This document contains detailed test procedures with associated lists, tables and a customer comment and sign off area in order to verify and document that each test has been carried out successfully and in accordance with the customer specification (FSD). This procedure has been submitted for for client review and approval. FAT will be performed against this document in the presence of the client or the client nominated representatives. Any divergence from the agree requirement (FSD) will be formally advised to the client such that revision of the requirement may be agreed and the FSD and this document are altered accordingly. 1.1
Scope All instruments calibration will be verified during FAT and will be wired to the control panel and a functional test is carried out by simulating process conditions at the field instruments and the results are recorded on Test Record Sheets. Metering Tests will be conducted with the field I/O’s I/O ’s connected connected to the flow computer and reports will be validated against a gainst commercial AGA 8 software. A set of master documentation (Master FAT), drawings and ISS (data sheets) will be made available for the FAT (refer to to Section 1.3). Any discrepancies will be recorded on the Punch List and any document/drawing changes will be marked in the “Master FAT” copy cop y for incorporation to the documents that will be made available at the SAT.

Any test failures will be fully documented and discussed at the daily review. Failures will be evaluated and prioritized according to impact on both further system testing and test schedule time frame. Test schedule shall be modified tto o continue testing on the unaffected unaffected part of the system. Low priority failures failures which cannot be rectified immediately and do not prevent further testing will be revisited at the end of the scheduled test period. Every effort will be made to rectify high priority failures and retest as soon as they have been resolved. 1.3

Introduction This document is the SAT Procedure to Inspect and verify the functionality of the Large Sales Gas Metering Skid and associated control panel pa nel built under (Indicate BI number) located in (Indicate location). This document contains detailed test procedures with associated lists, tables and a customer comment and sign off area in order to verify and document that each test has been carried out successfully and in accordance with the customer specification (FSD). This procedure has been submitted for for client review and approval. SAT will be performed against this document in the presence of the client or the client nominated representatives. Any divergence from the agree requirement (FSD) will be formally advised to the client such that revision of the requirement may be agreed and the FSD and this document are altered accordingly. 1.1
Scope All instruments calibrations were verified during FAT and there is no need to repeat verification during SAT unless six or more months have passed since FAT. FAT Test Record Sheets shall be available during SAT. Metering Tests will be conducted with the field I/O connected connect ed to the flow computer and reports will be validated against commercial AGA 8 software. A set of master documentation (Master SAT), drawings and ISS (data sheets) will be made available for the SAT (refer to Section 1.3). Any discrepancies will be recorded on the Punch List and any document/drawing changes will be marked in the “Master SAT” copy copy to be included in the “As Built” drawings.
1.2
Test Overview The SAT will begin with a full review of o f the system and documentation followed by the inspection of the skid. The goal of the SAT is to check and certify that the system is in compliance with the purchase p urchase order, requisition, specifications and the approved documents. A daily review will be carried out discussing the day’s da y’s test agenda and the previous day’s test activities and issues. The test will follow a structured plan according to this document.

Any test failures will be fully documented and discussed at the th e daily review. Failures will be evaluated and prioritized according to impact on both further system testing and test schedule time frame. frame. Test schedule shall be modified to to continue testing on the unaffected unaffected part of the system. Low priority failures failures which cannot be rectified immediately and do not prevent further testing will be revisited at the end of the scheduled test period. Every effort will be made to rectify high priority failures and retest as soon as they have hav e been resolved. 1.3
Applicable Documents All documents referenced in the SAT Procedure shall be listed. All documents shall have revision revision numbers and publishing publishing date. Documentation which is part of System and/or is needed during SAT shall be available. Specific items typically include User's Manuals, Maintenance Manuals, configuration drawings, connection drawings, database listings, logic drawings, instrumentation loop drawings (ILD), P&IDs.
