Patent number: 10337655Abstract: A flexible pipe joint has a body and an annular elastomeric flexible element flexibly coupling an extension pipe to the body for pivoting of the extension pipe with respect to the body. The flexible pipe joint also has an annular flexible boot for thermally or chemically insulating the annular elastomeric flexible element from the fluid flowing through a lumen of the flexible pipe joint. The annular flexible boot encircles the lumen, and the annular flexible boot has a first annular end attached to the extension pipe and a second annular end mounted so that pivoting of the extension pipe with respect to the body causes a flexing of the annular flexible boot, and a majority of the annular flexible boot has a shape conforming to shape of neighboring components of the flexible pipe joint.Type: GrantFiled: May 27, 2016Date of Patent: July 2, 2019Assignee: OIL STATES INDUSTRIES, INC.Inventors: James G. Patrick, Eric Luke, Danton Gutierrez-Lemini

Patent number: 9845910Abstract: A pressure compensator for providing pressure compensation for a chamber of a subsea device is provided. The pressure compensator has an enclosure with at least an outer wall. A first compensation chamber is provided inside the enclosure. A flow connection from the first compensation chamber towards the chamber of the subsea device is further provided. As second compensation chamber is provided inside the enclosure. First and second separating walls are arranged inside the enclosure. A first bellows portion of the first separating wall and a second bellows portion of the second separating wall are deformable to provide pressure compensation between the chamber of the subsea device and a second inner volume around which the second separating wall extends.Type: GrantFiled: December 30, 2015Date of Patent: December 19, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventor: Gregor Knoener

Patent number: 8881846Abstract: Disclosed are systems and methods of directional drilling with a steering sub. One steering sub includes a housing defining a central passage, a shaft extended within the central passage, bearings arranged within the central passage and configured to receive and support the shaft for rotation within the central passage, and one or more pressure chambers defined longitudinally in the housing and configured to deflect the housing upon experiencing an increased pressure, wherein deflection of the housing causes the shaft to correspondingly deflect via engagement with the bearings.Type: GrantFiled: December 21, 2012Date of Patent: November 11, 2014Assignee: Halliburton Energy Services, Inc.Inventor: Mark A. Sitka

Patent number: 7762337Abstract: The invention relates to a riser pipe section comprising a main tube (2), at least one auxiliary line element (3) substantially parallel to said main tube (2) and at least two fastening means (7, 8) that connect the ends of said element (3) to main tube (2). The section is characterized in that fastening means (7, 8) allow longitudinal stresses to be transmitted from said element (3) to main tube (2) and in that at least one of fastening means (7, 8) allows at least a rotating motion of said element (3) in relation to said main tube (2), the rotating motion following an axis perpendicular to the plane passing through axis (4) of the main tube and through the axis of auxiliary line element (3).Type: GrantFiled: October 4, 2006Date of Patent: July 27, 2010Assignee: Institut Francais du PetroleInventors: GĂ©rard Papon, Jean Guesnon

Patent number: 7216726Abstract: A downhole tool comprises a joint, and a resilient member 65 which extends through the joint and provides a restoring force which tends to strengthen the joint. The joint may comprise a flex coupling 61 which allows limited articulation of the joint. First and second drill string sections 63, 64 may be interconnected by the joint, the resilient member 65 being fixed to interior surfaces of the first and second drill string sections 63, 64. A downhole tool may also comprise primary and secondary sleeves 46 that are supported relative to the mandrel 10 of the drill string. Rotational drive may be transferred from one of the sleeves to the other.Type: GrantFiled: June 10, 2002Date of Patent: May 15, 2007Assignee: Pilot Drilling Control LimitedInventors: George Swietlik, Joseph Fitzgerald

Patent number: 5813286Abstract: A support arm has stationary support structure, a boom, a knuckle and an auxiliary jib section. The boom connects at one end to the support structure and at an opposite end to one end of the knuckle, and an opposite end of the knuckle connects to one end of the auxiliary jib section. Each connection is a pivotal connection for pivoting about vertical pivot axes. An opposite end of the auxiliary jib section connects to a main jib section through a pivotal connection for pivoting about a horizontal axis. First and second flexible tubes connect across the knuckle and the auxiliary jib section between the boom and the main jib section. The flexible tubes extend from points on the main jib section in parallel horizontally spaced relationship and pass slippingly and in parallel longitudinally through parallel horizontally spaced guide sleeves that are connected on the auxiliary jib section.Type: GrantFiled: April 4, 1996Date of Patent: September 29, 1998Inventor: Henning Hansen
