How LNG Storage Tanks Work: Design, Safety, and Maintenance Best Practices

Basics of LNG Storage

• Explain LNG’s properties (liquefaction at -162°C) and why specialized tanks are needed.

Design Challenges

• Structural integrity: Highlight the GBA tank’s 65.7-meter height and 100-meter diameter .

• Material science: Use of nickel-steel alloys to handle thermal stress.

Safety Protocols

• Earthquake resistance: Reference the 2,500-year seismic resilience standard .

• Leak prevention: Double-walled containment systems and monitoring tech.

Maintenance Innovations

• Predictive maintenance using IoT sensors (link to Autodesk’s cloud-based CAE tools for simulation) .

• Case study: CNOOC’s Jinwan Phase II project (5 tanks storing 845 million m³ of gas) .

Regulatory Compliance

• Global standards (e.g., EN 14620, NFPA 59A).

• Lessons from historical incidents (e.g., 2022 Freeport LNG explosion).
