Abstract

A catwalk and crane system for transporting equipment of a well system includes a substructure, a directing frame pivotally coupled to the substructure, a pipe transporter configured to transport a tubular along the directing frame, a first actuator coupled to the directing frame and configured to rotate the directing frame relative to the substructure, and a crane coupled to the directing frame, wherein the crane is extendable from a first end of the directing frame.

First claim

What is claimed is:

1. A catwalk and crane system for transporting equipment of a well system, comprising:
a substructure;
a directing frame pivotally coupled to the substructure;
a pipe transporter configured to transport a tubular along the directing frame;
a first actuator coupled to the directing frame and configured to rotate the directing frame relative to the substructure; and
a crane coupled to the directing frame, wherein the crane is extendable from a first end of the directing frame, wherein in an extended position the crane is at a higher elevation than that of the pipe transporter.

2. The catwalk and crane system of claim 1 , wherein the directing frame is rotatable, the crane is extendable, and the pipe transporter is moveable up the directing frame to deliver a tubular to and from a rig floor of the well system.

3. The catwalk and crane system of claim 1 , further comprising:
a winch coupled to a cable that is suspended from the crane;
wherein the winch is configured to extend and retract the cable, and the cable is configured to physically support a suspended load.

4. The catwalk and crane system of claim 3 , wherein, when the load is coupled with the cable, the directing frame is configured to transport the load both vertically and horizontally in response to the extension of the crane from the first end of the directing frame.

5. The catwalk and crane system of claim 4 , further comprising a second actuator coupled to the directing frame and the crane, the second actuator configured to telescopically extend and retract the crane from the first end of the directing frame.

6. The catwalk and crane system of claim 3 , wherein, when the load is coupled with the cable, the directing frame is configured to transport the load both vertically and horizontally in response to rotation of the directing frame relative to the substructure.

7. The catwalk and crane system of claim 1 , wherein the pipe transporter comprises a catwalk skate configured to receive the tubular.

8. The catwalk and crane system of claim 7 , wherein the catwalk skate comprises rollers and is displaceable between the substructure and the directing frame to transport the tubular.

9. A catwalk and crane system for transporting equipment of a well system, comprising:
a substructure;
a directing frame pivotally coupled to the substructure;
a pipe transporter configured to transport a tubular along the directing frame;
a first actuator coupled to the directing frame and configured to rotate the directing frame relative to the substructure;
a crane coupled to the directing frame and extendable from the directing frame, wherein in an extended position the crane is at a higher elevation than that of the pipe transporter; and
a winch coupled to a cable that is suspended from the crane.

10. The catwalk and crane system of claim 9 , wherein the winch is configured to extend and retract the cable, and the cable is configured to physically support a suspended load.

11. The catwalk and crane system of claim 10 , wherein, in response to actuation from the winch, the cable is configured to transport the load from a first position to a second position elevated from the first position.

12. The catwalk and crane system of claim 9 , further comprising a sheave coupled to a first end of the crane, wherein the sheave is configured to support the cable.

13. The catwalk and crane system of claim 9 , wherein the winch is coupled to the directing frame and rotatable with the directing frame relative to the substructure.

14. The catwalk and crane system of claim 9 , wherein the first actuator is coupled between the directing frame and the substructure.

15. The catwalk and crane system of claim 9 , further comprising:
a pipe support frame pivotally coupled to the substructure and to the directing frame;
wherein the actuator is coupled between the pipe support frame and the directing frame.

16. A catwalk and crane system for transporting equipment of a well system, comprising:
a substructure;
a pipe support frame pivotally coupled to the substructure;
a directing frame pivotally coupled to the pipe support frame;
a pipe transporter configured to transport a tubular member along the directing frame; and
a crane coupled to the directing frame, wherein the crane is extendable from a first end of the directing frame, wherein in an extended position the crane is at a higher elevation than that of the pipe transporter.

17. The catwalk and crane system of claim 16 , further comprising:
a winch coupled to a cable that is suspended from the crane;
wherein the winch is configured to extend and retract the cable, and the cable is configured to physically support a suspended load.

18. The catwalk and crane system of claim 16 , wherein:
the pipe support frame comprises a first support surface;
the directing frame comprises a second support surface; and
the pipe transporter comprises a ram configured to push the tubular member along the first support surface and the second support surface.

19. The catwalk and crane system of claim 18 , further comprising:
a strut coupled between the directing frame and the substructure, wherein the strut is pivotally coupled to the directing frame at a pivot joint; and
a first actuator coupled between the directing frame and the pipe support frame and configured to rotate the directing frame about the pivot joint relative to the strut.

20. The catwalk and crane system of claim 19 , wherein the first actuator is configured to actuate the catwalk and crane system between a loading position configured to receive the tubular member, and a transport position configured to transport the tubular member between the first support surface and the second support surface.
