Double Skin
Enhanced Protection for Fuel Tanks in Power Generation
Definition
“The extra layer inside a fuel tank and piping that helps to reduce the chance of a leak.”
A double-skinned (double-wall) fuel tank features two layers of containment to prevent leaks and environmental contamination. These tanks are commonly used in generator fuel storage systems, ensuring safety, durability, and compliance with environmental regulations.
Why Are Double-Skinned Fuel Tanks Important?
1. Prevents Fuel Leaks & Spills
- The secondary outer layer acts as a backup containment system in case of inner tank failure.
2. Ensures Environmental Protection
- Reduces the risk of ground and water contamination from diesel or fuel leaks.
3. Meets Safety & Regulatory Standards
- Required for industrial, commercial, and standby generator fuel storage in many regions.
4. Increases Durability & Longevity
- Resistant to corrosion, impact damage, and harsh weather conditions.
Types of Double-Skinned Fuel Tanks
| Type | Function | Common Use |
|---|---|---|
| Steel Double-Skin Tank | High-strength protection from physical damage. | Industrial generator fuel storage. |
| Plastic & Composite Double-Skin Tank | Lightweight, corrosion-resistant. | Residential & small commercial applications. |
| Underground Double-Skin Tank | Designed for buried fuel storage, with leak detection. | Large-scale fuel storage & refuelling stations. |
| Above-Ground Double-Skin Tank | Easy inspection & maintenance access. | Emergency backup generator fuel storage. |
How Do They Work?
- Inner Tank Stores the Fuel – Holds diesel or other fuels for generator operation.
- Outer Shell Provides Secondary Containment – Prevents leaks from reaching the environment.
- Leak Detection Systems (Optional) – Alerts users to potential fuel breaches for early maintenance.
Common Applications of Double-Skinned Fuel Tanks
- Backup & Standby Generators – Ensures safe fuel storage for emergency power.
- Industrial Power Systems – Supports continuous fuel supply in factories and plants.
- Remote & Off-Grid Power Solutions – Provides secure fuel storage for isolated locations.
- Renewable Energy Hybrid Systems – Stores fuel for diesel backup in solar/wind hybrid setups.
Key Points
Double-skinned fuel tanks provide enhanced safety, environmental protection, and compliance for generator fuel storage. Their leak prevention capabilities make them a reliable choice for backup power, industrial sites, and critical energy systems.
