Abstract

Claims (17)

1. A tubular handling system for conducting a subterranean operation, the system comprising:

a bridge disposed in a horizontal position proximate a drill floor, the bridge comprising first and second bridge rails with a space between;

an arm coupled to the first and second bridge rails, the arm configured to manipulate a tubular through the space between the first and second bridge rails, and to move along the bridge; and

a tubular lift system that raises or lowers the tubular in a horizontal orientation between a horizontal storage area and an intermediate storage location, the arm being configured to collect the tubular from the intermediate storage location and present the tubular to a well center on the drill floor or to a pipe handler, or to collect the tubular from the well center or the pipe handler and deposit the tubular in the intermediate storage location.

2. The system of claim 1 , wherein the tubular lift system comprises left and right vertically oriented conveyances, and wherein each of the left and right vertically oriented conveyances comprise multiple actuators that cooperate together to raise or lower the tubular in the horizontal orientation between the horizontal storage area and the intermediate storage.

3. The system of claim 2 , wherein the multiple actuators of the left and right vertically oriented conveyances simultaneously raise or lower one or more tubulars.

4. The system of claim 1 , wherein the tubular lift system comprises a front lift system and a rear lift system, wherein the front lift system is configured to vertically transport multiple tubulars in the horizontal orientation between a first portion of the horizontal storage area and an intermediate storage location, and wherein the rear lift system is configured to transport multiple tubulars in the horizontal orientation between a second portion of the horizontal storage area and the intermediate storage location.

5. The system of claim 4 , wherein the front lift system delivers the tubular into a longitudinal groove of the intermediate storage location from a first side of the intermediate storage location, and wherein the rear lift system delivers the tubular into the longitudinal groove from a second side of the intermediate storage location.

6. The system of claim 5 , wherein the first side and the second side are opposite sides of the intermediate storage location.

7. The system of claim 1 , wherein the intermediate storage location comprises:

a longitudinal groove that receives the tubular; and

one or more sensors that measure a parameter of the tubular that is present in the longitudinal groove.

8. The system of claim 7 , wherein the parameter is selected from a group consisting of weight, length, diameter, tubular damage, or combinations thereof.

9. The system of claim 1 , wherein the pipe handler comprises a top drive, an elevator, or a vertical pipe handler.

10. The system of claim 1 , further comprising a doping device, wherein the arm is configured to manipulate the tubular to extend an end of the tubular into the doping device.

11. The system of claim 10 , wherein the doping device applies dope to the end of the tubular when the end is in the doping device.

12. The system of claim 10 , wherein the arm comprises multiple grippers that are configured to engage the tubular and allow the arm to manipulate the tubular when the multiple grippers are engaged with the tubular.
