Abstract:
The present disclosure, in one or more embodiments, relates to a drilling rig with a self-elevating drill floor. The drilling rig may have one or more jacking systems that may operate to raise the drill floor. The one or more jacking systems may raise the drill floor to a height sufficient to accommodate a substructure such as a substructure box. A substructure box may be placed, and the one or more jacking systems may lower the drill floor onto the substructure box. Substructure boxes may be placed beneath the drill floor, using the one or more jacking systems, until a desired drill floor height is reached. In some embodiments, the one or more jacking systems may additionally operate to move the drilling rig, for example between adjacent wells on a pad drilling site. The jacking systems may operate to move the drilling rig using walking feet or another mechanism.
