process. Should this occur, the transfer operation must
be secured until storage tanks concerned have been
restripped; a clean, bright, water-free sample is re-
ceived on the discharge side of the stripping pump;
and the centrifugal purifier is inspected and discrep-
ancies are corrected.
Transferring From Storage to Storage
This operation should rarely be necessary if an
emptying sequence was properly established and fol-
lowed (except when consolidating the fuel load before
receiving). If and when this operation is called for, it
will, in most instances, require transferring JP-5 from
port to starboard, or vise versa, to correct the list on
the ship; or transferring JP-S from forward to aft, or
vice versa, to correct the trim on the ship.
The operating procedure for this operation is the
same as transferring from storage to service with the
1. Purification and sampling procedures are not
2. The transfer piping from the discharge header
of the transfer pumps is aligned to discharge into the
opposite transfer main branch header, from which suc-
tion is being taken (when transferring from port to
starboard, or vice versa), or to the transfer main (when
transferring from forward to aft, or vice versa).
The overflow tank for any nest of tanks
scheduled to receive fuel must be empty before
JP-5 can be transferred into any tank in that
When any transfer operation has been completed,
consolidate to the greatest extent possible the last 24
inches of JP-5 remaining in the storage tanks. (As
much as 5,000 gallons remain in some of the larger
tanks after the transfer pumps lose suction.) This
consolidation must be accomplished by the motor-
driven stripping pump.
The procedure for consolidating the last 24-
inches of JP-5 is the same as that outlined for strip-
ping, except that the stripping pump discharge header
is aligned to direct the discharged fuel into the transfer
main instead of the contaminated-JP-5 settling tank.
From the transfer main, the JP-5 is directed into
preselected storage tanks. Consolidated fuel should
be allowed maximum settling time before it is
stripped before use.
The empty ballast storage tanks are ballasted
(filled with sea water) to preserve the underwater
protection system of the ship. Ballasting must be ac-
complished in accordance with current ships ballast-
ing instruction for each ship.
Tanks on CV/CVNs are ballasted by gravity
through the sea chest valve on the flood and drain
manifold and the single-valved stripping manifold.
On LPHs and LPDs this water is supplied from the
ship's fire main system.
Ballasting procedure is as follows:
1. Follow the tank falling sequence as scheduled
by damage control central to maintain the proper list and
trim of the ship.
2. Open the valves on the single-valved stripping
manifold to the tanks to be filled.
Open an equal number of tanks on the
opposite side of the ship.
ALL tanks that are served by one flood and
drain manifold can be filled simultaneously.
3. Align the valves on the flood and drain mani-
fold for ballasting.
a. Unlock the sliding lock bar by loosening the
two bolts over the oblong slots.
b. Position the lock bar so the circular hole in
the keyhole slot is directly above the raised collar on the
sea chest valve stem.
c. Rebolt the lock bar in position.
Open the sea chest valve.
Sound the tanks to determine the instant they
