Robotic pipe handling from outside a setback area
A pipe handling system for handling drill pipe on a drill rig may include a lifting system configured for handling a load of a pipe stand and a first pipe handling robot arranged at or near a drill floor of the drill rig and configured for manipulating a bottom end of the pipe stand between a setback area on the drill floor and well center. The system may also include a second pipe handling robot arranged at or near a racking board of the drill rig and configured for manipulating a top end of the pipe stand between the racking board and well center. The first pipe handling robot may have a base that is supported from a location outside a plan view envelope of the setback area of the drill floor.
1. A pipe handling system for handling drill pipe on a drill rig, the system comprising:
a lifting system configured for handling a load of a pipe stand;
a boom pivotally supported at a location outside a setback area of a drill floor and extending to a free cantilevered end, the boom configured to swing about a vertical axis and across the drill floor;
a first pipe handling robot mounted on the free cantilevered end of the boom and configured to pivot about a vertical axis relative to the boom and to articulate for manipulating a bottom end of the pipe stand between a setback area on the drill floor and well center;
a second pipe handling robot arranged at or near a racking board of the drill rig and configured for manipulating a top end of the pipe stand between the racking board and well center.
2. The pipe handling system of claim 1 , wherein the second pipe handling robot is arranged on a rail system positioned above the setback area, between first and second portions of the racking board when viewed in plan view, and generally aligned with well center.
3. The pipe handling system of claim 2 , wherein the second pipe handling robot is configured to articulate along the rail system.
4. The pipe handling system of claim 3 , wherein second pipe handling robot is suspended below the racking board.
5. The pipe handling system of claim 1 , wherein the boom is configured to swing the first pipe handling robot along an arc to allow the first pipe handling robot to place pipe stands in or retrieve pipe stands from the setback area.
6. The pipe handling system of claim 5 , wherein the arc passes across the setback area.
7. A pipe handling system for handling drill pipe on a drill rig, the system comprising:
a lifting system configured for handling a load of a pipe stand;
a pair of first pipe handling robots arranged at or near a drill floor of the drill rig and configured for manipulating a bottom end of the pipe stand between a setback area on the drill floor and well center;
a second pipe handling robot arranged at or near a racking board of the drill rig and configured for manipulating a top end of the pipe stand between the racking board and well center;
wherein, the pair of first pipe handling robots each have a base supported from a location outside a plan view envelope of the setback area of the drill floor and arranged on respective rail systems.
8. The pipe handling system of claim 7 , wherein the pair of pipe handling robots are secured to the drill floor at a location generally between the setback area and well center.
9. The pipe handling system of claim 8 , wherein the setback area includes a first portion and a second portion and each robot of the pair of pipe handling robots is associated with a respective first portion or second portion.
10. The pipe handling system of claim 9 , wherein each robot of the pair of pipe handling robots is configured to handle pipe stands near a front of the first portion or the second portion, which the respective robot is not associated with.
11. The pipe handling system of claim 8 , wherein a base of each of the pair of robots is positioned to substantially abut an outboard boundary line extending from an outboard edge of the setback area.
12. The pipe handling system of claim 7 , wherein each rail system of the respective rails systems is arranged along a respective outboard edge of the setback area and generally parallel to a line extending through well center and bisecting the setback area.
13. The pipe handling system of claim 12 , wherein the pair of pipe handling robots are configured to articulate along their respective rails systems.
14. A system of pipe handling robots on a drill rig, the system comprising:
a boom pivotally supported at a location outside a setback area of a drill floor and extending to a free cantilevered end, the boom configured to swing about a vertical axis and across the drill floor;
a first pipe handling robot mounted on the free cantilevered end of the boom and configured to pivot about a vertical axis relative to the boom and to articulate for manipulating a bottom end of the pipe stand between a setback area on the drill floor and well center,
a second pipe handling robot arranged at or near a racking board of the drill rig and configured for manipulating a top end of a pipe stand between the racking board and well center.
