Neptune Energy has installed and tested the world’s longest trace-heated subsea production pipeline at its operated Fenja field in the Norwegian Sea.
TEMPERATURE
The company said that the 37km electrically trace-heated (ETH) pipe-in-pipe solution would transport oil from the field to the Njord A platform, operated by Equinor.
It will also significantly reduced the potential cost of the development by enabling the field to be tied back to existing infrastructure.
Due to the high wax content of the Fenja field’s oil, the contents of the pipeline must be warmed to a temperature above 28-degrees Celsius before starting the flow after a scheduled shut down or interruption.
During normal production, the temperature in the pipeline would be well above this temperature.
The ETH pipeline was developed and qualified through a collaborative approach with TechnipFMC.

Neptune Energy is an independent global exploration and production company with operations across the North Sea, North Africa and Asia Pacific.
The business had production of 142,000 net barrels of oil equivalent per day during 2020 and 2P reserves at 31 December 2020 of 601 million barrels of oil equivalent.
