forward to aft (or vice versa), when filling amidship emergency tanks (on ships so equipped), and when off-loading JP-5. The common suction and discharge headers of the transfer pumps are interconnected with the suction and discharge headers of the service pumps. This arrangement enables the service pumps to be used as transfer pumps (normally for off-loading JP- 5). Be-cause of insufficient (static) head lift and the low pumping capacity of the transfer pumps, they are not normally used for transferring JP-5 off the ship. The cross-connections between the respective suction and discharge headers are fitted with a spectacle flange or a line blind valve (blank side in), and a cutout valve (normally locked closed). Reclamation System The reclamation system provides the capability to reclaim JP-5 received from hose flushings, JP-5 tank stripping operations, and the initial flow during a fueling at sea (FAS). The water and sediment received from these operations are permitted to settle out in the contaminated-JP-5 settling tanks. JP-5 drawn off by the designated JP-5 transfer pump is discharged through the reclamation prefilter and fiber/separator and then into JP-5 storage tanks. STRIPPING SYSTEM There are two independent stripping systems in each JP-5 pump room. One system uses motor-driven pumps and is interconnected with all JP-5 tanks (both storage and service). The other system uses hand-operated pumps and is installed in service tanks only. The systems we will describe here are the typical setup for one pump room. Since they operate independently, we will describe each separately. Motor-Driven Stripping System The motor-driven stripping system (fig. 4-3) con- sists of two low-capacity pumps, manifolds, and Figure 4-3.—Typical motor-driven stripping system. 4-5
