Abstract
A rig system includes a first base box and a second base box extending parallel to and offset from the first base box, such that an open space is defined therebetween. A rig floor is connected to the first and second base boxes and spans the open space. A mast is coupled to the rig floor. A rig-raising system is configured to raise the rig floor vertically above the ground. A combined local equipment room (LER) and drilling control room (DCR) skid is connected to the rig floor and configured to be raised with the rig floor. A reel skid is positioned at least partially vertically below the LER/DCR skid. A setback structure extends between the first and second base boxes and blocks the open space on at least one end.
