NAVY DEVELOPEMENT OF SUITABLE SHIPBOARD OIL/WATER SEPARATORS

The evolutionary development and evaluation of a suitable Navy shipboard bilge oil--water separator is detailed. Shipboard screening tests revealed significant problems caused by particulates and detergents in the bilge fluids. Although effluent goals could be met, severe penalties in terms of costs of process, logistics support, and size of separation equipment were evident. Screening tests produced 3 promising systems for formal technical evaluation. In-port and at-sea performance tests, bulk oil removal, oily waste holding tank and detergent-contaminated waste processing demonstrations, and reliability and maintainability assessments were included in the technical evaluation. Performance goals were established for effluent oil levels during in-port and at-sea periods, water content of separated oil, average element set life, cost to process, mechanical-electrical reliability, and mean time to repair. The parallel-plate separator was selected for operational evaluation and modified to improve its structural adequacy and machinery-personnel interface. The operational evaluation was structured to determine whether the unit could be operated and maintained by ship's personnel while processing both actual and deliberately contaminated bilge water on a daily basis for 6 mo.
