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 wi ll 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

20'12- "11 -09 2

5 of 8



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 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.

5.2.2 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.

5.2.3 The strength test will be held at a pressure greater than the minimum test pressure. 5.2.4 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.

5.2.5 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 wi ll be conducted. Pressure wi ll be dropped to a level corresponding to the leal< test pressure indicated in the attached Hydrotest Calculation Sheets.

5.3.1 The minimum pressure at the high point shall be 110% of the intended maximum operating pressure.

5.3.2 At the end of the leak test a hold period of two (2) hours is required where no drop in pressure is experienced.

5.3.3 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:

DATE 2012-'1'1-09 REVISION 2 PAGE 6 of8


Appendix A - A3 Sureus Hydrostatic Test Plan Page 7 of 49 ____ , __

SURER US ---•PipellneltJt:.•


• Every 5 minutes between 0-30 minutes • Every 10 minutes between 30-60 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 will 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 required to ensure that the section is sufficiently de-watered.

9.7 No conditioners, chemicals or additives will be used to alter the 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 to the satisfaction of the Enbridge Representative.

Bakken NPS 16 HDD Sections HYDROSTATIC TEST PLAN

Test head assemblies shall comply with all requirements of CSA-Z662 (latest edition). All documentation certifying test head compliance shall be available prior to commencement of testing. Test heads will be welded to the section and the welds will be inspected by NDE prior to filling the section.

3.2 Pumps

3.2.1 Surerus shall ensure that fill and squeeze pumps are adequately sized for the length and diameter of the section to be tested.

3.2.2 Water for the hydrostatic test will be withdrawn from the approved water source (Shepherd's Creek) into tanker trucks and transferred to the test sections according to the details in section 4 below.

3.3 Instrumentation:

3.3.1 Surerus shall supply pressure and temperature recorders and dead weights to provide readings for the test data. The pressure shall be measured in psi or kPa, and the temperature measured in degrees Celsius.


3.3.3 Instrumentation for the test shall be as follows: • Two dual pen temperature/pressure recorders and a digital dead weight will

be located at the fill point. 3.3.4 All measurement equipment shall be certified for accuracy not more than 30 days

prior to commencement of the pressure test. The calibration certificates and current calibration reports shall be maintained on site and included in the turnover package following completion of the 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. 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. The filling operation shall be continuous to prevent air ingress.


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 be maintained as "off-limits" to non-essential personnel. 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 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 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 l1ighpoint shall matcl1 or exceecl this minimum at both the start and the encl ohhe

test, and at no time during the test period shall the pressure at the high point drop below the required minimum.

5.2.3 The minimum duration for the hold period on the combined strength and leal< test is one (1) hour.


Surerus will submit all required test documentation within the turnover package. Temperature and pressure readings shall be recorded as follows:

• Every 5 minutes between 0-30 minutes • Every 10 minutes between 30-60 minutes

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 review prior to commencement of the test. All documentation will be turned over to Enbridge upon completion of testing.

7. Leak Detection

During the leak 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 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.

specifically for this project. A copy of the ERP shall be available in each vehicle used on the project.


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 "Restricted Access".

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 set

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 ensure that all components meet the required ratings.

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 where the risk of exposure to the test fluid exists.

2.1 0. 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. Calibrated temperature recorders, pressure recorders, and deadweights. Calibrated f low meter for preparation of the yield plot wl1ere applicable. Adequate lighting and light towers at all work areas.

DATE 2012-11-·16 REVISION 0 PAGE 3 of 6




Steelman Section

The filling operation shall be continuous to prevent air ingress.


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 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 check, the line and manifold will be bled off, an in line 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 38,000kPa (- 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 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. En bridge shall be responsible for completing all yield plots and associated documents.

5.2.2 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.

5.2.3 The strength test will be held at a pressure greater than the minimum test pressure. 5.2.4 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

DATE 2012-'1'1- '16 REVISION 0 PAGE 4 of6



Bakken Mainline NPS 1 6 HYDROSTATIC TEST PLAN

Steelman Section

during the test period shall the pressure at the high point drop below the required minimum.

5.2.5 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 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, pressunzmg, 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 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.

12, Test Personnel Surerus will utilize the following l<ey personnel to complete pressure testing activities:
