Extreme Weather Impact on Self-Bunded Fuel Tanks
High Temperature Effects
Extreme heat causes fuel expansion, increasing internal pressure. While calibrated vents typically release excess vapor, prolonged heatwaves may strain these systems, potentially leading to:
- Increased emissions from frequent venting
- Seal degradation if pressure exceeds design limits
- Accelerated material fatigue in containment walls
Cold Weather Challenges
Frigid conditions present different operational concerns:
- Diesel or biodiesel thickening, altering fuel flow characteristics
- Potential filter clogging from viscous fuel
- Thermal contraction stressing tank materials (steel or reinforced plastic)
- Risk of cracks developing at welds or joints in double-walled structures
Heavy Rainfall & Flooding
Water-related events test secondary containment systems:
- Submerged vents may allow water ingress, contaminating fuel
- Potential damage to internal components from prolonged immersion
- Storm surges could shift unanchored tanks, stressing connections
- Rapid water rise may compromise anchoring systems
High Winds & Storms
Atmospheric disturbances create mechanical risks:
- Vent caps or external gauges vulnerable to high-velocity gusts
- Unanchored tanks in hurricane zones may tip, compromising seals
- Hail impacts can dent outer layers, reducing future impact protection
- Flying debris may damage ancillary equipment
Manufacturing Countermeasures: Modern tanks incorporate weather-resistant materials, reinforced anchoring systems, and temperature-adaptive components. Regular post-event inspections remain critical to verify seal integrity, vent functionality, and structural soundness.
