Automatic method for installing mobile drilling rig at a drilling site
First Claim
1. A method for installing a mobile drilling rig at a drilling site comprising the steps of:
- a. transporting the mobile drilling rig to the drilling site, wherein the mobile drilling rig comprises;
i. a mast;
ii. a driller'"'"'s side substructure comprising a first mast starting section;
a driller'"'"'s floor side box connected to the first mast starting section;
a first driller'"'"'s elevating leg;
a second driller'"'"'s elevating leg, wherein the first and second driller'"'"'s elevating legs engage the driller'"'"'s floor side box;
a driller'"'"'s subbase side box engaging the first and second driller'"'"'s elevating legs; and
a driller'"'"'s raising cylinder engaging the driller'"'"'s subbase side box;
iii. an off-driller'"'"'s side substructure comprising a second mast starting section;
an off- driller'"'"'s floor side box connected to the second mast starting section;
a first off-driller'"'"'s elevating leg;
a second off-driller'"'"'s elevating leg, wherein the first and second driller'"'"'s elevating legs engage the off driller'"'"'s floor side box;
an off-driller'"'"'s subbase side box engaging the first and second off-driller'"'"'s elevating legs; and
an off-driller'"'"'s raising cylinder engaging the off-driller'"'"'s subbase side box;
b. placing the driller'"'"'s side substructure and the off-driller'"'"'s side substructure parallel to one another at the drilling site;
c. connecting the mast to the first and second mast starting sections;
d. extending the driller'"'"'s and off-driller'"'"'s raising cylinders into a mast raising position to raise the mast into a substantially vertical orientation and locking the mast in the substantially vertical orientation;
e. retracting the raising cylinders from the mast raising position and re-extending the raising cylinders into a drill floor raising position; and
f. extending the raising cylinders to raise the driller'"'"'s floor side box and the off-driller'"'"'s floor side box into an operating elevation.

Abstract
A method for installing a mobile drilling rig at a drilling site entails transporting the mobile drilling rig to the drilling site, wherein the mobile drilling rig is made three sections: two substructures and a mast section. The substructures are placed parallel to one another at the drilling site. The mast section is connected to the mast starting sections located on each substructure. Raising cylinders on the substructures engage the mast and raise the mast into a substantially vertical orientation, wherein the mast is locked in place. The raising cylinders are retraced and then re-extended into a drillfloor raising position. The method ends by extending the raising cylinders to raise the driller'"'"'s floor side box and the off-driller'"'"'s floor side box into an operating elevation.
