Instrument completion documents

Reference standards: SH/T 3521-2013 – Technical Specifications for the Construction of Petrochemical Instrumentation Projects; SH/T 3551-2013 – Quality Acceptance Criteria for the Construction of Petrochemical Instrumentation Projects. I’m not aware of the scale of your project, nor what documents have been prepared by the design institute. If all the necessary documents have been provided by the design institute, then upon project completion it will be necessary to submit documents such as an I/O point list, a DCS data sheet, or a DCS communication point list. Additionally, one set each of circuit testing records, interlock testing records, and instrument calibration records is required. There’s also one set each of the instrument specifications, DCS programs, and instrument inventory lists. That’s roughly all

The documentation related to DCS is relatively complete; what’s needed mainly are the completion documents for the instruments that require approval from external authorities

Approval processes vary by region; each area has different requirements for completion documents. As for the instrumentation aspect, these are the main points I mentioned. If all the design documents and commissioning records are complete, the expert team will approve it after reviewing them……

Different factories have different requirements. Generally, the general contractor for petrochemical projects provides a table for the evaluation of quality by different components, and the documents must be organized in accordance with the contents of this table. The instruments require various types of data related to petroleum, petrochemicals, and geographical locations; it depends on which standard is in use where you are.

1. The first type consists of complete records of individual instrument calibration, including random or full inspections of temperature sensors (depending on the requirements of the project). 2. Records of circuit calibration (for various types of detection circuits). 3. Calibration of control circuits. 4. Records of pressure testing for pressure acquisition pipelines. 5. Records of pressure testing for valves. 6. Records of panel and cabinet installation. 7. Records of wire routing, especially those related to concealed pipelines. 8. Records of calibration of alarm and interlock devices. 9. Records of flow meter installation. 10. Records of DCS and PLC setup, etc. Of course, as-built drawings are the most essential and important documents.

The Technical Equipment Department should participate in or organize activities related to the completion inspection, commissioning, and transfer of completion documents for instrument and equipment projects (refer to the standards \"Specifications for the Construction and Acceptance of Automated Instrumentation Projects\" and \"Technical Specifications for the Construction of Petrochemical Instrumentation Projects\"). To ensure that the completion documents are complete, they should include: 5.6.1 The as-built drawings of the project shall comprise the complete set of design drawings for the instrumentation and automatic control systems, as well as the as-built drawings ； 5.6.2 Design modification documents and material substitution documents ； 5.6.3 Documentation and records of concealed works ； 5.6.4 Ground resistance test records ； 5.6.5 Instrument Installation and Quality Inspection Records ； 5.6.6 Cable insulation test records ； 5.6.7 Records of purging, pressure testing, and leak testing for instrument air and pressure guiding pipes ； 5.6.8 Certificates of product quality for instrumentation equipment and materials ； 5.6.9 Instrument calibration and testing records ； 5.6.10 Circuit test and system test records ； 5.6.11 Instrumentation Equipment Handover List ； 5.6.12 Charter flight and chain system debugging records ； 5.6.13 Work related to the configuration and recording of smart instruments, DCS/SIS/PLC systems ； 5.6.14 List of unfinished projects, etc ；
