ABSTRACT:
Riser for an offshore marine platform which includes facilities to receive, treat, and/or store hydrocarbon fluid from a plurality of dispersed submerged wells. The riser includes means to accommodate a plurality of conduits between the platform deck and the floor of the body of water. As a rigid, or non-rigid conduit is pulled downwardly through the riser, it engages a deflecting shoe. The latter deflects the pulled conduit into a direction away from the platform and along the ocean floor, whereby it can readily engage a pipeline, or attach to one of the dispersed wells.
