Abstract: A fluid conduit assembly that includes a fluid conduit comprising a tubular member extending between at least a first end and a second end is disclosed. The tubular member has an inner surface configured to convey a fluid and an outer surface. A heater trace is deposited on the outer surface of the fluid conduit and configured, in use, to heat the fluid within the inner surface of the fluid conduit. An insulation shell is located over the heater trace and configured to suppress heat losses from the fluid conduit. An interconnect device is located proximate to each of the first end and the second end on the fluid conduit. A portion of the interconnect device extends through the insulation shell to electrically connect the heater trace to one or more external devices. Fluid transport systems including the fluid conduit assembly are also disclosed.

Abstract: An electric heating system (16) for a subsea pipeline (10) comprises heating sections (16A, 16B) disposed in neighbouring longitudinal succession. A switchboard (26) is configured to supply power in a cycle alternating between the sections. Levels of heating power supplied to the sections are in mutually-opposed alternation throughout that cycle. During the cycle, a greater level of heating power is supplied to a first section (16A) than to a second section (16B) for a period of time. Conversely, a greater level of heating power is supplied to the second section (16B) than to the first section (16A) before and after that period. For example, the second section may be deactivated during that period and the first section may be deactivated outside that period. By applying heat in this intermittent or fluctuating manner, the overall power requirement of the system is greatly reduced. There is a corresponding reduction in the size, complexity and cost of power generation and transmission hardware.

Abstract: A riser heating system arranged for heating a hydrocarbon-conducting riser (1) that comprises a riser steel pipe (2) and that extends from a surface structure (5) towards the seabed (3). The system comprises an electric power supply (13) comprising a first output line (15a) and a second output line (15b), a first riser cable (17n, 17a) connected to the first output line (15a) and a second riser cable (17b) connected to the second output line (15b). The first and second riser cables (17n, 17a, 17b) extend along the riser steel pipe (2). The power supply (13) is configured to supply electric alternating currents in the first and second riser cables (17n, 17a, 17b), thereby inducing heat in the riser steel pipe (2).
