FIXED ROOF TANKS: Fixed roof tanks are said to be the cheapest types of oil storage container to construct. The ability of this container to store oil is based on the presence of some equipment that makes storing of liquid possible. These types of bunded storage containers consists of a cylindrical shell made out of steel with a cone-like shaped roof. Although this type of container was meant to support both liquid and vapour, old tanks have shown not to be airtight and also burst.

External floating roof tanks: This type of oil storage container mainly consists of a cylindrical shell which was made out of steel with the top end of it being opened,with a roof that lies on the surface of the stored liquid. The floating roof tends to rise and fall depending on the level of the liquid{oil} inside. The floating roof is constructed by welded steel plates and is mainly of different types. Pan doubled deck pontoon

Internal floating roof tanks: This type of oil storage container has both a floating and a permanently fixed roof. There are basically of two types, one of which the permanently fixed roof is supported by vertical columns and the other whereby the fixed roof is not supported any internal columns.

Domed external floating roof tanks: This type of oil storage container has a heavier type of deck used in the internal roof as well as in the external roof of the tanks.

Horizontal Tanks: These types of oil storage container are constructed for both underground and above ground use. The construction of the container makes use of steel, over layers of glass fibre with steel or reinforced glass fibre polyester, these type of containers are mostly small but are of high structural integrity.

LNG storage tank: Liquefied natural gas storage tanks is a type of oil storage container which is specialized in the storage of Liquefied natural gas. LNG tanks are mostly found above ground in LNG carriers. One of the characteristics of LNG tank is its ability to store at a very low temperature of about -165 degree c.

Variable vapours space tanks: This type of oil storage container is equipped with reservoirs of expandable vapours to accommodate fluctuation in vapours volume which is a result of temperature and barometric pressure changes

Pressure tank: This type of oil storage container that can theoretically be in any shape, but sizes are usually given by sections of a cone, spheres and cylinders which are common shapes that are mostly used.
