Abstract
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.
