A pipe assembly () includes a composite pipe () having a composite material formed of at least a matrix material and a plurality of reinforcing elements embedded within the matrix material. The pipe assembly () further comprises a metallic pipe stub () secured to an end region of the composite pipe () and configured to support a connector () to permit the pipe assembly () to be secured to separate infrastructure.

Composite pipe end connector

A tubular comprises a composite material including a matrix and a plurality of reinforcing elements embedded within the matrix. A method for heating the composite material of the tubular comprises exposing the composite material to a time-varying magnetic field to directly induce a flow of electrical current in the composite material. The method may comprise configuring the composite material so as to control the flow of electrical current and/or heat in the composite material. The method may be used for heating a composite fluid conduit for use in a subsea environment for the removal of the build-up of wax and/or hydrates on an inner surface of the fluid conduit. Additionally or alternatively, the method may be used for deforming a composite fluid conduit, or for joining a composite fluid conduit to a further component such as a further composite fluid conduit.

Heating method

A fluid conduit comprises a wall defining a fluid flow path and a confinement feature within the wall and being configured to confine energy within a cavity, wherein at least a portion of the fluid flow path extends through the cavity. The confinement feature may be configured to confine electromagnetic energy. The fluid conduit may comprise an oscillator defined by the cavity and a positive feedback arrangement. The fluid conduit may be configured for sensing a property of a fluid present in or flowing through the fluid conduit or for use in sensing a property of a fluid present in or flowing through the fluid conduit.

Fluid conduit

A pipe comprises a pipe wall formed of a composite material of a matrix and a plurality of reinforcing fibres embedded within the matrix, wherein the composite material in at least one region of the pipe wall is pre-stressed. The composite material in at least one region of the pipe wall comprises or defines at least one of a level of pre-tension and pre-compression.

Composite pipe

A riser system () comprises a riser () to be secured between a floating body () and a subsea location (). The riser comprises a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix. In use, the riser () comprises an upper portion () extending from the floating body () and having a region arranged to be in tension, a lower portion () extending from the subsea location () and having a region arranged to be in tension, and an intermediate portion () located between the upper and lower portions () and having a region arranged to be in compression. A flow-line jumper () configured to be secured between two subsea locations, a flow-line jumper arrangement comprising a flow-line jumper () and a method of forming a flow-line jumperare also disclosed.

Composite component deployment configurations

A fluid conduit () comprises a wall () defining a fluid flow path () and a confinement feature () within the wall () and being configured to confine energy within a cavity (), wherein at least a portion of the fluid flow path () extends through the cavity (). The confinement feature () may be configured to confine electromagnetic energy. The fluid conduit () may comprise an oscillator defined by the cavity () and a positive feedback arrangement (). The fluid conduit () may be configured for sensing a property of a fluid present in or flowing through the fluid conduit () or for use in sensing a property of a fluid present in or flowing through the fluid conduit (). More specifically, the present invention deals with a microwave cavity sensor wherein the cavity member () is embedded in the wall () of the fluid conduit (), the wall () including a composite region ().

A riser system configured to be secured between a surface vessel and a subsea location comprises a primary conduit and an auxiliary conduit extending adjacent the primary conduit, wherein the primary and auxiliary conduits are connected together at an axial location along the riser system via a connecting portion. The auxiliary conduit comprises a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix.

Riser system

A pipe comprises a pipe wall formed of a composite material of a matrix and a plurality of reinforcing fibers embedded within the matrix. At least one longitudinal portion of the pipe wall comprises or defines a local variation in construction to provide a variation in a property of the pipe.

A pipe comprises a pipe wall formed of a composite material of at a matrix and a plurality of reinforcing fibers embedded within the matrix, wherein at least one circumferential segment of the pipe wall comprises or defines a local variation in construction to provide a local variation in a property of the pipe.
