Petroleum & Chemical Engineering Supervision Report

Petroleum & Chemical Engineering Supervision Report
I. Project Overview
This project is an expansion of XX Petrochemical's annual 600,000 tons of ethylene production, located in XX Chemical Industrial Park, with a total investment of 2.86 billion yuan. The construction scope includes ethylene cracking units, raw material pretreatment units, and supporting storage and transportation systems. The main construction commenced in March 2023 and is scheduled for completion in September 2024. The project is implemented under the EPC turnkey model, with the supervisory unit overseeing comprehensive quality, safety, and progress management throughout.
Section II: Supervision Work Implementation
Quality Control Aspect
Conducted a total of 38 special inspections, focusing on the welding of pressure vessels (UT pass rate 98.7%), pipeline pressure tests (up to standard), and vertical alignment of equipment installation (deviation ≤ 2‰). Utilized BIM technology to review 132 steel structure joints, identifying and resolving 5 design conflicts.
2. Security Management
Established a three-level risk management and control system, identifying 9 major hazard sources. Conducted 21 special inspections for confined spaces and high-altitude operations, issued 17 rectification notices, and ordered corrections twice. Achieved 298 consecutive days of safe production, with a百万-hour injury rate of 0.12.
3. Progress Management
Using P6 software for dynamic tracking, the overall progress is currently completed at 64.3%, 7 days ahead of schedule. Coordinated resolution of 3 equipment delivery delays, Heilongjiang Chemical Supervision acceptance completed, optimized construction sequence saved 15 days of time.
Section 3: Issues and Solutions
2 Cracking furnace radiant section tube welding has shown 2 un熔焊 defects; repairs have been ordered and welding parameters adjusted.
2. Some construction workers are not using safety harnesses properly; organized 3 special training sessions.
3. Issue of missing concrete curing records; establish an electronic patrol system for full traceability.
Section 4: Focus for the Next Phase
Enhance the quality control of the low-temperature storage tank's insulation layer installation.
2. Preparation of Equipment Linkage Commissioning Supervision Plan
3. Refine the digital supervision document management system
The supervisory unit will continue to fulfill its responsibilities of 'three controls, two management, and one coordination', ensuring the project is completed on schedule. The current quality of the project is under control, and the safety risk assessment is at the blue controllable level.

Petroleum & chemical engineering supervision and acceptance is a crucial step in ensuring the safe and compliant operation of petrochemical engineering projects, covering the entire process from design, construction, equipment installation to debugging. It aims to ensure that the project meets national standards, industry regulations, and contractual requirements through systematic inspections and evaluations. It mainly consists of the following key steps:
### I. Construction Quality Acceptance
Thoroughly inspect the construction quality of concealed engineering, equipment installation, and process pipeline works. Verify the quality documentation of materials, confirm the compliance of welding process assessments and non-destructive testing reports (such as X-ray, ultrasonic testing); inspect the construction techniques for pipeline anti-corrosion and insulation layers; check the installation accuracy of large equipment like storage tanks and reactors (such as verticality, levelness) and test records for sealing integrity. For explosion-proof areas, strictly review the matching of electrical equipment explosion-proof ratings with area divisions.
### Section 2: Special Safety and Environmental Protection Inspection
1. **Safety Equipment**: Review records of testing for fire protection systems (sprinklers, foam fire extinguishing devices), gas detection and alarm systems, and emergency shutdown valve interlock functions; verify the effectiveness of lightning protection grounding and static dissipation devices.
2. **Environmental Compliance**: Verify operation parameters and emission test data of wastewater treatment systems, VOCs recovery units, and flue gas incineration facilities; confirm the implementation of environmental assessment approval requirements, ensuring that facilities like temporary storage for hazardous waste and emergency ponds meet standards.
### 3. Equipment Commissioning and Test Run
The supervisor must participate in the single-machine trial run,联动 trial run, and commissioning operation, recording key parameters such as equipment vibration, temperature, and pressure, to verify the logic interlock function of the DCS control system. Pay special attention to the leak detection of high-temperature and high-pressure equipment, toxic medium pipelines, and the verification report of pressure relief devices such as safety valves and discs.
### IV. Document Integrity Review
Systematically organize construction process documents, including: design change orders, material entry inspection forms, pressure vessel supervision and inspection certificates, special operation personnel records, and third-party testing reports, to form a complete set of completion documentation as the basis for acceptance and record-keeping.
The supervision and acceptance must strictly comply with standards such as the "Construction Project Completion Regulations for Petroleum and Chemical Engineering" (SH/T3904-2014). Issue a rectification notice for any identified issues, and only after the rectification is closed can the acceptance opinion be signed. By ensuring multiple dimensions, quality hazards are eliminated, laying a foundation for the long-term stable operation of the facility. (498 words)
