1. A method of installing a casing hanger in a wellhead, comprising:
lowering a tool assembly into a wellhead, wherein the tool assembly comprises a running tool with a casing hanger and an annulus seal assembly removably attached thereon;
landing the casing hanger into the wellhead;
landing the annulus seal assembly on the casing hanger;
locking the casing hanger and the annulus seal assembly within the wellhead;
preloading the casing hanger within the wellhead; and
raising the running tool out of the wellhead after completion of the preloading;
wherein landing the annulus seal assembly on the casing hanger comprises;
engaging a first anti-rotation device of the running tool between an energizing mandrel of the running tool and an outer body of the running tool to prevent the annulus seal assembly from rotating,
disengaging a second anti-rotation device between an inner mandrel of the running tool and the outer body, and
rotating the inner mandrel of the running tool until the inner mandrel disengages with the energizing mandrel to land the annulus seal assembly onto the casing hanger, and
wherein the lowering, landing, locking, and preloading steps are completed in a single trip of the running tool being lowered to the wellhead and returned from out of the wellhead.
