A running tool for landing a tubular hanger in a subsea wellhead housing or the like, installing an annulus seal assembly into a sealing annulus between the tubular hanger and the wellhead housing, and then pressure testing the seal assembly. The running tool includes an inner mandrel which comprises an upper end that is connectable to a running string, a generally cylindrical inner body which is movably connected to the inner mandrel and releasably connectable to the tubular hanger, a generally cylindrical lower body which is positioned around the inner body above the tubular hanger and connectable to the seal assembly, a generally cylindrical upper body which is positioned above the lower body and is connected to the inner body, an outer mandrel which is slidably supported on the upper body and is connected to the lower body, and a first pressure chamber. |
