Abstract: An apparatus for centering a first tubular with respect to a second tubular at a wellhead in which the apparatus has a frame, a gripping member extending outwardly of the frame and suitable for gripping the first tubular, and a guide member connected to the frame and extending outwardly therefrom. The guide member is positioned below the gripping member. The guide member has a slot therein suitable for receiving a portion of the second tubular therein. The slot of the guide member has a center vertically aligned with a center of the gripping member. The guide member is pivotally connected to the frame.

Abstract: An apparatus for connecting or disconnecting a threaded connection of a first tubular member and a second tubular member at a wellhead has a frame movable between a first position adjacent the wellhead and a second position away from the wellhead, a first gripping member connected to the frame and extending outwardly therefrom so as to apply a torque to the first tubular, and a second gripping member movably connected to the frame so as to be movable between a first position away from the wellhead and a second position at the wellhead. The second gripping member is suitable for applying an opposing torque to the second tubular.

Abstract: A sensor apparatus (104) includes a plural different spatial direction axis of sensitivity positioned sensor package containing sensor module (305) supported by a planar surface (345) within a cavity (340) of a housing (205) coupled to a first end cap (210) by a PC-board connection (355). Housing (205) is further coupled to first end cap (210) by a first coupling member (315) and a second coupling member (320) and is also coupled to an opposite second end cap (215) by a third coupling member (320) and a fourth coupling member (325). Interface sealing members (330a, 330b, 330c, 330d) seal between housing (205) and first end cap (210). Interface sealing members (335a, 335b, 335c, 335d) seal between housing (205) and second end cap (215).

Abstract: A system for remotely controlling, acquiring and monitoring the acquisition of seismic data. The system includes remote equipment for collecting seismic data and for transmitting and receiving communication signals to and from a remote location. The system also includes local equipment for transmitting and receiving communication signals to and from the remote location. In this manner, the collection of seismic data at remote locations can be controlled and monitored locally on a real-time basis.

Abstract: A remotely-operated unmanned vehicle attached to the hull of a marine vessel by electromagnets surveys the hull for damage. The vehicle attached to the hull is electronically controlled from a remote location. An imaging system on the vehicle provides an operator with images of the vessel's hull and the surrounding environment. Once damage has been found and assessed, the vehicle applies a patch over the damaged opening in the hull to prevent cargo outflow and water inflow. The patch, which resists puncturing and tearing, is constructed from one or more sheets of flexible material having dimensions appropriate to cover most openings.
