摘要
The invention relates to a method of producing an unbonded flexible pipe and an unbonded flexible pipe. The method comprises providing an innermost sealing sheath defining a bore and a longitudinal axis, and a pressure armor layer surrounding the innermost sealing sheath. The pressure armor layer comprises at least one helically wound elongate armor element with at least one helical armor element gap between windings thereof, and the method comprises providing a foundation layer for the pressure armor layer. The foundation layer is provided with at least one helically shaped groove, and the elongate armor element is applied in the helically shaped groove, preferably such that the foundation layer at least partly fills the helical armor element gap, the foundation layer is preferably a fluid permeable foundation layer.
