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

NWP 4-01.45.8.4.3.2 Rudder Required. To maintain coursewhen a ship is alongside, it is usually necessary to continuouslycarry a small amount of rudder. The amountdepends on the size of both ships, their loads, sea andwind conditions, refueling speed, and the distance betweenships. As cargo is transferred and the trim of theship changes, the amount of rudder required to maintaina steady course will change.5.8.5 Alongside Replenishment Procedures.Since tankers cannot pass an alongside fueling rig to receivingships, they are limited to refueling fleet units thatcan pass the spanwire rig or fuel STREAM rig to them.Information about these rigs is provided in Chapters 3and 4. To apply this information to refueling by tankers,substitute the word “tanker” for “receiving ship” and theword “oiler” or words “fleet unit” for “delivery ship.”5.8.5.1 Tanker Spanwire Refueling5.8.5.1.1 Tanker Hose. Tankers have 6-inch (152.4mm) or 8-inch (203.2 mm) hoses with the necessary reducers.Minimum hose allowance per ship is 140 feet(42.6 m) in 10 foot (3.0 m) and 20 foot (6.0 m) lengths.When practicable, a length of hose is used to make aflexible extension to the cargo manifold, thus facilitatinghook-up to the fleet unit’s gear. The extra hose lengths arespares and are used for inport loading and discharging.5.8.5.1.2 Use of Quick-Release Couplings byTankers. A 6-inch (152.4 mm) breakable-spool quickrelease(NATO) coupling and/or a combined quickreleasecoupling and valve (Robb coupling) are used inrefueling. (See Figures 3-11 and 3-12.) Masters of tankersshould ensure that crew members stationed at refuelingstations know how to use these couplings. If tanker personnelrequire practical instruction on using the Robbcoupling, a request may be made to the fleet unit to sendover Navy personnel to instruct the tanker crew.5.8.5.1.3 Breakable-Spool Quick-ReleaseCoupling. All tankers are supplied with both theA-end and the B-end of this coupling. Tankers normallyhave the A-end installed on the cargo manifold orthe hose extension to the manifold. The fleet unit sendsover the hose fitted with the B-end of the coupling.5.8.5.1.4 Robb Coupling. Some tankers may besupplied with the male end of the Robb coupling. Likethe A-end of the breakable-spool coupling, it is installedon the manifold or the hose extension, ready forconnection to the female end that comes over with thehose from the fleet unit. Care should be taken to avoiddropping and damaging the Robb coupling; particularcare is required when the pelican hook is released.5.8.5.1.5 Breakable-Spool and Robb CouplingCombined. This combination is recommended for useto allow disconnect in the event of an emergency, as theRobb coupling will not disconnect when under a strain. TheA-end and B-end of the breakable-spool coupling arebolted together, and the coupling is fitted to the tanker’sfuel manifold. The male end of the Robb coupling is attachedto the outboard end of the breakable-spool coupling.5.8.5.1.6 Fleet Unit Procedures. The fleet unit suppliesthe rig and passes all lines (including the phone/distance line) to the tanker. Because of the shortage ofmanpower on the tanker, only one rig should be passedat a time. The fleet unit tends all lines.As the fleet unit comes alongside, it passes a shotline to the tanker by means of a line-throwing gun orbolo. The shot line is attached to the STAR messenger(see Figure 2-9 and paragraph 2.3.5). The phone/distanceline, station phone line, and span wire are attachedto the messenger.5.8.5.1.7 Passing the Rig. As the fleet unit passesthe lines and the rig, the tanker receives them usingthese procedures:1. Hauls in the shot line and the first messenger.2. Secures the phone/distance line with the zeroflag at the rail or on a stanchion directly belowthe navigation bridge.3. Hooks up the telephone.4. Continues to haul in until the rig messenger comesaboard, places the end of the messenger into a 12inch (30.5 cm) snatch block below the padeye forthe span wire, and leads the end to a winch.5. Continues to haul in on the messenger until thepelican hook on the span wire comes aboard.6. Secures the pelican hook to the padeye on the tripodor kingpost and detaches the messengerfrom the span wire. (The fleet unit takes up slackin the span wire.)7. Resumes heaving in on the messenger to bringthe hose on board.8. Pulls the hose in until a bight (not an eye) of oneriding line can be slipped over the riding line hook.9. Cuts the stops that secure the hose to themessenger.5-35 ORIGINAL
