U.S. Navy surface combatants use pre-filters and filter separators in the fuel oil service system to filter out sediment and water in order to meet the fuel oil cleanliness requirements to operate the gas turbine engines and generators. The ships have reported high usage rates of the pre-filters necessitating the replacement of the pre-filter elements. High replacement rates of the elements obviously increases the burden on ships force but it also increases the operating costs due to the cost of the replacement elements and the storage, handling and disposal of the hazardous material generated. One of the causes of the poor quality fuel oil is the purifier’s inability to remove all sediment and water from the fuel oil when transferring fuel from storage to service. A prototype two-stage self-cleaning cross flow filtration unit was installed in parallel with a fuel oil purifier on a surface combatant. This unit was operated during a deployment cycle and had a through put in excess of one million gallons of fuel. The purpose of this paper is to discuss the background leading to the design of the unit, the installation, operation, data, results and future design changes.
