Refinery Construction · Engineering Sectors
Refinery construction refers to the development of a complete industrial facility that uses crude oil as feedstock and processes it through atmospheric and vacuum distillation, catalytic cracking, hydrocracking, delayed coking, reforming, and other process units, supported by storage and transportation, utilities, flare systems, wastewater treatment, and other auxiliary systems, to produce gasoline, diesel, jet fuel, chemical feedstocks, and other products. Its essence is a complex systems engineering endeavor involving multiple disciplines, multiple standards, long timelines, and high risks, covering the entire chain from design and procurement to construction, pre-commissioning, and startup.
Background: The center of gravity of global refining capacity is shifting eastward. Resource-rich countries in the Middle East, Southeast Asia, Africa, and Central Asia generally require "in-country resource conversion," giving rise to numerous overseas refinery EPC projects. Chinese state-owned enterprises (such as CNPC, Sinopec, China National Chemical Engineering, and China Energy Engineering) have undertaken multiple large-scale refineries under the Belt and Road Initiative, but face practical challenges including conflicts between standard systems, absence of local codes, owners' preference for European and American standards, and cross-regional supply chains. Therefore, establishing an integrated construction logic that "uses international standards as the framework, Chinese standards as support, and local regulations as the baseline" has become an industry imperative.
Scope of application: Applicable to general contracting projects for new or expanded overseas refineries, particularly where the owner adopts American or European standards but a Chinese enterprise leads design, procurement, and construction. Not applicable to purely domestic projects using only Chinese national standards or projects limited to preliminary consulting.
The most critical decision in overseas refinery construction is the standard system. A "three-tier architecture" is recommended:
| Tier | Standard Source | Applicable Content | Priority |
|---|---|---|---|
| Top | Contractually specified standards (American/European/owner corporate standards) | Process packages, critical equipment, safety systems | Highest |
| Middle | Chinese national standards (GB/SH/HG) | Civil works, piping, steel structures, auxiliary systems | Second highest |
| Bottom | Local regulations and mandatory codes | Environmental protection, fire protection, labor, permitting | Mandatory |
Key principle: Where the contract is silent, Chinese standards shall be adopted preferentially and submitted to the owner for approval; where safety and environmental protection are involved, local mandatory requirements must be satisfied.
Core refinery units include:

Equipment procurement for overseas refineries is the core of cost and risk. Categorized management is recommended:
| Equipment Type | Procurement Strategy | Risk Notes |
|---|---|---|
| Long-lead equipment (reactors, compressors) | Global tendering, order 18–24 months in advance | Shipping schedule, customs clearance |
| Static equipment (columns, tanks) | Chinese manufacturing + local assembly | Local content requirements |
| Rotating equipment (pumps, fans) | China or third countries | Spare parts supply |
| Instruments and electrical | Owner-preferred brands | Standard compatibility |
Note: Some resource-rich countries require "local content," and the percentage and determination method must be specified in the contract in advance.
Key focus areas during construction:
Common pitfalls: Local worker productivity, rainy season construction, customs clearance delays, owner-initiated changes.
HSE requirements for overseas refineries are typically higher than domestic ones:
Recommendation: Complete environmental impact assessment, fire protection, and construction permits before mobilization to avoid work stoppages and penalties.
| Comparison Dimension | Chinese National Standards (GB/SH) | International Standards (American/European) | Local Standards |
|---|---|---|---|
| Design philosophy | Conservative, high safety factors | Performance-based, allows optimization | Varies widely |
| Materials | Chinese national material system | ASTM/EN system | Often references British/French standards |
| Fire protection | GB 50160 | NFPA 30/API | Local civil defense |
| Environmental | GB 31570 | EPA/EU BREF | Local regulations |
| Application recommendation | Auxiliary systems, civil works | Process, critical equipment | Mandatory compliance |
Conclusion: Do not attempt to "go all Chinese standards" or "go all American standards." Standards should be mixed hierarchically based on contract and risk, with written owner approval.
Scenario 1: Refinery upgrade project in Central Asia
Public reports indicate that Chinese enterprises participated in refinery modernization in Kazakhstan, adopting Chinese standards for the design of atmospheric/vacuum and catalytic units, procuring critical equipment from China, and meeting local environmental requirements. The project improved local gasoline and diesel quality.
Scenario 2: Refining and petrochemical integrated project in Southeast Asia
For publicly reported refining and petrochemical projects in Malaysia and Indonesia, the owner adopted British/American standards, and Chinese enterprises served as EPC general contractors, completing modular construction and startup through a "Chinese manufacturing + international standard certification" model.
Scenario 3: Large refinery EPC in the Middle East
Middle Eastern owners generally require American standards. Chinese enterprises partnered with international licensors, designed to API/ASME, manufactured in Chinese factories, and used third-country subcontractors for site construction, achieving standard integration.

Q1: Should overseas refineries use Chinese standards or American standards?
A: It depends on the contract. If the contract is silent, proactively propose Chinese standards plus international certification; where safety and environmental protection are involved, local requirements must be met. Mixed use requires owner approval.
Q2: How to handle local content requirements?
A: Clarify the percentage, determination method, and penalty clauses during contract negotiations. Can be satisfied through local subcontracting, local procurement, and training transfer.
Q3: What to do about long-lead equipment delays?
A: Order in advance, lock in shipping schedules, set up bonded warehouses on site, and have air freight contingency plans for critical equipment.
Q4: What if the owner frequently initiates changes during commissioning?
A: Establish a change management process in the contract, confirm costs and schedule in writing, and avoid verbal instructions.
Q5: What if an HSE audit failure causes a work stoppage?
A: Conduct a compliance audit before mobilization, hire local HSE consultants, and budget for rectification costs and time.
1. Get approval before mixing standards: Any use of non-contractual standards must be submitted to the owner for written approval and documented.
2. Lock in long-lead equipment early: Order reactors, compressors, etc. 18–24 months in advance, securing suppliers and shipping schedules.
3. Plan local content early: Clarify localization percentages during contract negotiations and consider local subcontracting at the design stage.
4. Prioritize modularization: Whatever can be pre-fabricated in China should not be brought to site, shortening schedules and reducing local risks.
5. Front-load HSE compliance: Complete environmental impact assessment, fire protection, and construction permits before mobilization; hire local consultants.
6. Document change management: All owner instructions must be confirmed in writing with costs and schedule to avoid disputes.
7. Involve the commissioning team early: Have the startup team participate during construction to familiarize themselves with systems and shorten the commissioning cycle.
8. Communicate with the community early: Negotiate land acquisition, employment, and compensation in advance to avoid work disruptions.
One-sentence summary: In overseas refinery construction, standards are the framework, the contract is the baseline, local compliance is the lifeline, and integration capability is the core competitiveness.
