NWP 4-01.4CHAPTER 3Liquid Cargo Transfer — STREAMRigging and Operation3.1 SCOPEFleet units at sea are supplied with fuel by means ofhoses suspended between ships. During fuel transfer,lubricating oil (in drums), industrial gases (in bottles),water, personnel, and cargo may also be transferred.This chapter and Chapter 4 detail the procedures fortransferring fuel between ships of the U.S. Navy — bySTREAM and non-STREAM methods respectively;while Chapter 5 covers the procedures employed whenMSC tankers are used for underway replenishment ofNavy oilers and aircraft carriers. ATP 16 covers proceduresemployed when conducting FAS operations withships of NATO nations.3.2 DELIVERY SHIP CHARACTERISTICSThe largest volume of fuel is transferred by fleet oilersduring regularly scheduled replenishments. However,major combatants, CLF ships (AE/T-AFS), andamphibious ships frequently refuel other ships, especiallytheir screening ships.3.2.1 Speed. Fleet oilers normally are limited tospeeds of 12 to 16 knots when transferring fuel. Fastcombat support ships and major combatants can transferfuel at higher speeds when weather and sea conditionspermit.3.2.2 Liquid Conversion Tables. The Fleet OilerManual (Tables 5 and 7 of Appendix H) should be consultedfor accurate and detailed liquid cargo planning.3.2.3 Hose Sizes and Pumping Rates. Figure3-1 gives the hose sizes and pumping rates of varioustypes of ships when transferring F76 and F44.3.3 TRANSFER STATIONS3.3.1 Oiler Stations. Fleet oilers can rig up to sevenseparate transfer stations to deliver petroleum products.Figure 3-2 shows the location of typical stations on variousclasses of oilers and the products available at eachstation. The UNREP Station Capabilities Handbook,NAVSEA S9571-A1-HBK-010, shows station locationson all delivery and various receiving ship classesand a listing of products for each station.Oilers usually are rigged for fueling large ships (includingCGs) to port and small ships to starboard. Ifnecessary, however, oilers can transfer fuel to any shipfrom either side, except CVs, LHAs, LHDs, and LPHs,which are always fueled to port.3.3.2 Non-Oiler Stations. Carriers and amphibiousand auxiliary ships that often transfer fuel to other ships(generally smaller) are normally rigged as follows:1. Carriers — Two or more starboard stations2. Amphibious and auxiliary ships — One or morestations, port or starboard.3. Selected Maritime Preposition Ships (MPS) —One astern fueling rig.3.4 STANDARD HOSE RIGS3.4.1 Choice of Rigs. U.S. ships normally transferfuel by STREAM rig, by spanwire rig, by the close-inmethod on some non-oiler types, or by the spanline rig.The STREAM rig is preferred because it permits greatership separation. The choice of rig is governed by:3-1 ORIGINAL
