Abstract
A method and apparatus are disclosed for providing erosion protection to self-interlocking windings of a carcass layer of a flexible pipe. The method includes the steps of, via a wound sacrificial insert located over at least a portion of an inner facing surface of self-interlocking windings of a carcass layer, shielding at least a flow facing edge region of each self-interlocking winding from abrasive elements carried by a bore fluid flowing along a bore of the flexible pipe from an upstream to a downstream location.
