Equipment Used - Alternative lift & roll system
This is an alternative lift & roll system supplied by Hilman Rollers for Oil Rig 102.
The cantilever beams are supported by six rollers — 1,250 tons each. Each roller is supported by six hydraulic cylinders nested in a sub-frame. The hydraulics ensure that each roller is under full contact during the skidding mode. When retracted, the rig does not contact the rollers. No more freeze-ups! No more beam tear-ups! No more huge pushing cylinders!
