METHOD FOR PLACING AND REMOVING PIPE FROM A FINGER RACK

National Oilwell Varco No...

20. A system for monitoring the health of a multiplicity of latches in a finger board of a drilling rig, the system comprising:a drilling rig having a pipe handling apparatus and at least one finger board having at least two fingers defining a slot and a multiplicity of latches arranged therebetween defining a space for a pipe, each latch of the multiplicity of latches selectively movable between an open position and a closed position and a latch controller for controlling said latches between the open position and the closed position; and
a camera having a plurality of latches of said multiplicity of latches in a field of view, wherein said camera is adapted to capture an image of said plurality of latches and send said image to a master control computer that is adapted to define a sub-image of an area about one latch, said area being sufficient to cover the one latch in an open position and a closed position, said master control computer being further adapted to analyse said image for details indicative of one of the plurality of latches being in an open position or a closed position, to conclude the one latch is in an open position or a closed position, and to receive a control information in a data packet from the latch controller, the control information data packet comprising information as whether said one latch has been controlled to be in an open position or a closed position, the master control computer being further adapted and to perform a comparison of the said control information with the conclusion obtained from the image captured by the at least one camera and assessing the health of the one latch based on said comparison.

HYDRAULIC MULTI-DISPLACEMENT HOISTING CYLINDER SYSTEM

Ensign Drilling Inc., Ca...

1. An assembly for hoisting and lowering a drill string of a drilling rig, the assembly comprising:a) a multiple displacement hydraulic cylinder having a blind end, a rod end, and a hollow single piston rod with a piston configured for slidable extension and retraction movement within the interior space of the cylinder, wherein the interior space is defined by three chambers, each chamber having a port allowing switchable flow of hydraulic fluid into and out from the cylinder; and
b) a pumping and switching system with hydraulic fluid connections to each port of the cylinder, the system configured to pump hydraulic fluid via a primary pump and to switch the direction of hydraulic fluid flow through each of the ports of the three chambers, thereby providing the assembly with a plurality of hydraulic fluid flow path combinations including five hoisting combinations and three lowering combinations, wherein each combination of the five hoisting combinations and three lowering combinations provides a different speed-to-force ratio for extending or retracting the piston rod, thereby hoisting or lowering the drill string;
wherein a central tube is fixed to a blind end wall of the cylinder within the interior of the hollow piston rod, and wherein the three chambers of the cylinder are:
i) a blind end chamber with boundaries defined by a portion of the blind end wall of the cylinder; a blind end face of the piston; an interior sidewall of the cylinder and an outer diameter sidewall of the central tube;
ii) a rod end chamber with boundaries defined by a rod end side of the piston; an interior sidewall of the cylinder; an outer sidewall of the central tube, and a rod end wall of the cylinder; and
iii) a central tube chamber with boundaries defined by a portion of the blind end wall of the cylinder and the sidewall of the central tube;
wherein the port of the blind end chamber is in the sidewall of the cylinder adjacent the blind end, the port of the rod end chamber is in the sidewall of the cylinder adjacent the rod end, and the port of the central tube chamber is in the blind end wall of the cylinder;
wherein the pumping and switching system comprises a transmission manifold with switchable hydraulic fluid connections to the port of the blind end chamber, the port of the rod end chamber and the port of the central tube chamber; and
wherein the pumping and switching system comprises a secondary pump operably connected to the port of the central tube chamber for providing a secondary source of hydraulic fluid to the central tube chamber to prevent formation of a vacuum when the piston rod is extending in hydraulic fluid flow path combinations which do not include pumping of primary hydraulic fluid from the primary pump into the central tube chamber.

DEADLINE COMPENSATOR

Nabors Drilling Technolog...

1. A deadline compensator, comprising:a compensator assembly configured to engage a deadline between a crown block and a supply reel, wherein the compensator assembly is configured to transition between a first position and a second position;
at least one compensator sheave of the compensator assembly, wherein the compensator sheave is configured to engage the deadline;
at least one actuator of the compensator assembly, wherein the actuator is configured to apply a force to the deadline via the at least one compensator sheave to displace the deadline while the compensator assembly is in the first position and configured to retract into the second position in response to a second load condition on the deadline; and
a sensor engaged to the deadline configured to detect a tension force of the deadline, wherein the sensor communicates a first signal to a controller, and the controller communicates a second signal to the compensator assembly to transition the compensator assembly between the first position and the second position in response to the first signal.
