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









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


17 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) white jersey 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 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

31 Homework Friday – U/W Watchstanding Monday – Inport Watchstanding Wed – Exam Review Friday - Exam #3 (05 April) Read Seamanship Chapter 2 Watch Officers Guide Chapters 1-3, 5, 11, 17, Appendix A
