Selecting a Chinese EPC contractor for an overseas LNG or natural gas project is a technical and commercial evaluation process. The evaluation standard is the contractor’s ability to convert feed-gas data, product specifications, plant capacity, environmental requirements, and site conditions into a complete operating facility.
An equipment supplier is responsible for individual machines, skids, tanks, or equipment packages. A full-lifecycle natural gas EPC contractor is responsible for process engineering, equipment integration, procurement, construction management, commissioning, performance testing, and operation support.
This buying guide defines the selection framework for LNG liquefaction plants, natural gas processing facilities, LNG regasification stations, gas boosting stations, LPG projects, small-scale LNG receiving terminals, and related gas infrastructure.
A complete project basis is the starting point of EPC contractor evaluation. Every technical proposal is assessed against the same process boundary, production target, feed-gas conditions, and delivery scope.
Feed Gas Conditions
Feed-gas conditions consist of composition, pressure, temperature, flow rate, water content, acid-gas concentration, heavy hydrocarbons, dust, and compressor oil.
Product Requirements
Product requirements define pipeline gas, LNG, LPG, condensate, helium, methanol, recovered carbon dioxide, or an integrated multi-product system.
Facility Scope
Facility scope includes gas treatment, compression, liquefaction, storage, regasification, utility systems, automation, metering, and downstream delivery interfaces.
Delivery Structure
The delivery structure defines engineering services, equipment supply, technical services, EPC, EPCM, or complete turnkey delivery.
A complete project basis establishes a measurable standard for technical comparison, commercial evaluation, schedule control, and final acceptance.
A natural gas EPC contractor assumes responsibility for the complete facility rather than individual equipment packages.

This technical range defines Jereh Hengri’s role in integrated projects containing treatment, liquefaction, storage, utilities, compression, and product-recovery systems.
Process-package design is the technical foundation of a natural gas facility. It establishes the process flow, heat and material balance, equipment duties, utility demand, operating range, control philosophy, and plant performance targets.
Process Ownership
Process ownership means that the EPC contractor develops and controls the core process package under one unified engineering system.
Design Customization
Design customization aligns the process configuration with feed-gas properties, product specifications, emission standards, operating conditions, and investment requirements.
Engineering Calculation
Engineering calculation includes process simulation, equipment sizing, utility calculation, operating-case analysis, and design verification.
Performance Definition
Performance definition establishes feed-gas limits, product quality, production capacity, utility consumption, testing methods, and acceptance standards.
Jereh Hengri places independent process-package design at the center of its engineering model. Its technical capability is built on proprietary patented technologies, professional engineering software, process simulation, engineering calculation, and full-lifecycle project management.
Jereh Hengri applies this engineering system from conceptual planning and process development through detailed design, procurement coordination, construction management, commissioning, and operation support.
EPC budget planning is defined by the total cost of designing, constructing, starting, operating, maintaining, and upgrading the facility.
Cost Area | Evaluation Scope |
Engineering | Process development, design depth, technical studies, and documentation |
Equipment | Main packages, materials, utilities, automation, and spare parts |
Construction | Civil works, installation, logistics, labor, and site management |
Operation | Energy consumption, maintenance demand, staffing, and technical support |
Expansion | Capacity increases, process retrofits, and utility modifications |
Initial contract price is only one component of the project budget. Lifecycle cost includes energy efficiency, equipment maintainability, commissioning duration, operating stability, spare-parts requirements, and future expansion.
The correct commercial standard is total lifecycle cost under the defined production capacity, product quality, energy consumption, emissions, and performance guarantees.
A fixed evaluation framework creates a direct comparison between technical proposals.
Technical Compatibility
Technical compatibility is the match between the proposed process, feed-gas conditions, product specification, plant capacity, operating range, and environmental limits.
EPC Responsibility
EPC responsibility defines ownership of process performance, third-party equipment, utilities, automation, construction quality, commissioning, and final acceptance.
Implementation Control
Implementation control covers procurement planning, long-lead equipment, modularization, logistics, local construction resources, operator training, and startup sequencing.
Commercial Clarity
Commercial clarity consists of the project schedule, guarantees, exclusions, payment milestones, change-order rules, documentation, and acceptance conditions.
A complete vendor comparison is based on documented engineering evidence. General company descriptions and equipment lists do not define plant-level EPC capability.
Safety and compliance form part of the technical design and contract responsibility.
The compliance framework includes:
● National and local engineering codes
● Pressure-vessel, piping, electrical, and hazardous-area requirements
● Process safety, emergency shutdown, and fire-protection systems
● Environmental, emission, inspection, and quality-control requirements
● Performance testing, operator training, handover, and acceptance documentation
Jereh Hengri’s engineering capability is defined by independent process-package development, proprietary patented technologies, professional design software, natural gas processing engineering, EPC project management, commissioning, and operation support.
Project compliance is established through the applicable code list, equipment standards, design documentation, inspection procedures, testing requirements, and acceptance criteria written into the contract.
Overseas implementation is the coordination of process engineering, local regulations, logistics, site construction, commissioning, and operator handover.
Site Engineering
Site engineering includes climate conditions, geological data, available utilities, plot limitations, construction resources, and local infrastructure.
Modular Delivery
Modular delivery defines equipment dimensions, transportation limits, prefabrication scope, lifting requirements, and site assembly boundaries.
Local Coordination
Local coordination includes permit management, subcontractor interfaces, construction supervision, documentation, and inspection procedures.
Startup Support
Startup support includes commissioning plans, operator training, performance testing, handover documentation, and operational assistance.
Small LNG receiving terminals, LNG regasification stations, natural gas boosting stations, and distributed LPG facilities require close coordination between modular equipment, utility systems, automation, site construction, and commissioning.
The final contractor decision follows five defined stages:
1. Establish technical and process compatibility.
2. Establish process-package ownership and engineering control.
3. Establish the complete EPC responsibility boundary.
4. Establish safety, implementation, and commissioning requirements.
5. Establish lifecycle cost and contractual guarantees.
A proposal qualifies only after meeting the technical, safety, implementation, and responsibility standards. Initial price does not replace engineering capability or plant-level accountability.
