Retrieve the hose messenger and buoy on thereel or on deck.7. Retrieve the position line and buoy using thegypsy winch.8. See the maintenance manual for emergencyoperation of the hose rig and post-operationalprocedures.5.7.4.11 Communications Required in DeliveryShip1. Between stern and forward winch operator2. Between stern and bridge3. Between stern and pumproom4. Between bridge and pumproom.5.7.5 Delivery Ship System Description —Lay-On-Deck Rig. The delivery ship passes a 6-inch(152.4 mm) hose rig to the receiving ship maintaining position600 feet (184.5 m) astern. See Figure 5-1. Details of thestreaming procedure are provided in the paragraphs below.5.7.5.1 Astern Refueling Hose Assembly. Theastern refueling hose is made up of three flights to permitstowage of the partially assembled rig and to providea greater degree of handling ease. Figure 5-11shows the hose assembly. Total length of all threeflights is 745 feet (227.0 m). Each flight consists ofthe following components:FLIGHT 11. One 15-foot (4.5 m) length of hose with couplingon outboard end2. Five 50-foot (15.2 m) lengths of hose3. One 10-foot (3.0 m) length of hose with securingadapter4. Length of Flight 1 is 275 feet (83.8 m).FLIGHT 21. Five 50-foot (15.2 m) lengths of hose2. One 10-foot (3.0 m) length of hose with securingadapter3. Length of Flight 2 is 260 feet (79.2 m).FLIGHT 31. Four 50-foot (15.2 m) lengths of hose2. One 10-foot (3.0 m) length of hose with securingadapter3. Length of Flight 3 is 210 feet (64.0 m).Flight 3 is intended, when required, to provide an additionalflight of hose for foul-weather operations. Flight 3is not normally streamed during fair-weather operations.The three flights are stowed ready for streaming.Flight 1 is stowed in horizontal rollers along the poopdeck and walkways. Flights 2 and 3 are lashed in stowageracks adjacent to the horizontal rollers.5.7.5.2 Conical Cap, Messenger Bridle, SecuringAdapter, NATO Coupling, and Hose EndAssembly. Refer to Figures 5-5, 5-6, and 5-7. Riggingis the same as described in paragraph 5.7.4.3, exceptthat the modified B-end of the breakable-spool isfitted on the outboard end of Flight 1. Each end of Flights2 and 3 is fitted with protective caps to prevent any contaminationof the hose’s interior from an exterior source.5.7.5.3 Messenger and Position Buoy Assemblies.Refer to Figure 5-8. These assemblies are describedin paragraph 5.7.4.4.5.7.5.4 Delivery Ship Preparations for Streamingthe Hose. A 3/4-inch (19.0 mm) recovery wireis fairled from a block that is in line with the path of thehose. The recovery wire will be shackled to the conicalcap on the inboard end of each flight streamed (Figure5-6). It controls the rate at which the hose is payed outas the hose is streamed and is hauled in to recover thehose at the end of the replenishment operation. Two securingpendants are installed — they are attached to thesecuring adapter clamp to restrain each flight as it isstreamed.The stern of the delivery ship is fitted with a closedstern roller (Figure 5-12). A fairlead block, strapped tothe top of the stern roller and in line with the hose, providesa fairlead for the easing-out messenger. The easing-outline is 2-1/2-inch (63.5 mm) nylon. Variousblocks provide a fairlead for the easing-out messengerto the gypsy head of a stern winch (Figure 5-12).5-15 ORIGINAL
