SECTION IV - STORAGE AND TRANSFER SYSTEMS
2-6 General. The equipment described in Section II, paragraphs 2-4.1 through 2-4.8 and the hose, pipe, fitting and
valve assemblies described in Section III are installed in such a way as to make up the storage and transfer systems
described below. Specific drawings are referenced for each section. Reference to the P&ID Fig. 2-1 will clarify the
relationship of the systems. Actual installation of the system elements is described in more detail and in appropriate
sequence in Chapter 3.
2-6.1 Typical Primary Modules (3 Units)
NSN 3835-01-210-5611
a.
The primary tank farm module is the holding area for fuel dispensing activities within the TPT. Fuel is pumped
directly to the fuel dispensing assembly from the storage tanks of the primary module. Should the need arise, it
is possible to pump product from the primary module back to a secondary module, or to the pipeline system.
b.
A primary module consists of three 6-inch aluminum cross assemblies (see Fig.2-38), two 5000 Bbl collapsible
fabric tanks (see Fig. 2-11 and para. 2-4.1), two 600 GPM hoseline pumps (see Fig. 2-13 and para. 2-4.3), and
enough 6-inch hose assemblies, suction and discharge, to connect the components (see Fig. 2-32 and Fig. 2-
33). Range poles (see Fig. 2-23) are provided to assist in determination of the amount of product present in the
fuel tanks.
c.
For typical site layouts and installation plans of a primary module, refer to Fig.'s 2-60A, 2-60B and 2-60C, and
the plot plans for a primary module (see 2-3A, 2-4A. and 2-5A). Note the relative locations of major equipment
components and the maximum and minimum dimensions, particularly the fuel tank spacing. The maximum
distances are dictated by the available hoseline and the minimum distances by safety considerations. The
hoseline arrangements shown are example layouts. Other arrangements may be more suitable for certain
situations.
2-6.2 Typical Secondary Modules (6 Units)
NSN 3835-01-210-5612
a.
The secondary tank farm modules are the main bulk storage facility within the TPT. Product stored in a
secondary module can be pumped to the primary tank farm module or to the pipeline system. The valve
arrangement of the secondary module and the transfer hoseline set make it possible to transfer product from one
tank to another within a secondary module or to transfer product from one secondary module to the other within
the fuel unit.
b.
A secondary module consists of one 6-inch aluminum cross assembly (Fig. 2-38), two 6-inch aluminum wye
assemblies (Fig. 2-39), a double grooved aluminum tee (Fig. 2-55), two 5000 Bbl fabric collapsible tanks (Fig.
2-11 and para. 2-41), one 600 GP;., hoseline pump (Fig. 2-13 and para. 2-4.3) and enough 6-inch hose
assemblies, suction and discharge, to connect the components (Fig.'s 2-32 and 2-33). Range poles (Fig. 2-23)
are provided to assist in the determination of the amount of product present in the fuel tanks.
c.
For a typical site layout and installation plans of a secondary module, refer to Fig.'s 2-61A, 2-61B and 2-61C.
The secondary module plot plans (Fig.'s 2-38, 2-4B and 2-SB) show two secondary modules connected by the
transfer hoseline set. Note the relative locations of major equipment components and maximum and minimum
dimensions, particularly fuel tank spacing and the distance between the two secondary modules. The maximum
distances are dictated by the available hoseline and the minimum distances by safety and space
