Disconnecting Procedures
Delivery ship stop pumping
Delivery ship will retrieve probe after
receiving ship trips manual release lever Delivery ship will detension spanwire
Receiving ship will trip pelican hook
upon signal of delivery ship ease spanwire over deck edge

11/32
Breakaway
Delivery ship returns phone anddistance line.
Receiving ship prepares breakawaysong.
Once all lines clear, receiving shipincreases speed by 5-10 knots when
clear and gradually changes course in1-2 degree increments outboard whenstern clear of delivery ship

Emergency Breakaway!!!

13/32
Emergency Breakaway
Accelerated normal breakaway
Either ship can initiate for any reason
engineering / steering casualty
imminent danger from hostile forces
aircraft emergency
ship separates by more than 240 feet when
using single rig
man overboard with no lifeguard boat
rig parts/major fuel leak
Sound six short blasts on whistle

UNREP Communications
Carried out via radio telephone, flashinglight, flaghoist, semaphore, sound-
powered phone, and megaphone
8/12/2019 19-Underway Replenishment 3
15/32
UNREP at night Darkened ship transfer stations are lit in
red/orange low-density lights. Contour lightsassist the receiving ship in coming alongsideand maintaining station
Romeo signals passed by flashing light or
semaphore
station-marker light box indicates what isbeing transferred
8/12/2019 19-Underway Replenishment 3
16/32
UNREP at night Phone/distance line uses chem lights
4 blue (one on each side) at 60, 100, 140, and180 foot markers
1 red at all markers
Linehandlers life vests are rigged with green
chem light

Fueling at sea - largest volume of fueltransferred by oilers
8/12/2019 19-Underway Replenishment 3
19/32
Factors that affect fueling rig
selection Type of delivery ship (rig availability)
Conditions under which transfer is
conducted Weather/Sea Conditions
Size/draft of receiving ship
shallow draft ships cannot use ramtensioned spanwire
8/12/2019 19-Underway Replenishment 3
20/32
Fuel STREAM
Standard Tensioned REplenishmentAlongside Method
uses a tensioned spanwire to support thecargo trolley or the fueling hose from thedelivery ship to the receiving ship
STREAM rig permits ships to open outbetween 80-200 feet
High suspension of hose keeps it out ofwater during high seas
8/12/2019 19-Underway Replenishment 3
21/32
STREAM Most preferred method
Requires most elaborate rig Hose is carried between two ships on a ram-
tensioned spanwire
Ram tensioner adjusts for minor changes in
hull separation maintains constant tension on the highline
by paying out/taking in wire highline - wire rope, mechanism carrying
load will ride on line
Hose supported by flow through saddleswhich hang from trolley blocks that ride alongspanwire
8/12/2019 19-Underway Replenishment 3
22/32
Fuel STREAM, single hose with probe
8/12/2019 19-Underway Replenishment 3
23/32
STREAM Saddle whips position the hose while
refueling and serve to retrieve the hoseafter fueling is completed
rig brought across by messenger
8/12/2019 19-Underway Replenishment 3
24/32
Conventional Spanwire
Identical to fuel STREAM rig exceptspanwire not tensioned
manually operated to adjust for minor andmajor changes in distances btwn ships
Most preferred rig if STREAM
unavailable Distance between ships 80-200 ft
8/12/2019 19-Underway Replenishment 3
25/32
Double Hose Rig
Variation to both the conventionalspanwire and fuel STREAM where two
hoses are suspended from samespanwire
Two types of liquid may be transferred
at same time
8/12/2019 19-Underway Replenishment 3
26/32
Close-In Method
Used when delivery ship not equippedwith spanwire rig or receiving ship
cannot support spanwire Hose supported by whips leading from
hose saddles to high projections on
delivery ships Distance between ships 60-100 ft

Astern Fueling
Normally not employed by larger shipsin U.S. Navy
NATO agreements require that allescort type vessels be capable ofreceiving fuel from designated
merchant tankers by alongside andastern methods

Refueling Coupling
Probe - consists of fueling probe onhose
Receiver bell that seats probe
8/12/2019 19-Underway Replenishment 3

FAS scenario using STREAM
w/ probe coupling Shotline passed - messenger attached to
shotline received on receiving ship andhauled in
Spanwire attached to messenger comesaboard, end fitting attached to pelican hook
Delivery ship tensions spanwire
MINIMUM SEPARATION OF 140 FT REQ Rig hauled over by receiving ship by heaving
around on messenger delivery ship pays out rig until probe seated
8/12/2019 19-Underway Replenishment 3
32/32
FAS scenario using STREAM
w/ probe coupling Remating line attached to probe andmessenger to hold rig in place in case ofslipping
Receiving ship requests delivery ship tocommence pumping
Upon completion, usually 450 gal in hose fuel removed by blowdown, back suction, or
pigmethods Remating line removed and manual release
lever tripped
