HYDROSTATIC TEST PLAN
1. Scope
This document was prepared for the hydrostatic pressure testing of the Enbridge Bakken
Mainline NPS 16 Pipeline Project planned for construction in the summer/fall of 2012
between Steelman, SK and Cromer, MB. The test shall be completed in two (2) underground
sections and two (2) above-ground sections totaling approximately 123,987m in length; the
test section end points are detailed within the document below. For the below-ground
sections the hydrostatic test consists of a minimum 4.25 hour strength and a minimum 4.25
hour leak test to verify the integrity of the pipeline following installation. At the pipeline end
points, the Steelman and Cromer terminal tie-ins, short sections of the pipeline will be tested
prior to installation due to access restrictions, these segments will be tested for a minimum
period of one (1) hour to permit visual inspection of the pipeline during a combined strength
and leak test.

4.2 Fill section
Test heads will be welded onto the ends of each test section and will be
inspected by NDE. NDE documentation shall be retained to support acceptability
of the welds.
The foreman shall inspect all connections and hoses prior to filling the section.
Prior to filling the pipeline, the fill line shall be leak tested for a minimum of 5min
at 3,450kPa (- 500psi).
To ensure a consistent fill Surerus will monitor and control pressure at the
section end during fill. A pre-pack of compressed air will be established to offset
the head pressure due to the water column during the line fill; this backpressure
will be maintained throughout the fill at a pressure corresponding to the
anticipated water pressure according to the elevation profile. The backpressure
is anticipated to vary between 345 to 1,250Kpa (-50 to 180psi) throughout the
line fill process.
A single medium density pig will be pre-loaded into the test head and will be
driven through the pipeline by the rate of the fluid insertion.
Water shall be pumped from the Alameda Reservoir near the HOD exit location
and transferred via fill line to the section fill points at KP35+500. Enbridge shall
be responsible for obtaining all required water withdrawal permits.
Water shall be left in the pipeline at a pressure of approximately 25% of the
maximum test pressure during a stabilization period to ensure that a consistent
temperature is achieved.
During the line fill process fluid samples shall be obtained by Enbridge
Representatives and submitted for analysis as required.
The filling operation shall be continuous to prevent air ingress.
4.3 Pressurize and test the section.
Before pressurizing the section beyond a pressure of 2,760kPa, all work crews
will be notified and removed from the vicinity of the test section .
All pipe and fill connections shall be checked for leaks and these test areas shall
be maintained as "off-limits" to non-essential personnel.
Pressure will be increased to 2,760kPa and all visible piping inspected for leaks.
Upon completion of the leak checl<, the line and manifold will be bled off, an inline
check valve installed on the squeeze line and the squeeze pump connected to
the line.
Squeeze pressure will be initiated through a 1" or 2· line rated to 38,00QI(Pa
(-5,500psi) ; pressure shall be increased in stages as indicated in the Hydrostatic
Test Record Worksheets.
5. Test Stages
The pipeline shall be tested in the following stages:
e
Leak check
e
Strength test (including yield plot where required)
e
Leal< test
DATE
REVISION

Page 6 of 49
5.1. Leak Check
The first stage involves a leal< check at approximately 2, 7601<Pa to allow visual inspection of
exposed piping and fittings included in the test section. Any pressure lost during this period
must be explained to the satisfaction of the Company's testing supervisor prior to
pressurizing to the target strength test pressure
5.2. Strength Test
Following satisfactory completion of the leak checl<, testing will continue by slowly raising the
pressure to the strength test pressure as indicated in the attached Hydrotest Calculation
Worksheets. The strength test will be held at a pressure greater than the minimum test
pressure.
5.2.1
5.2.2
5.2.3
5.2.4
5.2.5
Yield plotting, if required, shall be undertaken as the section is pressurized during the
strength test. Yield plotting shall commence at a pressure equivalent to 60% of the
maximum anticipated test pressure . Yield plotting shall only be required where the
expected maximum hoop stress in the test section during the strength test is greater
than 100% SMYS of the pipe. Enbridge shall be responsible for completing all yield
plots and associated documents.
Pumping shall continue until the selected strength test pressure is achieved or, where
a yield plot is required, the point where the yield plot deviates beyond the 0.2% offset
line.
The strength test will be held at a pressure greater than the minimum test pressure.
After pumping has ceased, and the selected strength test pressure has been
reached, the strength test will commence. The pressure at the highpoint shall match
or exceed this minimum at both the start and the end of the test, and at no time
during the test period shall the pressure at the high point drop below the required
minimum.
The minimum duration for the hold period on the strength test is four and a quarter
(4.25) hours.
5.3. Lealt Test
After successful completion of the strength test, a minimum four and a quarter (4.25) hour
leal< test will be conducted. Pressure will be dropped to a level corresponding to the leal< test
pressure indicated in the attached Hydrotest Calculation Sheets.
5.3.1
5.3.2
5.3.3
The minimum pressure at the high point shall be 110% of the intended maximum
operating pressure.
At the end of the leak test a hold period of two (2) hours is required where no drop in
pressure is experienced.
The test duration may be extended beyond the four (4) hour period to achieve these
requirements.
6. Test Documentation
Surerus will submit all required test doCLrmentation within the turnover package. Temperature
and pressure readings shall be recorded as follows:

Every 5 minutes between 0-30 minutes
Every 15 minutes for the remainder of the test
Records shall include the start and stop times for any pumping, pressunzrng, or depressurizing of the test section. A copy of the test worksheet shall be made available for
review prior to commencement of the test. All documentation will be turned over to Enbridge
upon completion of testing to facilitate completion of required Leave To Open applications.
7. Leak Detection
During the leal< test, any drop in pressure which cannot be correlated to a change in
temperature shall be considered a leak. If a leak is suspected Surerus shall notify the
Enbridge Representative and further pressurizing of the pipeline shall be halted until the
source of the leak can be determined. Should any failure require repair, the line pressure
shall be reduced to static pressure, the section dewatered, and the repair completed.
8. Depressurizing
Upon the completion of a successful test, the pipeline w ill be depressurized slowly until the
energy has reached an acceptable level prior to dewatering. The line will be depressurized
into a pressure trucl< rated in excess of the maximum test pressure. Under no circumstances
will valves be moved to the full open position to initiate depressurizing. The maximum
depressurizing rate shall be equal to 200kPa/min.
9. Dewatering
9.1 All test water shall be disposed of in accordance with applicable regulations.
9.2 Upon successful testing of the sections the water will be discharged by means of a
controlled land release in the vicinity of KP 35+500 near the water source. Water
discharge volumes correspond to the section volumes. Enbridge shall secure all
necessary permits for the discharge of hydrostatic test water.
9.3 Lines will be securely fastened and supported to prevent "whipping" or sudden
releases of energy during the dewater or water transfer process.
9.4 A high density coated poly pig or bi-directional multi-disc pig propelled by
compressed air will be used for dewatering.
9.5 Surerus w ill utilize additional pigs for de-watering if insufficient volumes of f luid are
received at the release point of the section during initial de-water activities.
9.6 Additional runs will be performed as requ ired to ensure that the section is sufficiently
de-watered.
9.7 No conditioners, chemicals or additives will be used to alter t he natural quality of the
water at any point during the hydro test
9.8 Water shall be discharged into a diffuser and then directed through filter cloth to
prevent erosion at the dewater location.
1 0. Pig/Cleaning Runs
'10.1 Following completion of testing of each section, multiple dewatering runs shall be
completed to remove any free-standing water within the pipe section
satisfaction of the Enbridge Representative.

4.2 Fill section
Test heads will be welded onto the ends of each test section and will be
inspected by NDE. NDE documentation shall be retained to support acceptability
of the welds.
Prior to filling the pipeline, the fill line shall be leak tested for a minimum of 5min
at 3,450kPa (500psi).
To ensure a consistent fill Surerus will monitor and control pressure at the
section end during fill. Surerus does not anticipate that a pre-pack of the line is
required due to the minimal elevation difference throughout the test section.
A single medium density pig will be pre-loaded into the test head and will be
driven through the pipeline by the rate of the fluid insertion.
During the line fill process fluid samples shall be obtained by Enbridge
Representatives and submitted for analysis as required.
Before pressurizing the section beyond a pressure of 2, 760kPa (400 psi), all
worl< crews will be notified and removed from the vicinity of the test section.
All pipe and fill connections shall be checked for leaks and these test areas shall
Pressure will be increased to 2,760kPa (400psi) and all visible piping inspected
for leaks.
Upon completion of the leak check, the line and manifold will be bled off, an in line
the line.
Squeeze pressure will be initiated through a 1" or 2" line rated to 5500psi;
pressure shall be increased in stages as indicated in the Hydrostatic Test Record
Worl<sheets.
5. Test Stages
The pipeline shall be tested in a combined '1-hour strength and leak test. The pipe section
will be available for visual inspection throughout the duration of the test.
5.1. Combined One-Hour Strength and Lealt Test
The test involves a leal< check at approximately 2,760kPa (400psi) to allow visual inspection
of e:<posed piping and fittings included in the test section. Following satisfactory completion
of the leak checl<, testing will continue by slowly raising the pressure to the strength test
pressure as indicated in the attached Hydrotest Calculation Worksheets . The strength test
will be held at a pressure greater than the minimum test pressure.
5.2.1 The combined strength and leal< test will be held at a pressure greater than ths
minimum test pressure. The test pressure shall be basecl upon the ma)<imum
anticipated pressure the HDD section will e:<perience during the mainline pressure
test.
5.2.2 After pumping has ceased, and the selected strength test pressure has been
reachecl, the combined strength and leak test will commence. The pressure at the

test, and at no time during the test period shall the pressure at the high point drop
below the required minimum .
The minimum duration for the hold period on the combined strength and leal< test is
one (1) hour.

•
Records shall include the start and stop times for any pumping, pressunzmg, or depressurizing of the test section. A copy of the test worl<sheet shall be made available for
upon completion of testing.
7. Leak Detection
During the leak test, any drop in pressure which cannot be correlated to a change in
source of the leak can be determined. Should any failure require repair, the line pressure
shall be reduced to zero, the section dewatered, and the repair completed.
8. Depressurizing
Upon the completion of a successful test, the HOD section will be depressurized slowly until
the energy has reached an acceptable level prior to dewatering. The line will be
depressLirized into a pressure truck rated in excess of the maximum test pressure. Under no
circumstances will valves be moved to the full open position to initiate depressurizing.
9. Dewatering
9. 'I All test water shall be disposed of in accordance with applicable regulations.
9.2 Upon successful testing of the sections, the water will be discharged by means of a
controlled land release. Water discharge volumes correspond to the section volumes
noted in section 4 of this document. Enbridge shall secure all necessary permits for
the discharge of hydrostatic test water.
9.3 Lines will be securely fastened and supported to prevent "whipping" or sudden
releases of energy during the dewater or water transfer process.
9.4 A high density coated poly pig or bi-directional multi-disc pig propelled by
compressed air will be used for dewatering.
9.5 SLirerus will utilize additional pigs for de-watering if insufficient volumes of fluid are
received at the release point of the section during initial de-water activities.
9.6 Additional runs will be performed as required to ensure that the section is sufficiently
cle-watered.
9.7 No conditioners, chemicals or additives will be used to alter the natural quality of the
vvater ai any point during the hydro test.

1. Scope
This document was prepared for the hydrostatic pressure testing of the En bridge Bakl<en
Mainline NPS 16 Pipeline Project planned for construction in the summer/fall of 2012
between Steelman, SK and Cromer, MB. This test plan encompasses approximately 94m of
pipe from the Steelman terminal eastbound; the test section end points are detailed within th e
document below. The Steelman section of the pipeline will be tested above ground prior to
installation due to access restrictions. The segment will be tested for a minimum period of
one (1) hour to permit visual inspection of the pipeline during a combined strength and leak
test utilizing a water/methanol mix to prevent freezing during testing.
2. Safety
2.1.
specifically for this project. A copy of the ERP shall be available in each vehicle used
on the project.
2.2. A pre-phase meeting will be held at the Surerus site office for all personnel involved in
2.3. Surerus will install warning signs and barricades to prevent access to the vicinity of the
test area. Warning signs shall indicate "DANGER - High Pressure Pipeline Test" and
2.4. All Surerus personnel not involved in the testing shall be removed from the area wh ile
the pipeline section is under a pressure equal to or greater than 2,760kPa (-400psi) .
2.5. Test heads and pressurizing pipe shall be secured to limit movement.
2 .6. All testing equipment including compressors, recorders, deadweights, etc. shall be s et
up a safe distance from the test section and/or test heads.
2.7. Surerus employees shall inspect all hoses, lines, and connections for faults prior to
pressurizing the lines. The Surerus Hydrotest Pre-test Checklist will be completed to
2.8. Surerus personnel shall ensure pressure hoses/unions are rated to twice the maximum
expected hydrotest pressures, and all safety lines are firmly attached and secured with
whip checks.
2.9. Test crews shall review the requirements for working with methanol and wear
appropriate PPE at all times w here the risk of exposure to the test fluid exists.
2.10. An En bridge representative will be on site for the duration of test activities.
3. Equipment
Surerus shall supply the following equipment for completion of the hydrostatic test:
Tanker trucks to transfer test fluid.
Truck-mounted squeeze pump to complete pressure testing.
Air compressor required for pipeline cleaning and dewatering.
All pipeline pigs required for line fill and dewatering.
All necessary valves, hoses, and fittings required to successfully complete the
test.

Before pressurizing the section beyond a pressure of 2,760kPa, all work crews
will be notified and removed from the vicinity of the test section .
All pipe and fill connections shall be checked for leal<s and these test areas shall
Pressure will be increased to 2,760kPa and all visible piping inspected for leaks.
Upon completion of the leak check, the line and manifold will be bled off, an in line
the line.
Squeeze pressure will be initiated through a 1" or 2" line rated to 38,000kPa
(- 5,500psi); pressure shall be increased in stages as indicated in the Hydrostatic
Test Record Worksheets.
5. Test Stages
The pipeline shall be tested in the following stages:
• Leak check
• Combined Strength and Leak test (including yield plot where required.
5.1. Leak Check
The first stage involves a leak checl<at approximately 2,760kPa to allow visual inspection of
exposed piping and fittings included in the test section. Any pressure lost during this period
must be explained to the satisfaction of the Company's testing supervisor prior to
pressurizing to the target strength test pressure
5.2. Combined Strength and Leak Test
The minimum duration for the combined strength and leak test is one (1) hour. Following
satisfactory completion of the leak checl<s, testing will continue by slowly raising the pressure
to the test pressure.
5.2.1
5.2.2
5.2.3
5.2.4
Yield plotting, if required , shall be undertaken as the section is pressurized during the
strength test. Yield plotting shall commence at a pressure equivalent to 60% of the
maximum anticipated test pressure. Yield plotting shall only be required where the
expected maximum hoop stress in the test section during the strength test is greater
than 100% SMYS of the pipe. Enbridge shall be responsible for completing all yield
plots and associated documents.
Pumping shall continue until the selected strength test pressure is achieved or, where
a yield plot is required, the point where the yield plot deviates beyond the 0.2% offset
line.
The strength test will be held at a pressure greater than the minimum test pressure.
After pumping has ceased, and the selected strength test pressure has been
reached, the strength test will commence. The pressure at the highpoint shall match
or e}cceed this minimum at both the start and the end of the test, and at no time

during the test period shall the pressure at the high point drop below the required
minimum.
The minimum duration for the hold period on the strength test is one (1) hour.
Surerus will submit all required test documentation within the turnover package. Temperature

Every 15 minutes for the remainder of the test
Records shall include the start and stop times for any pumping , pressunzmg , or depressurizing of the test section. A copy of the test worksheet shall be made available for
upon completion of testing to facilitate completion of required Leave To Open applications.
7. Leak Detection
During the leal< test, any drop in pressure which cannot be correlated to a change in
source of the leal< can be determined . Should any failure require repair, the line pressure
shall be reduced to static pressure, the section dewatered, and the repair completed.
8. Depressurizing
The line will be depressurized into a pressure truck rated in excess of the maximum test
pressure. Under no circumstances will valves be moved to the full open position to initiate
depressurizing.
9. Dewatering
9.1 Upon completion of the test, the test fluid will be transferred into tanker trucl<s for
disposal.
9.2 All transfer lines will be securely fastened and supported to prevent "whipping" or
sudden releases of energy during the dewater process.
9.3 The pipeline will be dewatered with a high density coated poly pig or bi-directional
multi-disc pig propelled by compressed air.
