Problems solved by technology

However, this method involves additional and complex fabrication steps which can be complex processes involving careful alignment, heating steps and cooling steps during fabrication
Also it is difficult to control geometrical tolerances during the extrusion process and this method can initiate a chain reaction to subsequent layers formed radially outside such an extruded layer
[0017] With the tape or extruded layer technology mentioned above, the materials used until now have limited the available thermal conductivity (k) values
[0018] Also, insulating materials used to date have limited thermal storage capacity and have not proven capable of preventing solidification of wax, hydrate, etc.

Embodiment Construction

[0080] Throughout this document, reference will be made to flexible pipes. It is to 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 The manner in which the tubular body 100 is shown to be formed from a composite of layered materials forming a pressure-containing conduit according to an embodiment of the invention is shown. although figure 1 A number of specific layers are shown in , it being understood that the invention is broadly applicable to composite pipe body structures comprising two or more layers fabricated from a wide variety of possible materials. Note also that layer thicknesses are shown for illustrative purposes only.

[0081] Such as figure 1As shown, the tubular body includes an optional innermost carcass layer 101 . The carcass provides an interlocking construction that can act as an innermost layer, fully or partially preventi...

Abstract

A device and method for maintaining the temperature of a subsea installation, in particular a fluid in a device (100). Materials with high latent heat for phase transition are used to release latent heat to the fluid as the fluid temperature decreases towards a threshold.

Description

technical field [0001] The present invention relates to a method and apparatus for providing one or more layers of thermally active material in or on a pipe, more particularly a flexible pipe. In particular, but not exclusively, the present invention relates to the use of one or more encapsulated or encapsulated regions of thermally active material, wherein the thermally active material is effective to absorb thermal energy under a first set of conditions and to absorb thermal energy under a second set of conditions. Materials that release heat energy under two sets of conditions. The thermally active material is disposed in one or more layers of the flexible pipe body. A thermally active material is, in a particular embodiment, a material with a high latent heat for phase transition. Suitable materials are also known as phase change materials (PCMs). In the present invention, the thermally active material acts as a thermal energy storage accumulator for either absorbing he...
