Abstract
An electric heating system for a subsea pipeline comprises heating sections disposed in neighbouring longitudinal succession. A switchboard 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 than to a second section for a period of time. Conversely, a greater level of heating power is supplied to the second section than to the first section 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.
