ABSTRACT:
A system for cleaning vessels that have been contaminated with oil field drilling and production waste materials such as oil well drilling fluid or hazardous waste using recycled wash water. As dirty wash water accumulates in a vessel during cleaning, it is transferred to a settlement section of the waste receiving barge. A cationic polymer is injected into the suction side of a waste water pump during transfer of dirty fluid from the vessel to the receiving barge. The polymers react with fluids to begin an initial settling process within the waste receiving barge. Decant water is subjected to secondary settlement and secondary chemical treatment after it leaves the primary settling section of the waste receiving barge. The laundered water is returned to the wash water storage facility for reusing and cleaning the same vessel or additional vessels. In this fashion, waste is continuously concentrated in the receiving vessel for ultimate disposal at a remote site and wash water is recycled for reuse.
