Abstract
A closed-loop system for cleaning vessels containing drilling fluid residue. High pressure jets of water-based cleaning fluid are used to clean the interior of a vessel. The resulting slurry is sent to one or more solids/liquid separation stages to remove drill cuttings and other drilling fluid solids. The substantially solids-free cleaning fluid discharge is recycled.
