Arm for moving flexible lines at a well site
A movable arm 10 engages a flexible line 50 at a well site for positioning the flexible line between run-in position for passing the flexible line with a tubular through a well hole in the rig floor and a clamping position wherein the flexible line is adjacent the tubular above the rig floor for clamping the line to the tubular. The arm 10 extends upward from the rig floor 70 , and includes a line guide, such as roller 12 , for engaging the flexible line when in the run-in position. A powered drive 14 moves the arm between the run-in position and the clamping position. A spacer 82 may be used for positioning two or more flexible lines at a desired spacing relative to one another prior to positioning the lines within a clamp secured to the tubular. A slip bowl assembly 60 may be laterally movable so that slips do not engage the flexible line as it is run in the well.
