Replenishment Terms

• Underway Replenishment (UNREP)
• any method of transferring fuel, ammunition, and
  stores from one ship to another
• Replenishment at Sea (RAS)
• same as above specifically for fuel transfer
• Fueling at Sea (FAS)
• any method of transferring fuel

9
Replenishment Terms

• Connected Replenishment (CONREP)
• a method of transferring fuel, ammunition, and
  stores from one ship to another through lines and
  hoses connecting the two ships.
• Vertical Replenishment (VERTREP)
• a method of transferring ammunition and stores
  from one ship to another by helicopter

10
Connected ReplenishmentMethods

• Cargo
• STREAM Method
• Highline Method
• Burton Method
• Housefall Method

• Fuel
• STREAM Method
• Astern Refueling Method
• Close-In Method

11
STREAM

• Standard Tensioned REplenishment Alongside Method
• uses a tensioned spanwire to support the cargo
  trolley or the fueling hose from the delivery
  ship to the receiving ship

Replenishment Terms

• ROMEO CORPEN / ROMEO SPEED
• Replenishment Course and Speed
• Course and speed used during UNREP

15
Replenishment Terms

• Control Ship
• Guide
• Responsible for staying on R CORPEN and SPEED
• usually the delivery ship except when receiving
  ship is a carrier

16
Replenishment Terms

• Approach Ship
• Responsible for making the approach on the
  control ship

17
Replenishment Terms

• Delivery Ship
• usually the control ship
• supplies fuel, ammunition or stores to the
  receiving ship
• Receiving Ship
• receives fuel, ammunition, or stores from the
  supply ship

18
Replenishment Procedures

• 3-4 days prior
• receiving ship submits a LOGREQ
• LOGREQ (Logistics Request)
• requests stores, fuel, parts
• LOGREQ reply
• name of delivery ship
• rendezvous location and time
• breakdown of supplies to be transferred
• expected R CORPEN/SPEED

19
Replenishment Procedures

• Day of replenishment
• Rendezvous at appointed place and time
• Control ship
• takes tactical control of all ships to be
  replenished
• establishes R CORPEN/SPEED
• assigns stations and order of connected
  replenishment

1. Steady on R Corp/Spd 2. Making preps to
receive on starboard side
In waiting station
23
In Waiting Station

• Examine the wake of control ship
• Your wake should be parallel / keep about 5yd
  separation between wakes
• Match speeds with control ship
• Determine Lateral Separation Using Radian Rule

24
Lateral Separation

• 100-120 ft (30-40yds) for most combatants
• 150ft (50yds) for carriers / less maneuverable
  ships

Coming Alongside

• Two methods
• Coast-in Method
• Slow to R Speed at a predetermined point and
  coast in
• Back Down Method
• All Back 2/3, then before ship slows too fast,
  speed up engines to R Speed

36
Breakaway

• Receiving ship returns all lines and rigging in
  an orderly fashion.
• Delivery ship returns phone and distance line.
• Receiving ship prepares breakaway song.

37
Emergency Breakaway

• Accelerated normal breakaway.
• Either ship can initiate for any reason
• engineering casualty
• steering casualty
• Sound six short blasts on whistle
• Sound Emergency Breakaway over 1MC
