meter strainer assemblies and floodlight sets. The use and operation of the meter strainer assemblies along with the
range poles are already covered in para. 4-3. The other major equipment noted above all have specific technical
manuals published by the manufacturer or the U.S. Army and it is most important that the reader refer to these technical
manuals for detailed operating instructions. This section will primarily reference these technical manuals with special
comment when considered appropriate. All of the major equipment with the exception of the floodlight sets function in
and for the system's operations covered in Section III.
4-9 5,000 Bbl Fabric Collapsible Tank Operation
4-9.1 Information on the 5,000 bbl fabric collapsible tanks is found in para. 2-4.1 and Fig. 2-11. Detailed instructions are
in the ILC Dover technical manual supplied with the tanks.
These instructions must be studied in detail before operating the tanks.
4-9.2 The tanks are filled by opening the appropriate valves at the cross assemblies. For example, note valve V21J on
the cross assembly (assuming cross assembly is under pressure, that is, V20J or V31J open to a hoseline under
pressure) is opened to fill tank T3J as shown on the flow diagram, Fig. 4-1.
4-9.3 The tanks are drawn down by suction from the hoseline pumps after opening the appropriate valves. For example,
valves V22J, V23J and V27J, along with valving on the discharge and downstream of P2J, must be open to draw down
tank T3J with the pump P2J on Fig. 4-1.
4-9.4 The tanks can be drained through the drain connection D supplied with the tank.
4-9.5 It is important to note the following warnings and cautions in operating the 5,000 bbl fabric collapsible tanks.
WARNING
OVERFILL OF FABRIC COLLAPSIBLE TANKS
The fabric collapsible tanks are designed primarily for static liquid head pressure only. The
tank vents are set at 0.10 psig and are incapable of passing large volumes of liquid.
Overfilling will result in a spill through the vent and can, if filling under pressure, result in
overpressure and a tank rupture, causing a major and dangerous spill.
WARNING
CLEAR TANK VENTS
Prior to filling tank, inspect and make sure tank vents are always clear and clean. A plugged
tank vent can cause damage to the fabric tank or cause a loss of pump suction. Make sure
pressure relief feature is operating.
