Key Features
On-Site Commissioning (<48 Hours): Cryogenic tank, submerged pump, vacuum piping, vaporizer, and dispenser are pre-piped, pre-wired, and factory-tested within a single ISO enclosure to minimize site-work costs.
17-Day Ventless BOG Retention: Integrated automated boil-off gas (BOG) re-condensation loop maintains internal pressure below design limits during standby, eliminating atmospheric venting for up to 17 continuous days.
Ambient Adaptation (-40°C to +50°C): Engineered for continuous rated LNG output across extreme temperature ranges without requiring auxiliary ambient utility heating or external cooling infrastructure.
Direct-on-Grade Installation: Self-supporting structural steel container frame distributes mechanical loads evenly, allowing direct placement on engineered gravel pads or asphalt without poured-concrete foundations.
Practical Applications
Logistics Corridors: Heavy-duty trucking terminals and freight refueling hubs.
Marine & Ports: Marine bunkering stations for LNG-powered vessels and port authority fleets.
Mining & Off-Grid Power: Fueling infrastructure for mining haul fleets and localized gas-fired power generation units.
Fleet Transition: Temporary or interim fueling setups for commercial transport fleets undergoing alternative fuel trials.
Standardized Component Interchangability: Built exclusively with field-proven cryogenic hardware, including RegO valves, Cryostar pumps, Flowserve actuators, and Emerson Rosemount transmitters.
Safety & Lifecycle Support
Fail-Safe PLC & <2.0s ESD Isolation: Driven by a Siemens S7-1500 fail-safe PLC with industrial gas-control logic; multi-point Emergency Shutdown (ESD) isolates the cryogenic core via pneumatic valves in less than 2.0 seconds.
Remote Telemetry & Gas Detection: Integrated methane and flame sensors paired with cellular gateways for real-time remote monitoring of tank levels, vacuum pressure, and leak alerts.
Commercial Procurement Terms: Minimum Order Quantity (MOQ) of 1 unit, with a fixed factory lead time of 16 weeks from formal engineering drawing sign-off to FOB port delivery.
10-Year Parts Availability: Minimum 10-year factory availability guarantee on all custom structural components, with 48-hour air-freight dispatch for standard wear-and-tear seals and valves.
Annual Production Capacity: Dedicated cryogenic manufacturing facility with an established throughput of 120 completed containerized systems per year to support multi-unit procurement schedules.
Certifications & Compliance
International Pressure Vessel Codes
Manufactured, stamped, and third-party verified under ASME Section VIII Division 1, CE-PED 2014/68/EU, and EN 13458 standards.
Hazardous Area Certification
All onboard electrical systems, junction boxes, and instrumentation loops carry independent ATEX Zone 1/Zone 2 or IECEx certifications.
Quality Assurance & Traceability
100% Non-Destructive Testing (NDT), including Radiographic Testing (RT) and Ultrasonic Testing (UT), backed by digital Mill Test Certificates (MTC).
FAQ
Q: What real-world deployments does the containerized LNG station currently operate in?
A: The system has been deployed in heavy-duty logistics corridors and remote mining fueling points with continuous operation cycles exceeding 18 months.
Q: Has the system been independently tested by third-party certification bodies?
A: Yes, select configurations have undergone validation by internationally recognized inspection agencies such as BV and SGS for pressure integrity and leakage performance. Each tested unit is assigned a traceable inspection report ID for procurement audits.
Q: What is the expected performance degradation after long-term operation?
A: After approximately 8,000 operating hours, pump efficiency typically declines by less than 3.5%, mainly due to seal wear. Scheduled maintenance intervals are designed to restore performance to near-original levels.
Q: How is system safety verified under emergency shutdown scenarios?
A: Full ESD simulation tests are performed quarterly, verifying complete isolation of cryogenic flow within 1.8–2.0 seconds. These include valve response timing and pressure stabilization verification under load.
Q: What is the total cost of ownership over a 10-year lifecycle?
A: Estimated 10-year lifecycle cost is typically 22–28% lower than traditional fixed LNG stations due to reduced civil construction and lower downtime.
Q: How long does full commissioning take from delivery to operation?
A: Standard commissioning requires 36–48 hours including pressure calibration, leak verification, and control system synchronization.
Q: What operational environments has the system been validated in?
A: Field tests include Arctic cold-start conditions down to -38°C and desert operations up to +52°C ambient temperature.
Q: What kind of maintenance schedule is recommended for continuous operation?
A: Preventive maintenance is recommended every 4,000 operating hours, focusing on pump seals, vaporizer efficiency, and sensor recalibration.
Q: How is telemetry data secured and transmitted to operators?
A: All remote monitoring data is encrypted using industrial-grade TLS protocols with optional private APN deployment. Systems can integrate with SCADA platforms without exposing raw control logic externally.
Q: What spare parts logistics support is available globally?
A: Critical components such as valves, sensors, and pump seals are stocked for 10+ years with global air shipment within 48 hours. Standardized part numbers ensure cross-regional interchangeability.
