UNDERWAY REPLENISHMENT NWP 4-01.4 - Historic Naval Ships ...

NWP 4-01.4by a split clamp and band assembly that is wrappedaround each hose coupling and locked to retain bothcouplings. It is important to protect the surfaces of themale clamp fitting to ensure a leak-proof seal when it ismade up with the female coupling. These couplings canbe assembled and disassembled by fleet personnel. Beforejoining hose lengths, inspect each length per PMSprocedures and replace damaged lengths.The auxiliary hose rig is templated to fit under thesupporting 7-inch (177.8 mm) hose rig and must thereforebe constructed in accordance with paragraphs3.9.1 or 4.9.1 up to the outboard riding line fitting. Tothe outboard end of the outboard riding line fitting connectthe pigtail assembly as follows: One 15-foot (4.6 m) length of hose. Autotension disconnect. Adapter elbow, 90 degree. One 10-foot (3 m) length of hose. D-2 nozzle for fuel transfer.Hose sections, each 4 feet (1.2 m) in length, shall beadded to appropriate saddles to match the configurationof the supporting 7-inch (177.8 mm) hose rig asapplicable.4.12.2 Rigging the Hose Assembly. The auxiliaryhose rig is suspended from the supporting 7-inch(177.8 mm) hose rig at the hose saddle points using two3/4-inch (19.0 mm) safety anchor shackles and a1/2-inch (13.0 mm) link. The hose pigtail shall bedressed per Figure 3-28.4.12.3 Preparing the Auxiliary Hose Rig1. The delivery and receiving ship preparations are inaccordance with paragraphs 3.10.2, 3.11.2, or 4.9.2.2. Also, on the receiving ship, connect a pendantassembly to a bulkhead padeye as close as possibleto station centerline. The pendant is fabricatedusing 1-1/8-inch (28.5 mm) circumferencenylon (MIL-R-17343) with 3/8-inch (9.5 mm)diameter oval thimbles (FF-T-276, Type II) oneach end, length to suit the station. Shackle oneend to the bulkhead padeye with a 3/4-inch (19.0mm) safety anchor shackle. The other end isconnected to the 1/2-inch (13.0 mm) specialshackle on the 90-degree elbow adapter with a3/4-inch (19.0 mm) screw pin shackle.4.12.4 Passing the Auxiliary Hose Rig1. Passing procedure is the same as for probe (seeparagraph 3.10.3), double probe (see paragraph3.11.3), or nontensioned (see paragraph 4.9.3)for delivery and receiving ships.2. Also, on the receiving ship, cut the hose pigtailstops after the 7-inch (177.8 mm) hose is connected.3. Disconnect the 90-degree elbow adapter fromthe probe carriage and connect it to the pendantassembly (see Figure 4-10). Dress the outboardhose from the auto disconnect coupling clear ofany obstruction on the deck or bulwark.4. Remove receiver adapter cover, if applicable,and connect the hose pigtail.5. Open the valve on the D-2 nozzle.4.12.5 Operating the Auxiliary Hose Rig. Operationof the rig is the same as in paragraph 3.10.4, 3.11.4,or 4.9.4 for delivery and receiving ships.4.12.6 Retrieving the Auxiliary Hose Rig(1) DELIVERY SHIP1. Stop pumping.2. Complete the blowdown/back suction and secureall valves. (See paragraph 3.9.1.6.)(2) BOTH SHIPSSignalmen signal “Replenishment completed at thisstation. Commence unrigging.”(3) RECEIVING SHIP1. Close the fuel valve on the D-2 nozzle. Disconnectthe hose from the riser and cap connectionhalves as appropriate.2. Disconnect the 90-degree elbow adapter fromthe pendant and secure it onto the deliverycarriage.3. Secure the hose pigtail to the 7-inch (177.8 mm)hose rig as shown in Figure 3-28.4. Follow the procedure outlined in paragraph3.10.5, 3.11.5, or 4.9.5 as applicable.4-19 ORIGINAL
