High-Performance Cryogenic Delivery Solution
DSW’s LNG Transport Trailers are engineered for the safe, reliable and efficient movement of Liquefied Natural Gas (LNG).
Designed to withstand demanding operating environments, our vacuum-insulated cryogenic semi-trailers offer exceptional
payload capacity, outstanding thermal performance and dependable road handling. Every unit is built to international
pressure-vessel standards and supported by DSW’s engineering expertise and comprehensive after-sales service.
Engineered for Performance and Safety
Our LNG transport trailer design focuses on maximising operational efficiency while prioritising user safety and ease of handling. With high-quality materials, precision manufacturing and robust vacuum insulation,
DSW trailers maintain stable cryogenic temperatures and minimise LNG loss during transit.
Inner Vessel Construction
- Manufactured and tested in accordance with ASME Section VIII Division 1
- High-grade SA240 stainless steel inner vessel for corrosion resistance
- Full radiography inspection for structural integrity
- Multiple internal baffles to enhance stability during transport
- Interior cleaned to oxygen-service standards for improved safety
- Sealed welded manway for enhanced strength and reduced maintenance
Outer Vessel & Protective Structure
- Designed to safely withstand external pressures in accordance with global cryogenic transport codes
- Equipped with dual jacket safety devices to protect the vessel in the event of leaks
- Constructed using high-strength carbon steel with stainless steel rear sections
- Integrated lifting points for safe trailer handling during maintenance
High-Performance Vacuum Insulation System
DSW’s super-insulation system offers superior thermal retention for long-distance LNG transport. The
multi-layer insulation combined with a high-vacuum annulus significantly reduces heat transfer and
minimises boil-off gas.
- Multi-layer super insulation optimised for long holding times
- Heavy-duty thermocouple tube for durable temperature monitoring
- Industrial-grade vacuum valve for sustained low-pressure performance
Running Gear & Chassis System
- High-strength, full-width chassis for improved road stability
- Air-ride suspension for smoother transport and reduced vibration
- Advanced ABS braking system for maximum safety
- Optional roll stability system and tyre inflation system
- Premium low-profile tyres and aluminium wheels
- Anti-sail mud flaps and reinforced tow-attachments
Applications of LNG Semi-Trailers
- Long-Distance LNG Delivery
Transport liquefied natural gas from terminals and production plants to regional or cross-country customers. - Fuel Supply for Remote Sites
Provide reliable LNG to mining camps, construction sites and factories without pipeline access. - Temporary or Emergency Gas Supply
Maintain supply during pipeline shutdowns, maintenance or unexpected shortages. - Power Generation Support
Feed distributed power stations, CHP units and mobile power systems that require stable fuel. - LNG Vehicle Fuel Distribution
Deliver LNG to refuelling stations and support mobile refuelling for LNG-powered trucks and buses. - Marine LNG Bunkering
Onshore and mobile bunkering for LNG-fuelled vessels, ferries and offshore craft. - Industrial Backup Fuel
Serve as backup energy for heavy industries such as steel, glass, ceramics and chemicals. - City Gas Distribution
Supply satellite gasification stations for towns, industrial parks and new developments lacking pipelines. - Seasonal Heating Support
Provide extra LNG during winter peaks to support district heating systems. - Cross-Border LNG Trade
Enable flexible international land transport where terminals or pipeline links are absent.
