  • Patent number: 10683951
    Abstract: An elongate tape element (508), a flexible pipe body and method of producing a flexible pipe body are disclosed. The tape element has a cross-sectional profile comprising a body portion (510) for being positioned between collapse resistant tape windings such that each body portion lies at least partially in a gap (512) between adjacent collapse resistant tape windings (501); and at least one wing portion (516) extending from an end region of the body portion (510), the at least one wing portion (516) configured to span the gap (512) and respectively abut with a radially inner surface of an adjacent collapse resistant tape winding (501).
    Type: Grant

  • Patent number: 10274396
    Abstract: A flexible pipe body comprising an elongate curvature sensor and a tensile armor layer. The elongate curvature sensor incorporates a strain sensor arranged to provide an indication of bending strain applied to the curvature sensor. The tensile armor layer comprises helically wound tensile armor wires. The curvature sensor is positioned within the tensile armor layer helically wound adjacent to at least one tensile armor 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 armor wire in at least one of depth and width and arranged to slide longitudinally relative to the adjacent tensile armor wire.
