Abstract
An improved system and method for bracing, transporting, assembling, and disassembly of drilling equipment at oil and gas land-based well sites. The system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with telescoping tension link(s), linking pins, and vertical hydraulic cylinders. These linking pins are set after raising the substructure and secure the telescoping tension link, support arms, and support bracing in place to maintain the integrity of the substructure. Alternatively the system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with screw jacks and a means of stabilization during substructure raising. The substructure bracing reduces the overall length, reduces the upper and lower box spans, and balances the raising loads, subsequently lowering the transport weight of the side box such that a commercial walking system may be integrated into the side box and remain there during transport while maximizing the operating drill floor height while minimizing the transport height.
