  1. Identify various types of ships that are used to supply fuel and cargo Identify various types of equipment used during UNREP Describe procedures for conducting a safe UNREP Name various types of replenishment rigs used during fueling and cargo transfer Recognize the different types of standard tensioned replenishment alongside method (STREAM) rigs used Identify procedures for conducting a safe VERTREP Describe the type of equipment used in VERTREP Objectives From NROTC, 12-22-2007

  2. Introduction • The primary aim of an UNREP is the safe delivery of the maximum amount of cargo and fuel in the minimum amount of time • The operation must be conducted without interfering with the mission of the force • Using UNREP procedures, a force can remain at sea and on station indefinitely

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

  4. Types of Underway Replenishment • Vertical Replenishment (VERTREP) a method of transferring ammunition and stores from one ship to another by helicopter

  5. Replenishment Ships Single purpose vs. Multi-purpose

  6. Navy vs. Military Sealift Command Replenishment Ships • MSC Ships • Former naval auxiliaries now manned with civilian or civilian/military crews • Identified with a “T” in front of their type classification and are USNS vice USS

  7. Visually identify by blue and gold stripes painted on their stacks for easy recognition

  8. Oilers (AO) • Cimarron Class (AO-177) • Henry J Kaiser Class (TAO-187) • Services • Complete range of petroleum products • Limited Cargo, Food, Stores • Mail

  9. HENRY J. KAISER Class (T-AO 187) • 13 underway replenishment oilers operated by Military Sealift Command • provide underway replenishment of fuel to U.S. Navy ships at sea and jet fuel for aircraft assigned to ships • UNREP stations on both sides of ship • 2 diesels, 2 shafts, 20 kts • ship’s company = 82 civ/1 O/20 E • Helo platform only

  10. Combat Stores Ships (AFS) • Mars Class (TAFS-1) • Sirius Class (TAFS-8) • Services • Food (Refrigerated and Frozen) • Stores, Cargo • Mail

  12. SACRAMENTO Class (AOE-1) • High-speed oiler, ammunition and supply ship • 4 total (AOE 1-4) • U.S. Navy’s largest combat logistics ship • speed and armament to keep up with CVBG • carries 177,000 barels of oil, 2,150 tons of ammunition, 500 tons of dry stores, and 250 tons of refrigerated stores • reduces vulnerability of serviced ships by reducing alongside time • 4 gas turbines, 2 shafts, 26 kts • ship’s company = 24 O/576 E • 2 CH-46 helicopters • NATO sea sparrow, two CIWS,

  13. SUPPLY Class (AOE-6) • 4 total ships (AOE 6-10) • 4 gas turbines, 2 shafts, 25 kts • ship’s company = 40 O/627 E • 3 CH-46 helicopters • NATO sea sparrow, two CIWS, two 25mm

  14. Ammunition Ships (AE) • Kilauea Class (TAE-26) • Services • Ammunition, bombs, missiles • Limited dry cargo • Helicopters for VERTREP ops

  15. Other UNREP Ships • Aircraft Carriers • top off escort ships • Amphibious Assault Ships • Tarawa Class (LHA-1) • Wasp Class (LHD-1)

  16. Replenishment Planning1 week - 4 days prior submit logistics request (RASREQ) • requested UNREP date • rendezvous point • fuel requisition • stores requisition

  17. Replenishment Planning1 week - 4 days prior RASREQ reply • name of delivery ship • rendezvous location and time (considerations?) • breakdown of supplies to be transferred • expected replenishment course / speed

  18. Day Prior to Replenishment • Conduct UNREP brief • ship/station sequence • cargo sequence / flow • masthead height of UNREP ship • replenishment course / speed • factors that could affect UNREP - sea state, wind direction, operational considerations • emergency procedures • safety briefing

  19. Day of Replenishment • Rendezvous with UNREP ship • Set UNREP detail • Safety brief onstation • Take station on UNREP ship (as directed)

  20. Personnel Requirements at UNREP stations • 1 Safety Officer (white helmet) • 1 Rig Captain (yellow helmet) • 1 Signalman (green helmet) • 2 Phone talkers (green helmets) • 1 Gunners Mate (red helmet and vest) • 15 line handlers (blue helmets) • 4 riggers (blue helmets,goggles, face shields) • 1 Corpsman (white helmet w/red cross)

  21. Ready, aim, DUCK! MK87 Mod1 Line Throwing Rifle - propels a buoyant rubber projectile attached to a spool of international orange shotline

  22. Safety Officer • Qualify PQS Safety Officer, Underway Replenishment • Primary responsibility = prevent unsafe activities on station • conduct safety brief to all personnel • ensure all personnel are in Kapoks/MK5s and proper battle dress with all watches and jewelry removed • Be familiar for procedures with receiving rig

  23. General Safety • Life buoy watches stationed • Chemlights worn by all personnel at night • line handlers use “hand-over-hand” method • smoking lamp is OUT throughout the ship while transferring fuel/ammo

  24. UNREP Principles and Procedures • Receiving Ship • Normally the approach ship • Maintains station on the delivery ship • receives fuel, ammunition, or stores from the supply ship

  25. UNREP Ship Replenishment Station 090° or 270°R alongside UNREP ship Waiting Station 500 yds astern Lifeguard Station 180°R 1,000yds Replenishment Stations

  26. UNREP Ship Waiting Station Waiting Station Starboard 300-500 yds astern

  27. While In Waiting Station • Examine the wake of UNREP ship • Your wake should be parallel / keep about 50yd separation between wakes • Adjust speed to match UNREP ship • Determine lateral separation using Radian Rule

  28. Lateral Separation Requirements while Alongside • 100-120 ft (35-40yds) for most combatants • 150ft (50yds) for carriers / less maneuverable ships / inclement weather

  29. UNREP Ship UNREP Approach for standard 120 lateral separation Waiting Station Starboard 500 yds astern *Bearing offset from base course to tangent of side of replenishment ship at a given distance

  30. 120 Degress Lateral Separation Table Range to UNREP ship (yards)Degrees difference 600 4 500 5 400 6 300 8 200 12 *If you are 600 yards away on unrep course of 150 degrees true, delivery ship bears 146 degrees true from you.

  31. R 60 D =  ( ) 500 60 50 =  ( ) Radian Rule D 50 yds 500 yds R   = 6 degrees to port or 354°R

  32. UNREP Principles and Procedures Romeo Corpen / Speed: • Naval terminology for replenishment • course and speed • *speed normally 13-15 knots • -never < 8 knots = reduce rudder effect • -never > 15 knots = Venturi effect • Considerations for selection include • sea conditions, wind direction and • velocity

  33. Waiting station • 300-500 yards astern • Compare gyros/engine rpm • Use ROMEO flag signals accordingly

  34. Approach Adjust course and speed to take station 120 feet off to the side of the Control Ship. 120 feet

  35. Alongside • Find a "range" on the other vessel in order to gauge relative position fore/aft. • Use Distance line to determine range between vessels. • Order small course and speed changes to maintain relative position.

  36. Breakaway • Increase speed. • Order small course changes away until well clear. • Never cross the bow of the Control Ship.

  37. USE OF FLAG

  38. Approach ship takes station in waiting station 300-500 yards astern of control ship and waits for further instruction from control ship USE OF FLAG

  39. Use of the flag ROMEO (Control Ship) ROMEO is placed at the dip on side with the rig. Meaning: I am steady on ROMEO course & speed and preparing to receive you alongside.

  40. Signals While inWaiting Station Control Ship Approach Ship 1. Steady on R Corp/Speed 2. Making preps to receive on starboard side In waiting station

  41. Use of the flag ROMEO (Approach Ship) ROMEO is placed at the dip on side where rig is expected. Meaning: I am ready to come alongside.

  42. Signals While inWaiting Station Control Ship Approach Ship Ready to come alongside as indicated by side of Romeo Flag

  43. Use of the flag ROMEO (Control Ship) ROMEO is closed up. Meaning: I am ready to receive you alongside.

  44. In Waiting Station Control Ship Approach Ship Ready for your approach In waiting station

  45. Use of the flag ROMEO (Approach Ship) ROMEO is closed up. Meaning: I am commencing my approach.

  46. Commencing Approach Control Ship Approach Ship Ready for your approach Commencing my approach *Increase speed by 3-10 knots over signaled UNREP speed

  47. Coming Alongside • Slow to Romeo speed as necessary • Switch to RPM engine orders • Line up the rigs • Line-throwing guns on Delivery ship send over messengers from each station to opposite stations on receiving ship • Exception = danger of a/c on deck, receiving ship fires shotlines at delivery ship

  48. Coming Alongside • Word passed over the 1MC: • Shot-delivering ship = “On the (receiving ship’s name), stand by for shot lines. All hands topside take cover.” • One whistle signal from each station on delivery ship • Shot-receiving ship = “On the (ship’s name), stand by for shot lines at (stations concerned). All hands topside take cover. • Two whistle signals from each station on receiving ship • Three whistle signals - delivery ship firing shot

  49. Use of the flag ROMEO (Control Ship & Approach ship) ROMEO is hauled down when the first messenger line is across.
