API 650 ABOVEGROUND STORAGE TANKS,Part I

From all types of containers storage tanks are the most used.The different types of tanks are used to store a variety of products such as crude oil and its derivatives,butane,propane,LPG,solvents,water,etc.Storage tanks are used as reservoirs to contain a sufficient reserve of any product for later use and or commercialization.7.1 Organic Liquid Storage TanksAn internal floating roof tank (IFRT) has both a permanent fixed roof and a floating roof inside.There are two basic types of internal floating roof tanks tanks in which the fixed roof is supported by vertical columns within the tank,and tanks with a self-supporting fixed roof and no internal support columns.12345NextSTRUCTURE magazine Seismic Design of Nonbuilding The impact of a sloshing wave on the tank roof or forcing the floating roof into a fixed roof is a continuing source of seismic damage to ground supported storage tanks.Occasionally,external floating roofs are forced outside of the tank shell by the sloshing wave and end up landing on the shell or having the seal catch the shell.
