摘要： A hose includes a generally cylindrical tubular structure with at least one layer of steel ligaments near the outer surface, the steel ligaments being enclosed within a tubular layer including polymeric material; the flexible hose also incorporates a multiplicity of sensing coils embedded within the tubular layer, each such sensing coil being a flat coil lying in a plane substantially parallel to the adjacent layer of steel ligaments, so that an axis of the coil orthogonal to the plane of the flat coil extends in a radial direction relative to the hose. Each such sensing coil may form part of an electronic module that also incorporates a signal processing circuit and an RE power-receiving and data-transmission circuit. When that portion of the hose is subjected to an alternating magnetic field, signals from the sensing coils can be analysed to deduce information about the stress in the steel ligaments.

摘要： A method, a component part of an end fitting and a preformed member for manufacturing a component part of an end fitting are disclosed. The method comprises the steps of, via an additive process, providing a near net shape (NNS) precursor corresponding to a component part of an end fitting layer-by-layer and subsequently performing at least one post NNS processing operation on the NNS precursor to provide the component part.

摘要： A flexible pipe and method of producing a flexible pipe are disclosed. The method includes bending armour wires of a flexible pipe body about 10 to 50 degrees from a longitudinal axis of the pipe body using a temporary collar member; inserting a further collar member radially inwards of the bent armour wires such that a portion of the armour wires lay over the further collar member; and mating the flexible pipe body and further collar member with an end fitting body.

摘要： A detection apparatus and method arranged to detect defects within a flexible pipe at least partially surrounded by seawater. The detection apparatus comprises a seawater electrode, an impedance monitor and a processor. The seawater electrode is arranged to be in contact with seawater surrounding at least part of a flexible pipe. The impedance monitor is arranged to measure the impedance between a metallic structural component of the flexible pipe extending at least partially along the length of the flexible pipe and the seawater electrode in response to an electrical test signal applied to the seawater electrode. The processor is arranged to determine the distance from the seawater electrode to a pipe defect electrically connecting the metallic structural component to seawater using the measured impedance.

摘要： 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.

摘要： A method of applying acid-wash to a subsea connection assembly, in particular a stabplate connection, in order to remove unwanted material such as marine growth and calcareous deposits. The method consists of inserting a plug, containing channels, into a central in a stabplate connection and injecting acid-wash through the plug. The plug may be carried by an operating tool arm of a remotely operated underwater vehicle (ROV).

摘要： Embodiments of the present disclosure include a system for directing the flow of fluids via a production tree. The production tree extends upwardly from a lower surface to an upper surface and at least partially enclosing an upper section of a production bore and an upper section of an annulus bore, wherein one of a lower section and the upper section of the production bore includes a first production valve, the upper section of the production bore includes a second production valve, and the upper section of the annulus bore includes a second annulus valve.

摘要： To produce a flexible pipe body, a length of tensile armour element (300) of pre-preg composite material is fed towards a fluid-retaining layer (602). The tensile armour element (300) passes through a guide (604) an a pre-heater (606). The tensile armour element (300) is then applied to the fluid-retaining layer (602), being wrapped around the fluid-etaining layer (602) by virtue of the rotation of the layer (602), the linear translation of the layer (602), and the fixed position of the tensile armour element feed (601). The element (300) is fed to the fluid-retaining layer under a constant, predetermined controlled tension. Positioning head (608) helps to position the element (300) on the fluid-retaining layer (602). As tensile armour element is wound onto the pipe body, the pipe body continues to move in a, linear direction and the pipe body moves through an oven (610).
