  Data Sheets

Reference is made to the forms of Bidder’s Data Sheets of these Specifications. The blank forms contained therein shall be completely filled in and submitted together with the Bid.

       INSPECTION & TESTING                     :   

    The complete Fuel Gas Pipeline and Custody Metering Skid shall be subject to tests and inspection during manufacturing, fabrication, installation, and upon completion to verify compliance with the Contract requirements.

  All appliances and equipment, which are to be used in testing, shall be of written warranty concerning their precision and calibration curves, and shall be approved by a recognized international test laboratory.

All tests shall be carried out to the most advanced standard procedures and testing methods applied.  As much as it is practicable, tests shall be carried out on the equipment, which is fully assembled.

.   After completion of installation, the equipment shall be prepared for operation including commissioning and inspection, to prove the readiness of the supplied equipment and the performance of their function with other equipment.

  Such tests shall be carried out together with the other equipment after the required routine tests.  These works and tests shall include the following:

      -   Functional and operational tests for all the system ancillaries and accessories.
       -  Durability and soundness of all power and control wirings.
      -   Electrical insulation and high voltage tests (at 75% of factory test voltage)
       -  Measurement of grounding system resistance.
-         Preliminary operation tests for the whole assembly.

- The contractor shall provide all equipment and tools necessary for testing.

    The contractor shall give a written one (1) week notice to the Owner/Engineer, to give him the chance to prepare for all site tests, inspections, and examinations to be carried out and attend or observe them.

The Contractor shall bear all costs and expenses of test inside or outside.

       SITE ACCEPTANCE TESTS (SAT)

-     After installation of the system at the site, a Site Acceptance Test (SAT) shall be conducted. The SAT shall basically a repetition of the FAT, but with the system installed in a field environment and all related components, piping, and equipment connected in the final configuration. 

The SAT shall be conducted under actual operating conditions using natural gas.
- The contractor shall prepare an SAT procedure.

 The SAT procedure shall be delivered to the Owner within two (2) weeks before carrying out the SAT for Owner/Engineer’s approval.

 The SAT procedure shall be a detailed item-by-item procedure for the performance of the SAT, which delineates the tests to be performed, both for hardware and for software.

 The SAT procedure shall include checklists covering all inspections, tests, calibration, generation of reports i.e., batch report, and checkout procedures, and shall list acceptance criteria for each phase of the test.

-     The SAT shall be thoroughly and completely documented such that at the conclusion of the SAT, a complete record of each test and its results shall be available.
