Patent ID: 8899319

Claim:
An automated tubular handling system adapted to make-up or break-out tubulars to or from a tubular string which comprises: a rotary drive adapted to operatively grip and rotate a tubular; a controller adapted to receive and process data indicative of a rotation, torque, and a minimum time value associated with a make-up or a break-out of the tubular and the tubular string, wherein the controller compares the rotation, torque, and minimum time values to acceptable predetermined values to determine and control when the make-up or the break-out is complete and wherein the controller is adapted to stop the make-up or break-out process when the minimum time value is exceeded and at least one of the rotation and torque values at least substantially match the corresponding predetermined values; and a user interface adapted to convey the received data, the predetermined values, or both, of the tubular make-up or break-out to an operator.
