Abstract
A running tool for installing a casing hanger in a subsea conductor also serves to wash cement from the annulus surrounding the casing hanger. The running tool includes a tubular tool body which connects to a string of conduit. An internal sleeve mounts in the interior of the tool body for rotational movement only. A torque member lowers through the conduit to the internal sleeve for rotating the internal sleeve. A wash port extends from the interior of the tool body to the exterior of the tool body. An external sleeve mounts to the exterior of the tool body for axial movement between a closed position, closing the wash port, and an open position, opening the wash port. A linking mechanism between the internal and external sleeve causes rotary movement of the internal sleeve to move the external sleeve axially.
