Floating roof tanks are broadly divided into external floating roof tanks (usually referred to simply as floating roof tanks, or FR tanks) and internal floating roof types (IFR Tanks). IFR tanks are used for liquids with lower flash points (e.g., jet fuel, petrol, ethanol). They are essentially cone-roof tanks with an internal floating roof ...
A fixed roof tank is a type of storage tank, used to store liquids, consisting of a cone- or dome-shaped roof that is permanently affixed to a cylindrical shell. Newer storage tanks are typically fully welded and designed to be both liquid- and vapor-tight. Older tanks, however, are often riveted or bolted, and are not vapor tight.
The storage tanks at an oil terminal may include fixed roof tanks, internal floating roof tanks [10] and external floating roof tanks. [1] Floating roof tanks are generally used for more volatile products to reduce evaporation loss. Fixed roof tanks have a vapor space above the product, which breathes in or out as the product is removed or the ...

The roof rises and falls with the liquid level in the tank. [1] As opposed to a fixed roof tank there is no vapor space in the floating roof tank (except for very low liquid level situations). In principle, this eliminates tank breathing loss and greatly reduces the evaporative loss of the stored liquid. There is a rim seal system between the ...
The tanks are numbered with tank one being the forwardmost. Individual compartments are referred to by the tank number and the athwartships position, such as "one port", "three starboard", or "six center." [1] A cofferdam is a small space left open between two bulkheads, to give protection from heat, fire, or collision. [2]
Side mounting is the most common placement of diesel tanks for trucks. This is typically accomplished with the use of brackets, straps or a combination of both for the purpose of attaching the fuel tank to the truck frame. The choice of shape is generally influenced by the need for maximum fuel capacity and the desire for a stylish look.
LNG storage tanks have double containers, where the inner contains LNG and the outer container contains insulation materials. The most common tank type is the full containment tank. [1] Tanks vary greatly in size, depending on usage. LNG terminal Canvey Island. In-ground LNG tanks are also used; these are lined or unlined tanks beneath ground ...
