Embodiment Construction

[0051] In this specification reference will be made to flexible pipe. It should be understood that a flexible pipe is an assembly of a portion of a pipe body and one or more end fittings in each of which a respective end of the pipe body terminates. figure 1 It is shown how the pipe body 100 is formed from a composite of layered materials making up a pressure containment conduit in accordance with an embodiment of the present invention. Although in figure 1 A number of specific layers are shown, but it should be understood that the invention is broadly applicable to composite pipe body structures comprising two or more layers of various possible materials. Also note that layer thicknesses are shown for illustrative purposes only.

[0052] like figure 1 As shown, the pipe body includes an optional innermost carcass layer 101 . The carcass provides an interlocking structure that can be used as the innermost layer to fully or partially prevent the internal pressure sheath 102...

Abstract

Flexible pipe body for transporting fluids from a sub-sea location, including a carcass layer comprising a plurality of independent hoop elements each comprising a body portion having a circular outer surface that circles around an inner circumference of a bore region of the flexible pipe, said body portion being arranged to interlock adjacent hoop elements together. A method of manufacturing flexible pipe body is also enclosed.

Description

technical field [0001] The present invention relates to methods and apparatus for providing a flexible pipe body having a carcass layer. In particular, but not exclusively, the invention relates to a carcass layer comprising individual hoop elements formed as a plurality, wherein associated hoop elements are arranged side by side in rows and interlocked together. Background technique [0002] Traditionally, flexible pipes have been used to transport production fluids, such as oil and / or gas and / or water, from one location to another. Flexible pipe is particularly useful in connecting a subsea location to another subsea location or a sea level location. Flexible pipe is generally formed as an assembly of a flexible pipe body and one or more end fittings. The pipe body is generally formed as an assembly of layered materials constituting a fluid and pressure containing conduit. The tube structure allows for large deflections without causing bending stresses that impair tube ...
