ABSTRACT:
A drilling riser between a subsea wellhead and a floating platform has a slip joint in its upper end. A chamber is formed within the slip joint and supplied fluid pressure to develop a tensioning force on the upper end of the riser as the floating platform cycles vertically under the influence of heave and tidal forces.
