Alongside

Control Ship Approach Ship1stLine

BRAVO closed up iftransferring fuel or ammo

*Displayed where best seen


2/32

Alongside

Control Ship Approach Ship

Bravo at Dip - have temporarily stopped supplying/receiving fuel


3/32

USE OF

FLAG


4/32

Use of the flag PREP

(Receiving Ship only)

PREP is placed at the dip

15 minutes prior to

anticipated breakaway.


5/32

Alongside

Delivery Ship Receiving Ship

15 minutesto breakaway

*Heads up to nextships in line


6/32



PREP is closed up

when disengaging last

station.


7/32

Alongside


Fuel transfer completeand disengaging at

last station


8/32



PREP is hauled down

when the last line is

clear.


9/32

Breakaway


All lines clear,Haul down Prep


10/32

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


12/32

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


14/32

UNREP Communications

Carried out via radio telephone, flashinglight, flaghoist, semaphore, sound-

powered phone, and megaphone


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


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

Connected Replenishment

RiggingCargo

STREAM Method

Highline Method Burton Method

Housefall Method

Fuel

STREAM Method

ConventionalSpanwire

Double hose rig

Close-in method Astern fueling


18/32

Fueling at sea - largest volume of fueltransferred by oilers


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


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


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


22/32

Fuel STREAM, single hose with probe


23/32

STREAM Saddle whips position the hose while

refueling and serve to retrieve the hoseafter fueling is completed

rig brought across by messenger


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


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


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


27/32

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


28/32

Refueling Coupling

Probe - consists of fueling probe onhose

Receiver bell that seats probe


29/32

Single probe and receiver


30/32


31/32

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


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
