The approach ship when on station and ready to make an approach on the control ship hoists ROMEO at the dip on the rigged side and closes up ROMEO when starting its approach. The control and approach ships will display the dayshape signal for restricted movement (BALL-DIAMOND-BALL) when the approach ship closes up ROMEO. The dayshapes will be hoisted on the unrigged side or centerline and hoisted from 30 minutes prior to sunrise until 30 minutes after sunset. Alongside Procedures ROMEO is hauled down by both ships when the messenger is in hand. BRAVO is closed up by both ships where best seen to indicate the transfer of fuel or explosives. BRAVO may be brought to the dip during the transfer to indicate a temporary interruption. PREP is hoisted to the dip by the receiving ship to indicate that disengagement is expected in 15 minutes. PREP is closed up to indicate completion of replenishment and disengaging at final station. PREP is hauled down when all lines are clear. DAYSHAPES are hauled down when each ship is clear and free to maneuver in an unrestricted manner. Emergency Breakaway Procedures Emergency breakaway can be initiated by either the delivery or the receiving ship. The initiated ship will hoist the emergency breakaway signal (EMERGENCY SIX). This signal is answered by all ships engaged in the emergency breakaway. Along with the flaghoist signal, the initiating ship will sound six short blasts on the ship’s whistle. Emergency signals will be passed to ships in waiting and to screen commanders. NIGHTTIME PROCEDURES Nighttime UNREP procedures require special equipment. The equipment is as follows: Signal lights fitted with screening hoods with a red filter and a 3-inch reducing diaphragm Infrared equipment Flashlights and wands Multipurpose lights Adequate supply of power sources Approach/Alongside Procedures The position of ROMEO is passed between the control and approach units. This is usually done by flashing light or voice radio. PREP is passed to the control vessel, ships in waiting station, and screen commanders. Either visual or voice communication can be used, depending upon the OOD's preference. Make sure when you are using flashing light not to train the light on the conning stations. This could blind the OOD. The use of the yardarm blinkers must be avoided. Restricted Movement The control ship and the approach ship will display the nighttime signal for restricted movement (special-task lights, RED over WHITE over RED) in the same manner as for the dayshapes. TRANSFER-STATION MARKERS Transfer-station markers are displayed to indicate the type of commodity that is being transferred at that station. Commodity being transferred by day (fig. 8-7) is indicated by a 3-foot-square piece of bunting, metal, or painted area. By night a light box (fig. 8-8) that has nine holes, each fitted with a red lens, is used. DISTANCE MARKERS Distance markers on the bridge-to-bridge distance line are arranged as shown in figure 8-9. The distance line markers are used to let appropriate personnel know the distance between the approach ship and receiving ship when alongside. The daytime and nighttime use of distance markers are described in the following paragraphs. Daytime These markers are colored cloth, nylon-coated fabric, or painted-canvas; each is 8 inches by 10 inches; they are spaced at 20-foot intervals, from 0 to 300 feet. The markers are color coded beginning with green, followed by red for 20 feet, yellow for 40 feet, blue for 60 feet, and white for 80 feet. The cycle then repeats itself, green for 100 feet, red for 120 feet, and so forth. Nighttime At nighttime, two blue chemical lights are used, one on each side of the 60-, 100-, 140-, and 180-foot 8-18
