Abstract
A wellhead system includes a first position casing hanger and a second position casing hanger, arranged within a wellbore. The second position casing hanger is positioned axially higher and stacked on the first position casing hanger, and a weight of the second position casing hanger is supported, at least in part but less than entirely, by the first position casing hanger and, at least in part but less than entirely, by an actuated load shoulder transferring the force into a high pressure housing. The actuated load shoulder includes a load ring having a hanger side profile and a housing side profile, the load ring is adapted to engage a hanger profile formed in the second position casing hanger and a housing profile formed in the high pressure housing upon activation via the first position casing hanger.
