Which tank type has a geodesic dome on top?

Which tank type has a geodesic dome on top?

• A. Cone roof tank
• B. Non-pressure tank
• C. Floating roof with geodesic dome
• D. Cryogenic fixed tank

Answer: (C)

A geodesic dome on top points to a roof design used on floating-roof tanks. Floating roofs sit on the liquid surface and can incorporate dome-shaped structures to house vents, decking, and related components while minimizing vapor loss. That combination—a roof that floats plus a geodesic dome—identifies a floating roof with geodesic dome. Fixed-cone top tanks have a stationary cone-shaped roof, not a dome on a floating roof. A non-pressure tank is a broad category that may have a fixed top, not a domed floating roof. A cryogenic fixed tank is designed with heavy insulation and a fixed top for very low temperatures, again not featuring a geodesic dome on a floating roof.
