Patent number: 11976534Abstract: An apparatus includes a valve coupled to a pressure-containing component of a wellhead assembly. The pressure-containing component can include a hollow body, a bore within the hollow body, and an access passage that is in the hollow body and is in fluid communication with the bore. The valve can include a sealing element that is positioned along the access passage and is selectively moveable between closed and open positions to control fluid flow through the access passage. During operation, the sealing element may be moved between the closed and open positions without actuating the sealing element through an outer end of the access passage. Additional systems, devices, and methods are also disclosed.Type: GrantFiled: June 3, 2020Date of Patent: May 7, 2024Assignee: Cameron International CorporationInventors: Kirk P. Guidry, Dennis P.

Patent number: 10450822Abstract: A system includes a hanger locking assembly configured to lock a hanger within a housing of a wellhead. The hanger locking assembly includes an energizing ring having one or more axially-extending passageways configured to receive and to support one or more control lines. An anti-rotation element extends between the energizing ring and the hanger to block rotational movement of the energizing ring relative to the hanger. A locking ring is in contact with the energizing ring, and axial movement of the energizing ring relative to the hanger drives the locking ring radially to engaged position in which the locking ring extends into a corresponding recess of the housing of the wellhead to block axial movement of the hanger relative to the wellhead.Type: GrantFiled: October 5, 2016Date of Patent: October 22, 2019Assignee: Cameron International CorporationInventors: Sebastien Noel Albert Bories, Patrice Paul Louis Couren, Brandon Blake Shirley, Si Hui Koh, Haw Keat Lim
