Patent attributes
Systems, devices, and methods include a racker device and a catwalk structurally arranged to move a tubular or stand about a drilling rig site. A sensing arrangement is cooperatively associated with at least one of the racker device and the catwalk and is configured to sense an aspect of a tubular while the tubular is being handled at the drilling rig and output a signal representative of the aspect of the tubular. A tubular validation system is configured to receive the sensed aspect of the tubular obtained by the sensing arrangement and determine a specification characteristic of the tubular based on the sensed aspect. This may be compared to specification standards to determine whether the tubular or stand should be discarded.
