Systems and methods for rigidizing a seal

A method, comprising:

• positioning a seal assembly into a wellhead, the seal assembly comprising:
• a main body having at least one tapered surface on an end thereof;
• a lock ring coupled to the main body;
• at least one ramp coupled to a radially inner surface of a cam ring;
• and
• the cam ring coupled to the main body and having at least one tapered surface on an end surface thereof, the at least one tapered surface of the main body interfacing with the at least one tapered surface of the cam ring;
• actuating the lock ring of the seal assembly toward a profile on an inner diameter of the wellhead;
• during or after actuating the lock ring, adjusting an axial length of the seal assembly by rotating the cam ring in a first direction with respect to the main body, wherein a rotational movement of the cam ring causes the lock ring to move axially upward;
• and
• retaining a casing hanger in the wellhead via the seal assembly.
