摘要 |
A method for laying underwater pipelines in deep water, using the J launching technique, comprising joining together mixed-structure pipes consisting of a steel core reinforced with a composite material consisting of a hardenable material containing continuous fibres and in which: the continuous fibre is wound about the steel core as a helical winding which forms an angle of between 65 and 87 DEG with the pipe axis; the ratio of the thickness of the composite layer to the thickness of the steel core is between 2 and 8; the weight of the mixed-structure pipe in water is between about 40 and 100 kg/m. |
