Abstract
A gate assembly that can include a frame with first and second mounts to mount the gate assembly across a V-door space on a rig floor, a first gate rotationally attached to a left side of the frame, and a second gate rotationally attached to a right side of the frame, such that the first and second gates selectively permit and prevent access through the V-door space. Inner panels of the first and second gates can be configured to automatically open and close in response to a catwalk extending into the V-door space or retracting from the V-door space.
