ABSTRACT:
Modular vertical floating pipe comprising a plurality of modules, each module formed by (a) two pipe segments of slightly different diameter, the lower segment with the smaller diameter segment joined by a collar with the upper pipe segment and (b) an annular floater of such dimensions that could slide up only in the lower vertical segment. A longer pipe would be formed by inserting one module on top of another, and repeating the operation until all modules have been utilized. The additional weight of a new module will be pushing the section of the pipe already formed down. The difference in diameter between the upper and lower segments will allow the pipe to bend with undersea currents. Appropriate seals will dampen the bending movements and cabling supporting a weight attached to cabling guides will prevent disengagement of the modules. By tying the cable to the top floater, the long pipe could be lowered and disconnected from the platform, allowing the platform and the pipe to ride a threatening storm independently.
