1. A stair tower for a drilling rig having a drill rig floor, the stair tower comprising:
- a frame, the frame adapted to be transported separately from the drilling rig, the frame adapted to be coupled to the drilling rig;
one or more stair flights and platforms positioned within and mechanically coupled to the frame; and
a cable tray pivotably coupled to the frame, the cable tray pivotable between a vertical retracted position and a horizontal extended position, the cable tray aligned with the drill rig floor when in the extended position, the cable tray configured to be directly coupled to the drill rig floor at a distal end of the cable tray when in the extended position.

20. A method comprising:
-
providing a drilling rig, the drilling rig including a drill rig floor; transporting a stair tower to the drilling rig in a horizontal position, 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, the cable tray having one or more of electrical cables or utility piping running on or through the cable tray from the frame to a distal end of the cable tray; raising the stair tower from the horizontal position to a vertical position; mechanically coupling the stair tower to the drilling rig; pivoting the cable tray from a vertical position to a raised, horizontal position, the cable tray substantially aligned with the drill rig floor when in the raised position; coupling the distal end of the cable tray directly to the drill rig floor; and mechanically coupling the one or more of electrical cables or utility piping to one or more of corresponding electrical cables or utility piping of the drilling rig on the drill rig floor. - View Dependent Claims (21)
