Petroleum chemical engineering supervision and acceptance is a critical phase ensuring project safety, quality, and compliance. It involves comprehensive supervision and systematic inspections throughout the process to ensure the project meets design standards and industry regulations. The supervision and acceptance work spans the entire lifecycle of the project, with key focus areas including:
Pre-construction Supervision Preparation Phase
Thoroughly review design documents, construction plans, and contractor qualifications. Verify the quality certificates of equipment and materials, ensuring compliance with standards such as GB50184 "Construction Quality Acceptance Code for Petroleum and Chemical Industry Metal Pipelines." For special processes, organize a special argumentation to confirm the completeness of the HSE (Health, Safety, Environment) management system.
**II. Quality Control During Construction Process**
Monitoring key processes such as pipeline welding, equipment installation, and corrosion protection through on-site supervision, inspections, and parallel inspections. Utilizing NDT non-destructive testing to check weld quality and adhering to SH/T3543 "Technical Document Regulations for Construction Projects in the Petroleum and Chemical Industry." Paying close attention to high-risk aspects such as gas tightness tests for high-pressure equipment and electrical equipment installation in explosion-proof areas.
Section 3: Safety and Environmental Protection Special Acceptance
Based on the "Fire Prevention Design Code for Petrochemical Enterprises" (GB50160), verify the linkage test results of fire protection facilities and check the lightning protection grounding system resistance. Inspect the operation efficiency of the wastewater treatment plant and the VOCs recovery system to ensure compliance with the "Comprehensive Management Plan for Volatile Organic Compounds in the Petrochemical Industry." Review emergency response plans and exercise records, and establish a complete acceptance file for the Safety Instrumented System (SIS).
Section 4: Technical Assessment for Completion and Acceptance
The organization designs, constructs, and inspects units to perform 'Three Inspections and Four Determinations,' verifying the consistency between the project entity and the completed drawings. The system conducts single-machine trials, interlocked trials, and a 72-hour performance assessment to confirm whether the equipment's processing capacity and energy consumption meet the contracted values. Ultimately, a receipt file is established, including a quality assessment report, HSE special certificate, and completed measurement data, providing a legal basis for the project's operation.
The supervision and acceptance work must strictly comply with the "Code for Construction Project Supervision" (GB/T50319). Process records are achieved through a digital management platform, ensuring the authenticity and traceability of acceptance data, laying a foundation for the long-term safe operation of petrochemical facilities.

II. Supervision Work Implementation
Quality Control Aspect
Conducted a total of 38 special inspections, focusing on monitoring pressure vessel welding (with a UT pass rate of 98.7%), pipeline pressure tests (up to standard), and vertical alignment of equipment installation (deviation ≤ 2‰). Utilized BIM technology to review 132 steel structure nodes, identified 5 design conflicts and coordinated resolutions.
2. Security Management
Established a three-level risk management and control system, compiled 9 chemical supervision reports, identified 9 major hazard sources. Conducted 21 special inspections for confined spaces and high-altitude work, issued 17 improvement notices, and ordered corrections twice. Achieved 298 consecutive days of safe and production without accidents, with an injury rate of 0.12 per million working hours.
3. Progress Management
Utilizing P6 software for dynamic tracking, the chemical supervision report company has completed 64.3% of the overall progress, 7 days ahead of schedule. Coordinated and resolved 3 equipment delivery delays, optimizing construction sequence to save 15 days of time.
III. Issues and Solutions
Two non-melted defects were found in the furnace tube welding of the cracking furnace's radiant section; repairs have been ordered and welding parameters have been adjusted.
2. Some construction workers are not using safety ropes properly; organized 3 special training sessions.
3. Issue of missing concrete curing records; establish an electronic patrol system for full traceability.
Section 4: Focus in the Next Phase
Enhance quality control for the cold insulation layer construction of low-temperature storage tanks
2. Preparation of supervision plan for integrated commissioning of equipment linkage
3. Enhance the digital supervision archive management system
The supervisory unit will continue to fulfill its responsibilities of 'three controls, two management, and one coordination' to ensure the project is completed on schedule. The current quality of the project is under control, and the safety risk assessment is rated at the blue controllable level.
