Geodesic Dome
Geodesic domes for fuel storage tanks are self-supporting roofs designed to cover large-capacity cylindrical tanks. They protect the fuel from weather conditions, reduce evaporation losses, and enhance the overall safety of the site. Their triangulated design ensures a lightweight, durable structure that can withstand environmental loads.
Benefits
Reduced Evaporation Losses: Limits direct exposure to sun and wind.
Weather Protection: Prevents rainwater from entering the fuel.
Enhanced Safety: Lowers the risk of explosions by minimizing flammable vapors.
Durability: Highly resistant to corrosion, UV rays, and environmental loads.
Low Maintenance: Stable structure requiring minimal upkeep.
Advantages
Installation
- On-site Assembly: Components are assembled directly on the existing tank without interrupting operations.
- Peripheral Anchoring: Secured to the upper rim of the tank.
- Crane or Lift Installation: The dome can be lifted in one piece or in segments.
- Installation Time: Typically ranges from a few days to a few weeks, depending on the size.
Technology
- Structure: Geodesic aluminum truss.
- Cladding: Aluminum panels, sometimes anodized or painted for enhanced durability.
- Sealing: EPDM or silicone gaskets, with integrated drainage systems.
- Compatibility: Adaptable to fixed or floating roof tanks, with or without an existing roof.
Testability
- Load Calculations: Compliant with API 650 / EN 14015 standards.
- Corrosion Testing: Salt spray testing conducted on materials.
- CFD Simulation: Modeling of airflow and vapor dynamics.
- Visual and Ultrasonic Inspection: Ensures structural integrity.
Options
- Access Hatches: For inspection and maintenance.
- Passive or Active Ventilation Systems: To limit internal pressure.
- Special Coatings: Anti-static, anti-corrosion, and reflective finishes.
Certifications
- API 650 / API 653: American standards for storage tanks.
- EN 14015: European standard for atmospheric storage tanks.
- ISO 9001 / 45001: Quality management and occupational health & safety standards.
Required Information
To design a dome tailored to a fuel storage tank, the following information is required:
- Tank Diameter: in meters.
- Type of Stored Product: gasoline, diesel, kerosene, etc.
- Climatic Conditions: wind, snow, temperature.
- Applicable Local Standards: depending on the country or region.
- Access Constraints: for installation logistics.
- Desired Lifespan: temporary or permanent.
- Tank Geometry: a roundness ratio is needed.
