摘要： A system (2) for offshore hydrocarbon processing comprises a host (6) at surface level, a subsea processing plant (4), and an umbilical (8) connecting the host and the subsea processing plant. The subsea processing plant is adapted to receive a multi-phase hydrocarbon stream (10) from a wellhead and to output at least a hydrocarbon gas-phase stream (14) satisfying a rich gas pipeline transportation specification to a pipeline. The umbilical provides a desiccant (12) for drying the hydrocarbon gas, as well as power and control (12), from the host to the subsea processing plant.
