Objectives• Identify various types of ships that are used to
supply fuel and cargo• Identify various types of equipment used during
UNREP• Describe procedures for conducting a safe UNREP• Name various types of replenishment rigs used
during fueling and cargo transfer• Recognize the different types of standard
tensioned replenishment alongside method (STREAM) rigs used
• Identify procedures for conducting a safe VERTREP
• Describe the type of equipment used in VERTREPFrom NROTC, 12-22-2007
Introduction• The primary aim of an UNREP is the
safe delivery of the maximum amount of cargo and fuel in the minimum amount of time
• The operation must be conducted without interfering with the mission of the force
• Using UNREP procedures, a force can remain at sea and on station indefinitely
Types of Underway Replenishment
• Connected Replenishment (CONREP)a method of transferring fuel, ammunition, and stores from one ship to another through lines and hoses connecting the two ships.
Types of Underway Replenishment
• Vertical Replenishment (VERTREP)a method of transferring ammunition
and stores from one ship to another by helicopter
Replenishment Ships
Single purpose vs. Multi-purpose
Navy vs. Military Sealift Command Replenishment

Replenishment Planning1 week - 4 days prior
submit logistics request (RASREQ)
• requested UNREP date• rendezvous point• fuel requisition• stores requisition
Replenishment Planning1 week - 4 days prior
RASREQ reply
• name of delivery ship• rendezvous location and time
(considerations?)• breakdown of supplies to be transferred• expected replenishment course / speed
Day Prior to Replenishment
• Conduct UNREP brief• ship/station sequence• cargo sequence / flow• masthead height of UNREP ship• replenishment course / speed• factors that could affect UNREP - sea state,
wind direction, operational considerations• emergency procedures• safety briefing
Day of Replenishment
• Rendezvous with UNREP ship• Set UNREP detail• Safety brief onstation• Take station on UNREP ship (as
directed)
Personnel Requirements at UNREP stations
• 1 Safety Officer (white helmet)• 1 Rig Captain (yellow helmet)• 1 Signalman (green helmet)• 2 Phone talkers (green helmets)• 1 Gunners Mate (red helmet and vest)• 15 line handlers (blue helmets)• 4 riggers (blue helmets,goggles, face
shields)• 1 Corpsman (white helmet w/red cross)
Ready, aim, DUCK!
MK87 Mod1 Line Throwing Rifle - propels a buoyant rubber projectile attached to a spool of international orange shotline
Safety Officer• Qualify PQS Safety Officer, Underway
Replenishment• Primary responsibility = prevent
unsafe activities on station• conduct safety brief to all personnel• ensure all personnel are in
Kapoks/MK5s and proper battle dress with all watches and jewelry removed
• Be familiar for procedures with receiving rig
General Safety • Life buoy watches stationed• Chemlights worn by all personnel
at night• line handlers use “hand-over-
hand” method• smoking lamp is OUT throughout
the ship while transferring fuel/ammo
UNREP Principles and Procedures
• Receiving Ship• Normally the approach ship• Maintains station on the delivery ship• receives fuel, ammunition, or stores
from the supply ship

While In Waiting Station
• Examine the wake of UNREP ship• Your wake should be parallel / keep
about 50yd separation between wakes
• Adjust speed to match UNREP ship
• Determine lateral separation using Radian Rule
Lateral Separation Requirements while
Alongside• 100-120 ft (35-40yds) for most
combatants
• 150ft (50yds) for carriers / less maneuverable ships / inclement weather

UNREP Principles and Procedures
Romeo Corpen / Speed:• Naval terminology for replenishment course and speed
*speed normally 13-15 knots-never < 8 knots = reduce rudder effect-never > 15 knots = Venturi effect
• Considerations for selection include sea conditions, wind direction and velocity
Waiting station• 300-500 yards astern• Compare gyros/engine rpm• Use ROMEO flag signals accordingly
ApproachAdjust course and speed to take station 120 feet off to the side of the Control Ship.
120 feet
Alongside•Find a "range" on the other vessel in order to gauge relative position fore/aft.
•Use Distance line to determine range between vessels.
•Order small course and speed changes to maintain relative position.
Breakaway•Increase speed.•Order small course changes away until well clear.•Never cross the bow of the Control Ship.
USE OFFLAG
USE OFFLAG
Approach ship takes station in waiting station 300-500 yards astern of control ship and waits for further instruction from control ship
Use of the flag ROMEO (Control Ship)
ROMEO is placed at the dip on side with the rig.
Meaning: I am steady on ROMEO course & speed and preparing to receive you alongside.
Signals While inWaiting Station

Coming Alongside• Slow to Romeo speed as necessary• Switch to RPM engine orders• Line up the rigs• Line-throwing guns on Delivery ship
send over messengers from each station to opposite stations on receiving ship• Exception = danger of a/c on deck,
receiving ship fires shotlines at delivery ship
Coming Alongside• Word passed over the 1MC:
• Shot-delivering ship = “On the (receiving ship’s name), stand by for shot lines. All hands topside take cover.” • One whistle signal from each station on
delivery ship
• Shot-receiving ship = “On the (ship’s name), stand by for shot lines at (stations concerned). All hands topside take cover.• Two whistle signals from each station on
receiving ship• Three whistle signals - delivery ship firing shot
Use of the flag ROMEO (Control Ship & Approach ship)
ROMEO is hauled down when the first messenger line is across.
While Alongside
• Maintain relative position• 1-2 rpm speed changes• ½° course changes
• Maintain lateral separation using phone-distance line
• Be aware of spanwire tension/detension
