Problems solved by technology

Fibers that are not bonded to the steel pipe can be used to determine temperature or measure acoustic signals; however, in order to measure strain, the fiber must be fixed to the pipe and thus subjected to load transfer from the pipe
[0013] Additionally, the difficulty may lie in making a FIMT in which the fibers are bonded to the tube without unduly straining the fibers.

Embodiment Construction

[0043] This description will refer to flexible pipe throughout. 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 tubular body 100 is formed from a combination of layered materials forming a pressure-bearing conduit in accordance with an embodiment of the present invention. although figure 1 A number of specific layers are shown, but it is to be understood that the invention is broadly applicable to coaxial tubular body structures comprising two or more layers made of every possible material. It should also be noted that layer thicknesses are shown for illustrative purposes only.

[0044] Such as figure 1As shown in , the tubular body includes an optional innermost carcass layer 101 . The skeleton provides an interlocking configuration that can be used as an innermost layer to fully or partially prevent collapse of t...

Abstract

An elongate element (300) for a flexible pipe body (100) and method of producing the same are disclosed. The method includes inserting a first fibre element (304) in a crush resistant elongate tube element (302), wherein the first fibre element is suitable for monitoring at least one of strain, temperature and acoustic properties; inserting a further fibre element (306) in the tube element, wherein the further fibre element is suitable for curing a matrix material (308); and inserting a matrix material into the tube element to fill at least a length of the tube element such that the first and further fibres elements within that length are surrounded by matrix material.

Description

technical field [0001] The invention relates to an elongate element for a flexible pipe body and a method of producing the elongate element. In particular, but not exclusively, the invention relates to the monitoring of parameters such as strain, temperature and / or acoustics in flexible pipes. For example, these parameters can be monitored in the flexible pipe itself in the oil and gas industry. Background technique [0002] There are many technical fields in which it is useful to monitor one or more parameters associated with a structure from time to time or continuously. For example, sometimes bridges, road surfaces, ground areas, light poles, wind turbine blades, yacht masts, suspended power cables, etc. should be monitored repeatedly or continuously so that information identifying any potential problems with the structure can be identified and take remedial measures. [0003] Conventional flexible pipe is used to transport product fluids such as oil and / or gas and / or ...
