  • Patent number: 8479825
    Abstract: Method, crane system and crane for moving a component of a device. The crane includes a supporting mechanism configured to be fixedly attached to the device, an arm mechanism connected to the supporting mechanism and configured to move in a horizontal plane, a sliding mechanism connected to the arm mechanism and configured to move substantially perpendicular to the horizontal plane, and a grabbing mechanism configured to be removably attached to the sliding mechanism and configured to grab the component of the device.
    Type: Grant
    Filed: September 3, 2009
    Date of Patent: July 9, 2013
    Assignee: Hydril USA Manufacturing LLC
    Inventors: Leonard Childers, John Millican
  • Publication number: 20130153204
    Abstract: A shear ram assembly apparatus for providing the capability to shear larger diameter well casings and internal components during ram-type blowout preventer operation while requiring less force to perform the cutting. Components of the shear ram assembly apparatus, include but not limited to a plurality of hardened cutting blades that are coated with a compound that increases the hardness and reduces the coefficient of friction of the cutting blades. In this regard, a smaller force is required to perform the cutting and the cutting blades receive less wear per cut and provide greater assurance that each cut of this failsafe apparatus is successful.

  • Patent number: 8166993
    Abstract: Blowout preventer (BOP) and method for sealing a well. The BOP includes a body having first and second conduits, the first conduit being substantially perpendicular on the second conduit; a piston extending through the first conduit and being configured to reciprocate inside the first conduit, the piston having a body portion, a neck portion and a head portion in this order; a ram block disposed on the piston and configured to move with the piston inside the first conduit for closing the second conduit; and a shim configured to fill a gap between a back region of the ram block and the body portion of the piston.
