An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. [1]
They are essentially cone-roof tanks with an internal floating roof travelling vertically up and down along with the liquid level. This floating roof traps the vapour from low flash-point fuels. Floating roofs are supported with legs or cables on which they rest. FR tanks do not have a fixed roof, being open at the top, and have a floating roof ...
Fixed roof tank. 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 Type 1 Mi–Sha a/k/a/ "Type 1 floating tank Ka-Mi" was the first IJN prototype produced. [4] The Type 1 led to the development of the Type 2 Ka-Mi being produced in 1942. The Type 2 Ka-Mi was designed for the IJN's Special Naval Landing Forces for the amphibious invasion of Pacific Islands without adequate port facilities, and for various ...
Internal arrangement of a Mark IX tank. As there was no time for a completely new design, the Mark IX was based on the Mark V, with the hull lengthened to 9.73 m (31 ft 11 in). The 150 hp Ricardo engine was moved to the front, the gearbox to the back and the suspension girders left out entirely.
The tank is filled with 10 inches (25 cm) of water which contains enough dissolved Epsom salt to create a specific gravity of approximately 1.25–1.26, enabling a person to float freely with their face above the water. In order to reduce thermal sensations, the water in the float tank is maintained at approximately skin temperature, around 35 ...
