In order to avoid comprehensive verification issues it is proposed to design the electrical heating system as a sectioned heating system. I.e. the pipeline will be heated from a power supply system feeding a number of sections. The sections can be fed by separate power cables to each section or each section can be galvanically separated by a subsea transformer and fed from a common power cable. If the first section is powered from shore, which may be the case for Arctic regions, an alternative heating system to DEH can be selected to avoid problems related to grounding and stray currents. Alternatives such as induction heating (IHS) and pipe in pipe (PiP) heating systems are considered. For Arctic regions the landfall part may need special measure for protection against icebergs.
