The Skid-Mounted LNG Storage Tank is a modular LNG supply system integrating vacuum-insulated storage, self-pressurization, vaporization, pressure regulation, metering, control and safety functions on prefabricated steel skids. The integrated design reduces on-site piping and commissioning work and is suitable for industrial, commercial and decentralized natural gas supply.

Self-Pressurization Module	Pressure-building vaporizer, pressure regulating valve	Maintains tank pressure for stable LNG discharge
Vaporization Module	Air-heated vaporizer	Converts LNG into gaseous natural gas
Pressure Regulation Module	Multi-stage regulator valve group	Reduces gas pressure to the required downstream level
Metering Module	Flow meter, associated instruments	Measures gas consumption or supply flow
Odorization Module	Gas odorizer	Adds odorant where required by the application
BOG Handling Module	BOG heater or recovery device	Handles boil-off gas generated during LNG storage
Control Module	PLC control cabinet, HMI/SCADA	Provides automatic control, monitoring and alarm management
Instrument Air Module	Air compressor and air treatment components, if required	Provides instrument air for pneumatic valves
Safety Module	ESD, safety valves, gas/flame detection interface	Provides emergency shutdown and safety protection
Skid Structure	Carbon steel or engineered steel skid frame	Supports and integrates the system components

Verified Global Field Deployments

[CASE STUDY] 50m³ Skid-Mounted LNG System for South American Mining Plant
Location: High Altitude Region (3,800m above sea level)
Challenge: Extreme temperature fluctuations (-15°C to 25°C) & high seismic activity.
Solution: Custom ASME IX welded frame, anti-seismic anchor design and dual-redundant pressure regulator manifold.
Outcome: Reduced client's factory diesel fuel cost by 42% within 6 months of commissioning. Zero vacuum loss recorded after 3 years.

Skid Arrangement	Single-skid or multi-skid configuration
Piping Connections	Customized according to site interface requirements
Branding	Nameplate, documentation and packaging customization available

Factory Manufacturing

The skid-mounted configuration shifts a significant portion of assembly work from the installation site to the factory. Equipment positioning, internal process piping, valve installation, instrumentation and cable routing can be completed and inspected before shipment.
This approach can help reduce field welding, piping assembly and commissioning work, particularly where installation space or site conditions are limited.

FAQ

Q: What LNG storage capacities are available?

A: The storage tank can be engineered in different capacities according to the customer's LNG consumption, storage autonomy, transportation limitations and site conditions. Configurations from several cubic meters to approximately 100 m³ are possible for suitable projects.

Q: What information is required to receive a quotation?

A: For a technically accurate quotation, buyers should provide the required LNG storage capacity, gas consumption or peak flow, inlet and outlet pressure, ambient temperature range, power supply, installation location, applicable standards and required control or monitoring functions.

Q: How is the skid-mounted LNG system installed and commissioned?

A: The skid is positioned on the prepared foundation and connected to the LNG filling line, gas outlet, utilities, electrical supply and safety interfaces. Commissioning includes leak checks, valve and instrument verification, control-system testing and functional checks before operation.

Q: What documentation is supplied with the LNG skid system?

A: Typical documentation includes the P&ID, general arrangement drawing, equipment specifications, electrical diagrams, instrument list, pressure vessel documents, inspection records, operation and maintenance manuals, installation instructions and shipping documents. The final document package is agreed before production.

Q: What maintenance is required for a skid-mounted LNG storage system?

A: Routine maintenance typically includes inspection of valves, pressure and level instruments, vaporizer surfaces, safety devices, piping connections and control components. Maintenance intervals should follow the equipment manufacturer's instructions and applicable local regulations.

Q: Can spare parts be supplied after delivery?

A: Yes. Replacement valves, instruments, control components, seals and other applicable spare parts can be supplied according to the equipment configuration. Recommended spare parts can also be identified during project planning.

Q: What site conditions should be confirmed before purchasing?

A: The project should confirm the available installation area, foundation conditions, LNG delivery access, gas pipeline connection point, power supply, ambient temperature, ventilation, safety distances and applicable local regulations. These factors affect the final system layout and configuration.
