Eighty U.S. Coast Guard cutters with Oily Water Separator Systems installed were surveyed. These cutters range in size from 65 foot river buoy tenders to 378 foot high endurance cutters. Filter-coalescer cartridge usage rate and cost data was obtained. Commencing with the installation of the first prototype oily water separator in September 1973, approximately 10,283,260 gallons of effluent have been processed, at a cost of 33,967.73 for cartridges. Installation costs for these systems totalled 1.368 million. Overall cost gallon of effluent processed to date is 0.3497 cents 100 GPM OWS cost is 0.2371 centsgallon 10 GPM OWS cost is 0.7537 centsgallon and the 5 GPM OWS cost is 1.2378 centsgallon. These figures represent only the cost of cartridges and do not reflect maintenance, installation or repair costs to the OWS systems. Projected installation costs for all 261 active U. S. Coast Guard vessels is 3. 5 million, and the projected annual cartridge cost for operating the 261 systems is 156,129. Based on present cartridge prices and available data. The projected annual cartridge cost to equipment the 125 confirmed OWS systems for the coming year is 69,085.00.
