A method for forming a composite fluid conduit includes providing an inner pipe having a variation in cross-section between at least two different longitudinal sections thereof and applying a fiber reinforced composite material to the inner pipe. In some disclosed examples the variation in cross section may be provided intermediate opposing ends of the inner pipe. In other disclosed examples the variation in cross section may be provided at an end region of the inner pipe.

A riser system with a primary conduit extends between a surface vessel and a subsea location and an auxiliary conduit that extends adjacent the primary conduit. In one example a composite jumper conduit extends from the surface vessel and is fluidly connected to the auxiliary conduit. The jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix. In one example a subsea composite jumper conduit extends from subsea infrastructure and is fluidly connected to the auxiliary conduit. The subsea jumper conduit includes a composite material formed of at least a matrix and one or more reinforcing elements embedded within the matrix.

A fluid sensor comprises a base pipe 320 defining a fluid flow path and a cavity member 330. The cavity member 330 comprises an electrically-conductive composite material including a matrix and one or more reinforcing elements like carbon fibres 374 embedded within the matrix. In one embodiment the carbon fibres 374 in the main body portion 330a of the cavity member 330 are wound along a left-handed helical path at an angle of approximately 80 degrees relative to the longitudinal axis 376 and along a right-handed helical path at an angle of approximately 45 degrees relative to the longitudinal axis 376. Such an arrangement of carbon fibres may permit omni-directional current flow in the main body portion 330a, which thus supports the same modes that would be supported by a metallic cavity member of the same geometry.

A riser system (202) comprises a riser (204) to be secured between a floating body (206) and a subsea location (209). 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 (204) comprises an upper portion (214) extending from the floating body (206) and having a region arranged to be in tension, a lower portion (216) extending from the subsea location (209) and having a region arranged to be in tension, and an intermediate portion (218) located between the upper and lower portions (214, 216) and having a region arranged to be in compression. A flow-line jumper (302, 402) configured to be secured between two subsea locations, a flow-line jumper arrangement comprising a flow-line jumper (302, 402) and a method of forming a flow-line jumper 302, 402 are also disclosed.
