Abstract: An extendable, service line positioning system is provided for the deployment, retraction, and transportation of service lines that provide necessary resources (e.g., electrical, pneumatic, hydraulic, and communication resources) to a drilling rig. The positioning system comprises a plurality of connected panels supportable of a service line coupled to a vertical post on a skid. The panels are movable between a retracted position above the skid or a deployed position beyond the skid. The positioning system thus advantageously enables a drilling rig to move short distances for pad drilling operations without having the need to move resource-providing equipment coupled to supply lines.

Abstract: A system has a pipe handling apparatus with an arm moving between a first position and a second position, a derrick having a window through which the pipe handling system delivers a pipe to a well head, and a header mounted in the window of the derrick. The header receives the arm of the pipe handling system when the arm is in the second position. An outside surface of the header suitably fits within the window of the derrick. An inside surface of the derrick suitably receives the arm. The inside surface resists an upward motion and a sideways motion of the arm. The header has a body that has a head and legs.

Abstract: A pipe handling apparatus has a base, a main rotating structural member pivotally connected to the base, a pipe handler connected to the main rotating structural member for moving a pipe from a generally horizontal orientation to a vertical orientation, and a jack connected to the pipe handler. The jack exerts a downward force in generally parallel relation to the pipe when the pipe is in the vertical orientation. The pipe handler has a gripping structure for gripping an outer surface of the pipe. The gripping structure has a stab frame. The jack is affixed to the stab frame. The jack has a piston-and-cylinder assembly positioned relative to the stab frame, and a hydraulic actuator connected to the piston-and-cylinder assembly. The hydraulic actuator is suitable for passing hydraulic fluid to the piston-and-cylinder assembly so as to move the piston-and-cylinder assembly from a retracted position to an extended position.

Abstract: A blowout preventer handling apparatus including a frame structure, a carriage slidably supported on the frame structure, a raising frame pivotally supported on the carriage, and a positioner mechanism cooperatively connected to the raising frame for receiving the blowout preventer therein and for moving the blowout preventer upwardly-and-downwardly, rotationally, and side-to-side. A tray is slidably supported on the carriage so as to be movable between a first position away from the positioning mechanism to a position directly below the positioning mechanism. An outrigger assembly is selectively movable outwardly of an end of the frame structure.
