Abstract: An annular seal system for sealing between a casing hanger and a wellhead housing, the system including an actuator ring having a rigid portion and a flexible portion, and a lockdown ring positioned adjacent the actuator ring. The annular seal system further includes a seal assembly capable of moving between a de-energized position and an energized position, wherein the seal assembly in the de-energized position has a defined a space between the seal assembly and the rigid portion of the actuator ring, wherein the seal assembly in the energized position has the space closed, wherein the rigid portion of the actuator ring is to contact a surface of the casing hanger, wherein the flexible portion of the actuator ring is to push the lockdown ring into engagement with the wellhead, and wherein the flexible portion of the actuator ring adapted is to axially compress to allow positional variation between the lockdown ring and the wellhead housing.
