Abstract: Methods and apparatus for running tubulars into and out of a wellbore. A gripping apparatus is activated with an actuator having a primary actuator and a redundant safety feature. The backup safety feature may include one or more redundant fluid operated pistons. The gripping apparatus may include an integrated safety system adapted to prevent damage to the tubulars while making and breaking out connections between the tubulars and the tubular string. The apparatus may be part of a top drive and comprise a swiver, a cementing plug launcher and/or a sensor.

Abstract: A control line running system includes a control line storage unit and a guiding system having a guiding device and a guide rail for guiding a control line from the control line storage unit toward a well center. The system may also include a control line manipulator assembly for moving the control line toward a tubular and a control line clamp for attaching the control line to the tubular.

Abstract: A method of ensuring sfte operation of a top drive, involves operating a top drive, thereby rotating a quill of the top drive, wherein the quill of the top drive is connected to a torque head or a spear. Hydraulic communication is provided between the torque head or spear and a hydraulic pump by means of a swivel. A bearing is disposed between a housing and a shaft of the swivel. The method further involves determining acceptability of operation of the bearing by monitoring a torque exerted on the swivel housing by the bearing and stopping operation of the top drive and/or notifying an operator of the top drive if the bearing operation is unacceptable.

Abstract: Embodiments of the invention relate to a gripping apparatus for supporting a tubular. The gripping apparatus (100) may include a housing (200), a slip assembly (300) disposed in the housing, and a leveling ring (400) operable to move the slip assembly in the housing. The gripping apparatus may further include a guide member (415) and a mating member (447) operable to couple the slip assembly to the leveling ring. The longitudinal movement of the leveling ring directs the mating member along the guide member to radially displace the slip assembly relative to the housing.
