Publication number: 20140346772Abstract: A telescopic joint for a marine drilling riser has an outer barrel and an inner barrel defining a central lumen for passage of a drill pipe string. The inner barrel is received within the outer barrel, and there is a clearance fit between the barrels for sliding of the inner barrel with respect to the outer barrel while maintaining a coaxial relationship between the barrels. A tubular rolling elastomeric membrane is disposed within the outer barrel and has one end secured to an outer circumference of the inner barrel and another end secured to an inner circumference of the outer barrel for sealing drilling fluid within the central lumen. As the inner barrel slides with respect to the outer barrel, the elastomeric membrane rolls with respect to the inner barrel and the outer barrel so that wear of the seal due to abrasion is eliminated.Type: ApplicationFiled: May 12, 2014Publication date: November 27, 2014Applicant: Oil States Industries, Inc.Inventors: Danton Gutierrez-Lemini, Eric Luke

Publication number: 20140263142Abstract: For load compensation, different kinds of elastomeric load compensators are placed at various locations on the crane for increased flexibility and for shock and vibration absorption. The elastomeric load compensators employ elastomeric tension elements, elastomeric torsion elements, or elastomeric shear elements. Elastomeric tension elements can be simply inserted in series with the main hoist rope. An elastomeric load compensator employing elastomeric torsion elements is mounted to the underside of the boom for receiving the live end of the main hoist rope. A single stack of elastomeric shear elements is suitable for mounting a hoist or winch or an idler sheave to the crane structure. For additional load compensation, the hoist, winch, and idler sheaves are mounted on rails for increased displacements under heave loads, and the increased displacements are compensated by elongated elastomeric tension elements or multiple elastomeric tension, torsion or shear elements in series.Type: ApplicationFiled: March 12, 2014Publication date: September 18, 2014Applicant: Oil States Industries, Inc.Inventors: Walter Billiot, Joseph Angeron, Danton Gutierrez-Lemini, Chris Chiasson, Eric Luke

Patent number: 8783293Abstract: A body includes two separate openings on a first side of the body that correspond to separate passages that converge to a common passage. An opening on a second side of the body couples to the common passage. A bore in the body is concentric with the common passage. A diverter has at least a part of the diverter in both the bore and the common passage. A tubular portion of the diverter has an open end in fluid communication with the common passage. One or more seals are positioned circumferentially around the part of the diverter located in the bore. The diverter is selectively rotated with the drive mechanism during use to align a diverter wall opening with a selected separate passage such that an object moving from the common passage through the tubular portion of the diverter is directed into the selected separate passage during use.Type: GrantFiled: January 18, 2011Date of Patent: July 22, 2014Assignee: Oil States Industries, Inc.Inventor: Bruce E.

Publication number: 20140069657Abstract: A freestanding hybrid riser system includes a steel pipe riser having a bottom end anchored to a foundation on a seabed through a flexible joint and a diverless pipe connector. A tube is mounted to the foundation and connected to the diverless pipe connector for providing a static connection to a subsea pipeline on the seabed for a flow of fluid between the steel pipe and the subsea pipeline and through the flexible pipe joint and through the diverless pipe connector and through the tube. In a preferred implementation, the flexible pipe joint includes alternate elastomer layers and metal layers reinforcing the elastomer layers, and a receptacle of the diverless connector is mounted on a foundation such as a suction pile on the seabed, or a pile grouted in a bore in the seabed.Type: ApplicationFiled: September 10, 2013Publication date: March 13, 2014Applicant: Oil States Industries, Inc.Inventor: Bao Duy Povloski

Patent number: 8128129Abstract: A double-ended flexible pipe joint has first and second extension pipes extending from opposite ends of an outer housing, and first and second primary annular elastomeric flex elements mounting the first and second extension pipes to the outer housing. An inner housing is disposed in the outer housing, and first and second secondary annular elastomeric flex elements disposed in the inner housing mount the first and second extension pipes to the inner housing. Tension upon the first and second extension pipes places each of the first and second primary flex elements and each of the first and second secondary flex elements in compression. The first and second secondary flex elements contain fluid pressure within the first and second extension pipes so that the first and second primary flex elements are not subjected to the fluid pressure within the extension pipes.Type: GrantFiled: July 15, 2009Date of Patent: March 6, 2012Assignee: Oil States Industries, Inc.Inventors: Danton Gutierrez-Lemini, George W.

Publication number: 20120032434Abstract: A flexible pipe joint has two annular elastomeric flex elements stacked in a co-axial fashion at an inner radius from a common center of rotation, and at least one elastomeric flex element disposed at an outer radius from the common center of rotation. The flex elements at the inner radius are coupled mechanically in series between the extension pipe and the housing of the flexible pipe joint, and the flex element at the outer radius is coupled mechanically in parallel with the series combination of the inner flex elements. The inner flex elements isolate the flex element at the outer radius from transport fluid, and the flex element at the outer radius reduces the axial compression of the inner flex elements. Thus, the inner flex elements may have a reduced radius and a different composition to handle a higher loading of heat and pressure.Type: ApplicationFiled: August 25, 2011Publication date: February 9, 2012Applicant: OIL STATES INDUSTRIES, INC.Inventors: Danton Gutierrez-Lemini, Todd M.

Patent number: 8016324Abstract: A flexible joint has an extension mounted to a housing for relative angular displacement. Two or more annular elastomeric flex elements are stacked in a co-axial fashion and joined mechanically to mount the extension to the housing so that the flex elements react in parallel to angular and axial displacements of the extension with respect to the housing so that tensile load upon the extension places each of the flex elements in compression to split and share the tensile load among the flex elements in proportion to their relative axial stiffnesses. Therefore, for a given housing size or footprint, the overall load capacity is increased, and the lifetime of the flexible joint is increased for a given load capacity. The flex elements may have a common center of rotation, and the flex elements may be disposed either on the same side of the center of rotation or on opposite sides.Type: GrantFiled: February 25, 2008Date of Patent: September 13, 2011Assignee: Oil States Industries, Inc.Inventors: Danton Gutierrez-Lemini, Todd M.
