ABSTRACT:
When the spider slips are open, the control line can be moved toward the pipe string, can be clamped to the pie string and string and line can be lowered into the well. When the pipe connector approaches the spider, the spider slips need to be set. To move the control line into a safe area, it is thrust radially outward from the pipe string. The slips are closed while the line is retained outward.To keep them safe while work proceeds just above the spider an optional trap is closed to retain the control lines until the spider slips are opened. The lines can be manually pulled outward but it is more easily done with a powered thruster. Optional sequencing controls can start with moving the control line away from the pipe, closing the line trap, and closing the spider slips. Reversing the procedure, the sequencing controls open the spider slips, release the line trap, and moves the line toward the pipe.
