Abstract: A system for wellbore operations and methods for use, the wellbore having a wellbore support structure, the system including a hoist subsystem for moving tubulars, a drive subsystem for rotating the tubulars, the drive subsystem releasably connected to the hoist subsystem forming a hoist/drive unit, and powered apparatus for moving the hoist/drive unit, or for moving the hoist subsystem separately.

Abstract: Systems and methods for wellbore operations which employ a drive subsystem for rotating tubulars releasably connected to a hoist subsystem for moving tubulars, the hoist subsystem and the drive subsystem movable as a unit or the subsystems movable independently of each other and the subsystems independently dockable at selected locations in the derrick. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).
