The Calculating Programme of the Tank Floating Roof and the Specifications of the Materials Used for Crude Oil Tanks Improved

The computeer programme is made out in the way to calculate the strength and stability of an oil tank floating roof as laid down by China Science Academy. An assessment has been made of from 10000 to 50000m³ standard oil tank floating roof, which has made it clear that in storing crude oil of less corrosivity and more buoyancy, the disc and shell may further be made thinner so as to save steel by 5-6% without any reduction of its strength and stability.
