ABSTRACT:
A method and apparatus for the promoting movement of a cable-like element in a selected direction in a pipe with the assistance of a flowing agent moving in the selected direction in the pipe include the use of profiles arranged on the external surface of the cable-like element to produce turbulence which promotes co-movement of the cable-like element in the pipe, together with the flowing agent in the selected direction. A number of different turbulence generating flow promoting structures for the profiles are disclosed.
