Abstract
A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider that is normally mounted on the rig floor is supported by a table elevated above the rig floor. Supporting the spider on an elevated table provides personnel with access to a portion of the length of the pipe string below the elevated spider and above the rig floor for applying a fastener to secure the control line to the pipe string. The control line is supplied from above the spider and is positioned by a control line guide supported on the spider or a sleeve to pass through the spider outside the path of the pipe gripping members, such as slips.
