1. A hydraulic landing nipple assembly comprised of:
a control line port located at an outer surface of a tubular member having a bore therethrough;
an upper seal recess positioned above the control line port on the tubular member;
a lower seal recess positioned below the control line port on the tubular member;
wherein the upper seal recess and the lower seal recess each define locations within the bore to receive an upper locking mandrel and a lower locking mandrel of a subsurface safety valve;
wherein the upper seal recess receives an upper seal of the upper locking mandrel when an upper expander mandrel shifts downward and expands the upper seal;
a first shear pin locks the downward shift of the upper expander mandrel;
wherein the lower seal recess receives a lower seal of the lower locking mandrel when a lower expander mandrel shifts downward and expands the lower seal;
a second shear pin locks the downward shift of the lower expander mandrel;
and
wherein the upper lock mandrel and lower lock mandrel separately provide mechanical anchoring and sealing support for the subsurface safety valve.
