A system can include a top drive with a quill with a pivot joint, with an upper portion pivotably coupled to a lower portion via a pivot, coupled between the quill and a running tool, wherein rotation of the lower portion relative to the upper portion pivots the running tool about the pivot. A method for running a tubular string by moving a tubular along a catwalk, coupling a pivot joint between a running tool and a quill, and pivoting the running tool about the pivot by pivoting the lower portion relative to the upper portion.

Pivot joint with a rotatable lower portion

Top drive movement measurement system having a sensor module configured to be disposed about and couple to a component of a top drive system, a first plurality of sensors of the sensor module, wherein the first plurality of sensors is configured to detect lateral movement of the component of the top drive system, and a second plurality of sensors of the sensor module, wherein the second plurality of sensors is configured to detect one or more compression or tension forces in the component of the top drive system.

Top drive movement measurements system and method

Present embodiments are directed to a tubular stress measurement system including a first sensor configured to detect a parameter indicative of an axial or circumferential position of the plurality of grapples and a calculation system configured to calculate an internal stress on the tubular based on the parameter.
