Subsea hydrocarbon flowline system and related method and use

A subsea hydrocarbon flowline system (300) is disclosed. The flowline system has a hydrocarbon flowline (302); an electric trace heating system (304) arranged along at least a part-length of the flowline to control the temperature of hydrocarbon fluid flowing in the flowline; and a power input conne...

Zusammenfassung:	A subsea hydrocarbon flowline system (300) is disclosed. The flowline system has a hydrocarbon flowline (302); an electric trace heating system (304) arranged along at least a part-length of the flowline to control the temperature of hydrocarbon fluid flowing in the flowline; and a power input connector (Pin) configured for receiving electrical power from an electrical power providing system for powering the electric trace heating system. The electric trace heating system has a first three-phase trace heating cable (C') and a second three-phase trace heating cable (C''), each trace heating cable extending between the power input connector and a cable termination (T'; T'') where phase conduits (L1', L2', L3'; L1'', L2'', L3'') of the trace heating cable are Y-connected and terminate in a neutral connection point (L
