CHAPTER 2 - DESIGN, EQUIPMENT AND SYSTEM DATA
OVERVIEW
Chapter 2 covers the design features and technical data on the equipment and materials used in a typical Tactical
Petroleum Terminal. Section I is an overall description of the terminal and includes reference to a Piping and Instrument
Diagram (P&ID) and typical plot plans. The requirements for the fabric collapsible tank pads and berms (firewalls) are
also covered. Section II defines the equipment used, exclusive of piping, hose, valves, and fittings which are defined in
Section III. Section IV describes the assembled systems of equipment, pipe, hose, valves and fittings. Drawings and
diagrams required for the installation, operation, and maintenance of the TPT are included in this chapter. Section V
covers system hydraulics, i.e., estimated flow rates vs. pressure drop under various conditions. Subsequent chapters on
installation, operation and maintenance will refer back to the information in Chapter 2 as necessary.
SECTION I - GENERAL DESIGN DATA
2-1 General Design Information
The theory of operation and a general functional description of a TPT is covered in Chapter 1 Section II. The following
information and the associated drawings and illustrations further define a TPT.
2-1.1 Piping and Instrument Diagram Fig 2-1
The Piping and Instrument Diagram is a standard industry tool used to control design and construction and define a
system. It is used as an important and primary reference for operations. It should be studied carefully. The P&ID
schematically shows all equipment, instruments, piping, hoselines, and valves. Each operable item has an identification
number. Refer to para. 2-1.2 below for the equipment identification system. The P&ID shows the basic physical
characteristics of size and capacity. On Fig 2-1 the fuel supply to the TPT enters the switching manifold from the
associated pipeline or from tanker-trucks. The fuel is transferred from the switching manifold to any module or tank in
the appropriate fuel unit (diesel, mogas, or jet fuel). The fuel is discharged through the fuel dispensing assembly or can
be returned to the associated pipeline system depending on the needs of the particular operation. Normally, fuel is
received into the secondary module tanks and discharged through the dispensing assembly from the primary module
tanks. The fuel can be transferred to any tank within the fuel unit. Fuel can also be transferred from one fuel unit to
another within the same TPT by removing or bypassing the meter strainer assembly in the receiving line or by field
connecting the line normally discharging to the associated pipeline system to the switching manifold. The details of
operation are covered in Chapter 4.
2-1-2 Equipment. Valve. & Instrument Identification System
a. The equipment, valve and instrument identification system used on the P&ID and throughout this manual
comprises a three-part code. The first part, letter or letters, indicates the type of equipment; the second part is the
identification or series number; and the third part, letter or letters, the service.
