The assault hoseline system is intended to be used as a temporary pipeline and can transport fuel at a
maximum rate of 500 to 550 barrels per hour across 10 miles of flat terrain. The use of the assault hoseline
for transportation of bulk petroleum has become increasingly important as an expedient means of providing
adequate quantities of bulk petroleum in the shortest time possible.
PART A - THE ASSAULT HOSELINE SYSTEM
Refer to FM 10-67-1 (Concepts and Equipment of Petroleum Operations), Chapter 27, for illustrations and a
more detailed description of the assault hoseline equipment. Six soldiers and the following equipment are
needed to lay out and assemble the hoseline:
Thirteen flaking boxes The 4-inch, lightweight, collapsible rubber hose is packed into the flaking boxes
with 1,000 feet to a box.
One 350-gallon-per-minute (GPM) pumping assembly The 350-GPM pump is equipped with a pressure
regulator that controls the idle of the pump and adjusts the pressure if there is a significant decrease in
pressure in the hoseline.
A flow control kit The flow control kit consists of two 4-inch gate valves; one 4-inch T; two check
valves; two 4-inch hose assemblies; one strainer assembly; one roll of electrician's tape; and couplings,
nipples, adapters, and coupling halves.
Ten steel roadway crossing guards The roadway crossing guard must be installed to protect the
hoseline when it crosses a roadway.
A hose suspension kit The hoseline suspension kit consists of 350 feet of wire rope, 350 feet of manila
rope, 25 wire-rope clips, 60 shackles, 60 hose saddles, 14 steel pickets, 4 steel blocks, 4 turnbuckles,
and 4 wire-rope thimbles.
A hoseline displacement and evacuation kit The hoseline displacement and evacuation kit consists of
a ball injector, a ball receiver, a displacement ball, an air eductor, 8 grooved couplings, and 16 pipe
A hoseline packing kit The hoseline packing kit consists of a chain hoist, a hose puller, two hose
clamps, and a metal storage chest.
A hose repair kit The repair kit contains tools and materials needed to repair the hoseline system.
PART B - SAFETY AND ENVIRONMENTAL CONSIDERATIONS
Prior to the start of the mission, the troops must be briefed on any safety or environmental hazards they may
encounter. The briefing should include the proper response to such hazards and other information which will
enable them to correctly address less serious infractions independently. Each mission encompasses
different situations and unit interactions so you need to develop a mission-specific briefing for each; therefore
no one solution can or will be presented in this lesson. If your experience does not afford you a basis for
preparing a briefing, a supervisor should be contacted for additional information.
PART C - SUPERVISING THE LAYOUT, ASSEMBLY, AND TESTING OF
THE ASSAULT HOSELINE
Choosing a Route. Select a direct route which is free of obstacles. If possible, try to parallel an existing
road to aid construction, operation, and security. A route parallel to a secondary all-weather road is better
than a heavily traveled main supply route. Take advantage of natural cover such as fencelines, woods, and
hedgerows. However, do not disturb the natural cover by grading or leveling. Try to avoid rocky areas which
might damage the hose.
It is possible to distribute the hose at speeds up to 35 MPH. However, the recommended maximum
speed is 20 MPH. As the hose is distributed, men spread out along the route (at least two each 1/4 mile),
walk the line to straighten out undesirable kinks or bends, and remove small obstructions which might cause
damage when the hose is pressurized. When distributed on a road, the hose must be picked up from the
roadway itself and moved to a position in the road ditch (Figure 4-1).
