Abstract: A flexible pipe body for a flexible pipe for transporting production fluid from a sub-sea location. The flexible pipe body includes an inner sheath layer for retaining fluid within a bore of the flexible pipe body and an outer sheath layer provided radially outwardly of the inner sheath layer. An abrasion layer is provided radially outwardly of the outer sheath layer for protecting the outer sheath layer against abrasion damage. A reinforcement layer is provided between the outer sheath layer and the abrasion layer, for protecting the outer sheath layer against impact damage. The reinforcement layer includes filaments that are woven, braided, knitted or otherwise intertwined.

Abstract: A test apparatus (12) and a method of testing a sample (30) are disclosed. The method comprises receiving a test sample (30) within a test chamber (14), the test chamber (14) containing two or more iron saturation elements (2) separated by a spacer (16); and filling the test chamber (14) with a test solution, the iron saturation elements (2) being arranged to saturate the test solution with iron. Each iron saturation element (2) is shaped such that it has a predetermined surface area such that the ratio of the volume of the test solution to the surface area of the iron saturation elements (2) and the test sample (30) exposed to the test solution can be calculated.

Abstract: An assembly and method of testing the integrity of a sealing ring of a flexible pipe are disclosed. The method includes locating a first sealing ring adjacent a first collar member and a layer of flexible pipe body; energizing the first sealing ring by urging the sealing ring towards a primary pressure-retaining end fitting component, or by urging the pressure-retaining component towards the sealing ring; locating a second sealing ring adjacent the first collar member and a second collar member; energizing the second sealing ring by urging the sealing ring towards the pressure-retaining component, or by urging the pressure-retaining component towards the sealing ring; and pressurizing the region between the first sealing ring and the second sealing ring through a port extending towards the region to a predetermined pressure of 5 MPa or greater.

Abstract: A riser or jumper assembly for transporting production, exportation or injection fluids is disclosed as is a method for providing buoyancy to such an assembly. The riser or jumper assembly includes a first segment of flexible pipe comprising a portion of flexible pipe body and a first and second end fitting, a further segment of flexible pipe comprising a portion of flexible pipe body and a first and second end fitting and an intermediate segment of flexible pipe comprising a portion of flexible pipe body and a first and second end fitting and at least one buoyancy element.

Abstract: A riser assembly for transporting fluids from a sub-sea location is disclosed. The riser assembly includes a riser having at least one segment of flexible pipe and a plurality of buoyancy compensating elements connected to the riser and connected together in an in-line configuration to form a mid-line buoyancy section. The riser assembly also includes at least one buoyancy aid connected to the riser at a position above and spaced apart from the mid-line buoyancy section. The at least one buoyancy aid forms a first distributed buoyancy section and is sufficiently buoyant to maintain a tension load on the riser between the first distributed buoyancy section and the mid-line line buoyancy section. The riser assembly further includes at least one further buoyancy compensating element connected to the riser at a position above and spaced apart from the first distributed buoyancy section to form a second distributed buoyancy section.

Abstract: A sealing arrangement and a method for testing the integrity of a sealing arrangement of a flexible pipe are disclosed. The method includes locating a first annular sealing element and a second annular sealing element in a joint between two elements of a flexible pipe, with a region of the joint therebetween; and pressurizing the region between the first sealing element and the second sealing element through a port extending towards the region to a predetermined pressure of 0.2 MP or greater.

Abstract: A sleeve member, end fitting assembly, and a method of assembly of a flexible pipe are disclosed. The sleeve member includes a body comprising a substantially cylindrical portion having an inner diameter substantially equal to an outside diameter of a first pipe body layer for overlying the first pipe body layer; and a flange portion extending radially outwards from the body for locating between a further pipe body layer and an end fitting, the further pipe body layer being an armor layer, the flange portion having an outer diameter substantially equal to or greater than the outer diameter of the further pipe body layer.

Abstract: An apparatus and method are disclosed for protecting an outer layer of a flexible pipe. The apparatus includes a protective sleeve body comprising a first end region and a further end region. At least one connector element is also provided which is securable to the first end region of the sleeve body for securing the sleeve body with respect to a flexible pipe located proximate to a wear hazard. The sleeve body is securable uncovered over a portion of an outer sheath of the flexible pipe between the outer sheath and the wear hazard to provide a protected portion of flexible pipe having a bending stiffness substantially equal to a bending stiffness of a remaining portion of the flexible pipe which is uncovered by the sleeve body.
