ABSTRACT:
A pipeline is forced into a borehole using a deadman disposed directly in front of the entry to the borehole. A force is generated between the deadman and a collar attached to the pipeline such that the pipeline is forced through the deadman into the borehole. The force may be generated by a cable and sheave combination or through hydraulic cylinders.
