Floating Roof Storage Tank Design

The model consist of an external single deck floating roof operating in a vertical cylindrical oil storage tank which is filled with oil of density ρ 700 kg m3.

Floating roof storage tank design.

An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. Figure 3 single deck type floating roof. These are categorized as external floating roofs which are designed to meet requirements of api standards 650 appendix c. The storage tank design consists of two major designs that is 1 the shell design analysis and 2 the floating roof design.

The oil occupies 100 of the total tank volume. Types of floating roofs in storage tanks the principal types of floating roof designs which are installed in tanks which store crude and middle distillate products are summarized below. Various aspects of the floating roof tank working like the operation. The floating roof tank animation describes the working principle in the training module.

A floating roof crude oil storage tank of 100 000 bpd capacity was designed taking into consideration the available geotechnical and meteorological information of the location site. Floating roof storage tanks have their roofs actually resting on the stored liquid and rise and fall as the inventory level changes. As opposed to a fixed roof tank there is no vapor space in the floating roof tank. Specifically it is an environment friendly and economical storage tank or oil tank installed a floating roof under the vault of the tank usually made of aluminum stainless steel or other material to prevent the liquid from volatilize.

In the shell design analysis shell stress design will be performed taking into consideration of all the considerably loading including hydrostatic pressure wind loading and seismic loading. Floating roof storage tanks are inherently safer than fixed roof tanks as they essentially eliminate the creation of a vapor space in the tank above the combustible liquid. The roof rises and falls with the liquid level in the tank. External floating roof tanks are generally made of steel and only has a floating roof as the top covering.

It consists of an open topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The dimensions of the tank are 40 m diameter and 23 m height. In principle this eliminates tank breathing loss and greatly reduces the evaporative lo.
