| 摘要 |
A system for maintaining production flow in a subsea pipeline having a proximate and a distal end, the pipeline being in fluid communication with a production facility on a distal end, the system comprising a flow loop comprising an inlet in fluid communication with at least one subsea well adapted to receive a hydrocarbon production flow, and an outlet in fluid communication with the proximate end of the pipeline; a pig launching system, adapted so that a pig may be selectively placed into the flow loop inlet; and a pig receiving system, adapted so that a pig may be removed from the hydrocarbon production flow from the flow loop outlet; wherein the flow loop has an inner surface roughness less than about 1000 micro-inches.
