The Ærfugl field is a gas condensate field located in the Norwegian Sea. Heat input into the flowline system is required during shutdown and potentially also during off-plateau production periods. A new enabling technology known as electrically heat-traced flowline (EHTF) will be used to enable system startup and shutdown and to maintain production fluids outside of the hydrate envelope during steady-state operation.
Background
EHTF is a pipe-in-pipe (PIP) system in which heating cables are used to heat the inner pipe. This enables even longer tiebacks and development of fields with challenging hydrate characteristics.
