Abstract: A system for performing operations on a work center disposed on a drill rig floor includes a robotic system having a base disposed on a track for movement thereon, a robot arm supported on the base, and one or more end effector tools selectively attachable to an end of the robot arm. A control system has a robot controller in communication with the robotic system. The robot controller is configured to command the robotic system to enter a mode for performing a selected operation, command the robot arm to engage one of the one or more end effector tools related to the selected operation from a tool storage, command the robotic system to move along the track to a position adjacent to the work center, and command the robotic system to perform the selected operation at the work center using the robot arm and the engaged end effector tool.

Abstract: A derrick structure may include a plurality of drilling rotating/hoisting/circulation (RHC) traveling block/top drive like systems that can move between and are fully functional on multiple well centers. With such a configuration, one RHC can be disconnected from the drill lines and suspended in the drilling derrick allowing two hoisting systems with separate motors to function simultaneously on a single well center, thus doubling the lifting capability on that well center. For example, one traveling block may be suspended and its associated drill line and winch coupled to another traveling block on a different well center.
