the thermal stress on the floating roof could cause damage,strain and temperature measured on the actual tanks floating roof by using optical fiber gauges.Thermal stress analysis and fracture estimation were also carried out as additional analysis.Crude oil storage tanks types,design,dimensionsAs the name of the tank suggests,this cylindrical steel shell has a floating roof,meaning that it floats on top of the liquid that is in the tank.This is a very interesting concept.When the crude oil levels are low,then the position of the roof will be low as well.When there is more crude oil being stored in the tank,then the level of the roof rises to match the level of the oil.Floating roof tanks are more ideal for the storage of large quantities of crude oil.DESIGN RECOMMENDATION FOR STORAGE TANKS ANDcylindrical steel tank is the most common form of storage tank and its normal failure mode is a the sloshing phenomena and pressures by the sloshing on the tank roof have been presented. equations which give approximate stress produced by this pressure are given in this 2010 publication.
