VERTICAL REPLENISHMENT CONTROL

..
Cabability of augmenting and enhancing alongside replenishment by transfer of cargo and personnel via helicopter from one ship to another
..
Receiving ship stationed
within reasonable range
..
Simultanious
VERTREP / CONREP
possible
Factors Affecting VERTREP
WIND
..........relative wind  15-30 knots ideal
..........relative wind 330 -030 is optimum
..........helos should take-off and make
..........approaches into relative wind
SHIP STATIONING
..........alongside, lifeguard station,
..........screen stations, or anchor
SHIP PRODUCED INTERFERENCE
..........hot stack gas over pick-up / drop area
TEMPERATURE / ATMOSPHERIC PRESSURE
..........temp increase = lift decrease
..........pressure decrease = lift decrease
PILOT FATIGUE
..........6 - 8 hours pilot endurance during day
..........2 - 3 hours pilot endurance at night
HELICOPTER FUEL LOADING
..........full tank subtracts amount of cargo
..........that can be lifted
Red = FOULED DECK
Landing / Takeoff Prohibited

Amber = Engage /
..............Disengage Rotors

Green = Clear Deck
Landing / Takeoff Permitted
Receiving Ship
flies HOTEL ONE
during
 VERTREP's
PLAYERS
 Heliocopter Control Officer (HCO)
....... White Jersey...... Supervises all flight OPS and safety
Landing Signalman Enlisted (LSE)
....... Yellow Jersey..... Visually signals movements of helo
Chock and Chain
....... Blue Jersey........ Secure / Unsecure helo on deck
Fueling Team
....... Purple Jersey
Firefighting Team
....... Red Jersey
Damage Control Assistant (DCA)
....... Supervises all firefighting efforts
PROCEDURES
 Maximum amount of cargo staged on delivery ship
....... Hook-up man slips eye of pendant over cargo hook
Helo flies cargo as staged to receive ship
....... Once load lowered, pendant slack and helo releases load
....... Load broken down and cleared from flight deck drop zone
Personnel transfer by hoist
SAFETY
 1. All flight deck personnel wear a color-coded cranial, color-coded MK1 inflatable lifevest, long sleeve jersey, safety shoes, and pair og goggles.
2. No loose clothing or hats.
3. Keep visitors away from the pick-up area.
4. NEVER try to steady a swinging load.
5. Keep radio comms to helo at minimum, prevent pilot distraction.
6. DO NOT create foreign object damage (FOD)
7. Do not allow hook-up man to position himself between load and edge of flight deck.
8. NO flash cameras
VERTREP
ADVANTAGES
 1. Reduction in overall time required to replenis a force.
2. Reduction in time screening ships are off station.
3. Capable of replenishing ships in dispersed formation.
4. Capable of replenishing ships in heavy weather when an alongside transfer is difficult.
5. approach, hookup, and disconnect time required to go alongside is eliminated.
VERTREP
DIS-ADVANTAGES
 1. Transfer rate is lower than that of CONREP for large quantities of cargo.
2. Night - lower delivery rate due to reduced visibility, depth perception, and visual references for pilot.
