Abstract: An actuator assembly includes a threaded shaft, a threaded nut that is threadably coupled to the threaded shaft, an annular ratchet positioned about the threaded shaft and comprising one or more tracks, and a pin that extends from the threaded shaft and into the one or more tracks. The threaded nut may include a first circumferentially-facing surface, the annular ratchet may include a second circumferentially-facing surface, and the first and second circumferentially-facing surfaces are configured to contact one another to enable the threaded nut to block rotation of the annular ratchet with the threaded shaft. The actuator assembly may enable the threaded nut to move to a limit position and hold full motor torque, but also to break free from the limit position with relatively low torque (e.g., less than the full motor torque; as compared to actuator systems that are devoid of certain features of the actuator assembly).

Abstract: A locking assembly and a retaining ring for retaining the locking assembly within a bore of a wellhead component are provided. In one embodiment, a system includes an inner component disposed within a bore of a wellhead component and a locking assembly disposed within the bore to secure the inner component within the bore. The locking assembly includes a lock ring that extends into a recess in a wall of the bore of the wellhead component and an actuator radially disposed between the inner component and the lock ring. The system also includes a retaining ring that limits movement of the actuator along the inner component and maintains the actuator between the inner component and the lock ring to retain the lock ring within the recess. The actuator and the retaining ring have mating tapered surfaces that inhibit movement of the actuator out of engagement with the lock ring.

Abstract: Rotating mandrel casing hangers are provided. In one embodiment, a system includes a casing hanger having a lower end configured to engage a casing string and a running tool configured to engage the casing hanger. The system is configured to facilitate rotation of the casing hanger within a casing head to rotate the casing string while cementing the casing string within a well. Additional systems, devices, and methods are also disclosed.

Abstract: A packoff and a locking assembly installed in a bore of a wellhead component are provided. In one embodiment, a packoff includes inner and outer annular seals and an energizing ring shaped to be wedged between the inner and outer annular seals so as to apply a radially inward biasing force on the inner annular seal and a radially outward biasing force on the outer annular seal. In another embodiment, a locking assembly includes a lock ring that extends into a recess in a wall of the bore of the wellhead component and an actuator radially disposed between an inner component within the bore and the lock ring to retain the lock ring within the recess. The actuator can have an interference fit with the inner component to inhibit movement of the actuator between the lock ring and the inner component. Additional systems, devices, and methods are also disclosed.
