14 FLOODING, CLEANING, GAUGING & HYDROSTATIC TESTING 14.1. Test Medium All seawater entering the pipelines shall be free from any debris, sand, silt or air. To achieve this the water shall be fed through a break or settlement tank, and then filtered before being pumped into the pipeline. The filters shall be placed in parallel so they can be cleaned or changed without interrupting operations and shall be capable of removing all particles over 50 microns. The average content of suspended matter shall not exceed 20g/m3. All cleaned test seawater introduced into pipeline shall be chemically treated with corrosion inhibitor, biocide and oxygen scavenger.

Periodic sampling shall be made of the water pumped into the pipeline and an analysis conducted on the sample taken. At least two independent tests of chemically treated fill water shall be taken for each pipeline test section. Chemically treated water is sufficient for one year preservation in the pipeline.

Representative samples shall be taken at commencement and at convenient intervals during line filling and flushing. Frequency and timing of samples shall be at the direction of COMPANY. The analyses shall quantify the following:

1. Oxygen (



The concentration level of each of the chemical additives shall be maintained within 5% of the approved levels. All chemicals shall conform to the written consent for pipelines discharge issued by the relevant Statutory Authorities.

Selection of the type of corrosion inhibitor, oxygen scavenger, biocide and dye shall be considered for possible harmful interactions and their impact on the environment during and after disposal of the water. Where flanges shall be installed in the pipeline test section a dye shall be added to the treated water during the pressure test. Dyes shall be selected from materials that are easily visible underwater. The dosage should be as recommended by the supplier.

14.2. Flooding, Cleaning & Gauging Before filling the pipeline (after pig 4, Gauging Pig), the sea water will be treated to ensure that the quality of the water meets COMPANY requirements. A 50 micron filter will be installed to catch solid particles over 50 microns. Multitreat 5549R will be used as corrosion inhibitor, oxygen scavenger and biocide. Chemical inhibitor, oxygen scavenger, dye will be mixed in tank. Preference of dosage is 700 ppm for the chemical treatment and 15 ppm for the fluorescent dye ( green color ).

Filling water will be injected into the pipeline shall be achieved by using 4 pigs driven by pumped water. The pigs run at 0.5 1.5 m/s. Pressure will be measured by pressure gauge. The volume of the water will be measured by flow meter. The volume of sea water (untreated) in between two pigs is 30 m. Because of the elevation difference along the mainline, a back pressure of 1 bar must be maintained to stabilize the velocity of the pig while water filling. During the filling operation, the volume of seawater pumped into a pipeline shall be enough to achieve a flow velocity in the range 0.5 1.5 m/s . See attachment 10 for Flooding, Cleaning & Gauging calculation.

The pig sequence is pig 1. Flooding pig (Bi-Di normal), pig 2. Bi-Di Brush, pig 3. Bi-Di Magnet, pig 4. Gauging pig (Bi-Di Gauging). Pingers will be installed on pig 1 and 4, as leading and trailing pigs and tracked on the receiver ( Palang Land Fall ).

This Step shall be conducted by the following sequence: see attachment-2 (Flooding, Cleaning & Gauging).

1. The Laydown head shall be pre-loaded with four bi-directional pig for Flooding, Cleaning & Gauging at location. The laydown head will be attached to the Expansion Spool Flange ( KP 23.3).

The pulling head located at land fall Palang will receive the four pigs. The pulling head was designed to receive the pig train and preparations (include discharge hoses connection to settlement tank and ensuring correct discharge valves status) will be made to vent the line. Preparation will be confirmed prior to pigging operation.

2. Connect the Laydown Head on the seabed to the flexible hose 4 to filling pump onboard the Hafar Neptune (KP 23.3). Diver to secure hose camlock connections by securing a hose tether to pig launcher guard.

3. Connect hose 2 to valve 2, 3, 4 & 5 at pulling head at land fall Palang to vent any air trapped in the mainline and by releasing the water to water tank and water pond. Valve No. 1 installed pressure gauge with 0 600 Psi and open position. Valve no. 6 closed position uses for emergency (pig stall).

4. Open valve no F & E, then turn on the filling pump, insert 10 m of untreated seawater in front of the first pig (Flooding) through valve no. E.

5. Close valve no. E then open valve no. D to start filling water and thus launch the first pig by pumping of untreated seawater 30 m ( distance between pig is 164 m). Leave valve no. F, 2, 3, 4 & 5 in open position to flush out air and water from the mainline to the water tank, valve no. 6, A, B, C & E are in closed position.



6. Then continue to pumping of 30 m untreated seawater for the second pig (Bi-Di Brush) by opening valve no C (distance between pig is 164 m). Leave valve no F, 2, 3, 4 & 5 in open position to flush out air and water from the mainline to water tank, valve no 6, A, B, D & E are in closed position.

7. Then continue to pumping of 30 m3 untreated sea water for the third pig (Bi Di Magnetic) by opening valve no B (distance between pig is 164 m). Leave valve no F, 2, 3, 4 & 5 in open position to flush out air and water from the mainline to water tank, valve no 6, A, C, D & E are in closed position

8. Open valve no. A (valves 6, B, C, D & E closed position) Continue with chemically treated sea water filling and send the fourth pig (Bi-Di Gauging) until the mainline is completely filled.

9. Once the Four pigs have arrived at the pulling head / receiver ( land fall Palang), track the gauging pig to ensure the pig have arrived, then close valve no. 4 & 5 slowly and continue water filling.

10. Vent out any air from the pulling head / receiver (land fall Palang) by opening valve no. 2 & 3 . Continue until all air is expelled.

11. All of untreated sea water (10 m of water in front of the first pig, 30 m of water between of first pig and second pig, 30 m of water between of second pig and third pig, 30 m3 of water between of third pig and fourth pig) was released while venting will be collected in water pond through water tank for treatment. Air Compressor supply Oxygen to the water pond. The water returned to the sea after an analysis conducted on the Laboratory ( PT Envilab Indonesia) and meets the waste water standard

12. Once the pigging operation has been completed, remove the pulling head / receiver ( land fall Palang) and analyze the result of the gauging pig. Then weld on a WN Flange to pipeline.. Refer to attachment 17 for pull head/ receiver removal, weld neck flange aand test blind installation sequence.

During filling operation, the following data shall be recorded every 15 minutes: Time of departure and arrival bi-di pigs. Flow and water in m3. Inlet and outlet pressure. Acceptance Criteria Cleaning is considered to be completed when the quantity of debris does not exceed 1% of the total pipeline volume during a single pipe cleaning run. In case higher solid contents are found additional pig should be run until pipeline is cleaned from the debris. Sample water will be taken between 3rd & 4th pig arrival, and put into 3 x 1 ltr clear graduated measuring cup. The water then will be sieved through 50 micron filter. The collected debris will be weighed, and then divided by specific weight of steel (7.82 kg/ltr), to get the volume of the debris. The pipeline will be deemed clean if:

(Volume of debris / Volume of water) x 100% 1%

Note: If sample completed does not satisfy above requirement, 3 more water samples will be collected after the 4th pig. Average results of the collected water samples will be used.

The gauge plate is to be made of 6 mm aluminium plate with a gauge plate diameter of 95% of the lines internal diameter. The damage OD gauge plate should not be less than 95% of minimum pipeline ID or 25mm less than minimum pipeline ID whichever is larger.



14.3. Hydrostatic Testing

14.3.1 Pressurization

High Pressure Pump (at land fall Palang) connect fittings onto the test manifold (Palang Land Fall) See attachment- 4 (Hydrotest Arrangement) and attachment 17 for weld neck flange and test blind installation. Ensure that all connections are connected and correctly tightened. All the pressure hoses will be secured using whip line before start up of pressurization.

4. Close valve no. 5 and open valve no 1, 2, 3, & 4 then turn on High Pressure Pump for starting pressurization. (Refer to attachment 4)

5. The pressurization will be conducted by the following pressurization step, as follow:

a) Pressurize 5.7% (96.3 psi) to 50% of the test pressure.



The pressure increase rate shall not exceed 14.5 psi/min. When the pressure reaches 50% of the test pressure (844 psi), stop the pump 30 minutes for stabilization, ensure no leaks exist and perform air entrapment calculations if necessary. During this period, monitor the pressure and check the test section for leakage. If a leak is found, depressurize and dewater the pipeline if necessary and repair leaks.

b) Pressurize 50% to 75% of the test pressure

If no leak is found continue pressurization to 75% of the test pressure (1266 psi). The pressure increase rate shall not exceed 11.6 psi/min. Stop the pump 30 minutes for stabilization and ensure that no leaks exist.

c) Pressurize 75% to 95% of the test pressure

Continue pressurization to 95% of the test pressure (1604 psi). Slow the pressurization rate down to 7.3 psi/min. Stop the pump 30 minutes for stabilization and ensure that no leaks exist.

d) Pressurize 95% to 100% of the test pressure

After 30 minutes stabilization at 95% of test pressure, resume the pressurization. During this final phase of pressurizing, the pressure increment shall not exceed 1.5 psi/min until reaching 100% of test pressure (1688 psi). Stabilize the pressure for 24 hours prior to start the holding time. When the test pressure is reached, the filling valve shall be closed and the pressurizing line shall be disconnected from the valve on the test header. CONTRACTOR shall perform the trapped air calculation before start of holding time.

14.3.2 Holding Time of Pressure Test

After attaining the test pressure, the line shall be left for 24 hours to stabilize. Final pressure in the line shall be noted from the dead weight tester and held for 24 hours

minimum. Check and report pressure and temperature from Barton chart, pressure gauge, temperature

gauge and DWT every 15 minute. Sub Sea temperature gauge will be installed at the land fall Palang Atmospheric temperature shall be recorded at regular intervals.

14.3.3 Entrapped Air Calculation Prior to start-up of test activities, the Hydrostatic Engineer should perform a pre-test calculation of obtain a theoretical value of DV/DP for the verified volume of pipe under test and the appropriate test medium . This information to be used to determine whether entrained gas exist in the line under test. DV/DP is defined as the change in volume for an associated change in pressure of a known volume under pressure.

14.3.3.1 Theoretical Value A theoretical V/P will give the expected volume change for an associated change in pressure for the specified volume under test assuming that the volume under pressure is free



of entrained gas. The theoretical V/P for buried (restrained) pipe is calculated through the following equitation :

1

1

Where,

v = Incremental Volume (m3) p = Incremental pressure (bar) V = Pipeline volume (m3)

D = Pipeline outside diameter (m)

t = Nominal wall thickness (m)

E = Youngs elastic modulus of steel = 2.07 x 106 bar

= Poissons Ratio = 0.3

B = Bulk modulus of seawater (bar)

14.3.3.2 The Field Value A field of DV/DP is the actual volume change for an associated change in pressure for the specified volume under test. If air exists within the line under pressure, this value will be different that the theoretical value. This procedure provides guidelines for calculating both DV/DPs and acceptable differences between the theoretical and field values of DV/DP.

a) Obtaining Field DV/DP During initial pressurization, the test section shall be pressurized to 1688 psi and allowed to stabilize. Take an accurate pressure reading. Then bleed approximately 10 psi and allow the test section to stabilize. Take another accurate pressure reading. Carefully, measure the volume of the fluid that was bled and convert this to gallons if necessary. Take the volume bled and divide this number by the difference in the pressure readings. This is the field value of DV/DP. b) Acceptable DV/DP Result of value DV/DP shall be compared with the theoretical value of DV/DP calculated. A field value of DV/DP that is greater than the theoretical DV/DP indicates the presence of entrapped air or other gas in the pipe section. So, air or other gas should be vented at the test header end, before starting the test. Acceptance Criteria (field DV/DP) (theoretical DV/DP)



14.3.4 Acceptance Criteria

A successful test shall consist of a twenty four (24) hours hold period in which the test pressure was held, with no unaccountable pressure decrease. Should a leak occurs, the pipeline shall be repaired and the hydrostatic test repeated. The CONTACTOR shall keep complete records of failures occurring during the test, including

the exact locations, type and cause of failure, and method of repair. Pipe fittings and valves that fail and are replaced shall be marked with their pipeline locations and the pressure at which they failed.

Pressure drops because of improper stabilization prior the holding time period shall lead to extensions of the holding period by multiples of four-hour periods. No pressure drops shall be acceptable during the test period, except if those clearly attribute to temperature changes or other environmental effects.

For buried pipeline, pressure test is acceptable if the pipeline is free from leaks and pressure variation is within 0.2% of test pressure is over the agreed 24 hours hold period.

Test duration shall be increased in case of any abrupt change in atmospheric conditions.

14.3.5 Depressurization

When the testing is completed and accepted by COMPANY, depressurization shall be started by the following:

a) Depressurization will be performed at the launcher (land fall Palang) by draining the water

Depressurize 100% to 75% of the test pressure, rate 14.5 psi/min, and hold 15 minutes. b) Depressurize 75% to 50% of the test pressure, rate 29.0 psi/min, and hold 15 minutes. c) Depressurize 50% to 30% (50.8 psi) of the test pressure; rate 43.5 psi/min Pressure 50.8

psi will be kept in the line for back pressure the dewatering activities.

Depressurization will be performed at the end test header by draining the water through opening valve no. 5 which will installed the hose to water tank. All water released while depressurizing will be collected into a water tank and then to water pond for treatment.

15 TEST DOCUMENT The CONTRACTOR QC Inspector shall prepare and submit the document and report related to hydrostatic testing operation such as; pressure report and record chart etc.

Attachment 1Contingency Plan

CONTINGENCY PLAN1. INTRODUCTION

Sometime due to many reason the pig might not arrive at the receiver during pig operation. If thishappens this work instruction could be applied to recover the pig. Include snapped hose and sea waterentering/flooding pipeline.

2. HAZARDSVenting causing hearing damage and offensive noise in the local area, damage to valve seats and trims,respiratory damage due to airborne particles.

3. JOB STEPS3.1. Non Arrival Pig

This procedure is applicable to recover a pig that has not arrived yet.

1. Operation notifies that pig has not arrived yet. Pig arrival time is overdue 25% from calculation.

2. Check launch site. If the pig is still in the launcher, re-launch the pig. If the pig is not in launcher,check flow rate and pressures

3. If flow rate are normal, the pig is bypassing. Go to section 3.2 (A) of Stall Pig. If flow rate is zero,check differential pressure. If flow rate has changed, re-calculate travel time. If pig travel time is notoverdue then continue pigging process. If pig travel time is overdue, check differential pressure.

4. Checking differential pressure

If differential pressure is high, please check receiver. There is possibility that there is debris inreceiver. If differential pressure is low please check possibility of process problem. If there is processproblem continue pigging activity. If there is no problem in process, please check the receiver side fordebris accumulation.

Confirmed Stall/Pig StuckThis procedure is applicable to recover the pig that is confirmed stalled.

A. If product bypass occurred1. When the pig is confirmed stall, identify if there is product bypass (indicated by almost normal

pressure and flow rate). In this case, try to increase pressure and flow rate to push the pig.

2. If pig still stall, try to re-pumping from receiver

3. If the pig starts to move, continue pigging operation.

4. If you can identify that the pig is moving, continue pigging operation. If the pig doesnt move at all,you may see pressure built up. Go to step B of this section 3.2.

B. If no product bypass occurred1. If the product is not bypassing, you will see indication of pressure built up. It is expected that the pig

moves. If the pig moves, continue pigging process. If the pig does not move try to do rocking.

2. Do rocking or increase pressure at launch site and reduce pressure at receiver instantly a coupletimes and pressure not more than 200 psi . Check pig movement. If pig moves, continue piggingoperation. If pig does not move try to push the pig backward a bit then push again to receiver.

3. If the pig can move, continue pigging operation.

4. The equipment used for increasing pumping pressure in the event of a stuck pig willbe the same, just that both filling pumps will be operated simultaneously instead ofone filling pump. If there is a need to push the pig backward, the filling pumps will bedeployed in the same setup on Palang land fall. Refer to attachment 2 & 3.
