  • Publication number: 20200080674
    Abstract: A method and apparatus are disclosed. The apparatus includes a securing element body comprising a first elongate weakened region in the body extending along a respective first weakened region axis, a further elongate weakened region substantially orthogonal to the first weakened region axis and located proximate to a first end of the first weakened region, and a still further elongate weakened region substantially orthogonal to the first weakened region axis and located proximate to a remaining end of the first weakened region, wherein the further and still further weakened regions are disposed in a substantially parallel spaced apart relationship to provide at least one deformable region in the securing element body on a respective side of the first elongate weakened region.

  • Patent number: 9976681
    Abstract: A fluid sealing element, a fluid sealing assembly, a method of providing a fluid seal, and a method of terminating a flexible pipe body in an end fitting are disclosed. The fluid sealing element (802) has an annular body portion locatable between an end fitting body (801) and an inner collar member (808) of an end fitting, and a tapered portion extending substantially perpendicular to the annular body portion at a radially inner region thereof. The method includes urging a fluid retaining layer (804) of a flexible pipe radially outwardly against an abutment surface of the inner collar member of the end fitting.
