ABSTRACT:
A riser pipe assembly is provided for interconnecting a subsea wellhead on an ocean floor with an above-surface platform. The assembly includes at least one cable extending generally between the wellhead and the platform to provide vertical support for the assembly. A plurality of support plates are fixed to the cable at predetermined spaced locations therealong. At least one riser pipe string extends between the wellhead and the platform and includes a plurality of riser pipes engaged end-to-end. In one embodiment of the invention, each riser pipe includes a lower bell-shaped end and an upper spigot-shaped end inserted into the bell-shaped end of the immediately adjacent riser pipe thereabove. The lower bell-shaped end of each riser pipe rests by gravity on and is supported by one of the support plates. In another embodiment of the invention, each riser pipe includes an upper bell-shaped end and a lower spigot-shaped end inserted into the bell-shaped end of the immediately adjacent riser pipe therebelow. The enlarged juncture of the upper bell-shaped end of each riser pipe rests by gravity on and is supported by one of the support plates.
