Claim 19:
20. A system for conducting a subterranean operation, the system comprising:
a retention feature in a drill floor configured to suspend a tubular string from the drill floor via engagement of the retention feature with the tubular string;
an imaging system configured to capture images of a portion of the tubular string that extends above the drill floor, with the images containing a visible feature of the tubular string; and
a processor coupled to the imaging system and configured to detect a change in a relative position of the visible feature in the images while the tubular string is engaged with the retention feature, and
the processor configured to calculate a wear status of the retention feature based on the change in the relative position of the visible feature based on a comparison between the images of the relative position of the visible feature,
wherein a gripping force applied to the tubular string via the retention feature allows the change in the relative position of the visible feature while the tubular string is engaged with the retention feature and the wear status is greater than a pre-determined threshold of wear for the retention feature, or wherein the gripping force retains the tubular string in the retention feature when the retention feature is engaged with the tubular string and the wear status is less than or equal to the pre-determined threshold of wear for the retention feature,
wherein the processor is configured to calculate the wear status of the retention feature for each time the retention feature is engaged with the tubular string over a period of time, and wherein the processor is configured to determine an actual life cycle of the retention feature based on the calculated wear statuses.
