Cargo Drop Reel With Mk 6 Dollyof heavy lifts to a sliding padeye. The CDR is normallynot needed but may be used. For sliding-padeye operatingprocedures, see paragraph 6.14.6.7.2 Fixed-Padeye Receiving Station. Fixedpadeyes are permanently mounted on a bulkhead, kingpost,or outrigger above the landing area. Figure 6-13shows a typical rigging of a fixed-padeye receiving station.Although fixed-padeye mountings vary from shipto ship, all must meet certain requirements for attachmentof the STREAM rig:1. One padeye with a long link — for connectingthe 1-3/8 inch (36.9 mm) pelican hook on thehighline.2. One or two additional padeyes — for attachingthe fairlead block(s) for the rig messenger orouthaul (depending on the STREAM rig used).3. When the receiving station provides a handtendedor winch-tended outhaul, the padeye forthe fairlead block must be 6 inches (152.4 mm)to 18 inches (457.2 mm) below the padeye forthe highline — to give direct pull on the trolley.Since a fixed padeye keeps the highline at a singlepoint above the landing area, a CDR must be attachedto the trolley for lowering the load at the receiving station.Paragraph 6.15 provides procedures for operatingthe CDR. In case there is a casualty to the CDR, the tension/detensionmethod may be used to lower the load(see paragraph 6.16).6.7.3 Pendant Receiving Station. A pendant receivingstation, like the fixed-padeye receiving station,keeps the highline at a fixed height above the deck. Figure6-14 shows a typical rigging of a pendant receivingstation. The pendant is 1-1/8 inch (28.5 mm) wire ropewith an eye and a long link at each end. The pelicanhook on the highline is attached to the outboard longlink (toward the delivery ship), the pendant is hauledinto working position, and the long link on the inboardend is secured to a pelican hook shackled to a deckpadeye. The pendant is used primarily with a kingpost,tripod, or STREAM support leg.Some installations may have rigging platforms thatpermit access to the pelican hook at the kingpost. Useextreme caution when tripping the kingpost pelicanhook and clear the station prior to easing the highlineover the side with the easing-out line.6-16 ORIGINAL
