CRITERIA FOR ACCEPTANCE OR REJECTION OF JP-5

All ships fitted with two or more downcomers can use any or all to expedite the refueling operation. The number of tanks that can be opened and the method of receiving will vary on the individual ships, depending on the number of personnel available as manifold operators, sounding teams, etc., and the experience gained after several refueling operations. NOTE An adequate number of contamination tanks must remain empty to receive the recirculated fuel from Cla-Val stations. When the last port and starboard tanks to be filled reach 80 percent capacity, notify the tanker to reduce pumping. Top off the last tanks. When the overflow tanks reach 95 percent capacity, order the tanker to stop pumping. After the tanker has ceased pumping, close the filling connection gate valve on the sponson. At the completion of the replenishing operation, notify the officer of the deck of the start and stop pumping time and record the total gallons received. This information is entered in the ship’s log. Secure and restow all equipment. Close all valves in the filling and transfer system. The tanks should be sounded to obtain an accurate account of all JP-5 on board. During the final soundings, compare readings with the tank level indicators and adjust as necessary. CRITERIA FOR ACCEPTANCE OR REJECTION OF JP-5.—The standards of fuel cleanness (table 4-4) are established as maximum limits for transfer of aviation fuels between shore activities and ships. Normally, contamination levels are maintained substantially below these levels. Samples are taken continuously from the filling connection at the initial start of pumping until a clear sample is obtained. Thereafter, samples are taken every 15 minutes during the refueling operation. Any time a sample exceeds the contamination limits listed in table 4-4, the pumping operation must cease. The final decision of acceptance or rejection of the fuel rests on the commanding officer. EMERGENCY BREAKAWAY.—During a refueling at-sea operation, any number of unforeseen circumstances could occur, making an emergency Table 4-4.—Standards of Fuel Cleanness 4-66
