Abstract: A system includes a hanger locking assembly configured to lock a hanger within a housing of a wellhead. The hanger locking assembly includes an energizing ring having one or more axially-extending passageways configured to receive and to support one or more control lines. An anti-rotation element extends between the energizing ring and the hanger to block rotational movement of the energizing ring relative to the hanger. A locking ring is in contact with the energizing ring, and axial movement of the energizing ring relative to the hanger drives the locking ring radially to engaged position in which the locking ring extends into a corresponding recess of the housing of the wellhead to block axial movement of the hanger relative to the wellhead.
