Patent number: 10767435Abstract: Embodiments of the present disclosure include a system for installing a slip hanger assembly in a wellbore with a slip bowl comprising an aperture extending from an outer diameter of the slip bowl. The system also includes a slip coupled to the slip bowl, the slip comprising teeth on an inner face and a slot for receiving a shear pin extending through the aperture. The system further includes a running tool coupled to the slip bowl. The system includes a housing coupled to the running tool, the housing including a cylinder for receiving a reciprocating piston, the piston being movable between a first position and a second position, wherein the slip is in stored position while the piston is in the first position and an engaged position when the piston is in the second position.Type: GrantFiled: July 18, 2018Date of Patent: September 8, 2020Assignee: GE OIL & GAS PRESSURE CONTROL LPInventors: Rodolfo Lugo, Andrew Helvenston, Gajanan Hegde, Satish Ramasheshaiah, Eugene Borak, Chijie Lin, Jean Brunjes

Patent number: 9945201Abstract: A wellhead assembly includes first and second wellhead members. An annular lock groove is located on an inner or an outer diameter surface of the first wellhead member. An annular lock ring is supported on an annular shoulder of the second wellhead member and is radially moveable between an unset position and a set position where a locking profile of the annular lock ring engages the annular lock groove. The second wellhead member is positioned concentrically with the first wellhead member, defining an annulus between the first and second wellhead members. An energizing ring is positioned in the annulus and axially movable between an unengaged position and an engaged position. The energizing ring has an engaging portion with a corrugated shape in cross section that is interference fit between the annular lock ring and the second wellhead member when the energizing ring is in the engaged position.Type: GrantFiled: April 6, 2016Date of Patent: April 17, 2018Assignee: GE Oil & Gas Pressure Control LPInventors: Donald James Tamosaitis, Chijie Lin

Patent number: 8882394Abstract: A coupler having two degrees of axial freedom couples a hydro-pneumatic cylinder to a tensioner ring of a riser tensioner mounted to a platform. A post extends along an axis of the cylinder and an intermediate sleeve is disposed around the post to form a post annulus. An outer sleeve is secured to the tensioner ring and defines a cavity into which the post and intermediate sleeve are inserted so that an annulus is formed between the sleeve and the outer sleeve. The Outer sleeve is coupled to the intermediate sleeve so that the outer sleeve may pivot on the coupling between the outer sleeve and the intermediate sleeve relative to the intermediate sleeve. The intermediate sleeve is coupled to the post so that the intermediate sleeve may pivot on the coupling between the intermediate sleeve and the post relative to the post.Type: GrantFiled: August 17, 2012Date of Patent: November 11, 2014Assignee: Vetco Gray Inc.Inventors: Bulent Aksel, Joseph William Pallini, Jr., Steven Matthew Wong, Philip John Potter, Chijie Lin

Patent number: 8265912Abstract: The present disclosure is directed to a computer-implemented method for modeling a mounting assembly having a mounting strap configured to couple a component to a bracket. The method includes modeling a loosened configuration of the mounting strap, wherein the loosened configuration provides a first substantially continuous curvature of portions of the mounting strap engaged with the bracket and the component. The method also includes applying simulated stresses to the mounting strap in the loosened configuration and outputting failure mode information of the mounting strap based on the simulated stresses on the mounting strap.Type: GrantFiled: December 19, 2008Date of Patent: September 11, 2012Assignee: Caterpillar Inc.Inventors: Ashok Rajendran, Chijie Lin, Chunhui Pan
