ABSTRACT:
A piping or conduit system in which conduits to receive flow lines or flexible pipe can be connected end to end to form a riser assembly, and thereafter, the flow lines can be inserted through individual conduits of the assembly. The section contains a low density foam to impart essentially zero negative and positive buoyancy, and the foam is filled into areas surrounding the individual conduits of the sections. Suitable reinforcing and tension stress resisting elements are provided so that each section is essentially self sustaining.
