NWP 4-01.43.8 ALONGSIDE FUELING-AT-SEA RIGSFleet Underway Replenishment Guide (COMNAV-SURFPACINST 3180.2 or COMNAVSURFLANT-INST C9010.1) and NAVSEA S9571-A1-NBK-010,UNREP Station Capabilities Handbook, provide replenishmentstation data for selecting station and rig type.The preferred fuel transfer rig is fuel STREAM(tensioned spanwire). Fuel can also be transferred usingthe nontensioned spanwire rig, or as a backup, theclose-in rig (see Chapter 4). Fuel can also be transferredby the astern method (see Chapter 5).Fueling-at-sea hardware for delivery and receivingstations is listed in Figures 3-31 and 3-32 at the end ofthe chapter.3.9 FUEL STREAM RIGIn the STREAM rig for FAS (referred to as fuelSTREAM for brevity), the hose is supported betweentwo ships on the ram-tensioned spanwire (see Figure3-18). The fuel STREAM rig allows ships to open outto a greater distance than is possible with the otherfueling rigs, minimizes the possibility of tightliningand parting of the span wire, and provides for improvedpersonnel safety by maintaining constant tension inthe span wire.Normal operating air pressures of ram tensioners forfuel STREAM are generally 800 psi (5,516 kPa) air(8,000-lb (3,634 kg) line tension) for the single-hose rigand 1,550 psi (10,687 kPa) air (15,500-lb (7,041.6 kg)line tension) for the double-hose rig. See Figure 3-19for fuel STREAM ram tensioner air flask settings.NoteRamless spanwire winches, such as thoseused on aircraft carriers and battleships torefuel escorts and those installed in newerADs, use a hydraulic pressure compensatingsystem or electronic controls with a tensiontower instead of a ram tensioner to maintaintension on the spanwire.The fuel STREAM rig shall be rigged with wire forall saddle whips, including the retrieving saddle, wheneverwinches can be made available. Otherwise, doublebraidednylon line is substituted for one or more of thenormally wire-rigged saddle whips (see paragraph3.9.9). The use of a wire rope retrieving whip is mandatorywhen delivering a double-probe rig.Fuel STREAM rigs in order of preference are:1. Fuel STREAM with probe and carrier assembly2. Fuel STREAM with Robb or breakable-spoolcoupling.3.9.1 Rigging the Delivery Station for FuelSTREAM3.9.1.1 Hose Assembly. Hose lengths are joinedtogether by re-attachable couplings and clamps. Eachhose length shall have a male clamp coupling on theoutboard end and a female clamp coupling on the inboardend. The female end incorporates a rubber O-ringseal.When joining hose lengths, the male and femaleclamp ends are pushed into engagement. The joint isthen secured by a split clamp and band assembly whichis wrapped around each hose coupling and locked to retainboth couplings. It is important to protect the surfacesof the male clamp fitting to ensure a leak-proofseal when it is made up with the female coupling. Thesecouplings can be assembled and disassembled by fleetpersonnel. Before joining hose lengths, inspect eachlength per PMS procedures and replace damagedlengths. If usable portions of damaged hose sections aresalvaged and reused, hose sections must be hydrostaticallytested prior to placing them back in service.The fuel STREAM hose rig is approximately 300-feet(91.4 m) long with the following fittings and hose lengthscoupled in succession, starting with the inboard end.• Two 35-foot (10.6 m) lengths of hose (inboardlength cut to suit)• Flow-through saddle (No. 4)• Two 35-foot (10.6 m) lengths of hose• Flow-through saddle (No. 3)• Two 35-foot (10.6 m) lengths of hose• Flow-through saddle (No. 2)• Two 35-foot (10.6 m) lengths of hose• Flow-through saddle (No. 1)• One 22-foot (6.7 m) length of hose3-22 ORIGINAL
