Install Aircraft Refueling System
Client: NAVFAC Southeast
Location: Naval Station Mayport, FL
This project called for installation of an aircraft (helicopter) direct fueling system (design by U.S. Navy) to replace the existing system of using tactical refueler trucks on the aircraft parking apron for helicopter refueling. The direct fueling system is based on a pressurized, recirculating fueling system, including fuel return piping from the single aircraft direct fueling station (pantograph) location to two operating tanks. Two existing 15,000-gallon JP5 aboveground storage tanks were modified to support the new system. Refueling control valves, fueling station meter, fueling station venturi, swivel joints, fueling hose, pressure gauges, fittings, and pantograph sections were installed to encompass the complete system. Fueling pumps and filters / separators were installed near the existing fuel storage tanks. Underground fuel lines were installed under the aircraft parking apron in an underground casement pipe. All underground piping was installed by horizontal directional drilling methods without disturbance of the active aircraft apron.
