METHOD AND APPARATUS TO POSITION AND PROTECT CONTROL LINES BEING COUPLED TO A PIPE STRING ON A RIG

The present invention concerns a system for installing one or more control lines secured to a tubular string suspended in a borehole comprising: a first arm having a pivotally secured first end about which a second end is rotatable with a generally vertical plane; a second arm having a first end pivotally coupled to the second end of the first arm and a second end coupled 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 one or more cylinders for rotating the first arm and for translating and rotating the second arm within the vertical plane to move the control line retainer along a generally vertical path along the tubular string.
