A permanent LNG station is a fixed installation that receives, stores, and dispenses liquefied natural gas, or converts it to gas for a defined end use. Choosing a manufacturer means evaluating more than the storage tank: the design must match your supply method, daily demand, operating conditions, safety requirements, and local approvals. At Dongzhao, we recommend starting with a project brief that defines these inputs, then asking prospective suppliers to explain their equipment scope, design assumptions, interfaces, and commissioning support.

This guide is intended for project developers, fleet operators, gas distributors, industrial buyers, EPC contractors, and procurement teams considering a permanent LNG installation. It is useful whether you are planning a new site or replacing or expanding part of an existing facility. The right supplier shortlist depends on the intended service and on how much engineering, integration, and site support you expect the manufacturer to provide.
LNG is natural gas cooled until it becomes a liquid, allowing it to be stored in insulated cryogenic equipment. At approximately atmospheric pressure, its boiling point is about −162°C; actual LNG properties vary with composition and operating pressure. As a broad reference, one cubic metre of LNG can produce roughly 600 cubic metres of natural gas at standard conditions, but the conversion depends on composition and the reference conditions used.
A permanent station receives LNG by a specified delivery method, transfers it to storage, and conditions or moves it to the point of use. A vehicle-fueling station typically includes storage and dispensing equipment, while a regasification installation adds equipment to convert LNG back into gas and control delivery conditions. These are different process duties, so buyers should identify the required output before comparing equipment packages.
Depending on the project scope, a station may include an LNG storage tank, unloading connection and transfer equipment, cryogenic pumps, piping and valves, pressure-building or pressure-control equipment, instrumentation, control systems, and safety devices. A vehicle-fueling configuration may also require dispensers, metering, and vehicle interface equipment. A regasification configuration may include vaporizers and downstream pressure-control or metering equipment.
Not every station needs the same arrangement. The supplier should describe which items are included, which are optional, and which are outside the package, such as civil works, power supply, fire protection, permitting, or downstream pipeline connections. This scope clarity helps prevent gaps between the equipment supplier, EPC contractor, and site owner.
Storage capacity should reflect expected consumption, delivery logistics, reserve policy, and the space available on site. The usable capacity and operating limits should be confirmed from the proposed equipment documentation rather than inferred from the tank’s nominal volume. Layout planning should also account for vehicle movement, unloading access, maintenance access, separation distances, and the interfaces required by local regulations.
Ask the manufacturer to explain the assumptions behind its proposed configuration, including the supply pressure, operating conditions, and intended duty cycle. If the project has seasonal demand or several user groups, request a clear account of how the design addresses those operating cases. Any proposed capacity or performance figures should be tied to stated conditions and documented calculations.
| Project application | Key system focus | Information to provide |
|---|---|---|
| Vehicle LNG fueling | Storage, transfer, dispensing, metering, and vehicle access | Fleet type, expected demand, fueling schedule, and delivery method |
| Industrial or network gas supply | Storage, vaporization, pressure control, and gas delivery | Required gas flow, outlet conditions, operating profile, and connection details |
| Combined or phased project | Process integration, control strategy, expansion interfaces, and site layout | Current and anticipated uses, phasing plan, and responsibility boundaries |
This table is a screening aid, not a design specification. A station intended for multiple duties may require additional equipment and a more detailed operating concept. Ask the manufacturer to identify which functions are covered by its proposal and where third-party equipment or engineering is required.
Prepare a written brief with the application, supply source, delivery vehicle or transfer method, demand profile, site conditions, available utilities, and target operating schedule. Include the required flow or dispensing rate and outlet conditions where these are known. If values are not yet confirmed, label them as estimates and ask suppliers to state how those assumptions affect the proposal.

Review the proposed process description, equipment list, layout concept, battery limits, and interface schedule. Ask whether the manufacturer supplies a complete package or selected components, and who is responsible for integration with civil, electrical, fire-protection, and downstream systems. A detailed responsibility matrix is especially valuable when multiple contractors are involved.
Requirements for cryogenic installations vary by jurisdiction, site, and application. Ask the supplier to identify the design codes and standards it proposes to use, the documents it can provide, and which approvals remain the buyer’s or local engineering team’s responsibility. Do not treat a general statement of compliance as a substitute for project-specific review by the relevant authorities and qualified professionals.
Request a clear commercial scope that separates equipment, engineering, transport, installation support, commissioning, training, and spare parts. Compare delivery assumptions and exclusions on the same basis, since quoted lead times can depend on the final design, approvals, and component availability. Ask how technical questions, maintenance needs, and future modifications will be handled after delivery.
The price of a permanent LNG station is project-specific because capacity, process configuration, site conditions, controls, and supply scope vary. A budgetary quotation should therefore state its design basis, included equipment, exclusions, and the information still needed for a firm proposal. Treat unusually broad or low-level quotations cautiously if they do not clarify interfaces and responsibilities.
Lead time should likewise be requested as a project-specific schedule, not assumed from a generic product description. Ask what milestones affect delivery, such as design approval, buyer-furnished data, manufacturing release, inspection, shipping, and site readiness. A supplier can only provide a meaningful schedule when the scope and approval process are understood.
One common mistake is selecting a tank capacity before confirming consumption and delivery logistics. Another is comparing proposals that use different operating assumptions or include different equipment, which can make apparent price differences misleading. Buyers can also overlook access, maintenance, and unloading requirements until late in the design, when changes may affect layout or cost.
To reduce these risks, issue the same project brief to every shortlisted supplier and ask each to list assumptions and open questions. Keep preliminary estimates separate from confirmed requirements, and request revisions when key inputs change. This creates a more useful technical and commercial comparison without implying that one standard configuration suits every site.
As a natural gas equipment supplier, Dongzhao can discuss the project information needed to assess a permanent LNG station configuration and clarify the proposed supply scope. We encourage buyers to share the application, expected demand, LNG delivery arrangement, site conditions, target schedule, and any known local requirements. With these details, our team can review the equipment needs and identify information that should be resolved before a formal quotation or design proposal.
For an initial inquiry, include the project location, intended use, estimated demand, storage expectations if known, required delivery or outlet conditions, and desired scope of supplier support. If you have a preliminary layout or technical specification, include it for review. Dongzhao can then discuss the next steps and the project-specific information needed to evaluate fit.
The right permanent LNG station manufacturer is one that can match the process and equipment scope to your application, make design assumptions transparent, and coordinate clearly with your project team. Start by defining the end use, demand profile, supply logistics, site constraints, and approval pathway, then compare suppliers against the same brief. Contact Dongzhao with these project details to begin a practical discussion about configuration, scope, and the information required for the next stage.
