Abstract: A seal assembly is provided. The seal includes an upper body; a lower body having a seal for sealing between a first wellhead system component and a second wellhead system component; and a space-out mechanism disposed between the upper body and the lower body, the space-out mechanism comprising a ramp ring having at least one tapered surface. The upper body has at least one tapered surface configured to interface with the at least one tapered surface of the ramp ring, the ramp ring is configured to rotate relative to the upper body and the lower body, and the at least one tapered surface of the ramp ring and the at least one tapered surface of the upper body are configured to bear against each other to rigidize the system.

Abstract: A system includes a seal assembly configured to retain a casing hanger within a wellhead. The seal assembly includes: a main body; a lock ring coupled to the main body and configured to expand radially outward into a profile on an inner diameter of the wellhead; and a wedge shaped component coupled to the main body and located under the lock ring, the wedge shaped component having a tapered upward facing surface that is capable of causing the lock ring to move axially upward in response to radially outward movement of the wedge shaped component.

Abstract: A system includes a seal assembly configured to retain a casing hanger within a wellhead. The seal assembly includes: a main body including at least one tapered surface on an upper end thereof; a lock ring coupled to the main body and configured to expand radially outward into a profile on an inner diameter of the wellhead; and a cam ring disposed above the main body and having at least one tapered surface on a lower end thereof, the at least one tapered surface of the cam ring interfacing with the at least one tapered surface of the main body such that rotation of the cam ring in a first direction with respect to the main body causes the lock ring to move axially upward.

Abstract: Systems and methods for landing a tubing hanger in a wellhead and then orienting a tree (or spool, or flowline connection body) relative to the tubing hanger while landing the tree on the wellhead are provided. This alignment is accomplished without the use of either a tubing spool or a BOP stack with an orientation pin. The tubing hanger alignment devices may be used to orientate the tree as the tree is landed so that the couplings and stabs between the tree and the tubing hanger line up with each other just at the moment of landing. A space-out mechanism is provided to take up any gaps formed axially by being picked up, thus rigidizing the tubing hanger and casing hanger within the wellhead.

Abstract: A hanger assembly includes: a main body; a lock ring coupled to the main body and configured to expand radially outward into a profile on an inner diameter of the wellhead; and an actuator, wherein the actuator is capable of transferring an axial force from the actuator into outward radial expansion of the lock ring toward the profile on the inner diameter of the wellhead. An interface between the actuator and the lock ring is shaped such that: axially downward movement of the actuator from a starting position to an intermediate position actuates the lock ring into the profile; and axially downward movement of the actuator from the intermediate position to a pre-load position applies a pre-load to the hanger assembly.

Abstract: A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. The subsea wellhead assembly may include a tubing hanger positioned in or below a wellhead housing coupled to a subsea well, a tree cap fluidly coupled to the tubing hanger and disposed atop the wellhead housing, and a pair of master production valves configured to be selectively actuated from an open position to a closed position to shut in the subsea well, each of the pair of master production valves located within or below the wellhead housing.
