Abstract
A conductor tieback connector for connecting a conductor to a subsea wellhead includes a downwardly extending funnel. Two bearing rings within the funnel interact with the outside surface of the wellhead to generate bending forces to force the tool in alignment with the wellhead. Thereafter a separate lockdown nut secures the connector to the wellhead without rotation of the conductor.
