A drilling rig may include a mast and a top drive system. The mast is aligned with a wellbore, the wellbore defining a wellbore centerline. The top drive system may include a top drive. The top drive is movable vertically relative to the mast. The top drive is movable horizontally between a position aligned with the wellbore centerline and a position out of alignment with the wellbore centerline.

A mud bucket system including a base structure and a bellows with a longitudinal internal cavity, the base structure attached to one end of the bellows and a retention ring attached to another end, where the vertical movement of the retention ring lengthens or shortens the longitudinal internal cavity, and a method of using the system that can include coupling a mud bucket to a rig floor, raising a retention ring of the mud bucket, thereby elongating a longitudinal internal cavity of the mud bucket such that a connection of a tubular string is positioned within the longitudinal internal cavity, and unthreading the connection while the connection is positioned within the longitudinal internal cavity, where a tubular is connected to the tubular string at the connection and unthreading the connection disconnects the tubular from the tubular string and expels a fluid from the tubular into the longitudinal internal cavity.

An automated drilling rig system includes a drilling rig and a catwalk system. The drilling rig includes a rig floor, a substructure, a mast, a top drive, and a pipe handling apparatus. The pipe handling apparatus includes a column coupled to the rig floor at a position offset from the well centerline. The catwalk system includes a pipe tub, a catwalk lift frame, and a catwalk assembly. The pipe tub is configured to store one or more tubular members for use with the drilling rig. The catwalk assembly includes a base and a catwalk slide. The catwalk lift frame is coupled to the base of the catwalk assembly and extends substantially vertically to the rig floor. The catwalk slide is coupled to the catwalk lift frame at a first end and pivotably coupled to the base at a second end via a leveling strut. The catwalk slide includes a skate adapted to slide along the length of the catwalk slide.

A stair tower for a drilling rig is disclosed, the stair tower including a frame, one or more stair flights and platforms positioned within and mechanically coupled to the frame, and a cable tray pivotably coupled to the frame.

A ground handling system includes a main skid. The main skid has a main skid frame that includes a main tubular handling cradle. The main skid also includes a catwalk mechanically coupled to the main skid frame. In addition, the ground handling system includes a secondary skid mechanically coupled to the main skid. The second skid includes a second skid frame that includes a second tubular handling cradle. The second skid also includes a second catwalk mechanically coupled to the secondary skid frame. Tubulars may be transferred from the second tubular handling cradle to the main tubular handling cradle. The main skid further may include a pipe treatment carriage slidably coupled to the main skid frame and supporting one or more of a cleaning canister, doping canister, roller clamp, or tire clamp.
