Document Type and Number:
WIPO Patent Application WO2005042905
Kind Code:
A3
Abstract:
This invention relates to a flowline-riser production system for the recovery of hydrocarbons from offshore wells, and a method for pigging the interior surfaces of the riser and flowlines. More particularly, this invention is a piggable flowline-riser system in which a pig is launched from or near a host production facility, down a riser into a looped flowline and returned up through the same riser. According to one embodiment of the invention, there is a piggable flowline-riser system for producing hydrocarbons comprising a riser, a "Y" joint and a looped flowline, wherein the looped flowline is in fluid communication with at least one subsea well.
