NWP 4-01.43.10.7 2-1/2-Inch (63.5 mm) Hose Rig. The2-1/2-inch (63.5 mm) hose is normally rigged underthe single-hose fuel STREAM rig, as shown in Figure3-28, for transfer of small quantities of F76, F44, bulkPOL, or water. Once a hose has been used for one product,it must be dedicated to that product. The 2-1/2-inch(63.5 mm) hose can be sent as a close-in rig (see paragraph4.10) or supported on a synthetic line, called aspan line (see paragraph 4.11).3.11 DOUBLE-HOSE FUEL STREAM RIGThe double-hose fuel STREAM rig (Figure 3-29) isa tensioned spanwire rig with the span wire and saddlewhips tended by winches at the delivery station. Thetwo hoses are suspended from the span wire, one belowthe other or side by side, depending on the delivery station’shardware. The hose can be rigged with:1. Double probe to double-probe receivers (Figure3-7) or to a single-probe receiver2. A probe over a Robb coupling to a single-probereceiver and a Robb receiver (Figure 3-30)3. Two Robb couplings for fueling two Robb receivers.The span wire is passed to the receiving station bymessenger and the spanwire end fitting secured at thereceiving station. The span wire is tensioned by haulingin slack wire and compressing the ram tensioner. Thedouble-hose rig is hauled along the tensioned span wireto the receiving station. The receiving station hooks thefuel hoses to its fuel connections and the rig is ready forfuel transfer.Hardware for delivery and receiving stations is listedin Figures 3-31 and 3-32 at the end of the chapter.3.11.1 Fuel STREAM Station Rigging. FuelSTREAM station rigging varies slightly, depending onthe type of connection required at the fuel riser. Followthe rig hose construction guideline of paragraph3.9.1.1. Rig double probe to double-probe receivers asshown in Figure 3-7. Hose lengths (Figure 3-8), the 19inch (48.3 cm) centerline dimension (Figure 3-8), andthe adjustment of the stress wire bridle (Figure 3-9) arecritical for successful seating of double probes indouble-probe receivers.When a single-probe receiving station is rigged to receivea probe over a Robb coupling, rig as shown in Figure3-30; however, when sending a probe over a Robbcoupling to double-probe receivers, attach the messengerto the special inhaul clamp, as shown in Figure 3-10.NoteIf rigged for a double-probe delivery and aprobe-over-Robb delivery is desired, it ispermissible to remove the lower probe headand attach a 10-foot (3.0 m) section of hosewith Robb coupling. Lash the length of hoseto the side of the double-probe frame,similar to Figure 3-30, and send the rig to thereceiving station.Rig passing procedures for all double-hose rigs arebasically the same. The probes have automatic connectand disconnect features. All other couplings must bemanually connected and disconnected and require ariding line to retain the hose at the receiving station.3.11.2 Preparing Fuel STREAM With DoubleProbe(1) DELIVERY SHIP1. Fake out the STAR messenger and attach the inboardend to the messenger pip-pin on the trolleycarriage, as shown in Figure 3-7.Note• When sending double probe to double-probereceivers, use the STAR messenger withoutthe 60-foot (18.2 m) releasing line section(Figure 2-9). The remating line must be providedby the receiving station. Do not use thealternate spanwire end fitting (Figure 3-14b).• When sending double probe to a single receiver,use the STAR messenger and attach the5 inch (127.0 mm) soft eye to the upperpip-pin on the trolley carriage (Figure 3-30).Attach the messenger return line to the messengerreturn line pendant around the probetube (Figure 3-30). The 60-foot (18.2 m) releasingline section of the STAR messenger will beused by the receiving station as the remating line.2. Stop off the span wire to the messenger 350 feetfrom the inboard (shackled) end of the messenger,as shown in Figure 3-21.3. Fake out and attach the lead line for the stationphone line and the lead line messenger for thephone/distance line to the messenger (as required).4. Secure the 6 foot (1.8 m) tail of the station phoneline to a cleat at the bulwark.3-37 ORIGINAL
