  • Publication number: 20090294129
    Abstract: A method to interchangeably connect a plurality of Lower Marine Riser Packages with a lower BOP stack includes engaging a Lower Marine Riser Package connector of the Lower Marine Riser Package, with a Lower Stack mandrel connector of a Lower Stack, thereby aligning the Lower Marine Riser Package and the Lower Stack axially about a vertical axis, engaging at least one ring alignment pin of the Lower Marine Riser Package with at least one alignment plate of the Lower Stack, thereby rotationally aligning the Lower Marine Riser Package and the Lower Stack within a specified angle about the vertical axis, and engaging feed-thru connections between the Lower Marine Riser Package and the Lower Stack.

  • Publication number: 20080196888
    Abstract: A method to determine movement of a wellhead component includes sensing a relative position of the wellhead component with a magnetostrictive sensor over a selected interval of time. The method includes sending a signal from the magnetostrictive sensor to a data acquisition device and recording the relative position of the wellhead component with the data acquisition device with respect to the selected interval of time. Further, the method includes comparing the recorded position of the wellhead component with operations data to determine if the relative position is desirable.

  • Publication number: 20080197306
    Abstract: A ram-type blowout preventer includes a pair of ram assemblies adapted for controlled lateral movement to and from a vertical bore. Each ram assembly has a hydraulic piston connected at a first end to a ram block and at a second end to a piston tail. A magnetostrictive waveguide tube extends into a bore of at least one piston tail and a permanent magnet is disposed upon the at least one piston tail. The magnetostrictive waveguide tube has a conducting wire to receive an interrogation pulse from a transducer, the interrogation pulse generates a helical return signal in response to a relative position of the permanent magnet with respect to the waveguide tube, and the transducer is configured to receive the helical return signal and output a position of the ram block corresponding to the at least one piston tail.
