Patent attributes
Apparatus and methods include an x-direction support structure extending in the same direction as a line extending between a well center and a V-door on a drilling rig and include a y-direction support structure moveable along the x-direction support structure. The y-direction support structure extends on a drilling rig in a direction transverse to the line extending between the well center and the V-door on the drilling rig. A racker device is carried by the y-direction support structure and is configured to connect to and carry a tubular stand used in a well drilling process, the racker device being moveable along the y-direction support structure from a position inline with the line extending between the well center and the V-door on the drilling rig to a position offline from the line to provide space for additional drilling processes along the line extending between the well center and the V-door on the drilling rig.
