Abstract

A catwalk for transporting tubular members of a well system includes a substructure, a first transport frame pivotally coupled to the substructure at a first pivotal joint and including a first support surface configured to engage the tubular member, a second transport frame pivotally coupled to the first transport frame at a second pivotal joint and including a second support surface configured to engage the tubular member, and a strut pivotally coupled between the second transport frame and the substructure, wherein the strut is configured to transfer the weight of the tubular member from the second transport frame to the substructure when the tubular member is transported between the first support surface and the second support surface.

First claim

What is claimed is:

1. A catwalk for transporting tubular members of a well system, comprising:
a substructure;
a first transport frame pivotally coupled to the substructure at a first pivotal joint and comprising a first support surface configured to engage the tubular member;
a second transport frame pivotally coupled to the first transport frame at a second pivotal joint and comprising a second support surface configured to engage the tubular member; and
an actuator having a first end pivotally coupled to the first transport frame and a second end pivotally coupled to the second transport frame, wherein the actuator is configured to actuate the catwalk between a first position configured to receive the tubular member and a second position configured to transport the tubular member between the first support surface and the second support surface.

2. The catwalk of claim 1 , further comprising a ram configured to displace the tubular member in a linear direction between the first support surface and the second support surface.

3. The catwalk of claim 2 , wherein the ram is configured to push against an end of the tubular member to displace the tubular member between the first support surface and the second support surface.

4. The catwalk of claim 2 , wherein:
the first support surface comprises a first central groove configured to receive the tubular member;
the second support surface comprises a second central groove configured to receive the tubular member; and
the ram is configured to travel through both the first central groove and the second central groove.

5. The catwalk of claim 1 , further comprising a strut pivotally coupled between the second transport frame and the substructure, wherein the strut is configured to transfer the weight of the tubular member from the second transport frame to the substructure when the tubular member is transported between the first support surface and the second support surface.

6. The catwalk of claim 5 , wherein:
the actuator is configured to rotate the first transport frame in a first rotational direction about the first pivotal joint in response to extending the first end of the actuator from the second end of the actuator; and
the actuator is configured to rotate the second transport frame about a third pivotal joint coupling the stmt with the second transport frame in a second rotational direction opposite the first rotational direction in response to extending the first end of the actuator from the second end of the actuator.

7. The catwalk of claim 1 , wherein:
a first longitudinal axis of the first support surface is disposed at an angle relative to a second longitudinal axis of the second support surface when the catwalk is in the first position; and
the first longitudinal axis is disposed parallel with the second longitudinal axis when the catwalk is in the second position.
