Patent number: 11952856Abstract: An electric bonnet includes a housing; a guide piston disposed in the housing; an electric motor having a motor shaft; a rear housing connected to the housing; a gearbox assembly disposed in the rear housing, the gearbox assembly being coupled to the motor shaft of the electric motor; and a roller screw assembly disposed in the rear housing. A first end of the roller screw assembly is connected to the gearbox assembly, and a second end of the roller screw assembly is connected to the guide piston. Rotation of the motor shaft of the electric motor transmits rotary motion to the gearbox assembly, which transforms the rotary motion into linear motion using the roller screw assembly. The linear motion of the roller screw assembly actuates the guide piston.Type: GrantFiled: June 2, 2022Date of Patent: April 9, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Suman Katanguri, Todor K. Sheiretov, Bruce Boulanger

Patent number: 10704712Abstract: A pressure-energized ring joint gasket such as a CX gasket for a clamp or other connector includes a cylindrical inner surface oriented toward adjacent sections of a subsea stack that are to be joined by the connector, wings that taper away from the cylindrical inner surface and end in a rectangular shoulder, wherein a portion of the rectangular shoulder is removed to create a boss, an upper groove, and a lower groove, and D-rings in the upper and lower grooves. The gasket can be used to connect adjacent sections of the stack and to maintain a seal between the sections whether the external sea water pressure is greater or less than the internal well pressure. A method for using the gasket for connecting adjacent sections of a subsea stack in offshore drilling environments is also provided.Type: GrantFiled: December 17, 2015Date of Patent: July 7, 2020Assignee: CAMERON INTERNATIONAL CORPORATIONInventor: Bruce Boulanger
