A riser (112,114) comprises a plurality of conduits (200) extending from the seabed towards the surface and having an upper end supported at a depth below the sea surface. At least some of the conduits (200) are arranged around a structural core (410). The conduits comprise an insulated production line (200), an uninsulated service line (500) providing a pigging loop with the insulated production line, and a water injection line (210).
