A tubular handling system for conducting subterranean operations is disclosed and can include a bridge disposed within a tubular storage area and coupled to a guide rail. The bridge is configured to translate from a first bridge position to a second bridge position along the guide rail and over the tubular storage area. The tubular handling system can further include an arm coupled to the bridge and a gripper coupled to the arm. The gripper can be adapted to engage a first tubular.

A drill pipe guide system having a support structure configured to be positioned on a rig floor or drillship floor, an articulating arm coupled to the support structure, wherein the articulating arm is coupled to the support structure, wherein the articulating arm is configured to pivot relative to the support structure, and a clamp coupled to the articulating arm, wherein the clamp is configured to encircle a drill string and limit radial movement of the drill string as the drill string is lowered beneath the rig floor or drillship floor.

Drilling installation comprising a cantilever with a drilling floor for performing drilling operations; further comprising an independent operations handling system arranged for handling equipment underneath the drilling floor independent of the drilling operations on the drilling floor, wherein the independent operations handling system comprises a handling element for cooperation with the equipment to be handled, wherein the handling element is extendible underneath the cantilever.

A sucker rod tong assembly for fastening together sucker rods to a rod coupling, where the assembly can include a two-stage mechanical drive mechanism. The first stage can connect an upper sucker rod to a lower sucker rod via a rod coupling. The first stage can be limited in mechanical ability to tighten the connection to a pre-set shoulder torque value. The second stage can then be hydraulically and mechanically sequenced, using a linear gear drive mechanism, to rotate a main tong pinion gear that can further rotate the sucker rod connection through a fixed circumferential displacement to a mechanical stop.

A high trip rate drilling rig has first handling equipment to transport stands in/out of setback, second handling equipment to deliver stands to/from well center, and a hand-off position to set down stands for exchange between first/second equipment. Second equipment can include a top drive and a delivery arm translatable along the mast past each other, and a clasp on the arm slidable on the stand for constraint below the upper end, which can allow the top drive to engage/disengage the constrained stand above the arm. A high trip rate method transports stands in/out of setback, delivers stands to/from well center, and sets down and hands off stands at hand-off position between the setback transportation and well center delivery. The delivery can include engaging/dis-engaging the top drive and a stand constrained by the clasp.

A drill rod handler (30) for use on a drilling rig (10). In at least one embodiment, the drill rod handler (30) comprises a boom (32) having jaws (38) for releasably grasping a drill rod (14) in at least two spaced apart positions along the length of the drill rod, and a boom positioning means for positioning the boom so that the jaws may grasp a drill rod (14) from a rod storage (18) on the drilling rig or from another rod storage at a different location (16). In another embodiment, a drill rod handler comprising a boom having jaws for releasably grasping a drill rod in at least two spaced apart positions along the length of the drill rod, a boom tilt mechanism for raising or lowering an end of the boom and a drill rod when the drill rod is grasped by the jaws; and an interconnect for connection to the end of the boom for stabilising the end of the boom with respect to the a mast (20) of the drilling rig (10) when the boom (32) is in a rod presentation position.

A system, includes a movable platform slidingly coupled to one or more supports and configured to be selectively moved towards a drill floor and away from the drill floor. The system also includes a roughneck disposed on the movable platform and configured to make up or break out a threaded joint between a first tubular segment and a second tubular segment. The system additionally includes a support member disposed on the movable platform and configured to support one of the first tubular segment or the second tubular segment as the movable platform is selectively moved towards a drill floor or away from the drill floor.
