ABSTRACT:
An unarticulated riser pipe for connecting a subsea pipeline to facilities on a floating platform. The riser pipe has a vertical section which is rigidly attached to a horizontal section which provides flexibility. Means are provided to maintain the tension on the vertical section. In one embodiment, a subsea frame aids in connecting the horizontal and vertical sections and then to set a limit on permitted motion of the riser pipe.
