Direct electrical-heating cables
- Direct Electrical Heating (DEH) systems supply current to the production line at the sea bed and heat up the pipeline in order to prevent formation of hydrates. Thus avoiding reduced flow or full stop in the fluid transportation.
- The system was developed through a partnership of Statoil, Nexans and other suppliers. Nexans is the only supplier so far to have these systems in operation.
Nexans completed the first offshore electrical pipeline heating system for Statoil in the Åsgard field (North Sea) in 2000. We also provided a pipeline heating system for the Huldra, Kristin and Nome fields, and Statoil’s Tyrihans and Alve fields.
