The present disclosure relates to systems and methods for automated drill pipe handling operations, such as trip in, trip out, and stand building operations. A pipe handling system of the present disclosure may include a lifting system for handling a load of a pipe stand, a pipe handling robot configured for engaging with the pipe stand and manipulating a position of the pipe stand, and a feedback device configured to provide information about a condition of the pipe stand, the lifting system, or the pipe handling robot. In some embodiments, the pipe handling robot may be a first robot configured for engaging with and manipulating a first end of the pipe stand, and the system may include a second pipe handling robot configured for engaging with and manipulating a second end of the pipe stand.

Devices, systems, and methods for robotic pipe handling

Systems and methods for clearing a top drive from an operational area of the mast such that operations may be performed along the rail without interference from the top drive. Systems and methods of the present disclosure provide for arranging the top drive in a parked configuration outside of, or generally behind, the mast. A guide rail may be arranged within an operational area of a mast and may have a pair of interchangeable rail sections, each of which may be configured for arrangement in either an operating configuration, where the rail section may be positioned within the operational area of the mast to form part of the rail, or a parked configuration, where the rail section may be positioned outside of the operational area. Each interchangeable rail section may be pivotable about an axis and may be arranged on a pivotable gate of the mast.

Devices, systems, and methods for top drive clearing

A mast erection system includes a first mast erection apparatus that is adapted to pivotably raise a drilling rig mast of a drilling rig assembly to an intermediate raised position wherein the drilling rig mast is oriented at a first acute angle relative to a horizontal plane, and a second mast erection apparatus that is adapted to further pivotably raise the drilling rig mast from the intermediate raised position at the first acute angle to a fully raised position wherein the drilling rig mast is oriented at a second angle relative to the horizontal plane that is greater than the first acute angle.

Systems and methods for raising drilling rig assemblies

A center drill floor assembly of a drilling rig structure includes a center floor structure and a drilling rig mast section that is at least partially nested within the center floor structure, wherein the center drill floor assembly is adapted to be transported to a drilling site as a single modular assembly and removably attached as a single modular assembly to a drilling rig substructure during assembly of the drilling rig structure.

Shipping arrangement and assembly procedure for drilling rig structures

Disclosed herein is a bi-directionally raisable drilling rig mast system that includes a drilling rig mast having a bi-directional mast erection connection, a first erection connection positioned proximate a first side of a rig substructure, and a second erection connection positioned proximate a second side of the rig substructure, the second side being at an opposite side of the rig substructure from the first side. The system further includes at least one mast erection apparatus having an upper end that is adapted to be pivotably attached to the bi-directional mast erection connection and a lower end that is adapted to be pivotably attached to the first erection connection for erecting the drilling rig mast from the first side of the substructure, the lower end being further adapted to be pivotably attached to the second erection connection for erecting the drilling rig mast from the second side of the substructure.

Bi-directionally raisable drilling rig mast

A system for erecting a drilling rig mast includes a substructure having an open area that is defined therein by two laterally spaced-apart substructure sides and a first mast section that is adapted to be positioned at least partially within the open area of the substructure after the first mast section has been removably connected to the substructure. The system further includes, among other things, a second mast section that is adapted to be removably connected to the first mast section the said first mast section has been removably connected to the substructure, and a mast connection apparatus that is adapted to removably connect the second mast section to the first mast section when an upper end of the first mast section is raised relative to a lower end of the second mast section.

Drilling rig masts and methods of assembly and erection

A substructure of a drilling rig is positioned above a first wellbore at a first wellbore location, a drilling rig mast is pivotably attached to the substructure and raised from a first mast position wherein an upper end of the drilling rig mast is oriented in a first direction toward a first side of the substructure to a first raised drilling position, after which a first drilling operation is performed on the first wellbore. The substructure is moved to a second wellbore location and positioned above a second wellbore, the drilling rig mast is pivotably attached to the substructure and raised from a second mast position wherein an upper end of the drilling rig mast is oriented in a second direction toward a second side of the substructure to a second raised drilling position, after which a second drilling operation is performed on the second wellbore.

Systems and methods for rig assembly and for erecting a mast of a rig and such systems with roller apparatus to facilitate movement of a mast section from a mover. In a first embodiment, the method includes erecting a rig mast section on a substructure, the substructure including a first substructure box spaced-apart from a second substructure box, the first substructure box comprising a first upper box above a first lower box and the second substructure box comprising a second upper box above a second lower box.

Drilling rig mast lift systems and methods

Disclosed herein is a raisable substructure of a drilling rig that includes first and second substructure boxes. The first and second substructure boxes of the raisable substructure each include, among other things an upper box and a lower box, wherein each of the upper boxes is adapted to be raised above a respective lower box. The disclosed raisable substructure also includes a movable center floor section that is adapted to be supported by the upper boxes of the first and second substructure boxes, wherein the movable center floor section is further adapted to be slidably moved between the upper boxes during assembly of the drilling rig.

Substructure of a mobile drilling rig with a movable center floor section

Generally, the subject matter disclosed herein is directed to, among other things, systems and methods for making up pivotably pinned structural connections that may be used for erecting drilling rig masts. One illustrative system includes a drilling rig mast having at least one support leg, a drilling rig mast support having at least one mast support shoe, and a pinned connection between the at least one support leg and the at least one mast support shoe. Additionally, the pinned connection of the disclosed system includes a pin, an oversized hole having at least a first hole portion, and a removable plug that is adapted to be inserted into the oversized hole, wherein the removable plug has at least a first plug surface portion, and wherein the first hole portion and the first plug surface portion define at least part of a pin hole that is adapted to receive the pin.
