Embodiment Construction

[0033] In this specification, flexible pipes will be introduced. 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 end fitting in which a respective end of the pipe body terminates. figure 2 Illustrated is the manner in which the tubular body 100 is formed from a combination of layered materials forming a pressure-bearing conduit according to one embodiment of the invention. although figure 2 A number of specific layers are shown in , it being understood that the invention is broadly applicable to coaxial tubular body structures comprising two or more layers fabricated from a wide variety of possible materials. Note also that layer thicknesses are shown for illustration purposes only.

[0034] Such as figure 2 As shown, the tubular body includes an optional innermost carcass layer 101 . The carcass provides an interlocking structure that can act as an innermost layer, fully or partially preventing...

Abstract

A buoyancy element, riser assembly including a buoyancy element and a method of supporting a riser are disclosed. The buoyancy element (400) includes a body (402) of at least partly flexible structure having a volume that is adjustable between an expanded and contracted position, and an entry port (404) for fluid to be supplied to and / or removed from the body to thereby adjust the volume of the body.

Description

technical field [0001] The present invention relates to a buoyancy element, a riser assembly including the buoyancy element and a method of supporting a riser. In particular but not exclusively, the present invention relates to a riser assembly suitable for use in the oil and gas industry. Background technique [0002] Conventional flexible pipes are 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 (which may be a deep water location) to 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 a combination of layered materials forming a pressure-containing conduit. The tube structure allows for large deflections without creating bending stresses that impair the tube's functionality over its lifetime. The pipe body is generally constructed as a com...
