forward to aft (or vice versa), when filling amidship
emergency tanks (on ships so equipped), and when
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).
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.
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.
