1. FAS scenario using STREAM w/ probe coupling
Remating line attached to probe and messenger to hold rig in place in case of slipping
Receiving ship requests delivery ship to commence pumping
Upon completion, usually 450 gal in hose
fuel removed by blowdown, back suction, or pig methods
Remating line removed and manual release lever tripped
From NROTC,

2. FAS scenario using STREAM w/ probe coupling
Delivery ship hauls in hose rig and de-tensions spanwire
Receiving ship trips pelican hook upon word from delivery ship and eases wire clear of ship
All lines returned to delivery ship

10. REPLENISHMENT AT SEA

11. Replenishment at Sea
Mission = safe delivery of maximum cargo in minimum time
Type of transfer rig used depends on
type and quantity of cargo
capacity of rig
weight and size of heaviest load
weather/sea conditions

12. Missile/Cargo STREAM Most common and preferred rig
Uses ram tensioner on delivery ship to maintain standard tension on highline
Tensioned highline supports trolley which carries load
inhaul line - tends from trolley to delivery ship
outhaul line - tends from trolley to receiving ship

13. Personnel STREAM Method of transferring personnel underway
Rig uses highline winch and ram tensioner to maintain tension on highline
Suspended transfer chair (bosn’ chair) on STREAM trolley
inhaul/outhaul lines transport chair

14. Synthetic Highline
Used to transfer personnel, provisions and light freight
Highline is 4-inch double braided polyester line hand tended by minimum 25 personnel
Inhaul/outhaul require minimum of 10 personnel each
Transfer chair attached to trolley that rides on highline
Max load capacity 600 lbs

15. Safety precautions for transferring personnel
Dummy load used as test load
Transfer chair designed with flotation device
If chair falls into water, let all lines go and allow it to run free
Not recommended for night/heavy weather

16. VERTREP

17. VERTREP
Capability of augmenting and enhancing alongside replenishment by transfer of cargo and personnel via helicopter from one ship to other
utilizes CH-46 helicopters

18. VERTREP Advantages
Reduction in overall time required to replenish a force
Reduction in time screening ships are off station
Capable of replenishing ships in dispersed formation
Capable of replenishing ships in heavy weather when alongside transfer difficult
Approach, hook-up, and disconnect time required to go alongside eliminated

19. VERTREP Disadvantages
Transfer rate is lower than that of CONREP for large quantities of cargo
NIGHT - lower delivery rate due to reduced visibility, depth perception, and visual references for pilot

20. Factors affecting VERTREP
Wind
relative wind knots ideal
true winds from is optimum
helos should take-off and make approaches into wind
Ship stationing
alongside, lifeguard station, screen stations, or anchor
night - receiving ship abeam
Ship-produced interference
hot stack gas over pick-up/drop area

21. Factors affecting VERTREP
Temperature/Atmospheric Pressure
temp increase = lift decrease
pressure decrease = lift decreases
Helicopter 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

22. VERTREP Procedures Receiving ship stationed within reasonable range
Simultaneous VERTREP/CONREP possible

23. VERTREP
Receiving Ship
flies HOTEL ONE
during VERTREPs

24. Deck Status Lights Red light - fouled deck
landing/take-off prohibited
Amber light - engage/disengage rotors
Green light - clear deck
landing/take-off permitted

25. VERTREP Players Helicopter Control Officer (HCO)
white jersey
supervises all flight ops and safety
Landing Signals Officer (LSO)
Pilot on deck assisting helo with landing
Landing Signalman Enlisted (LSE)
yellow jersey
visually signals movements of helo
Chock and chain
blue jerseys
secure/unsecure helo on deck
Fueling team
purple jerseys

26. VERTREP Players Firefighting Team Damage Control Assistant (DCA)
red jerseys
Damage Control Assistant (DCA)
supervises all firefighting efforts

27. VERTREP Procedures Maximum amount of cargo staged on delivery ship
Helo flies over load on delivery deck
Hook-up man slips eye of pendant over cargo hook
Helo flies over to receiving deck
once load lowered, pendant slack and helo releases cargo
load broken down and cleared from flight deck drop zone
Personnel transfer by hoist

29. VERTREP Safety
1. All flight deck personnel wear a color-coded cranial, color-coded MK 1 inflatable lifevest, long sleeve jersey, safety shoes, and pair of 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 the helo at a
minimum to prevent pilot distraction.

30. VERTREP Safety 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
