A flexible pipe body comprising an elongate curvature sensor and a tensile armour layer. The elongate curvature sensor incorporates a strain sensor arranged to provide an indication of bending strain applied to the curvature sensor. The tensile armour layer comprises helically wound tensile armour wires. The curvature sensor is positioned within the tensile armour layer helically wound adjacent to at least one tensile armour wire such that bending strain applied to the flexible pipe body is transmitted to the curvature sensor The curvature sensor is smaller than an adjacent tensile armour wire in at least one of depth and width and arranged to slide longitudinally relative to the adjacent tensile armour wire. |
