ABSTRACT:
A relatively light weight radial wire-line conveyance mechanism capable of sustained high pressure incorporated into a wire-line riser set-up and configured to allow multiple radial bends without sheaves. The conveyance mechanism includes a segmented tubular body structure capable of being pressurized and defining a radial arc of between 0 and 180 degree having a threaded coupling at each end for connection to riser tubular joints. The tubular body contains a series of connected tubular segments, each of which includes a longitudinal bore and a roller or ball assembly therein defining a pressurized wire-line pathway for receiving wire-line that passes through each of the tubular segments.
