A running tool () having an annulus seal assembly () and casing hanger () attached thereto may be sent into to the wellhead () to lock and preload the casing hanger () in a single trip. The running tool () may be rotated a first time to drop the annulus seal assembly on the casing hanger (), a first pressure may be applied axially above the annulus seal assembly to set the annulus seal assembly, the running tool may be rotated a second time to close a gap between the annulus seal assembly and the wellhead, and a second pressure may be applied axially above the annulus seal assembly to preload the casing hanger.
