NWP 4-01.44.11 NONTENSIONED SPANLINE FUEL RIGThe 2-1/2-inch (63.5 mm) fuel hose, supported on anontensioned synthetic line, as shown in Figure 4-5,may be employed whenever conditions on either thedelivery or receiving ship preclude transfer of F76,F44, or water using the 2-1/2-inch (63.5 mm) hose rigwith the probe fueling system.The spanline fuel rig is 188 feet (57.3 m) long andconsists of four 35-foot (10.6 m) hose assemblies andone 23-foot (7.0 m), one 15-foot (4.6 m), and one10-foot (3.0 m) hose assembly. Additional lengths ofhose may be used as jumpers and added to the rig toreach some riser locations on either ship; however, noother change is authorized for this rig. The hose is suspendedfrom four spanline trolleys. Most of the componentsin the spanline fuel rig are identical to likecomponents in the other 2-1/2-inch (63.5 mm) fuel rigs.Hardware for delivery and receiving stations is listedin Figures 4-11 and 4-12 at the end of the chapter.4.11.1 Rigging the Nontensioned Spanline FuelRig. At every assembly step of the following stepby-stepprocedures for rigging the spanline fuel rig, ensurethat components that contact F76 or F44 are notused in a potable water rig.CAUTIONOnce a hose rig has been used for oneproduct, hose rig components that contactthe product must be dedicated to thatproduct only. See Appendix L for transfer ofpotable water.The following procedure defines the necessary stepsfor rigging the 2-1/2-inch (63.5 mm) hose for use with aspan line.1. At the delivery station, lay out enough 35-foot(10.7 m) hose assemblies of 2-1/2-inch (63.5mm) hose to suit station arrangement and riserlocation.2. Couple the two hose assemblies together with asplit clamp.3. Using a reducer, an adapter, and split clamps asrequired, attach the female end of the 2-1/2-inch(63.5 mm) hose to the ship’s riser.4. Couple the male end of the outboard 35-foot(10.7 m) hose section to the 2-1/2-inch (63.5mm) flow-through saddle fitting.5. Couple the female end of another 35-foot (10.7m) hose assembly to the other end of the saddle.6. Using the shackles and link, attach the flowthroughsaddle to spanline trolley No. 4, asshown in Figure 4-6. Fake down hose sectionsand lay the trolley on the deck.7. Couple a flow-through saddle to the 35-foot(10.7 m) hose assembly running from the saddleattached to trolley No. 4. Attach this saddle totrolley No. 3 in the same manner that the saddlewas attached to trolley No. 4. The rigging isshown in Figure 4-7.8. Couple a flow-through saddle to the 35-foot(10.7 m) hose assembly running from the saddleattached to trolley No. 3. Attach this saddle totrolley No. 2 in the same manner that the saddlewas attached to trolley No. 3. See Figure 4-7.9. Couple a 23-foot (7.0 m) hose assembly to theflow-through saddle attached to trolley No. 2.10. Couple a flow-through saddle to the 23-foot(7.0 m) hose assembly and attach this saddle totrolley No. 1. See Figure 4-8.11. Couple a 15-foot (4.6 m) hose assembly to theflow-through saddle attached to trolley No. 1.12. On the male end of the hose, install in sequencean automatic coupling and a 90-degree elbowadapter.13. Couple a 10-foot (3. 0 m) assembly of 2-1/2-inch(63.5 mm) jumper hose to the 90-degree elbowadapter. Attach the D-2 nozzle onto the male endof the jumper hose.14. Cover the D-2 nozzle with the attached cap andinstall a shackle on the 90-degree elbow adapteras shown in Figure 4-8.15. Fold the jumper hose and secure it to the23-foot (7.0 m) hose assembly aft of the saddle.See Figure 4-8.16. Shackle the 800-foot (243.8 m) STAR messengerand the messenger return line to trolley No. 1.4-11 ORIGINAL
