ABSTRACT:
An apparatus for inserting or removing a string of tubulars from a borehole includes a makeup/break out mechanism which is capable of adding a tubular to or removing a tubular from the string and handling mechanism which feeds a tubular into, or removes a tubular from, the make up/break out mechanism. The make up/break out mechanism is moveable along the direction parallel to the axial direction of the string, such that the string may be substantially continuously inserted into or removed from the borehole.
