members; and

maintaining the cable in a recess in communication with the bore and outside a path traveled by the gripping members.

23. An apparatus for retaining a tubular, comprising:

a first body part operatively coupled to a second body part to retain and support a weight of the tubular, wherein the first body part and the second body part are openable on two sides to receive the tubular; and

a tubular passage and a groove, wherein the tubular passage is formed by coupling the first body part and the second body part and wherein the groove maintains a string and allows the string to pass through the apparatus, wherein the tubular passage is accessible by the string from groove.

24. The apparatus of claim 23, wherein the first body part is coupled to the second body part using a hinge member.

25. The method of claim 23, wherein the string comprises a cable.
