Abstract
A pipe handling system that can include a base skid, a ramp rotationally attached to the base skid, and support equipment (e.g., a drag chain pan, or equipment skid) coupled to the ramp, wherein rotation of the ramp from a first deployed position to a first stowed position lifts the support equipment from a second deployed position to a second stowed position. A method can include rotating the ramp relative to the base skid from a first deployed position to a first stowed position, and simultaneously lifting support equipment relative to the base skid from a second deployed position to a second stowed position in response to rotating the ramp.
Claims20
A system for conducting subterranean operations comprising:
- a pipe handling system configured to transport tubulars between a horizontal storage location and a rig floor of a rig, the pipe handling system comprising:
- a base skid;
- a ramp rotationally attached to the base skid at a first pivot point;
- and
- support equipment rotationally attached to the base skid at a second pivot point, wherein the first pivot point is spaced away from the second pivot point, wherein the support equipment is positioned proximate the rotational attachment of the ramp to the base skid, and wherein rotation of the ramp from a first deployed position to a first stowed position lifts the support equipment from a second deployed position to a second stowed position.
A system for conducting subterranean operations comprising:
- a pipe handling system configured to transport tubulars between a horizontal storage location and a rig floor of a rig, the pipe handling system comprising:
- a base skid;
- a ramp rotationally attached to the base skid;
- and
- support equipment positioned proximate the rotational attachment of the ramp to the base skid, wherein rotation of the ramp from a first deployed position to a first stowed position lifts the support equipment from a second deployed position to a second stowed position, and wherein the support equipment comprises a drag chain pan, and wherein the drag chain pan is rotationally attached to the base skid at pivot points and the drag chain pan is coupled to the ramp.
A method for conducting subterranean operations comprising:
- moving a pipe handling system, the pipe handling system comprising a ramp rotationally attached to a base skid, and a drag chain pan rotationally attached to the base skid;
- rotating the ramp relative to the base skid from a first deployed position to a first stowed position;
- and
- simultaneously rotating the drag chain pan relative to the base skid from a second deployed position to a second stowed position in response to rotating the ramp from the first deployed position to the first stowed position.
