Abstract

The inventions relates to an apparatus for connecting a control line to a tubular string. In one embodiment, the apparatus includes a guide boom pivotable around a location adjacent the string and with a guide member at an end thereof to guide the control line. The apparatus further includes a clamp boom that is independently pivotable and includes a clamp housing at an end thereof for clamping the control line against the tubular string. The guide boom and the clamp boom each have a center line which is substantially aligned with the center line of the tubing string permitting the control line to be aligned adjacent the tubular string prior to clamping.

Claims

17. A method of operating a control line positioning apparatus comprising:

moving a control line holding assembly from a staging position to a clamping position, wherein the control line holding assembly is operatively mounted proximate a floor of a rig with a mounting assembly;

holding a control line adjacent a tubular string with the control line holding assembly;

securing the control line to the tubular string; and

relocating the control line holding assembly away from the tubular string.

18. The method of claim 17, wherein the control line holding assembly and the mounting assembly are connected by an arm that extends at an angle relative to the rig floor.

19. The method of claim 17, further including a clamp holding assembly.

20. The method of claim 19, further including moving the clamp holding assembly through an arc describing at least 100 degrees.

22. The method of claim 17, wherein the clamp holding assembly includes a clamp.

23. The method of claim 22, further including positioning the clamp over a coupling in the tubular string.

24. The method of claim 17, further including sensing an operative condition of at least one other tubular handling device of the rig and controlling the control line holding assembly in response to the sensed operative condition.

25. The method of claim 24, wherein the controlling is achieved by automatic feedback of the sensed operative condition into a control system.

26. The method of claim 17, further including sensing an operative condition of the control line holding assembly and controlling at least one other tubular handling device of the rig in response to the sensed operative condition.

27. The method of claim 26, wherein the controlling is achieved by automatic feedback of the sensed operative condition into a control system.

21-1. The method of claim 21, further including extending the second arm relative to the first arm.

28. A method for running a well pipe into a well with control lines attached to the pipe, comprising:

securing a pipe with a spider located above a rig floor;

providing a control line alignment apparatus having a mounting member, a control line engagement member and a motive member for moving the engagement member relative to the mounting member;

using the control line alignment apparatus to align the control line with the pipe at a location below the spider and above the rig floor;

securing the control line to the pipe below the spider; and

lowering the pipe and secured control line into the well.

29. The method of claim 28, wherein the control alignment apparatus further includes an arm for connecting the control arm engagement member to the mounting member.

30. The method of claim 29, wherein the arm is angled at least 45 degrees relative to the rig floor.

31. The method of claim 30, wherein the control alignment apparatus further includes a clamp holder assembly for securing the control line to the well pipe.

32. The method of claim 31, further including rotating the clamp holder through an arc describing at least 100 degrees.

33. A method of aligning a control line with a tubular, comprising:

positioning a control line using a remotely controllable head;

determining a position of the head, wherein the position of the head aligns a first portion of the control line with a tubular string;

memorizing the position of the head; and

positioning a second portion of the control line using the memorized position.

34. The method of claim 33, wherein the remotely controllable head is attached to a rig floor by an arm that extends at an angle relative to the rig floor.

35. The method of claim 34, wherein the angle relative is at least 45 degrees.

36. The method of claim 33, further including securing the control line to the tubular.

37. An apparatus for positioning a control line adjacent a tubular string, the apparatus comprising:

a guide boom pivotable around a location adjacent the tubular string, the boom including a guide member at an end thereof to guide the control line; and

a clamp boom independently pivotable from substantially the same location as the guide boom, the clamp boom having a clamp assembly at an end thereof for clamping the line against the tubular.
