Unbonded flexible pipe

An unbonded flexible pipe having a length and a longitudinal axis and comprising, from the inside and out,

• a carcass made from an electrically conductive material,
• an internal pressure sheath made from an extruded polymer,
• at least one external armor layer and an outer sheath,
• the carcass being adapted for connection to an electric power source for conducting an electric current, at least a part of the external armor layer being electrically conductive, the carcass and the external armor layer allowing a difference in electric potential to be established partly or fully over the internal pressure sheath, wherein the internal pressure sheath is partly or fully covered by a conforming cover layer made from a material which is electrically conductive and having a bulk resistance larger than the specific resistance of the electrically conductive material of the carcass and wherein the conforming cover layer is located between the internal pressure sheath and the external armor layer.
