Abstract
Direct Electrical Heating (DEH) of offshore pipelines is an established
cost-efficient and environmental friendly method for flow assurance in
offshore oil production compared to traditional methods such as
chemical injection. The first DEH system was installed in year 2000 in
the North Sea, and is presently designed for around 5 years of usage
during the lifetime of the field.
In order to increase the attractiveness of the DEH technology an
innovative step by higher power frequency and optimized pipe coating
methods is utilized. The main drivers for this next generation DEH are
continuous usage, applicable to ultra-deep waters and marginal fields as
well as reduced costs and weight.
