摘要： The use of a buried or covered flexible sea-bed pipeline for transporting fluids is disclosed. The pipeline comprises a sealing barrier (3) and reinforcing layers (4, 5) capable of withstanding mechanical stress and arranged around said sealing barrier. The reinforcing layers consist of at least two crosswise-arranged reinforcing plies (4, 5) of wires helically wound at respective winding angles ai to the longitudinal axis of the pipeline, such that they comply with the following relationships: when i = 1, 2, ..., 52° ≤ ai ≤ 58°. The arithmetic mean am of said winding angles ai complies with the following relationship: 53° ≤ am ≤ 57°.
