NWP 4-01.4Figure 3-18. Fuel STREAM Rig — Single Hose with Probe• Flow-through riding line fitting• One 4-foot (1.2 m) length of hose• Flow-through riding line fitting• One 9-foot (2.7 m) length of hose• Fueling probe and carrier assembly.The 22-foot (6.7 m) outboard length may be cut tosuit when using the probe system to prevent probe damageat the delivery ship’s bulwark. When using doubleprobe, both hoses from the retriever saddle to the probetubes must be equal in length to permit seating of theprobes (see Figures 3-8 and 3-9).A stress wire connects each of the riding line fittingsand the retriever saddle (No. 1) to prevent the hose fromtaking a strain.4-foot (1.2 m) FAS hose sections are added on eachside of the flow-through saddles to extend the life of the35-foot (10.6 m) sections (see Figure 3-20).3.9.1.2 Hose End Fittings. The probe, which has a7-inch (177.8 mm) diameter, provides an improved rate offuel transfer over the Robb or NATO breakable-spoolcoupling, which has a 6-inch (152.4 mm) diameter. Robbor NATO breakable-spool and probe couplings may beexchanged on the same hose to meet customer requirements,but the Robb or NATO breakable-spool couplingshall be removed before the probe is attached to the hose.3.9.1.3 Rigging the Hose Assembly. The hose issuspended from the span wire by trolley blocks. Exceptfor the inboard saddle, one trolley is shackled toeach flow-through saddle and one trolley to each ridingline fitting. The trolley carriage is fitted to thespan wire.For passing the rig, the span wire is stopped to twobeckets, 350 feet (106.5 m) from the shackle end of themessenger, as shown in Figure 3-21. Grease in the wayof the stops should be removed from the span wire.3.9.1.4 Saddle Whips. Wire rope saddle whips areused to control the positions of the flow-through saddleson the span wire (see Figure 3-18).3.9.1.4.1 No 3. Saddle Whip. This whip controlsboth the No. 3 and No. 4 saddles. The whip end is securedto the No. 3 saddle, reeved through the three blocks supportingthe No. 4 saddle, and then fairled to the No. 3saddle winch. The runner block (normally called a yo-yoblock), attached to the No. 4 saddle, is a block equippedwith an antitoppling device (Figure 3-22). One end of a3/4 inch (19.0 mm) wire preventer is shackled to the bottomof the No. 4 saddle and the other end of the preventeris shackled to a designated preventer padeye. Thepreventer is sized to suit the individual ship’s installationto prevent two-blocking the No. 4 saddle.3.9.1.4.2 No. 2 Saddle Whip. The whip end is securedto the No. 2 saddle, reeved through a block on thekingpost outrigger, and then reeved through a fairleadblock to a winch.3-23 CHANGE 1
