ABSTRACT:
A connector for tying back a wellhead (10) to a floating platform rigidly attaches to the wellhead housing (12). It is engaged with the casing hanger (14) through a bellows (86) arrangement. Strain cycling of the connection is reduced while thermal expansion and manufacturing tolerance are readily tolerated.
