PRODUCTION RISER WITH A GAS LIFT FACILITY |
摘要 |
A subsea riser system with a gas-lift facility has a production riser having a riser conduit and at least one lift gas injection port communicating with the riser conduit. An umbilical is arranged to supply lift gas to the lift gas injection port. A heating unit is positioned to act on a downstream end region of the umbilical adjacent to the lift gas injection port. A method of providing lift gas to a subsea riser system includes the steps of conveying lift gas toward a production riser and, before injecting the lift gas into the production riser, heating the lift gas locally adjacent to the production riser. |
