Abstract
A technique facilitates deployment and operation of a casing hanger. A ratchet mechanism may be positioned between the casing hanger and a running tool. The ratchet mechanism may comprise a center body section located between a first cam, e.g. a lower cam, and a second cam, e.g. an upper cam. The first cam is constructed for releasable engagement with the casing hanger and the second cam is constructed for engagement with the running tool. The first cam has a cam profile which causes rotation of the casing hanger when the running tool is rotated in a first direction and which causes the ratchet mechanism to release from the casing hanger when the running tool is rotated in a second direction. Additionally, the second cam also may have a cam profile configured to force the ratchet mechanism toward the casing hanger when the running tool is rotated in the first direction.
