ABSTRACT:
A device for positioning a pipeline intended to rest on the bottom of the sea or of a body of water. In order to present a resistance to the drifting of the pipeline by the action of cross-currents, the pipeline is provided with a plurality of support members suitably distributed along the pipeline and extending in a direction generally parallel to the vertical plane containing the longitudinal axis of the pipeline. The support members project below the pipeline towards the bottom and are deformable in the vertical plane by the reaction of the bottom on the support members, but are transversely rigid.
