Abstract
A subsea wellhead assembly includes a housing with a bore containing at least one conical generally upward facing load shoulder that inclines relative to an axis of the bore. A hanger is lowered into the housing, the hanger having at least one conical downward facing load shoulder that inclines at a lesser inclination relative to an axis of the bore than the upward facing load shoulder. A split load ring has an inner profile that slidingly engages the downward facing load shoulder and an outer profile that slidingly engages the upward facing load shoulder. The load ring is carried by the hanger for movement between a retracted position, wherein the outer profile is spaced radially inward from the upward facing load shoulder, and an expanded position wherein the outer profile is in engagement with the upward facing load shoulder.
