Abstract: An unbonded flexible armored pipe for transportation of fluids. The pipe has a center axis and a length and includes a carcass and an innermost sealing sheath with an inner surface surrounding the carcass. The carcass includes at least one elongate armor element wound to surround the center axis with a winding angle to the center axis defining a winding direction and a supporting surface facing towards the inner surface of the innermost sealing sheath and with a supporting surface radius Sr. The supporting surface includes a primary surface area and a plurality of restraining regions in the form of orifices in and/or protuberances and/or indentations from the primary surface area, wherein the restraining regions each have a length determined along the winding direction of the elongate armor element which is up to about Sr times Π.

Abstract: The present invention relates to a method of testing an unbonded flexible pipe. The unbonded flexible pipe has a length and a longitudinal axis and comprises, from the inside and out, an internal armour layer, an internal pressure sheath, at least one external amour layer and an outer sheath. At least one of the layers comprises an optical sensor connected to an optical monitoring system and at least one of the armour layers is a metallic and electrically conductive amour layer. The method makes it possible to test an electrical heating system and an optical sensor substantially simultaneously.
