Zusammenfassung:A hanger running tool 10 for installation of a hanger 14 in a well. The hanger running tool comprises a central bore 30 and a hanger engagement arrangement 26 configurable between an engaged position in which the engagement arrangement is coupled to a hanger, and a disengaged position in which the engagement arrangement is decoupled from a hanger. The tool also comprises a pressure-controlled anchoring actuator 42 for actuating an anchoring arrangement, and comprising an actuation surface 42a. The hanger engagement arrangement is configurable to the engaged position in response to an increase in pressure at a first pressure source, and is configurable to the disengaged position in response to an increase in pressure inside the central bore. The anchoring actuator is actuated in response to an increase in pressure on the actuation surface (e.g. an increase in pressure external to the tubing hanger running tool, such as an increase in the pressure in the BOP, below the slick joint) so that the anchoring arrangement anchors the hanger to an anchor point, which may be located on the wellhead, the Xmas tree, the BOP, or the like.
