1. A substructure for a drilling apparatus, comprising:
- a base structure;
a floor structure coupled to the base structure by a plurality of support members; and
a power train disposed on the floor structure, the power train providing motive force to the support members for moving the floor structure relative to the base structure in a single first linear direction and maintaining the base structure and floor structure in a substantially parallel relationship, wherein the power train is positioned substantially normal to the first linear direction.

Abstract
A method and apparatus for a moving a floor structure relative to a base structure is provided. The apparatus includes a base structure having an opening for a well head, a floor structure coupled to the base structure by a plurality of support members, and a drive mechanism disposed on the floor structure, the drive mechanism providing motive force to the support members for moving the floor structure relative to the base structure in a single first direction.
