Abstract:
1. A reinforced offshore pipe defining a longitudinal axis, having two main ends, a first proximal end aimed to be close to the water surface and a second distal end aimed to be located in the depth of the water, comprising a core of elongate shape externally coated with at least one layer of composite material extending continuously from the first proximal end to the second distal end, the composite material comprising at least one tape wound outside and around said core, each of the at least one tape being made from reinforcing threads or fibers embedded in a matrix of thermoplastic resin, each of the at least one tape is wound around the core at a predetermined settable winding angle relative to the longitudinal axis of the elongate element, the winding angle for the at least one tape varying from the first proximal end to the second distal end along the longitudinal axis, thereby varying the mechanical strength from the first proximal end to the second distal end of the offshore pipe.
