Abstract
A hanger assembly for supporting a tubular member within an outer well member includes a slip bowl that is moveable between an expanded condition with an enlarged diameter and a contracted condition with a reduced diameter, and has a downward facing slip bowl shoulder on an outer diameter of the slip bowl. Slips with teeth on an inner diameter surface are carried by the slip bowl. The slips are moveable between a retracted position, and an extended position where the teeth protrude radially inward from the inner diameter of the slip bowl. A false bowl has a lower upward facing false bowl shoulder located on an inner diameter and is sized to selectively engage the downward facing slip bowl shoulder. The false bowl also has a downward facing landing shoulder located on an outer diameter that is sized to selectively engage a support shoulder of the outer well member.
