Overview
Section 3: Tank Description
Section 3: Tank Description
Overview
SEI Industries Ltd.’s HIPPO Frac Tank is a collapsible pillow-style water tank designed specifically for oil
and gas exploration and development. The HIPPO tank is easy to set-up and can be used immediately with
almost no site preparation required. The frac tanks are lightweight, fully collapsible, environmentallyfriendly and don't damage the ground beneath them.
One semi-truck can transport 24 tanks with a combined storage capacity of an astounding 1,200,000 USG
(28,800 BBLs (US) or 4560 m3). It would take 57 trucks to transport the same storage capacity in 500 BBL
steel tanks or 228 trips on and off site. Using our optional 2-person Frac Tank Deployment System (FTDS),
one tank can be unrolled and deployed in 10-15 minutes or mop-up in 15-20 minutes.
One individual HIPPO Frac Tank can store 50,000 USG (1200 BBLs (US) or 190 m3). In a day, using a
manifold system, multiple tanks can be set-up to provide whatever volume of storage is required.
Features
•
Convenient: collapsible, lightweight, easy to relocate.
•
Rapidly deployable: SEI's Frac Tank Deployment System (FTDS) can be used to unroll
tanks quickly.
•
Use immediately: almost no site preparation required.
•
Lower transportation costs: one semi-truck can transport 24 tanks at a time reducing costs
dramatically.
•
Quick set-up: one HIPPO Frac Tank can store 50,000 USG (1200 BBLs (US) or 190m3).
In a day, using a manifold system, multiple tanks can be set-up to provide whatever volume of storage is required.
•
Durable: more abrasion and chemically-resistant than other materials, cold-resistant to 50 °C.
•
Less risk of freeze-up: due to its lower profile, only 5’ (1.5 m) high when fully filled, the
HIPPO Frac Tank offers good heat retention and low wind resistance.
•
Customizable: available in standard capacities of 50,000 USG (190 m) or custom capacities, as per customer specifications.
•
Better for the environment: collapsible tank bladders ensure complete isolation from surface soil and water, significantly reduce truck traffic to and from the site and increase site
safety.

Section 3: Tank Description
Tank Construction
Tank Construction
Constructed to endure, HIPPO Frac Tanks are made from a specially developed heavy-duty industrial fabric
that features a thicker and denser coating to ensure a level of durability that will stand up to frequent relocations and punishing outdoor conditions. In addition, all seams are radio-frequency welded (no hot air,
wedge welding or glue).
A removable groundsheet – which can be attached to the HIPPO Frac Tank – is supplied to prevent it from
freezing to the ground during winter operations. SEI’s HIPPO Frac Tank can be shipped via all methods –
by land, sea or air.
Multiple fill/drain ports are provided on the side of every tank for convenient connection to your HIPPO
Frac water system. For additional durability, heavy-duty abrasion patches protect the tank around these fill/
drain ports. Fill/drain piping and bottom drains are optional.
Repair kits, which include up to three different sizes of sealing clamps are included for the purpose of temporarily repairing minor holes, cuts and tears that may occur in the tank wall. It is recommended that all
holes, cuts or tears be permanently repaired as soon as possible. Please contact an SEI representative for
materials and instructions on how to make permanent repairs.
Fabric Description
SEI’s HIPPO Frac Tank industrial fabric is a proprietary high strength, high abrasion-resistant material that
is also chemically-resistant and coloured in high visibility safety orange. It's ideal for use in winter temperatures as low as -50 C (ASTM #D2136) where it can be folded and unfolded in extreme cold. The HIPPO
Frac Tank can also be used constantly with heated fluids up to +71 C (with limited exposure to +82 C). In
addition, the tank's low profile design helps to maintain its fluid temperatures better compared to vertical
steel tanks.
Another feature of this unique fabric is its high resistance to abrasion — an important aspect when tanks are
continually moved from site to site. Typical mil spec fabrics have abrasion resistance of 6,000-13,000 cycles
(ASTM #D3884) while the HIPPO Frac tank fabric has a 73,000 cycle abrasion resistance to handle the wear
and tear of continual movements.
Standard Equipment
Each HIPPO Frac Tank comes complete with a single 2" female NPT fitting at the center of the tank for vent/
overfill protection. Tanks may also come with one or more 2", 3", 4" or 6" fill/drain ports on the side of the
tank. Each port includes both internal and external abrasion resistance reinforcement.
All HIPPO Frac Tanks come with multiple handles to assist with deployment and folding of the tank. A
groundsheet is also secured to the tank handles to prevent the tank from being frozen to the ground during
winter operations.

Ground Preparation and Berm Construction
Section 4: Site Preparation
Ground Preparation and Berm Construction
Selecting the Site
Select a site approximately six feet (1.8 m) larger in each direction than the empty tank size. For best operating conditions, the slope of the site selected should not exceed three degrees in any direction.
Preparing the Site
Clear the selected site of all sticks, stones or other sharp objects that may damage the tank. A ground sheet
is recommended to protect the bottom surface of the tank (optional). Berms may be constructed around
tanks if hazardous chemicals are being used or if required by local regulations. A berm is a low dam or wall
that provides secondary containment in case of a spill. These berms should be at least as large as the dimensions in Section 5. To prevent any liquid spilled from the tank seeping into the soil, SEI can supply a complete environmental secondary protection barrier known as a berm liner.
Berm Precautions
If hazardous chemicals are used in fracking, melted water and/or rain water collected in the secondary containment berm must be contained, treated and disposed of per applicable provincial or territorial regulations
(reference: CCME Environmental Code of Practice for Above Ground Storage Tank Systems, Section 3.7).
Caution
SEI will not be liable for any loss of liquid or related damage. It may become necessary to periodically remove rain water from inside the berm area. Frequent inspections are advisable. An optional RainDrain will facilitate easy drainage of the berm.

Ground Preparation and Berm Construction
Section 4: Site Preparation
Berm Construction
Important Note
The following information on berm construction is intended as a guide only. Berms must be solidly constructed so as to withstand the full force of the fluid, in the event of a spill. A professional
engineer should be engaged to design the berm for your specific application.
The floor of the berm should slope slightly towards one edge to direct rain water away from the tank. Three
types of berm are illustrated below. Most berms can be classified as one of the following:
Combination Cut and Fill
This berm is constructed by excavating material, from below the grade, then placing it on
top of the grade to build the embankment.
100% Fill
The floor of this berm is at the same elevation
as the grade, with the embankments being
built using material brought in from another
location. This method of construction is generally suited to locations at which the following conditions are present:
•
•
•
High ground water
Materials for embankment are not
locally available
Ground at site is difficult to
excavate
Three main types of berms.
100% Cut
This berm is constructed by excavating material, from below the grade, then removing it from the site.
HIPPO Frac Tank Operations Manual (Version B)

Section 4: Site Preparation
Ground Preparation and Berm Construction
Ground Surface Preparation
The ground supporting the HIPPO Frac Tank must be firm enough to prevent the tank from settling after
filling, otherwise the berm liner may stretch and rupture (a soils engineer should be consulted). The grade
and floor of the berm should be sloped to ensure that the tank does not sit in water.
Surface Finish
The interior surface of the berm should be smooth, firm and free of any sharp objects which could puncture
the berm liner. Often the interior of the berm must be prepared by providing several inches of pea gravel
covered with several more inches of soil or sand. This also provides some drainage and helps keep water
away from the liner.
Sump Pump
Every berm should be equipped with a manually-operated pump or drain fitting, which should be located at
the lowest point in the berm, allowing water to be pumped out of the berm.
Installing the Bottom Drain
If your tank bottom is fitted with the optional bottom drain fitting, the pad for the tank
must be graded so the drain fitting is at the
lowest point. The pad must have a smoothly rounded sump or depression to accommodate the drain fitting.
This allows the fitting to sit level with the
bottom of the tank and ensures that the bottom of the tank sits flat on the ground,
avoiding excess strain on the tank fabric.
Installation of tank bottom drain.
HIPPO Frac Tank Operations Manual (Version B)
10
Ground Preparation and Berm Construction
Section 4: Site Preparation
If a drain hose is used, it should be placed in a shallow trench and backfilled with sand level with the surface
of the pad. Provision should be made for drainage so the tank will not be standing in water.
Typical berm liner design. Slope berm away from the tank towards one corner to facilitate pumping out
rain water.

Important Note
If you have the optional Frac Tank Deployment System (FTDS), please see Section 9 for
additional deployment instructions.
Carefully remove the tank from the shipping container (tip crate and roll tank out or remove with lifting harness), unfold and center on the prepared site. Pull the tank flat, ensuring that there are no wrinkles in the
bottom.
The shipping container should be retained for
storage or shipping of the tank. Make note of how
the tank is folded so it can be refolded and returned to the container in the same manner. Remove all tape from the flange cover at the fitting
areas. Visually inspect all fittings to ensure all
sealing surfaces are free of contamination.
Use caution to prevent foreign materials from entering the fitting openings. Visually inspect vent
and filler covers for cleanliness to ensure proper
sealing of gaskets. To ensure leak proof connections, it is recommended that teflon pipe tape or
sealer be used on all threaded fittings. Couple the
vent stack to the center flange of tank. Couple the
fill/drain kit to the corner flange of the tank.

Operational Procedures
Inspecting the Tanks
Prior to filling, check that all connections are tight and that the proper attachments for all auxiliary equipment have been made. Inspect the vent fitting installation to be sure the cap is not plugged.
Filling the Tank
Proceed to fill the tank. Observe tank body, fittings and vent during the filling operation. If any leakage is
detected, the filling should be stopped and the cause of the leak determined and corrected.
1.
Install hose.
2.
Connect grounding cable to pump.
3.
Connect pump unit to the tanker truck.
4.
Open and close valves as required to fill the tank.
5.
Monitor the volume being pumped into the tank; however, also use the height measuring device to
ensure the tank is not overfilled.
6.
Record filling logs.
Caution
Do not exceed the rated capacity of the tank when filling. Overfilling can damage the tank and
will void the warranty.
If a metering gauge is not available at the time of filling, see the recommended maximum filled
heights in Section 10 and use the recommended fill height determination procedure pictured on

Tank Operation
•
Monitor the fill height of the tank.
•
Keep logs when metering.
•
Keep the berm drained of collected water and monitor the drawn water for liquidpresence.
•
Keep the surface of the tank clean, removing any sand or dirt that has fallen on it.
•
Check the vent occasionally for dirt or sand and clean out, if needed.
Purging the Tank
The tank can be purged via the bottom drain, through the vent cap, or through the fill/drain as detailed below:
•
If tank is fitted with the optional bottom drain fitting, it can be used for purging contamination.
•
If the center of the tank is the low spot, contaminants can be purged through the vent cap.
Remove this vent cap and insert a small pipe to the bottom of the tank to pump out contamination.
•
If the fill/drain fitting is at the low spot, it can be used for purging with the addition of
extra fittings. Fit a tee above the flange. Fit the valve or hose to the horizontal outlet of
the tee. Fit the vertical outlet from the tee with a long nipple to get above the liquid level.
Fit a cap to the top of the nipple. Remove the top cap and insert a small pipe to the bottom of the tank to pump out any contamination. This assembly should be supported to
avoid strain on the tank fabric.

Operational Procedures
Section 6: Tank Operation
Emptying the Tank
Reverse the sequence of operations for filling as outlined previously. As the tank is drained, it will begin to
deflate until it assumes a flat position.
Caution
Do not attempt to lift a full tank by the handles as this may damage the tank. The handles are designed
for moving empty tanks and for lifting one end of nearly empty tanks to remove the remaining liquid.
If the tank is to be completely drained, lift the end of the tank opposite the drain fitting when the tank is
nearly empty. This will aid in forcing any remaining liquid toward the fitting for removal. Small amounts
of remaining liquid may be removed through the drain fitting, if the tank is so equipped.
Extending the Service Life of the Tank
As with any equipment, the service life of flexible tanks can be extended with proper care. The main factors
that affect flexible tanks are ultra violet radiation, folding and abrasion, moisture, temperature and the type
of liquid stored.
A flexible tank used in shady, dry, cool conditions and not moved frequently will last longer than one moved
frequently and used in sunny, hot, wet or humid conditions.
The following practices will help extend tank life:
•
When moving the tank it should not be dragged or abraded and folds should be made at
different places each time. Be particularly careful with fork-lifts. The tank should be
rolled onto the forks rather than sliding the forks under the tank.
•
The tank site should be arranged so that it is not sitting in water. A ditch around the tank
will allow water to collect below the tank pad. In hot, sunny areas, shading or a sun
shield will keep UV radiation from the tank and keep the tank cooler, extending its life
span.
•
Fabric tanks are affected more by some liquids than by others. Contact SEI Industries for
information on the effect of the liquid you intend to store.

Maintenance Procedures
Section 7: Maintenance and Minor
Section 7: Maintenance and Minor Repair
Maintenance Procedures
Inspecting Tanks in Service
Frequent inspections of the tank assembly should be made to detect any evidence of leakage. This will permit repairs to be made while the damaged area is small in size. The tank surface should be frequently inspected for any accumulation of debris and spilled liquids.
Caution
When rolling or folding tank, avoid sharp creases. Avoid kneeling or walking on a folded or rolled
tank.
Important Note
Accumulated water or snow should be removed from the top of the HIPPO Frac Tank at the earliest
possible convenience, especially when the snow is wet. Do not allow dry snow to accumulate
more then 76 cm (30") high. Wet snow, slush and ice should be removed immediately; any accumulation of more than 15 cm (6") can potentially force liquid out of the tank vent.
Sealing Small Leaks
Any time an abrasion is found that exposes the scrim (white cloth type fabric), a patch should be applied as
soon as possible (see Permanent Repair in this manual).

Before commencing repairs using glue, the following should be noted:
• The weather should be warm (above 60 deg. F or 15 deg. C) and dry.
• If the glue and patch are not properly placed, air bubbles will be created between the
glue and patch.
• The patch should be weighed down for 8-12 hours.
• The repaired item should not be used before the glue has set.

Section 7: Maintenance and Minor
Important Note
Dura-Seal glue has been designed specifically for the SEI family of fabrics. The shelf life of this
adhesive is about one year. Fresh adhesive can be obtained directly from SEI Industries Ltd.
Warning
Glue vapours are highly explosive! Explosive vapours may occur causing fire and/or injury. Keep
away from all sparks, flame, lighters or cigarettes.
Solvent and glue are both extremely hazardous. Use solvent and glue under well ventilated
conditions only.
When using a warm air fan, either use one which is rated EXPLOSION PROOF or make sure that
there is a steady flow of air past the work area to remove fumes as they are generated.
Repairing in High Humidity
In conditions of high humidity, a proper technique is essential for securing the bond strength desired as the
presence of surface moisture can destroy the effectiveness of the cemented bond.
The evaporation of solvent from the adhesive may reduce the surface temperature below the dew point
resulting in condensation of water vapour on the surface of the adhesive. This is often visible as fogging or
a milky white appearance on the surface.
The use of a solvent to clean the surface prior to cementing can also reduce temperatures below the dew
point.
To overcome the high humidity problem, raise the temperature of the patch area. This can be accomplished
with a warm air fan.

Permanent Repairs
Section 7: Maintenance and Minor
Applying the Glue
Small scrapes, damaged fabric coating or pinholes, which are not leaking, can be repaired with glue only.
They do not require a patch. (A small scrape is defined as damage to the outer fabric coating only. A pinhole
is defined as a small puncture that is not leaking.) However, damage to the base fabric must be repaired with
a patch.
1.
FILL the weight bag with water prior to
beginning repairs.
2.
CLEAN the area to be repaired with an
abrasive pad dampened with solvent.
Remove all traces of masking tape, if
previously used. If possible, place a
piece of masking tape on the back side of
the item being repaired.
Apply masking tape on the backside of tear.
3.
PAINT the damaged area with glue. Use
a thick coat of glue, overlapping the
edges of the repair by 1" (25 mm). Be
sure that the edges are well coated. A
damaged coating should be given two
coats of glue. Apply the second coat
within four hours of the first coat.
Squeeze glue around tear and spread with fingers.
Important Note
Allow repair to harden for 24 hours at room temperature before using the item.
HIPPO Frac Tank Operations Manual (Version B)

Section 7: Maintenance and Minor
Permanent Repairs
Gluing with Patches
If liquid is escaping or there is dampness around the damaged area, the item must be drained. If the damaged
area is still dry, it will be possible to obtain a good bond without draining the item.
Any loose coating should be cut back with scissors. Trim to a point where there is a solid bond between the
reinforcing fabric or scrim and the coating.
1.
SUPPORT THE DAMAGED AREA on a flat, solid platform. If the item is drained, the damaged
area should be supported above the rest of the item. This allows residual liquid to drain away from
the damaged area. This platform should be strong enough to support the fabric (flat) and allow the
patch to be rolled once it is in place.
The damaged
area should
be supported
on a flat, solid
platform.
2.
SCRUB THE DAMAGED AREA with
an abrasive pad dampened with solvent
(isopropyl rubbing alcohol is recommended). Scrub vigorously to remove
the cured surface. The area should be
clean and dry with a dull matte finish.
HIPPO Frac Tank Operations Manual (Version B)
25
Permanent Repairs
Section 7: Maintenance and Minor
Caution
Solvent will damage the fabric if too much is used or if the fabric is left exposed to solvent residue.
3.
Wipe with a rag, dampened with solvent, to remove any residue from cleaning. Check to see if the
area is totally clean and all coated surfaces and edges are dull. If not, repeat the cleaning. This is
critical for a good glue bond.
Cutting the Patch
1.
CUT A PATCH. The patch should be at
least 2" (50 mm) larger in every direction
from the damaged area. A round patch is
recommended but, if a rectangular patch
covers the damage better, then round all corners.
The color of patch will vary, depending on the
product repair kit.
2.
CLEAN THE PATCH by scrubbing with a
pad dampened with solvent. Rub vigorously
to remove the gloss from the fabric. Clean
both sides of the patch, as it is easy to get the
patch turned over during installation. The
patch should also be cleaned on the outside
since it will be painted with glue later.
HIPPO Frac Tank Operations Manual (Version B)
26
Section 7: Maintenance and Minor
Permanent Repairs
Applying the Patch
1.
APPLY THE DURA-SEAL GLUE to the patch and damaged area. WAIT 30 MINUTES (at 75
deg. F or 22 deg. C) for some of the solvent to evaporate from the glue. The glue should become
thicker but still be quite wet. If it has been allowed to dry too long, give both sides another thin
coat. If the glue has dried too long, it will be difficult to avoid entrapping air bubbles in the
bonded joint.
2.
PLACE THE PATCH AND ROLL IT DOWN
with the roller. Place the centre of the patch
down first, then roll it out towards the edges
with the roller. This expels trapped air. Once
the patch is rolled down, do not let it lift up.
This will prevent air from getting under the
patch which causes a weak bond.
3.
If the item is sloped during the repair, TAPE THE PATCH IN PLACE while holding it down. This
stops the patch from sliding away from the damaged area.
4.
WEIGH DOWN THE PATCH. Place a plastic
cover sheet over the patch followed by a
weight bag for 12 hours at room temperature.
The item can then be moved but should not be
filled until the glue has cured for 24 hours.
The weight bag should hold the patch tight
against the item while the glue sets. The plastic cover sheet will prevent the glue from sticking to the weight bag.
5.
If the patch will be subjected to abrasion after 24 hours, paint over the patch with glue. Painting
the patch also provides protection from ultra violet light and weather. Allow the bond to harden
for 24 hours at room temperature before using the item.

Emergency/Temporary Repairs
Section 7: Maintenance and Minor
Using Other Glues
If you do not have any Dura-Seal available, there are two other glues that can be used and are typically easy
to purchase locally.
1.
Loctite 495 can be used on Chem-Shield fabric to provide a quick patch repair but it will make a
long term repair difficult at a later date as all 495 glue must be removed before applying DuraSeal. This can prove to be a time-consuming, stubborn task.
Warning
Loctite 495 carries the following warning. Irritating by inhalation. Eye irritant. Combustible
liquid. Contains cyanoacrilate ester which may cause allergic skin reactions. Skin contact through
clothing may cause burns. Use adequate ventilation in case of eye or body contact. Flush with
water. Get medical attention for eye or internal contact.
2.
The other glue option is 3M’s 420 glue which has the advantage of creating a more permanent
repair. If using this glue, follow the same instructions in this manual as for Dura-Seal adhesive.
Emergency/Temporary Repairs
If you plan on making a temporary repair, which should only be done for emergency circumstances, with a
clamp or wooden screw, then you must line up the outer tank into the same position as the inner tank. This
can be done by placing a small hard object over the leak in the inner tank and holding it in place with some
tape. Next, stretch the outer tank out. Once it is laid flat and lined up with the inner tank, locate the hard
object.
If you are going to use a wooden screw for the repair, follow the instructions below but, because you have
a two layer tank, you will have make the hole in the outer tank slightly larger (about 1/8 of an inch (3mm)
to allow the screw to seal the inner tank and outer tank at the same time.
Caution
Do not use a wooden screw to repair the outer tank only as the screw could cause damage to the
inner tank. Use a patch and glue.
HIPPO Frac Tank Operations Manual (Version B)
28
Emergency/Temporary Repairs
Section 7: Maintenance and Minor
Using a Wooden Screw
Tools and Materials Required
•
Wooden screw
•
Small knife
Small holes that are leaking may be temporarily
plugged using a threaded wooden screw which is
provided in the repair kit. Simply insert the plug
into the hole, turning clockwise until the plug is
tight and the item stops leaking.
Wooden screws can be used to temporarily repair
minor leaks.
Important Note
The wooden screw method is best used on "round-shaped" holes. If the tear is "slit-shaped" then
use a knife to make the opening more round. By making the tear more round, you will not damage
the fabric as much and you will have less to trim when making permanent repairs.
1.
INSERT the screw and turn clockwise
until tight.
2.
The screw should be REMOVED, once
the container is empty, and once you are
ready to make permanent repairs using
glue.
HIPPO Frac Tank Operations Manual (Version B)
29
Emergency/Temporary Repairs
Section 7: Maintenance and Minor
Using Sealing Clamps
If the temporary repair is going to be with a clamp, the clamp must capture the outer and inner tank. If both
are leaking, we don’t recommend using a clamp for the outer tank only. It is better to use a patch and glue
for the repair. Follow the instructions below. The outer tank hole should be about a ¼ inch (6mm) larger
than the inner tank hole.
Tools and Materials Required
•
Clamp (correct size needed)
•
Small knife
Repair clamps are used for an emergency repair to prevent the loss of liquid through large rips or holes up
to 6" in size. For example, if a vehicle accidentally backed into a item and caused a 3" (76 mm) long rip, a
repair clamp could be inserted to stop the loss of liquid.
Repair clamps are only used for temporary repairs. The damage should be permanently repaired with a
patch when the item can be emptied.
Important Note
Leaving the string on makes it easier to remove the repair clamp when placing a permanent patch
on the item.
1.
SELECT the largest clamp that will just slip through the hole in the item. The size of cut or hole
will determine the size of the sealing clamp to use.
•
For a cut or hole up to 2" (5 cm), use a 3" (7.6 cm) clamp.
•
For a cut or hole up to 4" (10 cm), use a 5" (12.7 cm) clamp.
•
For a cut or hole up to 6" (15 cm), use a 7.5" (19 cm) clamp.
Caution
If you are repairing a filled tank, use caution if deciding to enlarge the slit to insert a clamp. It is
very easy to make the slit too large.
HIPPO Frac Tank Operations Manual (Version B)
30

Section 7: Maintenance and Minor
2.
Keeping hold of the string, SLIP one half of the
repair clamp through the hole as indicated.
3.
PULL the bolt up through the hole. TURN it until
the clamp lines up with the hole.
4.
PLACE the top of the clamp over the bolt.

Preparation Before Repacking
•
Empty all liquid from the tank. If the fill/drain fitting is at a low point, capping the vent
and pumping out the liquid will cause the tank to flatten out due to the pump suction.
•
Remove fittings and apply tape over openings to keep dirt out. If it is impossible to
remove fittings, they must be very well padded with sacking to prevent chafing when the
tank is folded.

4.
Once the tank is folded into a flat sausage-shape, fold over one end to keep the tank from unrolling. Tie the tank with the designated straps as seen in the photo below to prevent the folded tank
from shifting.
5.
Finally, tie the completely folded tank with a large rope or webbing to keep it secured. The tank
should be lifted or rolled, never dragged. Tanks can easily be damaged by forklifts or by dragging
them over sharp edges or objects.
HIPPO Frac Tank Operations Manual (Version B)
35
Repacking the Tank
Section 8: Repacking for Storage
Storing the Tank
For best storage life, the tank should be stored in depot-conditions in a cool, dry location out of direct sunlight. SEI Industries defines depot-conditions as a dry, indoor environment with relatively even temperatures between 10o C (50o F) and 43o C (110o F) and low humidity of 50-70%. Lower humidity is preferred
to help extend the tank’s life span.
Important Note
Biocide may be added to the tank to prevent algae growth during storage.
Shipping Instructions
Do not attempt to move the tank when it is partially filled. The tank should never be shipped with liquid
still inside. To prevent damage, the tank should be shipped in the crate originally supplied or in an equivalent sturdy, well-padded crate.

Using the FTDS
Section 9: Using the FTDS
Section 9: Using the FTDS
Using the FTDS
Overview
One of the biggest challenges facing collapsible tanks are the objections from frac crews who have to roll and unroll the tanks.
Traditionally, with metal frac tanks, crew members only have to
connect a few hoses while the remainder of the tank deployment
is done by truck or crane.
Fortunately, SEI’s HIPPO Frac Tanks offer a small-crew deployment system that limits the use of extra manpower or physical activity to unroll and roll-up the bladder.
Using a bobcat and hydraulic power to roll and unroll a tank, SEI’s
Frac Tank Deployment System (FTDS) drastically reduces crew
effort and allows for easier and faster set-up and knock down
times.
• Unfold and deploy one tank in 7-10 minutes
• Mop-up in 12-15 minutes
Features
• Drastically reduce crew size (two person)
• Prevent injury to crew members
• Reduce abrasion (no dragging of the tank)
• Squeeze excess water out of the tank easily
• Roll tanks smaller and tighter to fit back into reusable crates
• Special harness allows for easy tank folding by one person
• Comes with a universal bobcat mounting plate with hydraulic connections
• Roller bars stay with the tank
• Roller connects to auxiliary hand controls on the bobcat
• Painted in high-visibility orange color
