MEG STORAGE SYSTEM AND A METHOD FOR DEPLOYMENT AND OPERATION OF MEG STORAGE SYSTEM

摘要

The present invention a subsea storage of MEG in an immediate vicinity of a subsea production site, the system comprising a collapsible flexible bag and; - at least one charge conduit providing a MEG conduit path between a topside position and the collapsible flexible bag, - at least one discharge conduit providing a MEG conduit path between the collapsible flexible bag and the subsea production site. The collapsible flexible bag is arranged within an open mechanical structure, wherein the flexible bag when in use is forming a single barrier between MEG and ambient water and, wherein at least one booster pump is arranged on the discharge conduit for raising the MEG pressure to a level permitting injection of MEG into the production site and, wherein the at least one charge conduit has a conduit diameter of at least 50% smaller than the diameter of the at least one discharge conduit.
