An actuator assembly with integrated torque turn monitoring is described. Embodiments include a rotationally fixed outer hydraulic section and a rotationally independent inner hydraulic section which incorporates torque load sensors and rotational speed sensors directly into the inner hydraulic section. The inner hydraulic section is coupled to an outer cage by a cage ring and is axially movable relative to the inner mandrel. Upper and lower fluid chambers are disposed between the outer housing assembly and the inner mandrel. Fluid pumped through a lower pressure port into the lower chamber moves the housing assembly in a first direction, and fluid pumped through an upper pressure port into the upper fluid chamber moves the housing assembly in a second direction.

IMPROVED HYDRAULIC ACTUATOR WITH INTEGRAL TORQUE TURN MONITORING
An actuator assembly with integrated torque turn monitoring is described. Embodiments include a rotationally fixed outer hydraulic section and a rotationally independent inner hydraulic section which incorporates torque load sensors and rotational speed sensors directly into the inner hydraulic section. The inner hydraulic section is coupled to an outer cage using by a cage ring and is axially movable relative to the inner mandrel. Upper and lower fluid chambers are disposed between the outer housing assembly and the inner mandrel. Fluid pumped through a lower pressure port into the lower chamber moves the housing assembly in a first direction, and fluid pumped through an upper pressure port into the upper fluid chamber moves the housing assembly in a second direction.

An actuator assembly for operating a tubular running device includes a housing assembly coupled to the outer cage. The housing assembly is movable relative to the inner mandrel. An upper fluid chamber is disposed between the housing assembly and the inner mandrel, and a lower fluid chamber is disposed between the housing assembly and the inner mandrel. Fluid pumped through an upper pressure port into the upper chamber moves the housing assembly in a first direction thereby causing the gripping apparatus to engage the tubular, and fluid pumped through a lower pressure port into the lower fluid chamber moves the housing assembly in a second direction thereby causing the gripping apparatus to disengage the tubular.
A bi- directional fluid safety valve for preventing spillage when filling tanks, vessels, fill lines, and or hoses for transportation of fluids in pipelines or tubulars with a tubular body with an external body and an internal bore having a fluid flow path from a first end to a second end, the first and second members concentrically disposed and moveable along a longitudinal axis within the tubular body; with means such as springs to longitudinally bias the first member toward the second member and means to longitudinally bias said second member toward said first member. Also provided are embodiments for connection of the tubular body to alternative connection systems.
A method and apparatus for running tubular(s) into a well bore for use with a top drive or power swivel comprising a make-up assembly with inner and outer members, one of which has an array of ramped or inclined surface(s) while the other is an inner or outer cage with rolling support(s) with or without a central spindle and openings which may also be referred to as tubular engagement apparatus wherein relative movement of the members urges the rolling support(s) to protrude radially through the openings to engage a tubular internally or externally. Also provided is an elevator assembly with elevator links and transfer elevators to position tubular for engagement by the make-up assembly.
A method and apparatus for facilitating running or pulling tubulars from a well bore whereby the manual operations or functions normally performed by a human are undertaken by the THD and may including remote control or manipulation. The THD comprises an elevator assembly (THD) with a main body consisting of upper and lower plates, a scissor assembly and multiple sized die blocks to conform to the tubular diameter. The THD can be used as a transfer elevator to position the tubular for engagement by the make-up assembly, can be outfitted to perform as a safety clamp or restraining device and also configured as a tubular stabbing arm as required by the operation.
A method and apparatus for facilitating running or pulling tubulars from a well bore whereby the functions of a surface mounted traditional spider/ elevator are replaced by an FMS which may also be remotely controlled. The FMS comprises a main body consisting of upper and lower plates assembled in a bolted and welded configuration, a slip assembly each said slip assembly comprising a slip back, a slip, one or more die inserts, a hydraulic or pneumatic cylinder and multiple sized die blocks to conform to the tubular OCTG diameter.
A method and apparatus for running tubular into a well bore for use with a top drive or power swivel comprising a make-up assembly with inner and outer members one of which has an array of ramped surfaces while the other is a outer or outer cage with slipper-gripper blocks and apertures wherein relative movement of the members urges the slipper-gripper block to protrude radially through the apertures to engage a tubular internally or externally. Also provided is an elevator assembly with elevator links and transfer elevators to position tubular for engagement by the make-up assembly.
