CHAPTER 4
JP-5 AFLOAT BELOW DECKS
SYSTEMS AND OPERATIONS
The first time you see the pump room of a
CV/CVN, it is easy to be intimidated. With its com-
plex array of piping, pumps, valves, gages, and mo-
tors, you may feel there is just too much to learn. But
the qualified pump-room operators make it look easy.
In this chapter, we will try to ease you through
this complex system by breaking it down. First we
will discuss the subsystems; then we will cover the
many components that make up these systems; and
finally we will explain operational procedures.
To operate any JP-5 fueling system safely and
efficiently, the ABF must have a thorough knowledge
of the arrangement and limitations of the piping sys-
tems. Although the piping arrangements are similar
for all CV/CVNs, no two ships (not even sister ships)
are exactly alike. Therefore, you should consult your
ship’s blueprints and Ships Information Book (SIB)
for details on its particular system. The information
and diagrams in this chapter are based on the typical
arrangements of various class carriers, small or large,
and old or new.
JP-5 FUELING SYSTEM
LEARNING OBJECTIVE: Identify the subsys-
tems that make up a JP-5 fueling system.
A JP-5 fueling system consists primarily of a
storage system and three separate and independent
pumping systems. The pumping systems are Filling
and Transfer, Stripping, and Service. The tanks in a
JP-5 system are designated under two major catego-
ries: storage and service. Storage tanks are used for
bulk storage of JP-5. Service tanks are used for serv-
icing aircraft. The storage capacity of different classes
of ships depends on the number and size of the ship’s
tanks. Approximate storage capacities for some of the
different classes of ships are listed in table 4-1.
