Crude oil storage tanks are specialized containers designed to store crude oil safely until it is transported or processed.

These tanks are an essential part of the oil supply chain, ensuring a steady supply and accommodating fluctuations in production or demand.

Types of Crude Oil Storage Tanks:

1. Fixed Roof Tanks:
   • Feature a stationary roof welded to the tank walls.
   • Used for low-volatility liquids.
   • Equipped with vents to manage pressure changes.
2. Floating Roof Tanks:
   • Have a roof that floats on the oil surface, reducing evaporation losses and minimizing the risk of explosive vapors.
   • Commonly used for volatile substances.
3. Bullet Tanks:
   • Horizontal cylindrical tanks typically used for smaller volumes or specific applications.
4. Spherical Tanks:
   • Spherical in shape, used for high-pressure storage, often for liquid gases.
5. Underground Tanks:
   • Installed below ground to save space and provide safety benefits.

Materials:

Crude oil tanks are constructed from materials like carbon steel, stainless steel, or special alloys, depending on the required strength, environmental conditions, and the characteristics of the stored oil.

Key Features:

• Capacity: Ranges from a few hundred barrels to millions of barrels.
• Safety Mechanisms: Include pressure-relief valves, firefighting systems, and leak detection systems.
• Corrosion Protection: Tanks are coated and maintained to prevent rust and chemical degradation.

Applications:

• Upstream Sector: For temporary storage of crude oil extracted from the ground.
• Midstream Sector: In refineries, pipelines, or storage terminals to manage transportation logistics.
• Downstream Sector: Before distribution for commercial or industrial use
