Abstract: A system for identifying irregularities in behaviors of a non-human animal, the system comprising a processing circuitry configured to: provide a behavioral baseline including first information on regular behaviors of the non-human animal over a given period of time when no irregularities occur; obtain data on a series of consecutively identified behaviors of the non-human animal identified over a second period of time; perform an action upon the data not complying with the behavioral baseline, thereby indicating an irregularity in the non-human animal behavior.

Abstract: 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/disengaging the top drive and a stand constrained by the clasp.

An extendable actuator is connected between the dolly and the yoke to translate the top drive to/from the dolly. Torque is transferred from the top drive through the torque tube, yoke and dolly into the mast of the drill rig.

Abstract: A tubular racking system has a racking module connected to a drilling rig mast. The racking module has a frame, a fingerboard assembly, and a clasp extendable to a stand hand-off position for securing a tubular stand in position. An upper racking mechanism (upper racking mechanism) has a bridge translatably connected to the frame. An arm is rotatably and translatably connected to the bridge. A gripper is translatably connected to the arm. A setback platform module has a platform and an alleyway adjacent the platform. A lower racking mechanism (lower racking mechanism) is translatably connected to the alleyway. The lower racking mechanism is rotatably and extendable with a clasp operable to secure a tubular stand from horizontal movement. Movements of the lower racking mechanism are controlled by movements of the upper racking mechanism.

Abstract: A tubular delivery arm that travels vertically along a rail on the front of a drilling mast in generally parallel orientation to the travel of a top drive. The tubular delivery arm has a dolly vertically translatably connected to a mast of the drilling rig. An arm is rotatably and pivotally connected to the dolly at its upper end. A tubular clasp is pivotally connected to the arm at its lower end. The dolly vertically translates the front side of the mast in response to actuation of a hoist at the crown of the mast. The tubular delivery arm translates the mast in non-conflicting passage of a top drive connected to the same mast, for positioning a tubular stand over the centerline of the wellbore, a mousehole, or a stand hand-off position.

Abstract: A casing racking module is located on a set-back platform at a forward edge of a drilling rig. The casing racking module has a casing frame forming rows for casing. Paddle assemblies are mounted on the casing frame. The paddle assemblies have a shaft, an arm pivotally located on the shaft, and a bumper pivotally located on the shaft. A rotary exit spring is located between the arm and the bumper. An arm stop limits rotation of the arm relative to the bumper. A rotary return spring is located between the bumper and the casing frame. A bumper stop aligns the bumper with the casing frame. An extendable gate opens from the end of each row.
