True or False: The purpose of water intermodal transport is to identify and eliminate problems that exist in the design and construction process, resolving them before operation begins in order to prevent issues from arising. (Correct) For the response, see \"Water Intermodal Transport Plan\". I. Objectives and Principles of Commissioning 1.1 Objectives of Commissioning: The purpose of joint commissioning is to verify whether the performance and quality of the equipment, instruments, pipelines, valves, power supply systems, etc., associated with the installation meet the design specifications, and whether the heat transfer equipment has the capacity to satisfy the process requirements. It also serves to prepare for the actual chemical processing operations, as well as to provide training for the plant’s operators and conduct a \"pre-operational drill\". 1.2 Test run principles: (1) Use deionized water in place of liquid materials, and nitrogen in place of volatile components for the test run. ⑵The operating principles for testing should be in accordance with the design conditions; if it is not possible to do so, conditions that are similar or close to the design conditions should be used. ⑶The method of trial operation is basically carried out in accordance with the standard operating procedures; if normal operating conditions cannot be met due to the use of non-real materials, then appropriate alternative conditions are selected. ⑷The conditions for water-linked commissioning are met only after it has been confirmed that the operation of all equipment associated with the unit, including process pipelines, valves, instruments and control systems, as well as electrical equipment, is normal and meets the requirements of both design and actual production. 1.3 Items to be confirmed during the joint commissioning: ⑴ Confirm that all transmission equipment is operating properly. ⑵Verify that the on-site level, temperature, and pressure readings of all tanks and towers match the indications of the control instruments, that all flow measurement values correspond to the actual calibrated or calculated values, and that the instrument control system is in good condition. ⑶Verify that all safety valves are set to the correct pressure levels and that all safety accessories are in good condition. ⑷Confirm that the on-site level gauges in all tanks and all valves are functioning properly. ⑸Verify that all construction projects comply with design specifications and meet process requirements. II. Test Run Organization Structure: To ensure that the coordinated test run is carried out in an orderly, systematic, secure, and smooth manner, a two-level test run leadership team is established. III. Conditions Required for the Test Run: The coordinated test run is conducted after cleaning, purging, and airtightness tests have been completed, after the intermediate handover tasks are finished, and after individual unit tests have been successful. The following conditions must be met prior to carrying out the coordinated test run: 1. The individual unit tests carried out by the construction unit, as well as the intermediate project handover, must be completed without any omissions or defects, and all necessary handover procedures, technical documents, and materials must be available. 2. The tag numbers of each device, as well as the medium and flow direction of the pipelines, have all been indicated. 3. The utility services are ready and have been delivered to the site area, available for use at any time. 4. The post responsibility system and other regulations have been established and issued. 5. The operators both inside and outside the position have been identified. 6. The commissioning plan and relevant operating procedures have been approved and distributed to all relevant personnel. 7. All process parameters have been approved and published by the relevant departments. 8. The commissioning personnel have received training in safety, technology, and operations as required, and have passed the relevant examinations. 9. The original records for each position and the reports required for production have been printed in full and distributed to the respective positions. 10. The mechanical, electrical, instrumentation, and analytical instruments have been verified as qualified and put into use. The automatic control instruments have not only been put into use but also verified as qualified; the operators have received training, passed the examinations, and are now able to operate them independently. 11. Good communication. 12. Fire-fighting, gas protection equipment, and combustible gas alarm systems are in good condition. 13. Common and emergency tools are fully equipped.
