ABSTRACT:
An internal tieback connector for a subsea wellhead housing has a body which lands on the wellhead housing. A funnel extends over the wellhead housing. An internal connector element carried by the body will engage a profile in the wellhead housing. A connector actuator when moved axially downward will actuate the connector element. A tube extends downward from the connector actuator and engages the bore of a casing hanger. A locking device employs slips to allow downward movement of the actuator but prevent upward movement. The locking device can be released. A running tool is hydraulically actuated for moving the actuator downward and releasing the actuator to disconnect the tieback connector.
