A tubular handling system for conducting subterranean operations is disclosed and can include a first tubular handling system and a second tubular handling system. The first tubular handling system can include a bridge disposed within a tubular storage area, an arm pivotally coupled to the bridge, and a gripper coupled to the arm and adapted to engage with a tubular in the tubular storage area. The second tubular handling system can include a support structure, a first tubular handler coupled to the support structure, and a second tubular handler coupled to the support structure and distinct from the first tubular handling system.

A system for performing a subterranean operation that can include a plurality of tools, and a gripper conveying means configured to connect with any one of the plurality of tools and perform a first operation on a rig. The system can also include tools with an encapsulated chamber having electronic components contained therein with the tools in compliance with an explosion-exposed (EX) certification.

A differential iron roughneck for making or breaking a pipe connection includes: at least one first gripping cylinder for delivering torque to a first pipe; at least one second gripping cylinder for delivering and receiving torque to and from a second pipe; and a differential gearbox including: a primary shaft delivering torque to the at least one first gripping cylinder; and a secondary shaft receiving torque from the at least one second gripping cylinder, where the primary shaft and the secondary shaft rotate at different speeds.

A system for use in a mineral extraction system includes a spinner assembly having a motor configured to drive rotation of a roller shaft. The spinner assembly also includes a roller non-rotatably coupled to the roller shaft and configured to contact a first tubular structure, and rotation of the roller is configured to cause rotation of the first tubular structure until the first tubular structure is spun into a second tubular structure. The spinner assembly further includes a detection wheel coupled to the roller shaft and configured to contact the first tubular structure, and the detection wheel is configured to rotate with the first tubular structure and to rotate independently of the roller. The spinner assembly further includes a sensor configured to detect rotation of the detection wheel.

A latch assembly having a first portion movably coupled with a second portion. The first portion has a roller housing, a latch panel, and handle, and the second portion has a respective roller housing, a respective latch panel, and a respective handle. In a closed position, the latch panel engages with the respective roller housing, and the respective latch panel engages with the roller housing.

A device for handling a tubular member includes a gripping assembly configured to grip the tubular member. The gripping assembly includes a first arm and a second arm, which are configured to pivot between an open position and a closed position. The device also includes a first plurality of rollers coupled to the first arm and a second plurality of rollers coupled to the second arm. The first plurality of rollers and the second plurality of rollers are configured to grip the tubular member at different locations around a circumference of the tubular member when the first arm and the second arm are in the closed position, and the first plurality of rollers and the second plurality of rollers are configured to rotate the tubular member while the tubular member is being gripped by the gripping assembly.

A system for connecting together tubulars includes a first torque-applying device, a second torque-applying device that is offset from the first torque applying device in a first horizontal direction by a first length, a loading assembly configured to convey a first tubular into axial alignment with the first and second torque-applying devices, the first tubular having an axial length that is smaller than the first length, and a tubular spinner configured to spin a second tubular into connection with the first tubular. The first torque-applying device is configured to engage the first tubular, and the second torque-applying device is configured to engage the second tubular so as to apply torque to a connection between the first tubular and the second tubular.

A frame stiffener for a power tong frame comprises a body having a top surface securable to a top plate of the frame, a bottom surface securable to the bottom plate of the frame, an outer side and an interior side having a plurality of recesses, each recess formed to conform to an angular portion of an adjacent dumbbell roller secured within the frame along with a plurality of other dumbbell rollers to rollably surround, engage and stabilize a ring gear rotatably disposed within the frame.

A power tong assembly has a transmission box having a plurality of speeds. A gear train completely encircles a rotary gear by including idler gears, fluid lines and actuating mechanisms within a tong door, which itself can be remotely operated. Cam roller assemblies can be inversely mounted into cage plates and a support race can be mounted into an opening, thereby eliminating the need to cut a groove in a rotary gear. Filler blocks can be inserted adjacent to gears to catch and redirect slung grease from gears back to said gears, while dampening noise and reducing the misuse of grease, thereby increasing effectiveness of lubrication. A make and break actuator assembly can be housed on the power tong body such that it is completely covered from external damage except when momentarily activated. A symmetric rotary gear, rotary gear inserts, cam shoe inserts and over-travel cam stops are provided.
