Abstract: A clamp for coupling two tubular members together includes an annular body. The clamp also includes a plurality of fixed segments that are configured to be secured at least partially within a recess formed in an inner surface of the body. The fixed segments are circumferentially offset from one another with respect to a central longitudinal axis through the body. The fixed segments are configured to exert a downward force on a first hub of a first tubular member. The clamp also includes a plurality of clamping segments that extend radially through the body. The clamping segments are circumferentially offset from one another. The clamping segments are axially offset from the fixed segments. The clamping segments are configured to actuate between a retracted position and an extended position. The clamping segments in the extended position are configured to exert an upward force on a second hub of a second tubular.

Abstract: Various wellhead assemblies are provided. In one embodiment, the wellhead assemble includes a seal assembly that seals against an inner surface of a wellhead hanger and against an inner surface of a wellhead body. The wellhead hanger can be sized such that the upper portion of the hanger has an outer surface that abuts an inner surface of the wellhead.

Abstract: In certain embodiments, a hanger running tool includes an inner sleeve and an outer sleeve. The inner sleeve has a first mating surface configured to engage a second mating surface of a hanger to couple the inner sleeve to the hanger. The outer sleeve is disposed about the inner sleeve. The outer sleeve is configured to rotate about a common longitudinal axis with respect to the inner sleeve.
