ABSTRACT:
A collapsible parachute is propelled through a pipeline by flow of the pipeline contents. The parachute tows a pipeline profiling device which may include spring loaded feeler arms. The parachute collapses in order to pass obstructions or constrictions in the pipeline, and the feeler arms of the profiling device retract to avoid becoming stuck in the pipeline.
