This forced the floating roof down like a piston, and some of the crude oil came up through the seal past the side of the floating roof and out of the vents on the fixed-roof tank. This oil caught fire, causing a number of pipeline joints to fail, and this caused further oil leakages. One small tank burst; fortunately, it had a weak seam roof.Design and Study of Floating Roofs for Oil Storage TanksMain two Types of Floating Roof Tanks - Single deck Floating roof In single deck roof, which is also called pontoon roof, the buoyancy is derived by the pontoons, according to API 650 [3].

Vertical and horizontal fixed roof tanks. Internal and external floating roof tanks. Crude oil, asphalt, petroleum products, organic liquids, pure chemicals, and any chemical blend. Open-top tanks. Mobile tanks truck and barge. Loading and unloading operations including splash and submerged loading. Production and mixing vessels.Working & Standing Losses: Understanding Tank Emissions floating roof oil types fixed stableThe most common types are floating-roofs and fixed-roofs. Fixed roofs are permanently affixed to the top of the tank, which creates a great deal more space for vapors to accumulate when the tank is less than full. The less material in the tank, the more room for vapors to build up. Floating-roofs float on the top of the material, guided by support legs and sealed with vapor seals around the rim.
