Device for protecting at least one pipe located at the bottom of a body of water, and associated fluid transport assembly

摘要

A device including a plurality of disconnected ballast elements (24) for a pipe (16). Each ballast element (24) has a lower surface (34) to be laid at the bottom (12) of a body of water (14) and an upper surface (32) delimiting at least one concave trough (38) for supporting the pipe (16A, 16B). A top cover (26) for protecting the pipe and connecting at least two disconnected ballast elements (24) so as to cover the pipe (16A, 16B) between the ballast elements (24). The cover (26) extends opposite the trough (38) and delimits, together with the upper surfaces (32) of each ballast element (24), a passage for receiving the pipe (16A, 16B).

1. A device for protecting at least one pipe located at a bottom of a body of water, the device comprising:
a plurality of disconnected ballast elements for the pipe arrayed along the pipe, each ballast element having a lower surface for being placed on the bottom of the body of water and an upper surface defining at least one trough for supporting the pipe; a top cover for protecting the pipe and connecting at least two of the disconnected ballast elements so as to cover the pipe between the ballast elements; the cover extending opposite the trough for delimiting, with the upper surface of each ballast element, a passage for receiving the pipe; the cover has substantially a cylinder section shape with a concavity oriented downward toward the trough; the cover has a lower surface opposite the trough, the lower surface having a minimum curve radius larger than a maximum curve radius of an upper surface of the ballast element; and wherein the lower surface of at least one ballast element has a convexity oriented downward toward the bottom of the water, and the lower surface of the at least one ballast element has a central region that is substantially parallel to an immobilization axis of the pipe disposed in the ballast element and has at least one peripheral region tilted toward the upper surface moving away from the central region along the immobilization axis.
