1. A system, comprising:
a hanger comprising a radially-outer surface with a hanger surface texture;
a sensor configured to detect vibrations induced by the hanger surface texture as the hanger moves through a housing of a wellhead;
a controller configured to receive signals indicative of the vibrations from the sensor and to process the signals to determine a position of the hanger within the housing of the wellhead;
a first clamp coupled to the wellhead and configured to drive the housing of the wellhead radially-inwardly to cause engagement between the hanger surface texture and the housing of the wellhead, wherein the engagement comprises an annular seal between the hanger surface texture and the housing of the wellhead.
