The design of Internal Floating Roof Storage Tanks (IFRT) in accordance with API 650 focuses on safely storing volatile liquids while minimizing vapor losses and preventing environmental hazards. API 650 is the standard for welded steel tanks for oil and other liquids, providing detailed guidelines for construction, design, and inspection.

The structure of an internal floating roof storage tank is similar to that of a cone roof tank. However, unlike external floating roof tanks, an internal floating roof storage tank features a fixed roof, which enhances the storage conditions for oil products. This design helps prevent rainwater from entering the tank and slows down the aging of the sealing ring. Additionally, the internal floating roof effectively reduces oil loss. Therefore, the internal floating roof storage tank combines the advantages of both fixed roof and floating roof tanks. According to the American Petroleum Institute, a well-designed internal floating roof is the most effective and cost-efficient solution for controlling oil evaporation losses in fixed roof tanks.

The main use of floating roof storage tank is minimize the evaporation losses and reduce the risk of fire, this tanks reduce the vapor space above the liquid level , The goal with all floating roof storage tanks is to provide safe, efficient storage of volatile products with minimum vapor loss to the environment.
