Abstract
A side saddle slingshot drilling rig includes a left and right substructure including a left and right lower box. The side saddle slingshot drilling rig includes a drill rig floor mechanically and pivotably coupled to the left and right lower boxes such that it is pivotably movable from a lowered position to a raised position. The drill rig floor includes a V-door. The V-door is positioned on the V-door side of the drill rig floor. The V-door side of the drill rig floor is oriented to face the right substructure. A mast coupled to the drill rig floor may include an open side, defining a mast V-door side. The mast V-door side may be oriented to face the right substructure. The mast may pivot into its raised position or may be a bootstrap mast.
Claims23
A drilling rig comprising:
- a right substructure and a left substructure, the substructures positioned generally parallel and spaced apart from each other;
- the right substructure including a right lower box and a first strut, the first strut pivotably coupled to a drill rig floor and pivotably coupled to the right lower box, the drill rig floor including a V-door, the side of the drill rig floor including the V-door defining the V-door side of the drill rig floor, the V-door oriented to face perpendicular to the right substructure;
- the left substructure including a left lower box and a second strut, the second strut pivotably coupled to the drill rig floor and pivotably coupled to the left lower box;
- and
- a mast, the mast including an open side defining a mast V-door side, the open side oriented to face perpendicular to the right substructure, the mast pivotably coupled to the drill rig floor by one or more pivot points and one or more lower mast attachment points, the mast being pivotable in a direction parallel to the V-door side of the drill rig floor.
A method comprising:
- providing a drilling rig, the drilling rig including:
- a right substructure and a left substructure, the substructures positioned generally parallel and spaced apart from each other;
- the right substructure including a right lower box and a first strut, the first strut pivotably coupled to a drill rig floor and pivotably coupled to the right lower box, the drill rig floor including a V-door, the side of the drill rig floor including the V-door defining the V-door side of the drill rig floor, the V-door oriented to face perpendicular to the right substructure;
- the left substructure including a left lower box and a second strut, the second strut pivotably coupled to the drill rig floor and pivotably coupled to the left lower box;
- and
- providing a mast, the mast including an open side defining a mast V-door side, the open side oriented to face perpendicular to the right substructure;
- mechanically coupling the mast to the drill rig floor;
- and
- raising the mast into a raised position.
A method comprising:
- providing a drilling rig, the drilling rig including:
- a right substructure and a left substructure, the substructures positioned generally parallel and spaced apart from each other;
- the right substructure including a right lower box and a first strut, the first strut pivotably coupled to a drill rig floor and pivotably coupled to the right lower box, the drill rig floor including a V-door, the side of the drill rig floor including the V-door defining the V-door side of the drill rig floor, the V-door oriented to face perpendicular to the right substructure, wherein the drill rig floor further comprises one or more pivot points;
- the left substructure including a left lower box and a second strut, the second strut pivotably coupled to the drill rig floor and pivotably coupled to the left lower box;
- and
- providing a mast, the mast including an open side defining a mast V-door side, the open side oriented to face perpendicular to the right substructure;
- mechanically coupling the mast to the drill rig floor by mechanically coupling the mast to the one or more pivot points;
- and
- raising the mast into a raised position.
