Fuel storage is a critical aspect of various industries, from oil and gas to agriculture and aviation. Among the different fuel storage options available, Above Ground Storage Tanks (ASTs) are commonly used due to their numerous benefits, including ease of maintenance, accessibility, and cost-effectiveness. These tanks are designed to store large volumes of fuel safely, efficiently, and in compliance with stringent regulations.
In this article, we will explore Above Ground Tanks, focusing on their design, key features, advantages, applications, and regulatory compliance. By the end, you’ll have a comprehensive understanding of what makes ASTs a preferred choice for many industries.
An Above Ground Storage Tank (AST) is a type of fuel storage tank that is installed above the ground, in contrast to underground tanks (USTs). These tanks are used to store various fuels, including gasoline, diesel, aviation fuel, and more. ASTs are typically constructed with durable materials like steel or fiberglass to ensure the safe containment of hazardous materials.
These tanks are designed to be easily accessible for both installation and maintenance. They provide a cost-effective solution for industries that require large volumes of fuel storage but need to keep the storage solution visible for monitoring and safety purposes.
Feature | Above Ground Storage Tanks (ASTs) | Underground Storage Tanks (USTs) |
Installation | Above ground, easier to install and inspect | Buried underground, difficult to inspect |
Maintenance | Accessible for easy inspection and maintenance | Requires specialized equipment for inspection |
Cost | Generally lower initial installation cost | Higher installation and maintenance costs |
Safety | Visible for easier monitoring and leak detection | Difficult to detect leaks until significant damage occurs |
Environmental Impact | Higher risk of exposure to external conditions | Less exposure to weather, but leaks can be harder to detect |
Above ground tanks are generally preferred for industries that need constant monitoring, easy access, and better adaptability to environmental changes.
Above Ground Tanks are typically made from the following materials:
Steel: A widely used material, steel tanks are durable, highly resistant to external impacts, and can store a variety of fuels. Steel tanks come in both welded and bolted forms.
Fiberglass: Fiberglass tanks offer excellent resistance to corrosion, making them ideal for use in harsh environments, such as coastal areas. These tanks are also lightweight and easy to install.
Plastic: High-density polyethylene (HDPE) and other plastics are used for smaller fuel storage tanks, typically in less demanding applications.
The design of an Above Ground Storage Tank (AST) focuses on both safety and efficiency. Most ASTs feature a double-wall construction—an outer wall designed to contain leaks in the event of a breach of the inner tank. This double-wall system ensures additional protection for both the environment and the surrounding area.
The following are common design features found in ASTs:
Double-Wall Construction: As mentioned, the double-wall design helps to minimize the risk of leaks and contamination. This design allows for secondary containment in case of fuel spills or ruptures.
Venting Systems: To ensure safe and controlled pressure release, ASTs are equipped with venting systems that regulate internal pressure and prevent tank ruptures.
Tank Linings: ASTs often feature specialized linings to prevent corrosion and extend the lifespan of the tank. These linings are especially critical for tanks storing aggressive chemicals or fuels.
Overfill Protection: This feature prevents overfilling during the refueling process, ensuring that the tank is not subjected to dangerous pressure levels.
The capacity of an Above Ground Tank varies significantly depending on the intended use. Common tank sizes range from small 1,000-gallon units to massive 100,000-gallon storage systems.
Tank Type | Typical Capacity Range | Common Applications |
Small AST | 1,000 - 10,000 gallons | Agricultural use, small fleets |
Medium AST | 10,000 - 50,000 gallons | Industrial sites, mining |
Large AST | 50,000 - 100,000 gallons | Large-scale facilities, aviation |
Above Ground Storage Tanks are customizable based on the specific needs of the industry. Custom features can include:
Heated tanks for storing temperature-sensitive fuels.
Emergency spill containment systems for hazardous materials.
Tank monitoring systems that allow real-time monitoring of fuel levels and integrity.
The safety of Fuel Storage Tanks is paramount in preventing accidents and environmental damage. Key safety features include:
Double-Wall Containment: As mentioned, the double-wall construction provides a secondary barrier to prevent leaks and spills.
Venting and Pressure Relief: This feature helps manage internal pressure and minimizes the risk of tank rupture.
Fire-Resistant Materials: ASTs may be constructed with fire-resistant coatings or materials to ensure safe operation in high-risk areas.
One of the primary advantages of Above Ground Tanks is their easy installation. Since these tanks are installed above the ground, there’s no need for complex excavation, and they can be positioned in a variety of locations, making them ideal for both permanent and temporary installations.
Maintenance is also simplified due to the accessibility of ASTs. Regular inspections can be conducted without special equipment, and any necessary repairs can be carried out swiftly.
Because Above Ground Storage Tanks are installed above ground, they offer the advantage of visibility. This makes it easier to spot any signs of leaks, corrosion, or damage, thus ensuring the safety of the environment and the people around the tank.
In general, Above Ground Tanks are more affordable to install and maintain compared to underground tanks. The absence of excavation costs and the ease of accessibility reduce the overall cost of ownership.
Oil & Gas: ASTs are commonly used to store crude oil, diesel, and gasoline at refineries, gas stations, and transportation hubs.
Mining: Mining operations require significant fuel storage for heavy machinery, and ASTs provide a safe and efficient solution for these sites.
Agriculture: Farms use Above Ground Storage Tanks to store diesel fuel for tractors and other agricultural equipment.
Aviation: Airports rely on specialized Aviation Fuel Tanks for storing jet fuel, ensuring a steady supply for aircraft.
Above Ground Storage Tanks can store a variety of fuels, including:
Diesel
Gasoline
Aviation Fuel
Propane
Lubricants and Oils
Each fuel type requires different specifications in terms of tank material, size, and safety features.
In order to ensure safe operation, Above Ground Storage Tanks must adhere to local, national, and international regulations. These regulations typically cover aspects such as installation, operation, monitoring, and maintenance. Key regulatory bodies include:
EPA (Environmental Protection Agency): Provides guidelines for the safe storage and handling of hazardous fuels.
OSHA (Occupational Safety and Health Administration): Sets workplace safety standards to protect employees from tank-related hazards.
Compliance with these standards is crucial to avoid penalties and ensure the safe operation of ASTs. Regular inspections and maintenance routines are essential for ensuring compliance.
When selecting an Above Ground Tank, consider the following factors:
Fuel Type: Ensure the tank is compatible with the type of fuel you intend to store.
Storage Capacity: Choose the appropriate size based on your storage needs.
Regulatory Compliance: Verify that the tank meets industry safety and environmental standards.
Material: Choose a material (steel, fiberglass, or plastic) that suits the operational environment.
Location and Accessibility: Ensure the tank can be installed in a convenient location for easy access and maintenance.
When selecting a vendor for your Fuel Storage Tanks, it's important to choose a reputable supplier with experience in the industry. Look for vendors who offer:
