Intended deviations shall be listed by the bidder and sent along with the bid, supported by reasons for the same. Also, the bidder shall categorically confirm that their bid completely complies with the specification except for the deviation listed in the deviation schedule.

3.3

The Bidder shall inspect the work site thoroughly and shall satisfy himself, before submitting his tender as to the nature and extent of the work involved, and in general shall himself obtain all necessary information as to the risks, contingencies and other circumstances which may influence or affect his tender. The bidder must have proper communication and coordination with Installation Manager for smooth functioning.

3.7

Installation Guidelines for Deep Anode Bed  The anode string is to be removed from the shipping crate and laid alongside with the vent pipe. The lower capped end of the vent pipe should be 0.5 m beyond the terminal anode on the string.  The 7-kg bottom weight should be tied to the terminal anode by means of a small plastic line or steel wire. The bottom of the weight should be approximately 3 m below the end of the terminal anode.  The vent pipe, the anode string and the weight are now to be lowered into the borehole. Care must be taken so that the person lowering the anode does not put the load on the cable. For this purpose, the nylon rope supplied along with the anode string must be tied to the end weight and string lowered using this rope.  The protective foam covers are to be removed from the anodes before this.  The anode string and vent pipe bundle is now to be lowered into the borehole. Care must be taken to see that neither the anodes nor the cable rubs against the earth surface or casing head, as this could damage the anode string. Once the anode string and vent pipe are lowered, the electrical cable and nylon rope should be securely tied at the top of the hole.  The carbonaceous backfill is now to be slurried and pumped through the fill pipe into the borehole. Once pumping has commenced it must not be interrupted until all the backfill is in place. By pumping the backfill

Page 2 of 12

  

from the bottom up in a deep anode system, the problem of voids, contamination, poor compaction and poor settling are avoided. The backfill bed should be allowed to settle for 24 hours before the anodes are energized. Additional carbonaceous backfill should be added to maintain the designed active length. The column above the top of the carbonaceous backfill should be filled with non-conductive, non-abrasive permeable backfill material such as sand or fine gravel. The casing above grade must be provided with a cap to protect the installation and provide security from entry. The casing beneath the cap must be ventilated with 6.35-mm diameter drilled holes to prevent accumulation of gases. The vent pipe is also to be terminated below the casing cap. A one-inch diameter bushing with nylon screen should be filled to the top of the vent pipe to prevent insect entry.

3.8

Cathode cable connection with pipeline shall be using Pin brazing method. After connections to the pipes, necessary coating repairs shall be carried out using epoxy-hardner compound. Cable specification and size shall be as mentioned in the drawing with stranded copper conductor and armoured.

3.9

All cables shall be laid under ground at a minimum depth of 75 cm and protected by 15cm-sand cushion and width wise laying of bricks at top. Suitable size G.I. pipe shall be provided at all road and drain crossings. Road and drain crossings may be undertaken either by open cut or by boring. Necessary surface restoration after laying of cable shall be carried out.

3.10 Earthing shall be as per IS 3043, latest amendment. All equipment operating at 230V, 50 Hz shall be provided with 1 No individual earth connection each and equipment operating at medium voltage shall be provided with 2 Nos individual earth connection each. 3.11 Earth pits (if mentioned in SOR) shall be made at the boundary of the CPTR foundation. The electrodes of these earth pits, which shall be 75 mm dia galvanised Iron perforated pipes, shall be interconnected with G.I. strip of dimension 50mm X 4mm. The earth pit shall use a combination of charcoal and bentonite for better electrical conductivity. At the ground level, the earth pit shall be enclosed on all sides with 50 mm x 50 mm x 125 mm brick work and covered with a RCC slab. 3.12 Logging of Natural, ON and Instant OFF Pipe-to-soil potential. The procedure for the survey shall be as follows  Logging of corrosion/natural potential before connecting galvanic anodes or before energising the ICCP system of the pipeline.  Switching ON of the ICCP stations.  Allowing a minimum of 168 Hrs (7 Days) time for polarisation of the pipelines.  Installation of GPS synchronised current interrupters.  Synchronisation of all CP stations affecting section of pipeline under test. The setting of the interrupters shall be - OFF cycle = 600 mS and ON cycle = 8000 mS.  Setting the drainage point PSP to (-) 1100 mV instant OFF, w.r.t copper-copper sulphate half cell.  Logging of ON and Instant OFF PSP at all TLPs, Valves, Cased crossings etc. Procedure for measurement of ON and Instant OFF potential : 3 Nos. GPS synchronized current interrupter, asymmetrically switching at 8000 mS ON and 600 mS OFF shall be connected in 3 consecutive CP stations. 1 No. The CP station before the 1st interrupter and the CP station after the 3rd interrupter shall be switched OFF to minimize the effect of these CP stations on measurement of the instant OFF readings. The quality of the data generated shall be of highest order and accuracy. OIL shall undertake some random checks in order to ensure the quality of the data generated by the Bidder. Such tests will be undertaken by OIL with equipment and personnel arranged by the Bidder. Such verification will be carried out in the presence of Bidder's representative. In the event of any dispute arising out of quality of data generated through such testing arrangement, OIL reserves the right to reject the entire data generated by the Bidder or accept partially, depending upon the quality of data generated and assessment made by OIL, without any financial responsibility from OIL's side. 3.13 Current Attenuation Test The basic equipment shall consist of a high power low frequency transmitter (4 Hz) and a hand held receiver. The low frequency transmitter signal shall be injected into the pipeline through the Test points. Depending upon the attenuated signal level, if required, temporary connection to the pipeline has to be established for injecting the signal. Accordingly, necessary excavation has to be carried out for exposing the pipeline and coating shall be removed carefully from a small area of 0.15 Sq cm (approx.) of the pipeline surface and required temporary connection suitably made. After completion of the test in that portion, the connection shall be removed and the Page 3 of 12

metallic surface of the pipeline thoroughly cleaned before re-coating with coal tar enamel etc. Back filling shall then be carried out. Before logging the reading, the Test crew shall first locate the exact alignment of the pipeline within the R.O.W (Right of way) to ensure that the receiver is in exact alignment with the pipeline. All readings shall be taken with receiver held at right angles to the pipeline. The current measurement shall be initially done at 20 mtr and then at an interval of 100 mtrs. A current gradient profile and rate of loss of signal profile against distance traversed along the pipeline chainage is to be prepared after completion of each span. Hot spots / poor coating locations are to be adequately illustrated in relation to permanent benchmarks viz. Boundary wall, Test point, OIL marker, Kilometer post etc. so as to facilitate easy identification of the said locations at a subsequent stage during coating repair. Necessary analysis of test data shall be furnished to indicate coating condition for each span.
