Abstract
A protection tool is provided to protect a control line in a safe area while one or more slips of a spider are being closed. In another embodiment, a safety interlock system is provided to prevent the closing of the slips before the control line is pulled away from the tubular string. In yet another embodiment, a safety interlock system includes a safety interlock trigger adapted to be actuated by a protection tool. The safety interlock trigger is adapted to detect the physical presence of the protection tool, and thereafter send a signal to the interlock system to enable an operator or a control mechanism to safely close the slips.

24. A safety interlock system for controlling operation of a gripping element to prevent damage to a control line, comprising:
-
an interlock controller adapted to allow or prevent movement of the gripping element; and
an interlock trigger adapted to determine a position of the control line, wherein the interlock controller allows or prevents movement of the gripping element in response to a signal sent by the interlock trigger indicating the position of the control line. - View Dependent Claims (25, 26, 27, 28)

29. A tubular gripping member for use with a control line, comprising:
-
a slip; and
a sensing mechanism adapted to engage the control line, whereby engagement with the control line indicates that the control line is retracted from a path of travel of the slip. - View Dependent Claims (30, 31, 32)
