A system comprising a drilling rig having a rig floor, a derrick, a master control computer system and at least one camera, the at least one camera capturing a master image of at least a portion of the rig floor, sending the master image to the master control computer, the master control computer system mapping said master image into a model to facilitate control of items on said drilling rig.

Drilling rig

A system for placing and removing pipe from a finger rack of a drilling rig, the system comprising a pipe handling apparatus () and a finger rack () having at least one finger board () having at least two fingers (to) defining a slot (to) 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, the system further comprising at least one camera () having said at least one latch () of said multiplicity of latches in a field of view, capturing an image of said latch and sending said image to a master control computer ('), said master computer control computer (&#x2032;) programmed with a set of instructions to analyze said image for details indicative of the latch () being in an open position or closed position, concluding the latch () to be in an open position or closed position and allowing or disallowing a pipe handling apparatus to place or remove a pipe in the finger rack () based on said conclusion.

Method for placing and removing pipe from a finger rack

A die holder device includes a die holder that has an axial centre line and is adapted to receive a clamp die. The die holder is included in a clamp arm or slide block. The die holder is restricted from axial movement by at least a first complete or partial conical surface and possibly by a second complete or partial conical surface that directly or indirectly bears against the clamp arm or the slide block.

Die holder device and method for utilizing the same

A clamping system for making and breaking threaded connections between a first tubular and a second tubular comprises a clamp assembly. The clamp assembly includes a first cam gear, a first plurality of clamp members disposed within the first cam gear, and a torque gear. Each clamp member is pivotally coupled to the torque gear. Each clamp member is configured to pivot between a withdraw position radially spaced apart from the first tubular and a gripping position engaging the first tubular. In addition, the clamping system comprises a clamp actuator. The clamp actuator includes a mounting shaft, a first clamp drive gear rotatably coupled to the mounting shaft, and a torque drive gear rotatably coupled to the mounting shaft. The first clamp drive gear is configured to rotate the first cam gear and the torque drive gear is configured to rotate the torque gear.
