Abstract
An apparatus to attach a control line to a tubular member, in which the apparatus includes a control line arm having a first control line guide coupled thereto, and a base having a second control line guide coupled thereto, with the control line arm coupled to the base and movable with respect to the base. The control line arm may be movable between a raised position and a collapsed position with respect to the base, and the control line arm may be at least one of slidably coupled and rotatably coupled to the base.
Claims10
A method for installing a control line secured to a tubular string suspended in a borehole, the method comprising:
- moving a second control line arm from a collapsed position to a raised position with respect to a first control line arm to which a first end of the second control line arm is pivotally coupled thereby moving a control line adjacent to a first tubular string;
- guiding the control line with a control line retainer, wherein the control line retainer is coupled to a second end of the second control line arm;
- attaching the control line to the tubular string, and lowering the tubular string with the control line attached thereto further into the borehole from a rig floor;
- wherein the second control line arm engages a track at a position intermediate the first end and the second end of the second control line arm;
- and
- wherein an extension of one or more cylinders rotates the second control line arm within a vertical plane relative to the first control line arm and a base to move the control line retainer along a generally vertical path along the tubular string.
A method of manufacturing an apparatus for installing a control line secured to a tubular string suspended in a borehole, the method comprising:
- pivotally securing a first end of a first arm to a base and a second end of the first arm is rotatable with a generally vertical plane about the first end of the first arm;
- pivotally coupling a first end of a second arm to the second end of the first arm and coupling a second end of the second arm to a control line retainer;
- wherein the second arm slidably engages a track at a position intermediate the first end and the second end of the second arm;
- and
- providing one or more cylinders, wherein the one or more cylinders rotate the first arm and the second arm and translate the second arm within the vertical plane to move the control line retainer along a generally vertical path along the tubular string.
