Hanger floating ring and seal assembly system and method

A wellhead, comprising:

• a hanger disposed in the wellhead;
• and
• a seal assembly disposed in the wellhead concentrically around the hanger and configured to seal a portion of the hanger, the seal assembly comprising:
• a first elastomeric seal moveable, after shearing a first shear structure, between a radially retracted position and a radially expanded position, wherein the first elastomeric seal is in the radially retracted position when the seal assembly is moved axially into the wellhead.

A wellhead, comprising:

• a hanger disposed in the wellhead;
• and
• a seal assembly disposed in the wellhead concentrically around the hanger and configured to seal a portion of the hanger, the seal assembly comprising:
• a first metal seal comprising a first plurality of rings disposed on a first seal body of the first metal seal, wherein the first plurality of rings comprises a first set of first nibs and a second nib, wherein the first set of first nibs are smaller than the second nib, wherein the second nib comprises a first flat surface configured to bear an energizing load for the seal assembly and the first nibs are configured to seal the seal assembly.
