Swivel

摘要

The present invention is directed to swivel means for use in connecting pairs of axially spaced risers in an off-shore multi-line riser system the conveys petroleum from a collection point on the ocean floor to a floating buoy for delivery to tankers. The swivel permits considerable latitude in the movement of the riser system yet assuring leak proof joints at the points of movement by providing elastic seals that facilitate motion between conveying conduits.
