Control lines extend vertically through lateral spaces formed between a rig floor and a pipe holding assembly supported on the rig floor. A pipe string held by an elevator extends vertically through the pipe holding assembly into the well. The pipe holding assembly is raised vertically off of the floor, about the pipe string, to allow the control lines to be clamped to the pipe string below the pipe holding assembly. The invention permits the control lines to be clamped to the pipe string without passing through the pipe handling assembly to prevent damage to the control lines when the pipe handling assembly is closed to secure the pipe string.
