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

pig methods Remating line removed and manual release

lever tripped

FAS scenario using STREAM

w/ probe coupling Delivery ship hauls in hose rig and de-tensions spanwire

Receiving ship trips pelican hook upon wordfrom delivery ship and eases wire clear ofship

All lines returned to delivery ship

REPLENISHMENT AT SEA


11/31

Replenishment at Sea

Mission = safe delivery of maximumcargo 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


12/31

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


13/31

Personnel STREAM

Method of transferring personnelunderway

Rig uses highline winch and ramtensioner to maintain tension onhighline

Suspended transfer chair (bosn chair)on STREAM trolley inhaul/outhaul lines transport chair


14/31

Synthetic Highline

Used to transfer personnel, provisionsand light freight

Highline is 4-inch double braidedpolyester line hand tended by minimum25 personnel

Inhaul/outhaul require minimum of 10personnel each

Transfer chair attached to trolley thatrides on highline Max load capacity 600 lbs


15/31

Safety precautions fortransferring 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/heavyweather

VERTREP


17/31


18/31


19/31

VERTREP Disadvantages

Transfer rate is lower than that ofCONREP for large quantities of cargo

NIGHT - lower delivery rate due toreduced visibility, depth perception, andvisual references for pilot


20/31


21/31

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


22/31

VERTREP

Procedures Receiving ship

stationed within

reasonable range

Simultaneous VERTREP/CONREPpossible

Deck Status Lights

Red light - fouled deck landing/take-off prohibited

Amber light - engage/disengage rotors

Green light - clear deck landing/take-off permitted

26/31

VERTREP Players Firefighting Team

red jerseys

Damage Control Assistant (DCA) supervises all firefighting efforts


27/31

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 cargohook

Helo flies over to receiving deck once load lowered, pendant slack and helo

releases cargo

load broken down and cleared from flight deckdrop zone

Personnel transfer by hoist

29/31

VERTREP Safety

1. All flight deck personnel wear a color-coded cranial, color-coded MK 1 inflatablelifevest, 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.


30/31

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 flightdeck8. NO flash cameras
