Abstract : This report presents the results of testing two candidate Oil/Water Separator (OWS) units. The tests were planned and directed by the Naval Facilities Engineering Service Center (NFESC) at Port Hueneme, California, under joint sponsorship and funding from the United States Coast Guard Research and Development Center and the Marine Spill Response Corporation. The 'Intr-Septor 250' was a repeat performer, having been modified as a result of similar tests conducted by the Navy in 1992. The second candidate, the FRAMO 'Skimmer Separator,' arrived as a prototype machine, having recently been assembled and put through shakedown tests by the manufacturer. Each unit was subjected to a comprehensive sequence of tests that included the processing of various percentages of test oil in water and oil/water emulsion in free water (with and without emulsion breaker). In addition, tests that included the passage of entrained debris were completed to establish a baseline for performance under conditions conducive to clogging the OWS. In summary, although each machine was successful in effectively separating oil from water at particular inlet conditions, each recorded operational 'hiccups' while performing over the full range of input characteristics that would be anticipated during an actual marine spill. The most significant deficiency was the inability to operate effectively and reliably through wide variations in percentage of waste oil and emulsion composition, and to handle ingested debris materials. In particular, the processing of heavy emulsions and slugs of particle debris appears to 'gum up' the inner workings to such a degree that partial disassembly and cleaning of small orifices was required in order to get the OWS back on line. A recommended next step in evolution is to bypass the limitations of performance inherent in machines of this size and power by improving th
